Abstract:
A self-drainage anchor cable system is provided, wherein a drainage section ( 15 ) is arranged above the internal anchoring section ( 14 ) of an anchor cable; a first end of the steel strand ( 2 ) extends into a bottom of the borehole ( 1 ); the isolation pipe ( 3 ) is sleeved on the steel strand ( 2 ) in the drainage section ( 15 ), and the permeable pipe ( 4 ) is sleeved on the isolation pipe ( 3 ); a length of the isolation pipe ( 3 ) is larger than a length of the permeable pipe ( 4 ), and there is a space ( 5 ) between the isolation pipe ( 3 ) and the permeable pipe ( 4 ); the water stop rings made of water-expanding rubber ( 6 ) are provided at both ends of the isolation pipe ( 3 ), and end portions of the permeable pipe ( 4 ) are in contact with the water-expending rubber water stop rings ( 6 ) A construction method for the self-drainage anchor cable system is also provided.

Claim (Index 1):
A self-drainage anchor cable system for slope protection, comprising: a borehole, a steel strand, an isolation pipe, a permeable pipe, water stop rings made of water-expanding rubber, a drain pipe, a protection pipe, cement mortar and external anchor head, wherein the borehole is drilled on a slope; a depth of the borehole ensures an internal anchoring section is below a potential sliding surface; a drainage section is arranged above the internal anchoring section of an anchor cable; a first end of the steel strand extends into a bottom of the borehole, and a second end of the steel strand is connected to the external anchor head; the isolation pipe is sleeved on the steel strand in the drainage section, and the permeable pipe is sleeved on the isolation pipe; a length of the isolation pipe is larger than a length of the permeable pipe, and there is a space between the isolation pipe and the permeable pipe; the water stop rings made of the water-expanding rubber are provided at both ends of the isolation pipe, and end portions of the permeable pipe are in contact with the water-expending rubber water stop rings; holes are drilled on the water stop rings made of the water-expanding rubber; a water inlet of the drain pipe passes through the holes of the water stop rings made of the water-expanding rubber and extends into the space between the permeable pipe and the isolation pipe, so as to reach a bottom of the drainage section; a water outlet of the drain pipe is placed in a safe zone which is below the slope, and an elevation of the safe zone is below the bottom of the borehole; a section of the drain pipe, which is buried in the slope, is covered with the protective pipe; the borehole is filled with the cement mortar except for the space outside the isolation pipe at the drainage section.
