Problems solved by technology
[0003] In order to overcome the defects existing in the existing technology, we now provide a pile-column integrated structure and its construction method by the first-insertion method to solve the difficulty in transportation of the pile-column integrated structure by the traditional post-insertion method and the problems of the inner and outer concrete of the steel pipe column and the surrounding steel plates. Combination effects are difficult to control

The invention discloses a pre-insertion method pile-column integrated structure and a construction method thereof.A steel pipe column of the structure is in an opening form, a shear ring is arranged outside the steel pipe column, then the steel pipe column is easier and more convenient to machine and transport, and compared with a traditional stud method, the damage risk of the steel pipe column is reduced; the concrete of the concrete supporting pile is prevented from flowing back upwards to the exterior of a column body of the steel pipe column, the concrete of the concrete supporting pile is pressed through an anti-gushing device arranged outside the steel pipe column, and core concrete in the steel pipe column is poured to the top of the steel pipe column at a time in the steel pipe column. The concrete of the concrete supporting pile and the core concrete in the steel pipe column can be integrally poured, the pouring integrity is good, and the construction quality is easy to control. The method solves the problems that a pile-column integrated structure is difficult to transport and the combination effect of concrete inside and outside the steel pipe column and surrounding steel plates is difficult to control in a traditional post-insertion method process.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a pile-column integrated structure and a construction method thereof. Background technique [0002] Pile-column integrated construction, as a common form of top-down method, is applied in the construction of engineering piles and superstructure columns constructed by top-down method, in order to save construction period or other purposes. The common upside-down construction method adopts the post-insertion process for the intermediate piles, using tool columns to connect long steel pipes, the bottom of the steel pipes is closed with conical steel plates, and the walls of the steel pipe columns are installed with studs, which puts forward higher requirements for the transportation and processing of steel pipe columns . The post-insertion method also has higher requirements on the retarding time of the concrete. At the same time, the lower end of the steel pipe is co...
