Operation highway tunnel pavement arching and cracking treatment structure

The utility model relates to the field of operation highway tunnel maintenance, in particular to a reinforcing and treating structure for arching and cracking of an operation highway tunnel pavement. Comprising feet-lock anchor pipes, grouting pipes, longitudinal channel steel, transverse channel steel, self-propelled anchor rods, steel reinforced concrete, a reinforced concrete pavement subbase, a concrete base and a pavement asphalt layer. The construction sequence is as follows: firstly, foot-lock anchor pipes of arch feet on two sides of a tunnel are arranged to prevent the tunnel from deforming due to subsequent construction; after the pavement and the tunnel bottom are excavated to the designed elevation, tunnel bottom grouting is conducted, self-propelled anchor rods are installed, longitudinal and transverse channel steel combination forming steel frames are welded and connected with the self-propelled anchor rods, steel reinforced concrete is poured, then a pavement reinforced concrete subbase layer
