Abstract

The invention discloses a completely recoverable tongue-and-groove block assembling section steel bottom plate of a steel suspension box under a complicated oceanic condition. The bottom plate comprises an assembling bottom plate, wherein the assembling bottom plate comprises a middle bottom plate B; bottom plates A are symmetrically arranged on the two sides of the bottom plate B and are in buttjoint together in a tongue-and-groove manner; arch notches allowing steel pile casings to penetrate through are formed in the bottom plates A; middle opposite pulling finish rolling threaded steel transversely penetrating through the bottom plates A and the bottom plate B is arranged in the middle of the assembling bottom plate; threaded steel suspension and lowering holes are formed in the bottomplates A and the bottom plate B; construction platform supports perpendicularly extend out from the periphery of the assembling bottom plate; after bearing platform construction is finished, the assembling section steel bottom plate can be completely dismounted, and recycled; no loss is caused; and much steel product input and construction cost are saved.

Description

technical field [0001] The invention relates to the technical field of bridge foundation construction, in particular to a block-and-groove assembled steel bottom plate with fully recoverable steel suspension boxes in complex sea conditions. Background technique [0002] Under the complex sea conditions with large waves, the high pile caps are constructed with steel hanging boxes. The huge wave force is a huge challenge to the overall stability of the steel hanging box floor structure. For the construction of steel hanging box cofferdam under similar conditions, the steel hanging box bottom plate commonly used in China is the layered bottom plate of ordinary main keel and sub keel, and the bottom plate needs to weld the main keel and sub keel panels into a whole on site to resist the huge wave force. The impact will increase a lot of on-site welding workload, and the bottom plate is welded into a whole on site, which cannot be recovered underwater at all. The construction co...
