A kind of mounting process of floating-supported type offshore wind farm mounting platform of the present invention, the technique also include step 6, basis
The actual demand to stability, the spud leg being placed horizontally on hull is sling steady to increase in the positioning pipe for squeeze into mounting platform
It is qualitative.
A kind of mounting process of floating-supported type offshore wind farm mounting platform of the present invention, the technique also include step 7, installation
After stage+module, when workboat carries out drilling operation, the drilling rod inserted in steel pile casting has inner and outer tubes composition, high pressure gas
Body is passed through in the interlayer between inner and outer tubes, and inner tube is hollow pipe, and interior bottom of the tube is open design, and mud is in gases at high pressure
Enter under effect via interior bottom of the tube after inner tube by being squeezed at the top of inner tube by flexible pipe in the filtering ponds of hull, also set up on hull
There are sedimentation basin and multiple mud pits, the mud after the screen filtration in filter tank is pumped into sedimentation basin via pump one, sedimentation basin
It is connected between mud pit by pump two；Mud pit squeezes into mud in the gap between drilling rod and steel pile casting through pump three.
Compared with prior art, the beneficial effects of the invention are as follows：
Mounting platform of the present invention is only the steel construction piece suggested, transport is loaded to it using common towboat, reaches and specifies mesh
Ground after it is fixed, compared to routine self-propelled mounting platform, the present invention it is simple in construction, construction cost is cheap,
It is favorably improved the market competitiveness.

Embodiment
Referring to Fig. 1 ~ 10, a kind of mounting process of floating-supported type offshore wind farm mounting platform of the present invention, the technique
Include following steps：
Step 1, mounting platform is positioned on hull 3, mounting platform includes more vertically arranged positioning pipes 1.1, positioning
Connecting tube 1.2 is horizontally connected between pipe 1.1, fixing hole 1 is provided with the positioning pipe 1.1；And it is located at mounting platform
Spud leg 2.1 is plugged with positioning pipe 1.1 on four angles, fixing hole 2 2.2 is provided with spud leg 2.1, is spun on fixing hole one
1.3 and fixing hole 2 2.2 in bolt spud leg 2.1 is fixed in positioning pipe 1.1；Further, in step 1, installation is flat
Platform is shelved on the support member 4 on hull 3, and laterally disposed between hull 3 and mounting platform has more pile legs 2.1；
Step 2, hull 3 are navigated by water to destination with mounting platform, remove the bolt between spud leg 2.1 and positioning pipe 1.1 so that
Spud leg 2.1 sinks under Gravitative Loads；
Step 3, the loop wheel machine being installed on hull 3 sling vibration hammer and carry out vibration beating to spud leg 2.1 so that the bottom of spud leg 2.1
Hammer into mud；
Step 4, bolt screwed in into fixing hole 1 and fixing hole 2 2.2, so as to which spud leg 2.1 is fixed in positioning pipe 1.1；
Step 5, by ballast mode hull 3 is sunk so that hull 3 is separated with mounting platform, and hull 3, which rolls away from, rests in peace
By assembling platform；
Step 6, the demand according to reality to stability, the spud leg 2.1 being placed horizontally on hull 3 is sling and squeezes into mounting platform
Positioning pipe 1.1 in increase stability；
After step 7, mounting platform install, workboat carry out drilling operation when, insert steel pile casting in drilling rod have inner tube and
Outer tube is formed, and gases at high pressure are passed through in the interlayer between inner and outer tubes, and inner tube is hollow pipe, and interior bottom of the tube is open design,
Mud enters the filtering after inner tube by squeezing into hull 3 at the top of inner tube by flexible pipe in the presence of the gases at high pressure via interior bottom of the tube
In pond, sedimentation basin and multiple mud pits are additionally provided with hull 3, the mud after the screen filtration in filter tank is taken out via pump one
Enter in sedimentation basin, be connected between sedimentation basin and mud pit by pump two；Mud is squeezed into drilling rod through pump three for mud pit and steel protects
In gap between cylinder, so as to which the excavation operation of drill bit is lubricated and cooled using mud；
Compared with the mud of routine imports, conventional mud veclamation processing is carried out on workboat, so the same for specialty
Workboat for also need additionally to increase its displacement to there is enough space mud, undoubtedly add and be manufactured into again
This；And for this patent, hull 3 is that conventional towboat structure, low cost, and its main purpose are flat to tow installation
Platform, while extra reception mud veclamation utilizes, a ship uses, and reduce further its construction cost；
In addition：It should be noted that above-mentioned embodiment is only a prioritization scheme of this patent, those skilled in the art
Any change or improvement that member is done according to above-mentioned design, within the protection domain of this patent..
