- Abstract
In view of the special requirements that the open channel of South-to-North Water Diversion Project should not stop water and desilt and cannot affect the quality of water conveyance in the process of desilting, a new desilting system that can work stably in dynamic wa⁃ ter environment is proposed. In this paper, through the force analysis, calculation and model test of the integral dredging system on water and underwater, the hydraulic characteristics of the dredging system are analyzed, and its stability in the dynamic water environment is verified. The results show that when 200 mm× 200 mm× 8 mm× 12 mm H-beam is selected as the connection truss of the underwater system connect⁃ ing each dredging bin unit, the self-weight of the whole system(67 557.8 N)is more than the buoyancy of the whole system(50 558.4 N). The installation of process vacuum suckers on both sides of the dredging system can improve the anti-floating stability safety factor of the dredging system from 1.13 to 1.80. The force on the dredging system under the action of water flow meets the anti-floating stability require⁃ ments of the overall dredging warehouse in the hydrodynamic environment. The research results serve as a reference for the anti-floating stability study of water retaining structures such as moving water dredging, river crossing and canals.
