PURPOSE: A drainage system for a bridge deck capable of facilitating a maintenance work is provided to improve workability by structurally preventing the blockage of a drainage way. CONSTITUTION: A drainage system for a bridge deck capable of facilitating a maintenance work comprises multiple inner drain parts, drain hanger parts(30), outer drain parts(70), and filter parts. The inner drain parts are installed on both edges of a slab(10) having barriers(12). The drain hanger parts touch packing contact protrusions(24) of the inner drain parts and coupled to the inner drain parts through bolts. The outer drain parts are integrally inserted into the drain hanger parts in a longitudinal direction to discharge rainwater and foreign materials from the inner drain parts to the outside. The filter parts are inserted into filter insertion protrusions of the inner drain parts and filter rainwater and foreign materials. |
