Sediment removal apparatus for float in river channel sludge and measuring method of float in river channel sludge

Abstract

The invention relates to a sediment removal apparatus for float in river channel sludge. The sediment removal apparatus comprises a hull, sludge collectors, a sludge pump, a sedimentation tank and a sampling barrel. The sludge collectors are connected to the two sides of the hull. Each sludge collector includes a sludge collection pipe, a sludge collection port and a sludge shoveling collector; each sludge collection pipe is provided with the corresponding sludge collection port which is fitted with the corresponding sludge shoveling collector; each sludge collection port collects sludge of the float into the sludge collection pipe through the sludge shoveling collector; the sludge collectors are connected with the sludge pump inside the hull through corrugated pipes; a sludge outlet of the sludge pump is connected to the sedimentation tank through a pipeline; one side of the hull is provided with a lifting terrace; the sampling barrel is fixedly connected to the lifting terrace. The sediment removal apparatus enables sludge of the float in the river channel sludge to be collected and sedimented; the float is removed from a river channel; the thickness of the float before and aftermeasuring can be measured so as to confirm cleanliness degree.

Description

technical field [0001] The invention relates to the technical field of river channel management, in particular to a sedimentation removal device and a measuring method for floating layers in river channel sludge. Background technique [0002] Siltation in small and medium-sized rivers is relatively common in my country, and the original ability of rivers to regulate and store floods and prevent and mitigate disasters has been weakened. In recent years, the state has strengthened the management of small and medium-sized rivers and rural rivers, and dredging projects have been widely implemented as the main measure. At present, river dredging has expanded from the traditional water conservancy project goal of improving river flood control, drainage and irrigation capabilities to ecological water conservancy goals. That is to say, the goals of many river dredging projects include reducing river internal source pollution. The engineering purpose of providing guarantee for the impr...

AI Technical Summary

Problems solved by technology

[0004] The prior art solutions above have the following defects: 1. It is impossible to clean up the sludge in the floating layer on the surface of the river. The salvage mechanism can only salvage the sludge at the bottom of the river, but it will break up the sludge in the floating layer, which is even more difficult Collection and processing

[0005] 2. It is impossible to measure the sludge thickness of the floating layer of river sludge, and it is impossible to compare the sludge before and after cleaning, so it is impossible to confirm the effect of sludge removal
