Description

Technical Field

[0001] The utility model relates to the field of water conservancy and hydropower engineering, and particularly relates to a connecting structure between a reinforced concrete impervious panel and a geomembrane. Background Technique

[0002] With the rapid development of water conservancy and hydropower engineering construction, certain anti-seepage measures need to be taken for some reservoir basins to avoid large-scale leakage problems. As an anti-seepage structure, the reinforced concrete panel can be arranged on the bedrock, with good anti-seepage conditions and convenient construction. For reservoirs with good bedrock, reinforced concrete impervious panels are often used to prevent water in the reservoir from leaking. The geomembrane anti-seepage material has the characteristics of good flexibility and strong adaptability to deformation, and has wide applicability in areas with poor foundation geological conditions of the reservoir basin or filled areas. For semi-excavated and semi-filled reservoir basins, the above two anti-seepage materials need to be used simultaneously to ensure the anti-seepage quality of the reservoir basin. In order to ensure that the reservoir does not leak, what type of connection between the reinforced concrete impervious panel and the geomembrane is adopted, especially the connection at the position where the geomembrane crosses the structural joint of the reinforced concrete panel, has become a major difficulty for design engineers. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a connecting structure between a reinforced concrete impervious panel and a geomembrane. The connecting structure of the utility model has the advantages of simple structure and convenient construction, and has a remarkable anti-seepage effect. The geomembrane can be connected with the reinforced concrete impervious panel to form an anti-seepage whole.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] A connecting structure between a reinforced concrete impervious panel and a water intake, characterized in that: it includes a reinforced concrete impervious panel structure, a geomembrane, an anchoring structure, and a structural joint. A cushion material, fine sand and a composite drainage net are laid under the geomembrane to ensure the drainage capacity under the geomembrane. The geomembrane is bolted to the reinforced concrete panel, and the composite drainage net is cemented to the reinforced concrete impervious panel to form an anchoring structure.

[0006] Furthermore: the reinforced concrete impervious panel structure includes a reinforced concrete impervious panel, non-sand concrete and polyurea; the polyurea is located on the outermost layer of the reinforced concrete impervious panel structure, on the surface of the reinforced concrete impervious panel; the non-sand concrete is located on the innermost layer of the reinforced concrete impervious panel structure; below the reinforced concrete impervious panel; the reinforced concrete impervious panel is processed with a rounded edge on the side close to the geomembrane.

[0007] Furthermore, the anchoring structure includes bolts, flat steel straps, edge-sealing glue, and SR anti-seepage rubber strips; the SR anti-seepage rubber strips are located at the bottom layer of the anchoring structure, below the geomembrane; the SR protection cover is located at the middle layer of the anchoring structure, above the geomembrane; the edge-sealing glue is applied to both ends of the SR protection cover; the flat steel straps are located at the top layer of the anchoring structure; holes are drilled in the flat steel straps, bolts are arranged, and they are anchored into the reinforced concrete anti-seepage panel.

[0008] Furthermore, the structural joints of the reinforced concrete panel include bolts, flat steel straps, edge-sealing glue, SR filling material, SR protection cover, copper waterstop, and anchoring pits; the copper waterstop is located inside the structural joints of the reinforced concrete panel, arranged horizontally and vertically near the anchoring structure; the anchoring pits are located at the ends of the structural joints of the reinforced concrete panel, and the copper waterstop is embedded in them and sealed with slightly expanding concrete; the SR filling material is located in the V-shaped groove at the top of the structural joints of the reinforced concrete panel; the SR protection cover is arranged on the surface of the SR filling material; the flat steel straps are located at the two side edges of the SR protection cover; holes are drilled in the flat steel straps, bolts are arranged, and they are anchored into the reinforced concrete anti-seepage panel.

[0009] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0010] (1) The contact position between the reinforced concrete anti-seepage panel and the geomembrane is treated with a rounded edge, which can effectively avoid the risk of the geomembrane being punctured by the panel edge during construction and operation due to deformation.

[0011] (2) A vertical copper waterstop is arranged near the anchoring structure inside the structural joints of the reinforced concrete panel. When the anti-seepage on the surface of the structural joints fails, it can also serve as a water-blocking structure to prevent a large amount of reservoir water from leaking along the structural joints of the panel to the lower part of the geomembrane.

[0012] The present utility model is used to solve the connection problem between the reinforced concrete anti-seepage panel and the geomembrane of the reservoir basin, effectively forming an anti-seepage whole of the two anti-seepage materials, and further reducing the risk of reservoir leakage.
