Transmission tower concrete foundation internal defect identification method and system

Abstract

The invention discloses a transmission tower concrete foundation internal defect identification method and system, and the method comprises the steps: the design data of a to-be-detected foundation iscollected, and a detection range is determined through the design data; seismic scattered wave signals are detected and collected; data processing is carried out on the collected seismic scattered wave signals, the stratum velocity structures of all shot points are obtained through velocity analysis, and a stratum wave velocity distribution image can be obtained by integrating the velocity structures of all the shot points; and analyzing and deducing are carried out on the stratum wave velocity distribution image to determine the internal defects of the concrete foundation of the power transmission tower. According to the embodiment of the invention, the method and the system achieve the recognition of the internal defects of the concrete foundation of the power transmission tower, are low in cost, improve the detection efficiency, are simple in operation, and are high in applicability.

Description

technical field [0001] The invention relates to the field of detection, in particular to a method and system for identifying internal defects of concrete foundations of power transmission towers. Background technique [0002] The iron tower in the transmission line is an extremely important basic support facility in the power line. The concrete foundation of the transmission tower is the key structure supporting the tower. Ensuring its sufficient safety is an important prerequisite and basis for ensuring the safe operation of the power line. However, in the actual construction process, due to the influence of objective conditions on site, human subjectivity and other factors, there are certain proportions of defects in the construction quality of the tower concrete foundation. Through on-the-spot research, it was found that the concrete foundation of the transmission tower has various defects inside the foundation due to irregular construction, such as inward depression, mud...

AI Technical Summary

Problems solved by technology

The existing means of inspecting the internal defects of the transmission tower foundation mainly adopts the method of manual excavation and visual inspection. This kind of method belongs to destructive testing, which will destroy the stable embedding conditions of the original foundation, and there are also problems such as high cost and low efficiency. , and it is impossible to check the interior of the foundation in detail after the tower is erected
