Deep Cement and Sand Rapid Removal System and Method Based on Pneumatic Sand Discharge

Abstract

A deep cement and sand rapid removal system and method based on pneumatic sand removal. The rapid sediment removal system includes a compressed air source, a sand discharge mechanism and a control system. It is characterized in that an air compressor is provided in the compressed air source, and the air compressor is connected to the gas storage tank and then connected to the The pipeline is connected to the sand discharge mechanism; the sand discharge mechanism includes an underwater sand flushing air row and its interface equipment; the control system includes a control computer, and the output signal of the sensor in the underwater sand flushing row and its interface equipment is connected to the The control computer, the output command of the control computer is connected to the compressed air source through the actuator. The equipment and method of the present invention are used for rapid transport of sediment in reservoir rivers, downstream approach channels of water engineering ship locks, and port channels under tidal sluices to reduce and prevent siltation in river port channels and hydraulic discharge structures Matter sediment deposition, especially for fine-grained sediment has a more obvious effect.

Description

technical field [0001] The invention relates to a sand erosion and silting technology, in particular to a sand erosion and silting control system based on pneumatic sand discharge. The invention also relates to the working method of this system. Background technique [0002] At present, dredgers are used for dredging in the mainstream, and the boats drive drag rakes to remove local sediment deposits. However, under normal conditions, there is continuous sand coming from the upper reaches of the reservoir. Among the existing dredging methods, the efficiency is not high, and human cooperation is required, and the capital investment is relatively large; the introduction of pneumatic sand removal methods into deep cement sand dredging has good development prospects. [0003] The rivers in our country have a lot of silt and fine particles, which cause serious siltation of water conservancy projects. After the sediment enters the sea, it forms a vast muddy or silty muddy coast, ...

AI Technical Summary

Problems solved by technology

At the same time, the siltation of reservoirs, silts under tidal sluices, port channels, ship lock approach channels, and water intakes of power stations in China is more serious than similar foreign projects, hindering the benefits of water conservancy, water transportation, and hydropower projects.
