The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

According to the novel intercepting well provided by the present disclosure, as shown in fig. 1 and 2, the intercepting well comprises a combined system pipeline 1, a ladder stand 3, a trash rack 4, an overflow pipe 5, a sewage pipeline 6, an overflow weir 8, an intercepting well box culvert 9, a well lid 11 and an intelligent control system; the combined system pipeline 1 is connected with the intercepting well box culvert 9; the overflow weir 8 is positioned inside the box culvert 9 of the intercepting well, and the trash rack 4 is respectively arranged above the overflow weir 8 and at the pipeline inlet of the sewage discharge pipeline 6; the intelligent control system comprises an intelligent control cabinet 2, a sewage gate 7, an online monitoring instrument and a liquid level meter sensor; the intelligent control cabinet 2 is positioned in a gate control box on the flat ground outside the box culvert 9 of the intercepting well; the sewage gate 7, the online monitoring instrument and the liquid level meter sensor are positioned in a box culvert 9 of the intercepting well; the blowdown gate 7 is arranged at the joint of the blowdown pipeline 6 and the intercepting well box culvert 9.

The intelligent control cabinet 2 is connected with a sewage gate 7, an online monitoring instrument and a liquid level meter sensor which are arranged in a box culvert 9 of the intercepting well through communication cables; the signal input end of the intelligent control cabinet 2 is connected with an online monitoring instrument and a liquid level meter sensor, and the signal output end controls a sewage gate 7. Through connecting intelligent control cabinet 2 in the terminal computer, realize long-range wisdom management.

The on-line monitoring instrument and the liquid level meter sensor are installed in the middle of the intercepting well box culvert 9 and close to the position of the blowdown gate 7.

Cutoff well box culvert 9 is divided into front side box culvert and rear side box culvert by overflow weir 8, the cross-sectional area ratio of front side box culvert and rear side box culvert is 2: 1, because the cross-sectional area of the front box culvert is larger than that of the rear box culvert, the retention time of sewage can be prolonged, and sludge can be intercepted at the front box culvert as much as possible.

The blowdown gate 7 is a lower open type hydraulic blowdown gate, and the blowdown gate 7 can be completely opened or closed under the control of the intelligent control cabinet 2, so that the problem of water flow backflow can be effectively solved; the on-line monitoring instrument is a dissolved oxygen on-line monitoring instrument and can monitor the water quality in the box culvert 9 of the intercepting well in real time.
