Piling

Reinforced concrete, prefabricated concrete, stone, steel and driven piles have a variety of implementation:
  • deep foundation of buildings, bridges, viaducts etc.
  • landslide rehabilitation, depressions - pile walls;
  • excavation protection, pit protection, slopes;
  • making of wells, shafts etc;
  • temporary supporting and stability actions;
  • remediation of foundation ground.

Procedures of producing a pile are different but they all have in common that with the use of one of possible techniqes (drilling, excavation, vibration or ductile) we make a hole in which we install designed materials (reinforcement, concrete, stone, gravel..) or we directly install different bearing elements (steel or ductile pipes, prefabricated reinforced concrete piles...)

Basic dimensions of piles we produce:

1) Benotto system and drilled piles (drilled with casing or CFA technique):

External casing diameter    [cm] 60 80 100 120 125 150
Inner casing diameter    [cm] 52 72 90 110 115 140
Max. reinforcement diam.     [cm] 42 62 82 102 106 132
CFA – diamater of drill spiral [*] 60 cm 80 cm 100 cm 120 cm - -
* Mark: In the pile made by CFA method the reinforcement is installed after finished drilling and concrete instalation through hollow spirals.


2) Minipiles (spirals and DTH hammers):

External diameter of casing    [cm] 25 41,9 52
Inner diameter of casing    [cm] 23,4 39,4 49,5
Diameter of spiral/DTH hammer [cm] 22/21,9 37,5/37,5 45/44,5
Max. reinforcment diameter    [cm] cevi f16 31,5 39

3) Driving prefabricated, prestressed elements – pilies dimensions 30/30, 35/35 and 40/40 cm and hexagonal reinforced concrete elements of diamater 70 cm.
 
4) Driving steel pipes with flat bottom, diameter up to 80 cm.
 
5) Driving ductile pipes dimensioning:

Thickness of pipe    [mm] External diameter of pipe [mm]
118 170
7,5
9
10,5
-
9
10,5
Max. diameter of crown plate [mm] 250 320

6) Vibrated piles. With vibrator of diameter 40 cm we produce stone piles or injected stone piles diameter up to 100 cm depending on soil conditions or concrete piles with possibilitiy of installation of reinforcement cage diameter  cca 24 cm.
