Structures in rocks and soft ground
Structures in rocks and soft ground constructed in mined or cut and cover methods have always been the centre of PSP’s engineering services, such as:
- tunnels for railways and roads
- pipe jacking
- excavation pits
- jet grouting
Shield driving with segmental lining
Since the foundation of PSP a centre of activity has been the method of shield driving with segmental lining. In this special field PSP is to be found among the leading engineering offices in the world.
A lot of consulting and checking of designs as well as design work is being and has been done by PSP for planned projects, projects under construction and also completed construction activities.
Geothermics in Tunnelling
In recent times PSP is also working intensively on geothermal aspects in tunnelling. The development of special precast geothermal energy segments is one focus of he research and consulting works. Research activities with university institutes are dealing with test fields of tunnel shellswith shotcrete and insitu-linings
