Construction method of internal support lattice stand column pile
The invention relates to the field of foundation pit inner support supporting structures, in particular to a construction method of an inner support lattice stand column pile, which comprises the following steps of: pressing a prestressed pipe pile into the ground; and a reinforcement cage is inserted into the pile top of the prestressed pipe pile, the reinforcement cage and the reinforcement framework of the supporting beam are connected into a whole, concrete is poured into the pile top and the mold of the supporting beam at the same time, and after the concrete is solidified, the pile top, the reinforcement cage and the supporting beam are connected into a whole. According to the embodiment of the invention, the prestressed pipe piles are adopted as the inner support lattice stand column piles, the prestressed pipe piles and the support beams are combined into a whole to form the foundation pit inner support supporting structure, and the problems that a traditional steel lattice stand column is low in shearing resistance and bending resistance, rotary excavating equipment needs to be introduced when the steel lattice stand column is built in a foundation pit, and the construction cost is low are solved. And the construction cost and the construction period are increased.
本发明涉及基坑内支撑支护结构领域，具体涉及一种内支撑格构立柱桩的施工方法，包括下述步骤：将预应力管桩压入地下；在预应力管桩的桩顶的内部插入钢筋笼，钢筋笼与支撑梁的钢筋骨架连接为一体，在桩顶的内部和支撑梁的模具内部同时浇筑混凝土，混凝土凝固之后，桩顶、钢筋笼和支撑梁连接为一体。本发明的实施例采用预应力管桩作为内支撑格构立柱桩，将预应力管桩与支撑梁结合为一体以形成基坑内支撑支护结构，解决了传统的钢格构立柱的抗剪和抗弯强度较低，在基坑内部建设钢格构立柱需要引入旋挖设备，增加施工成本和工期的技术问题。
