description The invention relates to a construction method for removing anchor rods, in particular to a construction method for removing anchor rod obstacles in a grooving process of an underground diaphragm wall. By means of the construction method, the technical problems that in the prior art, the anchor rods are removed directly through a grooving machine by the adoption of conventional steel pipes, groove wall collapse accidents are caused easily, and the safety of surrounding buildings and structures is influenced can be solved. The construction method comprises the steps of conducting construction preparation, placing a drilling machine in place, conducting drilling, spreading a drilling rod, manufacturing grout, conducting grouting operation, moving a machine, conducting secondary grouting, conducting maintenance to designed strength, conducting cutting through grooving machine and conducting acceptance check.
