Greening watering system under highway bridge

Abstract

The invention discloses a greening watering system under a highway bridge. The greening watering system under the highway bridge comprises a road surface and a halving zone, a median strip is arrangedin the middle of the road surface and extends in the length direction of the road surface; a water collecting tank is formed in the position, below the median strip, of the road surface; the water collecting tank is connected with the bottom of the road surface; drain holes are formed in the two sides of the road surface; pipelines are arranged below the drain holes, one end of the pipelines communicates with the drain holes, the other end of the pipelines communicates with the water collecting tank, dewatering holes for water to flow out are formed in the bottom of the pipelines, the pipelines is evenly distributed in the length direction of the median strip, and the dewatering holes are evenly distributed in the length direction of the pipelines. The problem that in original rainy days,rainwater directly flows down from an opening of a median strip, the water amount in the lower range of the median strip is increased seriously, and other places are still dry is solved.

Description

technical field [0001] The invention relates to highway greening maintenance, in particular to a highway bridge greening sprinkler system. Background technique [0002] Highway bridges are built specifically for highway vehicle and pedestrian traffic. Made of steel, reinforced concrete or wood, a road bridge is designed for heavy rolling loads of up to 8,000 tons (80,000 tons), crowds. The width of the driving section depends on the expected intensity and speed of the traffic and the shape and span of the bridge (typically 7-21m). The walkway is at least 1m wide. [0003] There is greenery planted under the highway bridge, but the watering of the greenery has always been a problem. First, in rainy days, the rainwater usually flows downward through the opening of the middle zone in the middle of the expressway, causing a serious increase in the water volume under the middle zone, while other The problem that the place is still dry; second, the greening and watering maintena...
