The backflow-preventing sewage intercepting well comprises a well body, wherein the interior of the well body is hollow; the well body has a certain volume; an overflow weir is arranged in a middle area of the well body so as to divide the inner cavity of the well body into a water inlet cavity and an overflowing water discharging cavity; at least one confluent pipe for guiding a mixed rainwater and sewage water flow into the water inlet cavity is connected onto the side wall of the well body; a sewage intercepting pipe is also connected onto the side wall of the well body on one side of the water inlet cavity; and an overflowing water discharging pipe is connected onto the side wall of the well body on one side of the overflowing water discharging cavity. Compared with the conventional sewage intercepting wells home and abroad, the backflow-preventing sewage intercepting well has the advantages as follows: the backflow-preventing sewage intercepting well has a function of preventing backflow of river water; the volume of the well body is small, so that the backflow-preventing sewage intercepting well is applicable to a place with a narrow river bank space; the backflow-preventing sewage intercepting well is simple in structure and convenient to construct; and the construction cost can be reduced easily.
Description
Technical field
The present invention relates to a kind of catchpit, more specifically say a kind of reverse-filling sewage catchpit.
Background technology
Catchpit is maximum a kind of facility of using in the present municipal sewage treatment, some are produced the cloudy well that pollutes focuses in a bite well, well leads to Wastewater Treatment Plant thus, if there is not this well, want sewage and enter Sewage Plant, just must all enter Wastewater Treatment Plant by every pipe, and in front with regard to these sewage that dam with a bite well, pipeline to Wastewater Treatment Plant will greatly reduce, and also is beneficial to collection sewage.Some at present domestic catchpit volumes are large, complex structure, and do not have the function of reverse-filling, particularly rainy day, river pours in down a chimney to come in easily.
Summary of the invention
The object of the present invention is to provide a kind of reverse-filling sewage catchpit, reverse-filling sewage catchpit of the present invention is compared with existing sewage catchpit both domestic and external, not only has the function that prevents that river from pouring in down a chimney; Well body volume is little, is applicable to the place of river levee narrow space; Simple structure, easy construction also helps the reduction construction costs.
Technical program of the present invention lies in: a kind of reverse-filling sewage catchpit, the well body that comprises inner hollow and have a constant volume, the central region of described well body is provided with overflow weir, so that the well intracoelomic cavity is divided into intake antrum and Overflow drainage chamber, be connected with at least 1 collecting fitting that is used for introducing to intake antrum the dirty mixed flow of rain on the described well body sidewall, be positioned at also to be connected with on the well body sidewall of intake antrum one side and cut dirty pipe, be positioned on the well body sidewall of Overflow drainage chamber one side and be connected with relief sewer.
In one embodiment, the invert elevation (IE) of described collecting fitting is a little more than the invert elevation (IE) that cuts dirty pipe.
In one embodiment, be provided with cover plate in the upper shed of described well body.
In one embodiment, described cover plate is reinforced concrete cover plate.
In one embodiment, described cover plate comprises seat slurry, ductile iron anti-stealing manhole cover and well seat.
In one embodiment, described well body adopts steel concrete to build to form.
In one embodiment, also be equipped with one deck C15 element concrete bed course below the described well body.
In one embodiment, described well body adopts cement mortar and fly ash brick to be built into.
In one embodiment, the rubble that also is equipped with one deck below the described well body is filled with sand cushion and one deck natural sand bed course.
In one embodiment, described height of weir plate satisfy the overflow weir top mark tall and big in fine inland river at the incoming tide overflow well go out pool level and add again 15 ~ 30cm.
Reverse-filling sewage catchpit of the present invention is compared with existing sewage catchpit both domestic and external: the one, and catchpit of the present invention has the reverse-filling function, and the river that has solved catchpit pours in down a chimney problem.The 2nd, because the limited space of river levee, the space that the well body is set is relatively more nervous, and well body volume of the present invention is little, is applicable to the place of river levee narrow space, has solved the construction space problem.The 3rd, catchpit simple structure of the present invention, only at one overflow weir of inner chamber setting, easy construction, and be conducive to protect fragile river levee.The 4th, catchpit overall structure of the present invention is simple, cheap, is conducive to reduce the construction works cost.
