"Warner card" type anchor detector uses and characteristics of MT-II bolt detector (Patent No: ZL 90 9 6102996.X) is the national "eight five" key scientific and technological project "Construction quality shotcrete support detection technology "One of the sub-project, which is shotcrete support engineering quality inspection to detect the position of a metal bolt intelligent instrument, in June 1995 through the identification of the former Ministry of Coal Industry Science and Education Division organized. Senior Chief Engineer for the patent technology (design) people. Use "Warner card" anchor detector can quickly find the anchor spray shotcrete layer and under the roadway network in the metal bolt anchor position, which can be arranged to determine the quality of the bolt, and easy to find anchor anchored chisel force test, shotcrete support for quality evaluation of roadway to provide evidence. "Warner card" anchor detectors are intrinsically safe, can be used to have gas and coal dust explosion hazard. "Warner card" Bolt detector technical parameters 1 Scope: can be used without Bolt detector price of steel mesh, steel mesh can also be used to pave the roadway two depths: 400mm (ring finger probe to bolt tray distance) 3 Positioning accuracy: 1cm (refer to the instrument as determined by the distance between the location of the actual metal metal edges) 4 Power: Nickel-cadmium rechargeable batteries, with a dedicated charger charging. A charge can be used continuously for eight hours 5 Shape and size: ABS plastic anchor quality detector, base length 0.9m (later extended up to 2.7m), the weight of 2kg. Bolt detector important role: In the bolting of hollow grouting anchor pullout test: test construction quality bolt, one anchor pullout method for the determination. Before bolt shotcrete not covered by Warner brand ZY-300 type bolt tension meter or MC / TG ??series torsional torque wrench directly measured. After the clamp bolt, slow uniform pressure gauges pull up anchor and design value reaches a value corresponding to date, or to anchor loose far, generally do not do destructive testing. After the bolt is covered with shotcrete and steel mesh is large, general metal detection equipment can not be accurately ascertain the exact location of anchor bolt Hebei detector, Warner brand new bolt detector can effectively solve this problem anchor probe Miriam, after the hollow grouting anchor bolt detector with proven, the mine carved bolt for bolt tension meter measured before connecting part. Bolt detected by the number of 30-50 meters per long cavern or every 300 samples with a bolt groups of not less than three, mine should be evenly anchor bolts in a row selected checkpoints within the same section .
