Technical Field

The utility model relates to a foundation engineering field, in particular to measure positioner.

Background

In the field of engineering detection, the influence of two factors needs to be considered when the integrity of the pile body is detected by adopting a low-strain method. Firstly, the influence of size reduction effect needs to be considered, and theoretical research shows that: for a solid pile, when the distance between the mounting point of the sensor and the center of the pile is about 2/3 of the radius of the pile, the influence of the size effect on the signal acquired by the sensor is small; for the hollow pile, the mounting point of the sensor is preferably 1/2 of the hollow pile. In order to reduce signal interference as much as possible, the installation position of the sensor needs to be accurately located.

Secondly, because the difference of the signals measured by different excitation points and detection points is mainly strengthened along with the increase of the irregularity degree of the pile diameter or the section size of the upper part of the pile, the regularity of the signals of each pile under the similar conditions in the same field is found out as much as possible, and the signals of a plurality of piles need to be rapidly acquired.

In summary, there is a need for a positioning device that quickly and accurately measures and positions the mounting point of a sensor on a pile body.
