punching machine in the process of the construction ofcommon problems and solutions ( a )
how toprevent and cure bored pile deflection?
1,quality problems and phenomena
1) into thehole is not vertical, deviation value is greater than a specified l/100.
2) reinforcing cage can smoothly into the hole.
2, cause analysis
1) impact drill is not in a horizontal position, or construction site without leveling and compacting, during the drilling process, theoccurrence of uneven settlement.
2) waterdrilling platform base is not stable, not at the state level, in the process of drilling, drilling machine rack of uneven deformation.
3) drill pipe bending, loose joints, resulting in a large range of bitrock.
4) in the old buildings near theborehole obstacles encountered in the process, the bit to the side.
