A water-retaining ecological tree pit for urban roads

Abstract

This utility model discloses a water-retaining ecological tree pit for urban roads, comprising a circular tree pit composed of two semi-circular tree pits joined together; a rectangular planting trough vertically located at the center of the semi-circular tree pit; a fan-shaped rubber sheet disposed at the lower interior of the semi-circular tree pit; infiltration pipes evenly distributed on the fan-shaped rubber sheet; an L-shaped water collection pipe disposed within the rectangular planting trough; and a square annular water collection hopper disposed within the square annular tree pit formed by several curb stones. This utility model utilizes the square annular water collection hopper to collect rainwater and guide it into the two semi-circular tree pits, then through infiltration pipes, greatly improving the utilization rate of rainwater. The elastic deformation of the fan-shaped rubber sheet itself prevents stress from being completely transferred to the rigid tree pit, ensuring the stability and aesthetics of the tree pit during long-term use.
