在工业与民用建筑中,经常遇到中小型地坑工程,这种地坑工程必须做好防水处理。常用的卷材防水由于施工质量和卷材层在施工中易被损坏等原因而发生渗漏,修补非常困难,严重的必须返工。基于以上情况,我们在地坑防水施工中多次采用刚性防水技术,这种防水技术具有良好的防水效果,且施工简便,造价经济,最大优点是当发生渗漏时便于修补。刚性防水指用水泥砂浆抹面防水,它是利用抹压密实的水泥素灰和水泥砂浆分层交替施工,使各层残留毛细孔互不贯通,因而
In industrial and civil buildings, small and medium-sized pit projects are often encountered. Such pit projects must be waterproofed. The commonly used coil waterproofing is leaked due to the construction quality and the coil layer is easily damaged during construction, etc. Repair is very difficult, and serious rework must be performed. Based on the above situation, we have adopted rigid waterproof technology in the waterproof construction of the pit for many times. This waterproof technology has good waterproof effect, and the construction is simple and economical. The biggest advantage is that it is easy to repair when leakage occurs. Rigid waterproof refers to the use of cement mortar to wipe waterproof, it is the use of pressure and compact cement ash and cement mortar layer alternate construction, so that each layer of residual pores do not penetrate each other.
