PIPE JACKING - A GUIDE TO CURRENT PRACTICE

The article reviews the development of pipe-jacking in the UK and its advantages compared with other tunnelling and pipelaying techniques. It is competitive with segmental tunnelling in the range 900-2550 mm. In all pipe jacking applications, and particularly in bad ground conditions, thickwall, reinforced spun concrete pipe provides a sounder structure than relatively thin, unbolted linings. Developments in pipe jacking techniques have led to jacking rectangular box sections which can provide a greater effective area for such applications as pedestrian subways. Here, such sections provide a lower soffit level than circular ducts for more economic use of space. For large road tunnels, two carriageways can be incorporated into the width of the box sections so avoiding the need for two circular tunnels. Future developments will include greater mechanisation and the design of pipes and joints. (TRRL)
