In coal mining, tunnel support is a crucial aspect of ensuring safe production. The anchor rods play an important role in this field:
Tunnel Reinforcement: Anchor rods, as the basic components of tunnel support, reinforce the surrounding rock of the tunnel, enhancing its safety and stability.
Mine Safety: Anchor rods are not only used in coal mines but also widely applied in other mines to ensure safety during mining operations.
Engineering Technical Reinforcement: Anchor rods are also used for the main reinforcement of slopes, tunnels, dams, and other engineering structures, improving the overall stability and durability of these structures.

In concrete pouring for cast-in-place piles, the acoustic testing pipes are key components for ensuring pile quality:
Ultrasonic Testing Channel: Acoustic testing pipes provide a channel for ultrasonic probes to be placed normally at the bottom of the pile, ensuring smooth progress of ultrasonic transmission testing of the pile.
Pile Quality Assessment: Ultrasonic testing conducted through acoustic testing pipes can accurately assess the quality and integrity of piles, providing strong support for engineering quality control.
Construction Efficiency Improvement: The use of acoustic testing pipes also improves the efficiency of concrete pouring for cast-in-place piles, ensuring smooth progress of the construction process.
