Shoal river bed dredging device and method
The invention discloses a shoal river bed dredging device and method. The dredging device comprises a floating carrier, wherein a supporting device, a stopping device and a sand sucking pump are arranged on floating carrier; the sand sucking pump in the non-working position or the working position can be connected with the floating carrier together in a switched manner; the sand sucking pump is supported by the supporting device when in the non-working position, and is propped against the stopping device when in the working position; the sand sucking end of the sand sucking pump is in contact with the river bed mud surface; a water outlet of the sand sucking pump is connected with a sludge water conveying pipeline extending to the riverside sludge stacking part. According to the device, muddy water mixed up with sludge is absorbed through the sand sucking pump, sludge is conveyed to shoreside through the conveying pipeline, the river way can be effectively cleaned, secondary siltation can be prevented, and the environment cannot be polluted, but can be protected. The device is relatively light in weight, no large-scale mechanical equipment needs to be adopted, and the construction cost is relatively low.
