Self-drilling hollow anchor
rods have excellent anchoring effects when used in geological conditions that
are easy to collapse. Therefore, the application of self-drilling hollow anchor
rods is becoming more and more extensive. What scenarios can be used for
self-drilling hollow bolts? Let’s understand together:
1. Used as pre-stressed anchor
rod: used in slope, underground excavation, anti-floating, and other scenes
instead of anchor cables, self-drilling hollow anchor rods are drilled to the
required depth, and then end grouting is performed, and the tension is provided
after solidification pull;
2. Used as a micro-pile:
self-drilling hollow anchor rods can be drilled down and grouted to form
micro-piles, which are often used for wind power station tower foundations,
power transmission tower foundations, building foundations, retaining wall pile
foundations, bridge pile foundations, etc. ;
3. Used for soil nailing:
often used for slope support, instead of conventional steel anchor rods, and
can also be used for deep foundation pit steep slope support;
4. Used for rock nails: in
some rocky slopes or tunnels with severe surface weathering or joint
development, self-drilling hollow bolts can be used for grouting after drilling
to bond the rock blocks together and improve their stability, For example, the
rock slope reinforcement of roads and railways that are easy to collapse can
also replace conventional pipe roofs for reinforcement at the loose tunnel
entrance;
5. Foundation reinforcement or
disaster management. As the support time of the original rock-soil support
system increases, these support structures may have some problems that require
reinforcement or treatment, 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 original slope,
foundation or roadway ground, etc., for grouting and consolidation of cracks to
prevent the occurrence of geological disasters.
