Underground drainage pipework – AK St. Georg
The side of the Asklepios St. Georg hospital was completely renovated. For this purpose the drainage system, which consisted of partial and mixed piping in which all drainage water (wastewater and rainwater) was drained off in common pipework, was reconstructed. The mixed water pipework is linked together with 40 buildings, 2.7 km of main pipework, 3.5 km of connecting pipework and around 200 shafts on the premises, which has an area of 8.5 ha.
This meant that all drainage collection lines and manhole shafts required modernisation during the construction measures. For this purpose, some of the old lines and shafts were abandoned and appropriately backfilled. The newly-constructed pipework and shafts consist of high-resistance polypropylene and was connected using electro-welding joints. The technology used meant that an absolutely seal tight and extremely resistant long-term system, which can accept all drainage from the roof surfaces, the surrounding sealed areas and the commercial and domestic drainage water arising from hospital operations, was installed.
The restricted space and vicinity to the buildings required a type of open trench construction which inhibited vibration in order not to affect hospital operations.
