METHOD FOR CONSTRUCTION OF SAND BEACH AND DEVICE FOR ITS REALISATION

摘要

FIELD: construction.;SUBSTANCE: subsurface part of the beach is washed from the surface of a water reservoir onto a protective screen laid onto the bottom of the beach subsurface part. Then above-water coastal part of beach is filled. Sand hydraulic mixture is prepared in sump installed in technological trench joined to water reservoir and filled with water. Movement of floating pulp line on water surface of beach is carried out from coast by means of guide ropes. Technological trench is arranged as longitudinal through or dead-ended, or as transverse and dead-ended. Sump is arranged as movable or stationary. Floating pulp line is moved on water surface perpendicularly to coastal line or along semicircle. Device comprises hydraulic transport installation, distribution pulp line equipped with holes, protective screen arranged of tissue materials and sump equipped along perimetre with a safety net, and with a sieve on top. Pulp line is arranged as floating, has a coastal connection and is equipped with guide ropes. Protective screen is equipped with pioneer cantledges.;EFFECT: invention makes it possible to reduce costs and time of beach construction, and to increase their service lives.;12 cl, 2 dwg
