Fertilizer groove supporting retaining wall structure utilizing existing underground structure and fertilizer groove backfilling method
The invention discloses a fat groove supporting retaining wall structure utilizing an existing underground structure and a fat groove backfilling method, the fat groove supporting retaining wall structure comprises two overlapped walls, the two overlapped walls comprise multiple layers of unit wallboards overlapped together, post-pouring spaces are formed between the two opposite sides of the unit wallboards and a supporting structure of a deep foundation pit and between the two opposite sides of the unit wallboards and the underground structure of the deep foundation pit respectively, the two opposite sides of the unit wallboards are anchored in the outer walls of the supporting structure and the underground structure through embedded steel bars correspondingly, and bearing plates are formed at the bottoms of the unit wallboards. The cast-in-place concrete is poured in the post-pouring space and wraps the embedded steel bars; the tie assembly comprises a plurality of stay cables and a counter-force beam, a plurality of reserved holes are formed in the unit wallboards, the stay cables penetrate through the reserved holes, the counter-force beam abuts against the outer sides of the unit wallboards, one ends of the stay cables are connected to the counter-force beam, and the other ends of the stay cables extend to the inner sides of the unit wallboards and are connected to the supporting structure. The method solves the problems that a fertilizer groove needs to be backfilled in advance during procedure interpenetration, and the construction period is affected due to long backfilling construction time of the whole fertilizer groove.
本发明公开了一种利用既有地下结构的肥槽支护挡墙结构及肥槽回填方法，包括：两叠合墙，包括叠合在一起的多层单元墙板，单元墙板的相对两侧与深基坑的支护结构、深基坑的地下结构之间分别形成后浇空间，单元墙板的相对两侧通过植筋分别锚固于支护结构和地下结构的外墙中，单元墙板的底部形成有承压板；现浇混凝土，浇筑于后浇空间中且包覆于植筋；拉结组件，包括多根斜拉索和反力梁，单元墙板形成有多个预留孔洞，斜拉索穿设于预留孔洞，反力梁压抵于单元墙板的外侧，斜拉索的一端连接于反力梁，斜拉索的另一端伸至单元墙板的内侧且连接于支护结构。本发明解决了工序穿插需要提前回填肥槽，而肥槽全部回填施工时间长，影响施工工期的问题。
