Technical Field
The utility model belongs to the technical field of the silt is handled, the occasion that needs regular desilting such as concretely relates to municipal administration river course, lake mud flat and aquaculture base.
Background
River channel siltation increasingly affects the normal performance of various functions such as flood control, waterlogging drainage, irrigation and water supply, navigation, ecological environment and the like, and in order to recover the normal functions of the river channel and promote the rapid and continuous development of the economic society, the river channel needs to be regularly dredged.
At present, several common modes for underwater dredging are grab bucket type dredging, pump suction type dredging, common cutter suction type dredging and the like.
Grab bucket type dredging: the grab bucket is used for grabbing the sludge, the sludge is directly unloaded into the sludge barge and then is conveyed to a sludge storage yard, the construction process is simple, the sensitivity to extremely soft bottom sludge is poor, hard stratum earthwork at the lower part of a riverbed is easily damaged, and the sludge removal rate can only reach about 30%.
Pump suction type dredging: the hydraulic dredging water gun and the mud suction pump are simultaneously arranged in 1 cylindrical cover, the water gun sprays water to stir bottom mud into mud, the mud is sucked out by the mud pump on the other side and then is conveyed to a storage yard on the bank through a pipeline, a large amount of river water can be sucked out by the mode, the subsequent mud treatment workload is increased, and meanwhile, the mud suction port is blocked by rubbish objects in water.
Ordinary cutter-suction type dredging: the device consists of a floating body, a reamer and a suction pipe pump, wherein slurry is formed by cutting and stirring the bottom of a riverbed and mixing muddy water, and is sucked by a centrifugal pump on a ship and pressurized and sent to a storage yard. The method belongs to open excavation, easily causes the diffusion of pollutants in bottom mud, and can cause a more serious silting phenomenon. The clearance rate of the bottom mud is about 60 percent generally. The slurry concentration is low, so that the volume of the slurry is increased, and the occupied area of a sludge storage yard is increased.
Although different process technologies are adopted in the several dredging modes, different dredging occasions can be met, the common problem is that the sludge is purely salvaged and cleaned, the influence on the water environment is not considered, the problem of disposing the sludge with the initial water content of more than 80% is not considered, and the workload of subsequent sludge treatment is still huge.
