R32 Q235 Steel Hollow Grouting Self Drilling Anchor Bolt For Slope Stabilization

Product Description:

Minetech self-drilling hollow grouting anchor is comprised of a hollow bar, a drill bit, a coupler, a centralizer, a plate and a nut. It is a new type of bolt which can perform drilling, grouting and anchoring in a single operation.
The hollow anchor bar of self-drilling hollow grouting anchor is fully threaded, that can be cut to any length or extended according to the needs of the project. Grouting through the hollow bar can improve the grouting compactness, thereby improving the bond stress to the rock and also improving the durability of the bolt. Self-drilling hollow grouting anchor is especially suitable for weak, broken and other difficult formations.

Features:

1. It can solve defects that unfilled grouting of traditional mortar anchor bolt during the construction and can’t grouting with pressure.
2. The operation is simple, cost is low, construction is convenient and efficiency is clear.
3. It can realize grouting with pressure and reform foundation surrounding rock conditions.

Technical Parameters:

Applications:

Self drilling anchor 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.

Packing and Shipping:

Packed in Carton or Wooden Box.

Sample will be sent by Fedex, shipping time 7-10days, main order will be shipped by sea.
