Use method of geomembrane in reservoir bottom seepage prevention and whole reservoir basin membrane seepage prevention system
The invention discloses a use method of a geomembrane in reservoir bottom seepage prevention and a whole reservoir basin membrane seepage prevention system, and belongs to the technical field of geomembranes. A use method of geomembranes in reservoir bottom seepage prevention comprises the steps that 1 # TPO geomembranes are laid in a reservoir bottom filling area, HDPE geomembranes are laid in an excavation area, transition membranes are laid at drainage galleries, and then the geomembranes laid in all the areas are firmly pressed through sandbags; the transition membrane is connected with the 1 # TPO geomembrane and the HDPE geomembrane in a welded mode, then the sandbag is moved away, and the geomembranes in all the areas are covered with concrete or compacted with clay; wherein the transition membrane is formed by welding a 2 # TPO geomembrane and a novel geomembrane, one end, far away from the novel geomembrane, of the 2 # TPO geomembrane is connected with the 1 # TPO geomembrane, and one end, far away from the 2 # TPO geomembrane, of the novel geomembrane is connected with the HDPE geomembrane. Effective connection between two different types of geomembranes of HDPE and TPO is achieved, and concentrated leakage of a reservoir bottom membrane anti-seepage structure caused by the clamp effect is avoided.
本申请公开了一种土工膜在库底防渗中的使用方法及全库盆膜防渗系统，属于土工膜技术领域。一种土工膜在库底防渗中的使用方法，包括：在库底填方区铺设1#TPO土工膜，挖方区铺设HDPE土工膜，排水廊道处铺设过渡膜，然后通过沙袋将各个区域铺设的土工膜压牢；将过渡膜分别与1#TPO土工膜和HDPE土工膜进行焊接连接，然后移开沙袋，并在各个区域的土工膜上覆盖砼或压实粘土；其中，过渡膜由2#TPO土工膜和新型土工膜焊接而成，2#TPO土工膜远离新型土工膜的一端与1#TPO土工膜相连，新型土工膜远离2#TPO土工膜的一端与HDPE土工膜相连。实现了HDPE和TPO两种不同类型土工膜之间的有效连接，避免因“夹具效应”导致库底膜防渗结构出现集中渗漏。
