Description

Technical Field

[0001] The utility model relates to the technical field of cofferdam bottom sealing compartments, and more specifically, to a bottom sealing compartment structure of a hanging box cofferdam. Background Art

[0002] The truss keel of the hanging box cofferdam also serves as the bottom partition, which is a common method in construction to construct a closed space. It is usually used to provide a safe and dry working environment when constructing deep foundation pits or deep-water high pile caps of cross-sea bridges at the construction site.

[0003] Installation of the box cofferdam: First, build a series of steel box cofferdams in the water to enclose the construction area and prevent water from entering the construction area. Inside the box cofferdam, steel pipes or concrete piles are driven into the bottom of the water and fixed to the bottom of the water through special construction techniques to form a deep-water high-pile foundation. Inside the box cofferdam, according to construction needs, the construction area is divided into different rooms or areas by building partitions, truss keels and other structures to form bottom-sealed compartments. This takes a long time to construct, is inconvenient, requires a lot of materials, is not economical, and is not convenient enough to use. Utility Model Content
