Intake Water Screening

Stop Log Gates

When intake channels or intake equipment need repairs and when absolute sealing out of water is not necessary, the stop log gate is used as a shut off device.

Depending on the handling facility and headroom available, the stop log gate can be of one or several segments. To ensure effective sealing, replaceable rubber profile sealing is provided on all sides. The gates are designed considering maximum water head. The skin plate is adequately reinforced with stiffeners.

Prior to raising the gate, balancing of water level across the gate is done by means of pressure equalizing values integral with the stop log gate. The valves connected to the lifting lugs are operated with the help of a lifting beam. For ease of handling during lifting and lowering of gates, an automatic engagement/disengagement type lifting beam has been provided.
