Abstract

An engineering ship for laying down underwater soft raft has the longitudinal reel driven by motor, a guide beam parallel to said reel, a slide plate at opposite side of said reel on deck and jointed to ship body via rotary axle, a buoy under said slide plate, and pull cable between the outside of slide plate and winder on deck and passing through the pulley on the top of a vertical pillar. A technology for laying down the underwater soft raft includes such steps as pulling the soft raft from reel via guide beam to slide plate, correcting ship position, putting down slide plate, releasing the soft raft while hanging the concrete blocks to it and filling sand in its sand tube, and slowly moving the ship backward.

Description

Engineering ship for laying down underwater soft raft and process for laying down underwater soft raft
Technical field
The present invention relates to a kind of under-water operation engineering ship and under-water operation technology, particularly a kind of engineering ship for laying down underwater soft raft and process for laying down underwater soft raft.
Background technology
Downstream in great rivers broadens owing to the river course at present, current slow down and cause the silt alluvial, thereby influence the unimpeded of river course, estuario as THE LOWER YANGTZE VALLEY deposits at this because of the broad silt of upstream that makes, influence the navigation of large ship, now adopt the method build wall under water that the current of marine outfall are flowed along drainage line, the method of wall improves water flow velocity by building under water artificially, thereby the alluvial of assurance silt is not deposited on the river course, but owing to be soft mud under water, need large tracts of land to lay the soft raft river bottom protection when building dike, existing method is to adopt manually soft raft pulled out top from the auxiliary vessel to be fixed on the bank slope, soft raft is bound little sandbag then aboard ship, outer moving by auxiliary vessel put into the bottom for one section one section with soft raft, the method efficient is low, and it is shallow to be used for water, the river that flow velocity is little, or the place of pulling in to shore, and because the warpage of soft raft when binding little sandbag and causing soft raft to transfer, make that the splicing gland of two soft rafts can't dock under water, above-mentioned process can't satisfy the depth of water, the large-scale construction that area is wide.
Summary of the invention
The objective of the invention is to solve and lay the problem that the river bottom protection soft raft mainly relies on artificial laying on the mud soft under water in the prior art.The present invention designs engineering ship for laying down underwater soft raft, comprise the auxiliary vessel hull, it is characterized in that: hull vertically has reel in the deck in ship structure upper edge, reel is by driven by motor, reel one side deck on the ship have one with the nose girder of the parallel placement of reel, by on the deck of hull edge slide plate is arranged at the reel opposite side, slide plate is connected with hull by rotating shaft, below the outside of slide plate floating drum is arranged, the outside of slide plate has drag-line to be connected with winch on the deck through the pulley on the column top on the deck.Utilize engineering ship for laying down underwater soft raft to carry out process for laying down underwater soft raft, it is characterized in that: the soft raft that will be installed on the reel is pulled out around nose girder half cycle post-tensioning to slide plate, the check and correction accommodation, put down slide plate, slowly unreel tube, the concrete interlocking block that is placed on the auxiliary vessel is connected on the soft raft, puts down soft raft through the slide plate entry; Charge sand in the sand tube on soft raft, move after auxiliary vessel is slow, until the software last person.Advantage of the present invention is rapidly and accurately soft raft entirely to be laid under water.
Description of drawings
Below in conjunction with drawings and Examples the present invention is elaborated,
Accompanying drawing is a structural representation of the present invention,
The specific embodiment comprises auxiliary vessel hull 1, it is characterized in that: 2 upper edge hulls vertically have reel 3 on hull 1 deck, reel 3 is driven by motor 4, reel 3 one side deck on the ship 2 have one with the nose girder 5 of reel 3 parallel placements, by on the deck 2 at hull 1 edge slide plate 6 is arranged at reel 3 opposite sides, slide plate 6 is connected with hull 1 by rotating shaft 7, floating drum 8 is arranged below the outside of slide plate 6, and the outside of slide plate 6 has drag-line 9 to be connected with winch 12 on the deck 2 through the pulley 11 on 10 tops of the column on the deck 2.Utilize engineering ship for laying down underwater soft raft to carry out process for laying down underwater soft raft, it is characterized in that: the soft raft that will be installed on the reel 3 is pulled out around nose girder 5 half cycle post-tensionings to slide plate 6, pulling out soft raft around nose girder 5 half cycles is when preventing that hull from moving, soft raft is to the impact of reel 3 under water, the displacement that to the friction force of nose girder 5 resist hull 1 by soft row's body this moment, proofread the accommodation then, put down slide plate 6, slowly unreel tube 3, the concrete interlocking block that is placed on the auxiliary vessel 1 is connected on the soft raft, puts down soft raft through slide plate 6 entry; Charge sand in the sand tube on soft raft, auxiliary vessel 1 moves after slowly, until the software last person.Owing in connection concrete interlocking block on the soft raft and the sand tube on soft raft, charge sand, put it into and to sink on the water-bed mud in the water, owing to below the outside of slide plate 6 floating drum 8 is arranged, therefore when putting soft raft, can guarantee the balance of hull, and the outside of slide plate 6 has drag-line 9 to be connected with winch 12 on the deck 2 through the pulley 11 on 10 tops of the column on the deck 2, when placing soft raft, can adjust the entry angle of slide plate 6 according to situations such as the depth of waters again, thereby guarantee the correctness of the position of soft raft entry.

Claims (2)

1, engineering ship for laying down underwater soft raft, comprise the auxiliary vessel hull, it is characterized in that: hull vertically has reel in the deck in ship structure upper edge, reel is by driven by motor, reel one side deck on the ship have one with the nose girder of the parallel placement of reel, by on the deck of hull edge slide plate is arranged at the reel opposite side, slide plate is connected with hull by rotating shaft, below the outside of slide plate floating drum is arranged, the outside of slide plate has drag-line to be connected with winch on the deck through the pulley on the column top on the deck.
2, utilize the described engineering ship for laying down underwater soft raft of claim 1 to carry out process for laying down underwater soft raft, it is characterized in that:
(1) soft raft that will be installed on the reel is pulled out around nose girder half cycle post-tensioning to slide plate, and slide plate is put down at the check and correction accommodation,
(2) slowly unreel tube, the concrete interlocking block that is placed on the auxiliary vessel is connected on the soft raft, put down soft raft through the slide plate entry; Charge sand in the sand tube on soft raft, move after auxiliary vessel is slow, until the soft raft afterbody.
