Combined expanding head and rock-soil body composite anchor cable
The invention disclose a combined expanding head and rock-soil body composite anchor cable which consists of a plurality of anchor cable monomers arranged in rock-soil layer drilling holes in parallel, wherein cavities formed by springing blasting are formed at the tail ends of the rock-soil layer drilling holes; the anchor cable monomers are provided with steel strands and expanding heads; the expanding heads are ellipsoids; one end of each steel strand is fixedly connected with one end close to a long axis of the corresponding expanding head into a whole; the expanding head of each anchor cable monomer is placed in the cavity at the tail end of the corresponding the rock-soil layer drilling hole; outlets of the rock-soil layer drilling holes are covered with a plugging plate; and the other ends of the steel strands connected with the expanding heads penetrate through the outer side of the plugging plate. The composite anchor cable has the characteristics that a utilization rate of the steel strands of the composite anchor cable is high; the stability is good; the durability and the anchoring strength are high; and the mounting effect can be ensured easily.
