Description

Anti-blockage type environment-friendly dredging vehicle for river channel and dredging method

Technical Field

The invention relates to the technical field of river channel dredging, in particular to an anti-blocking type environment-friendly dredging vehicle for a river channel and a dredging method.

Background

Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harmful substances and benefiting. Also known as water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims.

River channel desilting generally refers to the treatment of river channels, and belongs to hydraulic engineering. The silt deposited at the river bottom is blown and stirred into turbid water through mechanical equipment and flows away along with river water, so that the dredging function is achieved.

River channel siltation increasingly affects the normal performance of various functions such as flood control, waterlogging drainage, irrigation, water supply, navigation and the like, and river channel dredging engineering is carried out for recovering the normal functions of the river channel and promoting the rapid and continuous development of the economy and society. The river course becomes deep and wide through treatment, the river water becomes clear, the production conditions and the living environment of the masses are obviously improved, and the aims of 'clear water, smooth river, green bank and beautiful landscape' are achieved.

Sludge is soft soil with natural water content greater than the fluidity limit and porosity greater than 1.5. Is a modern sediment formed under the condition that microorganisms participate in the slow water flow in the gulf, lake or river.

The sludge is rich in organic matters, is usually gray black, and has low mechanical strength and strong compressibility. Its shock resistance is poor. Under the action of strong earthquake, the foundation of the building is easy to sink.

Due to large flow and long accumulation time, the river sludge is easy to generate regional enrichment and present the conditions of soil layer accumulation and caking.

The existing river channel dredging equipment has some problems, in order to ensure the action area, the existing dredging head mostly adopts a flaring design, but if a negative pressure type adsorption design is adopted, the adsorption force of the flaring part is smaller; the existing dredging head has poor sludge adsorption effect on the bottom agglomerates of the river channel due to the large weight and volume of the sludge blocks; simultaneously the silt piece still easily causes the circumstances that the desilting head produced the jam, needs to shut down the processing to the desilting head, causes desilting efficiency to receive the influence, needs to improve.

Therefore, the inventor designs the anti-blocking type environment-friendly dredging vehicle for the river channel and the dredging method, so that the sludge blocks at the bottom of the river channel are broken and crushed and then sucked to realize dredging, and the problems are solved.
