屋面有组织的排水,多采用水落管。不论是白铁水落管,还是铸铁管、塑料管,接近散水坡的那一段,往往由于外力碰撞,或由于自重大、固定不牢等原因,经常脱落、损坏,造成雨水浇墙,渗入室内。为避免这种现象产生,我单位在所建办公楼的每个水落管下部的散水坡上,都 Drainage is organized in roofs, and downpipes are often used. Regardless of whether it is a cast iron pipe, a cast iron pipe, or a plastic pipe, the section that is close to the water-sweeping slope is often detached or damaged due to external force collision or due to heavy self-fixing, unstable fixation, etc., causing rainwater to pour into the room. To prevent this from happening, our unit is on the scatter slope of the bottom of each downspout of the office building.
