Composite anti-seepage structure suitable for industrial solid waste landfill
The invention discloses a composite anti-seepage structure suitable for an industrial solid waste landfill, and belongs to the technical field of landfill seepage prevention. The structure comprises a leveling layer, an air guide layer/underground water guide and drainage layer, a concrete composite impermeable layer and a drainage layer/leachate guide and drainage layer which are sequentially arranged from bottom to top. The concrete composite impermeable layer comprises a two-way reinforcing mesh, transverse and vertical reinforcing ribs, a double-rough-surface HDPE film, a concrete surface layer and an anchoring body, and the two-way reinforcing mesh, the transverse and vertical reinforcing ribs and the double-rough-surface HDPE film are wrapped in the concrete surface layer; the anchoring body is formed by drilling holes in a reservoir area slope soil body or an industrial solid waste pile body, inserting main reinforcements and injecting cement paste to wrap the main reinforcements; and the main ribs are connected with the two-way reinforcing mesh and the transverse and vertical reinforcing ribs, so that the concrete surface layer and the anchoring body form a whole. According to the invention, the stability of the side slope can be obviously improved, so that the industrial solid waste landfill and the industrial solid waste heap can be provided with steep side slopes, and the storage capacity is increased or the occupied area is reduced under the condition that the storage capacity is not changed.
本发明公开了一种适用于工业固废填埋场的复合防渗结构，属于填埋场防渗技术领域；其包括：自下而成依次设置的找平层、导气层/地下水导排层、混凝土复合防渗层和排水层/渗滤液导排层；混凝土复合防渗层包括双向钢筋网、横竖向加强筋、双糙面HDPE膜、混凝土面层和锚固体，双向钢筋网、横竖向加强筋和双糙面HDPE膜包裹在混凝土面层内；锚固体采用在库区边坡土体或工业固废堆体中钻孔后插入主筋，并注入水泥浆包裹主筋形成；主筋与双向钢筋网和横竖向加强筋相连接，以使混凝土面层与锚固体构成一整体。本发明可显著提高边坡稳定性，进而可以使工业固废填埋场和工业固废堆体设置较陡的边坡，增加库容或库容不变情况下减少占地面积。
