Intelligent detection method for vibration effective depth

Abstract

The invention relates to a vibration quality control technology in concrete pouring construction of hydraulic engineering, in particular to an intelligent detection method for vibration effective depth. The intelligent detection method comprises the following main steps that sensors are adopted to collect real-time operation information of a vibrating machine / beam in an operation process, the real-time operation information, including the insertion depth of the vibrating machine / beam, the slant angle of the vibrating beam, and the switching state of the vibrating beam, is monitored in real time, through comprehensive analysis, the effective insertion depth of the vibrating machine / beam is accurately obtained, the effective vibrating time of the vibrating machine / beam is counted, a positioning module is adopted to obtain the operating coordinates of the vibrating machine / beam, so that the vibration quality of a concrete bin face is comprehensively monitored. The intelligent detection method for the vibration effective depth has the beneficial effects that the implementation mode is simple, manual intervention is not needed, the error caused by artificial judgment is solved, the vibrating monitoring process is enabled to be intelligent, and the obtained data is high in precision and stable and reliable. The intelligent detection method is particularly applicable to the large volume concrete vibration quality control of the hydraulic engineering.

Description

technical field [0001] The invention relates to a vibration quality control technology in concrete pouring construction of a water conservancy project, in particular to an intelligent detection method for effective depth of vibration. Background technique [0002] In concrete construction, vibration is the key to the quality of concrete buildings. If the concrete is not sufficiently vibrated, it may cause the internal pores of the concrete to be too large and too many, which will affect the strength of the concrete, increase the permeability of the concrete, reduce the durability, and may cause honeycomb pitting; if the vibrating is excessive, it may cause segregation of aggregate and slurry , the aggregate at the bottom is concentrated, the bonding is insufficient, the surface is flooded, and the interlayer bonding is affected. Therefore, the control of the vibration process is particularly important. [0003] On-site operators conduct quality control based on experience,...

Problems solved by technology

In actual operation, when workers move the vibrating point, they cannot accurately grasp the position, depth, and effective vibrating time. Most of them are empirical operations, which are highly random and are greatly affected by human factors and working conditions; Vibration, over-vibration, missing vibration, and vibration will not meet the construction quality requirements, leaving quality defects and cannot be known in time

This has become a common problem in the vibration quality of concrete pouring. At present, there is no accurate and effective technical solution at home and abroad.
