Description
Technical field
The utility model relates to a kind of foundation pile integrity detection device, particularly a kind of foundation pile integrity detection device that adopts sound wave transmission method.
Background technology
Building field extensively adopts piling strtucture at present, and the pile body integrity in the structure has very significant effects to the safety of buildings, and the sound wave transmission method ultrasound detection of cast-in-place concrete pile is a kind of method that extensively adopts in the current pile integrity detection.Existing pile quality inspection specifications; Comprise national sector standard, association criterion and region technical standard, following technical standard is representative: (1) People's Republic of China (PRC) industry standard " architecture foundation pile inspection specifications " (JGJ 106-2003); (2) China Engineering Construction Standardization Association's standard " ultrasonic method detection concrete defect " (CECS 21:2000).The essential characteristic of in-situ check and test method is in the above-mentioned technical manual: the cable line end in (1) each sound detecting pipe has one and a radial transducer is only arranged, and is single hole single transducer structure; (2) in the radial transducer lifting process, the constant spacing of being separated by is a measuring point, when the transducer monumented point arrives point position, gathers waveform and record sound parameter, and each measuring point elevation is accomplished the once test (put down and survey or tiltedly survey) of a survey line; Two sound detecting pipes are one and detect section; The elevation curve that parameter is obtained in an overall height journey detection (the flat survey or tiltedly survey) is that one dimension is tested; The i.e. variation of sound parameter is only relevant with elevation, and can not reflect the variation of the diverse location of same survey line (same elevation).If the once flat elevation position of surveying back discovery rejected region; And need further locate its horizontal level the time; Then need adopt one-sided oblique survey method to carry out repetition measurement one time, or bilateral intersects tiltedly to survey and carry out repetition measurement twice, tiltedly the angle measurement degree is decided by to launch the relative relief with receiving transducer.Defectives such as above-mentioned detection method exists an overall height journey of a section to promote test process can only accomplish the survey line test of a direction (put down and survey or tiltedly survey), and existence can't be to the space orientation of carrying out of rejected region, and the while testing efficiency is low.
The utility model content
The purpose of the utility model provides a kind of sound wave transmission method foundation pile integrity detection device; The overall height journey that solves a section of existing sound wave transmission method promotes the survey line test that test process can only be accomplished a direction, can't be to rejected region carry out space orientation and the low technical matters of testing efficiency.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of sound wave transmission method foundation pile integrity detection device; Comprise the one group of radial transducer that vertically is placed in the sound detecting pipe; Said radial transducer connects through cable; Every group of radial transducer is at least two, is provided with scalable line bag between the adjacent radial transducer, and said scalable connection bag and radial transducer are connected in series.
Said radial transducer is for transmitting and receiving interchangeable sexual type transducer.
Compared with prior art the utlity model has following characteristics and beneficial effect:
An overall height journey of a section promotes test process can accomplish the survey line test of a plurality of directions (flat survey and intersection are tiltedly surveyed) simultaneously; Saved and repeatedly to have adjusted the omnidistance again trouble that promotes test of transducer position in the conventional test methods, improved testing efficiency greatly.Workload with the dual transducers group is an example; Under the condition of same use multicast Ultrasound Instrument, for single section plane test, workload is 1/3 of a background information mode; For three section plane tests; Workload is 1/5 of a background information mode, and for four section plane tests, workload is 1/7 of a background information mode.
Through scalable line bag is set between adjacent two radial transducers; Conveniently adjusted spacing between two radial transducers up and down; And then regulate the angle of tiltedly surveying between survey line and the horizontal survey line, and it is controlled in the reasonable range, thereby helps the location of two-dimentional test result.
The said proving installation of the utility model, two sound detecting pipes are one and detect section, owing to accomplished flat survey simultaneously in each measuring point elevation position and intersected tiltedly survey; With the flat test result analysis-by-synthesis of surveying and intersecting oblique survey, not only can confirm the elevation position of quality Suspected Area, and can further locate its horizontal level; Thereby once, the overall height journey realizing accurate two-dimentional test (the flat survey and the tiltedly survey that intersects) in detecting; Avoided traditional single hole list transducer proving installation, need on the flat basis of surveying, carry out repetition measurement, ability position level position with tiltedly surveying; Simplified test procedure; More help simultaneously the space orientation of rejected region, if cooperate analysis software, the two-dimentional test result of many sections can also on-site real-time obtains the three-dimensional fix of defective.
The utility model can be widely used in foundation pile integrality sound wave transmission method and detect.
