It according to the electronic piling specification of arm's length standard, successively drives piles according to normal working procedure, records the time of piling, it is real
Test data record deposit table 2.It is learnt from the analysis of experimental data of table 2, A type pile driving construction difficulty is larger, and Type B pile driving construction effect is most
It is good, strongly weathered sand-rock can be squeezed into, after reversely exiting, can be clearly seen that the rock white powder smashed from helical blade appearance
End, the ground pile that do not squeeze into, after extraction, helical blade it is subsidiary be all soil, there is no rock white powder.C-type stake is just
When starting piling, soil is than relatively soft, and early period, Piling speed was very fast, and into after decomposed rock, original place is turn-taked, and cannot continue to beat
Enter.The stake of D type and E type stake effect are general, can squeeze into, but the process squeezed into is difficult.F type stake effect is preferable, drives piles three times, and two
It is secondary quickly to squeeze into.
It is found by field experiment, Type B spiral ground pile is best in the construction effect of strongly weathered sand-rock, and F type takes second place, c-type, D
Type, E type, A type are successively deteriorated.
It will be appreciated that the embodiments of the present invention while there has been shown and described that, for the common skill of this field
For art personnel, it is possible to understand that can be carried out to these embodiments in the case where not departing from the principles of the present invention and spirit
