曲线顶管自动测量系统的应用

Application of automatic measurement system for pipe jacking used in curve designed axis tunnel

在长距离或曲线顶管工程中,及时准确测量前端顶管机的位置和姿态,是确保管道按设计轴线顶进的关键技术手段,不管是与直线顶管机的位姿测量相比,还是与盾构机相比,长距离和曲线顶管的位姿测量难度均更大。针对该问题本文进行了专项研究,研发一套曲线顶管自动测量系统且详细介绍了此系统,对系统的设计原理、工作流程进行阐述,并结合应用数据成果进行分析,优化系统精度。

In the long distance or curve pipe jacking project, timely and accurate measurement of the position and posture of the front pipe jacking machine is a key technical means to ensure the pipe jacking according to the design axis. Whether it is compared with the position and attitude measurement of the linear pipe jacking machine or compared with the shield machine, the measurement of the position and posture of the long distance and curve jacking pipe is more difficult. This paper has carried out a special research on this problem, and developed a set of curve pipe jacking automatic measurement system. It introduces the system in detail, expounds the design principle and work flow of the system, and analyzes the application data results to optimize the system accuracy.
