Embodiment 1

[0029] Embodiment 1: a kind of river channel dredging device, as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, including the hull 1 and the water suction pipe 2, the top of one side of the hull 1 is fixedly provided with a connecting piece 3, and the top of the water suction pipe 2 is connected with a connecting pipe 4, and the connecting pipe 4 and the connecting piece 3 are connected by a limiting mechanism 5, and the The top of the tube 4 is provided with a motor 6, and the bottom of the motor 6 is equidistantly fixed with several connecting rods 7, and the bottom of the connecting rod 7 is fixedly connected with the top of the connecting pipe 4, and the output shaft of the motor 6 is fixedly provided with a stirring rod. Head 8, one side of hull 1 top is fixedly provided with fixed seat 9, and fixed seat 9 is close to connector 3, and fixed seat 9 is connected with semicircle salvage part 11 by movable mechanism 10, and se...

Embodiment 2

[0036] Embodiment 2, the above-mentioned river channel dredging device is installed on the environmental protection cutter suction dredging ship to carry out the construction method of urban ecological river channel underwater dredging, as attached Figure 8 , with Figure 9 and attached Figure 10 As shown, the construction method includes the following steps:

[0037] (1) Floating pipe laying

[0038] Floating pipes for actual needs are arranged behind the environmental protection cutter suction dredging ship, and 6m long steel pipes are used to penetrate buoy form floating pipes, and 1.5m long rubber pipes (rubber sleeves) are used to connect the steel pipes flexibly, so that the dredger mud pump The body output pipe and the submerged pipe have a good room for movement, and the laying line of the floating pipe is approximately streamlined and curved. Because the floating pipe has to bear the impact of water flow, wind and waves, and the impact of blow-fill construction, ...

Abstract

The invention discloses a river channel dredging device and a construction method using the device. The device comprises a ship body and a water suction pipe, a connecting piece is fixedly arranged atthe top of one side of the ship body, the top end of the water suction pipe communicates with a connecting pipe, and the connecting pipe and the connecting piece are connected through a limiting mechanism. According to the device, the water suction pipe, an external underwater pipeline, a water pipeline and a land pipeline are matched, cut water grass, duckweed and the like are discharged to theoutside, the water is filtered and then conveyed to the original position, and the collection efficiency of the cut water grass and the duckweed is improved through a fishing net. Through the device,dredging is achieved, the water grass, the duckweed and the like can also be removed, the utilization rate of resources is improved, and practicability is enhanced.

Description

technical field [0001] The invention relates to the design technical field of environmental protection facilities and equipment and cleaning technology, and specifically discloses an underwater environmental protection cutter suction dredging device for urban ecological rivers and a construction method thereof. Background technique [0002] In river dredging and dredging projects, the ship is usually used as the power, and the motor drives the reamer to stir the sludge. Through the mud pump and the suction pipe, the mud-water mixture is sucked up by the underwater pipeline, the water pipeline and the land pipeline and discharged into the sludge collection tank. Not only can construction be carried out in rainy days, but there is no need to cut off the flow. At present, the device used for river dredging has a single function and is only used for dredging the river, which has low practicability, and the river dredging device is usually idle after dredging the river, resulting...
