Slurry balance tunnel boring machine is well-suited for geological conditions featuring low groundwater pressure and high soil permeability. Which is widely applied to the operation of road, rail tunnels crossing the river and sea.
⚙️ Description of Slurry Balance Tunnel Boring Machine
NHI’s slurry balance tunnel boring machine adopts the advanced technology of air cushion bentonite, which can control the pressure of tunnel face accurately and reduce the impacts of land subsidence. The cutter can be selected flexibly by the geological condition in order to achieve the maximum efficiency. Moreover, it adopts the proprietary technology of changing cutter under normal pressure, which achieves the safe activities of changing cutter with normal pressure underwater. The core technology of slurry system’s high-pressure scouring can ensure that the cutter cannot be incrusted when conducting soft ground construction. The seal for main drive adopts specific technology. Slurry balance TBM can be operated continually under pressure of 10bar for 10000 hours. This product improves the safety performance and reliability for constructions of large, long and deep tunneling.

Details
The hard rock double shield TBM is a high-performance tunneling machine designed for complex geological conditions, capable of operating in both hard and soft rock.
Details
EPB (Earth Pressure Balance) tunnel boring machines are extensively used for tunneling in confined or pressurized ground conditions. Progressing under pressure, these tunnel boring machines require the use of products with very specific characteristics for optimum productivity in excavating the tunnel at all levels.
