AI Technical Summary
In situations where the river channel is deep and the width of both banks is limited, the existing inverted siphon structure cannot meet both the requirements for the depth of the installation gate slot and the scouring depth of the pipeline, resulting in increased construction difficulty and equipment control challenges.
The system employs an inlet well group and an outlet well group set up on both sides of the river channel, connected by an inverted siphon to form a U-shaped structure. The inlet well group and the outlet well group each contain a gate slot well and a water storage chamber, respectively. The flow of sewage is controlled by a gate, which reduces the installation depth of the gate slot and facilitates maintenance.
It achieves a simplified construction method, reduces equipment requirements, lowers construction difficulty, ensures stable system operation, and provides an economical and feasible sewage treatment effect under conditions of deep river channels and limited width on both banks.
