Anti-seepage and anti-corrosion construction method for concrete dam
The invention discloses an anti-seepage and anti-corrosion construction method for a concrete dam, which comprises the following steps of: (1) treating a dam foundation, (2) installing upstream and downstream templates of the dam, and (3) pouring concrete, and a concrete spraying machine is adopted to spray a layer of concrete added with an anti-seepage and anti-corrosion material to form an anti-seepage and anti-corrosion layer, then dam concrete is backfilled to be rolled and vibrated, the dam concrete and the anti-seepage and anti-corrosion layer are integrated, and construction is completed. According to the anti-seepage and anti-corrosion construction method of the concrete dam, a layer of anti-seepage or anti-corrosion concrete is sprayed on the inner surface of the formwork to form an anti-seepage layer or an anti-corrosion layer, the anti-seepage layer or the anti-corrosion layer and dam concrete are constructed at the same time to form a whole, the combination quality is high, the construction technology is greatly simplified, the construction progress is accelerated, the construction period is shortened, and investment is saved.
本发明公开了一种混凝土大坝的防渗抗腐蚀施工方法，包括①坝基处理②安装大坝上下游模板③浇筑混凝土：当大坝碾压混凝土碾压或振捣至上游模板附近时，在模板内表面，采用混凝土喷射机喷涂一层添加有抗渗防腐材料的混凝土形成防渗抗腐蚀层，之后回填大坝混凝土碾压振捣，使之形成一体，完成施工。本发明提供的混凝土大坝的防渗抗腐蚀施工方法，通过在模板内表面喷射一层抗渗或抗腐蚀混凝土，形成防渗层或抗腐蚀层，与大坝混凝土同时施工形成整体，结合质量高，大大简化了施工工艺，加快了施工进度，缩短了工期，节约了投资。
