The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, a kind of free floating suction dredge(r) bow flushing device, it comprises free floating suction dredge(r).Described bow flushing device comprises that the bow of trussed construction rushes frame, and bow rushes frame main structure material and adopts the 16mm steel pipe, and bow rushes frame width 8m, dredging depth 0-4.5m.Described bow rushes chord position in free floating suction dredge(r) stem 8, and bow rushes that an end and the stem 8 of frame is hinged, and the other end head that bow rushes frame is provided with lifting pulley 7, and this lifting pulley 7 links to each other with hoister winch 1 on the free floating suction dredge(r) stem 8 by lifting steel wire 4.Stem 8 is provided with door-shaped hanging bracket 3, is fixed with leading block 2 on door-shaped hanging bracket 3 crossbeams, and described lifting steel wire 4 passes leading block 2 and links to each other with hoister winch 1.Hoister winch 1 and leading block 2 is used for that bow is rushed frame and transfers to a bow of transferring of working depth and rush frame 10 and work the rise position bow that rises to operational configuration and rush frame 11.Described bow rushes the frame front end and is provided with some bath nozzles 14, and bath nozzle 14 links to each other with the high-pressure flush pump by water spray rubber tube 6, and bath pressure can reach 6-7bar.The bath nozzle is that high molecule nano material is made, and has intensity height, wear-resisting characteristics.Described bow rushes the frame front end and also is provided with mud suction mouth, and mud suction mouth links to each other with dredge pump in the cabin by the suction mud rubber tube 9 of caliber 400mm.
The job practices of above-mentioned free floating suction dredge(r) is that free floating suction dredge(r) 13 reduces the speed of a ship or plane before arriving the works area, when arriving shallow district, controls accommodation adverse current construction.Manipulation hoister winch 1 is transferred bow and is rushed frame to the water surface, starts first and restarts the high-pressure flush pump in the cabin behind the dredge pump, continues to transfer bow again and rushes frame to the position of transferring that contacts the mud face, begins to carry out bow punching construction.Break ground by high-pressure flush, bow rushes frame mud suction mouth suction mud and enters spoil hopper by the dredging piping, the precipitation stowage.Observe at any time and suck concentration of hydraulic mixture, when concentration of hydraulic mixture descends, can continue to transfer bow and rush frame.When the mud layer of need dredgings is thicker, answer construction in layer, be preferably 1～1.5m and be divided into one deck.According to construction experience, layering is too thick, and mud layer can cave in and rush frame mud suction mouth back to bow, impact dredging effect.The bow punching is constructed width generally and bow is leapt high presses the pressure influence scope of bath suitable, therefore, the works area should be divided some by harrowing suction stem punching construction width, and overlap joint is arranged mutually between every itemize.It is each along the itemize adverse current of the dividing bow punching construction of reaching the standard grade that rake is inhaled ship.After every layering was finished, shorter such as grooving, rake is inhaled ship need not turn around the following current of falling the groove to next bar starting point, repeated to carry out bow punching construction into point.Longer such as grooving, should adopt tune extremely newly to starting point, the bow that advances a little to reach the standard grade punching construction.Construct complete after, the bow that hoists rushes frame and breaks away from the mud face, closes the high-pressure flush pump.Bow is rushed frame put into water, dredge pump remains in operation a period of time in the cabin, prevents that to suck clear water silt from stopping up dredging tube.Dredge pump in the closing chamber promotes bow and rushes the frame water outlet to rising the position afterwards.
In dredging works, under the very shallow working condition of the depth of water, adopt free floating suction dredge(r) bow punching stowage job practices, to compare with traditional job practices, dredging efficiency is higher, and the engineering time shortens greatly, and the mud surface evenness is fine after the construction.The use Multi-beam Echosounding System showed that the works area does not hinder the shallow point of boat after above-mentioned engineering was finished.
Inhale the traditional lower rake stowage job practices of ship if adopt rake, in view of the depth of water in the navigation channel very shallow, must use first grab dredger (or other ship type dredge boat) in advance dredging in the navigation channel to be inhaled the condition that ship can enter construction to harrowing from boat, so efficient is extremely low, the duration is very long, expense is also large.Not only guaranteed construction quality, also saved construction cost, shortened the construction period, effectively solved this problem and adopt the rake suction stem that certainly navigates to rush the stowage system construction.Show that by the application of the utility model free floating suction dredge(r) bow flushing device in above-mentioned engineering this construction is huge in the effect of cruiseway dredging works, social benefit is remarkable, and application prospect is good.
