What are the safety management regulations for subgrade construction?
It is very important to clearly analyze the safety management regulations of subgrade construction. The regulations are formulated for safety, and the safety of construction personnel is the basis of construction efficiency and project quality. Zhong Da Consulting will explain the safety management regulations of subgrade construction for you.

1. General safety regulations: 1. Before the project starts, the construction unit shall check the design documents in detail, and formulate corresponding safety technical measures according to the topography, geology, hydrology and meteorology of the construction site while compiling the construction organization design. 2, the construction personnel must accept safety education, familiar with and abide by the engineering safety technical operation procedures, engaged in electrical, lifting, construction, boiler erection work. Pressure vessels, welding, vehicle and machinery driving, blasting. Gas detection and other special types of personnel should be certified after professional training. 3. When new technologies, new processes, new equipment and new materials are adopted in the construction, corresponding safety technical measures shall be formulated. 4, the operator before mount guard, must be in accordance with the provisions, correctly wear and use protective equipment, don't wear a helmet, it is forbidden to wear slippers, barefoot into the construction site. 5. Important safety facilities must follow the principle of "three simultaneities" with the main project, that is, simultaneous design, simultaneous approval, simultaneous construction and simultaneous use. 6, all kinds of machinery and equipment used in the construction, labor protection articles, should be regularly checked and necessary inspection. It is forbidden to use unqualified machinery and equipment and labor protection articles. 7, the construction site set up the necessary fire equipment, construction personnel familiar with its performance and usage. II. Safety regulations in the construction preparation stage: 1. The construction site should be conducive to production and life, meet the requirements of flood control, fire prevention, explosion prevention and disaster prevention, and have civilized production and civilized construction conditions. 2. Temporary facilities on the construction site should be located in areas with good hydrogeological conditions, and temporary works such as transportation roads, production, living, houses, inflammable and explosive warehouses, material stacking, electric power and communication lines should be prepared, and reasonable arrangements should be made in accordance with relevant safety regulations. 3, the construction site should set up safety signs, shall not be removed without authorization. 4. The production and living rooms shall keep a safe clear distance according to the requirements of fire prevention. General prefabricated houses are 7m, and iron houses are 5m. The clear distance of temporary boiler room, power generation room, power distribution room, iron workshop, kitchen and other houses shall not be less than 15m. 5, inflammable and explosive goods warehouse, generator room, substation, necessary safety protection measures should be taken, it is forbidden to use flammable materials. The temporary small oil depot on the construction site is 50m away from the living quarters, and the setting of external fences and explosive depots shall comply with the relevant state regulations and be approved by the local management department. 6, in the forest construction survey, to comply with the provisions of forest fire prevention, it is forbidden to fireworks. 7, when working near the high voltage line, must keep enough safe distance. 8.

It is necessary to clearly define the division of labor, and it is not allowed to break the tree barrels across the trunk. When cleaning high slopes, safety ropes and safety belts should be used. Three. Safety regulations for earthwork excavation: 1. Before construction, clear trees, weeds and pumice within 3 to 5 meters above the slope, repair the construction access road and open the mechanical access road; Protective fences should be set up in dangerous areas of high slopes to remove pumice on the surface. 2, the operator should keep enough safe distance, labor and machinery are not allowed to work at the same time, man-machine cooperation construction should be staggered. 3, top-down construction, it is forbidden to dig "fairy soil" pry "fairy stone". Construction shall be carried out according to the standard of primary joint with design slope. 4, high and steep slope area construction, construction personnel should wear safety helmet, use safety rope, it is forbidden to double operation. 5. Operators on the slope should clear loose earth and stone in time, and warning signs should be set on the roads within the scope of abandoned soil and rolling stones under the slope, and it is forbidden to pass during operation. 6, found in the construction of the mountain have signs of sliding, collapse endanger safety, should suspend the construction, the withdrawal of personnel machines and tools. 7. When the machine is in a dangerous area, warning signs must be set up, and designated personnel should stand in the position where the operator can see clearly. 8. When the machine is working in the slope ditch, it should keep a necessary safe distance from the edge, so that the wheels can be pressed on the solid ground. 9. Cooperate with mechanical operations such as bottom cleaning, leveling and slope repairing. , should work alternately with the machine, and the personnel on and off the machine should cooperate closely. When auxiliary work must be carried out at the same time within the scope of mechanical operation, auxiliary personnel should stop mechanical operation before entering.
