Brief introduction of product series:
For producing Hard-rock TBMs, CRCHI makes full use of abundant experience of tunnel construction, develops its own advanced system integration technology and attends the National 863 Program’s TBM science & technology support project. Now CRCHI has already used the most advanced designs and testing measures in terms of excavation, muck discharging and tunnel lining and other TBM key technologies, overcoming more than 30 technological difficulties in TBM’s design, manufacturing and service like long service time, consecutive advancement, design of high-power big-torque drive system, tunnel lining, high-energy vibration active control, automatic correction of deviation of TBM posture, the preparation of high-strength wear-resistant materials. CRCHI has fully acquired TBM’s design, manufacturing as well as technology application, breaking dependence on foreign products and technologies with regard to hard-rock tunnel construction. Hard-rock TBMs are widely used in rail transit project, water resources and hydropower project, coal mine shaft project.
Open-type TBM, Single-shield TBM, Double-shield TBM
Advance borehole drilling; advance support; direct observation of lithology change; easy to draw geological map.
Hardox plate, composite chromium-carbide wear-resistant plate as well as hard alloy block with high wear resistance are materials of the cutter-head, which ensures long service time.
Double row cylindrical roller thrust bearing is used in the masterdrive, ensuing long service lifetime and high safety.
Reliable and high-efficient PLC control system, real time on-line monitoring and data collection
Innovative multi-material transport system ensures safety and high efficiency in the process of material transportation.
Equipment is easy to dismantle and install due to proper allocation of equipment.
Foam system with single tube and single pump performs reliably and its injection parameters can be consecutively adjusted.
