Backfilling construction method for narrow fat groove of ultra-deep foundation pit
The invention discloses a backfilling construction method for a narrow fat groove of an ultra-deep foundation pit. Baselayer treatment after basement structure construction is completed and basement outer wall waterproof construction is conducted; waterproof protection plate installation is conducted after waterproof protection plate nails are glued and grouting steel pipe buckles are clamped; bottom layer fat groove backfilling concrete is poured (reserved test blocks) mounting grouting steel pipe buckles and dewatering well casing pipe buckles on one side of underground diaphragm wall; mounting grouting steel pipes and dewatering well casing pipes on two sides; backfilling rubble of a fertilizer groove to a designed elevation; binding steel bars of a pressure roof plate of the fertilizer groove and pouring concrete, grouting a rubble backfilled part, mounting a dewatering well water pump, and carrying out compressive strength test and foundation static load test; . The waterproof protection plate and the waterproof protection plate nails are typeset, the problem that the waterproof protection plate falls off is solved, meanwhile, the water pumping and draining equipment is installed in the water collecting well, organized dewatering and draining are conducted, and the problem that surface water and confined water are retained is solved; a material penetrating hole is reserved in the middle of the support changing plate belt and serves as a conveying channel of backfill materials.
本发明公开了一种超深基坑狭窄肥槽回填施工方法，地下室结构施工完成后基层处理并进行地下室外墙防水施工→胶粘防水保护板钉子及注浆钢管卡扣后安装防水保护板→浇筑底层肥槽回填混凝土(预留试块)→安装地下连续墙一侧的注浆钢管卡扣及降水井套管卡扣→安装两侧注浆钢管及降水井套管→肥槽碎石回填至设计标高→肥槽压顶板钢筋绑扎并浇筑混凝土→碎石回填部分注浆→安装降水井水泵→抗压强度试验及地基静载荷试验。本发明对防水保护板及防水保护板钉子进行排版，解决了防水保护板脱落的问题，同时在集水井中安装抽排水设备，进行有组织的降排水，解决了地表水和承压水滞留问题；在换撑板带的中间位置预留穿料孔，作为回填材料的运输通道。
