Construction method of stand column pile
The invention relates to a construction method of a stand column pile. The construction method comprises the following steps: forming a pile hole according to to-be-constructed stand column pile construction; providing a reinforcement cage and a steel pipe and concentrically arranging and fixedly connecting the steel pipe and the reinforcement cage into a whole; integrally hoisting the reinforcement cage and the steel pipe above the pile hole, aligning the centers of the reinforcement cage and the steel pipe to the center of the pile hole and inserting the reinforcement cage and the steel pipeinto the pile hole; and pouring concrete into the pile hole to form the stand column pile. The concentric arrangement of the reinforcement cage and the steel pipe is ensured and deflecting and sinking of the reinforcement cage can be prevented. The problems in the prior art that the reinforcement cage is hoisted into the stand column pile hole, then the bottom end of the steel pipe is inserted into the reinforcement cage, then the reinforcement cage and the steel pipe are welded and fixed to the orifice, it is difficult to ensure that the reinforcement cage and the steel pipe are stable in position and it is difficult to ensure that the fixed steel pipe and the reinforcement cage are concentrically arranged can be solved.
本发明涉及一种立柱桩的施工方法，包括如下步骤：根据待施工的立柱桩施工形成桩孔；提供钢筋笼和钢管，将钢管和钢筋笼同心设置并固接成一体；整体吊装钢筋笼和钢管至桩孔上方，将钢筋笼和钢管的中心对准桩孔的中心下放插设于桩孔内；对桩孔灌注混凝土以形成立柱桩，保证了钢筋笼和钢管同心设置，防止了钢筋笼偏位下沉，解决现有技术中先将钢筋笼吊放于立柱桩孔内，接着将钢管的底端插设于钢筋笼内，然后在孔口处焊接固定钢筋笼和钢管，此时难以保证钢筋笼和钢管位置稳定，难以保证固定后钢管和钢筋笼同心设置的问题。
