The utility model relates to the technical field of tunnel construction, and discloses a tunnel drainage side ditch structure. The tunnel drainage side ditch structure comprises a ditch body, the ditch body comprises a bottom face and side faces oppositely arranged on the two sides of the bottom face, a cavity used for drainage is defined by the bottom face and the opposite side faces on the two sides of the bottom face, and an opening is formed in the position, between the opposite side faces, of the top of the cavity; wherein at least one side face is provided with an inclined face inclining towards the other side face in the vertical direction, and the width of the opening is smaller than that of the bottom face through the inclined face. According to the tunnel drainage side ditch structure, the opening width of the drainage ditch can be reduced on the premise that the drainage capacity is guaranteed, so that the width of a tunnel is reduced, and investment is saved. 本实用新型涉及隧道施工技术领域，公开了一种隧道排水边沟结构。隧道排水边沟结构
