Construction method of structural column reserved in soil platform
The invention relates to the technical field of deep foundation pit construction, and provides a construction method for a structural column in a reserved soil platform, which comprises the following steps of: performing pile foundation construction of the structural column in the reserved soil platform according to a preset position of the structural column; at the preset position of the structural column, the pile casing is sunk to the designed elevation of the pile foundation, and earthwork in the pile casing is excavated out; prefabricating a reinforcing steel bar template structure of the structural column; according to the preset position of the structural column, a groove is formed in the top of the pile foundation, the steel bar formwork structure is hoisted into the pile casing, and one end of the steel bar formwork structure is inserted into the groove; concrete is poured into the steel bar formwork structure, and after the strength of the concrete meets the preset requirement, earthwork is symmetrically backfilled between the steel bar formwork structure and the pile casing in a segmented mode; and pulling out the pile casing. According to the construction method, the structural columns are constructed in the reserved soil platform, so that the construction of the basement main body structure is realized and the influence on the construction period of the basement main body structure is avoided under the conditions that the reserved soil platform is not excavated and the back pressure effect of the reserved soil platform on the support piles is guaranteed.
本申请涉及深基坑施工技术领域，提供了一种预留土台内的结构柱施工方法，包括：根据结构柱的预设位置，在预留土台内进行结构柱的桩基础施工；在结构柱的预设位置处，下沉护筒至桩基础的设计标高，并挖除护筒内土方；预制结构柱的钢筋模板结构；根据结构柱的预设位置，在桩基础的顶部开设凹槽，将钢筋模板结构吊入护筒中，并将钢筋模板结构的一端插入凹槽中；对钢筋模板结构浇筑混凝土，并在混凝土强度满足预设要求后，在钢筋模板结构与护筒之间对称分段回填土方；拔除护筒。通过在预留土台内进行结构柱的施工，在不挖除预留土台，保障预留土台对支护桩的反压作用时，实现对地下室主体结构的施工，避免对地下室主体结构的施工工期造成影响。
