Sinodrills SDAS Self Drilling Anchor System

Application:

Self drilling anchor bolt system is mainly used in slope

stabilization, tunneling pre-support, foundations with micropiles,

it is also widely used in the railway system, metro project etc. It

can be installed in sites with weak rocks, loose soil, weathered

layer, sand with stone layer and so difficult to create a hole in

complex formations. The unconsolidated ground condition favor

the self-drilling anchor bolt technique for fast and simple

method of installation compared to the traditional method.

Features:

1, Self drilling anchor system has two performances: the one is

drilling, the other one is grouting. It features a hollow bore for

flushing, or simultaneous drilling and grouting.

2, Self drilling anchor system is reliable, efficient and

convenient, which makes high piling output possible.

3, We can make the Hot-Dip Galvanizing Corrosion Protection

according to EN ISO1461
