Advanced Precision Cutting: To ensure that the cutter head remains in good condition for a long time, the Q460C low-alloy steel base was used for it, and tungsten carbide cutters were also used to allow for efficient cutting.
Adjustable Diameter Design: Variable diameter TBM, which can be from 4 to 15 meters, is a combination capable of meeting a variety of tunnel requirements.
Multiple Operating Modes: It is equipped with both EPB and slurry TBM modes to be able to deal with the complexity of the ground in any of four.
Powerful Thrust Performance: The maximum advance speed of up to 80 mm/min to guarantee finishing projects on time with the thrust pressure is 35-40 MPa.
Intelligent Monitoring: A real-time data gathering and monitoring system, that besides raising safety also raises operational control to a higher level.
| Conventional Tunneling | Zhongda TBM |
| Long construction cycles and heavy labor dependence | Automated thrust system, advanced speed up to 80 mm/min, shorter project duration |
| Low efficiency in complex soil and rock conditions | Adjustable cutterhead adapts to varied geology with stable output |
| High labor costs and safety risks | Intelligent monitoring system improves onsite safety |
| Complicated transport and relocation | Modular design for easy transport, assembly, and relocation |
Since the ground was a combination of soil and rock, the construction teams for tunnel projects in Southeast Asia and the Middle East were Unable to identify a Method that was both reliable and efficient. Traditional methods were not only inefficient and extremely lengthy, but they also resulted in inconsistent muck discharge, which made the coordination of downstream operations more difficult.
The customer went for a fully customized Zhongda TBM whose diameter was exactly that of the tunnel geometry. The machine was equipped with an adjustable EPB/slurry cutterhead and an intelligent monitoring system that allowed an accurate advance level and stable muck discharge.
Modular Shield Tunneling Machines are tailor-made to make the movement easier and quicken the assembly on the spot.
Very precise cutterhead and high-thrust hydraulic system to maximize advanced efficiency.
Smart monitoring and control to guarantee uninterrupted, stable operation of the ground even in complicated strata.
Efficiency was improved by around 35%.
Continuous discharge of muck resulted in the continuity of the workflow.
Overall, the project expenses were reduced, hence allowing a higher return on investment.
"We really have had a very good experience using the Zhongda Medium-Diameter Shield Tunnel Boring Machine. It is a very big step for us, and we realized progress, stability, and a massive decrease in construction time straight away. Our work efficiency, as a whole, has been significantly improved.”
