Description
Technical Field
The utility model relates to a highway engineering specifically is a road surface runoff evaporation pond.
Background
When the highway is close to water bodies with higher water quality requirements such as water source protection places, domestic drinking water sources and the like, road surface runoff (including road surface runoff formed by rainwater and road surface runoff formed by leaked dangerous chemicals) easily flows into the water bodies and causes water body pollution, so that the human health is seriously harmed. Therefore, the invention is needed to provide a pavement runoff evaporation pond to solve the problem that pavement runoff flows into a water body and causes water body pollution.
Disclosure of Invention
The utility model discloses a solve road surface runoff and flow into the water and cause water pollution's problem, provide a road surface runoff evaporation pond.
The utility model discloses an adopt following technical scheme to realize:
a pavement runoff evaporation tank comprises an evaporation tank body; the bottom wall of the evaporation tank body is a horizontal wall; the front side wall of the evaporation tank body is a slope wall with a high front part and a low back part; the rear side wall of the evaporation tank body is a slope wall with a high rear part and a low front part; the left side wall of the evaporation tank body is a slope wall with a high left side and a low right side; the right side wall of the evaporation tank body is a slope wall with a high right and a low left; a water blocking weir and an isolation grid are arranged on the edge of the evaporation tank body in a surrounding manner; the section of the water blocking weir is trapezoidal; the isolation fence is positioned on the outer side of the water blocking weir, and the height of the isolation fence is greater than that of the water blocking weir; a drainage ditch is dug on the right tank edge of the evaporation tank body; the drainage ditch penetrates through the lower part of the water retaining weir and the lower part of the separation fence, and two ends of the drainage ditch are respectively connected with the right side wall of the evaporation tank body and the road surface; the front part of the left side wall and the rear part of the right side wall of the evaporation tank body are respectively provided with a step; the upper ends of the two steps are respectively connected with the left pool edge and the right pool edge of the evaporation pool body; the lower extreme of two marks time all links up with the diapire of evaporation pond body.
During the use, the road surface runoff from highway road surface flows into the evaporation pond body through the escape canal, realizes the collection of road surface runoff from this. If the collected road surface runoff is rainwater, the rainwater is allowed to evaporate naturally. If the collected road surface runoff is the leaked dangerous chemicals, the highway management personnel timely arrive at the site to transfer the dangerous chemicals in the evaporation tank body into the emergency tank car for outward transportation treatment. In the process, the water-stopping weir is used for preventing rainwater or dangerous chemicals in the evaporating pond body from overflowing. The function of the isolation barrier is to prevent accidents caused by personnel or foreign objects falling into the evaporation pool body. The two steps are used for road management personnel to go down into the evaporation tank body for daily cleaning and maintenance.
Furthermore, an iron grate is arranged in the drainage ditch and is positioned below the isolation grid. When the filter is used, the iron grate is used for filtering large impurities in road surface runoff.
Based on above-mentioned process, a road surface runoff evaporation pond through adopting the brand-new structure, realized the collection and the processing of road surface runoff, effectively avoided road surface runoff to flow into the water and cause the water pollution from this to human health has effectively been protected.
The utility model discloses rational in infrastructure, design benefit have effectively solved road surface runoff and have flowed into the water and cause water pollution's problem, are applicable to highway engineering.
