Abstract

The invention discloses a pile foundation construction method and a pier construction method. The pile foundation construction method comprises the following steps that a steel beam is fixed to a soil body on the periphery of a preset pile hole; at least one part of a steel pipe column is placed in the preset pile hole, and the other part of the steel pipe column is exposed out of the soil body; the steel pipe column is fixed to the steel beam; and concrete is injected into the preset pile hole through the steel pipe column, so that the steel pipe column is connected with the stratum through the condensed concrete. According to the technical scheme of the pile foundation construction method, the technical problem that in the prior art, a pile foundation of a temporary support is prone to moving due to concrete buoyancy and disturbance is solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a pile foundation construction method and a bridge pier construction method. Background technique [0002] During the construction of the urban underground space station, due to the conflict between the underground space station and the above-ground facilities, the original support structure of the above-ground facilities is often removed, and a temporary support structure is built in the area where the underground space station does not interfere to temporarily support the above-ground facilities until the underground space station Construction is complete. [0003] In the prior art, the temporarily supported pile foundation needs to be embedded in the soil body. However, during the concrete pouring process, the temporarily supported pile foundation is easy to move due to the buoyancy and disturbance of the concrete, resulting in displacement of the temporary su...
