Claim 3:
4. The construction method for a deformable anchor cable capable of being prestressed according to claim 3, wherein by reducing the thickness of the thick section of the rubber plug, the contact stiffness between the bottom end of the outer sleeve and the rock mass at the bottom end of the enlarged part of the anchor hole can be improved, thereby increasing a contact force F1 between the bottom end of the outer sleeve and the rock mass at the bottom end of the enlarged part of the anchor hole, and further reducing a tensile force F2 borne by the nut and the tray, and preventing the nut from being damaged, wherein the sum of F1 and F2 is the total bearing force of the anchor cable, and is also equal to the tensile force borne by the anchoring agent; and by increasing the thickness of the thick section of the rubber plug, the contact stiffness between the bottom end of the outer sleeve and the rock mass at the bottom end of the enlarged part of the anchor hole can be reduced, thereby reducing the contact force between the bottom end of the outer sleeve and the rock mass at the bottom end of the enlarged part of the anchor hole, preventing the rock mass at the bottom end of the enlarged part of the anchor hole from being damaged, and making the nut fully play own role.
