我单位宿舍楼卫生间一段暗铺铸铁排水管承插接头处向外漏水,漏出来的污水顺墙根和楼板缝隙流向楼下房间,严重污染了楼下房间的墙壁和顶棚。为解决这个问题,我们曾将漏水段排水管四周掏干净后向里捶干水泥、灌水泥浆,以阻止漏出的水向四周扩散,实践证明,这种办法不能解决问题。后来我们采用浇灌沥青法,较好地解决了漏水 In the dormitory of our unit, a section of the concealed cast-iron drain pipe joints leaked out of the toilet. The leaked sewage flowed down the gap to the downstairs room along the gap between the wall and the floor, seriously polluting the walls and ceiling of the downstairs room. In order to solve this problem, we once drained the drain pipe around the leaking section to clean the cement and grout to prevent the leaked water from spreading to the surrounding area. Practice has proved that this solution does not solve the problem. Later, we used the asphalt method to better solve the leak.
