Sludge geology geomembrane anti-seepage system and construction method thereof
The invention provides a silt geology geomembrane anti-seepage system which comprises a light cushion layer arranged above silt, a GCL bentonite waterproof blanket and an HDPE anti-seepage geomembrane are arranged above the light cushion layer, and a pressing device used for pressing and fixing the HDPE anti-seepage geomembrane is arranged above the HDPE anti-seepage geomembrane. A geotechnical cloth protection layer and an air guide pumping and discharging device used for maintaining negative pressure below the HDPE anti-seepage geomembrane are arranged above the water level infiltration area above the HDPE anti-seepage geomembrane, and the GCL geosynthetic clay liner and the HDPE anti-seepage geomembrane are fixed through an anti-seepage system fixing device. Belongs to the technical field of geomembrane seepage prevention. According to the silt geology geomembrane anti-seepage system and the construction method thereof, the problem that a traditional anti-seepage system design is difficult to apply under the silt geology condition is effectively solved, it is not needed to spend a large amount of cost for basic treatment, and the problem that the reliability of the anti-seepage system is insufficient due to the fact that no drainage and exhaust layer exists under the membrane is solved.
本发明提供了一种淤泥地质土工膜防渗系统，包括设于淤泥上方的轻质垫层，轻质垫层上方设有GCL膨润土防水毯及HDPE防渗土工膜，HDPE防渗土工膜上方设有用于压覆固定HDPE防渗土工膜的压覆装置，HDPE防渗土工膜上方水位浸润区以上设有土工布保护层及用于维持HDPE防渗土工膜下负压的导气抽排装置，GCL膨润土防水毯及HDPE防渗土工膜通过防渗系统固定装置固定。属于土工膜防渗技术领域。本发明的淤泥地质土工膜防渗系统及其施工方法，有效解决传统传统防渗系统设计在淤泥地质条件下应用的难题，无需花费大量费用进行基础处理，解决膜下无排水排气层造成的防渗系统可靠性不足的问题。
