Closure structure of rigid landfill and construction method
The invention discloses a closure structure of a rigid landfill and a construction method, the rigid landfill comprises a plurality of landfill units, and each landfill unit is filled with a landfill pile body. The closure structure comprises a flexible anti-seepage structure, a middle drainage layer and a rigid anti-seepage structure which are sequentially arranged on a landfill pile body. The flexible anti-seepage structure comprises an under-membrane protection layer and a sealing anti-seepage layer which are sequentially arranged from bottom to top, the under-membrane protection layer is connected with the side wall protection layer of the landfill unit, and the sealing anti-seepage layer is connected with the side wall anti-seepage layer of the landfill unit. The mode that the rigid anti-seepage structure and the flexible anti-seepage structure are combined is adopted, the requirement for a rigid landfill closure structure in the new standard can be met, and meanwhile rainwater permeating into top concrete can be collected, guided and drained. The problem of instability of a top concrete structure caused by heap settlement is avoided, and the long-term stability of the closure structure is improved.
本发明公开了一种刚性填埋场的封场结构及施工方法，刚性填埋场包括多个填埋单元，每个填埋单元内填充有填埋堆体；封场结构包括：在填埋堆体上依次设置的柔性防渗结构、中间排水层和刚性防渗结构；柔性防渗结构包括自下至上依次设置的膜下保护层和封场防渗层，膜下保护层与填埋单元的侧壁保护层相接，封场防渗层与填埋单元的侧壁防渗层相接。本发明采用刚性防渗结构和柔性防渗结构相结合的方式，不仅能够满足新标准中对刚性填埋场封场结构的要求，同时可以将渗入顶部混凝土的雨水进行收集导排；又避免了堆体沉降造成的顶部混凝土结构失稳问题，增加了封场结构的长期稳定性。
