Cylindrical piles for hard and\/or unstable soil layers<\/h2>\n\n
The new cylindrical full displacement pile<\/a> (Olivier DPA) allows construction on both less load-bearing and hard soil layers. The pile can be drilled without vibrations, even through layers of sand. In the case of large pipe diameters, the auger head is shorter than traditional FPD auger heads, resulting in less friction and significantly lower required drilling torque. This enables faster and more efficient work with considerably less fuel consumption during drilling. Additionally, the new system has the added advantage of eliminating the need for grout injection in hard sand layers. With smaller pile diameters, such as 360 mm, larger reinforcement cages can be placed through the drilling pipe. This is made possible by using a feed pipe with a diameter of 324 mm along its entire length. Numerous comparative tests with existing traditional systems have sufficiently demonstrated the speed and efficiency of Olivier’s new cylindrical pile system.<\/p>\n\n Thanks to the unique flaps system<\/a>, the drill tip is no longer lost and can be reused each time. The drill tips no longer need to be manually placed, reducing the risk of accidents and injuries significantly. Furthermore, the reusable drill tip results in significant cost savings and reduces the need for transportation to the construction site, leading to reduced emissions. This is especially important considering that in Belgium alone, over 150,000 drilled displacement piles are made annually.<\/p>\n\n The patented flaps also ensure more precise positioning of the auger head. Installing the reinforcement and pouring concrete becomes a breeze as a result.<\/p>\n\n A further innovation is the new patented automatic Olivier coupling<\/a>, which is mounted under the rotary drive. This speeds up and ensures the safety of connecting the pipes to the machine, eliminating the need for anyone to climb to great heights to lock the coupling. In full displacement piling systems, the coupling can be used on pipes ranging from 133 to 914 mm.<\/p>\n\nUnique flaps system with reusable drill tip<\/h2>\n\n
