Customized solution for tunneling problems: efficient milling solutions reshape railway tunnel construction
Railway tunnels pass through mountains and ridges, and hard rock strata are a huge challenge for builders. Traditional construction methods are inefficient, costly, and have potential safety hazards, which seriously restrict the progress and safety of the project. Faced with complex and changing geological conditions and strict construction requirements, how to achieve safe, efficient, and accurate rock crushing has become your core pain point.
We are well aware of the difficulties in tunnel construction and customize milling solutions for hard rock tunnels. With modular design concepts as the core, high-performance Drilling Rigs, high-efficiency Excavator Converted Drilling Rigs, and powerful Drilling And Splitting Machines are flexibly integrated. The solution is not a stacking of equipment, but a deep collaborative optimization based on geological data and construction goals - either precise drilling to pave the way for subsequent blasting, or directly using modified drilling rigs to efficiently drill holes in narrow spaces, and the Drilling And Splitting Machine can be called to implement "drilling-splitting" precision strikes on stubborn rock bodies, greatly reducing disturbances. Its value lies in significantly improving the single-cycle footage, reducing the overall cost, and ensuring the safety of construction personnel. Its character is like a precise Swiss Army knife, strong, flexible and reliable.
Practical application has proved that this solution can increase the drilling and blasting efficiency of hard rock tunnels by up to 30%, increase the progress of non-explosive mechanical excavation by 25%, make the excavation profile more accurate, effectively control the over-excavation and under-excavation, and comprehensively improve the construction safety factor.
Core equipment is precise:
High-precision drilling rigs (Drilling Rigs): Equipped with advanced guidance systems, the drilling accuracy reaches ±1°, specially designed for precise pre-splitting holes and advanced support holes (such as pipe sheds), and is the cornerstone of tunnel contour control and pre-splitting blasting effects.
Flexible modified drilling rigs (Excavator Converted Drilling Rigs): Modified using mature excavator platforms, they are highly maneuverable and can quickly implement operations such as anchor holes and grouting holes in confined spaces such as the face, side walls, and inverts. The hole diameter covers 100-200mm, greatly improving the efficiency of auxiliary processes.
High-efficiency Drilling and Splitting Machines: Integrate drilling and static splitting functions. Drill a specific deep hole first, then insert the splitter to generate a splitting force of up to 350 tons, so that the rock mass breaks from the inside. It is especially suitable for urban tunnels where blasting is not allowed, tunnels near buildings, or key areas that require fine crushing, safe and efficient.
Application scenario highlights:
Precise pre-splitting and slotting hole construction in hard rock tunnel drilling and blasting.
Contour-controlled drilling of tunnels with complex sections (such as super-large sections and special-shaped sections).
Rapid hole formation of support structures such as tunnel pipe support and system anchors.
Non-blasting safe removal of local stubborn rock or boulders in tunnels.
Mechanical excavation of tunnels in environmentally sensitive areas (such as urban areas and adjacent important structures).
Product features and tips:
Features: Geological intelligent matching - the solution deeply combines the previous geological survey data and dynamically adjusts the equipment combination and construction parameters.
Features: Efficiency aggregation - Drilling and cracking equipment work together to break through the bottleneck of single equipment capacity.
Tips: For hard rock, choose the drilling and cracking combination first - facing extremely hard rock or explosion-prohibited areas, the drilling and cracking machine is the first choice for efficient and safe rock breaking.
Tips: Use modified drills for limited space - For narrow or special-shaped working surfaces, the flexibility of excavator modified drilling rigs is irreplaceable.
Choosing a customized milling solution is a strategic choice to break through the constraints of hard rock in railway tunnels. It is not only an upgrade of tools, but also an evolution of the concept of tunnel construction - with precision, efficiency and safety as the core, reshaping the power and wisdom of tunneling through hard rock
