Description
Technical field
This utility model relates to a kind of based on parallel seismic wave method detection foundation pile device for detecting length, belongs to building detection technique
Field.
Background technology
Along with the fast development of economic construction, high buildings and large mansions continue to bring out, and pile foundation engineering obtains and develops on an unprecedented scale, pile foundation
It it is the base form being most widely used at present.Owing to pile foundation engineering construction has highly disguised, find that quality problems are relative
More difficult, industry is much owing to the quality problems of pile foundation engineering cause with the quality accident in civil buildings.
Test Technology of Pile Foundation has obtained significant progress in recent years, and coherent detection standard, specification are in succession promulgated and implement, right
Ensure that construction quality serves good effect.But the most conventional Test Technology of Pile Foundation, such as static load test, core drilling method, height
Strain Method, low strain dynamic method and sound wave transmission method etc., be both needed to directly contact Under Pile top, thus its use occasion receive certain
Limit, be normally only applicable to before top-out structure not yet constructs.
But, engineering construction is frequently encountered the foundation pile length under existing buildings or structures or integrity are suspected
And produce contradiction and disputes, or owing to existing building is of the remote past, when subsequent adaptation engineering lacks stake capsule information such as long grade, with
And owing to there occurs that the other reasons such as surface subsidence, earthquake causes the situations such as later stage destruction to pile foundation and needs to build existing
Pile foundation under building detects, but owing to now top-out structure has existed, it is impossible to directly contact stake top, thus routine
Pile foundation inspection method is helpless.
Owing under current domestic existing buildings or structures, the systematic study of Test Technology of Pile Foundation still belongs to blank, therefore research one
Pile detection new technique under the existing buildings or structures that kind strong adaptability, restricted condition are few, to objectively and accurately evaluating work
Cheng Zhiliang, the contradiction and disputes solved in engineering construction and improve existing buildings or structures performance rating or dilapidated house secure authentication refers to
Mark systems etc., have bigger realistic meaning, also will promote the further development of architecture foundation pile detection technique.
As Application No. CN101570974A discloses one side hole transmitted wave method detection existing building foundation pile matter
The method of amount, it is by burying the pvc pipe being parallel to foundation pile by existing building foundation pile underground, and utilizing works seismic detector is along PVC
Pipe depth direction tests the seismic wave come through foundation pile transmission, according to first arrival time and the amplitude of seismic wave received by cymoscope
The method judging foundation pile length and integrity.The principle of this method of testing is: seismic wave is the biggest in the spread speed of foundation pile
In at soil around pile, and attenuation quotient is less than soil around pile, and when cymoscope is away from foundation pile bottom, the seismic wave received is in soil
The distance propagated increases, and prolongs and accelerate the decay of amplitude, in like manner in the position of pile defect also after necessarily strengthening first arrival time
There will be increasing suddenly and the unexpected decay of amplitude of first arrival time, therefore can be by seismic wave wave train first arrival time and amplitude
Comprehensive analysis, judges foundation pile length and integrity.
And for example Application No. CN103255785A disclose a kind of use single tube normal beam technique carry out quality inspection of the piles and
The technology of geology detecting, it is characterised in that tap on foundation pile end face and produce the compressional wave along pile body travel downward, by sounding
The time of advent detecting compressional wave in pipe is poor, and longitudinal wave velocity and the stake of Accurate Determining foundation pile are long, it is determined that pile body concrete quality；Neighbour
The pipeline of stake or geotechnical boring are surveyed compressional wave downward and poor from the time of advent that Pile side soil is propagated along being tapped pile body, measure base
Pile length, pile quality and reaming degree；And the velocity of wave of geology soil layer can be measured, judge the situation of stake week geology soil layer, analyze
Foundation pile enters rock situation.This utility model can be joined outward or embed signal in the detection equipment Foundations such as existing low strain dynamic, ultrasound wave
Processor, it is achieved the lossless inspection of pile foundation that a kind of new pile quality Non-Destructive Testing and the technology of geology detecting are also economic, ready-made
Survey auxiliary verification method, accuracy and service level that pile foundation quality judges can be significantly improved.
Above-mentioned two documents is the immediate prior art of pre-the application, but its problem having is as follows: preliminary examination
Surveying cumbersome, need punching, note clear water, operation is comparatively laborious.
