It is formed by waterproofing the roof of a concrete building and putting artificial soil into the waterproofed surface and planting. However, when planting on an inclined surface, the soil flows out downward due to rainfall or the like, so that the planting garden cannot be maintained. For this reason, in the case of the inclined artificial ground, it is generally practiced to form a retaining wall and plant on a stepped surface.

Since the movement of the adjacent hollow pipes can be restricted, the soil 13 at the construction site can be stably held. Also, unlike the earth retaining, the planting slope does not become stair-like,
In accordance with the height of the water-permeable hollow tube, the soil 13 can be held at a thickness along the inclined surface, and a natural landscape can be obtained by planting. Therefore, even in a roof garden where lightness is required, even if the soil layer is made thin, a uniform soil layer having a relatively gentle slope can be formed.
