自动整平基座在地下工程测量中的应用

Auto-leveling Tripod and Its Application in Underground Construction Surveying

自动化的工程测量要求为测量设备提供持续水平的工作平面。在分析全站仪自动补偿功能的基础上,引入了适用于大倾斜环境下的自动整平基座。分析了其工作原理,讨论了其精度和参数设置及其匹配,研究了自动补偿器和自动整平基座协同工作的基础。在地下隧道工程自动导航系统中的应用表明,自动整平基座与工程测量仪器的自动安平补偿器的配合能很好地解决动态测量引起大倾斜的自动整平问题,其精度可靠、效果良好,对保证地下工程自动导航和顺利贯通具有重要作用。

It is often required to provide continuous level working plane for the measuring equipment in automatic surveying and mapping field.In this paper the automatic leveling tripod is introduced after analyzing the automatic compensation function of the total station,the characteristics of tripod performance are described,then the working principle and foundation of the automatic compensation of total station and automatic leveling tripod are studied.The case study of a pipe jacking system shows that the auto-leveling problem can be solved accurately,reliably and effectively with the joint combination of surveying instruments and automatic tripod,even when the system is in a moving environment.Therefore,the auto-leveling tripod plays an important role in ensuring the automatic navigation and the smooth breakthrough of a project.
