A sedimentation removal device and measurement method for floating layer in river sludge

Abstract

The invention relates to a sedimentation removal device for a floating layer in river sludge, which includes a hull, a sludge collection device, a mud pump, a sedimentation tank and a sampling bucket. Both sides of the hull are connected with collection devices, and the collection device includes a sludge collection device. Pipeline, sludge collection port and sludge shovel collector, the sludge collection pipe is provided with a sludge collection port, and a sludge shovel collector is installed at the sludge collection port, and the sludge collection port passes through the sludge shovel collector Collect the sludge in the floating layer into the sludge collection pipeline, the collection device is connected to the mud pump located inside the hull through the bellows, the mud outlet of the mud pump is connected to the sedimentation tank through the pipeline, and one side of the hull is set There is a lifting platform, which is fixedly connected with a sampling bucket, which can collect and settle the sludge in the floating layer in the river sludge, clean the floating layer from the river, and measure the thickness of the floating layer before and after cleaning, so as to This is to compare and confirm the cleaning effect.

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
