Description

Parallel seismic wave method determines the detection means and its detection method of foundation pile length
Technical field
The present invention relates to one kind based on parallel seismic wave method detection foundation pile device for detecting length, belong to building detection technique neck Domain.
Background technology
With the fast development of economic construction, high buildings and large mansions are continued to bring out, and pile foundation engineering is developed on an unprecedented scale, pile foundation It is the base form being most widely used at present.Because pile foundation engineering construction has height disguised, it is found that quality problems are relative More difficult, industry is due to much caused by the quality problems of pile foundation engineering 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 promulgated and implemented in succession, right Ensure that construction quality serves good effect.But conventional Test Technology of Pile Foundation at present, 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 foundation pile stake top, thus its use occasion receive it is certain Limitation, before normally only not yet being constructed suitable for top-out structure.
The foundation pile length under existing buildings or structures or integrality are suspected however, being frequently encountered in engineering construction And contradiction and disputes are produced, and or because existing building is of the remote past, when lacking that stake is long to wait capsule information in subsequent adaptation engineering, with And need to build to existing because of situations such as causing pile foundation there occurs other reasonses such as surface subsidence, earthquakes later stage destruction Pile foundation under building is detected, but because now top-out structure has been present, and can not directly contact stake top, thus conventional Pile foundation inspection method is helpless.
Because the system research of Test Technology of Pile Foundation under current domestic existing buildings or structures still belongs to blank, therefore study one Kind strong adaptability, the pile detection new technology being restricted under the few existing buildings or structures of condition, to objectively and accurately evaluating work Cheng Zhiliang, solve the contradiction and disputes in engineering construction and improve existing buildings or structures performance rating or dilapidated house secure authentication refers to Mark system etc., there is larger realistic meaning, will also promote the further development of architecture foundation pile detection technique.
As an Application No. CN101570974A discloses one kind side hole transmitted wave method detection existing building foundation pile matter The method of amount, it is that utilizing works seismic detector is along PVC by burying the pvc pipe parallel to foundation pile by existing building foundation pile Pipe depth direction is tested through foundation pile transmitted through the seismic wave come, the first arrival time and amplitude of seismic wave according to received by wave detector To judge the method for foundation pile length and integrality.The principle of the method for testing is:Seismic wave is much big in the spread speed of foundation pile In in soil around pile, and attenuation coefficient is less than soil around pile, and when wave detector is away from foundation pile bottom, the seismic wave received is in soil The distance increase of propagation, prolongs after necessarily increasing first arrival time and accelerates the decay of amplitude, similarly in the position of pile defect The unexpected increase of first arrival time and the unexpected decay of amplitude occurs, therefore can be by seismic wave wave train first arrival time and amplitude Comprehensive analysis, judge foundation pile length and integrality.
And for example an Application No. CN103255785A disclose it is a kind of using single tube normal beam technique carry out quality inspection of the piles and The technology of geology detecting, it is characterised in that the compressional wave for producing and being propagated downwards along pile body is tapped on foundation pile top surface, by sounding The reaching time-difference of compressional wave is detected in pipe, the longitudinal wave velocity of Accurate Determining foundation pile and stake are long, judge pile body concrete quality；In neighbour Compressional wave is surveyed in the pipeline or geotechnical boring of stake along the reaching time-difference for being tapped pile body downwards and being propagated from Pile side soil, determines 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.The present invention can outside match somebody with somebody on the basis of the detection devices such as existing low strain dynamic, ultrasonic wave or be embedded in signal transacting Device, realizes the technology of a kind of new pile quality Non-Destructive Testing and geology detecting, and economic, ready-made nondestructive quality detection of pile foundation is auxiliary Verification method is helped, the accuracy and service level of pile foundation quality judgement can be significantly improved.
