Description

A kind of building technology of offshore boosting station lower component

Technical field

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

Background technology

With the huge consumption of fossil energy and the serious pollution of environment, it is each that regenerative resource receives the world more and more The concern of state, wind energy turns into most one of new energy of competitiveness, and compared to land wind-powered electricity generation, offshore wind farm is not only not take up soil money Source, and energy abundance, stable, utilization rate height of contributing, it has also become the new direction of world's Wind Power Development.At present, China is built If the most offshore 10-30km of coastal waters wind-powered electricity generation, project planning capacity is 200-300kw, by more 3mw-6mw offshore wind turbines groups Generate electricity, power transmission is concentrated to offshore boosting station via submarine cable current collection link, then the main transformer boosting through offshore boosting station is sent To transformer station on the bank complete electric power send out, therefore, offshore boosting station turn into offshore wind farm generate electricity send out most important link it One.

Lower component plays the effect of supportive to whole offshore boosting station, thus the edge rolling to lower component, cutting, The requirement welded, make and closed up is very strict, when traditional offshore boosting station lower component is built, has the disadvantage that: Because 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 split requirement during construction, welding is unstable, poor welding quality, largely reducing lower component Precision and supportive are connected, certain unstability is brought to whole offshore boosting station.

The content 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 is: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 Individual 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, tilted simultaneously The upper end in portion, which slopes inwardly, to be set, 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, the 3rd singletree are respectively equipped between medium position, between lower end position, it is adjacent to incline Two hounds arranged in a crossed manner are provided between inclined portion, the center of hound is connected with the center of the second singletree, multiple inclinations A platform is provided between the upper end in portion, the platform 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 provided with the vertically arranged cat 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, its step It is as follows:(1)Steel plate presses jacking figure blanking;(2)Line, beveling and cutting;(3)Make steel-pipe pile, singletree and hound;(4) Close up welded steel pipe pile, singletree, hound.

Further, it is comprised the following steps that:

(1)Steel plate presses jacking figure blanking:According to jacking figure blanking, cutting drawing and cutting instruction repertorie are carefully checked before cutting, is kept away Exempt from miscut, to be made a record in cutting process, every block of steel plate of cutting will check steel plate furnace lot number, make a record, in addition Every piece of part of well cutting will have corresponding mark, not repeat to cut, and the sheet material and clout of well cutting will reasonable heaps in batches Put;

(2)Line, beveling and cutting:The line of jacket stull pipe and down tube is very crucial, and important line must pass through electricity Brain cutting instruction repertorie produces, and is powder marking in cutting stock, and content includes cylinder inside and outside the support tube of bevel cut Line is examined in longitudinal direction etc. point up and down of intersection and detected size, and determines test point and cut point, to all inspection lines and pass Key point, it is required to be marked with ocean punching;Welding groove, diagonal brace are correctly cut according to the details in jacking figure and construction drawing Pipe intersection and its groove hand cut again after cylinder splicing;

(3)Make steel-pipe pile, singletree and hound:The drawing provided first according to design department is checked and is familiar with each piece The machined parameters of sheet material, the processing dimension of each block of plate is controlled after processing, sheet material edge rolling direction both ends are respectively added with 100mm processing Surplus;Secondly, suitable attitude is rotated according to steel-pipe pile, singletree, the diameter of hound, wall thickness, then rolled, Roll to be positioned on veneer reeling machine and disposably complete;Again, the weld seam between steel-pipe pile, singletree and hound is welded Connect, after the completion of welding, check the circularity of steel-pipe pile, singletree and hound;

(4)Close up welded steel pipe pile, singletree, hound:Have good positioning after steel-pipe pile, lift singletree and hound respectively, Spot welding singletree and hound after lifting in place;The middle part surplus of hound is cut, and passes through circumferential weld with singletree medium position Spot welding positions;Lincoln weld is used when welded steel pipe pile and singletree, first welding bead is cleaned out before welding, it is first right during welding Welded on the inside of cylinder, then outside carbon plane back chipping, capping, during positioning, the twice longitudinal plate in adjacent cylinder, which is sewed on down, to be staggered 90 °, the weld seam that lateral loops are stitched to rare more than 50mm is overlapping, and the strengthening of welded seam in beginning and end region must not exceed 3mm.

Beneficial effects of the present invention are as follows:

1st, welding is closed up by vertical again after each segmentation first horizontal construction when the present invention builds lower component, building technology orderliness has Sequence, greatly improves efficiency of construction, and the jacket of lower component passes through steel-pipe pile, the first singletree, the second singletree, the 3rd stull The setting of bar and hound, the support steadiness that bottom is set up is ensure that, so as to ensure that the longtime running of offshore boosting station is tieed up Shield, and steel-pipe pile includes vertical portion and intilted rake, substantially increases the supportive of lower component, is not susceptible to Tilt.

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