Abstract
The present invention discloses cylindrical silt dredging device for a marine dredger. A cylinder for containing and dredging silt is in a cylinder body which is made of steel, and the cylinder body is provided with a top cover plate and is not provided with a bottom; two to four water discharging ventilation holes which are provided with sealed switch cover plates are arranged on the top cover plate of the cylinder body, and the sealed switch cover plates are opened and closed through ropes. A pressure rod and a lifting rope are also arranged on the top cover plate of the cylinder; in addition, two to four water pumping and injecting holes can also be arranged on the top cover plate of the cylinder. Four to sixteen interlayer through holes are evenly arranged outside a cylinder wall along the circumference; the upper parts and the lower parts of the through holes are communicated, and both ends of the through holes are opened. The present invention is suitable for dredging soft clay, hard clay, tight sand soil and other soil of various types, and has the advantages of high silt dredging efficiency, large disposable dredging depth and little influence on environment.
Description
Technical field
The present invention relates to the silt dredging device that a kind of seagoing dredge is used.Belong to the sludger in the dredging works field.
Background technology
At present, the silt dredging device that seagoing dredge is used has four kinds of forms, is respectively grab type, strand suction formula, rake suction formula and chain-bucket.Grab type is applicable to digs mud soil, and strand suction formula, rake suction formula and chain-bucket are applicable to and dig stiff clay and sandy soil.
Grab type is got mud for the interval property, by the defeated mud of barge.It is got mud side's amount maximum at every turn and is no more than 8m
3,, also because the shape of grab bucket limits, increase it and get earth volume and have any problem in addition because grab bucket sinks in the earth by deadweight.
Strand suction formula and rake suction formula are for fetching earth continuously, by the defeated mud of pipeline; Chain-bucket also for fetching earth continuously, can also can be failed mud by pipeline by the defeated mud of barge.Their soil extracting efficiency is higher, and the degree of depth is less but it fetches earth at every turn, in the time of digging darker dirt bed, needs repeatedly stage excavation, back and forth moves ship, influences efficient; Twist suction formula and rake suction formula in addition when getting mud, have a large amount of water to be taken away simultaneously, it is bigger to consume energy; Twist suction formula and rake suction formula in addition when getting mud, do not taken away after having a large amount of earth to be twisted pine or rake pine, when trend, these loose earth are taken away by trend, and the one side contaminated environment may make also on the other hand to be back-silted in the place of having been dug like this; Have when throwing mud point a little far again, when the defeated mud of pipeline is inadvisable, transport after needing on barge, to filter, like this to the pollution of environment with the problem of back-silting can be more serious again apart from dredging.
Therefore, it is stronger to be necessary to develop compliance, efficient height, the silt dredging device that the little seagoing dredge of ambient influnence is used.
Summary of the invention
The cylinder silt dredging device that the object of the present invention is to provide a kind of seagoing dredge to use, this silt dredging device have that applicability is wide, efficient is high, characteristics little to ambient influnence.
For achieving the above object, the present invention is realized by following technical proposals: the cylinder silt dredging device that the seagoing dredge that adopts steel plate to make is used, it is characterized in that, the cylinder that dress is got earth is the cylindrical shell of the no end that lamina tecti is arranged, on its lamina tecti, be provided with the drainage ventilation hole of 2 to 4 band enclosed switch cover plates, also establish 2 to 4 drawing water and water injection hole of linking to each other with pipeline in addition, on the girt strip of cylinder top cover plate, connect press rods and play hanger rope, 4 to 16 up/down perforations are evenly arranged along circumference in the barrel outside, the interlayer through hole of open at both ends, the lateral wall inward at both ends side that constitutes the interlayer through hole is bent to concordant with cylinder inner wall.
Above-mentioned drum diameter and highly be 1m to 6m.
The enclosed switch cover plate in the drainage ventilation hole on the above-mentioned cylinder top cover plate is realized the opening and closing operation by cable.
Superiority of the present invention is: the cylinder silt dredging device that seagoing dredge is used, be applicable to take soft or hard clay, closely knit sandy soil and other various types of earth, and get mud efficient height, disposable to dredge deep degree big, little to ambient influnence.
Description of drawings
Below in conjunction with accompanying drawing the present invention is illustrated.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is Fig. 1 vertical view.
1 is the tube lamina tecti among the figure, 2 is barrel, 3 is the outer wall of tube side interlayer through hole, and 4 is drainage ventilation hole and enclosed switch cover plate, and 5 for drawing water and water injection hole, 6 is press rods, 7 is the girt strip of lamina tecti, and 8 has been hanger rope, and 9 is the interlayer through hole, 10 is the cable of switch draining vent cap plate, and 11 for connecting the pipeline that draws water with water injection hole.
The specific embodiment
One embodiment of the invention is as follows: the cylinder silt dredging device that seagoing dredge is as depicted in figs. 1 and 2 used, its barrel dliameter are 4.0m, the high 5.0m of tube, and volume 62.8m fetches earth in the tube
3The tube lamina tecti is provided with the drainage ventilation hole of 4 diameter 0.5m, 4 diameter 0.2m draw water and water injection hole, barrel is provided with 10 interlayer through holes, each interlayer through hole is along the wide 0.3m of tube Zhou Fangxiang, thick 2cm, the tube lamina tecti is provided with girt strip, plays hanger rope and press rods and is connected on the girt strip of a lamina tecti.
This cylinder silt dredging device course of work is as follows: open the drainage ventilation hole on the lamina tecti, on the press rods of tube lamina tecti, exert pressure, cylindrical shell is inserted in the earth, close the drainage ventilation hole on the lamina tecti then, apply lifting force, cylindrical shell is sling, earth will together be sling with cylindrical shell in the tube, with soil in cylindrical shell and the tube hang forward honey barge ship top to after, open the drainage ventilation hole on the lamina tecti, earth will fall down from cylindrical shell and drop in the honey barge ship in the tube.Be inserted in the earth difficulty if cylindrical shell depended on pressure bar is exerted pressure, or the earth difficulty that from cylindrical shell, drops out, then can by on the tube lamina tecti draw water and water injection hole comes work.When being inserted into cylindrical shell in the earth, close the drainage ventilation hole on the lamina tecti, when exerting pressure with press rods, from draw water and water injection hole to extracardiac pumping, a tube external and internal pressure difference that produces by drawing water is inserted into cylindrical shell in the earth; When earth does not drop out behind the drainage ventilation hole on opening a lamina tecti, then close the drainage ventilation hole from cylindrical shell, by draw water and water injection hole in tube, annotate water under high pressure, an interior soil body is moved downward, behind the soil body setting in motion, open the drainage ventilation hole again, the soil body will drop out in the tube.
Interlayer through hole on the barrel be in the process that fetches earth with soil in cylindrical shell and the tube when slinging, the water of the cavity that filling cylindrical shell bottom forms therefrom flows through, and to prevent the excessive absorption affinity of generation between tube bed mud soil, can reduce lifting force like this.
