Rotary spraying anchor rope drill body and construction process of rotary spraying anchor rope
The invention belongs to the field of building construction, is suitable for the technical field of rotary spraying anchor cable construction and provides a rotary spraying anchor rope drill body and a construction process of a rotary spraying anchor rope. The rotary spraying anchor rope drill body comprises a double-pipe rotary spraying drill rod, a diameter-variable linkage clamping groove drill rod, an anchor head and a bottom sealing steel ball, the front end of the double-pipe rotary spraying drill rod is connected with the front end of the diameter-variable linkage clamping groove drill rod, the rear end of the diameter-variable linkage clamping groove drill rod is connected with the anchor head, and the bottom sealing steel ball is positioned at a joint of the double-pipe rotary spraying drill rod and the diameter-variable linkage clamping groove drill rod. The construction process includes 1), making a steel stranded wire; 2), machining an anchoring body; 3), drilling to form a hole; 4), feeding the steel stranded wire; 5), inputting the bottom sealing steel ball; 6), expanding the hole through rotary spraying; 7), tensioning and locking the anchor rope. The rotary spraying anchor rope drill body is convenient to use and high in construction efficiency; by the construction process, drilling speed can be increased effectively, process steps can be simplified, disturbance to the surrounding can be reduced, and nearby buildings and structures can be protected effectively.
