Tunnel Boring Machines (TBM's)

Tenbusch TBM on Job

At Tenbusch, we design and manufacture tunnel boring machines (TBM's) and TBM systems.

  • Custom designed specifically for the customer's application,
  • For both liner plate and pipe-jacking applications,
  • Available as a stand alone TBM unit or delivered as a complete system.

We build all the equipment needed for a complete tunnel boring machine (TBM) system:

TBM Unit

We design and manufacture custom tunnel boring machines (TBMs) for pipe-jacking and liner plate applications. Our tunnel boring machines (TBM's) provide several benefits:

  • Achieve high rates of tunnel excavation and spoil removal,
  • Provide hydraulic powered steering and grade control of the pipe insertion or liner plate tunnel,
  • Allow for tunnel excavation to progress in the front of the TBM while liner plate is assembled at the rear of the TBM (for liner plate installations),
  • Custom TBM's available with removable power units.

Here at Tenbusch, we design and build custom TBM's with removable power units. For more information about employing a removable HPU for you applications please see our recent article:

Conveyors

We design and build custom conveyors for tunneling and pipe-jacking operations.

  • We build heavy duty conveyors appropriate for tunneling applications,
  • Mechanized conveyors transport spoil from the floor of the tunnel face and convey it up and into the muck cart,
  • Our custom conveyors enhance spoil removal rates and improve productivity,
  • Tenbusch conveyors can be transferred to other shields for other tunneling or pipe-jacking projects,
  • Tenbusch conveyors are custom built according to the customer's specifications and job site conditions.

We have a short video that shows the operation of a Tenbusch shield conveyor:

External Hydraulic Power Units (HPU's)

We build hydraulic power units that are designed for tunneling and pipe-jacking operations. Our hydraulic power units are designed to provide continuous and reliable power to your equipment. Typical features of our HPU's include:

  • Robust protective frame for rough tunneling job environments,
  • Electric motor or combustion engine power source,
  • Multiple pumps for main, auxiliary, and filtration circuits,
  • High capacity hydraulic reservoirs matched to underground equipment applications,
  • Controls to match your requirements and appropriate monitoring equipment and gauges.

Underground Lubricant Systems

We design and manufacture custom lubrication systems for tunneling and pipe-jacking applications. Tenbusch lubricant system features:

  • Used to mix and pump underground lubricants such as bentonite and polymer,
  • Significantly reduces the friction load on the pipe surface - cutting power and thrust required for installation,
  • Our units are designed for maximum utility and ease of use,
  • Our lubricant systems are normally powered by an separate hydraulic power unit (HPU), although units are available with an integrated power source.

Tenbusch power units are designed and built specifically for eliminating job risk by reducing the overall thrust requirements for tunneling and pipe-jacking applications. Our units can be customized as needed.

Intermediate Jacking Stations

We design and manufacture intermediate jacking stations for tunneling and pipe-jacking applications. Tenbusch intermediate jacking station (IJS) features:

  • One or more units may be used to reduce the overall thrust required for jacking pipe strings or culvert tunnels,
  • Tenbusch IJS units are designed with reusable cylinders and components,
  • Our intermediate jacking stations are designed for maximum utility and ease of use,
  • IJS units are built to our high quality standards.

Tenbusch IJS units are designed and built specifically for eliminating job risk by reducing the overall thrust requirements for tunneling and pipe-jacking applications. Our units can be customized as needed.

Backstops (Thrust Walls)

We design and manufacture backstops (thrust walls). Backstops provide a broad, portable, and easily transported mass which distributes thrust and minimizes deflection and drift of heavy equipment in tunneling and pipe-jacking operations.
