浅谈PPS导向系统

Discussion of PPS guidance system

介绍PPS导向系统的工作原理,提出系统运行过程中的管理维护内容与措施,根据PPS系统的定位原理,了解TBM在掘进过程中的偏差因素,采取对其纠偏的措施,可保证TBM严格按设计坐标方位掘进。

The operation procedures and cautions during the installation of PPS guidance system are summarized,the management contents and maintenance measures of PPS guidance system are proposed, Based on the orientating pinciple of the system,the tunneling of TBM can be guaranteed to be made exactly along the designed line.We can find out the factors of the tunneling error from TBM during the tunneling and tak the related measures for the error modification.
