What is the specific content of safety management of earthwork excavation? The following Zhongda Consulting will answer your questions.

1. Safety guarantee requirements: 1. Take various measures, including safety education and learning, setting up safety production slogans, formulating safety production system, supervising and inspecting its implementation, and formulating reward and punishment system, so as to enable employees to establish the idea of safety first, constantly strengthen the safety awareness of operators, establish a safety guarantee system, institutionalize safety management and regularize education. Form a good construction atmosphere in which everyone wants to be safe, everyone understands safety and pays attention to safety at all levels. 2, establish a safety inspection system, set up a safety supervision post, immediately deal with the hidden dangers of accidents found, and make records, make corrections within a time limit, and implement them to people. 3. In order to ensure the workers' own safety, construction personnel and management personnel must wear safety helmets, safety belts, non-slip shoes and other necessary safety protection appliances during construction. Slippers, leather shoes and shorts are strictly prohibited during construction. 4, the workers engaged in hoist operation should be technical examination before taking up their posts, and they can operate only after passing the examination. Safety protection articles must be set and worn according to the regulations when working on the rack. 5. The power, lighting lines and warehouses erected on the site must meet the requirements of fire prevention, waterproof, electric shock prevention, lightning protection and explosion prevention, and be equipped with adequate fire control facilities to do a good job in temporary drainage works on site. And make the alarm sound constantly. 6, set up eye-catching signs around the construction site to prevent non-production personnel from entering the site. 7. Conduct regular fire prevention education for employees. 8. Establish a safety guarantee system. Second, the requirements of earthwork excavation 1. Before earthwork excavation, a reasonable construction plan must be formulated, which must conform to the working conditions of the design of foundation pit supporting structure and shall not be changed arbitrarily. 2, must set up the support of the foundation pit, earthwork excavation operation surface and work route design, should try to create conditions to make the supporting structure of the system can form a stress system as soon as possible, in a working state. 3, before the earthwork excavation, must find out the geological situation, and formulate corresponding emergency measures and plans according to the situation. 4. Before excavation, carefully check the environmental conditions around the foundation pit, and do not work under dangerous rocks or buildings. 5. The excavation machinery shall not work under the transmission line. When working on one side of the transmission line, the nearest distance between any part of the machinery and the overhead transmission line shall meet the requirements of safety operation regulations. 6, before mechanical excavation, should check the clutch, wire rope, etc., after the empty running normally, before operation. 7, artificial digging, before and after the distance between the operators shall not be less than 3m, pile soil should be 1m away, and the height shall not exceed 1.5m m.. 8, digging, should pay attention to the stability of the soil, found that there are cracks and collapse, personnel should leave immediately and handle in time. 9. When pipes, cables and other buried objects are found during digging, the excavation shall be stopped and reported in time, and shall not be handled without authorization. 1, excavation machinery should be parked on a solid foundation, such as poor foundation, reinforcement measures should be taken, such as walkways, excavators shall not stop and drive at 2m parallel to the hollowed-out foundation pit. 11, mechanical operation into the shovel should not be too deep, ascension should not be too hard. 12, mechanical digging depth more than 5m, or found that there is groundwater, or special changes in soil quality, should be based on the performance of the soil to calculate its stability, and then determine the slope gradient. The slope of permanent excavation slope shall be laid according to the design requirements, and the slope of temporary excavation slope that has been used for a long time shall conform to the provisions in the table if the geological conditions are good, the soil quality is uniform and the height is within, under the overall stability of the slope. 13, all kinds of pipelines in the operation area, to find out its direction, marked with obvious markers, machinery is forbidden to work around the cable'), the application of manual excavation. 14, cooperate with the mechanical operation of bottom cleaning, leveling, slope repair personnel, should work outside the radius of gyration of machinery, such as must work within the radius of gyration, must stop the mechanical operation and brake, on and off the machine personnel should contact at any time, to ensure safety. 15, earth-moving vehicles should not be near the foundation pit parallel driving, to prevent the landslide rollover. 16, when unloading soil, should be carried out after the vehicle stopped, it is forbidden to bucket from the car cab. 17, multiple mechanical excavation, excavator spacing should be greater than 1m, digging should be top-down, step by step, it is forbidden to dig the toe of the slope first. 18, construction at night, should have enough lighting, in the deep pit, steep slope and other dangerous areas should set up a red light sign, to prevent casualties. 19, earthwork excavation should avoid construction in the rainy season. When necessary, attention should be paid to: 2. The original drainage system should be comprehensively inspected, dredged or reinforced, and drainage measures should be added if necessary. Flood control measures should also be formulated in areas along mountains and rivers. 21. Earthwork excavation should be avoided in winter. If it is necessary, safety technical measures should be specially formulated to ensure the engineering quality. 22, the rainy season and winter construction, anti-skid measures should be taken for the transportation road at the scene to ensure safe transportation. 23, the operator shall not pile soil and other objects on the support, and shall not walk or stand under the support. 24, enter the site must abide by the six disciplines of production safety. 25. Pipes, cables and other buried objects found during digging shall be reported in time and shall not be handled without authorization. 26, pay attention to the stability of the soil wall when digging, found that there are cracks and collapse, personnel should leave immediately and handle in time. 27. Technical Specification for Safety in the Use of Earthwork Construction Machinery Earthwork construction mainly includes excavation, loading and unloading, transportation, backfilling, compaction and other processes. At present, the machinery used mainly includes bulldozers, scrapers, excavators (including front shovels, backhoes, draggers, grab shovels, etc.), loaders and compactors. Its basic requirements are: the use of internal combustion engine, motor and hydraulic device of earthwork machinery should comply with relevant regulations 28. When the trench filling operation approaches the slope, the shovel should not go beyond the edge. When backing up, you should first shift gears before lifting the blade for backing up. 29, when working in deep ditch, foundation pit or steep slope area, there should be someone to command, and the vertical slope height should not be greater than. 3, in the bulldozing or scarifying operation shall not be overloaded, shall not be detrimental to the shovel, bulldozing frame, scarifier and other devices, the operation should be slow and smooth. Bulldozers without torque converter should slightly lift the blade or change the low gear when there is an overload trend in operation. 31, pushing a tree, the trunk shall not fall to bulldozers and high-altitude erection. When pushing a house wall or fence, its height should not exceed. It is forbidden to push buildings such as concrete piles with steel bars or connected with foundation. 32, two or more bulldozers in the same area, the distance before and after should be greater than; The left-right distance should be greater than. When driving on a narrow road, the rear engine shall not overtake without the consent of the front engine. 33. When the bulldozer pushes the scraper to help shovel, it should meet the following requirements: 34. When entering the shovel-helping position for pushing, it should keep the same straight line with the scraper; 35, the lifting height of the shovel should be appropriate, shall not touch the bucket tires; 36, shovel should be uniform force, shall not be shoved against, should prevent the bucket after the tire jacking off the ground or make the bucket eat soil too deep; When the bucket is lifted with full load, the thrust should be reduced, and the bucket will decelerate and get out of contact after being lifted off the ground; When backing up, you should first see the rear situation clearly. When it is necessary to bypass the scraper coming directly behind and turn to the shovel-assisting position, you should bypass from the left side of the car. 37. When the bulldozer is moving, the shovel should be off the ground, and it is forbidden to drive in high gear and make sharp turns. Do not drive backwards for a long distance. 38. After the operation, the bulldozer should be driven to a flat and safe place, and the shovel should be dropped. If there is a scarifier, the claws of the scarifier should be dropped. When stopping on the ramp, put the gear lever into low gear, engage the main clutch, lock the brake pedal, and fix the track or tire. A live. 39, when stopping, should first reduce the internal combustion engine speed, shift lever in neutral, lock the hydraulic transmission.
