PERCUSSION PIPE JACKING
Perfect solution for lengths of up to 65 metres on unstable ground such as gravel and boulders.
Percussive drilling system, efficient and versatile technique
The percussive drilling system is a technique that consists of driving a steel pipe by means of a percussive hammer located at the rear.
The hammer, driven by the pneumatic action of a compressor, strikes against the pipe section and the pipe is driven into the subsoil and installed in the ground. This drilling method does not remove the excavated material and it remains inside the pipe.
Once the work with the hammer has been completed, the inside of the pipe is emptied with an auger.
In some cases, a working shaft will need to be excavated in which the bedplate and percussive hammer will have to be installed. The length of this manhole will depend on the length of the steel pipe to be installed.
Drilling characteristics
The percussive pile-driving technique allows the installation of steel pipes of:
LENGTH:
– Minimum lengths: 10-12m
– Maximum lengths: 65m (to be consulted according to the diameter of the pipe to be installed)
DIAMETER:
– Minimum diameter: 508mm
– Maximum diameter: 1.600mm
PRECISION:
Will depend on the ground to be drilled and the length of pipe to be installed. Slopes of up to 1% are possible.
Uses
- Road crossing
- Railway crossing
- Initial casing with steel pipes for the first metres of the Horizontal Directional Drilling to cross the first sections of unstable ground such as gravel.
