Self-drilling hollow bolts common application scenarios
by Anchor S. Web DesignerIn recent years, with the increasing
demand for rock and soil support, drilling equipment is also constantly updated
and developed, while the cost of labor and lease increases and the requirement
of construction, the period becomes higher and higher. In addition, the
self-drilling hollow bolt has an excellent anchoring effect under the geological
conditions of easy hole collapse, which makes the self-drilling hollow bolt
more and more widely used. The self-drilling hollow anchor is mainly used in
the following scenarios:
1. Use as a pre-stressed anchor: instead
of anchor cable, self-drilling hollow anchor rod is drilled to the required
depth, then end grouting is carried out, and tensile force is applied after
solidification.
2. Used as micro-pile: self-drilling
hollow anchor rod can be drilled down to form micro-pile, which is often used
in wind power station Tower Foundation, Transmission Tower Foundation, building
foundation, retaining Wall Pile Foundation, Bridge Pile Foundation, etc.
3. Used for soil nailing: commonly used in slope support, instead of the conventional reinforced anchor, can also be used for deep excavation slope support.
4. For rock pitons: in some rock slopes
or tunnels where the surface is weathered or the joints are seriously
developed, the rock blocks can be bonded together by grouting after drilling
with self-drilling hollow anchor rods to improve their stability, such as easy
to collapse the road, the railway rock slope reinforcement, in the loose tunnel the mouth can also replace the conventional pipe shed for reinforcement.
5. Strengthening infrastructure or
disaster management. With the increase of the supporting time of the original
rock and soil supporting system, some problems may appear in these supporting
structures, which need to be reinforced or treated, such as the deformation of
the original slope, the settlement of the original foundation, the uplift of
the roadway surface, etc., the self-drilling hollow bolt can be used to drill
into the ground of the original slope, foundation, or roadway for grouting and
consolidation of cracks to prevent geological disasters.
Sinorock is a high-tech enterprise
specializing in the R & D, manufacturing, and sales of self-drilling hollow
anchors and related equipment. SINROCK has served more than 50 countries on six
continents over the past 19 years, Sinorock self-drilling anchor has been
widely used in railway engineering, Highway Engineering, Water Conservancy, and
hydropower, Subway, coal mine tunnel, slope support, and so on.
