Standard soil layer database is compared, and obtains the classification of such soil layer；It is subsequent according to frequency change point when tension weight churning and weight
The relative altitude of impact drop point obtains such the thickness of the layer, and records such the thickness of the layer.
Further, the standard soil layer include fill stratum, argillic horizon, powder soil horizon, mud, sandy soils, crushed stone soil layer,
The stratum of gravel boulder bed, karsts developing area rock stratum or cranny development.
Technical basis of the invention is as follows:
1, Punching Borehole Cast-in-place Concrete Pile is suitable for fill stratum, argillic horizon, powder soil horizon, mud, sandy soils, crushed stone soil layer, gravel cobble
The stratum of layer, karsts developing area rock stratum or cranny development.Since the soil layer that Punching Borehole Cast-in-place Concrete Pile is applicable in is limited, database ratio is established
It is easier to.
2, when same Punching Borehole Cast-in-place Concrete Pile stake machine operation, tension weight churning height remain unchanged, therefore do not have to consider due to
The variation of impact energy causes soil layer frequency to change.
3, for information collected during radio transmission, wireless digital sensor can be directly changed into number being measured
Amount output, has high measurement accuracy and resolution ratio, stability is good, strong antijamming capability, ensure that the true and reliable of data.
4, the compactness variation of areal soil layer is little, therefore similar soil layer hits generated frequency amplitude of variation very
It is small.
