A kind of offshore wind farm High-Rise Pile Cap Foundation docking system and construction method
Technical field
The present invention relates to marine berthing cushion cap technical equipment technical fields, more particularly to a kind of offshore wind farm high-rise pile cap
Basic docking system and construction method.
Background technology
With the fast development of wind generating technology, the land wind power plant developed and used is fewer and fewer, and offshore wind farm
Exploitation is increasingly taken seriously.Basic facilities of the offshore wind farm crew base as offshore wind power development, early period build and
Ship collision problem is inevitably encountered during later stage O&M.Certain protection can be taken for ship collision problem to arrange
It applies to reduce the active force that base support structure is subject to, to reduce damage of the ship to support construction.Currently used method
It is that ship part is leaned in setting in base support structure, reduces direct impact force etc. of the ship to foundation structure.
Docking system in the prior art is mainly by parts such as U-shaped ring, rubber spring, erosion control anchor chain, impingement baffle and cat ladders
Composition.The construction method of the program:When concrete bearing platform pours, pre-buried 4 U-shaped rings are distinguished in the upper and lower part of cushion cap,
In pre-buried 2 bolts in cushion cap lower part.The components such as outside impingement baffle and cat ladder assemble integral, the external entirety of lifting on the coast in advance
The top impingement baffle of structure, berthing device is connect by erosion control crab bolt with U-shaped ring, and lower part passes through impingement baffle anchor chain and U-shaped ring
Connection.The rubber spring bolt pre-buried with cushion cap lower part is connect when ship berthing, and less ship rushes blower foundation
Power is hit, good cushioning effect is played.However there are shortcomings, such as the entire vertical lotus of rubber fender berthing device for the system
Load mainly carried on a shoulder pole by impingement baffle bearing, fender is larger in the displacement space of erosion control board shaft, and fender have below foundation platform it is longer
Cantilever segment(6.4m), lateral force poor performance, appearance causes fender lateral tension damage etc. to ask due to berthing ship heaving pile
Topic.Cat ladder reinforcing bar selection such as goes wrong, the problems such as being susceptible to reinforcing bar deformation, be broken.

The first joint steel pipe 7 that steel pipe 5 and the hoop component 6 weld.
Further, the cushion cap built-in fitting 4 be 8 pieces and point upper layer and lower layer be embedded in advance 1 top of the concrete bearing platform with
And lower part, it is described by ship steel pipe 3 be 4;Described in 4 by 3 respective top of ship steel pipe respectively with horizontally disposed second joint steel pipe 8
It is fixedly linked, every uses Welder with the upper and lower 2 pieces cushion cap built-in fittings 2 by third joint steel pipe 9 respectively by ship steel pipe 3
Skill is fixedly linked.The cushion cap built-in fitting 2 is square steel plate.
The bollard 4 be more, and from top to bottom be horizontally disposed with after respectively with described in more lean on 3 stationary phase of ship steel pipe
Even.4 both ends of the bollard have been respectively fixedly connected with bollard sealing plate 10.The bollard 4 leans on 3 junction of ship steel pipe with described
It is provided with horizontally disposed stiffener plate 11.The cat ladder 12 is vertically arranged and in the middle part of the berthing member.The coagulation
1 top of native cushion cap is embedded with multiple platform connection built-in fittings 13, and multiple platform built-in fittings 13 are connected with steel platform 14.
The docking system is mainly by leaning on the part such as ship steel pipe, joint steel pipe, cat ladder, anchor ear and cushion cap built-in fitting to form.It should
The construction method of scheme:When concrete bearing platform pours, pre-buried 4 blocks of square steel plates are distinguished in the upper and lower part of cushion cap.By ship
Pre-assembly is integral on the coast for component, after lifted.Outrigger is first installed, outrigger is lifted again after the completion of reinforcing by ship when lifting
There are muscle hole is worn at overhanging 1.4 meters of component outrigger, fining twisted steel passes through perforation muscle to be connected with berthing member lifting lug hole, then
Suspension hook is slowly loosened, makes fining twisted steel stress, while being held with the chain block of 2 25t.Berthing member position is surveyed after stablizing
The position deviation of its position and built-in fitting is measured, then uses chain block(Up and down, longitudinal)And fining twisted steel(Left and right)To leaning on ship structure
Part position is finely adjusted, and requires progress site welding, berthing member pre-buried with berthing member according to construction drawing after location determination
Part welding completes recession chain block and tears outrigger open.
To improve the stability of docking system, two layers of support construction being connect with steel-pipe pile is set in cushion cap lower part.Upper layer
Anchor ear measures anchor ear at a distance from berthing member junction, then cuts steel pipe and open cut, be welded to connect steel after installation is complete
Pipe.
The connection of system provided by the present application, berthing member and concrete bearing platform is bolted by impingement baffle makes steel weldering into
Connect, impingement baffle makes Φ 406mm erosion control steel-pipe weldings into and forms, overall stability is very good, can meet Fan Equipment debugging, operation
It is needed for a long time with service work.Put into operation rear all right, novel docking system structure stress fully met design want
It asks, reduces the maintenance cost of later stage docking system.Docking system lower cantilever section increases embraces with what neighbouring steel-pipe pile was connected
Hoop, and be connected with erosion control steel pipe, it realizes that whole system is interconnected and fixed, erosion control steel pipe is avoided to play pendulum, enhancing berthing system
System lateral force performance.3 bollards are respectively set in docking system both sides from top to bottom, and can meet ship under different water levels is
Cable and berthing requirement.
