Lowari Tunnel Construction Brings Opportunities And Challenges
by Anchor S. Web Designer
Lowari Tunnel spans 8.75km from the Khyber-Pakhtunkhwa province of Pakistan to Dir and Chitral Valley and serves as a corridor link to the Asian countries through the Pakistan-Afghanistan-Tajikistan route, linking Chitral to the rest of the country.
The tunnel essentially allows traffic on the N45 National Highway to bypass the Lowari Pass and was intended to reduce the 14-hour drive between Chitral and Peshawar to only 7 hours. Scope of the project includes the construction of two tunnels (8.5 km and 1.9 Km), access roads and 12 bridges (35 km)
The construction of the Lowari Tunnel has been a long-standing demand of the people there. The project will enhance economic growth through accelerated trade activity, generate employment opportunities for the locals, promote tourism, and reduce travel time for passengers of commercial traffic.
With the increase of transportation, energy, and other infrastructure constructions, the amount of self-drilling hollow anchor bolts are increasing day by day in tunneling projects as a reliable and effective anchorage technology and has shown broad prospects for development and considerable market prospects. Self-drilling hollow anchors can fully anchor the full-length hollow bar and immediately provide support resistance to prevent looseness or deformation of surrounding rock after excavation, which avoids or delays the occurrence of landslides and other diseases during the construction and operation. After anchoring, the hollow bar will be around with a sufficient and uniform protective layer of cement. It will greatly enhance the durability of self-drilling rock bolt and have a long-term recessive benefit.
