Method and system for detecting plane position of power plant pile foundation

Abstract

The invention provides a method and system for detecting the plane position of a power plant pile foundation, and belongs to the field of power plant construction inspection. The method comprises the steps that first, at least two measuring control points are arranged around the power plant pile foundation needing to be detected, and two measuring control points A and B which are visible with each other are selected; second, the tangent line included angle alpha 1, the tangent line included angle alpha 2, the tangent line included angle beta 1 and the tangent line included angle beta 2 between the tangent lines of the measuring control points A and B and the left side and the right side of the power plant pile foundation and the segment connected with the measuring control points A and B are measured, and the central point included angle alpha and the central point included angle beta between the connecting lines of the measuring control points A and B and the center C of the power plant pile foundation and the segment connected with the measuring control points A and B are calculated according to the tangent line included angles; third, the coordinate (XA, YA) of the measuring control point A and the coordinate (XB, YB) of the measuring control point B are obtained; fourth, the coordinate (XC, YC) of the center C of the power plant pile foundation is calculated according to the coordinates of the measuring control points A and B and the central point included angles alpha and beta measured in the second step; fifth, the coordinate of the center C of the power plant pile foundation, obtained in the fourth step is compared with a coordinate provided in the design, and construction errors are obtained to be used as testing results to be output.

Description

technical field [0001] The invention relates to the technical field of power plant construction inspection, in particular to a method and system for detecting the plane position of a pile foundation of a power plant. Background technique [0002] With the development of science and technology in our country and the needs of engineering technology, more and more thermal power plants are being built, and the requirements for the construction accuracy of power plant pile foundations are also getting higher and higher. After the pile foundation construction is completed, the pile foundation of the power plant generally exists in the form of a cylinder, and the inspection and measurement cannot measure the center of the cylinder, so it is impossible to accurately check its accuracy. [0003] At present, there are two methods for detecting the plane position of pile foundations in general power plants: the first method, such as figure 1 As shown, set up the instrument on the cont...

AI Technical Summary

Problems solved by technology

This method is also not easy to find the center of the cylinder, and the distance from point B to the center of the pile foundation column has a large human error when measuring, which is time-consuming and error-prone

[0005] The accuracy of the above two detection methods is not high, and it is relatively error-prone

Often the detection accuracy is similar to that provided by the construction unit, and sometimes it is not as high as that provided by the construction unit, which cannot achieve the purpose of detection
