法が採られていた。
Traditionally, in order to plant a tree, a root ball with a wrapped root is inserted into a root hole that is pre-drilled in the ground.
In addition to burying soil in the root hole cavity, a method was used in which a wooden support was fixed to the trunk to prevent it from tipping over, or a branch line anchored in the ground was used for support.
ところが、このような従来方法では、傾倒防止

隘な街路樹木等の植立を可能としたものである。 This is a root hole H drilled into the ground as shown in the diagram.
The root ball 22 with the root wrapping 21 inside is inserted and placed on the bottom B of the root hole, and the belt 25 wrapped around the root 24 is connected to the anchor 26 driven into the soil to close the root hole. The soil is buried in the void, making it possible to support the tree when it is upright without installing supporting means such as tree supports or branch lines on the ground to prevent it from tipping over, making it possible to plant street trees in narrow spaces. That is.
しかしながら、この樹木植立方法においては、
樹木が大型になると樹木の自重で根穴底部Ｂが沈
