人防及地下室工程渗水漏水,将给工程使用带来很多困难。为解决这一问题,几年来,我们曾试用氰凝防水剂、有机硅五层涂刷做法、有机硅防水砂浆等方法,在防渗堵漏方面取得了初步效果,现将其做法简介如下。一、氰凝防水剂施工 1.材料所用材料有氰凝预聚体TT-1、TP-2,增塑剂邻苯二甲酸二丁酯,溶剂丙酮,表面活性剂吐温-80,催化剂三乙胺及矿渣水泥。 2.氰凝防水剂施工 (1)涂刷当地下室墙壁表面呈现潮湿,但无明水时,可采用涂刷方法进行防潮处理。防潮浆液配合比(重
Civil air defense and leaking water in the basement project will bring a lot of difficulties to the project. In order to solve this problem, in the past few years, we have tried cyanide waterproofing agents, organosilicon five-layer brushing practices, and silicone waterproof mortars, and achieved initial results in the prevention of seepage and plugging. The current practice is described below. First, cyanide waterproofing agent construction 1. Materials used are cyanide prepolymer TT-1, TP-2, plasticizer dibutyl phthalate, solvent acetone, surfactant Tween-80, catalyst three Ethylamine and slag cement. 2. The construction of cyanide waterproofing agent (1) The surface of the wall of the local lower chamber is damp, but when there is no clear water, the dampening method can be applied.
