Problems solved by technology

[0003] Restricted by the ultrasonic detection method, the current ultrasonic detection method is mostly a single sensor sending and receiving or a sending and double receiving method, and there is no detection method and equipment capable of continuous recording
This kind of detection system cannot continuously measure and evaluate geological targets, and collects data through a single point of transmission and reception. The on-site detection work efficiency is low, and the real-time detection ability is poor. Therefore, the application degree of the geological radar method in concrete engineering testing is insufficient

Abstract

The invention belongs to the technical field of geophysical exploration and discloses an ultrasonic quick scanning exploration method and a system for the same. The method comprises the following steps of: firstly, performing ultrasonic data transmission and reception by utilizing a roller scanning probe (1), and completion automatic recording of different measurement point distances according to a rolling condition; secondly, setting corresponding acquiring technical parameters by an ultrasonic data acquisition controlling and processing system (3) through a data acquisition system, and completing a synchronous acquisition task on data by an ultrasonic data acquisition device (2), thereby obtaining ultrasonic quick continuous scanning data of a measuring line point; and finally, calculating and processing the ultrasonic quick scanning data by the ultrasonic data acquisition controlling and processing system (3), explaining a detection medium according to a test profile result, and determining the abnormal position of the medium in the profile and characteristics thereof. The invention also discloses a system for the ultrasonic quick scanning exploration method. The method improves the field working efficiency of ultrasonic data acquisition.

Description

technical field [0001] The invention belongs to the technical field of geophysical exploration, and relates to an ultrasonic fast scanning exploration method and a system used therefor. Background technique [0002] Ultrasonic detection technology has few interference factors on the test site and is easy to use. It is a practical detection technology that has developed rapidly in recent years. Internally propagated and received by the receiving sensor, by analyzing the received acoustic signal, according to the changes of the acoustic wave velocity, amplitude, frequency and other attribute parameters, the internal structure, mechanical properties and defect distribution of the object can be understood. It is widely used in engineering inspections such as tunnels, roads, and bridges. [0003] Due to the limitation of ultrasonic detection methods, the current ultrasonic exploration methods are mostly a single sensor sending and receiving or a sending and double receiving meth...
