Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] like Figure 1 to Figure 6 As shown in , the layered composite material for dam seepage prevention according to the present invention, the layered composite material includes at least one skeleton layer 1 and at least one filler layer 2, and the skeleton layer 1 and filler layer 2 are sequentially Arranged at intervals; the skeleton layer 1 is a layer of flexible layer laid by chemical fiber net, and the filler layer 2 is a layer of flexible layer laid by asphalt or clay or gravel soil or polyurethane or epoxy resin. Layer; when filler layers 2 are respectively arranged on both sides of the same skeleton layer 1, the filler layers 2 on both sides of the skeleton layer 1 are connected to each other through the hollow grid 3 on the chemical fiber net that forms the skeleton layer 1.

[0036] Among them, the skeleton layer 1 and the filler...

Abstract

The invention discloses a laminar composite for dam body seepage prevention, a dam body seepage structure and a construction method thereof, belongs to the field of water conservancy and hydropower engineering, and provides a laminar composite for dam body seepage prevention and a dam body seepage prevention structure. The problem that the seepage prevention structure deforms along with the dam body and is cracked can be solved, and then the seepage prevention effect of a dam is ensured. By adopting the mode that a flexible skeleton layer and a flexible packing layer are arranged in an interlayered mode, when used for dam seepage prevention, the laminar composite can deform along with the deformation of the dam, and the problem that the seepage prevention body is cracked can be effectively avoided, so that the seepage prevention effect of the dam can be ensured. The laminar composite can also be produced in batches in a factory, so that the dam seepage prevention construction efficiency can be effectively improved, and the construction cost can be lowered. In addition, the laminar composite and the dam material have the good interconnectivity, and the layering phenomenon can be effectively avoided; the material can also be used for a seepage prevention structure for concrete surface crack repairing.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering, in particular to the technical field of anti-seepage of dam bodies in water conservancy and hydropower projects, in particular to a layered composite material for dam anti-seepage, a dam anti-seepage structure and a construction method thereof. Background technique [0002] In the prior art, the anti-seepage structure or anti-seepage layer structure of the dam mainly includes reinforced concrete, clay, asphalt concrete, steel, etc., and the disadvantage of the above-mentioned anti-seepage structures is that it is difficult to adapt to the anti-seepage support body. Or the larger deformation of the dam body itself. Especially for the increasing number of rockfill dams with a height greater than 200m or even greater than 300m in recent years or high dams built on ultra-deep overburden, the deformation of each part of the dam body is often large in the later stage; therefo...
