Domain.
Background technique
With the rapid development of economic construction, high buildings and large mansions continue 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.Since pile foundation engineering construction has height concealment, discovery quality problems are opposite
More difficult, industry is much due to 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
It is good to guarantee that construction quality plays the role of.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. are both needed to directly contact foundation pile stake top, thus its use occasion receive it is certain
Limitation is generally only applicable to before top-out structure not yet constructs.
However, be frequently encountered in engineering construction under existing buildings or structures foundation pile length or integrality suspect
And contradiction and disputes are generated, or since existing building is of the remote past, when lacking the long equal capsule information of stake in subsequent adaptation engineering, with
And the later period caused to pile foundation and destroys and needs to build to existing because of situations such as having occurred the other reasons such as surface subsidence, earthquake
Pile foundation under building is detected, but since top-out structure at this time has existed, and can not directly contact stake top, thus conventional
