Self Drilling Anchor Bolt

Overview:
Self drilling anchor bolt can be used for permanent support and advance support in complex ground conditions. The pressure grouting of the bolt through the hollow rod can achieve the purpose of solidification crushing rock mass, separating the underground water and the anti-corrosion of the rod body, it can quickly form support force and control the stability of surrounding rock. Hollow bolt of the anchor body adopts hollow design, taking the rod hole as drilling grouting channel, compared with the solid rod, the hollow rod design can get better stiffness and shear strength.
Application:
Applicable to railway, highway, tunnel, mine, water conservancy hub, dam, bridge foundation, high-rise building foundation and building reinforcement and other projects.


Feature:

  • Hollow design, to achieve grouting function.
  • Drilling and grouting can be done simultaneously. With good grouting spread radius and reliable anchoring quality, fractures can be filled effectively.
  • The anchor bar with standard full thread can be cut according to your requirement. The cut anchor bar can be connected by couplers. It’s suitable in narrow work space.


Executive Standard:
