What is the safe construction plan for manually dug piles? The following Zhongda Consulting brings relevant content on the safe construction plan of manually dug piles for your reference.

1. Basis for preparation:

1. "Technical Specifications for the Design and Construction of Highway Traffic Safety Facilities" (JTJ74-94)

2. "Highway Engineering Construction Safety Technical Regulations" (JTJ76-95)

3. "Design Documents"

4. Relevant national, provincial and municipal safety laws and regulations

II , Project Overview:

There are ***13 dug piles in this project, namely: ## The 10# pier on the left side of the bridge and the 7# pier on the right side*** 5 digging piles;# #Separate overpass 1# pier and 2# pier *** 8 dug piles.

3. Preparation plan:

1. Causes of safety accidents

The main reasons for safety accidents in pile foundation construction are as follows:

1) Ground Or objects falling from height

2) Electricity for construction

3) Lifting tools malfunction

4) Lifting tools and debris fall, holes collapse< /p>

5) Blasting

6) Toxic gas appears in the pile hole causing suffocation of personnel.

In response to the above safety accidents, our department has formulated the following safety construction regulations and taken necessary measures.

2. Safety construction measures:

First of all, the relevant provisions of the "Technical Specifications for Safety in Highway Engineering Construction" (JTJ076-95) must be strictly implemented, and the following measures must be taken:< /p>

1) Workers engaged in digging piles should select strong male young people, and must undergo health examinations and safe work training such as underground, high altitude, electricity, hoisting and simple mechanical operations and pass the assessment. Enter the construction site.

2) Before reviewing the construction drawings and excavation of pile holes, carefully study the geological data, and pay attention to possible

quick sand, piping, water gushing and harmful gases. , and formulate targeted protective measures. If there are any doubts about safe construction, a report should be made to the relevant unit in a timely manner.

3) When excavation of pile holes, first investigate and understand the changes in the ground and adjacent slopes. Where the pile hole construction platform is close to the slope, measures must be taken to reinforce the slope, remove boulders on the slope, and set up interception ditches and safety nets on the upper side to prevent rainwater from soaking the slope and boulders rolling down. The excavated earth and stone should be transported out of the country in time. No residual mud and debris shall be piled up within 2m around the orifice. In order to prevent people and objects on the ground from falling into the pile hole, guardrails and safety nets must be installed around the hole (except for the excavated position at the wellhead). Personnel who cooperate with the hole should concentrate on closely monitoring the situation inside the hole, actively cooperate with the personnel inside the hole, and stay at their posts during construction. When delivering tools and items up and down in the hole, it is strictly prohibited to throw them; strictly prevent objects from the hole from falling into the pile hole.

4) The installation and removal of all power supplies and electrical appliances in the construction site must be operated by certified electricians; electrical appliances must be strictly grounded, connected to zero, and use leakage protectors. Switch boxes and distribution rooms are exclusively used. Rainproof box cover and canopy, and equipped with fire extinguishing facilities. Electrical equipment must have a certificate of conformity, and it must be accepted before use after installation.

5) All equipment, facilities, devices, tools, accessories and personal labor protection supplies at the construction site must be inspected frequently to ensure their integrity and safe use. The electric hoist, slag bucket (cage), etc. used by workers and staff to get up and down the pile holes must be qualified mechanical equipment and equipped with automatic clamping safety devices. Safety ropes and safety belts must be fastened to prevent sudden power outages. Do not use manual rope pulling to transport people or step on pile holes under the flange of the protective wall. The electric hoist adopts a push-button switch. Special personnel will be arranged to strictly inspect before and after work and add enough lubricating oil every day to ensure that the switch is flexible and accurate; the iron chain is not damaged, has a safety buckle and is not knotted; and the steel wire rope has no broken wires. The bracket should be stable and firm, and its safe lifting capacity should be checked before use. A soft ladder or safety rope or ventilation pipe must be placed in the pile hole and extended to the working surface as the digging depth increases, as an emergency backup. Hoisting equipment must be qualified, and installation can only be used after passing inspection.

6) For construction waste transportation wire ropes and pulleys, the steel wire ropes and pulleys must be installed stably. The steel wire ropes used for transportation should not be less than ￠14mm, and the tensile force should not be less than 10KN. A tension test should be performed before use, and lubricating oil should be coated every time it is used. To reduce the friction between the steel wire and the pulley, the steel wire rope should be tensioned frequently and replaced immediately if it fails.

If the wire rope is hairless or slipping, it should be replaced immediately; the diameter of the slag bucket should not be larger than half the diameter of the pile, and the height should not be greater than 1m. The earrings of the slag bucket should be welded firmly, the hook has anti-skid insurance, and is tied firmly to the wire rope. It can only be used after testing. ;Place the slag in the slag bucket at the bottom, and leave a height of 10cm on the edge to prevent the slag from leaking out. When transporting, start when the height is about 0.5-1.0m, then stop, and use manual stabilization before transporting;

7) For rock formation blasting in the hole, the shallow hole loosening blasting method is used; during blasting, tests are first conducted outside the hole to determine the depth of the hole in the different rock formations, the amount of explosives, and the loosening area. Only after passing the test can the construction blasting in the hole be carried out; blasting Electric detonators are used for blasting, and fuses are not allowed to be used for detonation; single-eye blasting is used for blasting, and multi-eye blasting is not allowed. The holes are covered with earth bags, and the hole walls are surrounded by templates and supported and fixed; during blasting, all workers in the holes are removed from the outside of the holes. Make sure that no one is outside the pile hole and near the hole before detonating; ventilation and smoke exhaust shall be no less than 15 minutes after blasting in the hole, and the air volume shall be no less than 25L/S.

8) When the excavation depth of the pile hole exceeds 5 meters, the accumulated water in the pile hole should be drained out before starting work every day, and

and a blower or large fan should be used to send water into the hole. Wind for 5 minutes to discharge the turbid air in the hole and detect the toxic gas in the hole. It is generally appropriate to use instruments for testing, but simple methods can also be used; for example, put small animals such as rabbits or mice in the cage and place them at the bottom of the pile holes for no less than 10 minutes. After checking that the ecology of the small animals is normal, the worker Only before drilling can be carried out. When the hole depth exceeds 10 meters, the ground should be equipped with special equipment to supply air into the hole, and the air volume should not be less than 25L/S. When drilling at the bottom of the hole, the air supply volume should be increased.

9) Workers in pile holes should abide by the following regulations: ① Must wear safety helmets and insulating rubber shoes; ② It is strictly prohibited to operate after drinking; no smoking is allowed in the hole; no open flame is allowed in the hole ; ③ The holes should be rotated every 4 hours of work, and the rotation should not exceed 2 hours when working with water; ④ When excavating complex soil layers, use a hand drill or steel bars of no less than φ16mm to drill the bottom of the hole every 0.5 to 1 meter deep. Use glyph exploration to check whether there are caves, sand gushing, etc. below the bottom of the hole. Only after confirming that it is safe can you continue to dig; ⑤ Pay careful attention to all the dynamics in the hole. If you find bad signs such as quicksand, water gushing, deformation of the retaining wall, or odorous gas, The operation should be stopped and evacuated quickly; ⑥ When the pile hole is dug below 5 meters, a semicircular protective cover should be installed on the retaining wall flange about 3 meters above the bottom of the hole. The protective cover can be made of steel (wood) plate or dense The eyes are made of steel (wire) mesh. When going up and down the bucket, the operator must stand under the protective cover, stop digging, and pay attention to safety; if large rocks are being lifted, all workers in the hole should evacuate to the ground before lifting; ⑦ When drilling rocks in the hole, use Wet operations should be carried out, and ventilation, dust prevention and personal protection should be strengthened; 8. If blasting occurs in a hole, all workers must evacuate to the ground before detonating; when blasting, the hole should be covered; after blasting, air extraction, air supply or The exhaust gas in the hole must be eliminated by spraying water and other methods, and the toxic gas can be detected before drilling can continue; ⑨ After pumping water during construction, the special power supply on the ground must be cut off before the operator can drill the hole.

IV. Precautions for safe construction of manually dug piles:

1) On-site managers should carefully explain the geological conditions and groundwater conditions at the dug piles to the construction personnel, and propose possible problems. problems and emergency measures. It is necessary to be fully mentally prepared and have sufficient materials and machinery for emergency measures. Safety measures must be developed and regularly checked and implemented.

2) No more than 2 people should be working under the hole. They should wear safety helmets and gloves when working, and wear raincoats,

rain pants and wellies when there is water. An electric bell or intercom is installed in the hole to ensure signal communication between workers below the hole and those above the hole. Hammers, hoes, stones, iron rods and other items that may cause injury are not allowed to be placed around the ground hole.

3) Downhole personnel should pay attention to the changes in the hole wall. If any collapse or cracks in the protective wall are found, they should be reported promptly and support measures should be taken. If there is danger, contact signals should be sent in time to facilitate rapid evacuation. And take effective measures to eliminate danger as soon as possible

4) Ground personnel should pay attention to the contact signal sent under the hole and respond quickly and quickly. Always check whether brackets, pulleys, and ropes are secure. When hanging down, it must be hung securely, and the earth and rocks lifted up must be poured out and unloaded 2 meters away from the opening.

5) Electrical equipment such as water pumping, lighting, and ventilation during construction should have one machine, one gate, and one leakage protector. Three-core rubber wires should be used for power supply lines. The wires should be overhead and must not be dragged on the ground. And always check whether the wires and leakage protection are intact.

6) When pumping water from the hole, the drainage outlet should be more than 5 meters away from the hole, and ensure smooth drainage at the construction site.

7) Dig the hole on the same day and pour the retaining wall on the same day. When people leave the construction site, the openings must be covered and warning signs such as red lights must be set up. Before opening the hole cover for construction, harmful gases must be eliminated and tested before work can begin.

8) Dig the hole 6-10 meters deep, and ventilate the hole at least once every hour. Use special ventilation equipment to maintain ventilation if it is more than 10 meters.

9) Strictly control the amount of explosives used during blasting to prevent excessive vibrations from causing the flow of sludge in a flow-plastic state and crushing the arm to cause collapse holes. Increase the thickness of the arm in the silt layer and add additional steel bars for the arm. , steel pipe support is used during blasting. Drain the water between the silt layers, and set drainage holes in the arm guards (the outward slope of the drainage holes should not be less than 5%, the spacing should be 2 to 3m, and should be arranged in a plum blossom shape), and a water pit should be set at the bottom of the hole. Remove standing water. If the silt layer is thick and fluid, prefabricated concrete socket pipes can be used to protect the arms. The gaps between the pipe walls should be filled with cement slurry or resin cement slurry. Drainage holes should be set at the lower mouth of the prefabricated pipes to eliminate water at the hole walls. Pressure, there is a drainage pit in the base to prevent collapse holes caused by silt flow due to excessive vibration.

⑴Basic safety requirements to prevent collapse accidents:

①During grading or slope protection construction according to soil quality, the type of soil quality should be used. For shallower foundation pits, grading methods should be adopted. Measures: For deeper foundation pits, technical measures such as retaining piles and anchor rods must be considered, and professional companies must be employed to carry out protective construction.

③ There must be a safe distance when piling soil beside the foundation pit. It is strictly prohibited to pile construction materials beside the pit to prevent the vibration of the soil caused by the dynamic load from causing changes in the internal particle structure of the original soil layer.

④ During the earth excavation process, monitoring must be strengthened.

⑤ Put an end to the "three violations" phenomenon.

⑵Measures to prevent foundation pit collapse

①Strengthen monitoring of earth excavation

Before excavation, the foundation pit wall form, drainage and Require others to formulate an excavation plan and provide explanations to the machine operators. During excavation, technical personnel should be present to monitor the excavation depth and pit wall slope to prevent over-excavation. Provide timely support after excavation and blasting, and do not excavate the next section of earth before the construction of the previous section of protective wall is completed. Foundation pits in soft soil must be excavated evenly in layers, and the layer height should not exceed 0.5m.

② Strengthen the supervision of the construction quality of supporting structures

Establishing and improving the internal supporting structure construction quality inspection system of construction enterprises is an important means to ensure the construction quality of supporting structures. The objects of quality inspection include the materials used in the supporting structure and the supporting structure itself. The raw materials and semi-finished products of the supporting structure should be inspected in accordance with the relevant construction acceptance standards. The main contents include: (1) material factory certificate inspection; (2) on-site sampling inspection of materials; (3) concrete mix ratio test and strength grade inspection.

③Strengthen the control of surface water

Before foundation pit construction, the geology and pipe network conditions of the foundation pit should be understood to avoid damage to the pipe network during the construction process. Explosion or leakage occurs. At the same time, in order to reduce the penetration of surface water into the soil of the pit wall, the top of the foundation pit should be sealed with concrete. A surface drainage system should be installed at the construction site to conduct organized discharge of rainwater and construction water. Drain holes should be installed on pit walls with supporting structures to ensure that the water pressure in the soil inside the protective wall can be eliminated in time, reducing the soil moisture content, and making it easier to observe the surface water situation in the soil around the foundation pit and take timely measures. The outward slope of the drainage holes should not be less than 5%, the spacing should be 2 to 3m, and the layout should be in a plum blossom shape.

④ Carry out on-site monitoring of supporting structures

Monitoring of supporting structures is an important means to prevent the collapse of supporting structures. Prepare a monitoring plan when designing the supporting structure. The contents of the monitoring projects include: underwater displacement and vertical displacement at the top of the foundation pit, deformation of buildings (structures) on the top of the foundation pit, etc. The selection of monitoring projects should consider the safety level of the foundation pit, the deformation control requirements of the supporting structure, and the characteristics of the geology and supporting structure. The monitoring plan can be determined based on factors such as design requirements, retaining wall stability, surrounding environment, and construction progress.

The monitoring unit should regularly report the monitoring situation to the construction unit and supervision unit. When the monitoring value exceeds the alarm value, the design, construction and supervision units should be notified immediately to analyze the reasons and take measures to prevent accidents.

5. Civilized construction:

(1) Establish a high-quality construction team, continuously strengthen internal management, improve the ideological awareness of employees, and make all employees realize that this project not only requires quality The construction period is high, the construction period is tight, and the construction is difficult. It is also a key local project and is highly political in all aspects.

(2) Stimulate the enthusiasm of employees, strengthen information communication and carry out necessary coordination among different types of work, different teams and different positions, so that the construction site is always filled with unity and cooperation. , equal competition, harmonious and upward atmosphere.

(3) Do a good job in construction publicity and agitation to promote civilized construction on the construction site. The construction site must have fixed construction safety and technical slogans, project signs, and construction progress schedules. Respect the supervision engineer, warmly receive the inspection and guidance of the supervision engineer, and proactively report the project progress and project quality.

(4) Construction wastewater and domestic sewage shall not be discharged into farmland, cultivated land, irrigation canals and reservoirs. Discharge into drinking water sources is strictly prohibited. During construction, keep the site clean and sanitary, and clean up construction waste in a timely manner.

(5) Construction machinery should prevent serious oil leakage. It is prohibited to directly discharge oil pollution generated by machinery during operation without treatment, or to directly discharge oily sewage during maintenance of construction machinery.

(6) Wasteland with sparse vegetation should be used to excavate waste material with bored piles. Waste dams or walls should be built at the lower part and corners of the waste material to prevent water and soil erosion. Waste residue should be avoided as much as possible to damage or bury the trees and farmland below.

(7) Strengthen education on the protection of natural resources and wild animals and plants for construction workers, and strictly prohibit poaching and arbitrary felling of trees.

6. Safety management of manually dug piles:

Manually dug piles are a highly dangerous type of work in bridge construction, and they are highly unpredictable. So, how to safely manage the construction of manually dug piles. This is a topic that every construction manager must face seriously.

Regulations and project department safety management system.

(4) Supervision, inspection, re-education and assessment during the construction process are in place:

(1) During the construction process, safety officers and foremen play a supervisory role, If any signs of an accident occur there, we promptly organize personnel to eliminate them and emphasize that similar incidents will not happen again.

(2) During the construction period, in addition to requiring the construction team to conduct routine daily self-inspections before work (mainly checking whether the leakage protector has failed, whether the cradle frame, ropes, safety hooks, and brake switches are in good condition Damage or loss of control, whether the submersible pump motor and cable are normal or damaged, broken, etc.).

The safety officers also conduct irregular reviews and carefully observe the underground operations. The foreman keeps original records of the depth of each meter of the operation team. If any potential accidents are discovered, he immediately orders the team to make rectifications by appointing personnel, deadlines, and measures, and implements the rectifications. content.

(3) Re-educate some workers whose safety awareness has faded during the construction process.

(4) During the construction process, the work team will be assessed every day, and a reward and punishment system will be implemented. The main assessment contents are: ① Preventing falls from heights ② Preventing objects from hitting ③ Safe use of electricity for pumping water with submersible pumps ④ Correct use of seat belts, safety helmets, safety ropes, and safety hooks ⑤ Inspection and acceptance of construction machinery and tools, etc.

(5) After-shift summary and improvement work is in place:

7. Emergency measures for hole collapse

① Once a collapse or landslide accident occurs, the evacuation team should first conduct an evacuation, count the people, and determine whether anyone is missing or injured. Understand the situation of construction workers in the area before the incident and the number of workers. If any construction workers are missing or buried, organize effective excavation work immediately.

Manual excavation should be used for excavation, and mechanical excavation is prohibited to prevent machinery from causing

injury to buried persons. Try to avoid using sharp tools for manual excavation. For large and heavy objects, the handling should be reasonably organized, especially large objects that press on the buried people. Sufficient manpower must be organized to move them. Responsibilities must be clearly defined before transportation, and a designated person should be responsible for moving the buried people out.

Rescue and excavation personnel should be divided into teams, reasonably arrange manpower according to the working surface, and change shifts in a timely manner to ensure the physical strength of the rescue and excavation personnel and ensure that the buried personnel are rescued in the shortest possible time.

② If anyone is missing or injured, call the police immediately.

There are also vehicle guides to guide rescue vehicles.

③Delineate the dangerous area, arrange surveyors to observe the slope displacement and deformation, and arrange experienced technical personnel to do monitoring work. If the slope cannot be stabilized, take timely measures to deal with it.

④ When necessary, rationally organize the removal of the load on the top of the slope, and effectively support the slope surface to prevent the expansion of slope damage.

⑤ Before professional medical personnel arrive, the rescue team will provide simple rescue to the injured.

(1) Race against time to rescue the buried person, exposing the head first to ensure smooth breathing.

(2) After coming out, the person who has stopped breathing should immediately perform artificial respiration, and then perform regular cardiopulmonary resuscitation.
