Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0025] refer to Figure 1~4 Shown is the preferred embodiment provided by the present invention.

[0026] The method for underpinning the foundation pit support column pile provided by the present embodiment includes the following steps:

[0027] 1) Number each upright column to be replaced uniformly, and each upright column to be replaced needs to be measured, positioned and marked from the ground to each support beam 11, and the underpinning area is calibrated.

Abstract

The present invention relates to the technical field of column pile underpinning construction, and discloses a foundation pit support support column pile underpinning construction method, which includes the following construction steps: 1) Uniformly number each column pile to be underpinned, and mark the underpinning area ; 2), design and manufacture steel pipes required for construction according to actual requirements; 3), hoist the steel pipes to the underpinning area, and make the steel pipes vertically arranged, and the two ends of the steel pipes between the two support beams pass through the flanges respectively The plate is connected to the support beam, and there is a gap between the lower end of the steel pipe and the support beam; the upper end of the steel pipe located between the support beam and the bottom of the foundation pit is connected to the support beam through a flange, and the lower end of the steel pipe extends downward, embedded In the excavated piles in the bottom of the excavation. In this way, by replacing the supporting role of the underpinning column piles with steel pipes, the position of the support column piles for the foundation pit is shifted, and the problem of conflict between the support column and the main pile foundation or the beam column is solved.

Description

technical field [0001] The invention relates to the technical field of column pile underpinning construction, in particular to a foundation pit support and support column pile underpinning construction method. Background technique [0002] When the construction of a large building is started, it is generally necessary to excavate a temporary foundation pit for the foundation of the building. The foundation pit is a temporary project, and its function is to provide a space so that the foundation masonry can be carried out according to the position specified by the design. [0003] In order to ensure that the construction of the foundation pit and the surrounding environment are not damaged, a support structure will be used around the foundation pit. The support structure generally includes support columns and support beams. In order to ensure the construction period, when the main structural drawings of the building are not fixed, the foundation pit project is usually excava...
