Compared with prior art, the beneficial effects of the present invention are, two-shipper group hydraulic type dredger provided by the invention,
During construction, driving device is controlled by control device, water injector is accuracy moved into harbour bottom according to preset path
The predetermined position of portion's mud for clearance significantly reduces difficulty of water injector during dividing into, and then effectively mentions
Construction rate of water injector during dividing into has been risen, while having ensured the accuracy that water injector is divided into；Meanwhile passing through spray
Seawater is directly sprayed onto harbour bottom by water installations in a manner of high pressure, to carry out impacting with high pressure to mud for clearance, and then will
It is clear to improve mud to the workload in the sea, on the one hand significantly reduced in the mud scale removal process of harbour for the mud refunds
On the other hand the cleaning quality of harbour mud cleaning is effectively promoted in the efficiency of reason.
Especially, two-shipper group hydraulic type dredger of the invention, by control device according to harbour bottom position for clearance
Concrete condition calculate separately preset angle of the water injector to the mud of predetermined position in scale removal process under its respective conditions
Degree and default pressure have further speeded up the rate and cleaning quality of mud cleaning.

Predetermined angle β when water dispenser structure is sprayed water with high pressure, adjusts according to silt density.Wherein, in the first seawater and silt density section,
In 1.20~1.30g/cm3In density range, 1.20~1.30g/cm3Density belongs to the mud less stage, at this stage seawater
Mud is less, sets a biggish water spray angle at this time, that is, the angle of water outlet is more approached with sea level direction, is spraying
When penetrating high pressure water, since mud is less, the recoil strength due to spraying high pressure water that entire hull is subject to is smaller, and hull will not be made horizontal
It moves, hull can keep rinsing the state of mud in metastable position.Wherein, in the second density section, 1.30~
1.45g/cm3In density range, 1.30~1.45g/cm3Density belongs to the mud general stage, and seawater mud is suitable at this stage
In, for the ideal stage for removing mud, a moderate water spray angle is set at this time, that is, the angle of water outlet and sea level
Direction is close to 45 °, and when spraying high pressure water, water jets under high pressure generates pushing away for downward pressure and horizontal direction to mud and seawater
Power is moved, downward pressure is superimposed the mud of the seawater of certain depth downwards, and active force can be sufficiently applied to certain depth
Mud, meanwhile, tractional force makes mud mobile, reaches optimal flushing effect.Wherein, in third density section, 1.45~
1.60g/cm3In density range, belong to the state of severe mud in this process, when water column sprays, if having with horizontal plane smaller
Angle, can be generated due to recoil strength certain traversing, influence dispels effect.Also, the mud in the stage has biggish close
Degree, needs to make the impact force of vertical direction sufficiently large, so that mud sufficiently dissipates.
