Static pressure type open caisson machine

Abstract

The invention provides a static pressure type open caisson machine. The static pressure type open caisson machine comprises a first base, a second base, connecting parts and a clamping part, wherein the number of the connecting parts is two, each connecting part comprises a first supporting column, a second supporting column and a connecting column, the first supporting columns are fixedly connected to the first base, the second supporting columns are fixedly connected to the second base, the first supporting column and the second supporting column are connected through the connecting column, the clamping part comprises a first arc-shaped piece, a second arc-shaped piece, a first connecting block, a second connecting block and a third arc-shaped piece, and fixing devices are fixedly connected to the side walls of the first base and the second base. According to the static pressure type open caisson machine, the open caisson construction can be accurately and rapidly completed.

Description

technical field [0001] The invention relates to the technical field of caissons, in particular to a static pressure caisson machine. Background technique [0002] The caisson is a shaft-shaped structure. It excavates the soil in the well and sinks to the design elevation after overcoming the friction of the well wall by its own gravity, and then uses concrete to seal the bottom and fill the well hole, making it used for shield construction and pipe jacking construction. working wells, or become the foundation of bridge piers and other structures. Because the caisson structure has high rigidity, large depth and good integrity, it is also widely used in various types of projects. [0003] In the traditional caisson construction, the caisson is sunk by its own weight, and the excavation of earthwork runs through the whole construction process of the caisson, and generally adopts manual excavation or small mechanical excavation, and the excavation time is long. In addition, be...

[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
