Embodiment:
As shown in figs. 1-7, the method and step of Rock And Soil detection of grouting effects are as follows:
S1: laying detection duct 4 within the scope of the center in Rock And Soil slip casting region 3 and prediction diffusion zone respectively, wherein
Predict that multiple groups are laid within the scope of diffusion zone detects duct 4, every group of detection duct 4 is three and is center structure with slip casting region 3
It is laid out at triangle, and distance of the multiple groups detection duct 4 apart from 3 center of slip casting region successively increases, the detection duct 4 is with PVC
Casing fills water as retaining wall and in hole；
S2: spark source 5 is placed in any detection duct 4, and string 1 is placed in other any detection ducts 4
And wave detector is coupled one by one with the inner wall in detection duct 4 by multiple positioning mechanisms 14；
S3: spark source 5 and string 1 are connect with testing and analysis system 6, the testing and analysis system 6 includes
High-precision velocity of wave Acquisition Instrument 63 and computer 65, the string 1 pass through the second cable 61 and high-precision velocity of wave Acquisition Instrument 63
Signal connection, spark source 5 are connect also by third cable 62 with 63 signal of high-precision velocity of wave Acquisition Instrument, the high-precision wave
Fast Acquisition Instrument 63 is connect by the 4th cable 64 with 65 signal of computer；
S4: respectively before and after slip casting, elastic wave is excited by spark source 5, and by the collected signal of string 1
It is sent to high-precision velocity of wave Acquisition Instrument 63, the high-precision velocity of wave Acquisition Instrument 63 transmits a signal to the computer 65 again, meter
Calculation machine 65 forms two-dimensional CT image by inversion algorithm；
S5: by the two-dimensional CT image of Rock And Soil before and after comparison slip casting, determine slip casting region 3 and slip casting effect.
Wherein, in the step S1, using the center of the Rock And Soil injected hole 2 of multiple rounded arrangements as slip casting region 3
Center, drill in the range of prediffusion region, lay detection duct 4, detect the distance between duct 4 and slip casting region 3
It may gradually increase, such as 1.5m, 2.0m, 3.0m, it is preferred that hole depth will be beyond low absolute altitude 1.0m of stake or so, and guarantees certain
Verticality, and adding PVC casing prevents detection duct 4 from collapsing and water storage, while to clearing up in drilling, to guarantee to examine
Wave device string 1 and spark source 5 can provide precondition down toward the required depth reached for detection, wherein for save the cost
With raising detection efficiency, the injected hole 2 also is used as detection duct 4；
In the step S2, spark source 5 is put into any detection duct 4, and guarantees that spark source 5 can examined
It freely up and down moves, string 1 is put into other any detection ducts 4, wherein between pick-up unit in gaging hole road 4
Vertical interval need to meet design requirement, and the spark source 5 and string 1 are set to the water level in detection hole road 4
Hereinafter, the spark source 5 can excite elastic wave, and sound wave therein is received by string 1, is cut so that measurement is corresponding
Slip casting effect in face, for the quality of reception for guaranteeing sound wave, multiple pick-up units of the string 1 pass through its positioning

Fast Acquisition Instrument 63 is picked up by third cable 62 and records the collected acoustic signals of string 1, and then high-precision velocity of wave is adopted
Collection instrument 63 passes to the acoustic signals being recorded on computer 65 by the 4th cable 64；
In the step S4 and S5, the computer 65 is according to collected acoustic signals, when first break picking wave is walked, carries out
Wave velocity C T tomography finds out color exception area by Rock And Soil CT imaging contrast around pile foundation before and after slip casting, when discovery is being infused
Slurry front and back region and surrounding Rock And Soil color change are obvious and when having obvious boundary, determine that the color change region is slip casting
Area, testing result are intuitive, clear.
In addition, the method for coupling pick-up unit one by one with the inner wall in detection duct 4 in the step S2, including it is following
Step:
S11: the fixture block of the card column 152 of multiple pick-up units is stuck in corresponding 151 lower part of stopper, by spring
146 compressions, make support arm 142 to contract, then send string 1 into detection duct 4；
S12: the string 1 is sent to predetermined altitude, and connecting rope 11 is fixed, and upward rope, is successively made every
The fixture block of the card column 152 of a pick-up unit is disengaged with stopper 151, and spring 146 restores nature and drives branch
Brace 142 trails, and pick-up unit is coupled with the inner wall in detection duct 4 one by one；
S13: directly string 1 is taken out from detection duct 4 by connecting rope 11 after detection.
In the above-mentioned technical solutions, in the step S13, after detection, during string 1 is pulled up,
The support arm 142 is automatically to contract, it may be convenient to take out string 1 from detection duct 4, and wave detector is not
It can directly be touched with the inner wall for detecting duct 4, avoid the structure of damage wave detector.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
