UTILITY TUNNELLING / PIPE JACKING

Pipe Jacking is primarily used to install diameter pipe directly into the ground. The tunnel can be excavated using a variety of methods such as hand mining or a tunnel bore machine. The pipe is propelled into the ground by jacks that are located in the drive shaft. The spoil is transported out of the jacking pipe and shaft manually or mechanically. After each pipe segment has been installed, the rams of the jacks are retracted so that another pipe segment can be placed in position for the jacking cycle begin again.
