A Quality Inspection Method for Cylindrical Bridge Piers Based on Data Slicing

Abstract

The invention provides a cylindrical pier quality detection method based on data slices. The cylindrical pier quality detection method includes the steps that original detected data records are acquired; digital signal processing is conducted on the amplitude A of the original detected data records, and then processed detected data are acquired and recorded as lambda; processed detected data records are analyzed, and three-dimensional space coordinate values of each sampling point in each data record in each profile data record are calculated and acquired; based on three-dimensional imaging software, the three-dimensional space coordinate values of each sampling point and the data lambda acquired after digital signal processing is conducted serve as input, and a radar detection three-dimensional imaging graph reflecting the pier pouring quality defect is acquired. The method has the advantages that on the premise that concrete performance is not affected, the internal quality of a cylindrical pier is detected in a lossless mode, the three-dimensional imaging graph reflecting the pier pouring quality defect is quickly re-established through a simple method, the position, the shape and the range of the concrete internal defect are more visually reflected, and higher accuracy and reliability are achieved.

Description

technical field [0001] The invention belongs to the technical field of engineering quality detection, and in particular relates to a method for detecting the quality of cylindrical bridge piers based on data slices. Background technique [0002] Bridge piers are the main supporting structures of bridges, and their bearing capacity and durability directly affect the overall safety of bridge structures. Due to the influence of various factors such as natural environment, accidental impact and concrete aging, even under normal operating conditions, bridge piers are often damaged to varying degrees. Therefore, it is necessary to regularly inspect the quality of bridge piers to ensure their safety in use. [0003] At present, the commonly used methods to detect the quality of bridge piers include: springback method, core drilling method, after-installation pull-out method, etc. Among them, the rebound method can only detect the hardness of the concrete surface of the bridge pie...

AI Technical Summary

Problems solved by technology

Among them, the rebound method can only detect the hardness of the concrete surface of the bridge pier, but cannot detect the internal defects of the bridge pier; the core drilling method and the after-installation extraction method are semi-damage detection methods, which will cause local damage to the pier structure, although it will not affect The bearing capacity of the component, but the disadvantage is that it needs to repair the local damage, so it has great limitations in use
