AI Technical Summary
Technical Problem
In existing water conservancy projects, the water-facing side of earth-rock cofferdams is prone to seepage and instability due to repeated scouring by water flow, affecting the overall stability.
Method used
An anti-seepage wall is inserted into the main body of the cofferdam, and an anti-scouring retaining wall is set on the water-facing slope. Combined with an anti-seepage geomembrane and a concrete finishing layer, the seepage prevention capacity is enhanced and the scouring damage is reduced.
Benefits of technology
It effectively prevents water seepage, reduces erosion damage to the water-facing slope, improves the overall stability of the cofferdam, and avoids collapse.

Abstract
The utility model discloses an anti-seepage cofferdam of a reservoir, and relates to the technical field of cofferdam construction, the anti-seepage cofferdam of the reservoir comprises a cofferdam body arranged above a riverbed, the two sides of the cofferdam body are provided with an upstream slope and a downstream slope respectively, one side of the upstream slope is provided with an anti-scouring retaining wall, and the anti-scouring retaining wall extends upwards along the upstream slope; an anti-seepage wall inserted into a riverbed is arranged in the cofferdam body, the anti-seepage wall is flush with the top of the cofferdam body, and the anti-seepage wall is arranged in the length direction of the cofferdam body. The anti-seepage wall is inserted into a riverbed in the height direction of the cofferdam body, and water seepage of the upstream slope of the cofferdam body is prevented from permeating the cofferdam body as much as possible; the anti-scouring retaining wall is arranged on the upstream slope of the cofferdam main body, the anti-scouring retaining wall is a slope protection composed of a reinforcement cage and gravel blocks, and the situation that the upstream slope of the cofferdam main body is scoured to cause soil loss, stability of the cofferdam main body is lowered, and collapse is caused is avoided as much as possible.
