Title:
WATER JET TECHNOLOGY-BASED ANCHOR CABLE SELF-DRILLING AND RAPID ANCHORING CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/228004
Kind Code:
A1
Abstract:
A water jet technology-based anchor cable self-drilling and rapid anchoring construction method, comprising the following steps: adjusting an angle-adjustable drilling mechanism so that a hollow anchor cable (1) faces a preset drilling direction; connecting a water jet generation device to the rear end of the hollow anchor cable (1); starting the water jet generation device and the angle-adjustable drilling mechanism to perform a drilling operation; after the drilling operation is completed, coaxially connecting a rigid pipe (4) to the rear end of the hollow anchor cable (1), and mounting the rigid pipe (4) onto the angle-adjustable drilling mechanism; connecting a discharge port of an anchoring agent feeding device to the rear end of the rigid pipe (4); and starting the anchoring agent feeding device and the angle-adjustable drilling mechanism to perform an anchoring operation on the hollow anchor cable (1) in a drilled hole.
