The utility model belongs to the technical field of
building design, and particularly relates to a
pedestrian overpass with rainwater collection and ecological
greening functions, ceilings are arranged above a bridge body structure and a channel structure,
water tanks are arranged on two sides of the bridge body structure in the length direction, the
water tanks are connected with a flow discarding device, and the flow discarding device is connected with a water tank. Planting grooves are formed in the two sides, in the length direction, of the bridge body structure and the channel structure, the planting grooves are connected with a flow abandoning device and further connected with an urban drainage
system, elevators are arranged at the two ends of the bridge body structure so that people with obstacles can walk together conveniently, ramps are arranged on the channel structure so that bicycles and the like can be pushed to pass through conveniently, and the flow abandoning device is connected with a water collecting
pool. According to the overbridge, rainwater can be collected to irrigate green plants, the requirement for urban
tap water is reduced, the overbridge is more attractive,
ambient air can be purified, the temperature of the overbridge and the ambient temperature can be adjusted, and barrier-free passing is met.
