Down-the-hole drilling RIGS in urban subway tunnel construction

Notícias 83 Views
In urban metro tunnel construction, challenges like complex environments and limited space exist. Down-the-hole (DTH) drills are widely used in metro construction due to their unique advantages. Metro tunnels are typically built underground in cities, requiring drilling operations in tight spaces. down the hole drilling rig

 

DTH drills are small and lightweight, easy to move and operate on metro construction sites. They adopt low-noise designs to reduce impacts on surrounding residents and the environment. In rock section excavation of metro tunnels, DTH drills can drill 89-127mm diameter and 2-4m deep blast holes for blasting.

Additionally:

 

  1. Their efficient dust removal devices effectively control dust pollution, protecting workers’ health.
  2. The dust control also safeguards the urban environment during metro construction.
  3. The compact design and low noise make DTH drills suitable for urban metro projects with strict environmental requirements.down the hole drilling rig
