hollow selfdrill grouted anchor
Hollow selfdrilll grouted anchor embodies drilling, grouting and anchoring as a whole. Widely used as an efficient anchoring means, in tunnel presupport, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sinkage.
It's irreplaceable in narrow construction environment.
consists of anchor rod, steel drill bit with alloy head, anchor coupling (optional), arch plate, grouting stopper and hex nut.
Product Structure:
1) Nut: The nut can delivery the surrounding rock stress to arch plate centralized
2) The arch plate can bear more stress of surrounding rock
3) Grouting pressure can be kept at a high level under the help of grouting stopper, so the cracks are fully filled and the fractured rock is improved
4) The anchor body with the continuous international standard wave-shape thread, convenient to fit drilling bit, coupling and bolt, also can cut arbitrary shape and connecting lengthening
5) The coupling can let the pipe shed drilling to the design depth when drilling and lengthening at same time.
6) With a bit at the anchor head, it is easy to cut through various rocks.
