Description
Technical field
This utility model relates to a kind of side hole transmitted wave method and determines detection foundation pile device for detecting length, belongs to building detection skill
Art 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. CN103953076A disclose a kind of civil engineering pile foundation engineering quality testing field based on
Depth determination method at the bottom of the existing engineering pile stake of side hole transmitted wave bathmometry, by detection in inspecting hole after stake sidetracking inspecting hole,
And generate time depth signal graph according to different depth signal along the degree of depth, by determining flex point in time depth signal graph,
And to the flex point degree of depth by the degree of depth at the bottom of obtaining after flex point adjusting for depth formula correction.This utility model not by superstructure to ripple
The impact of shape, easy to detect, determine that corner position is simple and directly perceived.Stake is determined based on two line intersection points with existing side hole transmitted wave method
