<p>A construction method for indirectly heating recoverable anchors comprises the steps of laying an anchor body (1), whose external surface is bond with a cover (2) and inside which a cavity (3) is contained, in soil body or rock reinforcement (4), the cover (2)'s bond strength being lowered with temperature rising; and recovering the anchor body (1) through indirectly heating the anchor body (1) and the cover (2) bond on its external surface by the cavity (3), thereby lowering the bond strength between the cover (2) and the anchor body (1). The engineering cost can be reduced and the recovery rate of the anchor can be increased through the method. A cavity anchor and a high-pressure heater used in the construction method for indirectly heating recoverable anchors are provided at the same time.</p> |
