Description
Technical field
The invention relates to a kind of water conservancy construction device, particularly relate to a kind of device and method for shoal river dredging.
Background technology
China is streamy country, and water-borne transport is widely used in the communication of numerous domestic waters as the mode of transportation of low cost.But by the impact of the extraneous factor such as water velocity, works viscous flow, cause riverbed height to rise and fall, form shoal and deep trouth, river course Navigation capacity is restricted, and for ensureing navigation channel normal pass, needs to carry out desilting work to river course.Desilting: the mud depositing (river) end, river is blown and stirs into turbid water shape, utilize desilting equipment or flow away with river, thus playing the effect of dredging.This engineering bridge site is positioned at Yalu River tidal reach, and this river course, place bends, and tidal range is large, the trestle built and project subject structure play viscous flow in bending river course, cause riverbed silting to form shoal, affect the normal navigation of crane barge and fortune beam ship, the lifting of end bay steel box-girder cannot be carried out.Shoal: refer to the deposit in riverbed below the water surface.Due to the change of river bed water Flow Velocity, erosion and the sedimentation of current hocket, and therefore longitudinal bed profile of riverbed shoal is sinuous often, and the accumulation part that riverbed is formed is exactly shoal.
At present, domestic existing shoal channel cleanout mode mainly contains: adopt dredger desilting, the silt of amphibious excavator, reach and reduce riverbed absolute altitude, ensure the object of navigation.
1) dredger desilting: dredger, by means of the motion of water, carries out excavating and carry the earthwork under transfer water.It will make it loosening through machine cuts by soil layer under water, silt particle be mixed with water, forms certain density muddy water mixture, then by the vacuum sucking-off that dredge pump produces, then be transported to mud-dumping yard through mud pipe.Adopt dredger to carry out desilting and utilize high water mark, dredger moves into the place needing desilting, carries out the mud on excavator conveying riverbed, mud is delivered to auxiliary Flat boat, mud is transported to assigned address, stop desilting during low tide.Shortcoming is that dredger is marched into the arena costly, and needs desilting to assist sludge boat, and Secondary Transport silt is not convenient, and holistic cost is higher.
2) amphibious excavator becomes silted up: the Multipurpose dredger being applicable to land, hag face, marsh and shallow water operations environment.Running gear adopts multi-hull ship formula floating box structure and sealing box-shaped creeper tread, can walk safely and operation at mud and the water surface.The overlength working arm strengthened, efficiently slew gear, can carry out amphibious digging operation, its shortcoming needs auxiliary ship to carry out storage outward transport to the silt excavated out, then have plant equipment to the silt secondary unloading on ship, the auxiliary big machinery needed is more, and integral construction cost is higher.
As known from the above, mainly there is following shortcoming in prior art:
1, adopt heavy mechanical equipment, costly, the engineering turnover field device amortization charge relatively less for desilting amount, the duration is shorter is larger in turnover field.
2, use auxiliary supporting machinery more, construction cost is higher.
3, the silt dug out needs Secondary Transport, unfavorable for energy-saving and emission-reduction.
Thus, the present inventor relies on experience and the practice of being engaged in relevant industries for many years, proposes a kind of device and method for shoal river dredging, to overcome the defect of prior art.
