Abstract
The present invention relates to a building method of sewage delivering engineering capable of preventing odour from diffusing and draining floodwater, which belongs to the field of environmental protection. The present invention is mainly characterized in that I-shaped overflow pipes for preventing odour from diffusing are arranged in at least one of vertical walls on both sides between the channel top and the riverbed surface which are adjacent to the sewage transmission engineering at certain intervals. Therefore, the present achieves the purposes that sewage is drained at ordinary times and the comprehensive utilization of floodwater drainage, bank protection, top planting beautification, sewage treatment, etc. is realized when floodwater comes and continuously rises through the I-shaped overflow pipes until rushing in the sewage delivering engineering.
Description
The present invention relates to a kind of foul smell that prevents and distribute and take into account the construction method of the sewage transport closed conduit that drains off floodwaters, belong to field of environment protection.
The existing at home and abroad sewage transport engineering (be called for short and cut dirty engineering) that prevents that foul smell from distributing comprises section dirty engineering that Beijing municipal engineering designing institute designs, and it is underground all to be provided in a side of bank, municipal sewage Xi He both sides traditionally.Because near the sewage small stream river of great rivers, its two sides are densely populated, building is stood in great numbers, and near limit, sewage small stream riverbank.This brings very big difficulty with regard to giving excavation and cast rectangular reinforced concrete channel, carries out vertical cut and have to adopt at each handful stain, and reinforced concrete is built well, and pointwise is tunneled down below then, and very pipe connects.This not only causes lot of materials waste and consumption worker consuming time, and the connection of underground driving, can only be circular pipeline with the cross section generally, and the diameter of pipeline is subjected to the various factors restriction that certain limitation is arranged, and can not effectively increase the capacity of blowdown.Interim season when heavy rain, heavy rain pours in buried underground pipeline together with various sewage, adds the jacking of sewage small stream river, outside high water level again, impeded drainage will occur, even the sewage refluence is overflowed.Even having only on one side, some place have sewage to enter sewage small stream river, only need to build a sewage transport channel, even there is being spacious place can freely open direct excavation, build up the rectangle sewage sealing conveying engineering of band grit chamber, and then earthing covers back, but the construction method of the sewage transport engineering that this anti-foul smell distributes still dislikes engineering quantity excessive, consumption worker consuming time, and be unfavorable for the comprehensive utilization of engineering particularly being unfavorable for taking into account the comprehensive utilization of drainning off floodwaters.
Purpose of the present invention is exactly will propose a kind of foul smell that prevents to distribute and take into account the construction method of the sewage transport closed conduit that drains off floodwaters, and it not only helps sewer at ordinary times, prevents that foul smell from distributing, and can also take into account when flood arrives and drain off floodwaters comprehensive utilization and reduce cost.
The object of the present invention is achieved like this: prevent that foul smell from distributing and taking into account the construction method of the sewage transport closed conduit that drains off floodwaters, comprise that section is that rectangle and outlet of sewer place have the single canal of traditional closed of insertion slot type sluice gate or the sewage transport closed conduit construction method of dual channel, it is characterized in that flushing substantially with two sides, also passing through the sewage transport closed conduit of name bridge block bottom surface, way, sewage small stream river bank, it arrives near the perpendicular wall in ground channel both sides, riverbed near the channel top, have at least on one side and erect in the wall, be provided with at a certain distance and prevent what foul smell distributed
The excessive flood pipe of shape.Like this, when storm flood arrives, what the flood level in sewage small stream river just can be in the perpendicular wall in the both sides of single canal sewage transport closed conduit of the sewage small stream korneforos heart
The dual channel sewage transport closed conduit that flood pipe or Xi He two sides double as shore protection river levee are used but shape is overflow erects in the wall on one side towards the korneforos heart
Shape is overflow, and the flood pipe is interior to rise, and drains off floodwaters together up to pouring in to carry in the closed conduit.Reach sewer at ordinary times, exceed standard when flood comes and can take into account and drain off floodwaters, and the top is gone up comprehensive utilizations such as plantation beautifies, disposes of sewage and reduced cost.
Further specify below in conjunction with embodiment and accompanying drawing.
Fig. 1 is the single canal drawing in side sectional elevation of the present invention; Fig. 2 is a dual channel drawing in side sectional elevation of the present invention.
Embodiment 1 sees that Fig. 1 has bridge 8 sewage small stream rivers 1, digs a little along the riverbed, center and just can build up single canal compound sewage conveying closed conduit 2 that section is the reinforced concrete channel of rectangle deeply, is provided with the seal cover 3 that can open desilting above at a certain distance.Be provided with in the perpendicular wall of the both sides reinforced concrete of sewage transport closed conduit and prevent what foul smell distributed
The shape flood pipe 4 that overflows, its lower end water inlet usually also are immersed under the clear water above the riverbed anti-foul smell and overflow.5 of tube connectors are communicated with the sewage transport closed conduit under the riverbed and are with the sewage draining exit of grit chamber 6 and blow-off pipe 7 with each.When storm flood from the upstream when rushed down in a torrent in the both sides of the center sewage transport closed conduit 2 in sewage small stream river.Flood level just can every 10 to 50 meters just respectively have an end opening from the riverbed face O.5-1 rice, suitable for reading from the top O.5-2 rice
Rise in the shape pipe 4, drain off floodwaters in pouring in the sewage transport closed conduit 2 that top flushes with two sides substantially along the line, reach sewer at ordinary times, two by-pass flow clear water can be taken into account the composite application that drains off floodwaters again during storm flood, kind of the flower of the holding concurrently comprehensive utilization such as beautify the environment of breeding fish.
Embodiment 2: as shown in Figure 2.The bank, both sides in sewage small stream river 1 is the sewage transport closed conduit 2 of the reinforced concrete channel of rectangle by the cast section, also carries closed conduit the same with traditional wastewater above it, is provided with the seal cover 3 of the desilting of being convenient to uncap at a certain distance.Two sides sewage transport closed conduit erects to be provided with in the wall towards small stream korneforos heart reinforced concrete simultaneously prevents what foul smell distributed
The excessive flood pipe 4 of shape, and each is with the sewage draining exit of grit chamber 6 and blow-off pipe 7 to be communicated with the bank by tube connector 5, admits and also carries sewage.When storm flood, flood level just can have as embodiment 1
The overflow one side of flood pipe 4 of shape constantly rises, and drains off floodwaters together in pouring in sewage transport closed conduit 2, reaches the purpose of comprehensive utilization similarly to Example 1, more than simultaneously the effect of individual shore protection, removed from building again in addition and protected river levee, thereby reduced cost on the whole.
