Embodiment Construction

[0030] The details of the non-destructive inspection device and inspection method of a composite structure using cosmic ray muons according to the present invention will be described below.

[0031] figure 1 The outline of the overall structure of the non-destructive inspection device of the composite structure part of this invention is shown. The non-destructive inspection device of the present invention is characterized by using cosmic ray muons 12 that are polarized with a given amount of spin in the direction of travel and travel substantially in the horizontal direction. Furthermore, the present invention uses the cosmic ray muons to inspect the inside of the surface layer of a composite structure.

[0032] exist figure 1 A composite structure 11 to be subjected to a non-destructive inspection is a reinforced concrete 11 composed of concrete 11-1 at the surface layer and steel bars (or steel frames) 11-2 inside.

[0033] like Figure 11As shown, the non-destructive in...

Abstract

A device for nondestructively examining the inside of the surface layer of a composite structure by using muons of cosmic rays and a nondestructive examination method are disclosed. The device is used for examining the inside of the surface layer of a composite structure (11) by using mu ons (12) of cosmic rays traveling generally horizontally and having spins polarized by predetermined degrees in the traveling direction. The device includes a positron / electron amount detecting means (13) for detecting the amount of positrons / electrons having characteristic time constants and reflected / emitted in the opposite direction to the direction of application of muons (12) when muons (12) which come to rest inside the composite structure (11) annihilate and radiography data processing means (14, 15, 16) for processing data relating to the state of a second substance (11-2) different from a first substance (11-1) of the surface layer present inside the surface layer of the composite structure (11) according to the detected amount of positrons / electron and outputting the state of the second substance (11-2) as a radiograph.

Description

technical field [0001] The present invention relates to a non-destructive inspection device and a non-destructive inspection method capable of inspecting the internal state of a composite structure such as a reinforced concrete building without any adverse effect on the structure. Background technique [0002] For example, if the internal state of reinforced concrete structures such as buildings, viaducts, and dams (non-woven state of steel bars, etc.) Ultrasonic methods, infrared thermography methods, radar methods, and X-ray methods have been widely known as non-destructive inspection methods for inspection or detection without physical or chemical adverse effects. However, these methods significantly limit the inspection object, and there are limits on the resolution of the internal state and the depth inside the surface layer that can be detected. [0003] Therefore, the inventors of the present application have proposed a non-destructive inspection method and apparatus...
