1. Safety control: (1) Check and urge the personnel entering the construction site to wear safety protection and labor protection articles (safety helmet, safety belt, safety shoes, welding mask, insulating gloves, etc.). ) correct, and do not meet the above requirements of personnel to stop and persuade them to correct, before allowing them to enter the construction site. (2) Whether there are "three violations" on the construction site (that is, illegal operation, illegal command and violation of labor discipline), if there are three violations, it is necessary to stop and correct them promptly and decisively. (3) Whether the "protection of the entrance and adjacent sides" in dangerous parts and construction links is in place, that is, whether the rigid (steel pipe or angle steel) protective railing with a height of 1.2m is set on the edge of the beam and slab of the station structure, whether a dense mesh safety net (barbed wire) is hung outside the protective railing, and the parts that do not meet the requirements. (4) Check and be responsible for ensuring that all kinds of safety signs and safety warning signs are set in place, timely sort out the parts where signs and signs fall off, are damaged or are insufficiently set, and urge them to be restored in time to ensure that they are placed correctly. (5) For the erection and dismantling of scaffolding, aerial work of bridges, tensioning work and construction work on aerial work platforms, the construction workers must wear safety helmets, safety ropes (life-saving ropes), safety buckles and other protective articles, and the work platforms must be covered with scaffolding and fixed firmly to prevent trampling. Those that do not meet the requirements should be urged to correct in time, and the dangerous operation parts should be monitored throughout. (6) Hoisting safety: (1) Before hoisting, check whether the wire rope for hoisting is broken, insist on stopping the operation, and urge to replace the new wire rope; Check whether the safety buckle at the crane hook is invalid, and whether the lifting ring and lifting ring are deformed or cracked. If there is any problem, resolutely stop risky illegal operations, and urge them to correct and eliminate hidden dangers before agreeing to the operation. (2) The truck crane legs are fully unfolded to support the soft foundation, steel plates and big sleepers, and check the balance and stability of the crane legs. (3) When lifting heavy objects, check whether the binding point and lifting point are at the center point of the component or the balance point of lifting (try to lift 50cm off the ground before lifting, and lift it after no abnormality). Single-buckle, loose-buckle and short-short components of long members are prohibited, and hanging baskets or double-buckles must be used for binding and hoisting. (4) It is forbidden to stand when the jib and the hanging object are sent out. When hoisting components to high places or deep foundation pits, workers must be evacuated in advance to avoid them temporarily to prevent falling objects from hurting people. (5) Before hoisting, the site foreman and safety officer shall check one by one according to the above, and hoisting can only be carried out after confirmation. (6) During hoisting, the safety officer shall be on duty to prevent and stop illegal operations. (7) Temporary electricity safety: switch box of distribution box: (1) Whether the main box and the auxiliary box are locked, whether there are protective facilities (rain cover) and whether the electricity warning signs are missing; (2) Whether there is "one switch with multiple machines" in the three-level switch box, whether the PE line of electrical equipment is connected properly, and whether the equipment with metal shell and shell is repeatedly grounded and connected with PE line; (3) Whether protective measures (bushings or insulating materials) are taken at the inlet and outlet of the distribution box, and whether there are sundries in the box. According to the above points, if it does not meet the requirements, notify the on-site person in charge of the construction team or the electrician of the team to correct it in time, take temporary power outage or enclosure warning for the damage of electrical components and main cables with great safety hazards, and notify the electrician of the project department to handle it in time. Distribution line: (1) Stop pulling and connecting randomly, damaging cables, exposing connectors, soaking wires in water and mopping the floor. For bridge foundation pit construction, station foundation pit construction or wet environment construction, all cables and wires should be overhead, and electrical equipment and construction machines should have leakage protectors. (2) If the cable is broken and the connector is exposed, notify the electrician to bandage or replace the qualified cable in time. Power management: (1) Check and urge the electrician patrol records in the distribution box to be filled in in time; (2) Whether the labels on the terminals in the distribution box and the serial numbers of electrical equipment are in place and whether the electrical identification is in place. (3) Supervise and cooperate with the electrician of the project department to test the repeated grounding resistance of the primary and secondary boxes every month to ensure "three-level distribution and step-by-step protection", and supervise and check whether the machines and tools on the construction site implement the protection requirements of "one machine, one brake, one box leaking". (8) Traffic safety: (1) Whether the traffic relief facilities (guiding signs, night lights, traffic guiding signs, etc.) are perfect. ) are put in place, timely supplement and correctly put, if there is any damage, timely repair or replacement. (2) personally supervise and correct the displacement and deviation of steel plates at road holes, regularly check and timely handle the protection of laid steel plates and road holes. Cooperate with the assistant manager on site to do a good job of construction enclosure and traffic guidance. (9) Safety control of scaffolding (full formwork support): (1) The scaffolder who sets up scaffolding must wear safety helmet correctly, fasten safety belt and wear non-slip shoes (soft-soled shoes) before putting on shelves; (2) When erecting scaffolding for pier and cast-in-place beam construction, the upper and lower construction ladders should be erected synchronously, and the construction operation surface should be covered with construction scaffolding and fastened with wire, and the scaffolding should be covered with dense mesh safety net for protection. (3) When the formwork support is dismantled, it is forbidden to throw short objects directly, and centralized binding and lifting must be adopted. (10) Other safety control: (1) Working at heights refers to working at heights more than 2m from the falling height. When working at heights, facilities and platforms must be erected, construction scaffolding must be fully paved, and workers must wear safety belts. (2) During oxygen welding and cutting operations, the oxygen cylinder and acetylene cylinder shall be not less than 5m apart, and the acetylene cylinder shall not be inverted, and the distance from the open flame shall not be less than10m; Check whether the acetylene cylinder is equipped with tempering valve and whether the cylinder pressure gauge is damaged. If the acetylene cylinder is not equipped with tempering valve and anti-collision ring, construction is not allowed. If the pressure gauge is damaged, ask the construction team to replace it. (3) Iron iodine tungsten lamp and brake switch are strictly prohibited on the construction site. (4) There must be a protective cover at the inlet and outlet of the electric welding machine. If the protective cover is missing, urge the construction team to repair and replace it. The metal shell of electric welding machine must be repeatedly grounded and connected to PE line. (5) Acetylene and oxygen cylinders must be stored separately in a special protective shed, and the storage area should be protected from rain and sun. (6) When the unknown pipeline is excavated on site, it is necessary to report the situation to the assistant manager on site and take temporary protective measures in time (evacuation, warning, setting warning signs, contacting responsible units, etc.). ). In case of emergency, organize on-site emergency hedging. 2. Civilized construction management: (1) Vehicles (muck trucks) entering and leaving the construction site are strictly prohibited from taking mud and soil on the road. It must be washed in the sink, and mud is not allowed on the road; (2) Check the traffic relief signs and night lights in the construction surrounding area every day to ensure normal operation; Check whether the fixed enclosure and temporary enclosure are damaged, tilted or overturned, maintain them in time, and arrange and supervise the cleaning of garbage under the enclosure base. (3) Check and urge the construction team to cover the raw materials, processed semi-finished steel bars and small component materials on site, pile them neatly, put all kinds of signs in place, and arrange safety warning signs according to the requirements of civilized construction. (four) the site excavation is not transported in time, and it is not allowed to be piled up higher than the enclosure, and the bare soil is covered and protected to prevent dust from flying. The roads in the construction site area should be watered at any time to reduce dust, so as to keep the roads in the construction area clean and dust-free. (5) Check and urge on-site security guards and doormen to register vehicles entering and leaving the construction site, and keep the environment at the construction gate clean and tidy.
