A drainage channel cover for heavy load is provided to reduce deformation to the minimum by having large bearing capacity against the load added from the upper part when heavy load vehicles or objects pass through harbors, an airport, a physical distribution base or a wide road. The drainage channel cover(100) for heavy load, for minimizing deformation by having large bearing capacity against the load added from the upper part when heavy load vehicles or objects pass through harbors, an airport, a physical distribution base or a wide road, is formed by welding many support members(10), which are formed by integrating folding segments(14) with the top and bottom of vertical bars(12), between a pair of side frames. Hereon many auxiliary drain holes are formed on the folding segments of the support member to drain off water more smoothly. |
