Problems solved by technology

[0002] During the construction of earth-rock dams, often due to the construction of vertical anti-seepage bodies such as foundation concrete cut-off walls and curtain grouting, it is necessary to occupy the dam body filling face, resulting in the anti-seepage body becoming the key line of construction, resulting in long construction periods and poor water supply. , The power generation node time is late, which is not conducive to saving project investment

Abstract

The invention belongs to the field of civil engineering, and discloses an earth and rockfill dam foundation anti-seepage body construction pipe gallery and a use method thereof. According to the technical scheme, the pipe gallery is arranged between a first-built dam body and a second-built dam body, a construction space and a material conveying channel of an earth and rockfill dam foundation anti-seepage body are formed in a pipe gallery body, a grouting opening is formed in the bottom of the pipe gallery, and an anti-seepage body material is poured downwards through the grouting opening to form the earth and rockfill dam foundation anti-seepage body. An anti-seepage body construction mechanical equipment arrangement space and the material conveying channel are formed in an earth and rockfill dam, and dam earth and rockfill filling construction can be carried out at the same time during construction of the earth and rockfill dam foundation anti-seepage body. Dam body earth and rockfill filling and anti-seepage body construction can be synchronously carried out, and the construction period of a key line can be shortened. Waste water and waste liquid generated during construction can be treated and discharged in a centralized manner, and construction noise in a closed space is controllable. Interference of weather conditions to the anti-seepage body construction period is small, and continuous construction is facilitated.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a construction pipe gallery of an anti-seepage body for an earth-rock dam foundation and a method for using the same. Background technique [0002] During the construction of earth-rock dams, often due to the construction of vertical anti-seepage bodies such as foundation concrete cut-off walls and curtain grouting, it is necessary to occupy the dam body filling face, resulting in the anti-seepage body becoming the key line of construction, resulting in long construction periods and poor water supply. , The power generation node time is late, which is not conducive to saving project investment. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a construction pipe gallery for an anti-seepage body of an earth-rock dam foundation and a method for using the same. Inside the earth-rock dam, a space for the ar...
