Abstract

The hydraulic gate valve operates automatic completely on force balance principle of back and font gate. For the works of dewatering tides and waterlogging, preventing saltwater from entering the field, automatic valve gate is a superior technical solution. However, the feature of this gate when to set automatic mode, the gate cannot regulate and control the upstream water level, the water will automatically drain until it balances with the downstream water level. Studying the structure of combination with automatic valve gates for the works in
exploiting the technical features of automatic gate in terms of drainage but still controlling the upstream water level, this is very necessary and to bring high efficiencyto the operation management. The Tra Bong Dam (Quang Ngai) is desiged to combine a free overflow structure with an automatic gate to prevent tides, keep fresh water and drain water, keep the upstream water level stably. There is no need for forced operation of the gate to drain water in time at low tide, bringing high economic and operational efficiency.
