SYSTEM differential regulation of groundwater level

摘要

FIELD: agriculture.;SUBSTANCE: system is located on reclaimable land divided into fields with drainage-mist collector-drainage network, which has a butterfly valve. The system is equipped with self-regulating mechanism of the subsoil water level, installed at the collector outlet. Self-regulating mechanism is placed in a chamber which is connected through a hydraulic channel with a representative borehole. Self-regulating mechanism consists of a level control with a corrugated insert and overflow edge, wire-block system with a device to configure the system to a given mark of regulation of subsoil water level, and the float-counterweight. Self-regulating mechanism is connected to the water tunnel and the borehole on the principle of communicating vessels, and the level control through the corrugated insert - with a collector-drainage network to control the butterfly valve. The diametre of the level control is equal to the drain diametre.;EFFECT: use of the invention will enable to automate the process of regulating the subsoil water level.;2 dwg
