Description
Technical field
The invention belongs to dredging and reclamation technical field, a kind of construction parties for pipeline of dredging under water more particularly to marine lifting
Method
Background technology
At present, Dredger Filling Engineering is constructed, the long-term aerial drainage of discharge opening, covers thick layer silt above pipeline under water
Mud, hardened through precipitation after a period of time, the soil body forms some strength, cause underwater line can not with normal mode by its
Act the water surface.
Existing construction method, being inflated using air compressor machine makes underwater immersed tube float, then the underwater line floated is hauled out and is applied
Work waters.After this method failure is implemented, begin to take on what the underwater immersed tube cooperation of station keeping ship system lifting rope auxiliary lifting was inflated
Method, concrete operations are as follows：
1st, it is first inflated using air compressor machine and excludes totally, to make to be filled by air in the depot siding by the underwater immersed tube internal water accumulation of the section
It is full；
2nd, a lifting rope is worn in its pole-climbing with a station keeping ship, after forming lock tube, is inserted in from the origin or beginning of underwater line
The underwater line hoists lifting rope by motor on station keeping ship, makes to drag underwater line thereon.
The reason of such operating mode underground pipelines can not normally rise out is analyzed, native thick soil is larger, and blank pipe line is silted mud drum first, burying
It encloses, without buoyancy；Second is that the soil body is hardened by precipitating for a long time, certain shearing strength is formed, integral strength is more than
Pipeline bears intensity, and lifting process is easily destroyed pipeline, cause pipeline that cannot reuse.
However, after being operated using the method that above-mentioned routine plays underwater line, preferable effect is not obtained.Through excessive
Analysis finds that main problem is as follows：
1st, covering mud layer is silt clay, and thickness is thicker, and the ballast above pipeline is excessive, and only input quantity is limited
Station keeping ship lifting strength is not enough to sling underwater line；
2nd, it cannot effectively slide to and lock the end of next group of pipeline on station keeping ship or anchor ship by dead weight with lifting rope, cause
Make station keeping ship during lifting, it is excessively high that upper one group of free end of pipeline acts the water surface, there are disconnected cable, touches and pounds the risk of ship machine, fixed
Position ship dare not be lifted by crane, therefore there are some potential safety problemss with excessive strand power；
3rd, the fracture of disconnected or flange port is easily hung in gum cover position by excessive power of hanging, and prevents pipeline or gum cover from repeating profit
With, and lifting rope rises and easily sludge discharge pipeline tube body and flange port is caused to scratch when dragging, and influences the follow-up use of pipeline；；
Once the 4th, the huge station keeping ship of input quantity, one side chartering is of high cost, on the other hand during the construction of this kind of method
Between long, inefficiency.
Invention content
The present invention for solve known technology present in technical problem provide a kind of construction is simple, raising working efficiency,
Reduce the marine construction method for lifting by crane pipeline of dredging under water of labor intensity, protection pipeline.
The present invention is adopted the technical scheme that solve technical problem present in known technology：
A kind of construction method of the underwater pipeline of dredging of marine lifting, it is characterised in that：The construction method includes the following steps：
1) initiating terminal of lifting, is set according to line layout position first；It will be remaining using air compressor in initiating terminal
The ponding of in-line is discharged, and makes pipeline interior full of air, and is sealed the both ends of pipeline using plug members；
2) lantern ring, is set in the initiating terminal of pipeline lifting, sheath, the lantern ring connection are enclosed with outside the lantern ring
Single lifting rope；
3) it, for the specific location of this clear and definite lifting rope, avoids and closes on the interference of dock vessels anchor hawser, lifting rope is from pipeline
After initiating terminal extension certain distance, every piece auxiliary rope of 5~8m systems, the auxiliary rope other end is ined succession buoy, in the appearance of buoy
Smear fluorescent material in face；
4), the lifting equipment of the other end connection anchor ship of the lifting rope；
5), the anchor ship moves ahead a distance along the initiating terminal that pipeline lifts by crane, and ensures that lifting rope forms one with pipeline
Angle；
6) anchor ship, is at the uniform velocity opened, pipeline is lifted by crane using the lifting equipment of anchor ship, lifting rope is by the mud on pipeline top
Layer is cut, and forms open mud groove, pipeline is detached with mud layer, with the traveling of anchor ship, seawater is along the mud groove of cutting
It pours into, makes buoyancy of the pipeline full of air by seawater, pipeline emerges；
7), after pipeline emerges completely, pipeline is drawn to the lifting on the bank, completing pipeline using equipment on the bank
Operation.
The invention has the advantages and positive effects that：Since the present invention is using above-mentioned technical proposal, has the following advantages：
1st, existing anchor ship or station keeping ship simply reequip, easy for construction, improvement expenses are low, and the time is short,
Material therefor saves, easy to operate.
2nd, lifting rope is connected into lantern ring, protection pipeline surface and pipeline link can be played when cutting the soil body below pipeline
The effect of flange protects tube body, improves secondary service efficiency；
3rd, this lifting rope is a plastic ties every 5 meters after extension certain distance at pipeline, and the plastic ties other end is ined succession
Buoy, buoy are smeared by fluorescent material, on the one hand can instruct to carry on construction work at night, on the other hand in the construction process by indicating
Lifting rope position can effectively avoid the interference of the objects such as underwater cable, improve construction efficiency, reduce unnecessary time loss.
4th, it is original using directly lifting by crane by the way of can not normally by pipeline mud extraction face, thereby result in largely by buried pipeline without
Method secondary use causes great waste.And use after this construction method by effectively changing soil structures, make pipeline all
Soil strength reduction is enclosed, then can pass through using conventional method, sludge discharge pipeline is made smoothly to rise out and is transported.
5th, entire cutting soil process does not have to pipeline is allowed to bear larger pulling force, especially to sebific duct, reduces pipeline and breaks
Bad probability falls below also in work progress security risk minimum, has greatly enhanced the efficiency and pipeline of pipeline
Recovery utilization rate.
