Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice. It will be hot in about twenty or thirty days. After the summer solstice, the ground is strongly heated and the air convection is vigorous, and thunderstorms often form from afternoon to evening. ZhongYuan remind you Construction of chemical and municipal pipelines in power plants industry customer friends: the weather is hot, pay attention to heatstroke prevention!

刚性防水套管预留孔洞时需遵守哪些要求

Time:2019/4/17 14:00:45

    刚性防水套管的给排水管应在其相应的方位预留孔洞。其预留孔洞尺度为:DN25及以下管道 预留孔:50mm~100mm;DN32~50 预留100mm~150mm;DN70~125 预留孔:150mm~200mm;DN150 预留孔:200mm~250mm;DN200预留孔:250mm~300mm.

 

    一切预留孔的*坐标及标高,偏移规划方位应不大于20mm.在土建底层钢筋帮扎完后,依据施工图制作预留预埋图进行预留(埋)施工,施工时要对照上、基层施工图纸,按图要求做好预留孔洞。

    厨厕的预留孔洞应留意洁具的方位以及厨厕内的线、管安置,避免在装置时损坏线、管。楼地上的孔洞的预留选用长20cm左右的钢短管外缠塑料布确认预留方位后固定于墙体或板体钢筋上,并及时复核其方位,确保方位准确无误。

    密切配合土建,待砧板初凝后,应及时从板大将套管抽出,以确保预留孔洞的成型。一起,套管也可屡次重复使用,剪力墙上的套管待土建拆模后进行复查整理。如需预埋铁件与孔洞,应事前画出预埋图,并与土建施工单位一道洽谈,确认预留预埋时刻与办法。
