Description
Technical field
The present invention relates to technical field of wind power generation, refer in particular to a kind of construction party of offshore wind generating partial installation
Method.
Background technique
China's oceanic area is vast, and offshore wind energy resource is abundant, and the potential using sea wind wind-power electricity generation is very big, but China
Wind energy on the sea develop later, Oversea wind power generation indicating China formally since the completion of Donghai Bridge marine wind electric field.
Offshore wind farm is the open sea environment that offshore is more than 10 nautical miles, mesh as a kind of new energy, at present country's addressing
There are mainly two types of modes for preceding offshore wind turbine installation, and one is use large-scale floating cranes directly to carry out integral hoisting,
Second is that using the dedicated large scale equipment of assembling.Since sea situation is severe, especially natural conditions pair such as construction area wind, wave, stream
No matter the influence of ship machine construction which kind of above-mentioned scheme is used, all had the disadvantage in that due to wind-driven generator entirety marine transportation
Center of gravity is high, and the risk that causes to tumble is big；And in transport, the ability of transport and hanging device is not only increased substantially, is also wanted
Integral installation buffer unit is considered in wind generator design to reduce the clashing and breaking rate of sea-freight and sea dress, thus caused marine big
The installation difficulty of type wind-driven generator is big.
In order to overcome the above problem, Chinese invention patent (CN101985917A) discloses a kind of offshore wind turbine
Tower crane is assembled in land, is refuted using the crane barge side of being hung to, then tower crane is mounted on by crane barge by partial installation construction method
After on pier and it is fixed on pier；After tower crane is installed on pier, sequence installs three section towers of blower, lifting
Blower host, wheel hub and blade；The tower that blower is unclamped using cohesion device is turned to upright position, withdraws cantilever crane and king-post,
Tower crane is lifted on transport barge with crane barge.Above-mentioned offshore wind turbine partial installation construction method, although reducing
Self weight, reduces costs, and facilitates the integral installation of tower crane, but due to the required precision of assembling height, causes to lifting
The requirement of equipment is also very high, and still depositing leads to the problem of reducing construction efficiency vulnerable to wave influence during installation.
Summary of the invention
For this purpose, technical problem to be solved by the present invention lies in overcome in the prior art Wind turbines installation vulnerable to sea situation shadow
Ring, the problem that causes construction efficiency low to provide it is a kind of influenced by sea situation small, guarantee that Wind turbines installation is steady to the full extent
The construction method of qualitative offshore wind generating partial installation.
In order to solve the above technical problems, a kind of construction method of offshore wind generating partial installation of the invention, described
Wind-driven generator is located on the cushion cap of blower foundation, wherein the wind-driven generator includes pylon and is located above the pylon

Anti-collision structure installation and cushion cap reinforcing bar, template and concrete structure are constructed；Step S4: it is utilized on the assistance platform
The suspender on the tower hoisting to the cushion cap and will first be installed, and then again lift the blower to the pylon
It goes up and is installed.
In one embodiment of the invention, the assistance platform uses jacket structure, whole spicing forming type.
In one embodiment of the invention, when the assistance platform is installed, in the lower end of the assistance platform, setting is anti-
Heavy reinforcing rod, and go deep into the anti-settling reinforcing rod in mud.
In one embodiment of the invention, auxiliary pile is installed at the node location of the assistance platform, and institute is installed
The method for stating auxiliary pile are as follows: be first inserted vertically into four auxiliary piles in the casing of four corner points of the assistance platform, pass through
Vibration hammer turns four auxiliary piles to designed elevation, promotes the assistance platform and assists to designed elevation and by described four
Stake is fixed in the auxiliary pipe casing, then hangs up and beats remaining auxiliary pile and remaining auxiliary pile is fixed in described sleeve pipe.
In one embodiment of the invention, four are inserted vertically into the casing of four corner points of the assistance platform
The method of auxiliary pile are as follows: auxiliary pile is sling by crane ship, the auxiliary pile is sequentially inserted into the assistance platform casing, so
Crane ship slings vibration hammer afterwards, makes the fixture of the vibration hammer close to the top of the auxiliary pile, and the fixture is caught in stake top
And clamp, finally start the vibration hammer auxiliary pile successively shakes and is sink to designed elevation.
In one embodiment of the invention, the assistance platform is promoted to consolidate to designed elevation and by four auxiliary piles
The method being scheduled in the assistance platform casing are as follows: after the assistance platform is promoted to designed elevation, in the assistance platform
Beam is shelved in insertion in through-hole on casing, and four auxiliary piles is made to be located at the lower section for shelving beam.
In one embodiment of the invention, the method remaining auxiliary pile being fixed on the assistance platform are as follows: in institute
It states equal aperture on remaining auxiliary pile and forms mounting hole, and the mounting hole on the remaining auxiliary pile is made to be directed at the assistance platform set
Through-hole on pipe, then so that the remaining auxiliary pile is fixed on the assistance platform across the mounting hole on corresponding beam of shelving
On.
In one embodiment of the invention, when the assistance platform is installed, the assistance platform is hung using crane ship
To the position for performing label in advance, make the assistance platform close to the starboard of station keeping ship, the center line on the assistance platform
When position is overlapped with the ship side outer center line of the station keeping ship, by slowly decentralization is high to designing after assistance platform leveling
Journey broke off relations after the assistance platform is stablized, subsequently into the auxiliary pile construction stage.
In one embodiment of the invention, the pylon includes positioned at the tower of bottom, above the tower
