The anchor bolts can be simultaneously drilled, installed and grouted to create a secure bond in most ground conditions. Threaded eyebolts can then be attached to the tendon for quick and easy fixing of the rock netting.
The versatility, speed and performance of Sinorock self-drilling anchor piles is probably most evident in the breadth and diversity of structural stabilisation applications for which they can be used.
From strengthening marine quay walls to reinforcing railway bridges and underpinning house foundations, the Sinorock solution delivers a host of benefits that can simplify apparently complex projects and make the difference in feasibility.
For fixing, a wide range of options is available, from a cementitious based grout through to specialist resins and mechanical fixings.
With our own qualified geotechnical engineers,Sinorock can offer the full solution to bolting, from design to installation and testing to BS8081.
Often, a anchor bolt will be made up from hollow drill steels and sacrificial drilling bits. During drilling, grout is pumped through the centre of the drill steel and flushes any debris from the hole. Once at its required length, the drill string is cut and becomes the anchor.
This is particularly ideal for poor ground conditions where ‘open-hole’ drilling is unlikely to succeed.
