Description
Technical field
The present invention relates to offshore wind farm fields, and in particular to a kind of mobile surely stake platform and its construction technology.
Background technique
China possesses the coastal waters wind energy resources of very abundant, and Oversea wind power generation development prospect is wide.China coastline is about
For 18000km, coastal area is the load center of China's electricity consumption, and offshore wind farm has sufficient wind energy resources and the advantage of scale,
Have preferable access conditions, is suitble to the marine wind electric field of construction effective use wind energy.But the construction of current offshore wind farm exists
A series of risk: specific investment cost is at high cost, and the basis of marine wind electric field, the access costs such as power grid and installation are all much higher than
Land project；Constructional difficulties are big, and requirement of the operation on the sea to construction equipment is very high；To the requirement of offshore wind turbine q&r
It is high.According to the prospect of the Oversea wind power generation in current China and the whole world, the construction of marine wind electric field can effectively reduce cost,
There must be specialized offshore construction equipment.
My company investigates the design scheme and arrangement and method for construction of domestic and international offshore wind farm.From Preliminary design to construction drawing design rank
Section is constantly optimizing scheme, and foundation pattern originally is from five pile leader of pile leader frame-tri- frame of high-rise pile cap-- single pile base
Plinth-is significantly reduced costs without transition single-pile foundation, the optimization of each step in the case where ensuring safe and reliable, but
Difficulty of construction constantly increases.No transition single-pile foundation requires highest to pile sinking verticality, it is necessary to it controls within 3 ‰, when
When European countries offshore wind farm single-pile foundation all using there is a transition single-pile foundation, the effect of transition is mainly to foundation pile
Perpendicularity deviation in pile sinking is more than 3 ‰, is adjusted correction, it is ensured that the levelness of flange meets technical requirements, external
Sinking apparatus be all made of jack up leg platform ship and carry out steady stake, pile sinking, the degree control emphasis of pile sinking is in steady stake work
Skill.And only leg platform " China's electricity 1001 " hoist tonnage (700 tons) domestic at that time cannot fully meet requirement, and hand
It is continuous incomplete.In the case where supporting leg ship is limited, we must study other schemes to solve the problems, such as steady stake pile sinking.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of mobile steady stake platform and its construction technologies.
The technical solution adopted by the present invention is that:
A kind of mobile steady stake platform, the steady stake platform is in concave shape, and the steady stake platform includes auxiliary pile and support rod, institute

Mode lift by crane, crane ship side board is against after lifting, and tied steady stake platform semi-finished product with crane ship with wirerope, then led to
The method for crossing GPS positioning adjusts accommodation, is overlapped the Longkou center of steady stake platform semi-finished product with design engineering pile center,
Steady stake platform semi-finished product are placed on sea bed face, the positioning of steady stake platform is completed, then crane ship by four auxiliary piles according to
Cornerwise principle is successively sling and is inserted on sea bed, lifts by crane vibration hammer after the completion of pitching pile, vibration hammer slowly clamps auxiliary pile slightly
It is micro- pull up after again insertable into, be then turned on when relatively stable vibration hammer carry out pile pulling pitching pile until no drilling depth；
B, it the promotion and fixation of steady stake platform: measures the elevation location of steady stake platform and marks, then mentioned with crane ship
Steady stake platform semi-finished product are risen to marked locations, are finally welded auxiliary pile and the welding of steady stake platform semi-finished product using reinforcement steel plate
It is fixed together；
C, the construction of engineering pile and verticality adjustment: being risen engineering pile using crane ship and lift up into the Longkou among steady stake platform, under
Stake is then adjusted the verticality of engineering pile by correcting cylinder, and adjustment, which is finished, carries out steady stake and pile sinking, work for engineering pile
Auxiliary pile and steady stake platform semi-finished product are successively removed after journey pile driving construction.
Further, the method for the GPS positioning in step a, specific steps are as follows: steady stake platform semi-finished product lifting
Before, crane ship, in design engineering pile near center location, lifts by crane two after steady stake platform semi-finished product according to boat-carrying GPS coarse positioning
GPS rover station is fixed on corresponding ship side position, and the straight line that two GPS rover station centers are constituted is parallel with ship side outer, marks
Vertical and horizontal score line then commands crane ship to adjust accommodation, so that the center of steady stake platform semi-finished product and design engineering
The center of stake is overlapped, and tightens anchor hawser, steady stake platform semi-finished product are placed into sea bed face.
The beneficial effects of the present invention are: 1, save the time, shorten the construction period: using the steady stake platform of movable type in the present invention,
A working day is lacked in construction of the construction of each position compared to leg platform；2, remarkable in economical benefits: the movement in the present invention
