A drainage channel cover for heavy load is provided to reduce bending deformation or distortion to the minimum by having large bearing capacity against the load added from the upper part when heavy load vehicles or objects pass through. The invention relates to a drainage channel cover(100) for heavy load capable of having large bearing capacity against the load added from the upper part when heavy load vehicles or objects pass through and minimizing bending deformation or distortion by installing many support members(10) between a pair of side frames(110) at regular intervals, wherein the support member is formed by placing a support(13) in the middle of upper and lower support plates(12,14) integrally. |
