Pipe jacking is a micro-tunnelling technique developed primarily to build foul and surface water.
Pipe jacking is a micro-tunnelling technique developed primarily to build foul and surface water drainage, although it is used in a wide range of other applications such as infrastructure access under, for example, rivers.
Compared to traditional open cut methods, pipe jacking has numerous advantages. There is minimal disruption to traffic flows and less damage to existing utility pipe and cable infrastructure. From an environmental perspective, pipe jacking leads to fewer vehicle movements and less excavated material going to landfill.
Superlit’s GRP jacking pipes are:
- Strong: they have a high compressive strength.
- Lighter: easier to handle on site (could do with some information on weights)
- Lower friction modulus: longer jacking lengths can be achieved. (is this correct? Could do with some comparative figures)
- Thinner wall thicknesses: often enables a smaller pipe to be used to achieve the same system capacity.
The cumulative economic benefits achieved from specifying Superlit’s GRP pipes can be considerable:
- Faster installation: less time on site, less disruption
- Smaller excavations: quicker, reduced material storage, less material to landfill
- Flexibility in system design: the low and constant modulus of elasticity (E) enables GRP pipes to follow a curved path.
- System performance: the internal surface of GRP pipes is exceptionally smooth providing exceptional hydraulic performance. The specially designed rubber and steel couplings (see diagram) minimise the potential for leakage.
