Method for grouting and anchoring by adopting double-hole stop-grouting plug

The invention discloses a method for grouting and anchoring by adopting a double-hole stop-grouting plug. The method comprises the following steps: respectively inserting an anchor cable and a grouting pipe into an anchor cable insertion hole and a grouting pipe insertion hole; tightly binding the grouting pipe and the anchor cable together by using a flame-retardant adhesive tape; horizontally inserting the assembled anchor cable, the grouting pipe and the double-hole stop-grouting plug into the drill hole, and anchoring the anchoring end of the anchor cable into the drill hole by using an anchoring agent; firstly, the reserved end of the grouting pipe is connected with a grouting pipeline of a hydraulic pump, then non-shrinkage micro-expansive cement powder is added into the hydraulic pump to prepare slurry, then the hydraulic pump is started, and the slurry in the hydraulic pump is pumped into the drill hole; after grouting is completed, an iron wire is used for binding the end of the grouting pipe, and un
