Connection construction method for different anti-seepage barrier materials of polluted site
The invention provides a connection construction method for different anti-seepage barrier materials of a polluted site, which comprises the following steps of: dividing the polluted site into a key area and a non-key area according to an earlier-stage exploration design result, excavating slotted holes in the periphery of a wasteyard, paving an HPED geomembrane in the slotted holes covered by the key area, and constructing the different anti-seepage barrier materials of the polluted site. The GCL bentonite waterproof pads are laid in the slotted holes covering the non-key area, the HPED geomembranes are connected through locking openings, the GCL bentonite waterproof pads are in lap joint, the HPED geomembranes and the GCL bentonite waterproof pads are in lap joint, and special backfill materials are poured on the two sides of the lap joint section. The connecting structure of the HDPE geomembrane and the GCL bentonite waterproof pad is simple in structure, convenient to construct and effective, conditions are created for selecting different vertical barrier materials for a landfill according to geological conditions, hydrological conditions and on-site leakage conditions, and therefore conditions are created for saving engineering investment.
本发明提供了污染场地不同防渗阻隔材料的连接施工方法，包括根据前期勘探设计结果，将污染场地划分重点区域和非重点区域，并在垃圾场外围开挖槽孔，在重点区域覆盖的槽孔内铺设HPED土工膜，在非重点区域覆盖的槽孔内铺设GCL膨润土防水垫，HPED土工膜之间通过锁口连接，GCL膨润土防水垫之间搭接，HPED土工膜与GCL膨润土防水垫之间搭接并在搭接段的两侧浇筑特殊回填料。施工方便、有效的HDPE土工膜与GCL膨润土防水垫连接结构及施工方法，为填埋场根据地质条件、水文条件以及现场的渗漏情况，选择不同的垂直阻隔材料创造了条件，从而为节省工程投资创造了条件。
