PURPOSE: A coupling structure for a drain board is provided to reduce time required for coupling a drain board and a geotextile by forming a coupled part to be short. CONSTITUTION: A coupling structure for a drain board comprises a drain board(10), a geotextile(30), and protrusions(20). The drain board is formed in the bottom surface of an underground layer to form drainage canals(16). The geotextile is formed on a surface in which the drainage canals are formed. The protrusions are formed in both side ends of the drain board and are in contact with the geotextile. |
