When expanding railway tunnels or rectifying their defects, you will surely have experienced this: The traditional manual or blasting methods are not only extremely slow, but also constantly pose safety risks such as cave-ins and vibrations. The construction period keeps being postponed, and the costs keep rising, causing great pressure on the construction teams. Anxin Drilling has directly addressed this industry's stubborn problem and launched a dedicated Railway Tunnel Impact Milling Machine, combining efficient milling and excavation technology with a stable platform. This has completely revolutionized the construction methods within the tunnels. Our equipment can achieve precise and low-vibration rock milling and crushing, significantly improving the construction efficiency, while also greatly ensuring the safety of the operation and the stability of the tunnel structure, bringing the construction period and costs back under control. This core product is essentially a highly integrated mechanized solution. It fully utilizes and upgrades the value of existing equipment:
It integrates high-performance milling and digging heads, which can easily handle various hardness rock layers in tunnels, and perform operations such as milling, crushing, and contour trimming.
It can work in coordination with our professional Drilling And Splitting Machines. For particularly hard rock layers, it drills first, then fractures, and finally performs milling and digging, forming a complete silent crushing construction process. Three Major Features of the Product
Multi-functional, cost-effective and hassle-free: Based on the modification of excavators or drilling rigs, no need to purchase brand-new equipment. The functions are far superior to ordinary equipment. It can both dig and perform some drilling and crushing tasks.
Safe and efficient, with guaranteed progress: Non-blasting construction, with minimal vibration, almost no disturbance to the tunnel surrounding rock and adjacent structures. The construction can be carried out closely adjacent to the existing line, with a high safety factor and guaranteed daily progress.
Precise control, excellent quality: Adopting a user-friendly hydraulic control system, the operation is like a "surgical operation", capable of precisely controlling the excavation contour, with excellent control over over-excavation and under-excavation, and a flat formed surface.
Tips for Use
Selection matching is crucial: Based on the tunnel section size and the main rock type, select the appropriate tonnage of Excavator Converted Drilling Rigs as the base platform to ensure power matching, without waste or strain.
"Probe - Break - Mill" combined approach: When encountering extremely hard rock, don't let the milling cutter bear the brunt alone. First, use the matching Drilling And Splitting Machines for static splitting, and then mill and clear to achieve higher efficiency and lower wear.
Regular inspection of the cutter disc to maintain efficiency: The milling cutter teeth are consumables. During construction, pay attention to listening to the sounds and observing the slag conditions, and regularly inspect and replace the worn-out cutter teeth to keep the equipment always in the best cutting condition.
