  Hollow grouting bolt support is a key method of geological engineering structure reinforcement, because of its safety, high efficiency, low cost and other advantages, it has been used more and more in the scope of international geological engineering.

Talking about the Practical Function of Hollow Grouting Bolt Support

  The use of hollow grouting bolt support in published engineering projects has been rapidly carried out abroad. The meaning of hollow grouting anchor rod Hollow grouting anchor rod is a kind of prefabricated component in tension that is laid in soft rock. It is a rod-shaped prefabricated component made of metal materials or other modifier tension materials. It has gone through some mechanical equipment installation or bonding materials separated from the soft rock.

  Hollow grouting bolt support as a kind of tunnel support wrist has great advantages in terms of technical and economic development, and it can meet the characteristics of different geological standards. According to this advantage, the hollow grouting bolt is announced It has been widely used in engineering projects and proceeded rapidly. The hollow grouting anchor rod used in the announced project is generally composed of three root parts: anchor solid (or inner anchor head), hollow grouting anchor rod and cushion block.

Talking about the Practical Function of Hollow Grouting Bolt Support

  The spacer is the butt joint part of the bolt support structure and the hollow grouting bolt. It can reasonably modify the bearing capacity of the hollow grouting bolt, so that the load dissemination of the hollow grouting bolt is the average value, and the development of the hollow grouting bolt The actual effect of bolt support.

  In addition, the hollow grouting bolt and the preliminary bolt support can be connected into a whole, which is beneficial to bear the working pressure of soft rock. The hollow grouting bolt is located on the axis of the anchor cable installation. Its function is to transmit the tensile force from the cushion block to the anchor solid, so that the deformation of the soft rock of the tube bundle and the development of confining pressure are very important for manipulating the deformation of the soft rock. effect.
