8) broken pile handling process, segmentation get stake to depth of implements
Broken pile segmentation in this joint sleeve pipe is taken out, after first paragraph cuts, more fixedly connects second section sleeve pipe with bolt, continue convolution press-in, repeat above-mentioned rupturing operation, until take out remaining whole old stake;
9) rise and pull out sleeve pipe, backfill operation
After clear stake completes, rig convolution promotes, and segmentation rises pulls out sleeve pipe;
10) main engine bed alignment pin remove, ferry construction
An old stake is reorientated after pulling out, and pile pulling device moves to next stake ferry construction, until complete all pile pulling tasks in place.
Because pile body has reinforcing bar, realize twisting off pile body, the condition of two aspects must be met: the moment of torsion that 1. drilling equipment produces must be greater than the opposing moment of torsion of pile body self; 2. sleeve pipe and the soil body have enough frictional resistance, can by equipment torque conduction to pile body.
1) rig torsional performance checking computations
Choosing castinplace pile maximum gauge during calculating is 2000mm, and reinforcing bar configuration is specially: vertical muscle 40 Φ 25(HRB400), stirrup Φ 14@200(HRB335) stake check, then pile body opposing moment of torsion is:
-pile body moment of torsion
a 0 the area that-shear flow center line surrounds, gets π (2000/2)
2=3.14 × 10
6mm
2
a s -all vertical muscle sectional areas, table look-up to obtain 19636 mm
2
a sv single limb section area of-stirrup, table look-up to obtain 153.9 mm
2
f stk -vertical tendon exhaustion limit strength standard value, table look-up to obtain 540N/ mm
2
f stkv -stirrup ultimate strength standard value, table look-up to obtain 455N/ mm
