Hollow piles in steel: |
|
|
|
|
|
340 micro-piles in steel tube, length 15.30 m, DN 193.7 mm, were installed as shoring for the construction pit. Each of these piles is fitted with 2 loops (4 pipes) of HDPE piping 20/2.0 mm.
Total length of piping: 20,000 m
The 111 circuits incorporated in the pile system are connected to 5 submanifolds which are in turn connected to the main manifold in the building services centre via flow and return lines. |
