Step 2, hull are navigated by water with mounting platform to destination, the bolt between spud leg and positioning pipe are removed, so that stake Leg sinks under Gravitative Loads;
Step 3, the loop wheel machine being installed on hull sling vibration hammer and carry out vibration beating to spud leg, so that spud leg bottom hammers into In mud;
Bolt is screwed in fixation hole one and fixation hole two by step 4, so that spud leg is fixed in positioning pipe;
Step 5, by ballast mode by Hull sinkage so that hull is separated with mounting platform, hull, which is driven out to, to be rested in By mounting platform.
A kind of mounting process of floating-supported type offshore wind farm mounting platform of the present invention, in step 1, mounting platform is shelved on ship On supporting element on body, and laterally disposed between hull and mounting platform there are more pile legs.
A kind of mounting process of floating-supported type offshore wind farm mounting platform of the present invention, the technique also includes step 6, basis The spud leg being placed horizontally on hull is sling and squeezes into mounting platform except the positioning pipe on four angles by the practical demand to stability To increase stability in outer positioning pipe.
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 being inserted into 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 bottom of inner tube is open design, and mud is in high pressure gas Enter after inner tube via bottom of inner tube by being squeezed into the filtering ponds of hull at the top of inner tube by hose under effect, is also set up on hull There are sedimentation basin and multiple mud pits, the mud after the screen to filtrate in filtering ponds 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 present invention are:
Mounting platform of the present invention is only the steel construction piece suggested, transport is loaded to it using common towboat, arrival refers to It is fixed after determining destination, compared to the mounting platform of conventional self-propelled, the configuration of the present invention is simple, construction cost are low It is honest and clean, help to improve the market competitiveness.

Specific 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:
Mounting platform is placed on hull 3 by step 1, and mounting platform includes more vertically arranged positioning pipes 1.1, It is horizontally connected with connecting tube 1.2 between positioning pipe 1.1, is provided with fixation hole 1 on the positioning pipe 1.1;And it is located at installation It is plugged with spud leg 2.1 in positioning pipe 1.1 on four angles of platform, fixation hole 2 2.2 is provided on spud leg 2.1, is spun on fixation Spud leg 2.1 is fixed in positioning pipe 1.1 by the bolt in hole 1 and fixation hole 2 2.2;Further, in step 1, pacify Assembling platform is shelved on the supporting element 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 with mounting platform to destination, 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 spud leg 2.1 Bottom hammers into mud;
Bolt is screwed in fixation hole 1 and fixation hole 2 2.2 by step 4, so that spud leg 2.1 is fixed on positioning pipe 1.1 It is interior;
Step 5 is sunk hull 3 by ballast mode, so that hull 3 is separated with mounting platform, hull 3 is driven out to stop By mounting platform;
Step 6, the demand according to reality to stability, the spud leg being placed horizontally on hull is sling and squeezes into mounting platform To increase stability in positioning pipe in addition to the positioning pipe on four angles;
After the installation is completed, when workboat carries out drilling operation, the drilling rod being inserted into steel pile casting has interior for step 7, mounting platform Pipe and outer tube are constituted, and high pressure gas is passed through in the interlayer between inner and outer tubes, and inner tube is hollow pipe, and bottom of inner tube is to open wide knot Structure, mud enter after inner tube via bottom of inner tube by squeezing into hull 3 by hose at the top of inner tube under the action of high pressure gas In filtering ponds, sedimentation basin and multiple mud pits are additionally provided on hull 3, the mud after the screen to filtrate in filtering ponds is via pump One is pumped into sedimentation basin, is connected between sedimentation basin and mud pit by pump two;Mud pit through pump three by mud squeeze into drilling rod and In gap between steel pile casting, to be lubricated and cool using excavation operation of the mud to drill bit;
Compared with conventional mud imports, conventional mud veclamation processing is carried out on workboat, in this way as It also needs additionally to increase its displacement for the workboat of profession to there is enough space mud, undoubtedly increases manufacture again Cost;And for this patent, hull 3 is that conventional towboat structure, low cost, and main purpose are to tow installation to put down Platform, while extra reception mud veclamation utilizes, a ship is multi-purpose, further reduced its construction cost;
In addition: it should be noted that above-mentioned specific embodiment is only a prioritization scheme of this patent, the skill of this field Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
