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.

The science behind FRP trough covers is a testament to human ingenuity. These covers are fabricated using a sophisticated process that involves laminating layers of fiberglass with a specially formulated resin. This combination results in an exceptionally durable and lightweight material that can withstand harsh environmental conditions, including extreme temperatures, corrosive chemicals, and physical impacts. Moreover, the inherent properties of FRP offer unparalleled resistance to UV radiation, ensuring that these trough covers maintain their structural integrity and appearance over decades of service.
