A static pressure caisson

Abstract

The present invention provides a static pressure caisson, comprising a first base, a second base, a connecting part, and a clamping part, two connecting parts are provided, and the connecting part includes a first support column, a second support column, The connecting column, the first supporting column is fixedly connected to the first base, the second supporting column is fixedly connected to the second base, the first supporting column and the second supporting column are connected through the connecting column; the clamping part includes a first arc-shaped piece, The second arc piece, the first connection block, the second connection block and the third arc piece, the side walls of the first base and the second base are all fixedly connected with fixing devices. The invention can accurately and rapidly complete caisson construction.

Description

Technical field [0001] The present invention relates to the technical field of sinking, specifically to a hydrostatic sinker. Background [0002] Sinking well is a wellbore-like structure, which is dug in the well, relying on its own gravity to overcome the friction resistance of the well wall and sinking to the design elevation, and then using concrete to seal the bottom and fill the wellhole, so that it can be used as a shield construction, pipe jacking construction work well, or become the foundation of bridge piers and other structures. Because the sinking structure has high stiffness and large depth, integrity is good, it is also widely used in a variety of different types of engineering. [0003] In the traditional sinking construction, the sinking well relies on its self-weight to sink, and the excavation of the earthwork runs through the whole process of the construction of the sinking well, and generally uses manual excavation or small mechanical excavation, and the exca...

Problems solved by technology

[0003] In the traditional caisson construction, the caisson is sunk by its own weight, and the excavation of earthwork runs through the whole process of caisson construction, and generally adopts manual excavation or small mechanical excavation, and the excavation time is long

In addition, before the construction of traditional caissons, it is generally required to build high-pressure jet grouting piles around the well to prevent the well wall from collapsing during the excavation process, causing the surrounding ground to collapse, and the construction of high-pressure jet grouting piles will generate additional construction facilities costs and time, resulting in long construction period and high construction cost of the caisson
