Description
Technical field
It is especially a kind of for marine jacket-type wind the utility model relates to a kind of marine wind electric field construction equipment
The control platform of machine foundation construction.
Background technique
Currently, there are two development trends for marine wind electric field construction.Developed first is that it builds the depth of water from intertidal zone to shallow sea, example
As Guangdong Province is being built or the projects awaiting construction depth of water reaches 30-50m in recent years；Second is that the single-machine capacity of blower constantly increase and unit by
Step enlargement.This certainly will propose new requirement to the basis of offshore wind farm unit, and the Wind turbines used have been put at present
Base form has single pile formula, high-rise pile cap formula, gravity type, negative pressure barrel type, jacket-type, and wherein jacket-type basis is due to structure
Simply, securely and reliably, speed of application is fast, required construction equipment requires lower, the wind power plant project of neritic province domain was most in recent years
Using quadrangle jacket-type blower foundation.
Jacket-type blower foundation is a kind of steel structure frame, which mainly consists of two parts, first is that jacket,
Usually triangle, quadrangle or hexagonal are welded with conduit on each angle；Second is that steel-pipe pile (i.e. foundation pile), for jacket is fixed
On sea bed, and bear the load transmitted by jacket.There are two types of the connection types of jacket and foundation pile, and one is steel-pipe piles
Conduit on jacket is squeezed into subsea strata；Another connection type is steel-pipe pile first to be squeezed on sea bed, then will lead
Pipe support end is inserted into foundation pile.Two kinds of connection types require to pour into the annular gap between steel-pipe pile and jacket conduit
Jacket and steel-pipe pile are connected into an organic whole, form the basis of wind power generating set by special slurry material.
Using a Under Pile top mark high position 10~20m below the water surface of second of connection type, jacket installation contraposition is equal
It carries out under water.Design requirement stake top the relative position error < 50mm, there are no similar engineering precedents at home for this.
The foundation pile of underwater jacket installation uses pile driving barge piling construction, and stake top position deviation is larger.The depth of water is deeper, sea situation
Under conditions of poorer, the pile position deviation of pile driving barge pile sinking is bigger.During at sea driving piles, since construction area is wide, work surface
Greatly, construction environment and weather conditions are poor, use GPS-RTK measuring technique according to conventional positioning method, stake position error is only capable of reaching
≤300mm.After the completion of pile sinking, about high mud extraction face 10m at the top of foundation pile is in free end state, in external forces such as wave, ocean currents
Under, stake top can be continuously in upset condition.If not taking special construction technology and control measure, stake top the relative position error
It is unable to satisfy the requirement (< 50mm) of design.
The utility model is constructed for high-precision jacket-type blower foundation and is researched and proposed, and has important practical significance
And social benefit.
