Construction method for anti-seepage structure of bottom plate pile head of dump pit
The invention relates to a construction method of a dump pit bottom plate pile head anti-seepage structure. The construction method comprises the steps of breaking and removing a pile head, laying a concrete cushion layer, laying a tiled anti-seepage film, laying an enclosure anti-seepage film, pouring fine aggregate concrete, arranging a rigid waterproof layer on an exposed part of the pile head, pouring reinforced concrete and the like. The anti-seepage film protection layer is adopted between the pile head and the concrete cushion layer at the bottom of the dump pit for sealing, the sealing area is large, the anti-seepage film is high in tensile strength, large in elasticity and good in tear resistance and aging resistance, and leakage caused by differential settlement can be effectively prevented; in addition, cost is low, non-toxic and environment-friendly effects are achieved, construction flexibility is high, laying is convenient, and construction requirements of different projects can be met.
本发明涉及一种垃圾坑底板桩头防渗结构施工方法，包括桩头破除、铺设混凝土垫层、铺设平铺防渗膜、铺设围护防渗膜、浇筑细石混凝土、桩头外露部分设刚性防水层及浇筑钢筋混凝土等步骤。本发明在桩头与垃圾坑底部混凝土垫层之间采用防渗膜防护层密封，密封面积大，并且防渗膜的抗拉强度高、弹性大、抗撕裂性及抗老化性好，可有效防止不均匀沉降导致的渗漏；另外其成本低、无毒环保、施工灵活性强、铺设方便，能够满足不同工程的施工需要。
