ZML160 Multi-Function Drilling Rig: The “All-Round Partner” for Tunnel Construction
In tunnel construction, pipe arch support, core sampling, and advance exploration drilling form an interlinked chain of critical processes directly impacting construction safety and project progress. Under traditional workflows, different stages rely on specialized equipment, not only increasing procurement and management costs but also frequently causing delays due to equipment relocation and workflow coordination issues. ZML160 multi-functional crawler drill, with its core features of “one machine, multiple functions, seamless switching,” breaks through traditional construction limitations, becoming the “all-round collaborative partner” for tunnel construction teams.
As the “safety line” in tunnel construction, pipe arch support demands stringent stability and borehole quality from drilling rigs. Equipped with a high-performance hydraulic power system and precise feed mechanism, the ZML160 effortlessly handles complex formations like fractured, strongly weathered rock and boulder-filled gravel. Its tracked chassis design enables agile maneuverability within confined tunnel spaces, allowing precise hole positioning to ensure borehole accuracy and overall stability for pipe arch support. Whether in soft or hard rock formations, it maintains steady drilling performance, establishing a robust advance support system for tunnel excavation while minimizing surrounding rock deformation risks.
Beyond conventional pipe arch support, the ZML160 demonstrates specialized capability in tunnel core sampling operations. Core sampling is a critical method for understanding surrounding rock distribution and assessing geological conditions, demanding exceptionally high core integrity. Equipped with a dedicated core sampling module, the ZML160 optimizes drilling parameters and sampling techniques to precisely extract intact core samples from various depths. Construction teams can use this core data to promptly adjust support plans and excavation strategies, avoiding construction risks caused by geological misjudgments and providing scientific geological basis for tunnel construction.
Advance exploration boreholes serve as “scouts” for preventing geological hazards like sudden water or mud inflows in tunnels, and the ZML160 excels in this domain as well. Equipped with an intelligent drilling control system, it dynamically adjusts drilling speed and pressure in real-time according to stratigraphic changes, effectively preventing drill jams and burials. Leveraging its exceptional deep-hole drilling capability, it proactively identifies the location and extent of adverse geological formations ahead of the tunnel, granting construction teams ample time to formulate countermeasures. In complex geological tunnel projects, this advance boring capability significantly enhances construction safety, safeguarding smooth project progression.
Compared to single-function equipment in the industry, the ZML160's multifunctionality delivers significant construction advantages. Its modular design allows rapid switching between pipe arch support, core sampling, and advance boring functions, eliminating the need for frequent equipment changes during site transitions and drastically reducing process handover times. Simultaneously, its multi-functional capability reduces the number of devices required, lowering equipment investment and maintenance costs for construction companies. Its intelligent monitoring system provides real-time construction data feedback, enabling managers to track progress and equipment status for efficient, smart management.
From mountainous railway tunnels to urban subway projects, and from complex geological sections to high-risk construction zones, the Sichuan Zhuanshen ZML160 multi-functional drill rig has become a reliable choice for tunnel construction teams with its comprehensive functionality and stable performance. It not only transforms the cumbersome methods of traditional tunnel construction but also drives dual improvements in construction efficiency and safety standards through its “all-around efficiency,” injecting robust momentum into tunnel engineering projects.
