The invention provides an anchor-cable-pore-forming two-stage sleeve construction method. The anchor-cable-pore-forming two-stage sleeve construction method includes the following steps that a large-diameter first sleeve is subjected to pipe-following drilling to the maximum pore depth through a large-diameter eccentric drilling device; the large-diameter eccentric drilling device is taken out, asmall-diameter eccentric drilling device is replaced, a small-diameter second sleeve is subjected to pipe-following drilling through a small-diameter eccentric drilling device, and the depth reaches the preset depth or the maximum follow-up pore depth; anchor-cable pore forming under the complicated geological condition is achieved through the steps. By means of the construction method of two-stage sleeves capable of mutually sleeving, smooth pore forming under the complicated geological condition can be achieved, pore-forming time is 3 days to 4 days, and compared with the construction periodof 49.5 days in the prior art, the construction period of the method is greatly shortened; the pore-forming cost of each pore is also greatly reduced.
