Problems solved by technology

[0002] At present, in the process of treating strong permeable dam foundations, anti-seepage methods such as concrete cut-off walls and high-pressure jet grouting piles are often used for reinforcement. In this way, concrete is injected into the dam foundation. During the construction process, groundwater is inevitably If different materials are used for anti-seepage treatment on the dam body and dam foundation, erosion will inevitably occur at the junction of the two materials, endangering the safety of the anti-seepage body and dam body

Embodiment 1

[0043] The dam foundation is partially depressed downwards to form a cut-off groove 10, and the anti-seepage structure includes an anti-seepage layer 20 covering at least part of the side wall of the dam body and an anti-seepage matrix filled in the cut-off groove 10, such as figure 1 shown.

[0044]The anti-seepage structure includes an anti-seepage layer 20 and an anti-seepage matrix. The dam foundation is partially recessed downward to form a water interception groove 10. By filling the anti-seepage matrix in the water interception groove 10, the water interception groove 10 has an anti-seepage function, and the effective wall surface Water infiltrates to the dam foundation, and by covering at least part of the side wall surface of the dam body with the anti-seepage layer 20, the dam body has an anti-seepage function, effectively preventing water from infiltrating the dam body, and improving the overall performance of the anti-seepage dam. security.

Embodiment 2

[0051] The difference from Embodiment 1 is that: on the basis of Embodiment 1, further, the anti-seepage embankment further includes: buttresses 40, which are arranged at the joint between the anti-seepage layer 20 and the anti-seepage matrix, and abut against the anti-seepage structure , used to fix the position of the anti-seepage structure shown, such as figure 1 shown.

[0052] The anti-seepage embankment also includes buttresses 40. By arranging the buttresses 40 at the junction of the anti-seepage layer 20 and the anti-seepage matrix, and abutting against the anti-seepage structure, the buttresses 40 play the role of fixing the anti-seepage structure, effectively It avoids the anti-seepage function of the dam body and dam foundation due to the anti-seepage structure being washed away or dispersed by water.

[0053] Preferably, the pier 40 is a concrete pier 40 .

[0054] The buttress 40 is a concrete buttress 40, and the strength of the concrete buttress 40 is higher, ...

Embodiment 3

[0061] The difference with Embodiment 1 or Embodiment 2 is: on the basis of Embodiment 1 or Embodiment 2, further, the anti-seepage dam also includes: a protective layer, laid on the part where the clay structure covers the side wall of the dam body on, such as figure 1 shown.

[0062] The anti-seepage dam also includes a protective layer. The protective layer is laid on the part of the clay structure covering the side wall of the dam body to protect the clay structure and prevent the part of the clay structure covering the side wall of the dam body from being damaged by water. Dispersed or collapsed, thereby further improving the anti-seepage effect of the clay structure on the anti-seepage dam.

[0063] Preferably, the protection layer includes a sandstone layer 301 laid on the part of the clay structure covering the side wall of the dam body and a concrete layer 302 poured on the sandstone layer 301 .

[0064] The protective layer includes a sandstone layer 301 and a conc...

Abstract

The invention provides an impermeable dam, which comprises a dam body and an impermeable structure. The dam body comprises a dam main body and a dam foundation connected with the bottom of the dam main body; and the impermeable structure covers at least part of the side wall face of the dam main body, and downwards extends to the bottom of the dam foundation, and the impermeable structure is of anintegrated structure. According to the impermeable dam, the impermeable structure covers at least part of the side wall face of the dam main body, and downwards extends to the bottom of the dam foundation, thus the dam main body and the dam foundation have impermeable functions, impermeability of the dam foundation and the dam main body is improved, and the situation that safety of the dam foundation and the dam main body is affected due to water permeation is prevented; the impermeable structure is of the integrated structure, thus through the integrated structure, the problem of contact flushing caused by the fact that impermeable structures of the dam foundation and the dam main body are made of different materials in the prior art can be effectively avoided, and the safety of the impermeable dam is effectively improved; and meanwhile, the impermeable dam is simple in structure and convenient to construct, and thus the construction cost of the impermeable dam is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of dam protection, in particular to an anti-seepage dam. Background technique [0002] At present, in the process of treating strong permeable dam foundations, anti-seepage methods such as concrete cut-off walls and high-pressure jet grouting piles are often used for reinforcement. In this way, concrete is injected into the dam foundation. During the construction process, groundwater is inevitably At the same time, if different materials are used for anti-seepage treatment of the dam body and dam foundation, the junction of the two materials will inevitably cause erosion, endangering the safety of the anti-seepage body and dam body. Contents of the invention [0003] In order to solve at least one of the above technical problems, the object of the present invention is to provide an anti-seepage dam. [0004] In order to achieve the above object, the technical solution of the present invention provides an ...
