A drainage guide system for a drainpipe is provided to prevent the danger of burying and overflowing a drainageway with wood wastes coming down along rainwater pouring down, and to prevent the inundation of soil or gravel coming down according to the rainwater pouring down heavily. A drainage guide system for a drainpipe is formed by assembling a coupling rib of an arc-shaped guide bar(70) integrally to a safety rib(71) of two side walls(61,62) formed in the downward direction of an incline and forming an inflow section, assembling a filter plate formed to be projected to the coupling rib with another safety rib(72) of a drainageway, and forming a filter on the filter plate. |
