Intercepting well with backward flow preventing and safe flood drainage functions

Abstract

The invention provides an intercepting well with backward flow preventing and safe flood drainage functions. The intercepting well is arranged at the tail end of a drainage opening entering a river channel system; and the intercepting well comprises a rotary weir gate, a stop log gate, an electric gate, ultrasonic liquid level meters, a remote terminal control system, a hydraulic station and a power distribution cabinet. The rotary weir gate serves as a backward flow preventing facility and is arranged at the overflow end of the intercepting well; the stop log gate is arranged at the end close to the river and installed between the rotary weir gate and the river channel; the electric gate is installed at the position of an intercepting pipe opening of a sewage bin of the intercepting well; and the ultrasonic liquid level meters are arranged in the sewage bin and an overflow bin. The intercepting well can be applied to initial rainwater intercepting, regulating and storing of a drainage system, the intelligent degree is high, the safety coefficient is high, and the flood drainage function is more complete and comprehensive. The intercepting well has the advantages that the depth of a foundation pit is small, the manufacturing cost and the fault rate are low, the water stop effect is good, and equipment replacement is convenient; and automatic opening or pressure maintaining can be achieved during power failure, the system running state can be accurately regulated and controlled, the waterlogging dangerous case under the sudden work condition is prevented, and the intercepting well is suitable for direct drainage opening sewage intercepting in black and odorous water body treatment.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to an interception well which is suitable for initial rainwater interception and storage in a drainage system, and has the functions of preventing backflow and safely draining waterlogging. Background technique [0002] Urban black and smelly water is a water environment problem that people strongly report, which not only damages the urban living environment, but also seriously affects the image of the city. The "Water Pollution Prevention and Control Action Plan" ("Water Ten Measures") promulgated and implemented by the State Council in 2015 clearly stated the goal: before the end of 2017, cities at the prefecture level and above will have no large-scale floating objects on the river surface, no garbage on the river bank, and no illegal sewage outlets. The built-up areas of municipalities directly under the Central Government, provincial capitals, and cities under separate stat...

Problems solved by technology

The current drainage systems in different regions are restricted by local financial and historical factors, and there are different types of drainage systems. Most of the old urban areas are still combined systems, which are difficult and costly to divert; the new urban areas are divided systems. However, there is a more serious phenomenon of splitting and mixing

However, traditional fixed weir interception wells, jumping interception wells, buoy valve interception wells, etc. have a low safety factor for drainage, inaccurate sewage interception, difficult operation and maintenance, and fail to achieve the expected results; the bottom-opening weir gate is used to prevent backflow The interception well of the facility has a deep foundation pit and a high failure rate; the wall-attached electric gate is used as the interception well of the anti-backflow facility, and the two-way water sealing effect is poor, etc.
