Robit’s Successful Test Results in Vietnam

Posted on by Jari Silver

In June 2020, the distributor of Robit in Viet Nam – Dong Loi Equipment & Services Corporation organized a drilling test at Dak Mi 2 hydroelectric tunnel in Quang Nam Province.

Robit and other well-known brands from China and Japan were tested in this site. The test was conducted on a Sandvik DT821 drilling machine with both sides of drill hammer, left and right. The drilling parameters were identical for each brand. The test was conducted to determine the highest working life each tool could reach in the same testing conditions. The structure of tunnel is concrete on the hard rock formation. After a few days, the results of all brands were published. Robit Drifter Rod R32/T38, L=4.9 m completed the service life at 2,300 meters in the left and 3,200 meters in the right of drill hammer. With these results Robit reached from 500 meters to 700 meters better performance than rods by other well-known brands. The customer was very satisfied with the performance of Robit Drifter Rod. They appreciated its quality and will give the priority for using Robit Rod in the future.

Test Location: Dak Mi 2, Hydroelectric Tunnel, Quang Nam Province, Jun 2020

Buiding Up the Longest Tunnel in India

Posted on by Jari Silver

Robit is supplying forepoling systems and MIPL casings  for tunnel roof supporting, and rock drilling consumables for face drilling to RVNL Package – 5.

The Rishikesh–Karnaprayag Railway runs from Yog Nagari Rishikesh railway station in Rishikesh to Karnaprayag. The ₹16,200 crore project will shorten travel time from Rishikesh to Karnaprayag from 7 hours to ~2 hours. A 15-kilometre tunnel, reported to be the country’s longest, will be built between Devprayag and Lachmoli.

The proposed 125-kilometre stretch will have 12 stations, 17 tunnels and 35 bridges. The design consultancy contracts for tunnels are provided by Lombardi Engg, Yuksel, AECON.

The package 5 is being constructed by Navayuga Engineering Company Limited. It consists of 2 tunnels (Tunnel No. 9 & 10). Tunnel No. 9 from Laksh Moli to Maletha is 2.8 km and Tunnel No. 10 from Maletha to Rani Hatt is 4.1 km, including escape tunnels. The current geology found in both tunnels is RBM (soft rock with mixture of sand). The difficulties faced during forepoling and drilling were majorly due to RBM with big boulders of phyllite and quartize.

The NATM method is being used to construct the tunnel. Currently the daily advancement is 6 metres per day. We are proud to report that Robit forepoling systems together with MIPL casings  are approved at RVNL and are being successfully used by the contractor.
