Abstract

The invention discloses an anti-seepage structure for an earth-rock dam. The anti-seepage structure is arranged on a side surface of a earth-rock dam body and comprises a lower cushion layer, an anti-seepage film layer, an inverted filter transition layer and a protective slope which are sequentially arranged from top to bottom; the lower cushion layer is made of sieved silt sand with the thickness of 5-10cm and/or fine-grained sandy clay; the anti-seepage film layer is made of anti-seepage materials and is used for preventing water from seeping into the earth-rock dam body; the inverted filter transition layer is made of sand gravel with the thickness of 10-20cm and/or rubble. The anti-seepage structure for the earth-rock dam has the advantages that an obvious anti-seepage effect can be realized for the dam by the anti-seepage structure, and the anti-seepage structure is convenient to construct, short in construction period, simple in operation, long in service life and low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of earth-rock dams, in particular to an anti-seepage structure of earth-rock dams. Background technique [0002] Earth-rock dams generally refer to retaining dams made of local soil, stone or mixed materials, which are piled up by throwing filling, rolling and other methods. In the early days, due to limited technical and financial reasons, clay grouting anti-seepage structure has always been the main measure for dam anti-seepage treatment. The functions of the clay grouting anti-seepage structure are as follows: a. During the grouting process, due to the specific gravity of the mud and the extrusion of the dam body by the outside world, when the small principal stress of the dam body is less than the grouting pressure of the mud, the dam body will be split and the mud will Going deep into the cracks, the grout and the crack wall are closely combined to form an anti-seepage curtain; b. Clay slurry can fill the gaps o...
