Abstract:
A construction method for a recyclable anchor rod. The recyclable anchor rod includes a reinforcing steel bar body and an unlocking device. The unlocking device includes a housing, a fixed panel, a top limiter, lifting screw limiters, a lifting screw, transmission gears, gear clamping arms, a thread limiter, and a pressure bearing plate. The construction method includes: 1, positioning; 2, drilling; 3, anchoring; 4, performing primary grouting; 5, performing secondary grouting; 6, tensioning and locking; and 7, recycling the reinforcing steel bar body. Shock-absorbing pressure-bearing devices are arranged between the lower end of the housing and the pressure bearing plate. The present disclosure effectively solves the problems that a conventional anchor rod hinders the construction of an adjacent underground structure and pollutes underground environment, and the problems that the existing recyclable anchor rod unlocking device is unstable, does not have earthquake resistance, and cannot realize 100% recovery of rod bodies.
