Description
The puncture method consists in radial compaction of the soil when pressing a pipe with a conical tip.
The sequence of works:
- - open the acceptance panels and install the jack
- lay the first link of the pipe with a conical nozzle
- verify the horizontal position of the pipe
- push the link into the length of the rod
- after the first link, weld the second and repeat the operation
This method is used to lay pipes up to 500 mm in well-compressible soils.
In sandy soils, it is necessary to apply vibration for the first link and the diameter of the pipes is not more than 300 mm.
