Product Description

Self drilling hollow bar anchor is a bolting solution for unstable ground conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations.
self drilling hollow bar anchor consists of anchor nut, anchor plate, anchor coupler, hollow anchor bar, sacrificial drill bit

Self-drilling hollow bar anchors are successfully used for anchoring in poor ground, cohesive and non-cohesive soils, and in case of unstable boreholes. Main applications are:
l Road/rail construction and maintenance
Tunneling & Mining
    1, rock bolting 2, face anchoring 3, forepiling 4, foot piles 5, tunnel portals, treanches, and cut and cover areals
Rural environments
Private residences
Special foundations
Avalanche protection structures

System description
1, hollow core with continuous hot-rolled outside thread
2, application as injection anchor without casing, especially for non-stable boreholes
3, self-drilling installation, utilization of the anchor bar as drill rod with a single-use drill bit
4, easy extension of the anchor bars by anchor coupler
5, grouting or development of the grout body either simultaneously with drilling using a rotary injection adapter or afterwards
6, assembly of the anchor head with the anchor plate and the nut, stressing and locking

Prime advantage of the self-drilling hollow bar anchor
1, easy and similar operation principle for different rock mass and soil conditions
2, drilling, anchoring and grouting can be performed in one single operation
3, no pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installation necessary
4, minor space requirement for the accomplishment of anchoring
5, optimized machinery and manpower requirements
6, basic dimensioning of the required anchoring forces by choosing the appropriate anchor type
7, optimum bonding of the profiled anchor rod and the grout
8, adjustment of the drill bit design and diameter to different rock mass and ground conditions
9, simple anti-corrosion method available
*0, appropriate for temporary or permanent applications
