Description

Technical Field

[0001] This utility model relates to the technical field of tree maintenance, and more specifically, to a tree root-inducing and root-fixing device. Background Technology

[0002] Street trees are trees planted along roadsides and medians. They not only provide shade for vehicles and pedestrians but also create unique streetscapes, playing many important roles such as beautifying the environment, providing shade, reducing noise, and fixing carbon and releasing oxygen. On the one hand, street trees are prone to falling over due to their own growth conditions, lack of post-maintenance, and severe weather such as strong winds and heavy rains. On the other hand, many street trees with extensive root systems (such as banyan trees) cause varying degrees of damage to sidewalk paving, surrounding buildings, and underground pipelines due to limited underground growth space, seriously endangering the lives and property of nearby residents and passersby.

[0003] The prior art discloses a root-fixing device for roadside trees, including a planting box and a guide box. The planting box is detachably installed on the upper end of the guide box. The planting box includes a support frame, a planting plate, an annular top plate, and an outer cylinder. Planting plates are fixedly installed on all four sides of the support frame, forming a planting cavity that extends through both the upper and lower ends of the support frame. Several first through holes are opened on the surface of the planting plate. The annular top plate is fixedly installed on the upper end of the support frame. The outer cylinder is fitted onto the outside of the support frame, and the upper end of the outer cylinder is fixedly connected to the annular top plate. The outer cylinder, the annular top plate, and the planting plate together form a downward-opening inner cavity. The guide box includes a guide cylinder and a support plate. The support plate is fixedly installed on the upper end of the guide cylinder, forming a cavity that extends through both the upper and lower ends of the guide cylinder. A second through hole is opened on the support plate, and both the planting cavity and the inner cavity can be connected to the cavity through the second through hole. Several annular baffles are fixedly installed at intervals along the height direction on the inner surface of the guide cylinder. Several drainage holes are provided on the surface of the guide cylinder at the annular baffles along the circumference of the guide cylinder. In this scheme, planting boxes are used to cultivate roadside tree seedlings, and then the planting boxes and guide boxes are fixedly connected to complete the transplanting. The device requires a large burial depth, and for roadside trees, the underground space is limited, so this device is not suitable. Utility Model Content
