Anti-seepage geomembrane cushion concrete backfilling structure
The invention provides an anti-seepage geomembrane cushion concrete backfill structure which comprises a foundation pit, a concrete backfill layer, a gravel layer, a backfill soil layer and a geomembrane are arranged in the foundation pit from bottom to top, an exhaust system is embedded in the gravel layer and comprises two main pipelines and a pipeline net, the two main pipelines are embedded in the two sides of the gravel layer, and the pipeline net is arranged between the two main pipelines. Each main pipeline is communicated with an exhaust channel, and the exhaust channels extend to the outer side of the foundation pit; the pipeline net is formed by transversely and longitudinally staggering a plurality of warp pipes and weft pipes, the warp pipes and the weft pipes are communicated with each other and are communicated with the main pipeline, and a plurality of air holes are formed in the warp pipes and the weft pipes. The structure has the beneficial effects that the exhaust system is arranged in the gravel layer, gas and water below the geomembrane are discharged out of the foundation pit, and the geomembrane is prevented from being damaged; the pipeline net in the exhaust system comprises the flexible joint, the flexible joint can flexibly connect the warp pipes and/or the weft pipes to form pipeline nets of different sizes, the pipeline nets are adaptive to foundation pits of different sizes, and the pipeline nets are flexible and convenient to assemble, disassemble and use.
本发明提供了一种防渗土工膜垫层混凝土回填结构，包括基坑，在基坑内由下向上地设有混凝土回填层、砂石层、回填土层和土工膜，砂石层内埋设有排气系统，排气系统包括两根主管道以及管道网，两根主管道埋设在砂石层的两侧，每根主管道与一排气通道相连通，排气通道延伸至基坑外侧；管道网由多根经管和纬管横纵交错形成，经管和纬管相互连通，且与主管道相连通，经管和纬管上均设有多个气孔。本发明的有益之处在于，通过在砂石层中设置排气系统，将土工膜下的气体和水分排至基坑外，防止土工膜受损；排气系统中的管道网包括柔性接头，柔性接头可以将经管和/或纬管柔性连接，形成不同大小的管道网，适配不同尺寸的基坑，装卸使用灵活方便。
