混凝土结构的背水面防水处理技术

Waterproofing Technology in the Water Opposite Side of Water Retaining Concrete Structure

介绍了混凝土结构、砖石砌体结构的背水面防水、防潮处理技术。就地下构筑物而言,背水面防水是指在构筑物内表面设计、施工防水屏障。对贮水池结构来说,采用背水面防水,则意味着防水层在结构的外表面。一般来说,背水面防水处理,不如迎水面的有利,但它施工方便、操作安全,并可多种材料比选和采用不同的作法。在新的建筑中可以设计采用,如贮水池、输水管渠,以及在结构迎水面无法设置防水层的地下工程。但背水面防水做法最适用于维修工程,如地铁车站和区间隧道,以及其他地下结构等的裂缝修补。

This paper expounds the waterproofing and moistureproofing technology of the opposite side of water retaining concrete structure and masonry structure. General speaking, water opposite side waterproofing is less beneficial than water facing side waterproofing, but it can be executed conveniently, operated safely with various material and different construc-tion methods. The water opposite side waterproofing method can be used in the under con-struction engingeering, but it is most suitable for maintenance engineering.
