Environment-friendly bridge with easy sewage discharge

Abstract

The invention relates to an environment-friendly bridge with easy sewage discharge. The environment-friendly bridge with easy sewage discharge comprises a bridge body and a sewage discharge channel, and further includes straight drain pipes penetrating through the bridge body, wherein a sewage discharge pipe is connected to each straight drain pipe in a by-pass mode, and flow dividing devices are arranged at the joints of the straight drain pipes and the sewage discharge pipes; the flow dividing devices comprise fixing guide shafts, sleeves and flow dividing belts; the flow dividing belts comprise through flow dividing holes; the flow dividing belts comprise flow dividing surfaces and sewage discharge surfaces, one ends of the flow dividing surfaces are located in the straight drain pipes, and the other ends of the flow dividing surfaces extend into the sewage discharge pipes; and the horizontal heights of the flow dividing surfaces located at one ends of the straight drain pipes are higher than the horizontal heights located at one ends of the sewage discharge pipes, and both ends of the sewage discharge surfaces are located in the sewage discharge pipes. According to the environment-friendly bridge with easy sewage discharge, the structure is novel, the principle is unique, the environment of a bridge deck and a river channel below can be ensured, sewage discharge can be efficient, the area of water accumulation is reduced, and the smooth passage of cars and pedestrians is ensured.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge convenient for sewage discharge. Background technique [0002] At present, there are two sewage discharge methods for bridges. One is that the sewage on the bridge surface flows directly from under the bridge, which is called the direct discharge method; The sewage pipe is connected, and the sewage is collected into the sewage channel and then enters the underground pipe; the direct drainage method can quickly discharge the rainwater and sewage on the bridge deck, especially in summer continuous rain and heavy rain, which can effectively avoid excessive water on the bridge and avoid vehicle skidding , so as to effectively ensure the smooth passage of vehicles and pedestrians; however, this sewage discharge method will pollute the river environment under the bridge, and a lot of garbage and stains on the bridge surface will directly enter the river, affecting the river environment;...

[0002] At present, there are two sewage discharge methods for bridges. One is that the sewage on the bridge surface flows directly from under the bridge, which is called the direct discharge method; The sewage pipe is connected, and the sewage is collected into the sewage channel and then enters the underground pipe; the direct drainage method can quickly discharge the rainwater and sewage on the bridge deck, especially in summer continuous rain and heavy rain, which can effectively avoid excessive water on the bridge and avoid vehicle skidding , so as to effectively ensure the smooth passage of vehicles and pedestrians; however, this sewage discharge method will pollute the river environment under the bridge, and a lot of garbage and stains on the bridge surface will directly enter the river, affecting the river environment; another method can effectively avoid this. This kind of river pollution, but its sewage discharge efficiency is limited. In summer continuous rain and heavy rain, a large amount of rainwater will be stored in the bridge area, and overflow will also occur at the connection between the sewage channel and the underground sewage pipe, resulting in water accumulation at both ends of the bridge deck. become ill, seriously affecting the normal traffic of vehicles and pedestrians
