为了防止厕浴间、盥洗室地面渗漏水,设计一般作法是在砂浆找平层上铺贴一毡二油防水层,由于纵穿地面立管多,离墙角近,立管根部粘贴困难,不易做好,往往引起渗漏。我们采用无机铝盐复合防水砂浆抹成刚性防水层,并在立管根部地漏处采用刚性与弹性材料相结合的做法,代替一毡二油防水层的施工方法,取得了明显的效果。该项技术应用于虎东小区3号和4号宿舍楼工程(建筑面积
In order to prevent leakage of water in the toilet room and bathroom floor, a common method of design is to apply a felt and oil waterproof layer on the mortar screed. Since there are many vertical riser pipes and it is near the corner of the wall, it is difficult to attach the root of the riser. Doing well often causes leakage. We used inorganic aluminum salt compound waterproof mortar to apply a rigid waterproof layer, and used a combination of rigid and elastic materials at the floor drain of the riser to replace the construction method of a felt and oil waterproof layer, and achieved remarkable results. This technology is applied to the construction of dormitory buildings No. 3 and No. 4 in Hudong Community (building area
