Civilized construction standards at construction sites?

(1) Standardization of general layout

1. Rational division of construction areas

Reasonably divide construction areas according to the conditions of the construction site. The construction area is mainly divided into: living area, construction area, warehouse area, material storage area, processing area, etc. The division should be safe and reasonable, facilitate construction, save land and reduce costs.

2． Hardening of approach roads

(1) The ground and main road in the section connecting the construction site gate and the off-site road must be hardened. The main hardening methods include pouring ordinary concrete, paving three-mud soil or laying anti-skid steel plates , to ensure that the ground is dust-free, water-free, and slippery. The driving road width is 4.5 meters wide for single lanes and 6 meters wide for double lanes. Try to form a circular connection. If site conditions limit it, a shunting site can be set up at the end.

(2) Drainage ditches need to be set up on both sides of the temporary road, and sedimentation tanks are set up at the ends of the drainage ditches, which are connected to the municipal pipe network to ensure that sewage does not flow out and there is no accumulation of water in the site. In principle, when setting up temporary roads within the site, the construction of temporary and permanent roads should be combined as much as possible (with consistent axis positions). Can greatly save costs.

(3) A car wash tank should be set up at the entrance of the road in the construction site area. The sewage treatment in the car wash tank should be degreased in the oil removal tank and discharged after secondary sedimentation.

3. Unified and standardized temporary construction materials

(1) The construction site should be organized and arranged according to the following four types of temporary buildings.

Category 1: The office area of ??the project management department is a color steel plate movable room. The office facilities should have electronic office conditions, and the conference room should be equipped with air conditioning; the walls in the office should be arranged according to the company's unified requirements, and the company's safety and quality Charts on policies, goals and corporate culture should be posted on the wall, as well as the project management department’s organizational structure, department and personnel job responsibilities, and various management objectives should be posted on the wall.

Category II: The living area facilities are masonry houses, and color steel prefabricated houses can also be used if conditions permit. When masonry is used, it must be painted white, with 80 cm wide overhanging corridors and reasonable drainage ditches, and color steel plates

Slope roofs; the use of cement board mobile houses is prohibited on site;

< p>Category III: On-site tool rooms, warehouses, power distribution rooms, etc. are masonry buildings with edge heights of 2.8 meters and color steel plate slope roofs;

Category IV: Temporary work sheds and machinery and equipment are rain-proof The shed should be paved with colored corrugated boards on the basis of a prefabricated structure that complies with safety protection to prevent rain.

(2) The height of the cornice on the first floor of the construction site and temporary living facilities should not be less than 2.8 meters, and the number of floors should be one or two. Among them, the power distribution room is a brick building and should be constructed with fireproof materials. The suspended ceiling adopts outward opening doors, and the usable area is not less than 9 square meters.

(3) All construction and temporary living facilities must go through the five processes of unified planning, design, approval, and construction acceptance by the project management department before they can be put into use.

4. Office environment beautification

(1) All offices are required to be painted uniformly white to ensure clean walls, bright windows, and neatly arranged office facilities.

(2) Concrete is poured on the indoor floor and outdoor corridors, and anti-slip floor tiles can be installed when conditions permit.

(3) Set up an open drainage ditch in front of the eaves, with a width of 100 to 200mm, and drain it to the municipal pipe network. Clean it by designated personnel to prevent mosquitoes, flies and rats.

(4) Protective measures such as laying cinders and sand heads can be used on the open space in the office area, and turf, shrubs, etc. can be planted when conditions permit.

5. Greening of the construction site

(1) The greening layout should be reasonable, economical, practical, beautiful, uniform and operable. According to the actual situation and standard requirements, if possible, the greening layout can be arranged in the vacant space on the site. Greening to beautify

the environment.

(2|) Greening methods include planting turf and flowers and arranging potted plants, etc., which require unified planning to ensure normal use of the site for construction and production.

6. Air purification

(1) A vehicle cleaning station and drainage facilities must be built on site and cleaned regularly to prevent mud, sewage and waste water from flowing out or blocking the sewer. There are no puddles in the construction site, and vehicles entering and exiting the site must do so. Use clean vehicles to avoid polluting the environment by "throwing, spilling, dripping and leaking" on the road outside the venue.

(2) The mixer shed should be fully enclosed, the feeding sequence should be correct, water spraying and dust removal measures should be set up, and ready-mixed concrete and ready-mixed mortar should be used as much as possible when conditions permit.

(3) The storage yard of earth, sand, lime and other loose materials that may generate dust should be covered with dust-proof nets.

(4) The cement warehouse should be fully enclosed, with the door facing the mixing site and road, and spilled cement should be cleaned up in time.

(5) Project construction should be completed, all materials used, and the site cleared to reduce the generation of garbage. Floor cleaning should be sprinkled with water first, and garbage should be transported out in a safe manner through special channels or special containers. It is strictly prohibited Throw in the air

Throw.

7. Operation space lighting

(1) In addition to foundation pits or floor construction work surfaces, the operation space also includes production rooms such as mixing sheds, carpentry sheds, steel bar sheds, and living operating spaces such as canteens.

(2) The first choice for lighting the operating space is to use natural light. For workplaces that must be fully enclosed, measures such as installing windows, including skylights, can be adopted, and the layout can be made with reference to the window-to-ground ratio required by the specification.

(3) Artificial lighting should be arranged in places where natural light is inconvenient, such as civil air defense basements, pipe wells, elevator shafts, and stairwells. Artificial lighting should be able to achieve brightness that satisfies operating techniques and personal safety.

(2) Standardization of temporary facilities

1. Construction site gate standards

Option 1: Recommended for use in construction sites that create provincial safety and civility standards.

The most significant feature of this plan is to set up a shaped wall on the right side of the main entrance of the construction site, brick columns on both sides of the door, and no door beams. This solution is simple and elegant, and avoids the inconvenient installation and potential safety hazards caused by the installation of door beams. The main door leaf is made of □50*50*3 square steel as the main frame and □40*40*2 as the inner grille, welded into a whole, with a galvanized iron cover. The outer side of the door leaf is painted with standard blue primer, and the middle part is printed with a white corporate logo. . The main door pillars are made of 600*600mm solid brick columns, and the embedded steel plates at the door shafts are cast with C30 concrete. A white spherical light is set on the top of the pillars, and blue slogans are written on the outer facade of the pillars. A 1200*2100mm side door is opened on the left wall of the main door pillars. , on the right side of the gate is a red-brown vitrified brick wall, with the corporate logo made of sculptures and the font of "**** Engineering Project Management Department". Landscape lights can be installed at the bottom of the styling wall as needed.

Option 2: For general engineering use.

This plan adopts the more traditional method of setting steel frame door beams on the door pillars. The method of making the door leaf is the same as the one in Plan 1. The gate pillars are made of 800*800 mm solid brick columns, and the embedded steel plates at the door shafts are cast with C30 concrete. Blue slogans are written on the outer facades of the columns. A 1200*2100mm side door is opened at the left wall of the gate pillars. A 300mm thick C30 concrete beam pad is set on the top of the column, and an 800*800*5mm steel plate is embedded for welding and fixing the door head beam. The door head beam is a steel truss beam made of L500*50*4 angle steel as the main frame and the rest is welded with L40*40*3 angle steel. The outside of the beam is wrapped with galvanized iron sheet and the outer side is inlaid with spray-painted "**** Project" Project Management Department" banner. Safety slogans are marked on the sides of the beams. Lights can be set above the door beam as needed.

2. Guard room standards< /p>

The construction site guard room is set up on the left side of the main entrance door. It is made of color steel plate room. The length*width*height is 2800*2100*3000mm, the door size is 900*2000mm, and it has two doors of 1200* 1400mm glass windows, indoor cement mortar floor, 1200mm protruding cornice near the side door of the main entrance. It is required that less than 15 safety helmets be placed in the guard room, and the job responsibilities of the guard personnel are posted.

3. Construction site enclosure standards

Option 1: Brick masonry enclosure

For housing construction projects or construction periods For projects with special needs that are more than one year old, brick masonry walls must be used at the construction site in principle. Brick fence: The height of the brick fence in the urban area is 2500mm, and the height of the fence in other non-urban construction sites is not less than 2200mm. The fence adopts a 240mm solid brick wall with solid brick columns spaced 500*300*300mm apart. A 10-20mm wide expansion joint is set next to the brick column every two spans (length 10000mm).

The inside and outside of the red brick wall are plastered and calendered with 1:3 cement mortar. The outside of the wall is painted with blue and gray-white primer at intervals according to the relevant requirements of the "Enterprise Identification System (Manual)" (the painting width is the height of the wall) twice), each span is sprayed with blue corporate logos and corporate spirit logos, and the center distance is 3300mm. Colored knife flags are arranged at intervals on the upper part of the fence.

Option 2: Profiled steel plate (or color steel plate) fence. Barriers:

For municipal roads, pipelines and other projects, profiled steel plates or color steel plate barriers can be used. The height of the barriers in urban areas should not be less than 2500mm, and in other non-urban areas, the height should not be lower than 2200mm. For repeated use of profiled steel plates, the profiled steel plates are surrounded by aluminum alloy angle steel. The company logo and corporate spirit slogan are marked with a blue background and white (or white background) at intervals on the outside of the profiled steel plate enclosure. The center distance is the perimeter of the enclosure. Twice the height. Colored flags should be placed at intervals on the upper part of the fence. For fences adjacent to urban roads, yellow and black traffic guidance signs should be painted below.

4. Construction site office standards

The housing construction site offices in urban areas adopt two-story color steel plate houses with a floor height of 2700mm. The front guardrail of the office building is marked with corporate spirit slogans, and the company logo is marked on the side. In suburbs, one-story brick and tile houses can be used as the building. Office. The building area is set according to the size of the project and the needs. The construction site office is divided into the following scales:

4.1 When the project scale is less than 50 million yuan (inclusive), the office building area should not be less than 240 square meters. The plane length should not be less than 7200mm, and the width should not be less than 5000mm.

4.2 When the project scale is more than 50 million yuan, the office building area should not be less than 300 square meters, and the plane length of the conference room should not be less than 10800mm, and the width should not be less than 5000mm. . The layout is detailed in the figure below.

(1) The construction site office should be given priority to use a two-story color steel plate room, and the construction site conference room and office rooms of each department should be set up according to functional requirements. The walls should be clear and the windows should be bright. , The office facilities are neatly and cleanly arranged;
