Deep foundation pit caisson type sump construction method
The invention discloses a construction method for a caisson type sump of a deep foundation pit, which comprises the following steps of: when a foundation construction working surface is higher than an underground water level, prefabricating a reinforced concrete prefabricated part of which the size is consistent with that of the sump, then digging the sump to a standard depth, and putting the prefabricated part into the sump. A connecting steel bar is reserved at one end of the prefabricated part, the connecting steel bar is located above the prefabricated part, the connecting steel bar is woven into a raft steel bar, a raft template is built to form a raft cavity, and concrete is poured into the raft cavity to form a raft, so that the foundation construction difficulty of a building can be simplified; construction of the sump is achieved when the foundation construction working face is higher than the underground water level, and the situation that the construction period of a building foundation is affected when the foundation construction working face is higher than the underground water level can be prevented.
本申请公开了一种深基坑沉箱式集水坑施工方法，在基础施工工作面低于地下水位的高度较高时，预制与集水坑尺寸相符的钢筋混凝土预制件，而后将集水坑挖至标准深度，将预制件放至集水坑内。预制件的一端预留出连接钢筋，且使连接钢筋位于预制件上方，并将连接钢筋编进筏板钢筋内，搭建筏板模板形成筏板型腔，将混凝土浇筑至筏板型腔内形成筏板，这样可以简化建筑物的基础施工的难度，实现基础施工工作面低于地下水位的高度较高时集水坑的施工，且可防止基础施工工作面低于地下水位的高度较高时影响建筑物基础施工的工期。
