In China's railway tunnel construction,the drilling-blasting method dominates with an application rate exceeding 70% and is gradually developing towards fullprocess mechanized operation. Drilling jumbos are the key equipment in mechanized drilling-blasting construction, and their configuration

Facing the challenges of high-speed railway tunnel projects, which involve complex geology, high safety risks, and strict quality requirements, a mechanized construction technology system for long tunnels has been proposed. It introduces key equipment and technologies like the three-arm rock

This article, in combination with the construction characteristics of the No. 3 inclined shaft of Fengshun Tunnel, provides a detailed explanation of the construction technology of the three-arm rock drilling jumbo. It compares the excavation construction of the rock drilling jumbo with traditional

This article compares manual operations and multi-arm drilling jumbo blasting in terms of technology, quality, drilling, economy, and safety, mainly providing a detailed comparison from aspects such as construction processes, construction characteristics, and personnel allocation. It ultimately

Under the background of intelligent construction in engineering, tunnel construction technology is transitioning toward systematic intelligence. This paper takes the Donghanjia Tunnel of the Shenbai High-Speed Railway as an example, integrating the ZYS113 fully computerized three-arm rock drilling

To address issues such as the inability of humans to install long anchors in weak surrounding rock tunnels and the high cost of specialized foreign equipment, a technical method for installing self-advancing long anchors using a drilling jumbo is proposed, taking the soft rock large deformation
