云图监测系统在地铁隧道内壁后注浆施工中的应用

Application of Yuntu monitoring system in post grouting reinforcement of inner wall subway tunnel

根据南京地铁2号线某区间盾构隧道壁后注浆加固云图自动化监测实例,介绍了自动化测距仪远程监测系统在隧道内壁后注浆过程中进行单圆隧道直径收敛监测的应用,并通过全站仪人工收敛监测数据对其进行检校对比,结果表明,该云图自动化监测系统所获数据具有较高精度,可及时判断地铁隧道结构的安全性,胜任隧道壁后注浆的监测工作。

Image automatic monitoring according to the example of grouting reinforcement of Nanjing metro shield tunnel line 2 wall, introduces the remote monitoring system of automatic range finder using single circle diameter of tunnel convergence monitoring in tunnel wall grouting process, and the total station artificial convergence monitoring data for the calibration and comparison. The results show that the image data from the automatic monitoring system with high precision, timely judgment of the subway tunnel structure safety monitoring work, grouting tunnel wall.
