Low strain detector for foundation pile
Patent name: Method for reducing residual signal of shock elastic
wave to identify reflected wave signal
Patent No：ZL200910082851.4
Related patents
Instrument selection
The low-strain reflected wave method is to detect the integrity of the
pile body by analyzing the characteristics of the measured speed
response signal at the top of the pile, determine the position of the
pile body defect and the degree of influence, and determine the
embedment of the pile end and the type of integrity.
Test principle and
method
Active (with cap) foundation piles:
Sound foundation pile
Defective foundation pile
Excitation / receiving method
Reflected signal
Foundation piles during construction:
Test object: various types of foundation piles in civil and construction engineering (including
foundation piles in construction and active foundation piles);
Test content: New foundation pile (the head of the pile is exposed): length, integrity (degree
of defect and location range);
Foundation piles in service (with cap): length, integrity.
Test items
product description
Sichuan Shengtuo Testing Technology Co., Ltd. provides foundation pile low strain detector. This equipment is based on the low-strain reflected wave method, and is widely used in the integrity testing of column structures such as new foundation piles, active foundation piles, wharf pillars and high bridge piers in various civil and construction projects. It has the characteristics of high test efficiency and good reliability, and the use of stable and reliable imported components makes the detection accuracy of the length and integrity of the foundation piles guaranteed.
Achievements and
technical characteristics
Can test foundation piles under existing caps;
The test accuracy of the length and integrity of the foundation pile is greatly improved.
