| description | 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 fro |
