Embodiment 1
[0048] Such as Figure 1-9Among them, an intelligent diversion well that prevents the backflow of sewage interception main pipes, including a water inlet chamber 1, a sewage interception chamber 2 and a water outlet chamber 3 arranged in a foundation enclosure 6, and the sewage interception chamber 2 and water outlet chamber 3 are located in the water inlet chamber 1- On the side, a drainage pump 4 is provided between the water inlet chamber 1 and the sewage intercepting chamber 2, and an anti-backflow device 5 is provided between the water inlet chamber 1 and the water outlet chamber 3. The drainage pump 4 and the anti-backflow device 5 are used to control the sewage interception Chamber 2 and the communication between the water outlet chamber 3 and the water inlet chamber 1. Drainage pump 4 adopts QJB-W pump, which has controllable overall operation and high precision. The anti-backflow device 5 can adopt bottom opening weir gate, hydraulic rotary weir gate, hydraulic non-re...
Embodiment 2
[0064] The method of using the anti-sewage interception main pipe for backfilling the intelligent diversion well includes the following steps:
[0065] S1. In the initial state, the drainage pump 4 is closed, the anti-backflow device 5 is closed, and the water inlet chamber 1 and the sewage interception chamber 2 are kept connected;
[0066] S2. Real-time monitoring of the real-time water level hj of the water inlet chamber, the real-time water level hw of the sewage interception chamber and the real-time water level hc of the water outlet chamber, and record the data;
[0067] S3. When it is sunny, the drainage pump 4 is corresponding or closed according to the water level h2 (set maximum value), hw and hj of the water inlet chamber;
[0068] S31. If hw≤h2, keep the initial state;
[0069] S32. If hw≥h2, turn on the drain pump 4 until hj drops to the water level h1 (minimum value set) in the water inlet chamber, and turn off the drain pump 4;
[0070] S33. When a rain warni...
