Description

Technical Field

[0001] The invention relates to the technical field of dredging, in particular to a Yellow River dredging and sand discharge platform. Background Art

[0002] The Yellow River contains a lot of sediment, and the river channel will quickly accumulate sediment. In order to restore the normal function of the Yellow River channel, it is necessary to clear the silt and dredge the sediment. In the prior art, a variety of river channel dredging and sediment removal platforms and devices are disclosed, such as the vortex gas disturbance estuary fine-grained sediment dredging device and dredging method proposed in the Chinese invention patent with publication number CN107724449B. The dredging device vortex gas disturbance estuary fine-grained sediment dredging device and dredging method connect the vertical air intake pipeline with the vortex gas disturbance component, and the external air compressor passes high-pressure gas to the vortex gas disturbance component through the air intake pipeline. The high-pressure gas enters each air chamber of the vortex gas disturbance component and then sprays out from the nozzle. The spray direction is directly opposite to the 45° air guide slope, which ejects the gas in an upward direction, driving the water body containing fine-grained sediment to move upward, and disturbing and dredging the fine-grained sediment in the estuary.

[0003] The above-mentioned existing dredging device transmits high-pressure air to the dredging device through an external high-pressure gas system, so that the high-pressure air impacts the silt at the bottom of the river channel, disturbs the silt and then dredges it. However, when the water depth of the river channel is large, the required air pressure is also large, and the requirements for the external high-pressure gas system are high. Moreover, the disturbed and dredged silt directly diffuses into the river water, which is not conducive to discharging the silt from the river channel. Therefore, improvement is needed.
