Self-Drilling Anchor is a unique anchoring system and is today's
Answer to the increasing demands of the tunnelling industry and
ground engineering for safer and faster production.
The system provides advantages for all areas of its applications,
where boreholes would require the
Time consuming drilling with casing systems in unconsolidated or
cohesive soil.
Applications
It is usually applied in complex layer formation of broken rock,
loosen soil, weathering rock where is difficult to make holes. It
is good for supporting and improving surrounding rock, and can
achieve good supporting effect in tunnel support, radial support
and various types of slope treatment projects.
Features
1. Simple operation, easy to use, ensure that applying prestress
could be
conducted.
2. Through the hollow rod to achieve high-pressure grouting, rock
reinforcement to improve project quality
reinforcement to improve project quality
3. Avoid the mortar loss when the traditional grouting tube pulled
out.
4. Center is good, mortar can wrap the bolt body together, so that
it can avoid corrosion to achieve a long-term supporting purpose.
The Structure: alloy rod, grouting stopper, plate, nut and anchor
head components.
Accessories: Fish Hooks, Barrel, wedge, Grouting tube, Breathing tube, Bearing plate.
