Problems solved by technology

[0003] Inverted siphon bottom pipes are prone to sedimentation and silting during long-term operation, which seriously affects the water passing capacity, and once silting occurs, dredging is difficult, and hundreds of thousands or even higher dredging costs are often incurred
[0004] At present, the method of increasing the slope of the inverted siphon bottom pipe is used to solve the deposition phenomenon of the inverted siphon bottom pipe and reduce the dredging work, but the inventor found that this method needs to increase the buried depth of the downstream inverted siphon well, which increases the construction period and complicates the construction degree and construction cost

Embodiment 2

[0046] This embodiment discloses the desilting method of the pouring system described in Example 1: the sewage in the upstream sewage pipe enters the upstream pouring well, and the larger impurities in the sewage are intercepted under the action of the grid plate and remain in the desilting The sewage in the slag space and the sedimentation space enters the inverted siphon after the impurities are precipitated. At this time, the sewage in the inverted siphon has less impurities. The sewage in the inverted siphon enters the downstream inverted siphon well and then flows out through the downstream sewage pipe. After a period of use Finally, there will still be impurities remaining in the inverted siphon. At this time, the staff opens the first inspection well and the second inspection well corresponding to the second chamber and the third chamber, and uses the control system to control the first motor and the second motor to drive The rotation of the first turntable and the secon...

Abstract

The invention relates to an inverted siphon system and a desilting method. The inverted siphon system comprises an upstream inverted siphon well communicated with an upstream sewage pipe, a downstreaminverted siphon well communicated with a downstream sewage pipe, an inverted siphon pipe which is horizontally arranged, and the two ends of the inverted siphon pipe are communicated with the upstream inverted siphon well and the downstream inverted siphon well; the inverted siphon system further comprises a desilting floating ball, the desilting floating ball is connected with a traction piece,and the traction piece can drive the desilting floating ball to reciprocate in the inverted siphon pipe in the axis direction of the inverted siphon pipe; and the inverted siphon system is simple in structure, low in construction cost and short in construction period.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to an inverted rainbow system and a dredging method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Inverted siphon bottom pipes are prone to sedimentation and silting during long-term operation, which seriously affects the water passing capacity, and once silting occurs, dredging is difficult, and often hundreds of thousands or even higher dredging costs will be incurred. [0004] At present, the method of increasing the slope of the inverted siphon bottom pipe is used to solve the deposition phenomenon of the inverted siphon bottom pipe and reduce the dredging work, but the inventor found that this method needs to increase the buried depth of the downstream inverted siphon well, which increases the construction period and complicates the construc...
