Tubular pile inclination measuring device and using method thereof

Abstract

The invention discloses a tubular pile inclination measuring device comprising at least one support, wherein a through hole is formed in the support; an inclinometer is arranged inside the through hole; the support comprises two outer support rods which are arranged horizontally and are perpendicular to each other; a fixed inner support rod is inserted in one end of each outer support rod and a retractable inner support rod is inserted in the other end of each outer support rod; the outer ends of the fixed inner support rods and the retractable inner support rods are respectively provided with a roller; and an elastic piece is arranged between each outer support rod and the corresponding retractable inner support rod. When the tubular pile inclination measuring device is used in measurement, the elastic pieces are compressed, so that the device can be kept in parallel to the inner wall of a tubular pile so as to slide into the tubular pile. The tubular pile inclination measuring device is capable of accurately measuring the inclination of a tubular pile body in a manner of neither damaging the tubular pile body nor excavating a soil body around the tubular pile. Compared with a former line hammer method for measuring the inclination of the tubular pile, a measuring method using the device has the advantages that the accuracy of measuring the inclination of the tubular pile is improved greatly, and the pile body deformation at a deep part of the tubular pile, which can not be measured by the conventional line hammer method, can be measured by the device.

Description

technical field [0001] The invention relates to the technical field of building construction measurement, in particular to a pipe pile inclination measuring device and a using method. Background technique [0002] The verticality of the pipe pile after it is driven into the soil is an important quality index of the pile. If the verticality deviation is greater than the design requirements, it needs to be corrected, or even treated as a waste pile. However, the detection of the inclination of pipe piles is a difficult point in construction. In the prior art, the distance between the vertical line and the inner wall of the pipe pile is generally measured with a hanging hammer in the hole of the pipe pile, and finally the inclination of the pipe pile is calculated. The shortcoming of this detection method is: the precision of detection is relatively low, and can only detect the topmost place of pipe pile, and can't measure to the deeper place of pipe pile.

AI Technical Summary

Problems solved by technology

The disadvantage of this detection method is that the detection accuracy is relatively low, and it can only detect the topmost point of the pipe pile, but cannot measure the deeper part of the pipe pile.

However, this kind of inclinometer needs to detect the inclination of the inner hole, and several points need to be done in the measurement: first, the probe of the inclinometer must be kept parallel to the depth direction of the measured hole in the measured hole, and the probe and the depth direction of the measured hole cannot be caused by gravity. The depth direction of the measured hole is not parallel; second, the inclinometer probe must be in the center position at all times in the measured hole, and the attitude of the probe in the measured hole cannot be twisted or deflected.
