At present, three-arm rock drilling rigs are often used during tunnel construction in my country. Due to the complex geological conditions of the surrounding rock at the construction site, and full-section construction is not carried out, the construction effect can be improved by supporting fully

In order to apply mechanized drilling and blasting method for large-section tunnel construction in weak surrounding rocks， construction technologies of rock drilling and arch installation were studied based on Laifu tunnel of Chongqing-Kunming high speed railway. Through the renovation of the

With the rapid development of the transportation industry, the national highway network continues to expand to remote mountainous areas in the southwest. The number of highway projects in mountainous areas is also increasing year by year, and the proportion of extra-long tunnels is increasing.

Drill boom is the positioning and support of drilling, and its performance directly affects the efficiency and quality of drilling. Once the boom stops working, the entire drilling operation cannot be completed. The failure of the drill boom is analyzed and the troubleshooting method is introduced.

For the stratum containing large-sized boulders and boulders within the river course, it is relatively difficult to insert Larsen steel sheet piles into the cofferdam of the bridge foundation. Generally, the pre-piloting process is adopted, and the method of piloting holes and the selection of

The numerical control processing technology is used to process the drilling tool, and the high-precision numerical control processing center is adopted, by matching the special wear-resistant coating cutter, the precision error of each process can be reduced by precise measurement, the production

To resolve the problems of single⁃purpose, low construction efficiency, and low mechanization of the drilling and perforation equipment of blasting methods for medium and large diameter shafts, the ZYL89 vertical shaft drilling rig was designed and developed, based on the technical characteristics

Aiming at the problem that the parameters of the rock drilling rig in open-pit coal mines are only displayed on a single machine, and it hasn′ t the function of remote monitoring and real -time viewing, which lead to the problem of low quality of construction holes, a remote monitoring system for
