混凝土振捣3D可视化质量监控系统研究应用

Research and Application of 3D Visualization Quality Monitoring System for Concrete Vibrating

为满足混凝土浇筑过程质量的精准量化评价和监控需求,设计开发了人工振捣混凝土工艺效果的3D可视化系统。首先介绍了系统采用的GNSS-RTK精确动态定位技术,实时采集振捣棒在浇捣混凝土时的振捣轨迹,并结合有效振捣持续时间采集获取定量化振捣工艺参数;其次,应用混凝土浇筑体构件的3D实体建模和现场定位技术,并基于实时获取的量化振捣参数,动态展示构件浇筑部位的实时振捣效果,指导施工人员对欠振、漏振区域及时补救;最终实现混凝土振捣状态3D可视化动态监控。

In order to meet the requirements on accurate quantified evaluation and real-time monitoring on the quality of concrete pouring process,a 3 D visualized system is developed which can display the effect of manual concrete vibration. Firstly,the GNSS-RTK precision dynamic positioning technology used in the system is introduced,Which can collect real-time vibration traces of the vibrator when pouring and vibrating the concrete,and acquire quantified vibration parameters based on the effectively continuous duration of vibration. Secondly,by using the 3 D modeling and field positioning technologies for concrete members and based on the acquired real-time quantified vibration parameters,the real-time vibrating effect of the pouring locations of the structures can be displayed on a dynamic basis. It enables guiding constructors to timely vibrate the areas not sufficiently vibrated or not vibrated at all,finally it realizes 3 D visualized dynamic monitoring on the state of concrete vibration.
