  • Here you can see the main equipment for the Kelly drilling. First the Kelly bar with the mast and the rotary drive on the left side. On the right side there are some pictures of different tools for removing the spoil which are attached to the kelly bar. Depending on the soil conditions augers, buckets or core barrels are chosen.
  • First of all, there are the Bored or Driven Piles for foundation piles or retaining structures. In the next chapter we will talk in more details about piling works.
  • I don‘t know how many different method for the pile installation and how many different piles itself exist. But for sure this list can be continued for quite a lot of pages. We will limit the presentation to our standard bored piles. Generally we are offering to products for the piling works. First is the Rotary Drilling with Kelly and Second the Rotary Drilling using continuos flight auger. But what does this mean?
  • Also the pile installation has to be adopted to the soil conditions.
  • Here I have to tell a story: In the year 1958 Bauer had to construct a tied back retaining wall on a site in Munich. At that time anchors were installed in a completely different way then nowadays. First shafts had to be drilled behind the proposed line of the wall and excavated about ten meters deep. Then the anchors were drilled and finally fixed from the inside of the wall. Unfortunately on that site the crew missed the shafts when drilling the anchors. But the real problem started when the tried to withdraw the drill rods. This attempt failed and the forces to pull out the rods would have been even bigger then the required forces for the retaining wall. And by chance a new method was born - if the forces are so big, why not anchor the wall by leaving the drill rods in the ground. This was the beginning of the grouted anchor. Today the installation of grouted anchors is quite easy and not more than a standard procedure.
  • Ground improvement by the injection of bentonite cement slurry or chemical solutions is only efficient in granular soils and used for sealing systems. In our overseas department we are mainly offering grout curtains for the constructions of pits or dams to improve the permeability of rock. In the last years this field became more and more important.

    20. 20. Drilling with Continuous Flight Auger (CFA) Beton Drilling with CFA auger. Soil is continuously transported from the tip of the auger upwards by the flights. The borehole is stabilised by the auger filled with soil. After reaching the final depth the auger is withdrawn and concrete is pumped through the hollow stem with the concrete pump. Remove the excavated soil with a hydrau- lic excavator. Push or vibrate the reinforce- ment cage into the freshly poured pile.

    23. 23. Ductile Driven Pile System Pipe joint, comprising conical socket and spigot Head plate fixed to the pile head The driving shoe ensures that cobbles and other small obstructions are displaced or crushed when necessary during driving
    24. 24. Ductile Driven Pile System Skin friction pile: Cement grout is pumped through the ductile pipe during pile driving and injected continuously through the driving shoe. Excavated grouted section of a skin friction pile: BAUER ductile pile foundation immediately adjacent to an existing building
    25. 25. Ductile Driven Pile System Advantages over other Foundation Techniques · Short installation period · Simple site set-up · Minimal requirements with regard to working platform and access · No additional site traffic due to suppliers · No drill spoil · Minimal wastage due to adaptability of ductile pipes · No work required on pile head, piles are immediately cut back to their exact cut-off level with a disc cutter · Very low wear and tear on equipment Ductile piles being installed in the Hotel Summit Golf & Resort in Panamá
