Automatic accumulation scavenging system for e.g. tunnel drainage, has collection container connected with drainage conduit or collective pipe, and scavenging wall with high flow speed of water wash out

摘要

The system has an accumulation scavenging unit (1) provided with a sewage flusher or a feed lifer that is installed in a collection container (2) with over flow unit, drain outlet and inlet. The collection container is connected with a drainage conduit or collective pipe (4), where the container and conduit are stowed up to a triggering point of the scavenging unit during the water flow at the container and conduit after triggering the discharging at the container and conduit through the scavenging unit. The scavenging wall with high flow speed of water wash out is deposited in a line.
