Abstract
A method for attaching an anchor to an end of a tensile member by inverting the assembly of anchor and tensile member and injecting pressurized potting compound. A length of filaments of the tensile member are placed within a cavity through the anchor. The anchor and filaments are placed in an inverted position, with the distal end of the anchor facing downward and the cable extending upward out of the anchor. If the anchor has an open distal end this is sealed. Liquid potting compound is injected into the anchor cavity and allowed to solidify. During the solidification process, a controlled translation (pulling) of the cable is preferably introduced.
Claims20
A method for adding a termination to an end of a tensile strength member including multiple synthetic filaments, comprising:
- (a) providing an anchor with a proximal end, a distal end, and a cavity;
- (b) said cavity including a distal region and a neck region;
- (c) providing a potting compound in a liquid state, said potting compound being configured to transition to a solid state over time;
- (d) placing a length of said filaments within said cavity;
- (e) placing said anchor and said length of filaments in an inverted position whereby said proximal end of said anchor lies above said distal end of said anchor, with said tensile strength member extending upward out of said proximal end;
- (f) sealing said distal region of said cavity;
- (g) injecting said potting compound in said liquid state into said distal region of said cavity;
- (h) applying a vacuum to said cavity;
- and
- (i) maintaining said anchor and said length of filaments in said inverted position until said liquid potting compound has transitioned substantially to a solid.
