Bridge crash barrier prefabricated planter and construction method thereof

The invention is suitable for the technical field of urban bridges and landscape design, and provides a bridge crash barrier prefabricated planter and a construction method thereof. The bridge crash barrier prefabricated planter comprises a plurality of sections of prefabricated planters, the prefabricated planters are arranged in the longitudinal direction of the bridge crash barrier, and each section of prefabricated planter comprises a reinforced concrete prefabricated planter body, a plurality of planter rib plates, a plurality of planter transverse partition plates, a planter water storage pool, a plurality of water absorption capillary cloth strips and permeable geotextile. According to the prefabricated planter, a planter plant automatic irrigation micro-system is established on anexisting bridge crash barrier, rainwater resources are recycled, and the urban bridge landscape effect is improved. Meanwhile, the prefabricated planters are directly spliced and installed on the outer side of an existing bri
