Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dredging equipment, in particular to a river sludge dredging device and method. BACKGROUND

[0002] River dredging generally refers to river regulation and belongs to water conservancy engineering. Through mechanical equipment, the silt deposited at the river bottom is blown and stirred into turbid water, which flows away with the river water, thereby playing a dredging role. However, after dredging in this way, the sludge will settle in the slow flow area, causing the downstream river to be blocked and increasing the pressure of downstream dredging work. The existing dredging methods generally use mechanical equipment to suck the sludge and then spray it to the two sides of the river bank or use transport equipment to transport it to the treatment plant for treatment.

[0003] The existing dredging device is generally arranged on a ship body, and the ship-type dredging equipment is large in size and not flexible enough to move, and cannot adapt to the dredging work of small rivers. At the same time, the dredging of small rivers is generally carried out during the dry season or low water level. In this case, the traditional ship-type dredging equipment cannot normally travel and dredge, so the current dredging work of small rivers generally uses excavators or sludge pumps for dredging. However, the excavator is easy to get stuck in the sludge, and cannot work at low water level. The method of directly pumping sludge using a pump requires a large amount of work for workers, and pipes need to be arranged and the position of the pump needs to be constantly moved for dredging work at different positions.
