Title:
UNDERWATER DETECTION SYSTEM FOR CAVITY REGION OF CONCRETE PANEL ROCK-FILL DAM BASED ON ACOUSTIC WAVE SENSING
Document Type and Number:
WIPO Patent Application WO/2019/192266
Kind Code:
A1
Abstract:
An underwater detection system for a cavity region of a concrete panel rock-fill dam based on acoustic wave sensing, comprising a moving platform, an acoustic wave producing apparatus, an acoustic wave receiving apparatus (9), a traction apparatus, and a positioning apparatus (4); the acoustic wave producing apparatus and the positioning apparatus (4) are arranged on the moving platform, the traction apparatus controlling the movement of the moving platform on the surface of a concrete panel (13); the acoustic wave producing apparatus produces a penetrative acoustic wave, and the acoustic wave receiving apparatus (9) receives the acoustic wave and determines whether there is a cavity region on the basis of the acoustic wave signal, the position of the cavity region being transmitted by means of the positioning apparatus (4).
