Construction method of pile box type underground building retaining wall and retaining wall
The invention belongs to the field of civil engineering, and provides a pile box type underground building retaining wall construction method and a retaining wall. The construction method of the pile box type underground building retaining wall comprises the steps that a cast-in-situ bored pile is constructed in a set construction area, earthwork is excavated to the designed elevation position of the bottom of the pile box type retaining wall, then a pile head is chiseled away, and cast-in-situ pile reinforcing steel bars on the lower portion of a structural side wall are controlled to penetrate through a reinforcing steel bar cage of a retaining wall bottom plate and can reach a main reinforcement area of the retaining wall and the structural side wall; the cast-in-place pile, the bottom plate and the structural side wall are effectively connected; a formwork is erected, bottom plate concrete is poured, and chiseling treatment is conducted on the concrete at the structural side wall pouring position after formwork removal; reinforcing steel bars of the side wall of the box-type structure and the side wall of the retaining wall are bound and effectively connected with the bottom plate inward-extending reinforcing steel bars and the cast-in-place pile inward-extending reinforcing steel bars, and then a formwork is erected to pour concrete of the retaining wall and the box-type structure; and after pouring is completed, earthwork is backfilled and compacted on the retaining side of the retaining wall and the upper area of the box-type structure, and the pile box-type underground building retaining wall is constructed.
本发明属于土木工程领域，提供了一种桩箱式地下建筑物挡土墙施工方法及挡土墙。其中，桩箱式地下建筑物挡土墙施工方法包括在设定施工区域施工钻孔灌注桩，开挖土方至桩箱式挡土墙底设计标高处，再凿除桩头，控制结构侧墙下部的灌注桩钢筋穿过挡土墙底板钢筋笼并可到达挡土墙和结构侧墙的主筋区域；将灌注桩、底板与结构侧墙三者有效连接；架设模板浇筑完成底板混凝土，待拆模后在结构侧墙浇筑位置处对混凝土进行凿毛处理；绑扎箱型结构侧墙和挡土墙侧壁的钢筋，并与底板内伸钢筋、灌注桩内伸钢筋有效连接后，架设模板浇筑挡土墙和箱型结构混凝土；浇筑完成后，在挡土墙挡土侧和箱型结构上部区域回填土方压实，建造完成桩箱式地下建筑物挡土墙。
