A pre-stressed anchor cable and a pre-stressed anchor cable one-time forming construction method
The invention provides a pre-stressed anchor cable and a pre-stressed anchor cable one-time forming construction method. The method comprises the steps of: 1) providing an anchor cable and a rotary jet grouting drilling machine comprising a hollow drill stem provided with a drill bit at the front end; 2) installing the anchor cable in the hollow drill stem; 3) using the rotary jet grouting drilling machine to perform rotary jet grouting drilling in soil layers to form an anchor cable hole, the anchor cable entering the anchor cable hole along the hollow drill stem; 4) pulling the hollow drill stem out from the anchor cable hole after the drilling of the rotary jet grouting drilling machine reaches a target depth; 5) performing grouting in the anchor cable hole; 6) stretching and drawing and locking the anchor cable. The pre-stressed anchor cable one-time forming construction method enables the drilling, the anchor cable installing and the grouting to be performed simultaneously. The pre-stressed anchor cable one-time forming construction technology prevents the problem of hole collapse caused by anchor cable installation after drilling, and reduces construction steps and saves time.
