Integrated transverse ditch structure of tunnel

The invention belongs to the technical field of urban tunnel construction, and discloses a tunnel integrated transverse groove structure which comprises a transverse groove body formed in a tunnel bottom plate main body structure. The transverse groove body is in a form that the upper part is narrow and the lower part is widened, and is reinforced by groove body steel bars; a reinforced concrete layer and a reinforcing mesh are laid on the two sides of the transverse groove body, and the reinforced concrete layer is connected with the tunnel bottom plate main body structure through annular connecting steel bars; a drainage grate cover plate is arranged on the top face of the transverse groove body, and the two sides of the drainage grate cover plate are connected with the drainage grate base through fixing bolts. A safety buckle is arranged on the bottom face of the drainage grate cover plate and used for being meshed with the drainage grate base. According to the method, the structural form of the transverse
