Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building, especially sink well. BACKGROUND

[0002] The underwater caisson steel shell in bridge engineering is a key structural component, and its construction technology and selection are crucial to the success of the project. In the prior art, the caisson steel shell is mainly divided into two types: island building caisson steel shell and floating caisson steel shell.

[0003] Among them, in the construction process of island building caisson steel shell, a temporary island is first built at the bridge pier position. On this artificial island, the engineering team will manufacture the first section of caisson steel shell. After the completion of this steel shell part, it is sunk into the water, and then the height is continuously increased in sections until the designed elevation is reached. This method is suitable for environments with smooth water flow and moderate water depth, and can effectively control the accuracy and safety of construction.

[0004] In contrast, floating caisson steel shell is applied to more complex hydrological environments and geographical conditions. When the water depth at the bridge pier position is large, the flow rate is fast, the navigation channel needs to be kept unobstructed, or there are environmental protection restrictions, the island building method is no longer applicable. At this time, the caisson steel shell is completely manufactured in the factory and launched into the water, and then moved to the designated bridge pier position by whole floating and accurately sunk into place. The challenge of this method is to ensure the stability and safety of the caisson steel shell during the floating process.

[0005] However, under certain use environment, the caisson steel shell needs to be processed in the dock and then floated for a long distance to the bridge pier position. During this process, due to the insufficient buoyancy of the caisson steel shell to meet the water depth requirement of the processing dock and part of the navigation route, auxiliary floating measures must be taken. Common auxiliary floating measures are usually auxiliary floating plates, especially during the installation process of the caisson steel shell, the auxiliary floating plate plays a key role in temporarily increasing the buoyancy, ensuring the stability and safety of the structure in the water.

[0006] And after the caisson is in place, the auxiliary floating plate needs to be removed to allow the caisson to sink, and the auxiliary floating plate is located at the bottom of the caisson in deep water, and the sea conditions are complex, and the safety risk of personnel diving to check the removal during the removal of the auxiliary floating plate is high.

[0010] After the floatation board is removed, the top support is disengaged from the open caisson, the bottom support is disengaged from the floatation board, and the telescopic device is restored to the natural state.

[0011] In a preferred embodiment, the fixing member is provided with a through opening in the height direction for the telescopic device to pass through.
