Coaxial positioning device capable of simultaneously measuring azimuth angles and inclination angle of tubular pile

Abstract

According to the coaxial positioning device capable of simultaneously measuring the azimuth angles and the inclination angle of a tubular pile, the outer contour of the positioning device can be expanded and adjusted, and the positioning device can be suitable for pipe piles with different inner diameters and can smoothly pass through the uneven condition of the inner wall of the pipe pile within 5 mm; the inclination angle and the azimuth angle of the tubular pile can be measured within the depth range from at least one half of the height of the inclinometer at the bottom of the tubular pile to one half of the depth of the inclinometer at the top of the tubular pile, so that the measurement precision is improved; the problems that after field tubular pile construction is completed, the inclination measuring process is tedious (an existing device needs to pre-embed measuring parts before piling), coaxiality of inclinometer and tubular pile is poor (an inclinometer support is difficult to center), the same testing instrument cannot be used for tubular piles with different diameters, and full-depth measurement of tubular pile is difficult (the flatness of inner wall of tubular pile and the section of pile splicing position), and the inclination angle and the azimuth angle of the tubular pile cannot be measured simultaneously are solved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering construction detection, in particular to a coaxial positioning device for detecting the inclination angle of pipe piles which can simultaneously measure the azimuth angle. Background technique [0002] In piling construction, the phenomenon of pipe piles tilting occurs from time to time. The pile body tilts too much, the foundation pile is eccentrically compressed, and the bearing capacity is reduced. The harm is obvious. Therefore, the relevant codes put forward clear requirements on the sag of foundation piles. For example, in the "National Standard for Construction Quality Acceptance of Building Foundation Engineering" (GB50202-2002), it is clearly stipulated that the allowable deviation of the verticality of foundation piles shall not exceed 1% (approximately 0.57°), while "Technical Specifications for Building Foundation Pile Inspection" (JGJ 106-2003), "Technical Regulations fo...
