Method for carving groove in cement concrete pavement

The invention discloses a method for carving a groove in cement concrete pavement. The method comprises the following steps that a pavement base layer is laid; a first cement concrete layer is laid on the pavement base layer, and then groove carving nets are laid in sequence and rolled through uniform force; after the first cement concrete layer is subjected to first solidification, a layer of PVC adhesives is sprayed on the upper end face of each groove carving net, and the PVC adhesives are not sprayed on strip piece bodies; a second cement concrete layer is laid on the first cement concrete layer, and the radian of the second cement concrete layer is adapted to the height of the strip piece bodies of the upper end face of the groove carving nets; and after the second cement concrete layer is subjected to first solidification, the strip piece bodies on the groove carving nets are removed, and pavement carved grooves are formed, polished, finished and washed through water, so that the formed pavement carved grooves are accurate and clear. The method is simple in construction, and the forming effect of the pavement carved grooves is good. By holding the groove carving nets fixing the strip piece bodies, anti-crack performance of the cement concrete pavement can be further improved, and the service life of the pavement is prolonged.
