Jacking Pipes
Humes leads the industry and develops world class jacking pipes ideally suited for use with modern, closed faced microtunnelling systems.
We provide a comprehensive range of steel reinforced concrete jacking pipes from DN300 to DN3600 in a variety of classes and joint types to suit various applications and installation methods. Reinforced concrete pressure pipes are designed for the combined effects of the external load and internal (in service) pressure. Australian/New Zealand Standard AS/ NZS 4058:2007 Precast Concrete Pipes (Pressures and Non-Pressure) gives a minimum requirement for factory test pressure of 120% of working pressure in the pipeline.
Jacking Technique (Microtunnelling)
Pipe jacking or microtunnelling is a method of tunnel construction where hydraulic jacks are used to thrust specially made pipes through the ground behind a shield machine, from launch shaft to receival shaft.
Pipe jacking is used to install conduits below ground for a variety of applications including: sewerage pipelines; stormwater pipelines; road and rail culverts; pressure pipelines; as a sleeve pipe for other utility pipelines (water, sewage, and electricity and communication cables); and pipe replacement and relining.
