Synchronous Grouting Monitoring System
同步注浆监测系统
GPR-based synchronous grouting monitoring system for dynamic quality monitoring of shield tunnel backfill grouting and detection of voids behind segment linings
基于无线探地雷达的同步注浆质量动态监测系统，用于盾构壁后注浆质量监测和管片背后空洞检测
Supplied by Fujian Zhongtian Traffic Engineering Technology Service Co., Ltd.
Overview
Product overview
The synchronous grouting monitoring system is composed of a WGPR wireless ground penetrating radar host system, an arc-shaped rotating bracket with sprocket-driven scanning, a tunnel-specific base, and mobile phone or tablet transmission terminals. It supports dynamic monitoring of synchronous grouting quality in shield tunnels and can detect voids behind segment linings and insufficiently compacted grouting defects.
同步注浆监测系统由WGPR无线探地雷达主机、弧形旋转支架与链轮驱动扫描系统、隧道专用底座以及手机或平板传输终端组成。系统可用于盾构隧道同步注浆质量动态监测，并可检测管片背后空洞及壁后注浆不密实缺陷。
