Main Types

To date, with the active development of marine and river construction, hydraulic works are becoming more popular and necessary. The construction of new ports, construction of jetties, bays and harbors, new yacht club with white sailing boats - all of these works belong to the hydraulic line. And we can not do without the dredgers. The dredger - an irreplaceable technique in the organization of shore protection and dredging lake. No dredging will not do well in alluvium and the beach, clean pond or river. Everywhere need help dredging equipment.

Dredgers by type of work performed can be divided into Cherpakov, suction, and others. Mnogocherpakovye dredgers do the work in heavy soils, rising from the water clay, and other complex layers of soil. Cherpakov dredge consists of a frame on which the so-called fixed Cherpakov chain - many buckets, similar to the bucket, which are connected in a continuous chain. This design allows for dredging on solid ground, raise the untouched soil layers. In general, Cherpakov dredgers used for capital dredging. Suction dredges are designed to work on lighter soils - silt, sand with shell and others.

Suction dredgers at the same time are more productive the volume of dredged material, because transport to the soil in this type of dredger is water. In suction dredger design of process equipment like a vacuum cleaner. Drum pump consists of the cochlea and impeller. On the suction side of the working line suction dredger has a sample receiver, similar to customer pylezabornik household vacuum cleaner that loosening the soil beneath me, it raises the water flow by pipeline to the pump, which in turn transports groundwater water mixture to the destination. Suction dredgers are used not only in dredging and reclamation for beaches and the creation of the territories.
