River dredging dredger

Abstract

The invention provides a channel cleanout mud dredger. The channel cleanout mud dredger moves along with a boat, and is provided with an enclosed mud shoveling box. During working, sludge and muck are gathered on a collecting portion on the back of the box, and are conveyed onto the boat by using a conveyer through a pipeline, thereby fulfilling the aim of dredging a channel without running, dripping and leaking on the premise of not enclosing the channel; moreover, an auxiliary monitoring device can be used for transmitting the real condition of a river bed synchronously. The channel cleanout mud dredger comprises a bracket assembly and a mud dredger assembly, and is characterized in that a bracket in the bracket assembly is erected on the boat, the tail end of the bracket is hinged to a controller, a hydraulic device is arranged between the bracket and the controller, and a main rod in the mud dredger assembly is arranged in the controller.

Description

technical field [0001] The invention relates to a dredger. Background technique [0002] River siltation has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. In order to restore the normal function of the river and promote the rapid and sustainable development of the economy and society, dredging projects for the river are carried out. The river channel will become deeper and wider through treatment, and the river water will become clearer. The production conditions and living environment of the people will be significantly improved, and the goal of "clear water, smooth river, green banks and beautiful scenery" will be achieved. [0003] At present, the removal of river silt generally needs to go through: filling cofferdams to close the river in sections, pumping water, sewage suction pumps to suck up sludge to tank trucks for unloading, manual cleaning of muck (including garbage and ...

AI Technical Summary

Problems solved by technology

The construction process is complicated, and the river course will be interrupted during the period, which will affect the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. It also has the disadvantages of long construction period, large amount of engineering, and high cleaning costs.

[0004] If the long-arm excavator in the pontoon is directly used for excavation, the impact on various functions of the river channel will be basically eliminated, and the cost and time of river channel sediment cleaning will be greatly reduced. Part of the silt will be lost, and the "running, dripping, and leaking" in the process will mix the river water for secondary pollution, and at the same time, the dredging effect will also be significantly reduced. Therefore, it is rarely used, and it is generally implemented only as a last resort.
