The invention discloses a grouting sleeve monitoring device based on acoustic distance measurement and a use method, and relates to the field of hydraulic building construction safety monitoring. The device is installed in a space between the inner wall and the outer wall of a grouting sleeve, and the device comprises a sound wave receiving and transmitting module used for transmitting sound signals within a certain frequency range, receiving sound signals returned after being reflected in the grouting sleeve and transmitting the signals to a signal processing module; and the signal processing module used for receiving the reflected sound signals received by the sound wave receiving and transmitting module and processing the sound signals to obtain the length of a pipeline and the height of a grouting material. The device solves the problem of monitoring of damage in the grouting sleeve and the problem that the height of the grouting material in the grouting sleeve cannot be monitored in real time during grouting, and compared with an existing device, the device is low in price, convenient to operate and more convenient to maintain and repair.
Description
technical field [0001] The present application relates to the technical field of grouting sleeve monitoring, in particular to a grouting sleeve monitoring device based on acoustic distance measurement and a method of use thereof. Background technique [0002] Many scholars at home and abroad have proposed many offshore grouting sleeve defect monitoring technologies based on different monitoring principles. It mainly includes: X-ray detection grouting sleeve, direct impact vibration detection grouting sleeve, impact echo method detection grouting sleeve, pre-embedded steel wire drawing method detection grouting sleeve. Among them, the X-ray detection method cannot monitor the grouting sleeve in real time, and at the same time, due to equipment reasons, it cannot achieve lightweight, which cannot be realized on the engineering site; the impact echo method cannot detect the inside of the grouting sleeve during the grouting operation. At the same time, due to the short distance...
