What are the implementation details of safety supervision in mixing plant construction?

The mixing plant (stabilized soil and asphalt mixture processing plant) is full of large-scale machinery, with criss-crossing roads and pipelines, numerous work processes, and three-dimensional intersections of aerial and ground operations, which are important sources of danger for safe production. 1. The reasonable arrangement of machines and tools in the mixing plant has a great bearing on the safety of life and property of construction workers. Safety must be regarded as a top priority to ensure safe production in the mixing plant. 2. All transportation roads, material stacks, power communication lines, production and living buildings and their temporary facilities in the mixing site should be reasonably arranged in accordance with relevant safety regulations. 3. The production and living houses, substations, generator rooms, oil depots, etc. on the site should be set up on higher foundations, the floors should be properly hardened, and should meet the requirements of fire protection, flood protection, wind protection, explosion protection, and earthquake protection. 4. Safety signs and safety propaganda slogans should be set up at the construction site and must not be removed without authorization. 5. It is strictly forbidden to use flammable materials in the construction of generator rooms and oil depots, and necessary safety measures must be taken. The temporary oil depot must be 50m away from the living area and surrounded by fences. 6. Higher buildings on the construction site, such as mixing buildings, cement tanks, gantry frames, etc., should be equipped with lightning protection devices. 7. All temporary power supply systems such as temporary lines, various electrical equipment, and installed transformers installed on the site should comply with relevant regulations of the power industry, and the substation should be equipped with high-voltage appliances and fire-extinguishing equipment. 8. Routine maintenance, troubleshooting, and repairs of the temporary power supply system must be performed by qualified electricians. Others are not allowed to operate at will. 9. The mixing plant must have its own power supply and interlock protection with the power grid. 10. The generator should be equipped with grounding protection with a resistance of no more than 4Ω. Inflammable and explosive items should not be placed nearby, and the machine room should be equipped with fire-fighting equipment. 11. The mixing station should be installed on a solid and stable foundation with sufficient bearing capacity, and a working platform and protective railings should be installed for operation. 12. A special construction safety plan must be prepared for the installation (removal) of the mechanical equipment of the mixing station, and the construction must be carried out by a professional unit with construction qualifications. After the construction is completed, it must be inspected and accepted and a "qualification certificate" is issued by the authorized unit before operation. 13. After the belt conveyor is started without load, the operation of each part and the tightness of the belt should be checked. After the operation of each part is normal and the rated speed is reached, the materials are evenly loaded. 14. It is strictly prohibited to carry out repairs and adjustments while the belt conveyor is in operation, and operators are not allowed to cross the conveyor belt. Cut off the power supply after shutdown. 15. When the loader is loading materials, no one is allowed to stand within the moving range of the bucket, and no one is allowed to stay or pass under the bucket. 16. When loading materials on a manual trolley, do not let go. Anti-skid facilities should be installed on transport ramps. 17. Before operating the concrete pump (pump truck), check whether the delivery pump and electrical equipment are normal, sensitive, and reliable. 18. Before pumping, check the integrity of pipelines, pipe joints, pipe clamps, and sealing rings.
