“Normal” bored injection pile with increased bearing capacity

The article discusses modern ways to increase the bearing capacity of piles. A new technology of “Normal” bored injection piles with increased bearing capacity, based on the extraction of a high-strength core and chisel from the body of the pile after its installation, followed by immersion of the reinforcement cage, is presented. The results of pile test with static indentation load, performed according to the traditional “Atlant” technology and the proposed “Normal” technology are presented. The bearing capacity of the proposed “Normal” technology is comparable with that of “Atlant” pile, which makes it possible to reduce the manufacturing cost by extracting a high-strength core and chisel and sinking the reinforcement cage into the pile body.
