Description

A kind of building technology of offshore boosting station lower component

Technical field

The invention belongs to marine transportation manufacturing fields, and in particular to a kind of building technology of offshore boosting station lower component.

Background technique

With the huge consumption of fossil energy and the serious pollution of environment, it is each that renewable energy receives the world more and more The concern of state, wind energy become most competitive one of new energy, compare land wind-powered electricity generation, and offshore wind farm is not only not take up soil money Source, and energy abundance, power output are stablized, utilization rate is high, it has also become the new direction of world's Wind Power Development.Currently, China is being built If the most offshore 10-30km of coastal waters wind-powered electricity generation, project planning capacity be 200-300kw, You Duotai 3mw-6mw offshore wind turbine group Power generation concentrates power transmission to offshore boosting station, then the boosting of the main transformer through offshore boosting station to send via submarine cable current collection link To substation on the bank complete electric power send out, therefore, offshore boosting station become offshore wind farm power generation send out most important link it One.

Lower component plays the role of a supportive to entire offshore boosting station, thus the edge rolling to lower component, cutting, The requirement welded, make and closed up is very stringent, when traditional offshore boosting station lower component is built, has the following disadvantages: Since structure is larger when lower component is built, lower component monoblock type construction difficulty is bigger, takes time and effort simultaneously, and step is complicated In disorder and low to edge rolling and cutting requirement when construction, welding is unstable, and poor welding quality largely reduced lower component Connection precision and supportive bring certain unstability to entire offshore boosting station.

Summary of the invention

In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide, a kind of processing step orderliness is orderly, and manufacture is smart Degree is high, improves efficiency of construction, improves the building technology of the offshore boosting station lower component of stability.

In order to solve the above technical problems, the technical solution adopted by the present invention are as follows: a kind of offshore boosting station lower component is built Make technique, lower component is one to be vertically arranged and its lower end extends to the jacket of the following supporting course of sea bed, and jacket includes more A steel-pipe pile, steel-pipe pile include vertical portion and rake, and the lower end of the rake and the upper end of vertical portion connect, tilt simultaneously The upper end in portion, which slopes inwardly, to be arranged, and the rake of multiple steel-pipe piles is corresponding in turn to setting, while the upper end position in adjacent inclined portion Between, the first singletree, the second singletree, third singletree are respectively equipped between medium position, between lower end position, it is adjacent to incline Two hounds arranged in a crossed manner are equipped between inclined portion, the center of hound is connect with the center of the second singletree, multiple inclinations A platform is equipped between the upper end in portion, which is placed in the top position of the first singletree, while the outer ring of the platform is set respectively There is fence, the rake upper end of any steel-pipe pile is equipped with the vertically arranged ladder of a book;

A kind of building technology of offshore boosting station lower component, first be respectively segmented after horizontal construction again it is vertical close up welding, Steps are as follows: (1) steel plate presses the blanking of jacking figure;(2) scribing line, beveling and cutting;(3) steel-pipe pile, singletree and hound are made; (4) close up welded steel pipe pile, singletree, hound.

Further, the specific steps of which are as follows:

(1) steel plate presses the blanking of jacking figure: cutting drawing and cutting instruction journey are carefully checked according to jacking figure blanking, before cutting Sequence avoids miscut, to make a record in cutting process, and every block of steel plate of cutting will check steel plate furnace lot number, makes a record, In addition every piece of part of well cutting will have corresponding label, not repeat to cut, the plate and clout of well cutting will rationally divide It criticizes and stacks;

(2) scribing line, beveling and cutting: the scribing line of jacket stull pipe and down tube is very crucial, and important scribing line must lead to Computer cutting instruction repertorie is crossed to generate, in cutting stock, that is, powder marking, content includes inside and outside the support tube of bevel cut Longitudinal etc. up and down point of inspection line of cylinder intersection and detecting size, and determine test point and cut point, to all inspection lines And key point, it is required to be marked with ocean punching;Welding groove is correctly cut according to the details in jacking figure and construction drawing, Down tube intersection and its groove hand cut again after cylinder splicing;

(3) steel-pipe pile, singletree and hound are made: being checked first according to the drawing that design department provides and is familiar with every The machined parameters of one block of plate control the processing dimension of each block of plate after processing, respectively add 100mm's to plate edge rolling direction both ends Machining allowance;Secondly, rotating suitable attitude according to steel-pipe pile, singletree, the diameter of hound, wall thickness, then carry out It rolls, rolls to be located on veneer reeling machine and disposably complete;Again, to the weld seam between steel-pipe pile, singletree and hound into Row welding after the completion of welding, checks the circularity of steel-pipe pile, singletree and hound;

(4) close up welded steel pipe pile, singletree, hound: after steel-pipe pile of having good positioning, lifting singletree and diagonal brace respectively Bar, spot welding singletree and hound after lifting in place;The middle part surplus of hound is cut, and passes through ring with singletree medium position Stitch spot welding positioning;Welded steel pipe pile and Lincoln weld being used when singletree, first welding bead being cleaned out before welding, when welding is first To welding on the inside of cylinder, then outside carbon digs back chipping, capping, and when positioning, the twice longitudinal plate in adjacent cylinder sews on lower mistake 90 ° are opened, lateral loops are stitched to the weld seam overlapping of rare 50mm or more, and the strengthening of welded seam in beginning and end region must not exceed 3mm.

Beneficial effects of the present invention are as follows:

1, close up welding, building technology item by vertical again after each segmentation first horizontal construction when the present invention builds lower component Reason orderly, greatly improves efficiency of construction, and the jacket of lower component passes through steel-pipe pile, the first singletree, the second singletree, third The setting of singletree and hound ensure that the support stability that lower part is set up, to guarantee the long-term fortune of offshore boosting station Row maintenance, and steel-pipe pile includes vertical portion and intilted rake, substantially increases the supportive of lower component, is not easy Run-off the straight.

It 2, include steel plate when lower component is built by the blanking of jacking figure, scribing line beveling and cutting, production steel-pipe pile and singletree And hound, close up welded steel pipe pile and singletree level-one hound, and it is high to edge rolling and cutting requirement, using adopting With submerged-arc welding, welding quality stable, welding productivity are high, few without arc light, flue dust;Rationally reserved welding surplus, guarantees welding matter Amount and welding precision, substantially increase the supportive of lower component, certain stability are brought to entire offshore boosting station.
