Abstract

The article discusses the installation of one of the largest known slurry pipe jacks in the city of Fujisawa, Japan. The aim of this project is to control sewage water in the rainy season. The main pipeline of the sewage system was excavated using the slurry pipe jacking method to a diameter of 3.53 m. The 791.97 m long tunnel required a gradient of 1.3%.The tunnel construction period was from April 28 to August 31, 2003. The characteristics of the pipes used were 3.5 m o.d., 3.0 m i.d, with each being 2.43 m long. The Fujisawa sewage tunnel project passes under an overcrowded urban area and because of this, during the construction period, it was important to control ground settlement carefully. On the boring machine used for the Fujisawa project, a DKI-manufactured system was installed instead of a lubrication system and remote controlling of the machine. The Fujisawa project has been hailed as one of the most successful slurry pipe jacking projects in Japan and was completed on schedule.
