Classification of Pipe Jacking
Classification can be made by several aspects such as methods of excavation, tunnelface support, jacking force transmission, spoil removal and so on. The nominal diameter of jacking pipe is also used for classification of pipe installation. In Japan, the diameters from 800 to 3000mm are defined as medium to large. The diameters correspond to man-entry size. The diameters from 150 to 700mm are defined as small. An example of classification is shown.
