Construction method of shear resistance and strengthening of concrete box beams based on corrugated steel webs

The invention discloses a construction method of shear resistance and strengthening of concrete box beams based on corrugated steel webs. The construction method successively comprises the following steps: performing construction lofting and positioning on top plates and bottom plates of box beams; performing and strengthening bonding surfaces; drilling anchor bolt holes in the bottom surfaces of the top plates of the box beams; drilling holes and planting steel bars in the top surfaces of the bottom plates of the box beams; performing laying-off on the corrugated steel webs; drilling holes and performing polishing on upper flange plates; welding and mounting the corrugated steel webs; mounting reinforced mesh slices; erecting a model and pouring concrete. The construction method disclosed by the invention has the advantage that the purposes of shear resistance and strengthening of the concrete box beams are achieved by mounting longitudinal corrugated steel web components in box chambers of box beams, increasing the number of webs of the box beams and reducing the main tensile stress of original concrete webs of the box beams.
