Safe Water Supply in the Czech Republic Thanks to HOBAS Protective Pipes

Protective pipes from CC-GRP are often employed to protect potable water pipes and sewers running beneath busy roads, but most often crossing a tramway or railway. Here they hold a dual function: On the one hand they protect the carrier pipe from static and dynamic loads and on the other they facilitate rehabilitating or replacing old lines by means of trenchless installation.

Czech Republic
Also the Czech Republic has been opting for HOBAS Pipes to protect water supply lines. The existing potable water pipe in the Region Ostrava, for instance, runs beneath highly frequented railways and could no longer hold out against the dynamic loads. The client set about looking for a suitable pipe material with high static and dynamic load capacity and which is insensitive to aggressive soils and other negative influences from the former mining area Ostravsko-Karvinská.

HOBAS GRP Pipes are being installed in the Region Ostrava for more than 20 years. Thanks to their corrosion resistance and relatively thin wall thickness but high stiffness they presented an ideal solution also in this project.


Sichere Wasserver- und entsorgung dank HOBAS Schutzrohren

Bei Straßen mit hohem Verkehrsaufkommen, vor allem aber bei Straßenbahn- oder Eisenbahnkreuzungen, werden Trink- und Abwasserleitungen oft in einem Schutzrohr aus GFK verlegt. Dabei übernimmt das Schutzrohr eine Doppelfunktion: einerseits schützt es die bestehende Rohrleitung vor statischen und dynamischen Lasten, andererseits wird dadurch die Renovierung oder der Austausch der alten Rohrleitung durch grabenlose Bauweisen erleichtert.
