Shanxi self into the hollow grouting anchor

Hao Bo Machinery specializes in the self-advancing hollow grouting anchor sales, for many years, large-scale, good reputation, is your first choice to purchase self-advancing hollow grouting anchor! Details of consultation 13,165,376,735 divided up shell hollow grouting anchor advancer type two from here to tell you about self-advanced grouting anchor. It also played a supporting role, the difference is its own bit, the job can be punctured. In the process of saving the link, higher efficiency. The disadvantage is that a rod to use a drill, drill bit can not be used more than once, will stay inside the bore, higher cost. Detailed self-propelled anchor structure: alloy drill: made from high quality alloy produced by precision processing technology from, with strong hardness and toughness, penetration can penetrate into the many types of wall rock anchor bolt body: assembly of The most important member, plays a major role in the drilling and anchoring. Connected sets: the connecting bolt for an extension in time. Plate: can withstand greater stress surrounding rock. Nuts: rock stress can concentrate on the plate. The main technical performance parameters: Model LZ25 LZ27 LZ28 LZ32 LZ38 LZ51 outer diameter (mm) ￠ 25 ￠ 27 ￠ 28 ￠ 32 ￠ 38 ￠ 51 Tensile strength (MPa) ≥650 ≥650 ≥650 ≥650 ≥650 ≥650 tooth height ( mm) 1.5 ± 0.1 Pitch (mm) 12.7 ± 0.1 L standard thread direction length 2.0 3.0 3.5 4.0 4.5 56 (can be customized according to needs) length tolerance ± 1% maximum drilling depth of 12 m. Remark tensile strength and length can be According to customer design requirements make self-feeding type bolt construction process 1, the alloy drill and anchor at one end and the other end connected to the solder sleeve, shank and then connect with the trolley or hand-held drill well. Press start drilling depth design shall raise the cooling water when drilling. (For a longer bolt, connected sets available to connect, and then drilling) 2. Remove the rig, the occluding plug set into the rod, and insert it into the hole, ready grouting. The special circumstances surrounding rock grouting pressure is too large or too broken, can be plugged anchoring agent. 3. The rapid grouting joints and bolt rear end connected to the other end of the joint grouting grouting machine connection. 4. start off grouting grouting grouting to be full and the pressure to meet the design value. Grouting pressure grouting machine depending on design parameters and performance is determined, sand lime than the reference value of 1: 0 to 1: 1, the water-cement ratio reference value of 0.45 to 0.5: 1.
