Problems solved by technology
This technology has the advantages of simple equipment, convenient transportation, and low construction cost. However, due to the use of hand-held water guns to spray and sweep the palace, the physical exertion is extremely high, and then the mud is sucked by mud pumps and transported by pipelines, and the mud is transported to the pile on the shore. The construction environment of this method is relatively harsh, and at the same time, it has great restrictions on the physical strength of the operators.

Embodiment Construction
[0022] Such as figure 1 , figure 2 As shown in the figure, the hydraulic medium and small scour dredging and dredging device of the falling water scouring type river bottom mud is applied in small and medium river courses. The ram is placed in the target channel for desilting through the interception project. The width of the ram is consistent with the river bed, and the height is equal to the depth of the channel, which meets the requirements for water cut-off and interception. From top to bottom, the gate includes the No. 1 rotating plate 1, the No. 2 rotating plate 2, the No. 3 fixing plate 3, the No. 4 fixing plate 4 and the No. 5 rotating plate 5. The lower edge of the No. 1 rotating plate 1 passes through a No. hinge 6 is hingedly installed, the lower edge of No. 2 rotary plate 2 is hingedly installed through No. 2 hinge 7, No. 3 fixed plate 3 and No. 4 fixed plate 4 are fixed and installed through fixed bolt 9, and the upper edge of No. 5 rotary plate 5 is hinged thro...

The invention belongs to the technical field of river regulation, and particularly relates to a dredging device for hydraulic drop scour type river sediment waterpower medium and small scouring and excavating and a dredging method thereof. The dredging device for hydraulic drop scour type river sediment waterpower medium and small scouring and excavating comprises a mud bucket and a flashboard. The flashboard is located on the upstream of the mud bucket, and the flashboard comprises a first rotary plate, a second rotary plate, a third fixed plate, a fourth fixed plate and a fifth rotary platefrom top to bottom in sequence. The lower edge of the first rotary plate is mounted in a hinge joint mode through a first hinge, the lower edge of the second rotary plate is mounted in a hinge joint mode through a second hinge, the third fixed plate and the fourth fixed plate are fixedly mounted through fixed bolts, and the upper edge of the fifth rotary plate is mounted in a hinge joint mode through a third hinge. Through combined effects of controlling the fifth rotary plate at the bottom and the first rotary plate at a weir opening, the turning starting angle of the second rotary plate andwaterpower hydraulic drop scouring, river sediment drain dredging with low loss and high efficiency is realized, a traditional method of high-pressure water gun souring sediment by adopting a waterpower scouring and excavating machine set is changed, and manpower and power consumption are greatly saved.
Description
technical field [0001] The invention belongs to the technical field of river course management, and in particular relates to a dredging device and a dredging method for small and medium-sized hydraulic dredging and dredging of river channel bottom mud by falling water. Background technique [0002] In my country, urban river water pollution has become a serious urban disease, so water purification and restoration has become a hot spot of public concern. Therefore, solving water pollution and restoring water ecological and social functions is one of the key tasks to be solved in the process of sustainable development. At present, the most important and convenient treatment technology for urban water body is river dredging and hydraulic scour dredging in dredging technology. This technology has the advantages of intuitive construction status and easy quality assurance. Suspended solids, chlorophyll a, and water transparency are significantly reduced, which is an effective mea...
