Jacket lifting and binding process

Abstract

The invention relates to a jacket lifting and binding process. The jacket lifting and binding process comprises the following steps in sequence: a crane ship is positioned in the field; a barge leans against a wharf on the left side of the crane ship; mechanical equipment of each part is checked to determine good conditions; two main hooks are loosened, and steel wire ropes are respectively hung to corresponding lifting hooks; O-shaped lifting belts are manually mounted; constructors connect the steel wire ropes on the main lifting hooks with shackles for the lifting belts in sequence; hook hanging persons use iron rods for knocking on conduction parts of the lifting belts, so that the lifting belts are firmly bound with steel pipes at lifting point parts; after the hanging persons check each lifting point normally, the main hooks are continuously lifted up to reach a preset height; an anchor system of the crane ship is twisted to shift the ship; and a jacket is shifted above the barge, and is loosened to fall on the barge. The jacket lifting and binding process has the following advantages: lifting equipment adopts a floating crane; connecting devices adopt the O-shaped lifting belts, the steel wire ropes and the shackles; the materials are simple; the lifting is stable; and the jacket is vertically lifted, and is vertically mounted on the barge without needing such operations as turning, so that the operation is simple and easy.

Description

technical field [0001] The invention relates to the field of jackets, in particular to a process for hoisting and binding jackets. Background technique [0002] Due to the large volume of the fan jacket foundation, the general construction factories are located in rivers or seasides to facilitate transportation. The fan jacket foundation is divided into three parts: the jacket connection section, the steel platform and the fan jacket main structure. The vertical main cylinder is arranged in the middle of the upper jacket connection section, with four legs on the four sides, a steel platform in the middle, and the main structure in the lower part. Among them, there are ship members on two legs, and the ship members have railings, ladders, and cables J Ancillary facilities such as pipes. The barge is docked on the shore, and the barge is hoisted by a floating crane. [0003] The existing technology is difficult to realize the hoisting and barge of the whole jacket, and the g...

AI Technical Summary

Problems solved by technology

[0003] The existing technology is difficult to realize the hoisting and barge of the whole jacket, and the general technology can meet the requirements of the partial hoisting of the jacket. The invention patent with the patent number of 201410105484.6 mentions a horizontal piece of a large jacket across the slide. Involves the hoisting of the horizontal piece of the jacket; the invention patent with the patent number of 200910083697.2 refers to the hoisting method of the land construction of the deep water large-scale jacket, which involves the hoisting of the jacket parts

The above-mentioned patent does not involve the hoisting of the whole machine, so there are still big problems in the hoisting of the whole machine, especially the hoisting of the whole machine on the barge, which also involves the lashing on the barge, which is even more difficult
