建设期数字化管道竣工测量数据的采集

Acquisition of completion survey data for digitized pipeline during construction

竣工测量数据采集是数字化管道施工建设管理的重点。以西北某在建数字化管道为例,阐述了竣工测量数据采集方法、测量成果的质量控制及其应用效果。管道建设期的数据采集方法包括推算法、几何法、RTK测量法,其中RTK测量技术因其精度高、实时性和高效性强,成为数字化管道竣工测量数据采集最主要的方法。测量成果的质量控制方法主要有多次校核测量、布设便捷的控制点、采集精准测量信息、通过GIS系统检查测量信息。实例应用结果表明,管道建设期的数据采集方法保障了管道竣工测量成果表数据的真实性、准确性,主要具有3大作用:辅助出竣工图,减少工作量;辅助出竣工资料,保证与竣工图数据统一;为管道运行期提供技术支持。(图2,参5)

Completion survey data acquisition is the focus of the construction management for digitized pipeline. A digitized pipeline under construction in the northwest is taken as an example to state completion survey data collection methods, survdy result quality control and application results. Data acquisition methods during the pipeline construction include reckoning method, geometric method and RTK survey method, of which the RTK survey method has become the primary method used for completion survey data acquisition of digitized pipelines due to its high accuracy, timeliness and high efficiency. Survey result quality control methods mainly include repeatedly checking survey, arranging convenient control points, collecting precise survey information and checking survey information by means of a GIS system. Application results of the example have shown that data acquisition method during the pipeline construction can ensure true and accurate data of pipeline completion survey result table and play four major roles, that is, assisting preparation of as-built drawings to reduce workloads, facilitating preparation of completion data and ensuring consistency with the as-built drawing data, and providing technical support during pipeline operation. （2 Figures, 5 References）
