Summary:The invention discloses a recoverable pre-stressed anchor cable and a construction method thereof. The recoverable pre-stressed anchor cable is characterized in that an anchoring section is connected with a free section through a connector, a high-temperature device is installed in the connector in a matching mode, and the high-temperature device is contiguously connected with an anchoring part. The construction method includes the following steps: firstly conducting assembling an anchor cable; sending the anchor cable into an anchor drill hole in the slope surface; conducting grouting through a drilled grout hole; conducting tension processing to the free section; conducting hole sealing to the anchor drill hole in the slope surface; after the anchor cable is used, softening the anchoring section in the connector through the high-temperature device, and the anchoring section is enabled to break away from the connector; applying a drawing force on the free section, and pulling out the free section from the an
