(c) baffle device for water with suitable dash area is installed on the below, front side of an engineer operation ship;
(d) in the front lower place of described baffle device for water one Apparatus for the mixing of mud is set;
(e) the engineer operation ship that described baffle device for water and Apparatus for the mixing of mud will be housed is transferred to the river course of clear silt construction, makes it Parallel to the flow direction and advances, and dredges out dark narrower water stream channel in advance and makes and stir and pulverize the mud pulp-water and mainly from then on flow out in the passage;
(f) with some high-pressure hydraulic pumps the mud that is stirred and pulverize is taken away with current.
Implement the device that said method adopted, include:
One engineer operation ship and some high-pressure hydraulic pumps are characterized in, comprise that also one is located at baffle device for water and on described engineer operation ship two front sides and is located at Apparatus for the mixing of mud on the described baffle device for water front lower place.
Described baffle device for water comprises that the left and right dash of the detachable adjustment on the left and right side below that is separately positioned on fore-body is pulled piece and is located at each dash and pulls spike on piece and side the place ahead; This spike is provided with a paracone end so that it can insert in the silt of ship front side under thrust.
Adopt method and apparatus of the present invention, the difference that not only can realize flooding is come increased water flow speed, and can be by bed-silt being stirred and fragmentation with waterpower of mechanical force, and is taken away by current; In addition,, thereby therefore can utilize flow energy can reduce power consumption, improve the dredging quality because construction direction is consistent with water (flow) direction.This shows method and apparatus of the present invention owing to realize high flow rate, big flow and the comprehensive function of many power so that a large amount of mud is stirred fragmentation and flows out sluice with current, therefore compared with prior art, its efficient is higher, and cost is low.
Now also specify its purpose and characteristics in conjunction with the accompanying drawings by a most preferred embodiment of the present invention.
