Construction method for minimally invasive breaking of anti-skid constraint of butt strap behind bridge abutment in seamless reconstruction of bridge

The invention discloses a construction method for minimally invasive breaking of anti-skid constraint of a butt strap behind a bridge abutment in seamless reconstruction of a bridge. The construction method comprises the steps that 1, the positions of all anti-skid steel bars are ascertained; 2, in the width range of the first batch of construction lanes, the peripheries of the corresponding anti-skid steel bars are broken through a core drilling machine, and the parts, located above abutment cap beams, of the anti-skid steel bars are exposed; 3, cutting off the part, above the abutment cap beam, of the anti-skid steel bar; 4, for the width range of other unconstructed lanes, before the bridge deck structure of the first batch of constructed bridge is closed and converted into a seamless bridge deck continuous system, the anti-skid constraint of the corresponding anti-skid steel bars on the bridge abutment rear butt strap is relieved; and 5, cutting off the parts, above the abutment cap beam, of the correspon
