Pipelines constructed in the tunnel method
- Disasterproof placement
in underground (30-100 m depth)
- Long lifetime of pipelines
- Short lengths of lines
- No extensive approval procedures
- Limited real servitude
- Work at central points only
- No interferences from outside
- Extensive storage volume
- Easy to operate due to favourable
the Hardcore Filling Procedure
- Optimal placement qualities
due to a continuous cycle of pipeline construction allowing even for
- As the filling performance
exceeds by far the daily progress in pipeline construction the filling
process can start at a much later time.
- No disposal of excessive
filling material. Subsequent pressing
and filling are done simultaneously at regular times.
- Cleaning requirements are
- Staff requirement is low.
- The construction period
is sharply reduced.
- The costs of pipeline construction
and hardcore filling are brought down considerably.
Experiences from previously
completed projects are showing the following:
The system and procedures are extremely economical and can be applied
for all kinds of pipes. Operations can be prepared as required on the
construction site. Constant supervision is required, however.
The system and procedures
are highly attractive for investors in the field of supplies.
We consider pipeline construction
and hardcore filling of the ring space as an integrated concept offering
a great potential for substantial improvement and extended lifetime
of the pipeline gallery. The economic advantages and the high pipeline
quality remain on the side of the investor provided our office is involved
already in the planning stage of your construction project.
