Bored Piles Large diameter bored piles of concrete or reinforced concrete are an economical means of supporting high structural loads with minimum settlement. Brochure 20-01EN Bored Piles Grafik: BAUER Drilling tools for application in all types of soil drilling auger for stiff or medium dense soils Piles are a powerful, state-of-the-art construction element with many applications in civil engineering and building. As contiguous, or secant pile walls in water bearing soils they are used to secure deep excavations or retain slopes. In piled foundations they are used at various diameters as single piles or pile groups. Depending on the application, all bores are either concrete filled (with or without reinforcement), or filled with removed spoil. Occasionally steel sections are inserted as plunge columns or in cases of high lateral load. Grafik: BAUER Construction methods Kelly bored piles FOW Drilling We can install Kelly piles using augers or core barrels in the common diameters 620, 880, 1180 and 1500 mm. The piles can be installed to depths of up to 40 m either vertically or inclined, with casing, or with suspension support. Grafik: BAUER core barrel for cutting rocks Using a special rig, front of wall (FOW) piles with diameters of 406 or 508 mm can be executed to a depth of up to 12.5 m – allowing work close to buildings or walls. box auger with cleaning edge Continuous Flight Auger Drilling We execute CFA (continuous flight auger) piles with diameters of 430, 550, 630 and 880 mm to a depth of up to 26 m.

Construction process Drilling Grab excavations In Alpine regions we use grab drilling with diameters of 880 and 1180 mm. Reinforcement Quality Assurance 3 1 Large diameter bored piles usually have to withstand high loads, and we therefore use a variety of qualityassurance methods for our products. 2 Digital recording and logging of the execution parameters 4 Applications 1 Foundations Large diameter bored piles are particularly effective in transferring high loads. They are thus excellently suited for foundation works in nearly all types of soil. Integrity testing 2 Stabilisation of excavation pits In inner-city areas it is essential that the spaces between buildings are fully utilised. Piled walls are an established method of retention on the boundary or close to adjacent buildings. They can be combined with other geotechnical solutions such as Jet Grouting to form near water tight pits. 3 Slope Stabilisation Slope stabilisation is necessary to prevent landslides and protect existing buildings and structures. Here, large diameter bored piles are regularly used often combined with other techniques such as ground anchors or soil nails. Pile loading tests Pile-cap settlement (mm) Load (MN) 4 Infrastructure Whether in tunnelling, in road or bridge construction or in measures for flood protection, large bored piles can be used in a multitude of ways and are often found in infrastructure projects.
