Anchor end device of tension-compression pre-stressed anchor cable
The invention discloses an anchor end device of a tension-compression pre-stressed anchor cable. The anchor end device of the tension-compression pre-stressed anchor cable mainly comprises an expansion shell inside wedge, an expansion piece, an extrusion body, a circular tightening ring, an extrusion nut, an expanding sleeve and a welding circular ring, a through hole through which a steel strand passes and a grouting hole are formed in the middle of the expansion shell inside wedge, the steel strand at the upper end of the expansion shell inside wedge near the expanding sleeve is firmly connected with the expansion shell inside wedge, embedded holes in which extrusion bodies are embedded are uniformly distributed in the edge of the expansion shell inside wedge, the expansion piece closely surrounds the expansion shell inside wedge, the lower end is connected with the welding circular ring, the circular tightening ring for fixing the expansion piece is arranged at the middle of the expansion shell inside wedge, the expansion piece is provided with the extrusion nut near the lower part, and the extrusion nut is connected with the steel strand. According to the anchor end device of the tension-compression pre-stressed anchor cable, the stress distribution on the anchor end is more uniform and reasonable, the design intensity of the pre-stressed anchor cable is improved, and the break (crack) degree of the grouting at the part in contact with a supporting body is alleviated; the anchor end device of the tension-compression pre-stressed anchor cable can be broadly used for the long-term or temporary strengthening for side slopes, foundation ditches and the like.
