当今建筑施工行业迅猛发展,高大、超高建筑物越来越多,对地基的要求也越来越高,而桩基础底板桩头防水一直是施工的难点和薄弱环节。一、一般做法(1)在桩顶、外露桩身及其周边垫层表面涂刷水泥基渗透结晶型防水涂料。(2)在水泥基渗透结晶型防水涂料表面铺设聚合物水泥防水砂浆。(3)在桩身周边聚合物水泥防水砂浆表面铺贴防水卷材。(4)在防水卷材表面铺设水泥砂浆或
Nowadays, the construction industry is developing rapidly. More and more tall and ultra-high buildings are required, and the requirements for the foundation are getting higher and higher. The waterproofing of the pile foundation of the pile foundation has always been a difficult and weak point in the construction. First, the general approach (1) in the top of the pile, exposed pile body and its surrounding padded brushing cementitious capillary crystalline waterproof coating. (2) The polymer cement waterproof mortar is laid on the surface of cementitious capillary crystalline waterproof coating. (3) Surrounding the pile of polymer cement waterproof mortar surface waterproofing membrane. (4) laying waterproofing membrane surface or mortar
