Müller Verpress (MV) piles

MV piles are piles with a very large tensile capacity that can be used vertically or at an inclination. They are, basically, steel beams that are driven into the soil by means of a hydraulic vibrator. The vibrator can also be used under water. During pile driving, grout is continuously injected at the pile tip by means of usually two lances connected to the beam. The grout ensures significant shaft friction after hardening but also low friction during installation. The piles can be up to 70 metres long. VSF has driven MV piles serving as anchorage for various quay walls in the port of Rotterdam. The working load of the piles amounted to a maximum of 700 tons but the test loads were significantly higher. VSF also installed MV piles as vertical anchorage of concrete floors of building pits, with the piling rig positioned on a traversing bridge or a pontoon. The rig was equipped with a special leader to follow the hammer to pile the piles under water without excess pile lengths.

Application

Anchorage of quay wall and building pit floors. 

Ambient factors

Pile-driving produces noise and vibrations that could cause nuisance for the surrounding area. With MV piles, there is relatively little risk of compaction of the subsoil. In general, the equipment used is large and requires a lot of space.

Pros and Cons

  • Very high pile loads possible
  • Large equipment necessary
  • Noise and vibrations during installation
