Shenbai high-speed railway Houan tunnel is located in Fushun County, Fushun City, the total length of 9125 meters, through the fracture zone of the surrounding rock, complex geological conditions, large water gushing, drainage and ventilation difficulties, cold climate and other factors are limiting the construction progress of Houan tunnel.
Houan Tunnel (inclined shaft) has a perimeter rock grade of 2-4 and a cross section of 12*14m, and adopts the Wuxin double-curved arm rock drill truck double machine and hitting + polygonal blasting to halve the technical solution, which can reduce the number of blast holes bored and the amount of explosives used by 38.7% compared with the traditional construction method.
Double machine hit together + concentrated blasting row of gun halving technology program
Construction equipment
Wuxin new double bending arm drill rigs trucks
4 equipment operators
1 auxiliary worker
Binding Energy Blasting
Controlled blasting using a polyenergy tube wrapped with explosives.
V-shaped polyenergy grooves are opened on both sides of the polyenergy tube.
The concentrated energy effect of the concentrator slot is used to destroy the tunnel surrounding rock.
This enables light surface blasting and precision blasting.
Construction Summary
With the combination of double machines and blasting solution, the number of blasting holes can be reduced from 190~200 to 130, and the over and under excavation can be controlled within 15cm, which can save about 1.6 million of explosive material cost per year, shorten the rock drilling time to within 3 hours, reduce 20~22 workers, significantly improve the tunnel excavation efficiency, reduce the excavation cost, reduce the labor intensity of workers, and improve the economic efficiency. improve economic efficiency and speed up the process cycle.
"People-oriented, creating value for customers" is the unchanging mission of Wuxin Equipment! "To provide customers with economic and efficient construction solutions" is the eternal goal of Wuxin Equipment! Wuxin equipment will do its best to help the 16th Bureau of China Railway Houan tunnel project, making the tunnel construction safer, more economical and more efficient!
