Vertical anti-seepage curtain connecting structure and construction method
The invention relates to a vertical anti-seepage curtain connecting structure which is characterized in that a TRD construction method cement-soil stirring wall is composed of an inner wall body, a middle wall body and an outer wall body, and the middle wall body shrinks inwards so that a bayonet can be formed between the inner wall body and the outer wall body; and the HDPE film of the HDPE film-bentonite composite diaphragm wall is laid in the bayonet and is connected with the middle-layer wall body. The method has the beneficial effects that for a refuse landfill with a complex stratum condition, a TRD construction method cement soil stirring wall is constructed in a non-inferior soil layer area, and a slotting construction mode is adopted in an inferior soil layer area to replace refuse soil, miscellaneous fill and the like in a forced examination range and construct an HDPE film-bentonite composite diaphragm wall; the TRD construction method cement soil stirring wall and the HDPE film-bentonite composite anti-seepage wall are applied to the complex stratum environment of the refuse landfill and are completely integrated, and the purpose of long-term vertical anti-seepage blocking of the refuse landfill is achieved under the condition that implementation reliability and economical efficiency are met.
本发明涉及一种垂直防渗帷幕连接结构，TRD工法水泥土搅拌墙由内、中、外三层墙体构成，且中层墙体内缩以使内、外墙体之间形成卡口；HDPE膜‑膨润土复合防渗墙的HDPE膜铺设至卡口内，并与中层墙体相连。有益效果为：对于地层情况复杂的垃圾填埋场，在非劣质土层区域施作TRD工法水泥土搅拌墙，而在劣质土层区域采取开槽施工方式将强审范围内的垃圾土、杂填土等进行置换并施作HDPE膜‑膨润土复合防渗墙，将TRD工法水泥土搅拌墙和HDPE膜‑膨润土复合防渗墙两种不同墙体应用在垃圾填埋场复杂地层环境中，并让两者完全形成一体，在满足实施可靠性和经济性的条件下，达到垃圾填埋场长久垂直防渗阻隔的目的。
