Problems solved by technology

[0002] There are many equipment and pipelines in nuclear power plants, and there are many pipelines reserved for walls and floors. During the construction process, inspections are frequent and measurements are many. The walls are high and the construction site conditions are poor. Inspections are inconvenient, safety performance is not easy to guarantee, and inspections take a long time. It is not conducive to the optimization of the construction period and cannot ensure the quality of work

Embodiment Construction

[0026] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] A method for checking the position of a pipeline based on HDS7000 three-dimensional scanner technology provided in this embodiment, such as figure 1 and figure 2 As shown, the origin of the construction coordinate system is the intersection of the ground and the two side walls, the X-axis is the intersection line parallel to the ground and the wall, the Y-axis is vertical to AX on the ground, and the H-axis is upward, which conforms to the right-handed coordinate system. The plane formed by the A-axis and the B-axis of the instrument coordinate system is parallel to the ground and also conforms to the right-handed coordinate system, including the following steps:

[0028] The first step, marking - marking the reference point of the wall embedded parts, three points form a plane, and the positions are evenly distributed;

[0029] The s...

Abstract

The invention relates to a pipeline position detection method based on three-dimensional scanning. The method comprises the following steps of selecting a plurality of control reference points on a wall, simultaneously setting the target markers, measuring the coordinates of the control reference points in a construction coordinate system, scanning the position of a pipeline, scanning a referencepoint target at the same time, converting the scanning data into the construction coordinate system, intercepting the scanning data of the pipeline, sorting the pipeline data according to a wall body,selecting a section of section data according to requirements, dividing into the pipe inner side data and the pipe outer side data according to another column of data, and respectively calculating the pipeline center coordinates according to assumed theoretical radiuses to obtain the pipeline center and radius actual values. According to the invention, an accurate detection result can be obtained, the problem of inspection of the pipeline position in nuclear power construction, especially when the pipeline amount is very large, is solved, the inspection safety of the pipeline at high altitudeis improved, the detection is flexible, the measurement is convenient, and the quality control requirement of on-site construction can be met.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant construction, in particular to a method for detecting the position of a pipeline based on three-dimensional scanning. Background technique [0002] There are many equipment and pipelines in nuclear power plants, and there are many pipelines reserved for walls and floors. During the construction process, inspections are frequent and measurements are many. The walls are high and the construction site conditions are poor. Inspections are inconvenient, safety performance is not easy to guarantee, and inspections take a long time. It is not conducive to the optimization of the construction period and cannot ensure the quality of work. Contents of the invention [0003] In view of the above problems, the object of the present invention is to solve the problems raised by the background technology, and provide a three-dimensional scanning-based pipeline position inspection method with high i...
