Abstract

The invention relates to the technical field of support structure construction and discloses a construction method of a pile-column integrated structure. The pile-column integrated structure comprisesa cast-in-place pile formed below a foundation and a steel pipe column, wherein the steel pipe column is connected to the cast-in-place pile and extends to the portion above the foundation. The construction method comprises the following steps of S1, construction of a pile hole, wherein the construction position of the pile-column integrated structure on the foundation is measured, and the pile hole is formed in the foundation in a rotary excavating mode; S2, pouring of the cast-in-place pile, wherein a steel reinforcement cage and a guide pipe are placed into the pile hole, and concrete is pumped and poured into the pile hole through the guide pipe; S3, insertion of a steel pipe, wherein the lower end of the steel pipe is inserted into the cast-in-place pile, and a gap between the steelpipe and the pile hole is subjected to backfilling; S4, installation of the steel reinforcement cage in the steel pipe, wherein the steel reinforcement cage is installed in the steel pipe; S5, pouringof the steel pipe column, wherein after the concrete of the cast-in-place pile initially sets, the concrete is poured into the steel pipe, the steel pipe column is formed after the concrete sets, andthe cast-in-place pile and the steel pipe column form the pile-column integrated structure. The pile-column integrated construction structure constructed by means of the method is stable and firm.

Description

technical field [0001] The invention relates to the technical field of support structure construction, in particular to a construction method of a pile integrated structure. Background technique [0002] In the basement underpinning project, the basement construction is similar to the cover-and-excavation construction method. First, the pile foundation, basement frame columns, and underpinning beams are constructed to complete the overall underpinning of the upper structure, and then the basement earthwork, column cutting, and original removal are performed. Foundation, basement floor construction, basement roof construction, basement main construction completed. [0003] During this process, how to control the uneven settlement of the foundation is the key issue to ensure the safety of the superstructure. There are two main factors affecting foundation settlement: one is the rise and fall of groundwater, and the other is the disturbance of foundation soil. Therefore, the ...
