Water transmission pipeline pre-stressed concrete sealing

SWR GmbH carried out fault clearance measures on various DN 800 pre-stressed concrete drinking water transmission pipelines for Netzdienste Rhein-Main in the metropolitan area of Frankfurt.

Work was carried out at depths of up to 5 metres in some cases. Trenches were secured with sheet piles and circumferential waling.

The special sealing clamps were repaired and installed while the pipelines were in operation, thus ensuring that there was no need to interrupt the drinking water supply at any time.
