METHOD OF HYDRAULIC DREDGER OPERATION Russian patent published in 2017 - IPC E02F3/88 

FIELD: construction.

SUBSTANCE: method of hydraulic dredger operation which comprises development of water storage by hydraulic dredger or purification of water storage, wherein after completion of the development or purification of water storage, the suction pipeline or its part is disconnected, soil pump is started by retaining at least the suction nozzle and immersing its open end into water, increasing the rotation frequency by 25-35%, and the pipeline is being rinsed from the residual ground masses for at least 30 minutes, after which water is supplied to the consumer through its own discharge pipeline or pre-connected water supply pipeline. The suction nozzle can be made in the form of a flexible corrugated hose, the open end of which is equipped with a protective basket or grid and rigidly connected to the body of the hydraulic dredger, immersing it to a depth of 1.4-2.7 m. Drive of the soil pump is performed from the diesel engine.

EFFECT: expansion of the technological capabilities of the hydraulic dredger and exclusion of expenditures for construction and pump station creation.
