PIPE JACKING IN WATER-SATURATED GROUND. SECOND INTERNATIONAL TUNNELLING SYMPOSIUM, MUNICH, 12 APRIL 1989

This paper describes the use of pipe jacking in utility and waste tunnels in West Germany, and discusses the conditions under which it is most useful. About 25% of the tunnel kms, constructed in West Germany during the last few years, are utility and waste tunnels; about 75% of these tunnels were constructed predominantly using pipe jacking. Hydraulic pipe jacking has been especially useful where difficult geological conditions are met in loose soil near the surface as well as in rock. Pipe jacking is applied in the ground water zone when it is not possible technically to use open trench pipe laying involving lowering of the ground water level. Pipe jacking is also especially suitable for tunnels beneath water courses. The driving of curved alignments is possible. For excavating soil at the face, it is possible to apply conventional methods in addition to those specially developed for pipe jacking. Special precautions must be taken against blowout when using compressed air. Particular attention must be paid to the joint design in the pipeline, to prevent soil penetrating the tunnel through open joints. The designs developed have been tested successfully in many extensive tunnelling projects. The German title for this paper is as follows: "rohrvorpressungen im grundwasserbereich". For the covering abstract of the conference see IRRD 824157.
