A drainage guide system of a drain pipe is provided to prevent the subsidence or inundation of a structure such as a road and facilities constructed on a slope by separating effectively the soil falling down along a drainageway from a slope for the formation of a road or a housing lot by a local rainfall. A drainage guide system of a drain pipe is formed by forming an assembly support on a guide wall forming an inflow section(80), forming a screening block formed by assembling a horizontal body and a vertical body in the inflow section integrally, connecting a sedimentation tank connected with a drainageway(52), forming a sedimentation portion and a filtration portion, separating the sedimentation portion and the filtration portion in the rate of workability by assembling a filter plate provided with a filter hole into an assembling groove, and forming a soil passing section on the lower part of the filter plate. |
