Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional “hand mining” in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in heavily urbanized areas.

Product Description:

The TERRATEC S23 and S24 EPBM TBM are 6.61M in diameter and include state-of-the-art features such as the 900kw VFD electric driven CutterHead. They have a versatile design for either excavating soft ground with cutting tools or mixed ground and rock using up to 33 number 17″ roller disc cutters. Both TBMs have active type articulation and 2-component grout backfilling systems.

Application: The Slurry-Water Balance Micro tunneling machine can be used under conditions of high groundwater pressure and a wide range of soil qualities. The applicable pipe diameters are in the range of φ600mm to φ4000mm. Both Steel and RCC pipes can be laid.
