Drilled hollow bar

Whether you are looking to construct or repair a commercial runway, apron, or taxiway with stringent ASFA specifications, or you are looking for a contractor that has the skill and expertise to meet the demands of the Department of Defense, Sinorock is your hollow bar supplier for civil construction of choice.
With high quality self drilling hollow anchor bar system ,Sinorock leading anchoring subjects have been exported to more than twenty countries and have been taken into use in a great many conditions like mines,tunnels,hydroelectric projects,civil constructions,transportations and other geological engineerings.
For mining applications, the Sinorock Drill Hollow Bar System is used as self drilling
rock bolt in areas of high stress at pillars, crossheads or abutments.
Other applications include the use of the self-drilling bar as an injection
conduit for resin, grout or water proofing agents.
Spiles provide a protective canopy, toenable the heading of a tunnel to be
advanced without the risk of falling debris. Often used with NATM
— New Austrian Tunneling Method —construction.
Sinorock Drill Hollow Bar System Spiles enable drilled installation, reducing
localised disruption and providinga conduit for grouting. Subsequent grouting assists in the consolidation of the surrounding ground.
Corrosion protection for the hollow grouted bars can be accomplished via any desired methods currently used. The force transmitting drill bit can be made of stainless steel, which can handle any compressive force that is place on it. The hollow soil nail bar is the only component of the system that experiences the tensile forces placed upon the system, which can also be made of stainless steel.

Hollow bar for highway

For now, this highway is a bright spot for tourism, because it combines project with natural scenery. Of course, it is convenient for people’ life and will bring benefit to local people.But there are plenty of mountains and rivers in China, So highway must cross this area.
While based on complex geological conditions, the security and supporting effect are more important, so hollow bar system is quite necessary.

With the development of sedimentation, the amount of sediment is increasing and the volume turns bigger, which will bring difficulties for project. So based on terrain condition and projects’ safety, self drilling hollow bar plays a quite important role.
Self drilling hollow bar can not only make construction more convenient and efficient, but also have effect for permanent supporting.
Self drilling hollow bar, as an efficient anchoring method, usually applies in weak and broken conditions. As for the projects with severe sediment accumulation, it has much more advantages:
1. Self drilling hollow bar combines drilling, grouting and anchoring together, it is high-quality, time-saving and easy to operate.
2. Self drilling hollow bar adopts special thread on its surface, so it can connect with other assorted machines smoothly.
3. Self drilling hollow bar can be cut according to your demand.
4. Self drilling hollow bar can be used for permanent support in weak conditions. It has enough pre-stress to control the deformation of project.
