The method for guiding the drainage of leachate of a crack in concrete comprises the steps of forming a filter mounting hole(52) on the appointed part of a crack(51) in concrete(50), forming a packing mounting hole(53) on the surface of the concrete from the filter mounting hole to a concrete bottom drainageway, filling up the crack in the concrete with repair materials, coating the surface of the filter mounting hole and the packing mounting hole of the concrete with waterproof materials, inserting a leachate filter(1) to the filter mounting hole, and installing a drainage guidance packing(40) provided with a passage groove(41) to the inside of the packing mounting groove elastically. The leachate filter comprises a filter supporter installed to the filter mounting hole of the concrete, a filter body inserted to the filter supporter and provided with a filter housing hole, and a filter medium placed in the filter housing hole of the filter body to filter out leachate. |
