Abstract

The invention provides a rapid construction method for a strong-stormy-wave deep sea underwater connection system. The method comprises the following steps that (1) construction preparation is carried out; (2) platform steel pipe piles are constructed; (3) underwater sleeve connection systems are manufactured in factories; (4) the underwater sleeve connection systems are transported to a steel pipe pile construction platform at a pier position through a ship; (5) a floating crane enters a site and is anchored and positioned; (6) lifting points of one sleeve connection system are connected, and a lifting appliance is installed; (7) the sleeve connection system is lifted by the floating crane, and the corresponding platform steel pipe piles are sleeved with the sleeve connection system; (8) the sleeve connection system is released downwards to a design position, and a top crossbeam is installed and fixedly connected with the lifting appliance; (9) mortar is poured in interlayer walls of the sleeve connection system and the steel pipe piles; (10) after the strength of the mortar reaches design strength, the lifting appliance is dismounted; (11) construction of mortar in other sleeve interlayer walls is carried out; (12) cyclic construction of the other sleeve connection systems is carried out, and construction of the connection systems of all the platform piles is finished. The method has the advantages that problems of deepwater construction operations carried out by frogmen are solved, the construction period is shortened, and construction investment is reduced.

Description

technical field [0001] The invention belongs to the technical field of offshore bridge engineering construction, and in particular relates to a rapid construction method of a strong wind and wave deep sea underwater connecting system. Background technique [0002] At present, the underwater connection system of offshore deep-water construction platforms at home and abroad is usually directly welded or bolted by frogman underwater. Carry out cutting and assembly welding according to the steel pipe pile spacing, and then lower the connection system as a whole to the underwater design position for underwater welding between the connection system and the steel pipe piles. The underwater operation risk of this method is relatively large, the quality is difficult to control, and the construction speed is relatively slow. Contents of the invention [0003] The problem to be solved by the invention is to avoid the underwater connection of the frogman, shorten the construction per...
