Abstract
The present invention discloses a kind of novel freezing efficiency detection device.It is detected based on seismic wave theoretical, heavy tamping ground is driven to generate seismic wave by calutron, the characteristic being had differences using the elastic wave impedance of frozen soil in stratum and non-frozen soil, the seismic signal received according to geophone, and the relative position of geophone and mobile controlled source, the spreading range for judging the frost wall that frozen construction is formed, determines freezing efficiency.Present invention is mainly applied to freezing efficiency field of detecting in inclined shaft freezing method sinking shaft work progress.
Description
Technical field:
The present invention is a kind of novel freezing efficiency detection device, freezes to imitate suitable for inclined shaft freezing method sinking shaft work progress
Fruit field of detecting.
Background technology:
When using freeze-wellboring technology construction inclined shaft, to determine the range of frost wall, freezing efficiency is detected, is usually existed
Freezing hole is disposed about thermometer hole, and the temperature of the underground soil body is detected by thermometer hole, to judge the spreading range of frost wall.But
It since the tilt length of inclined shaft is longer, needs the thermometer hole arranged more, increases drilling construction cost.Existing patent disclosure
A kind of detection method of freezing efficiency is based on electrical survey (-ing) principle, is freezing the soil body using apparent conductivity and do not freezing the soil body
Electrical property difference detects freezing efficiency.But it needs, in big merging drill rod on the ground, then detection electrode to be installed on drill rod, and utilize
Electrode is together in series by conducting wire one by one.Equipment needed for this method is more, process takes, and as frozen construction extends forward, needs
Repeatedly installation, dismounting drill rod and electrode, are unfavorable for efficient, the quick detection of freezing efficiency.And highdensity electrode arrangement can be made
There is bulk effect at result of detection, easy to produce pseudomorphism, and the electrode arrangement of low-density can make the reduction of result of detection precision.
Invention content:
To overcome existing freezing efficiency detection method in actual application, with the progress of frozen construction, need repeatedly
Installation, dismounting drill rod and electrode, influence the problem of freezing efficiency efficiently detects, and the present invention utilizes mobile controlled source and earthquake
Wave detector determines the position at frost wall edge, detects freezing efficiency.By mobile controlled source in inclines overhead surface
Excitation generates Artificial Seismic Wave, while arrangement geophone receives reflection seismic waves on the ground, using frozen soil in stratum and
The characteristic that the elastic wave impedance of non-frozen soil has differences, the seismic signal received according to geophone and earthquake inspection
The relative position of wave device and mobile controlled source judges that the spreading range for the frost wall that frozen construction is formed, determination are freezed to imitate
Fruit.
The present invention solves the problems, such as that existing freezing efficiency detection device and method exist the technical scheme adopted is that mobile
Formula controlled source is non-explosive source, drives heavy tamping ground to generate seismic wave by calutron, calutron passes through spiral shell
Bolt is fixed on circle ring rack, it is made to be in the center of circle ring rack;Circle ring rack main body is circular ring structure, and is leaned outward
Tiltedly 3 rack legs of setting, rack leg are mounted below universal wheel, 4 threaded holes are arranged on annulus, are used for Motionless electromagnetic device;
Weight is the larger cuboid weight of quality, is connect with calutron by metal link rod, and weight passes through circle ring rack, in electromagnetism
The lower section of device.When mobile controlled source work, calutron attracts connecting rod to rise, and drives weight lifting, closes electromagnetism and inhales
After drawing, weight is fallen under the effect of gravity, is formed and is impacted to ground, generates seismic wave in the earth formation.It is required according to detection accuracy,
Along vertical bore axis in several geophones of ground configuration, receive by frozen soil in stratum and the earthquake after the reflection of non-frozen soil
Wave analyzes the position relationship between the seismic signal and focus and geophone of each geophone, determines frost wall
The position at edge, to realize the purpose of detection freezing efficiency.When frozen construction promotes axially forward along pit shaft, Forward earthquake inspection
Wave device and mobile controlled source detect freezing efficiency, determine the spreading range of frost wall again to new frozen region.
The invention has the advantages that novel freezing efficiency detection device is based on seismic wave detection theory, examined by earthquake
Wave device is received to be excited by mobile controlled source and be generated, and through frozen soil in stratum and the seismic wave after the reflection of non-frozen soil, judges to freeze
The position for tying wall avoids frequently installation, dismounting drill rod and electrode.
