Novel confluence channel intercepting well
The invention provides a novel confluence channel intercepting well, which comprises a river embankment, wherein a flow-limiting valve well is arranged at the upper end of the river embankment; the flow-limiting valve well is connected to the river embankment by virtue of a pipeline; a spring weir is arranged inside the river embankment; a sand trap is arranged below the flow-limiting valve well; and the spring weir is arranged on the left side of the sand trap. By virtue of a trash rack and the sand trap, the intercepting well can conveniently dredge a channel so as to prevent a pipeline from getting blocked, and the well can avoid accumulation of sand therein so as to enhance an intercepting effect; by virtue of the spring weir, the influence of a conventional fixed weir on flood drainage of the channel in rainy seasons is avoided; the hydraulic automatic spring weir is arranged inside the confluence channel, and a weir plate is made from bendable high-strength stainless steel. When the weir is used for intercepting in dry seasons, the weir plate is arranged in an 'upright' mode to form a retaining weir so as to prevent outer river water from flowing backwards and to guarantee sewage intercepting; in the rainy seasons, under the hydraulic action of rain and flood in the channel, the hydraulic automatic spring weir 'lies flat' so as to achieve normal flood discharge; and by virtue of the flow-limiting valve well, the intercepting well can prevent excessive rainwater in the rainy seasons from entering a sewage pipeline, so that the load on a downstream pipeline is relieved.
