Product DescriptionThe product is composed by hollow anchor bar,
anchor nut, anchor plate, anchor coupler, drill bit, and the hollow
anchor bars can be cut and lengthened by coupling on
request. Self drilling anchoring system is an advanced
system which can ensure the anchoring effect for complex ground
conditions. It can be integrated with the functions of drilling,
grouting and anchoring. It can be used in railway
system, metro project and infrastructure . As an efficient
anchoring method, it's also widely used for pre-support, radial
support, slope stabilization, foundation support , soil nail,
retaining wall, etc.Features1. Safe, reliable, and time
saving. Self drilling system eliminates the requirement for a
cased borehole. 2. Simple installation & operation. 3. Choice of
drill bits for different ground conditions. 4. Grouting works
synchronize with drilling or after drilling. Grout can fill
fractures effectively. 5. Anchor bars can be cut and
lengthened on request, applying to narrow spaces. 6. It provides
higher bonding stress than smooth steel pipe depending on
continuous wave thread. ApplicationRailway System Metro Project
