Anti-seepage structure capable of adapting to settlement of earth and rockfill dam

Abstract

Provided is an anti-seepage structure capable of adapting to settlement of an earth and rockfill dam. The anti-seepage structure is technically characterized in that a concrete anti-seepage wall is arranged below a dam foundation; an asphalt concrete core wall is arranged inside the rockfill dam; an arched anti-seepage wall connecting section is arranged between the concrete anti-seepage wall and the asphalt concrete core wall, wherein the top of the concrete anti-seepage wall is embedded in an arched entrance of the arched anti-seepage wall connecting section, and the bottom of the asphalt concrete core wall is arranged at the arched top end of the arched anti-seepage wall connecting section; the two sides of the asphalt concrete core wall are filled with sand gravel transition materials; and the inner side of the arched anti-seepage wall connecting section is further filled with flexible anti-seepage body materials. Due to the adoption of the arched anti-seepage wall connecting section, the foundation anti-seepage wall is allowed to penetrate into the connecting section in the filling process of the earth and rockfill dam, and the connecting section is filled with the flexible anti-seepage materials after primary settlement of the earth and rockfill dam and the foundation is basically completed. Meanwhile, according to the structure, a worker can enter the connecting section for observation and inspection at any time in the construction process or in the later period.

Description

technical field [0001] The invention relates to the technical field of anti-seepage connection between a core wall of an earth-rock dam and a foundation of a reservoir pivotal project, in particular to an anti-seepage structure adapted to the settlement of an earth-rock dam. Background technique [0002] As we all know, the construction of reservoirs for the comprehensive utilization of water resources refers to artificial lakes formed by building barrages at the narrow mouths of ravines or rivers. After the reservoir is completed, it can play the role of flood control, water storage for irrigation, water supply, power generation, fish farming, etc., thus bringing positive impacts on the industrial and agricultural production and people's life and health around the reservoir. important aspects. It mainly includes three main aspects of dam body anti-seepage, foundation anti-seepage and connection of two anti-seepage bodies. [0003] In the anti-seepage problem, the connecti...

Problems solved by technology

In particular, the rigid anti-seepage wall built in the deep covering layer will not deform with the foundation during the filling process of the earth-rock dam, forming a deformation difference beyond the contact surface between the dam body and the original ground, causing damage to the anti-seepage structure built on it, and reaching the reservoir Seepage prevention failure, resulting in irreparable loss of life and property
