Self-drilling anchor hollow rod R thread is mainly used for engineering reinforcement in the following areas:
1. Tunnels and underground projects
Roof support: In tunnel construction, self-drilling anchors are used to support the tunnel roof to prevent the collapse of rock or soil layers.
Wall reinforcement: Used to reinforce tunnel walls and enhance structural stability.
2. Mining
Tunnel support: In mine tunnels, self-drilling anchors are used to support tunnels to prevent surrounding rock collapse and ensure construction safety.
Mine pillar reinforcement: By anchoring the mine pillars, the overall stability of the ore body is enhanced and the service life of the mine is extended.
3. Foundation reinforcement
Slope stability: Self-drilling anchors are used to reinforce slopes to prevent landslides or soil collapse.
Foundation support: When building on a weak foundation, it is used to enhance the bearing capacity of the foundation and prevent the building from settling or tilting.
4. Foundation pit support
When excavating deep foundation pits, self-drilling anchor bolts are used to support the foundation pit slopes to prevent collapse or soil displacement.
5. Emergency rescue in civil engineering
Preventing landslides: In natural disasters such as landslide areas after heavy rains, self-drilling anchor bolts can be used to quickly reinforce landslide bodies to prevent secondary disasters.
Dam reinforcement: Used for emergency reinforcement of dams to enhance the flood resistance of dams.
The R thread design of the self-drilling anchor bolt enables it to be used in high-stress, high-friction environments, providing reliable connectivity and support, and is particularly suitable for complex geological conditions and engineering environments.
