地下防水结构中,阴阳角、穿墙管、变形缝等部位,是防水结构的薄弱环节,卷材铺贴比较困难,而且一旦出现渗漏不易修补。所以,在这些部位的施工操作中,要认真细致,一丝不苟,严格按规定操作,才能保证整个防水工程的质量。一、转角处铺贴建筑物平面与立面交接的转角处,不允许卷材有搭接,其搭接 In the underground waterproof structure, the yin and yang angles, the through-wall pipe, the deformation joint and other parts are the weak links of the waterproof structure. It is difficult for the coil to lay, and it is difficult to repair once the leakage occurs. Therefore, in these parts of the construction operations, we must be careful, meticulous, strictly in accordance with the regulations in order to ensure the quality of the entire waterproofing project. 1. Corners at the junction of the plane of the building and the facade are not allowed at the corners. No overlapping of the coils is allowed.
