Description

Self-propelled multi-functional sand pumping platform

technical field

The utility model belongs to the technical field of sand mining equipment, and mainly relates to a self-propelled multifunctional sand pumping platform.

Background technique

After the completion and operation of the reservoir hub project, it has played an important role in the development of the local industrial and agricultural economy and flood control safety. Most of the reservoirs, especially the reservoirs of sandy rivers, have high sediment concentration in the flood season, and the sediment deposition in the reservoirs will be more serious, which greatly shortens the service life of the reservoirs, leads to a reduction in water storage, and seriously affects the economic development of industry and agriculture in the basin area. .

Many reservoir projects do not consider sand discharge facilities in their planning and design. In order to discharge the reservoir sediment out of the reservoir, they have to use the reservoir diversion tunnel to discharge sand. However, the elevation of the opening and closing platform of the diversion tunnel inlet gate is generally low, and the reservoir water level must be lowered. It takes a lot of gates to open. Sometimes the reservoir is emptied by mechanical hauling and mechanically assisted hydraulic dredging to remove the sediment in front of the dam. However, the cost of cleaning the sediment per cubic meter is very high and consumes a lot of precious water resources.

Sand pumping platforms are commonly used sand mining or dredging equipment in rivers and lakes, but the existing sand pumping platforms have fewer functions, especially not suitable for sand mining or dredging operations in reservoir areas and lake waters with shallow sediment layers. .
