What are the technical requirements and measures for construction in rainy season and typhoon season?
technical measures for construction in rainy season and typhoon season a. In rainy season, there should be a certain amount of rain-proof materials (ponchos, plastic films, etc.), and outdoor construction should be suspended if the rainfall is too heavy. In particular, if concrete is cast, a fortification canopy must be built. And cover the concrete surface layer in time, and handle the surface layer in time after the rain. B, drainage ditches around the work site should be cleared in time, and no less than four pumps should be prepared. Strengthen pumping in rainy season and flood season to ensure smooth construction. Appropriate anti-skid measures should be taken to ensure safety in the workplace, transportation road, scaffold and steel platform. C, before concrete is cast, you should know the weather forecast for 2-3D, try to avoid heavy rain, and properly consider the design position of several construction joints according to the structural situation, in case of shutdown caused by sudden heavy rain during pouring. D, if steel welding is necessary in rainy days, it can be carried out only after building a fortification canopy. E, mechanical and electrical equipment should take measures to prevent rain and flooding, install grounding safety device, the leakage protection device of motor switch box should be reliable, mechanical equipment should have a canopy, its power supply circuit should be well insulated, and there should be perfect protection to zero. F, installed metal pipes should be checked for corrosion, and anti-corrosion measures should be taken. G, arrange the implementation of special typhoon and flood control materials, and put them in the special equipment warehouse for standby, and shall not be used for other purposes. During typhoon and flood prevention, no less than 2 people shall be arranged to be on duty in turn every day, and the danger shall be reported in time, and the forces shall be organized to rescue in time. H, before the typhoon comes, strengthen the safety inspection of tower crane, scaffold, derrick, etc., to ensure that the attached wall and cable wind rope are safe and firm, and add cable wind rope for temporary fixation when necessary. Remove objects on the top construction surface that may be blown off by strong wind. All work should be stopped when the typhoon comes.
