In addition, since the footpath and the roadway are not broken by the uprooting, it is not necessary to perform maintenance such as repairs that have been necessary until now. In addition, the size of the tree can be adjusted like a tree planted in a flowerpot, which is useful for improving the landscape of the city, such as making the size of street trees uniform.

Also, if a major disaster occurs due to an earthquake, etc., the roadside trees etc. do not need their original functions (improving the cityscape, securing the shade of pedestrians, etc.), so only the restoration material 1 is taken out from the ground, It will be used for road restoration as a disaster recovery material. At this time, the tree 30 is cut or left in the same place as it is.
When the restoration material 1 is taken out from the ground, in the case of the rotary penetrating pipe 1a having the blades 8, it can be easily pulled out by rotating in the reverse direction. Further, in the case of the restoration material 1 having no wings, it can be taken out by reducing peripheral friction by rotation, vibration, vibro, water jet or the like (the same applies to other embodiments).

  Then, when Japan is restored later, the temporary restoration material 1 can be dismantled and installed on the sidewalk again and planted with trees 30 to prevent rooting. In addition, when it cannot be reused because it is continuously used for roads, etc. or is cut off, a new restoration material 1 is buried separately.

  According to the present embodiment, the tubular restoration material 1 installed in the ground is always planted with trees 30 and the like, and functions as a roadside tree, etc. In an emergency, the disaster recovery can be promoted by taking it out from the ground and using it as a disaster recovery material.
