隧道工程中的混凝土三缝即施工缝、变形缝(包括伸缩缝和沉降缝)、裂缝漏水和建筑工程中的屋面、卫生间及地下室等地下工程漏水一样都是建设工程的通病。有的工程即使大面积防水做得很好,但接缝如漏水,整个建筑物的使用同样受到影响,漏水严重者将使建筑物的某一部分(如地下室等)无法使用。因此,防水技术工作者不仅要解决大面积的防水技术问题,包括防水材
Tunnel construction of the three joints that is, construction joints, deformation joints (including expansion joints and settlement joints), crack leakage and construction of the roof, bathroom and basement and other underground works are the same as the common fault of construction projects. Even if a large area of waterproof works well, seams such as water leakage will affect the whole building. If a serious water leakage occurs, a part of the building, such as a basement, can not be used. Therefore, waterproofing technology workers not only to solve a large area of waterproof technology issues, including waterproof material
