According to the underwater parallel connection construction device for the steel pipe piles and the construction method of the underwater parallel connection construction device, underwater parallel connection land mounting is achieved, the mounting and dismounting difficulty is greatly reduced, the whole device is clear in structural stress, and the tensile force borne by parallel connection is borne by a steel wire rope, the temporary fixed connecting position of a first steel pipe and a second steel pipe; pressure borne by the parallel connection is resisted by the first steel pipe, so that potential safety hazards of underwater operation are eliminated, the device is few in construction procedures and easy to operate, underwater operation is avoided, large hoisting equipment is not needed, the construction cost can be greatly reduced, meanwhile, the problem that the bending moment of the pile bottom of the steel pipe pile is too large is effectively solved, and the construction efficiency is improved. The device and the corresponding construction method are wide in application range, and are particularly suitable for the terrain with the wide beach land on the two sides and the low original ground or the accidental situation that the water level rises and exceeds design estimation in the construction process.
Description
technical field [0001] The invention relates to the technical field of bridge main beam construction. More specifically, the present invention relates to an underwater parallel joint construction device for steel pipe piles and a construction method thereof. Background technique [0002] The basic construction of cross-river and sea-crossing bridges generally adopts the construction plan of building a water platform next to the foundation, changing the water operation to the land operation, and using the water steel trestle bridge as an auxiliary channel connecting the two sides of the river or reaching the water operation point. With the development of bridge construction technology, deep-water pile foundations continue to emerge, which makes the design and construction of water steel trestle bridges and water platforms more difficult. Moreover, due to the long cantilever of deep-water platform steel pipe piles, the construction cost increases accordingly. Under the action ...
