Abstract:
With the development of the new national key water conservancy projects such as the of South-to-North Water Diversion Project, East- to- South Water Ddiversion Pproject, and Water Diversion Project from Yellow River to Qingdao, construction project, when the project is completed, the main channels undertake not only the water diversion duty but also the drainage of flood discharge task; therefore sediment deposition occurs in these channels. in addition to water diversion outside part of trunk channels to release flood waters and task, sediment deposition can hardly be avoided. Based on the dredging of water conveyance channel with concrete lining in the Eastern Route of South-to-North Water Diversion Project, an automatic dredging machine was developed to complete the dredging task through the dredge suction system and transport system. The machine can receive the instructions of ashore personnel or perform independent judgment to determine the distribution of dredge, and therefore decide its walking methods, turn and avoid obstacles, and control its position in water. The new channel dredging equipment is a small dredging equipment, and can be applied to the environmental protection dredging of channels, lakes, and waterways, dredging, environmental protection dredging reservoir sand basin dredging, and river management etc.. Meanwhile, It is a kind of the diving dredging machine automatic suction system, slurry transport system to complete the dredging task. And it can receive the instruction or independent judgment on underwater silt distribution, and to decide the way of walking in the water, to achieve turning, avoiding obstacles, control their water in the range. At the same time, the dredging equipment would not cause the secondarycan not cause two times environmental pollution and underwater cutout during the, and do not cause dredging process of underwater cutout. The new equipment Also has the advantages of high efficiency, energy saving, convenient easy operation, lowsmall labor intensity, broad suitable workingapplication range, and low cost .etc.
