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. This is the basic idea for the patented pipe installing procedure of UHRIG. The large pipe is laid in a pipe bed, precisely contoured with the adapted pipe outer diameter.
The Pipe Support
The contouring of the in-situ construction ground ranges to the height of the half-pipe; thus, the expensive gusset-backfill work on the underside of the pipe can be omitted. By utilising of the most modern excavator technology and excavator accessory equipment, the UHRIG pipe laying procedure is done completely unmanned, the obstructed trench does not even have to be entered.
The Construction Trench
During conventional open pipe driving, the trenches are left open in their entire length of a piping segment through the long-lasting backfill work. With the UHRIG pipe laying procedure, the newly laid large pipe is filled in again, if necessary with prepared material (see for this, ground preparation according to the UHRIG procedure). Through this patented pipe laying procedure, the construction trench as well as the entire construction site is very small regarding needed space. This makes possible, even with very cramped spaces, very efficient driving.
