Device and method for ultrasonic detection of concrete column quality based on global transit time parameters

Abstract

The invention discloses a concrete column quality supersonic detection device based on universe transition time index and a detection method thereof. The device comprises a signal exciting module, a signal amplifying module, an energy converter array, an array switch, a transition time index collecting module, a data storage module, and a supersonic imaging module; wherein the energy converter array is composed of a plurality of energy converters which can emit and receive supersonic signals, the energy converters are circularly arranged on the periphery of a concrete column to be detected; the signal output terminal of the signal exciting module is connected to the signal input terminal of the signal amplifying module, the signal output terminal of the signal amplifying module is connected to the signal input terminal of the energy converter array, and the signal output terminal of the energy converter array is connected to the signal input terminal of the transition time index collecting module. The concrete column quality supersonic detection device can carry out detection on a concrete column in all directions, can precisely detect the information of defects existing in the inner side of a concrete column, and then visually shows the information in supersonic images; so that the quality of concrete columns can be more effectively detected and observed.

Description

technical field [0001] The invention relates to an ultrasonic detection device and method for concrete column quality based on global transit time parameters, and belongs to the technical field of ultrasonic detection. Background technique [0002] At present, concrete ultrasonic testing technology began in the late 1940s. Due to the advantages of wide application, large distance measurement, and no damage to structures, this technology has been rapidly popularized at home and abroad, and has become the most widely used non-destructive testing of concrete. Method, my country has carried out the research of this technology since the mid-1950s, and has made significant progress in both detection technology and instrumentation, making this technology widely popularized and applied in various domestic construction projects, improving project quality, eliminating hidden dangers, and ensuring Safety has played a huge role. In 1980, concrete ultrasonic testing technology was first in...

Problems solved by technology

[0008] However, the detection of concrete columns in the prior art often uses a pair of ultrasonic generators and ultrasonic receivers to detect concrete columns, which requires detection of multiple data and the need to move the pair of ultrasonic generators and ultrasonic receivers, which is very cumbersome, and The measurements are also inaccurate
