[Problems to be solved by the invention] However, the drain pipe provided on the retaining wall has a diameter of 50 mm to 1 mm depending on the site.
Since the diameter of the drainage pipe differs between steps of 00mm, it is necessary to prepare lumber processed in accordance with the diameter of the drainage pipe each time, and it is dangerous if it is not tightly fitted into the drainage pipe. However, there is a problem that the drain pipe may be damaged. In addition, since the drainage pipe is generally inclined downward, the inserted timber also inclines and lacks stability as a scaffold, so a more horizontal stay must be installed on this timber. It was very troublesome.
