Description
Technical field
The invention belongs to geotechnical investigation technical field, be specifically related to a kind of without cable static cone penetration equipment and using method thereof.
Background technology
In geotechnical investigation technical field, static sounding is as a kind of in-situ testing method that directly can provide the comprehensive mechanical performance index of foundation soil, also be simultaneously that one possesses that layering is careful, layer position engineer geological prospecting method accurately, widely use in geotechnical investigation field and deeply trusted.
What current static cone penetration equipment generally adopted is have cable type static cone penetration equipment, the probe of sensor is housed to be at the uniform velocity pressed into underground by an inside, and because the soft or hard on various stratum, underground is different, the penetration resistance suffered by probe is naturally also different.This penetration resistance varied in size is transferred in the recorder of ground with voltage analog signal form by probe sensor, then converts data signal to by ground recorder and form final static sounding exploration results.Adopt this equipment, in the process of probe press-in underground, probe all the time be arranged on the multicore cable of recorder on the ground by nearly hundred meters and keep being connected, thering is provided for popping one's head in the small bridge of power supply, upwards transmission probe inner sensor Wheatstone bridge to press the analog signal of change downwards by this multicore cable therebetween, finally being completed digitlization and the data-storing function of this analog signal by recorder on the ground.Mainly there are following two large problems in which: first, which cannot the angle of inclination that certainly leads in process of press in of measuring probe, and along with this angle of slope of increase of depth of exploration often increasing, finally cause exploration achievement and actual conditions quite different; Secondly, because the whole multicore cables of nearly hundred meters are (the comprising the feeler lever be not yet pressed into) of running through all feeler levers continuously, therefore in probe process of press in, the work that arranges of sleeve pipe is hindered (except non-cable can press situation of change in base area, accomplish that quick-speed interruption is connected with safety again at diverse location), and then significantly reduce the depth of exploration of static sounding, finally greatly limit the scope of application of this exploitation method.Therefore, it is possible to measuring probe angle of inclination and be convenient to sleeve pipe arrange be one of direction of domestic and international geotechnical investigation circle primary study without cable static cone penetration equipment always.
