Geomembrane anti-seepage blanket exhaust structure and method
The invention relates to a geomembrane anti-seepage blanket exhaust structure and method.The geomembrane anti-seepage blanket exhaust structure comprises a geomembrane anti-seepage area, an exhaust valve, an air pressure monitoring valve and hot melt adhesive filler, the surface of the geomembrane anti-seepage area is covered with a geomembrane, and the geomembrane anti-seepage area is provided with a plurality of divided blocks; the exhaust valves are arranged in at least part of the blocks, and the exhaust valves are used for being connected with a vacuum pump so as to perform under-membrane air exhaust on the geomembranes of the blocks; the air pressure monitoring valve is arranged at the joint part of at least part of the blocks and is used for being connected with a pressure gauge to monitor the air pressure under the film; after the under-membrane air pressure of the geomembrane is lower than a preset value, the exhaust valve and the air pressure monitoring valve are blocked by the hot melt adhesive filler, in addition, a water soaking structure is arranged on the covering periphery of the geomembrane seepage-proofing area, and the water soaking structure is used for preventing air leakage of the periphery of the geomembrane seepage-proofing area along cracks in the air exhaust process; according to the exhaust structure of the geomembrane anti-seepage blanket, the operation safety of the geomembrane anti-seepage blanket can be improved.
本申请涉及一种土工膜防渗铺盖排气结构与方法，该土工膜防渗铺盖排气结构包括土工膜防渗区、排气阀、气压监测阀和热熔胶填料，土工膜防渗区的表面覆盖有土工膜，且土工膜防渗区具有划分布置的多个区块；排气阀设置于至少部分区块中，排气阀用于连接真空泵以对区块的土工膜进行膜下抽气；气压监测阀设置于至少部分区块的交接部位，气压监测阀用于连接压力表以进行膜下气压的监测；在土工膜的膜下气压低于预设值后，热熔胶填料封堵于排气阀和气压监测阀，另外，土工膜防渗区的覆盖周边设置有浸水结构，浸水结构用于防止抽气过程中土工膜防渗区的周边沿裂隙漏气；该土工膜防渗铺盖排气结构能够提高土工膜防渗铺盖运行安全。
