In addition to breaking through rocks, tunnel bench drilling bits also play a role in stabilizing tunnel walls. As tunnels are excavated, the surrounding soil can become loose and unstable, posing a danger to workers and the structural integrity of the tunnel. Tunnel bench drilling bits are used to create holes for support structures such as bolts and mesh, which help to secure the tunnel walls and prevent collapses. By stabilizing the tunnel walls, these drilling bits ensure the safety of workers and the success of the tunneling project.

Fiberglass steps are crafted through a meticulous process that involves layering fiberglass strands over a sturdy core, typically made from composite materials or metal. This construction method ensures that each step can bear significant weight without bending or breaking, making them exceptionally reliable for high-traffic areas. The surface of these steps is often textured to provide a non-slip grip, ensuring the safety of those who use them, even in wet or icy conditions.

  • Typically made from high-strength steel, the rock drill shank is hardened and tempered to endure extreme pressure and impact loads. The material selection and heat treatment processes ensure it can withstand the intense forces exerted during drilling, resisting deformation and fracture even under harsh conditions. Some advanced models may incorporate tungsten carbide inserts for enhanced wear resistance, extending the lifespan of the shank.
  • The core of fiberglass sewer pipe lies in its composite structure, which consists of a strong, flexible glass fiber matrix encased in a tough, waterproof resin. This combination provides the pipe with outstanding strength-to-weight ratio, making it easier to handle and install compared to heavy concrete pipes. Additionally, the corrosion-resistant nature of fiberglass eliminates the common issues associated with metal pipes, such as rust and corrosion, ensuring a longer lifespan for the sewer system.
