PURPOSE: A drain belt and a subsurface water drain apparatus using the same are provided to improve discharge capacity of the subsurface from the ground by forming a drain belt including a slit groove. CONSTITUTION: A drain belt(100) comprises a plate(110), a drainage hole(120), and a slit groove(130). The plate is made of flexible material. The drainage hole is formed on the inner side of the plate at regular intervals. The slit groove is formed to correspond to the drain hole and lets the subsurface water to flow in. The slit groove has fixed curvature and is symmetrical from the surface of the plate and to the connection part of the drain hole. The drain hole and the slit groove have the diameter of the fixed rate. |
