Abstract: The present invention relates to a drain induction method using a perforated drainpipe having a triangular cross section, which is a drain method for reducing water pressure generated in a rear part of a retaining wall, which is a main cause for the collapse of an existing reinforced soil retaining wall of civil-engineering works. Water pressure generated on the rear side of a retaining wall can be generated due to a natural rainwater permeation condition or other conditions such as a poor compacting state of retaining wall backfilling, a geographical underground water level and the like, and the water pressure can cause the deformation of a masonry type form of panel blocks or prefabricated blocks of a reinforced soil retaining wall by increasing a water level on the rear side of the retaining wall, which can lead to collapse having a risk due to the imbalance of the wall. Water stagnating on the rear side of a retaining wall is naturally drained at all times through a drainpipe to remove water pressure, and an outlet, which is morphologically difficult to make on a panel surface or a block of an outer wall surface of a retaining wall, is made into a small triangular shape such that applicability can become higher. In other words, the present invention is a drain method using a triangular drainpipe.
