Description
Technical field
The present invention relates to a kind of harbour sludge treatment device and processing method thereof, belong to port and pier technical field.
Background technology
Harbour also exists Sediment Siltation problem more at large.Often back-silt after the excavation of harbour, need to come with dredging
Safeguard.In the case of shielding, hand excavation only affects waters, local, and surrounding still keeps original current
Motion and Sedimentation condition, locally back-silt and tend to restoring to the original state in waters.When having building to screen, to week
To there is appreciable impact and form new water movement and Sedimentation condition in collarette border, hand excavation waters can
Improve the depth of water, but have the area of sediment source will back-silt under wave, trend and littoral flow effect.
The harbor siltation of river and Hekou Area thereof is closely related with its sedimentary loading.Main flow swings and change in bed level develops
Impact even more important.Harbour is more deeply and relatively flat water is easiest to back-silt.Therefore, maintainability is dredged
Dredge the most indispensable.This dredging has Seeding location and stablizes and activity duration regularly feature, also should be conscientious
Determining earth processing mode and suitable mud ground point of throwing, back-silts in minimizing harbour.In order to improve the effect of maintenance dredging
Rate, at a certain distance from hand excavation waters is left in next husky side, digs dell in advance and assembles silt beneficially concentration
Dredging.Various dredgings all must select corresponding dredger and other dredgers according to waters substrate and environmental condition
Tool.
