Abstract
The invention relates to a method and a device for laying submarine cable, which is characterized in that, a plurality of gasbags connected by the connecting belt and the connecting pipe are coiled on the drawing drum, the gasbag drawing drum is provided near the cable drum in parallel, when laying the submarine cable, an air compressor is provided on the traction ship which tracts directly the cable and the gasbags, meanwhile, the air compressor inputs the compressed air into the gasbags, after the traction ship tracts the gasbags and the cable into the designated water field, the designated water body open the air inlet valve to exhaust, promote the cables into submarine pre-excavating cable chute, then close the valve to complete submarine cable laying. The invention has beneficial effects that inverse gasbags for laying submarine cable can reduce requirements for construction water area condition and weather condition, reduce effectively danger for damaging cable, reduce workload and labor intensity of the diver; when cable fault, the cables can be salvaged convenient for repairing without special equipment.
Description
Affiliated technical field
The invention belongs to a kind of power cable laying method and device, particularly a kind of submarine cable laying method and device.
Background technology
At present, known submarine cable generally is from laying ship a lot of air tubes of colligation to the cable the tractor tug, and the air of tyre cavity is put into cable in the submarine cable ditch that digs in advance (as shown in Figure 1) in being put gradually by the diver in specifying the waters.In the waters that The turbulent river crashes its way through in this way the time, thus can be also big because of the big water resistance of air tube volume, cable occurs and float from target or uppity phenomenon, wait for the environmental condition that is beneficial to construction so often stop work; If laying area current complexity in addition is such as running into whirlpool or when refluxing, cable also can coil, beat strand (stubborn fried dough twist) and damage; Because the used inner tube of a tyre is more during construction, need more diver's collaborative work, therefore compare difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of a small amount of increase cable size; thereby the air bag that reduces water resistance is used to replace original air tube; this air bag both can be used for laying; also can be used for salvaging cable; also can be used as a kind of gambeson that mechanical protection is provided and follow the submarine cable laying method and the device of submarine cable throughout one's life; to overcome the difficulty that existing submarine cable lays, guarantee construction period and quality.
To achieve these goals, the method applied in the present invention is: a plurality of air bags that connect by connecting band are coiled on the draw drum, each air bag inside communicates by tube connector and straight-through valve, when laying submarine cable, by direct trailing cable of tractor tug and air bag, in tractor tug trailing cable and air bag, cable is arranged in the groove of air bag; Air compressor machine is set on tractor tug, tractor tug air compressor machine in traction is imported compressed air by the air intake valve on the air bag in air bag, cable in tractor tug traction air bag and embedding air bag is behind the appointment waters, open the air intake valve exhaust by the staff, by laying requirement control exhaust velocity, and promote in the cable trough that cable enters water-bed excavation in advance, valve-off is finished submarine cable and is laid work; When needs are salvaged submarine cable, only need in air bag, to import compressed air and can finish salvage.
Above-mentioned air bag be shaped as U-shaped, in tractor tug trailing cable and U-shaped air bag, cable is arranged in the U-lag of air bag.
The present invention also provides a kind of submarine cable laying apparatu, constitute by tractor tug, cable hank, be characterized in: tractor tug is provided with air compressor machine, and at the other air bag draw drum that has been arranged in parallel of cable hank, the air bag on the draw drum is made of a plurality of air bags that connect by connecting band.
Also be provided with intake valve and tube connector on above-mentioned each air bag, each air bag communicates by tube connector.
Tube connector on above-mentioned each air bag is provided with straight-through valve.
Above-mentioned air bag be shaped as U-shaped.
The both ends of above-mentioned U-shaped air bag opening are provided with the flexible connection facility that is used to seal the U-shaped air bag opening.
The above-mentioned flexible connection facility that is used to seal the U-shaped air bag opening is the velcro cloth that is arranged on U-shaped air bag opening both ends.
The invention has the beneficial effects as follows: inverted U-shaped air bag is used for submarine cable lays, can reduce requirement, and can reduce the danger that damages cable effectively, reduced diver's workload and labour intensity construction waters regimen and meteorological condition; Not needing special installation just can salvage cable during cable fault is convenient to repair; A kind of gambeson of mechanical protection that provides also is provided follows submarine cable throughout one's life, its structure is also simple.

Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples, but this embodiment should not be construed as limitation of the present invention.
The present invention is made of tractor tug 4, cable hank 1, tractor tug 4 is provided with air compressor machine 5, at the cable hank 1 other air bag draw drum 7 (Fig. 2) that has been arranged in parallel, air bag on the draw drum 7 is made of a plurality of air bags 8 that connect by connecting band 8.2, each air bag 8 is provided with intake valve 8.1 and tube connector 8.3, each air bag 8 communicates by tube connector 8.3, and the tube connector 8.3 on each air bag 8 is provided with straight-through valve 8.4 (Fig. 3).
Embodiment (Fig. 2):
Be fixed on the bank or lay on the ship air bag draw drum 7 and cable hank 1 are in parallel, one end is fixed on the tractor tug 4, and air compressor machine 5 is linked to each other with the intake valve 8.1 of air bag 8 with gas pipeline 6, air bag draw drum 7 and cable hank 1 rotate simultaneously when starting on the tractor tug 4, cable 2 and air bag 8 are pulled simultaneously, at this moment by the artificial U-lag of constantly cable 2 being put into air bag 8, and the velcro cloth 8.5 of U-shaped air bag 8 openends overlapped, start air compressor machine and can carry out cable laying work waterborne, arrive slow exhaust when being scheduled to station, cable slowly sinks, and is shifted onto in the submarine cable ditch by the diver, the backfill cable trough, the work of laying is finished.
