Hydropower station dam body leaking stoppage construction method
The invention discloses a hydropower station dam body leaking stoppage construction method which comprises the following steps that a dam body is drilled, a water seepage channel is determined, and a communicating hole is formed; the drilled hole diameter, distance and depth are checked, the upper and lower separation space distance of the water seepage channel is determined, and the water seepage channel is checked; performing reaming operation on the drilled hole for concrete pouring construction; after reaming, water injection operation is carried out, then mortar pouring is carried out, first-level concrete is poured into a hole for pouring, quick-setting concrete is poured into the hole for pouring, and finally common grout concrete is used for pouring construction. According to the scheme, a multi-hole and multi-material combined large-flow pouring construction mode is adopted, and a synchronous concrete pouring mode is matched with cement water glass and polyurethane pouring when the water level in front of the dam is low, so that a large amount of loss of cement or polyurethane slurry is weakened, leakage stopping treatment can be effectively conducted on leakage points, and the leakage stopping effect is good. And in the grouting process, cementing materials cannot be lost along with water burst, materials are saved, and construction is easy.
本发明公开了一种水电站坝体堵漏施工方法，包括如下步骤：对坝体进行钻孔，确定渗水通道，形成连通孔；钻完的孔径、间距、深度进行检查，确定渗水通道上下脱空间距，并对渗水通道进行检查；对钻孔进行扩孔操作，用于混凝土灌注施工；在扩孔之后，进行注水操作，然后进行砂浆灌注，再向孔内注入一级混凝土进行灌注，再向孔内注入速凝混凝土进行灌注，最后使用普通浆液混凝土进行灌注施工。本方案采用多孔、多材料联合大流量灌注的施工方式，并在坝前低水位时利用同步灌注混凝土方式配合水泥水玻璃和聚氨酯灌注，减弱水泥或聚氨酯浆液大量流失，可以有效对渗漏点进行堵漏处理，且灌浆过程中胶凝材料不会随着涌水流失，节省材料，施工简单。
