Stop aerial work in bad weather such as strong wind, fog or unclear sight. Three. Safety regulations for cable hoisting construction: 1. Strict preparations should be made before hoisting, and facilities such as earthworms, cable towers, cable cars, pulleys, power machines and tools should be fully accepted to check whether they meet the requirements of aerial work. 2. Establish a unified command system, organize hoisting personnel to carry out safety education, and organize special training for the operation projects with great difficulty and danger. 3. After the preparations are ready, organize the hoisting personnel to make technical disclosure, and carry out trial operation and overload trial hoisting. 4. The traction winch starts slowly, and the implementation speed is stable; When hoisting components, the hoisting winch should coordinate and control the position of components in the air, and the hoisting winch should not suddenly ascend or descend to avoid excessive bounce. When the assembly is in place, the operator should wait until the assembly is stable before operating. 5. After lifting heavy objects, it is forbidden to stand or pass under the lifting point and operation line. 6. It is forbidden to stand or pass in the triangular area of the stressed steel wire rope. 7. Cable sports cars used for lifting materials, tools and parts shall not transport personnel. 8. Climbing operators should carry tool bags with them, and they are not allowed to hang safety belts on main cables, buckle cables and cable wind ropes. Four. Safety regulations for overweight transportation of portal frames: 1. After the installation of portal frame, inspection and acceptance shall be organized according to the design regulations. In addition to the static load test, the movable gantry should be put on the track to run back and forth to check the deformation of the gantry during the movement, as well as the gauge and track flatness. 2. Brake sleepers shall be set at both ends of the transverse track at the top of the portal frame. 3. The distance between the center of the gantry and the two lifting points of the heavy objects should be consistent, so as to avoid accidents caused by the eccentricity of the gantry. 4. After the gantry is in place, put away the front and rear traction cables, and wedge the flat car wheels with wooden wedges to avoid the gantry slipping; The flat car at the top of the gantry is in place, and the components are bound as required. The height of heavy objects should be raised to more than 0.5m to avoid encountering obstacles. 5. Take off the flat car cover wood and start traction. Pay attention to smooth operation. The lifted weight shall not swing back and forth, and the speed shall be controlled within 5m/min to prevent the weight from inertia swinging. 6, in order to start and stop the electric purpose, should slowly and smoothly operate the controller; When you need to retreat, you must wait for the machine and things to stop completely before you can operate. 7. When the gantry is dismantled, safety technical measures shall be formulated. V. Safety regulations for concrete pouring: 1. Manual cart shall be used for feeding, and the cart shall not be scattered. There shall be anti-skid equipment on the transportation chute. 2. During mechanical feeding, 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. 3. After the operation, put down the hopper and fall into the bucket pit or platform. 4. Electric vibrators should use cables, and the power switch should be placed in a dry place. When multiple vibrators are operated at the same time, a centralized switch box should be set up, which should be attended by special personnel. Operators should wear safety protection articles. 5, mixer cleaning should stop, hopper ups and downs in 45-90, personnel shall not stand in the middle of the bucket drum cleaning, in case the body touches the joystick to cause an accident. Before the blender is started, make sure that no one is in the bucket. 6, hanging ropeway conveying concrete must be carried out according to the safe operation of lifting and transportation. Vi. Safety regulations for pumping concrete: 1. The concrete pump shall be set in the shed, and the installation balance shall be firm. Before the pump truck is unstable, the placing boom shall not move. Check whether the electrical equipment of the delivery pump is normal, sensitive and reliable before operation. 2. Before pumping, check the integrity of pipes, pipe joints, pipe clamps and sealing rings, and do not use damaged, cracked, deformed and poorly sealed pipe fittings. 3, pipeline layout should be smooth, high, the corner should be set firmly, to prevent cross-wiring, displacement. 4. In the process of pumping, the pipeline shall be regularly checked by special personnel. If it is deformed or cracked, it should be replaced in time to prevent cracking. 5, concrete pump found fault in operation, should immediately stop the machine for inspection, shall not run in spite of illness. 6, the operator must be familiar with and abide by the operation procedures and safety regulations of the pump truck. 7. Before disassembling the pipe joint, the residual pressure in the pipe should be released to prevent accidents caused by the pressure in the pipe.
