Embodiment Construction

[0063] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0064] Such as Figure 1~4 As shown, the present invention provides a caisson construction structure, comprising:

[0065] A plurality of cast-in-place piles 1 symmetrically arranged at the bottom of the foundation pit to be excavated;

[0066] The top of each cast-in-place pile 1 is connected with a steel pipe column 2, and the bottom end of each steel pipe column 2 is connected with the top of the corresponding cast-in-place pile 1, and the steel pipe column 2 extends from the foundation pit to be excavated to the ground 3;

[0067] A steel structure platform 4 connecting all steel pipe columns 2, the steel structure platform 4 is perpendicular to the steel pipe column 2;

[0068] a jack 5 arranged at the top of each steel pipe ...

Abstract

The present invention provides a caisson construction structure and a construction method thereof. The present invention provides a steel pipe column cast-in-place pile guided controllable caisson construction structure, in which a pipe section column is connected to the top of each two-way jack, and the steel pipe column The corbels are erected on the pipe joint column as an important guiding component in the sinking process of the caisson. When the caisson needs to sink, the soil in the foundation pit in the space surrounded by the steel pipe column can be continuously excavated. At the same time, the lowermost steel corbel A erected on the pipe section column is removed, and then the caisson can rely on its own gravity to sink to the position where the steel corbel B on the upper part of the steel corbel A is erected on the pipe section column . In addition, in the process of caisson descending, if inclination occurs, the height of the pipe joint column of the jack pair can be adjusted to ensure that the caisson always maintains a vertical state during the caisson descending process, thereby effectively controlling the verticality during the caisson descending process And stability, convenient construction and reduce construction risk, save cost.

Description

technical field [0001] The invention relates to a caisson construction structure and a construction method thereof. Background technique [0002] Caisson is a construction technique for building deep foundations and underground structures. During construction, a reinforced concrete well body with openings is first made on the ground or in the foundation pit. After it reaches the specified strength, the soil is excavated and transported out in layers inside the well body. With the excavation and soil surface lowering, the caisson well body is Overcome the frictional resistance between the soil wall and the counterforce of the blade foot with the help of self-weight or other measures, and continue to sink until the design elevation is in place, and then seal the back. [0003] The advantages of caisson construction technology are: deep (up to 50 meters) underground works can be constructed in a narrow site, and the impact on the surrounding environment is small; construction ...
