Real-time monitoring system and method for concrete vibration

Abstract

The invention discloses a real-time monitoring system for concrete vibration, and the system comprises a real-time data analysis and processing unit, an optical fiber sensing and detecting unit, and asensing optical fiber, wherein the sensing optical fiber is arranged in a concrete pouring area, and the optical fiber sensing and detecting unit is configured to receive an optical signal sent by the sensing optical fiber and analyze the optical signal to obtain vibration data including at least the optical fiber; the real-time data analysis and processing unit is configured to analyze the vibration data to obtain at least the vibration position information of a vibration rod. The invention also discloses a real-time monitoring method for concrete vibration, which is implemented by the system described above. By adopting the above technical solution, the optical fiber is used as a sensor to replace the original point sensor, which has flexible networking and small limitations, and can meet the vibration monitoring in various complex environments. The distributed optical fiber sensing technology can be used to obtain more accurate and reliable vibrating monitoring results than traditional methods, and can quickly adapt to the construction site environment with no need to modify the vibrating rod.

Description

technical field

[0001] The invention relates to a concrete vibrating real-time monitoring system and method, belonging to the technical field of concrete construction. Background technique

[0002] In the construction of roads, bridges, tunnels, etc., there will be a lot of air in the concrete after mixing, transportation and pouring into the mold. Filled with concrete without creating voids. Therefore, the principle of vibratory liquefaction is used to vibrate the poured concrete to increase its fluidity after liquefaction and fill the entire formwork, so that the concrete particles are closely combined, and the air trapped inside the concrete is discharged from the surface of the concrete, thereby To achieve dense and firm concrete. The greater the amount of concrete pouring, the more air bubbles, the greater the void ratio, and the poorer the compactness. Only through vibration can the problem of concrete compactness be solved. It is to ensure that the concrete is compa...
