Asphalt concrete panel-geomembrane anti-seepage system and construction method thereof

Abstract

The invention provides an asphalt concrete panel-geomembrane anti-seepage system. The asphalt concrete panel-geomembrane anti-seepage system comprises an asphalt concrete panel, a geomembrane, an anti-seepage cover sheet and an edge sealing agent; the geomembrane covers the asphalt concrete panel and is directly connected with the asphalt concrete panel in an anchoring mode; and the anti-seepage cover sheet covers the anchoring connecting position and the upper part of the geomembrane on the periphery of the anchoring connecting position, and the edge of the anti-seepage cover sheet is connected with the asphalt concrete panel through the edge sealing agent. The invention further provides a construction method of the anti-seepage system. According to the technical scheme, the connecting anti-seepage structure is simplified, and the problems that in a traditional concrete connecting plate, geomembrane and asphalt concrete anti-seepage connecting system, due to the fact that the material rigidity difference is large, the adaptive deformation capacity is poor, the safety and reliability are poor, and the construction quality is difficult to guarantee are solved.

Description

technical field [0001] The invention relates to a connection anti-seepage structure and a construction method of asphalt concrete and geomembrane. Background technique [0002] In water conservancy and hydropower projects, geomembrane and asphalt concrete are efficient and environmentally friendly anti-seepage materials, and are widely used in anti-seepage projects such as reservoirs and dams. Geomembrane has excellent anti-seepage performance, high tensile strength, strong adaptability to deformation, good corrosion resistance, and low engineering cost; asphalt concrete has good anti-seepage performance, good integrity and no joints, high construction mechanization efficiency, Easy maintenance and other features. However, due to the low strength of asphalt concrete, it is difficult to directly anchor anti-seepage bodies such as geomembranes to asphalt concrete panels through large mechanical anchoring forces. When two or more anti-seepage types are used for the reservoir ...

AI Technical Summary

Problems solved by technology

This approach has the following problems: (1) Poor ability to adapt to deformation

Since the geomembrane and the asphalt concrete panel are respectively connected with the concrete connection plate, the rigidity of these three materials is greatly different, so the connection structure has poor adaptability to deformation

(2) poor safety and reliability

Geomembrane, asphalt concrete panel, and concrete connecting plate are three different materials with complex structural connections. In the case of frequent changes in the water level of the reservoir, the reliability of the anti-seepage structure is poor, and problems such as leakage are prone to occur

(3) Construction quality is difficult to guarantee

Since the construction process of connecting the concrete connecting plate with the geomembrane and asphalt concrete is relatively complicated, mutual interference is easily formed during the construction process, so its quality is difficult to effectively guarantee
