Description

Environment-friendly system and method for clearing and transporting bottom mud of closed water area Technical Field The invention relates to the technical field of hydraulic engineering, in particular to an environment-friendly system and method for cleaning bottom mud of a closed water area. Background In China, a plurality of closed water areas such as reservoirs and lakes exist, and along with the rapid development of urban construction and the improvement of environmental protection requirements, more and more closed water areas face the requirement of environmental protection and clearance of bottom mud. At present, the conventional bottom mud environmental protection and cleaning of the closed water area adopts a cutter suction dredger to dredge, and then is conveyed to a mud discharge field within a certain distance through a mud conveying pipeline, and the water area with low environmental protection requirements and smaller dredging amount can also be dredged by adopting a grab dredger, and then is conveyed to the shore of the closed water area through a dredger to be temporarily carried by a wharf to be carried by the shore, and then is transferred to a dump truck to be transported by the land. However, some closed waters have high environmental protection requirements and larger dredging capacity, and because the condition of arranging a sludge discharge field is not arranged near the limit of the surrounding environment, the sludge cannot be conveyed in a long distance through a sludge conveying pipeline, and the river channels which do not meet a large number of navigation requirements in the closed waters are communicated with the outside, and the sludge cannot be conveyed in and out of the closed waters for a long time through a sludge barge, the river channels which can navigate are often arranged near the closed waters, and the sludge is directly conveyed to a barge in a nearby channel by adopting a conventional dredger for the closed waters in the prior art, but because the concentration of the sludge conveyed by the conventional dredger is low, the water content of the conveyed sludge is very high, and the sludge barge needs to transport a large amount of the sludge outwards, so that the water loss of the closed waters is large, and the cost of the sludge outwards transportation is very high. Therefore, a new system and method for environmental protection and cleaning of the bottom mud of the closed water area are needed, and the problem of environmental protection and cleaning of the bottom mud of some closed water areas at present is solved. Disclosure of Invention Aiming at the defects in the prior art, the application provides an environment-friendly system and method for clearing and transporting the bottom mud of a closed water area, which are used for solving the technical problems of high construction difficulty, high construction cost and high water loss of the environment-friendly clearing and transporting of the bottom mud of some closed water areas in the prior art. In order to achieve the above purpose, the present invention provides the following technical solutions: The utility model provides a closed waters bottom mud environmental protection clear system, closed waters is provided with the sluice that the ship was passed in and out to the slipway or can short-term temporary opening, there is navigation river course close to closed waters, its characterized in that, closed waters bottom mud environmental protection clear system includes pneumatic pump suction dredger, first mud barge, work platform and second mud barge, pneumatic pump suction dredger and first mud barge all are located in the closed waters, the second mud barge is located in the navigation river course, work platform set up in the bank of closed waters, be provided with the suction pump on the work platform, the suction pump communicates with each other with the sediment device and is connected, first mud barge is used for receiving the bottom mud of pneumatic pump suction dredger suction, the suction pump can with bottom mud on the first mud barge is passed through the sediment device discharges to the second mud barge, the second mud pump is used for transporting bottom mud to the mud discharge yard along navigation river course. In one embodiment, the system further comprises a temporary ship-entering device arranged on the shore of the closed water area. In one embodiment, the temporary ship access device is a slipway or a sluice. In one embodiment, the number of first and/or second refutes is a plurality. In one embodiment, the dredge pump is a pneumatic diaphragm pump. In one embodiment, the mud conveying apparatus is a closed or semi-closed device. In one embodiment, the mud conveying device is a high pressure pipeline, a screw conveyor or a belt conveyor. In one embodiment, a mud collector is arranged between the mud suction pump and the mud conveying device for collecting bottom mud overflowed fr
