确保卫生间排水顺畅、不渗漏的具体措施 确保卫生间排水顺畅、不渗漏的具体措施提要：预留洞留置的位置在浇筑楼层砼前进行专项的技术复核，主要针对其位置、大小、个数进行逐个的检查 更多精品地产学堂 确保卫生间排水顺畅、不渗漏的具体措施 ①过楼板的上下水等管道，均应在土建施工时提前预留，在预留洞口的四周按结构施工说明要表明设置附加钢筋，原楼板主筋遇洞口不剪断绕过预留洞。 ②预留洞留置的位置在浇筑楼层砼前进行专项的技术复核，主要针对其位置、大小、个数进行逐个的检查，发现有偏差的及时纠正并固定牢固。 ③为确保卫生间PVc立管及坐便器PVc套管与二次浇筑的细石砼能镶接密实不渗水，除在吊模浇筑细石砼应分两次浇筑（每次浇筑完后均做蓄水试验）以外还应事先对PVc立管与砼的界面进行”毛化处理”。具体的做法是在PVc立管界面刷一层PVc材料界面胶，再在胶上粘上一层事先准备好的毛米砂粒。 ④认真支设模板（严禁用砖块、木楔或编织袋堵塞充当模板），确保地面平整或内凹5－10mm，湿润洞口四周，用c20级细石砼（干硬性）浇灌密实，上口预留20mm的凹面，刷一道防水涂料再用1∶2水泥砂浆找平，然后再进行地面面层施工。 ⑤、为确保有水房间地面不出现倒泛水，排水顺畅将采取以下技术措施：按设计本工程卫生间等有水的房间或部位，楼地面面层标高均低于相邻房间20mm，在基层施工时应从地漏出水中向四周拉放射线找坡，一般找%－1%泛水高度，在地漏四周范围做成5%的泛水坡度，地漏应低于排水表面5mm，与地面结合处应严密牢固，整齐美观。聚氨酯防水涂膜施工质量要求为表面不起泡、不流淌、平整无凹凸，颜色亮度一致，与管件、洁具地脚螺丝、地漏排水口接缝严密、收头圆滑。防水层完成后做24h闭水试验（蓄水高度不小于20mm），确保不渗漏，表面无积水，并作出检查验收记录。 Measures for the routine management of moral education in Middle SchoolsMethod of conventional management of moral education in middle schoolFirst, the guiding ideology:School moral education is an organic whole of the whole education work, always adhere to the school adhere to the moral education, education for this product, and actively promote the quality education, the school building efficient curriculum system of moral education, moral education, improve the sense of attraction and appeal, enhance the moral education work for through and timeliness.
