Abstract
The invention relates to novel penetration sounding device and method for engineering investigation. The novel penetration sounding device comprises a static pressure unit, a rod clamping unit, a ground anchor, a touch probe, an air compressor, an air supply hose, a pneumatic hammer, an electric measuring touch probe, a depth acquisition unit and a penetration sounding recorder. The pneumatic hammer is directly arranged at the upper end of the electric measuring touch probe and can directly hammer the electric measuring touch probe in a hole. The electric measuring touch probe collects penetration resistance data of soil for storing the data or sending the data to the penetration sounding recorder. The novel penetration sounding device and method has the advantages of being good in penetration sounding hole perpendicularity, large in penetration depth, applicable to penetration sounding of general soil and dense sandy soil and wide in application range.
Description
Technical field
The present invention relates to builing industry, a kind of novel sounding device for engineering investigation and detection method.
Background technology
Extensively adopt static sounding in domestic and international geotechnical investigation, static cone penetration equipment comprises: static(al) compression system, anchoring system and measurement system.By static(al) water booster system by sounding rod by electric contact probe injection soil, electric contact probe record soil penetration resistance, penetration resistance can accurately determine soil physico-mechanical properties, precision is high.
At present, static cone penetration equipment is only afterburning on earth's surface, and sounding rod is flexible, and injection frictional resistance is large, and depth of penetration is little, and can not pass closely knit sand, general depth of penetration is 15 ~ 40 meters, can not meet highrise building, the requirement of high-speed railway exploration 60 ~ 100 meters of degree of depth.
Summary of the invention
The object of the invention is to develop a kind of depth of penetration large, the continuous reliable novel sounding device of test data and detection method.
A kind of novel sounding device of the present invention and detection method be by the following technical solutions: in static cone penetration equipment, increase Pneumatic impact system.
A kind of novel sounding device of the present invention and detection method comprise: static(al) compression system, anchoring system, Pneumatic impact system and measurement system.Static(al) compression system is made up of static(al) water booster system, jamming rod device and sounding rod etc.; Anchoring system by conduct oneself with dignity and earth anchor form; Pneumatic impact system is made up of air compressor machine, sebific duct of supplying gas, air hammer; Measurement system is made up of electric contact probe, depth collecting device and feeler inspection recorder, a kind of novel sounding device of the present invention and detection method, it is characterized in that: the combination of static(al) compression system and Pneumatic impact system, air hammer is directly placed in electric contact probe upper end, air hammer is direct hammering electric contact probe in feeler inspection hole, electric contact probe adopts without cable electric contact probe, and electrometric sensor, memory or emitter are housed therein.
Beneficial effect of the present invention and advantage are: air hammer is direct hammering electric contact probe in feeler inspection hole, and have vertically-guided effect, feeler inspection hole perpendicularity is good, and depth of penetration is large, can be used for the feeler inspection of general soil layer and closely knit sand, applied widely.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of novel sounding device of the present invention and detection method structural representation.
Number in the figure: 1 static(al) water booster system, 2 jamming rod devices, 3 earth anchors, 4 sounding rods, 5 air compressor machines, 6 supply gas sebific duct, 7 air hammers, 8 electric contact probes, 9 depth collecting devices, 10 feeler inspection recorders.
Detailed description of the invention
As shown in Figure 1, a kind of novel sounding device of the present invention and detection method, mainly comprise static(al) water booster system 1, jamming rod device 2, earth anchor 3, sounding rod 4, air compressor machine 5, sebific duct 6 of supplying gas, air hammer 7, electric contact probe 8, depth collecting device 9 and feeler inspection recorder 10.
Below in conjunction with drawings and Examples, a kind of novel sounding device of the present invention and detection method are added a supplementary explanation.
Static(al) water booster system 1 and corollary equipment apply vertical static(al) on ground continuously to sounding rod 4 and electric contact probe 8, air compressor machine 5 produces compressed air by sebific duct 6 of supplying gas, input air hammer 7, be placed in the air hammer 7 of electric contact probe 8 upper end under compressed air effect, piston reciprocates in its body, produce power vertically downward, constantly directly hammering electric contact probe 8 makes it continuous injection, under the acting in conjunction of making a concerted effort of above-mentioned static(al) and power, electric contact probe 8 extrudes surrounding soil pore-forming in soil layer, air hammer 7 hammering electric contact probe vertically downward in hole, there is vertically-guided effect, make sounding rod verticality good, not flexible, increase feeler inspection depth of penetration.
The penetration resistance data of the electrometric sensor real-time collection and continual collection soil in electric contact probe 8, store data in the storage device in electric contact probe 8 or transmit data to feeler inspection recorder 10, thus realize the test of quiet dynamic sounding.
