Double-layer geomembrane anti-seepage structure and inflation inspection method thereof
The invention belongs to the technical field of water conservancy and hydropower engineering, and discloses a double-layer geomembrane anti-seepage structure and an inflation inspection method thereof, the double-layer geomembrane anti-seepage structure adopts an upper-layer geomembrane anti-seepage structure and a lower-layer geomembrane anti-seepage structure, the integrity guarantee rate of the double-layer geomembrane anti-seepage structure is higher than that of a single-layer geomembrane, and a continuous closed partition with the side length not larger than 2 m is formed through hot melting or bonding. The pipe-film integrated components are arranged at the four corners of each closed subarea, the integrity and sealing performance of each closed subarea can be inspected by inflating along the inflating grouting pipes, inspection is carried out before and after filling of a protective layer, the sealing performance can be inspected more reliably, and the sealing performance of each closed subarea is guaranteed. Grouting repair is carried out on the defective closed subareas through grouting along the inflatable grouting pipes, the anti-seepage closing effect is ensured, the reliability is high, construction is easy and convenient, and the inspection and test cost is low.
本发明属于水利水电工程技术领域，公开一种双层土工膜防渗结构及其充气检查方法，采用上下两层土工膜的防渗结构，较单层土工膜的完整保证率提高，并通过热熔或粘结形成边长不大于2m的连续封闭分区，在每个封闭分区四角设置管膜一体化构件，通过沿充气灌浆管充气可实现对每个封闭分区的完整性、封闭性检查，分别在保护层填筑前后开展检查，能更加可靠的对封闭性进行检查，并通过沿充气灌浆管灌浆对有缺陷封闭分区进行灌浆修补，确保防渗封闭效果，可靠性高、施工简便、检查试验成本低。
