Concrete-filled steel pipe piles are applied to the building of the bases and fencings. They represent piles with the metal tubings core, immersed by pneumomandrel plugs. A steel pipe pile arrange with links in length on 0,5-1,5 m (depending on conditions of production of works) which are joined to the help of electric welding. Concrete-filled steel pipe bearers can be carried out with reinforcing and without reinforcing of a concrete trunk. Steel pipe piles concreting similarly to boring-stuffed piles.

Methods of immersing of pipes at the building concrete-filled steel pipe piles:

• driving down (pneumomandrel plugs)
• cave-in
