Comparison of Ditch Dredging Methods in Flood Control Treatment
In order to explore the economical,applicable and feasible technology mode of urban river dredging,the urban section of Handan City in Fuyang River is taken as an example.On the basis of summarizing the current situation of river siltation,combined with the current engineering practice experience,comparative analysis of the two modes of hydraulic dredging and mechanical dredging is carried out.a preliminary flood control and treatment plan for Fuyang River is proposed,which includes hydraulic dredging,pipeline transportation,and natural air drying technology.Then,the performance and applicability of the underwater dredging machines,including the rake suction dredger,twisted suction dredger,chain bucket dredger,grab bucket dredger and so on,are compared;The final decision is to adopt a dredging process that combines a small ecological and environmentally friendly dredging ship with a dedicated dredging platform,and to analyze and verify the dredging treatment effect and superiority of this process.The results show that the small ecological environmental protection dredging ship dredging technology is an emerging dredging technology developed on the basis of overcoming the disadvantages of traditional dredging technology.It has high dredging efficiency and can effectively avoid secondary pollution to the environment.The quickly solidified sediment and tail water can be used as resources,and has excellent economic and ecological benefits.
