Underground Engineering

Underground Engineering is the Foundation of our Experience

According to our good origin, we come from underground and street construction, where we can show more than 45 years of experience. This benefits us in our core expertise, canal construction. Since we deliver a complete service solution – from excavation, via pipe bedding all the way to new street surfaces – which we finalise perfectly to the last top layer.

• Canal and Large Pipes
  
  The in-situ ground builds the most optimal pipe support during pipe driving, since the pipe in its entire cross-section rests ideally in the earth and the in-situ ground is not disturbed.
• Sheeting Systems
  
  For our canal projects we have developed and built the most varying Sheeting systems. A special attention lay here on the absolute strength coherence in the inner-city area, for pipe diameters up to 3.5 metres and depths of up to 10 metres.
• Finished Construction Parts and Buildings
  
  Finished construction parts are core elements of a cost saving and rational way of building. Compared to the cast-in-place concrete construction, they make possible the quick completion of complex construction sections when the planning is done well beforehand. This shortens the product duration significantly. UHRIG plans, builds and delivers finished construction parts just in time.
• Lowerable Manholes
  
  In order to reduce costs for expensive vertical sheeting work and water drainage during manhole construction, the sinking of lowerable manholes is a very economical alternative to local concrete construction or pre-fabricated parts.
• Civil Engineering
  
  Since infrastructures in canal construction are becoming more and more complex, constructive engineering has become indispensable. Since one mostly builds onto the existing construction in canal construction or has to manufacture very large constructions, this can often no longer be realised in pre-fabricated building construction.
• Conduit Tunnels
  
  Conventionally, conduit tunnels are manufactured in complex, rectangular cast-in-place concrete building methods or from semi-prefabricated parts. These have, however, a enormous need of space at the construction site facility.
• Street Construction
  
  Our decades of experience in street construction benefits us today regarding our core expertise in canal construction. Since we deliver a complete service up to the new street surface.
• Ground and Surface Foundation
  
  Although it has already successfully been used on numerous construction sites, a new alternative to the time and cost intensive underground replacement is the installation of lime columns with minimal diameter.
  
• Dynamic Drive
  
  Dynamic pneumatic rams can drive steel pipes with a diameter of up to 4,000 millimetres over a length of up to 80 metres through ground classes 1 to 5. In addition, pipe driving in ground class 6 has a limited feasibility.
