Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:
A kind of anti-falling type foundation pile low strain dynamic dynamic measuring instrument, including foundation pile movable measurement instrument 3, it is connected to 3 top of foundation pile movable measurement instrument
On connector 4,3 surface of foundation pile movable measurement instrument adjusting key 1, be embedded in display screen 2 that foundation pile movable measurement instrument 3 is equipped with and installation
Mainboard 5 inside foundation pile movable measurement instrument 3；It is one-dimensional that low strain integrity testing principle commonly known in the art is that reflective wave method is built upon
On the basis of wave theory, stake is assumed to be one-dimensional elastic continuous lever, vertical exciting is carried out at the top of pile body and generates elastic wave, elasticity
Wave is propagated downwards along pile body, when there are the interface of notable difference (such as stake bottom, broken pile and serious isolations) or pile body to cut for pile body
Area change (such as undergauge or expanding) position, wave impedance will change, and back wave be generated, by the sensor for being mounted on stake top
Reflection signal is received, received reflection signal is amplified, is filtered and data processing, can be identified from pile body different parts
Reflective information.Using wave in pile body propagate when longitudinal wave velocity, the long corresponding relationship between reflection interval of stake, by anti-
The analytical calculation for penetrating information judges the integrality of pile concrete and checks the physical length of stake according to average velocity of wave, determines stake
Body defect level and position.
The design is that the inside mainboard 5 by the foundation pile movable measurement instrument 3 of model not of the same race is protected, such as: the prior art
In universal common HC-DT50 model, HC-DT51 model, the dynamic tester of RSM-PDT (B) model etc., sent as an envoy to due to often outer
