Problems solved by technology

[0005] 3) Due to the large size of the plane and the heavy weight of the temporary outer wall, it is not suitable to adopt the construction method of integral installation due to the limitation of lifting equipment
[0006] At present, the soil and water retaining structure commonly used in bridge engineering foundation construction is the steel cofferdam structure. The steel cofferdam structure needs to be embedded in the soil or suspended and fixed on the pile foundation to form a stable structure, and the water is stopped by pouring underwater bottom sealing concrete. , obviously cannot meet the requirements of stepped caisson construction

Abstract

The invention discloses an open caisson temporary outer wall system quick to mount and dismount. The system is connected with a step of a step type open caisson foundation and comprises a steel outerwall structure, a fastening and separating device and an inner supporting system; the fastening and separating device is located at the bottom of the steel outer wall structure and can be sealed withan open caisson contact surface in a fastened manner or separated from the open caisson contact surface; and the inner supporting system is located between the steel outer wall structure and the opencaisson wall to provide lateral support to the steel outer wall structure. The system is good in water stop effect, high in structural stability, good in soil retaining and water retaining effect, convenient and quick to mount and dismount, very little in underwater operation and high in safety, does not occupy large hoisting equipment and fully meets various requirements of step type open caissonconstruction.

Description

technical field [0001] The invention relates to the field of bridge engineering foundation construction. More specifically, the present invention relates to a caisson temporary outer wall system and its construction method which can be quickly assembled and disassembled. Background technique [0002] With the take-off of my country's economic strength and the continuous improvement of bridge construction levels, the construction of long-span bridges has become a trend. The caisson foundation has the advantages of high bearing capacity, good integrity, high rigidity, and wide application of geological conditions, and is widely used. It is used in the foundation construction of long-span bridges. In the case of large water depth and large caisson size, local scour easily occurs around the pier foundation structure, which affects the stability and safety of bridge engineering. In order to reduce the weight of the caisson structure and reduce the scour depth, the caisson structu...
