Description

Technical Field

[0001] This utility model belongs to the field of urban greening and planting technology, and in particular relates to a tree pit structure. Background Technology

[0002] Currently, due to increasingly scarce urban land and limited road widths, especially in old urban areas or commercial districts, the limited space must prioritize the basic functions of sidewalks, non-motorized vehicle lanes, and various municipal facilities. This often results in extremely limited underground space for planting roadside trees and other greenery, making it difficult to meet the required tree pit sizes and the needs of tree root growth during urban greening. Furthermore, the limited underground space is frequently disrupted by municipal construction, leading to high levels of construction waste such as broken concrete fragments in the soil of roadside and plaza green areas. This results in poor soil quality, high pollution levels, and a tendency to compact, severely impacting the healthy growth of tree roots and causing serious problems such as missing roots, sparse roots, uneven root growth, and even root rot.

[0003] Although urban greening planting standards have requirements for tree pits, the phenomenon of "large trees in small and shallow pits" is difficult to avoid in urban greening. Moreover, the tree pits dug by traditional greening tree planting methods are all "isolated" tree pits. In the poor soil and narrow underground environment of urban roads and squares, this further restricts the extension and development of the root system. This not only weakens the growth of green trees, but also makes the roadside trees prone to falling over in strong winds, seriously endangering pedestrians and vehicles. Utility Model Content

This not only improves the assembly efficiency and structural strength of the main component 1, but also reduces material usage, lightens the overall weight, facilitates transportation and installation, and ensures the stability and durability of the tree pit in the complex underground environment of the city.

[0055] Optionally, the overall height of the main component 1 can range from 60 to 120 cm, such as 60 cm, 62 cm, 68 cm, 74 cm, 81 cm, 92 cm, 96 cm, 103 cm, 115 cm, or 120 cm. The choice can be made based on actual needs and is not limited here.
