In the amplified bond anxiety resultant in the simultaneous drilling and grouting Procedure, Hollow Bars will be the reinforcement bar preference in collapsing soil conditions.
For rotary bore method, big excavated holes are current through design that may pose a security chance
To attain the desired ability, the hammer rig continually impacts the top in the pile. With Each and every blow a reference mark is scribed around the aspect with the pile. With Every single subsequent blow, even more reference marks are scribed Therefore the displacement with the pile with Each and every blow is often measured.
