Description
Technical field
The invention belongs to geotechnical engineering investigation technical field, and in particular to a kind of untethered static cone penetration equipment and its user
Method.
Background technology
In geotechnical engineering investigation technical field, static sounding can directly provide foundation soil synthesis mechanical property as one kind
The in-situ testing method of index, while and one kind possess the accurate engineer geological prospecting method in careful, the layer position of layering, in ground
Engineering exploration field is widely used and deep trusted.
At present static cone penetration equipment has generally used cable type static cone penetration equipment, will an inside equipped with sensing
, to be at the uniform velocity pressed into underground, as the soft or hard on the various stratum in underground is different, the suffered penetration resistance of probe is naturally also not for the probe of device
Equally.This penetration resistance of different sizes is transferred in the monitor of ground by probe sensor with voltage analog signal form,
Digital signal is converted into by ground monitor again and final static sounding exploration results are formed.Using the equipment, in probe press-in
During underground, probe keeps being connected by nearly hundred meters of multicore cable with the monitor for arranging on the ground all the time, therebetween by this
Multicore cable downwards for probe provides power supply, upwards the small bridge buckling of transmission probe inner sensor Wheatstone bridge simulation believe
Number, the digitized and data store function of this analogue signal is finally completed by the monitor of ground.Which is primarily present following
Two big problems：First, which cannot the angle of inclination that necessarily led in process of press in of measuring probe, and with exploration
The increase of the depth inclination angle is often increasing, ultimately results in exploration achievement quite different with practical situation；Secondly as near
Hundred meters of whole multicore cable is (feeler lever including being not yet pressed into) for being continuous through all feeler levers, therefore in probe process of press in
In hinder sleeve pipe setting work (except non-cable can base area pressure situation of change, diverse location accomplish quick-speed interruption and
Safety is reconnected), and then the depth of exploration of static sounding is significantly reduced, finally greatly limit the use model of the exploitation method
Enclose.Therefore it becomes possible to measure probe angle of inclination and be easy to sleeve pipe arrange untethered static cone penetration equipment be always domestic and international ground
One of direction of engineering investigation circle primary study.
At present, foreign countries have succeeded in developing case, and the NOVA series of such as Sweden GEOTECH AB companies is touched without cable static(al)
Spy system, automatic non-electric cable static sounding system of A.P.van den Berg Machinefabriek companies of Holland etc..
Or but this kind equipment is limited by signal transmission distance, it is impossible to realize that depth is surveyed；Cannot set with domestic general-purpose construction
It is standby to support the use and its price is extremely expensive.Therefore, this kind equipment is few at home at present uses.
Also there are part successfully research and development example, such as Application No. in the country：201110031820.3 it is disclosed《Cable-free type is quiet
Power cone penetrometer and data acquisition treatment method》, disclosed in Application No. 200910070579.8《The deep layer static(al) of Geotechnical Engineering
Feeler inspection method of testing》Deng.But its common shortcoming is can not to accomplish to carry out reality to test data in static sounding work progress
When monitor, particularly when probe runs into closely knit or firm hard formation, cause penetration resistance to exceed probe ability to bear, or ground bar
Part is complicated and lack of homogeneity, when causing probe to incline serious, due to finding in time and hole eventually, tend to cause to pop one's head in because
Overload and scrap or feeler lever amount of deflection is excessive and the major accident that fractures.Therefore, the kind equipment is not yet promoted at present at home
Popularization.
