Our company has independently developed a new type of arch frame installation and drilling rig machine, which features simultaneous functions of arch erection, anchor bolt drilling, and grouting. Without needing to leave the site, this equipment can complete the three processes—arch erection, anchor bolt installation, and grouting—in a synchronized manner. As a result, work efficiency is improved by more than 50% compared to conventional methods, the number of construction workers required is significantly reduced, and the safety index is markedly enhanced.

Product Introduction

　　Our company has independently developed a new type of arch frame installation and drilling rig machine, which features simultaneous functions of arch erection, anchor bolt drilling, and grouting. Without needing to leave the site, this equipment can complete the three processes—arch erection, anchor bolt installation, and grouting—in one go. As a result, work efficiency is improved by more than 50% compared to conventional methods, the number of construction workers required is significantly reduced, and the safety index is markedly enhanced.

　　Applicable scope: Suitable for various working methods including three-step, two-step, micro-step, and full-face operations;

　　Three major processes: scaffolding, anchor rods, and grouting;

　　Nine key functions: under-excavation treatment, charging, support installation, anchor mesh welding, foot-anchoring bolts, system anchors, advanced pipe sheds/casings, high-pressure grouting, and prestress application.

Structural features

　　Integrated rigid engineering chassis, four-wheel drive, bidirectional driving design, electric-powered construction, diesel-powered emergency operation—each of the three arms features a rotating, foldable, and telescopic structure. The working radius of the dual-side arms is significantly greater than that of other products. The three-arm, three-gripper configuration is equipped with a high-power rock-drilling system featuring dual anchor rods, enabling a maximum drilling depth of 4.1 meters and supporting the installation of 4.5-meter drill rods. The maximum lifting capacity per arm is 3 tons, and the grouting capacity can reach up to 4 cubic meters per hour.

Significant advantage

　　1. Green: low energy consumption, zero emissions;

　　2. High Efficiency: The system requires only two operators and one auxiliary worker per machine. During construction, vehicles do not need to be moved, saving 2 hours per cycle in setup and transition time. Setting up the arch takes just 50 minutes. The left and right drilling rigs can simultaneously perform operations for foot-anchoring bolts and systematic anchor bolt holes. A high-power hydraulic rock drill is employed, with a maximum power of 2 × 18 kW and a drilling speed of 2 m/min. A large-capacity grouting pump delivers 4 m³/h, with dual-grouting lines, doubling the efficiency. Additionally, the arch-support arm is equipped with dual breakers for handling under-excavation and hazard removal.

　　3. Smart: Remote control and automatic data collection and upload;

　　4. Safety: When drilling arch supports and anchor bolt holes, a prefabricated steel mesh is installed above to provide protection, reducing the number of workers on the working face by approximately 70%.
