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 6):
A construction method for a self-drainage anchor cable system, comprising steps of:\n (1) through slope engineering geological condition investigation, analyzing a location of a potential sliding surface, a depth of a groundwater level of a slope and a groundwater level line to be controlled; and drilling a borehole at an appropriate position of the slope to enter a location below the potential sliding surface and the groundwater level line; (2) determining a diameter and a quantity of steel strands according to an anchoring force required by an anchor cable; (3) modifying a length of a permeable pipe to equal a length of a drainage section, and modifying a length of an isolation pipe to be larger than the length of the drainage section; sleeving both ends of the isolation pipe with water stop rings made of water-expanding rubber, and sleeving the isolation pipe with the permeable pipe, wherein end portions of the permeable pipe are in contact with the water-expending rubber water stop rings; (4) manufacturing an anchor cable body, and installing the isolation pipe together with the permeable pipe and the water stop rings made of the water-expanding rubber into the drainage section above an internal anchoring section; (5) sleeving the drain pipe with a protection pipe, in such a manner that the drain pipe passes through holes of the water stop rings made of the water-expanding rubber and extends into a space between the permeable pipe and the isolation pipe, and a water inlet of the drain pipe is at a bottom of the drainage section; (6) after the water stop rings made of the water-expanding rubber are fully expanded with water, filling the borehole with cement mortar, and performing anchor cable tensioning and locking pre-stress; and (7) when a water head height of the water inlet of the drain pipe is greater than an elevation of the borehole, discharging groundwater by the drain pipe under a water head difference, which starts a siphon drainage process and generates a negative pressure in the space of the drainage section, in such a manner that the groundwater in the slope accelerates into the drainage section; after draining the groundwater of the slope, in-taking air through the water inlet of the drain pipe, in such a manner that suction and discharge of the drain pipe disappears, and an entire drainage process ends; wherein with cycles of rainfall infiltration, the drainage process circulates.
