Description
Technical field
The present invention relates to a kind of jacket construction techniques, more particularly, to one kind to jacket and piling bar in offshore engineering
The technique overturn, installed.
Background technology
Currently, need to install jacket in advance in the work progress such as ocean wind-powered electricity generation, jacket is bulky, weight pole
Weight not only loads and unloads ship difficulty if being transported using vertical mode, and the capacity of anti-storm in shipping process is very poor, is unfavorable for applying
Work safety；And jacket it is in place after also need to installation piling bar and be fixed, it is long that the piling bar of large jacket often reaches rice up to a hundred,
Therefore can only carry out it is laterally disposed transported afterwards above deck, overturning is to vertical after shipping to destination, in the process of overturning
It is middle to need to be fixed to facilitate loop wheel machine operation using the stake device that rises for filling in piling bar head；But play the installation process of stake device
In nowadays lack effective lead-in mode, often carried out by the way of impact, to less than inefficiency, and safety,
Working specification is poor.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of transport, the extremely convenient jacket constructions of operation
Technique.
The object of the present invention is achieved like this：
A kind of jacket construction technique, it is characterised in that：The technique includes following steps：
Step 1, barge drive jacket to target location, and are equipped with slideway on the deck of barge, and jacket is laterally put
It is placed on the slideway；
Step 2, barge ballast tank start to load ballast water so that barge tilts 2~3 °, and the stub end of jacket
It is located at rising end positioned at decline end, small head end, meanwhile, the barge is provided with returning face plate in the stub end of jacket, the overturning
It being hinged with the deck of barge in the middle part of the bottom surface of plate, the half of returning face plate is suspended on outside barge, the other half is shelved above deck, and
The top surface of returning face plate is flush with chute surface；
Step 3, jacket slide onto on returning face plate downwards, distinguish towed vessel by cable on the four of jacket angle at this time
It holds, when the center of gravity of jacket slides onto the free end of overturning meal, returning face plate overturning drives jacket to enter water；Whole process is kept away
Exempt from jacket and grazing occurs with deck end；
The small head end that step 4, loop wheel machine lift by crane jacket is begun to ramp up, and disengages two towboats being connected with the small head end of jacket
Cable, while rising, the ballast tank on the stub end of jacket loads ballast water, until the vertical rigging out of jacket
Rear tube frame stub end disconnects the cable with two towboats；
Piling bar is lifted to flip bit by step 5, and piling bar is shelved on and turns on a device, this turns over a device and is articulated with deck for one
Flip piece on tail portion is provided with the U-lag being embedded in for piling bar on the top surface of the flip piece；One is provided on the side wall of piling bar to wear
Hole, the head of a rope have been connected to the head of stake device after perforation, and the tail portion of the rope is connected to volume after a fixed pulley
Raise machine；
Step 6, hoist engine work, have driven stake device to be entirely insertable in the head of piling bar by rope, play stake device and are passed through height
It is connected with piling bar realization after pressing gas expansion, then disconnects rope；
Dovetail on the end of the chain wound in step 7, hoist engine is hooked in the tail portion of piling bar；Hoist engine work,
Loop wheel machine is lifted by crane to playing a stake device, and piling bar is overturn by horizontal cross to vertical vertical under the action of turning over device；
Step 8, loop wheel machine drive vertical piling bar to be inserted into the piling bar hole of jacket by playing stake device；Piling bar is in gravity
A device, which is played, after the distance of lower sinking one end is detached from piling bar；
Step 9 repeats step 5~8, until being inserted into all piling bars in the piling bar hole of jacket.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention carries out ballast to barge during jacket installation and handles so that sliding jacket after its inclination, not only
Operating efficiency is improved, and is avoided to jacket grazing in morning；Meanwhile in the lifting switching process of piling bar, utilizing rope
The mode of traction has been packed into stake device, avoids and causes to damage to playing stake device and piling bar, and operation is convenient, safer reliable.
