Composite ecological gallery bridge with pedestrian and animal migration functions

The utility model relates to the technical field of ecological bridges, in particular to a composite ecological gallery bridge with pedestrian and animal migration functions, which comprises first bridge piers and first bridge deck slabs, the first bridge piers are parallelly and oppositely inserted on the ground of a plant area, the first bridge deck slabs are erected on the bridge piers, and blind pipes for drainage are arranged on the lower portions inside the bridge deck slabs; second bridge piers which are parallel and opposite to each other are arranged above the first bridge deck slabs, and second bridge deck slabs for people to walk are erected on the second bridge piers. By means of the design, the device can be fully suitable for utilizing an existing forest food network mechanism to preferentially repair habitats on the two sides. Through a low-interference strategy, sustainable feeding between mountains and cities and between people and nature is realized. The ecological function of tandem wild an
