Abstract

The utility model discloses a river course box culvert with distribution of rain and sewage and overflow function, it is including the box culvert body (1), overflow weir (2) and vatch basin (3), the box culvert body (1) is rectangular shape box, establish two overflow weir (2) side by side along (1) two inside wall of the box culvert body, overflow weir (2) highly are less than the internal lateral wall of box culvert, constitute sewage passageway (5) between overflow weir (2) and the internal lateral wall of box culvert, constitute flood passage way (6) of river circulation between two overflow weir (2), the both ends of sewage passageway (5) are sealed, and the excavation has vatch basin (3) under the stratum of the lower one end in position wherein, set up drill way (4) of introducing the rainwater on the box culvert body (1) lateral wall. The utility model discloses the advantage of utensil is: realized that sewage and initial stage rainwater through holding back the separation, reduce sewage and get into in the river, and simple structure, economical and practical have solved domestic sewage and initial stage rainwater to the problem of river pollution, the while during torrential rain flood passage not influenced.

Description

A kind of river course box culvert with rain dirt shunting and relief function

Technical field

This utility model belongs to town sewage and controls and the technical field of stream protection, is specifically related to a kind of river course and contains ditch.

Background technology

Along with the quickening of Development of China's Urbanization, Southwestern China most area river pollution is serious.The village of medium or smallsized river bank, suburb municipal administration blowdown pipe network facilities are not built, and cause sanitary sewage directly to drain into korneforos.City flow of the people is big, and mankind's activity is intensive, and Route coverage is high, under the souring of rainfall, easily brings the pollutant remaining in earth's surface into water body, causes the pollution of urban river；The widespread pollution from the overuse of fertilizers and pesticides in rural area in villages and small towns, the human and animal excreta in rural area, fertilizer and pesticide confuse rainwater, irrigation water and enter river together, cause a certain degree of pollution.

River passes through a section of city, and open channel is often substituted by closed conduit.Still some enters closed conduit by municipal sewage arm the city domestic sewage of river alongshore, early-stage rainwater etc., severe contamination water quality of river.

Utility model content

The problem that canal causes water quality of river to deteriorate is entered in order to the sewage solving to presently, there are, early-stage rainwater are in line, technical problem to be solved in the utility model is just to provide a kind of river course box culvert, it can along river course by sewage and early-stage rainwater through retaining separation, reduce sewage and enter in river.

Technical problem to be solved in the utility model is realized by such technical scheme, it includes box culvert body, downflow weir and Vatch basin, box culvert body is strip casing, two downflow weirs are set up side by side along box culvert body two medial wall, height of weir plate is less than sidewall in box culvert body, sewage routeway is formed between sidewall in downflow weir and box culvert body, the flood passage road of river circulation is constituted between two downflow weirs, the closed at both ends of sewage routeway, and excavation has Vatch basin under the stratum of one end that position is relatively low wherein, box culvert body sidewall offers the aperture introducing rainwater.

Operation principle of the present utility model is: during dry season, river flows in flood passage road, sanitary sewages etc. enter in sewage routeway by the aperture on box culvert body sidewall, existence due to downflow weir, sewage will not mix with river, sewage flow to Vatch basin, and sewage is also delivered to Sewage Plant by soil pipe and processed by Vatch basin intercepting sewage.

During rainy season, at the rainfall initial stage, sanitary sewage and early-stage rainwater etc. are by, in the aperture entrance sewage routeway on box culvert body sidewall, flowing to Vatch basin, and Vatch basin gets up sewage collecting, delivers to Sewage Plant by soil pipe and processes.During heavy rain, along with the increase of rainfall, the water level in sewage routeway slowly raises, and its water quality improves, and when water level is increased to height of weir plate, in stormwater overflow to flood passage road, enters in river.

So, this utility model has the advantage that and achieves sewage and early-stage rainwater through retaining separation, reduces sewage and enters in river；And structurally simple, economical practicality, solving sanitary sewage and the early-stage rainwater problem to river pollution, during heavy rain, flood passage is unaffected simultaneously.

Accompanying drawing explanation

Accompanying drawing of the present utility model is described as follows:

Fig. 1 is structural representation of the present utility model；

Fig. 2 is profile of the present utility model.

In figure: 1. box culvert body；2. downflow weir；3. Vatch basin；4. aperture；5. sewage routeway；6. flood passage road.

Detailed description of the invention

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:

As depicted in figs. 1 and 2, this utility model includes box culvert body 1, downflow weir 2 and Vatch basin 3, box culvert body 1 is strip casing, two downflow weirs 2 are set up side by side along box culvert body two medial wall, downflow weir 2 height is less than sidewall in box culvert body, sewage routeway 5 is formed between sidewall in downflow weir 2 and box culvert body, the flood passage road 6 of river circulation is constituted between two downflow weirs 2, the closed at both ends of sewage routeway 5, and excavation has Vatch basin 3 under the stratum of one end that position is relatively low wherein, box culvert body 1 sidewall offers the aperture 4 introducing rainwater.

Above-mentioned box culvert body 1 is made up of concrete, and downflow weir 2 is concrete walls.This utility model is suitable for small rivers, it is also possible to build sewage routeway along two sides, great river, it is achieved sewage does not enter flood passage road.

Claims

1. a river course box culvert with rain dirt shunting and relief function, include box culvert body (1), downflow weir (2) and Vatch basin (3), box culvert body (1) is strip casing, it is characterized in that: set up two downflow weirs (2) side by side along box culvert body (1) two medial wall, downflow weir (2) height is less than sidewall in box culvert body, sewage routeway (5) is formed between sidewall in downflow weir (2) and box culvert body, the flood passage road (6) of river circulation is constituted between two downflow weirs (2), the closed at both ends of sewage routeway (5), and excavation has Vatch basin (3) under the stratum of one end that position is relatively low wherein, the aperture (4) introducing rainwater is offered on box culvert body (1) sidewall.
