Description
Technical field
The present invention relates to the construction of jacket more particularly to a kind of techniques of jacket sectional construction, belong to offshore oil
Engineering field.
Background technique
Currently, the construction for large jacket, generallys use the mode of the horizontal construction on slideway, structure fragment one
As be to be carried out one by one around its general assembly slideway prefabricated, then, then fragment general assembly one by one, be finally completed the construction of entire jacket.
As offshore oil industry develops towards profundal zone, the design of jacket also becomes increasingly huge.Due to its huge volume, lead
Cause its place demand in building course very big, in ocean engineering project numerous today, place space will become very
It is nervous.In addition, if according to traditional horizontal construction method, construction duration is longer, and efficiency of construction is lower.
Summary of the invention
It is a primary object of the present invention to overcome disadvantages mentioned above of the existing technology, and a kind of segmentation of jacket is provided and is built
The technique made not only solves the problem of jacket place anxiety in building course, substantially increases the construction of jacket
Efficiency；Moreover, it is also possible to by segmentation while build, closed up in general assembly place, to solve the construction duration of jacket
The construction duration of jacket is greatly shortened in longer problem, reduces demand of the construction to place of jacket.
The purpose of the present invention is implemented by the following technical solutions:
A kind of technique of jacket sectional construction, it is characterised in that: jacket is divided into several segmentations and is built on slideway,
And several segmented catheters framves are transported into final general assembly place one by one and are closed up；Specifically use following construction step:
The first step is put slideway block, piston shoes and is faced on the setting position of jacket build the side according to Ground arrangement figure
When support；
Second step puts the bottom surface conduit of the first segmented catheters frame and lacing wire in central truss, and complete institute on piston shoes
There is the assembling of bottom surface conduit and lacing wire；
Third step completes the installation of first layer horizontal plate in central truss on slideway；
4th step completes the installation of side flower piece in central truss on slideway；
5th step completes the installation of lacing wire in bulk in central truss on slideway；
6th step is completed in central truss, the installation of opposite side flower piece on slideway；
7th step completes the installation of top cramp in central truss on slideway；
8th step arranges temporary support on the outside of slideway, completes the installation of the first segmented catheters frame central truss external structure；
9th step, the first segmented catheters frame build after the completion of, installation the first segmented catheters frame transport reinforce, to its entirety into
Performing check removes the temporary support arranged in building course after the assay was approved；
Self-traveling module transport vehicle is driven to the lower section of the first segmented catheters frame by the tenth step, by jacking transportation pad
Pier top plays the first segmented catheters frame and piston shoes and then slowly travels self-traveling module transport vehicle, and by before harbour
The trestle on edge travels upper barge；
11st step, self-traveling module transport vehicle stop after travelling one section, after the completion of waiting barge tune to carry, after continuing
It sails；
12nd step repeats the process of the 11st step, until self-traveling module transport vehicle drives on barge completely；
Then 13rd step, fixed self-traveling module transport vehicle and the first segmented catheters frame undock barge,
And self-traveling module transport vehicle and the first segmented catheters frame are transported to general assembly place harbour；
14th step jacks up the first segmented catheters frame using self-traveling module transport vehicle, so after the completion of barge mooring
Afterwards, the forward position of the trestle of stern is slowly driven to, self-traveling module transport vehicle begins through trestle and travels to general assembly place；
15th step, will self-traveling module transport vehicle travel one section after stop, after continuing after the completion of waiting barge tune to carry
It sails；
16th step repeats the process of the 15th step, until self-traveling module transport vehicle drives to general assembly place completely
On；
Self-traveling module transport vehicle is transported the first segmented catheters frame to final total holding position, by first by the 17th step
Segmented catheters frame is placed on slideway block, then, then self-traveling module transport vehicle is withdrawn from；
18th step repeats the first to the 17th step, completes the construction and transport of the second segmented catheters frame, and in general assembly field
On the ground, using self-traveling module transport vehicle carry out final group to it is in place, gradually close up each segmentation；
19th step completes the installation and airtight experiment of conduit shelf attachment, cuts off interim transport and reinforces, just completes entirely to lead
The construction of pipe support.
In 8th step, central truss external structure during installation, the principle followed are as follows: from the front to the back, from inside to outside,
It gradually installs from bottom to top.
It in 9th step, after the completion of the first segmented catheters frame is built, integrally tests, examines to the first segmented catheters frame
After testing qualification, the temporary support that jacket is arranged in building course is removed.
In tenth step, before the transport of self-traveling module transport vehicle, first in jacket corresponding position installation and transportation
Reinforce.
The transport buttress is in the top of transport pad pier.
Beneficial effects of the present invention: the present invention due to the adoption of the above technical scheme, not only solves jacket and is building
The problem of place anxiety in the process, substantially increases the efficiency of construction of jacket；Moreover, it is also possible to by different segmentations while build
It makes, is closed up in general assembly place, so that the construction duration of jacket be greatly shortened, reduce the construction of jacket to place
Demand.
