Abstract
The invention discloses a deformation anchor cable capable of increasing resistance continuously, which is characterized by comprising a friction sleeve, a contractible member and a first fixing inhaul cable. The inner diameter of the friction sleeve decreases from one end of the sleeve to the other end of the sleeve gradually. The contractible member is of a tubular structure and nested in the friction sleeve, the outer diameter of the contractible member decreases from one end of the member to the other end of the member gradually, and the outer wall of the contractible member is contacted with the inner wall of the friction sleeve. One end of the first fixing inhaul cable is connected with the contractible member, and the first fixing inhaul cable is led out from one side at the pipe orifice end with smaller inner diameter of the friction sleeve. When large deformation occurs on surrounding rocks, the deformation anchor cable can be tensioned to stretch without being damaged, increase working resistance continuously and absorb deformation energy of the surrounding rocks constantly in the process. Furthermore, the deformation anchor cable capable of increasing the resistance continuously has the advantages of being simple in structure, easy to process, convenient to operate and the like.
