Slumping hole seriously and need to be especially long anchor rod and the narrow narrow section of work conditions, the ordinary can anchor rod are often not to force.Z Y since by-step slurry injection anchor rod will drill holes, note thick liquid and solid work, such as anchor to a body, in the tunnel before super protection, diameter to the buried and each kind of side slope protection, back fill soft soil foundation in reason, high ground force changed shape should be the cure of disease to harm engineering could very well change in the surrounding rock, and to manage to protect effect. | |||||||||||||||||||||||||||||||||||||||||||||||||

Enter type slurry injection anchor rod structure Z Y since no seam mining with good good thick wall steel pipe materials, table surface for international, often with the wave shape screw lines of empty heart anchor rod as the main body, and combined with the drill head, with a horse, which have good good drill |

Z series since by-step slurry injection anchor rod should be extensively used in public, iron road, tunnel water conservancy water and electricity engineering, ground before the pipe cavity under the tabernacle, guard, side slope protection, suitable scope of use should be use in soft and weak surrounding rocks, broken broken broken belt, highland should force changed shape and complex mixed soil quality, and the article, don't is slumping hole seriously and long anchor rod applied to workers and narrow narrow segment of industry engineering, is to improve the engineering stability in question one of the most economic effect of the method. We mentioned In each kind of engineering at that deposited in the soft and weak surrounding rocks, broken broken broken belt, high ground |
