Embodiment Construction

[0013] Such as figure 1 Shown is a retaining dam for water conservancy and hydropower projects with simple structure, convenient construction and low investment cost provided by the present invention. The retaining dam includes a transition cushion material 1, a reverse filter material layer 2 and a gravel layer 3, and also includes an anti-seepage core wall 4 made of geomembrane, and the anti-seepage core wall 4 is located at the retaining dam 5 The transverse middle part of the water retaining dam 5 extends longitudinally and vertically; direction and downstream direction are arranged sequentially. Due to the vertical anti-seepage treatment of the retaining dam 5 described in the application, the anti-seepage wall and / or grouting curtain of the existing concrete structure are replaced by the anti-seepage core wall 4 of the geomembrane structure, and at the same time, because the structure adopts At present, the existing shaped geomembrane material can be directly and conve...

Abstract

The invention discloses a retaining dam, particularly discloses the retaining dam for hydraulic and hydro-power engineering and belongs to the technical field of design and construction of hydraulic and hydro-power engineering buildings. The retaining dam for the hydraulic and hydro-power engineering is simple in structure, convenient to construct and low in investment cost. The retaining dam comprises a transitional cushion material, an inverted filter layer, a rock ballast layer and an anti-seeping core wall composed of geomembranes, wherein the anti-seeping core wall is located in the middle of the retaining dam transversely and extends along the retaining dam longitudinally and vertically; the transitional cushion material, the inverted filter layer and the rock ballast layer are sequentially arranged in upstream and downstream directions of the anti-seeping core wall.

Description

technical field [0001] The invention relates to a water retaining dam, in particular to a water retaining dam used in water conservancy and hydropower projects, and belongs to the technical field of design and construction of buildings in water conservancy and hydropower projects. Background technique [0002] At present, in the construction of hydropower and water conservancy projects, especially in the construction of hydropower and water conservancy projects in alpine and valley areas, the available construction sites on site are very limited. Therefore, the gullies or small rivers around the project are often used to arrange various construction auxiliary facilities such as slag yards, processing plants, and camps, which requires engineering treatment measures for gully water. Ditch water treatment projects are usually composed of retaining dams and drainage structures, and are generally small in scale. If the retaining dam is arranged on a gully with deep overburden, i...
