  The one disclosed in Japanese Patent Application Laid-Open No. 2003-47346 can be laid continuously on a building rooftop or a parking lot by connecting a planting container for greening, and is optimal for inexpensive greening with water retention and heat insulation effects. Concerning planting containers, a plurality of storage walls are erected on the bottom peripheral surface where the connecting part is drilled to form a concave storage tank, and a plant protection support pillar that is horizontally supported by connecting ribs is integrated. It is the planting container for tree planting which laminated | stacked the cultivation soil and mulching material which consist of a water quality adjusting material, an artificial lightweight aggregate, and planted lawn etc. in each storage tank of the cultivation container formed specifically.

  In the case of this planting container for tree planting, it is the support pillar 4 or the intermediate support pillar 10 that transmits a vertical load such as a wheel load to the installation surface. Therefore, the distance between the support column 4 and the protrusion 21 is about 300 mm, which is larger than the vertical and horizontal dimensions of the shoe sole and the tire width. When a person walks at this interval, the shoe sole comes off the support column and enters the storage tank, and when the vehicle travels, the tire enters the storage tank. In any case, the soil put in the storage tank will be compacted, and good planting such as lawn cannot be expected.

  In order to prevent the soil that has been put in the planting space from being compacted even if a person or a vehicle passes through the planting container, the support columns must withstand the load and do not buckle. It is necessary to set an interval at which the shoe sole and wheels do not enter. Moreover, in order to guarantee the favorable growth of the planted plant, it is necessary to continue the water replenishment to the planting space.
