Using method for foaming self-breaking-type cement mortar in anchor rod or anchor cable anchorage section

The invention discloses a using method for foaming self-breaking-type cement mortar in an anchor rod or anchor cable anchorage section. The using method comprises the following steps: through pouringthe foaming self-breaking-type cement mortar added with a vulcanizing agent, portland cement, fine aggregate, rubber powder, a foaming agent, paraffin, a microwave absorbent, a reinforcing agent, a filling agent, a modification flowable agent and a dispersing agent into the periphery of the anchor rod or anchor cable anchorage section, forming an anchoring body; while an anchor rod or an anchor cable is detached, applying a microwave field into the anchoring body, rapidly rising an internal temperature of the cement mortar, promoting the foaming agent to foam and deflate, and expanding a volume of the fine aggregate, thereby enabling the cement mortar to be expanded and cracked, and self-breaking. Because strength of the cement mortar is greatly reduced after breaking, an anchor rod or anchor cable support structu
