Problems solved by technology

In traditional concrete vibration quality control, the identification of the concrete pouring and vibrating base layer is carried out through manual spot check records, but in actual operation, only the construction process of the tile method is recorded to identify the pouring and vibrating base layer, and the covering time of the base layer The average coverage time of the entire base layer is derived from the rough estimate, and the vibration quality control of a single base layer is relatively rough, and it is difficult to avoid the leakage of vibration; and for the step method construction process, the identification of the pouring and vibrating base layer and the vibration of a single base layer The tamping quality control is weakened, it is more difficult to obtain the covering time of the billet layer, and it is difficult to avoid the phenomenon of missing vibration, over vibration and under vibration

Abstract

The invention belongs to the technology of vibrating quality control in water conservancy project concrete pouring construction, and discloses a method for monitoring the thickness of a concrete base layer. The thickness of a poured and vibrated base layer can be calculated in real time, the aim of effective monitoring is achieved, and safety production is achieved. The method is technically characterized in that any construction area to be poured and vibrated is selected and divided, a four-dimensional grid corresponding to the construction area is built, then the effective vibrating influence rang is calculated by acquiring vibrating operation information, and is compared and matched with the four-dimensional grid corresponding to the vibrating construction area, the real-time operation position of a vibrating bar is determined, the average height of the four-dimensional grid corresponding to the current vibrating area is obtained through calculation, concrete surface height is obtained through calculation, and finally the thickness of the concrete base layer is obtained by calculating the difference value of the concrete surface height and the average height of the four-dimensional grid corresponding to the current vibrating area. The method is suitable for vibrating quality monitoring.

Description

technical field [0001] The invention belongs to the vibration quality control technology in concrete pouring construction of water conservancy projects, and in particular relates to a method for monitoring the thickness of a concrete blank layer. Background technique [0002] Concrete vibration is the key process of concrete pouring, and the monitoring and control of vibration quality in the process is one of the important links of concrete quality control. At present, in the vibrating construction on the construction site, the staggered insertion of the vibrating rods is used to ensure the full coverage of the concrete pouring area. Most of the extensive empirical methods are used to control the insertion depth, insertion angle, vibrating duration, vibrating spacing, and coverage time of the vibrating rods. And other process control parameters, so as to ensure that the concrete is vibrated compactly. The general empirical control method is: when the concrete no longer sink...
