Description

{TRAIN ACCESS WARNING SYSTEM}

The present invention relates to a concrete ultrasonic measurement assisting apparatus, and more particularly, to a concrete ultrasonic measurement assisting apparatus capable of being used in various kinds of concrete environments by adjusting a distance between a transmission probe and a receiving probe, And an ultrasonic measurement assisting device.

In general, the strength, cracks, etc. of concrete structures should be inspected to check the construction, curing, safety, and continuity of use of concrete structures.

For this purpose, it is the most accurate method to destroy part of concrete structure. However, due to the surrounding situation, it is not possible to measure by fracture and the condition of concrete structure deteriorates due to damage or time and cost are incurred.

Therefore, for the measurement of concrete structures, non-destructive inspection is mainly performed to preserve the concrete structure in a state without damaging the concrete structure and to prevent the appearance from being deteriorated.

Such non-destructive testing methods include visual inspection, radiographic inspection, magnetic inspection, ultrasonic inspection, leakage inspection, and impact echo inspection.

Among these inspection methods, ultrasound is the most accurate and easy to operate, and can quantify the measured values and results.

The ultrasonic inspection includes a transmission probe and a reception probe contacting the surface of the concrete structure, and an ultrasonic measurement body connected by the cable to the probes.

For example, the ultrasonic inspection first displays measurement points at intervals of about 10 cm along the horizontal and vertical directions using chalk and a ruler to indicate the measurement position of the surface of the concrete structure.

Then, when grease is applied to a measurement point displayed on the surface of the concrete structure, and then the transmission transducer and the reception transducer are brought into contact with each other, the measurement signal of each transducer is transmitted to the ultrasonic measurement body so that the measurement result value can be known.

In these ultrasonic examinations, the transmitting transducer and the receiving transducer are generally separated so that the distance between the transducers must be measured one by one.

In order to measure ultrasonic waves at the next measurement point displayed on the surface of the concrete structure, the ultrasonic waves are measured by moving the other transducers to the next measurement point while leaving the transducers of the transmission transducer or the reception transducer intact.

In this case, since the crack depth measurement result of the concrete structure is required at this time, there is a disadvantage that the measurement time is too long in addition to the troublesome and inconvenient work in the operation.

For the above reasons, in the related field, a method of efficiently checking the strength, crack, etc. of the concrete structure in a short period of time has been searched. However, up to now, satisfactory results have not been obtained.
