DRAINAGE PIPES WATER RECEIVING CAPACITY ESTIMATION ON APPLICATION OF MODERN PROTECTIVE FILTERING MATERIALS

Abstract

Theoretical estimation of distances between drains, the research results on pilot-porduction field and in laboratory conditions of drainage pipes water receiving capacity with different geotextiles safety filtering materials are given. Method of water receiving capacity idetification is tested in field conditions. It is discoverd that water receiving capacity depends on hydrogeological conditions of drainage laying, working hydraulic drop over drain and it increases with hydraulic drop's rise. Drainage pipes with various safety filtering materials over a year in use were tested. Their water receiving capacity doesn't differ considerably from one of new pipes so safety filtering materials are almost not muded. It is recommended to detect water receiving capacity of drains while testing drainage fuctionality for unsatisfactory water regime on land reclamation facility.
