PURPOSE: A drain system is provided to reduce water loads applied to a construction structure by securing smooth drainage, thereby improving the endurance of the construction structure. CONSTITUTION: A drain system comprises a permeable drain way and one or more first sumps(120). The permeable drain way is arranged on an upper slab(21) of a construction structure installed in the ground and buried with a soil layer placed on the upper slab, and the permeable drain way comprises a gabion frame(111) and a geosynthetics mat(113). The first sumps are installed on the upper side of the permeable drain way within the soil layer. |
