In weight.
A kind of method of work of Punching Borehole Cast-in-place Concrete Pile pile foundation Seines types automatic discrimination system, comprises the following steps：
A, frequency collection device is connected with wireless numerical value sensor, and Punching Borehole Cast-in-place Concrete Pile stake is sealed in epoxy resin
In machine weight；
If B, existing standard soil layer database in computer, goes to step D；Otherwise C is gone to step；
C, before the work of Punching Borehole Cast-in-place Concrete Pile stake machine, tension weight churning standard setting-out soil layer, frequency collection device collection soil layer frequency are utilized
The data gathered are simultaneously sent to computer by rate by wireless digital sensor, after computer receiving data and processing data,
Formation standard soil layer database is simultaneously stored in computer；
D, when Punching Borehole Cast-in-place Concrete Pile stake machine works, tension weight churning soil layer, frequency collection device gathers soil layer frequency and by wireless
The data gathered are sent to computer by number sensors, after computer receiving data and processing data, by the data of soil layer with
Standard soil layer database is compared, and draws the classification of such soil layer；It is follow-up according to frequency change point during tension weight churning and weight
The relative altitude of impact drop point draws 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.
The technical basis of the present invention is as follows：
1st, Punching Borehole Cast-in-place Concrete Pile is applied to 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.Because the soil layer that Punching Borehole Cast-in-place Concrete Pile is applicable is limited, therefore establish database ratio
It is easier to.
2nd, during same Punching Borehole Cast-in-place Concrete Pile stake machine operation, its tension weight churning highly keeps constant, thus without consider due to
The change of impact energy causes soil layer frequency to change.
3rd, for the information gathered during radio transmission, wireless digital sensor can be directly changed into numeral 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.
4th, the compactness change of areal soil layer is little, therefore frequency amplitude of variation caused by the shock of similar soil layer is very
It is small.
It is an advantage of the invention that it will be apparent that it is mainly manifested in：
1st, the present invention can judge the classification of soil layer with fast accurate.According to the mark in live punching frequency and computer
Quasi- soil layer database contrast, you can accurately draw the classification of actual soil layer, efficiently solve workmen's subjectivity at this stage and estimate
The problem of can not obtaining Seines types exactly when counting Seines types, while detail design or change most preliminary design can be checked
Meter, construction quality is improved, reduce engineering cost.
2nd, the present invention can precisely measure operation the thickness of the layer.When Seines types change, tension weight churning soil layer
Frequency can occur substantially to fluctuate, the relative mistake of recording frequency change point and follow-up tension weight churning drop point depth is to act on this
