无人机在铁路总承包建设施工中的应用

Application of UAV in the construction of Railway General Contract

相较于其他建设工程,铁路工程总承包项目具有跨越区域广,线路所在区域地形、地貌复杂等特点,这给工程管理带来很大难度。无人机具有机动、灵活、数据获取精度高等特点,通过无人机开展铁路施工现场数据采集与应用,可为铁路总承包项目施工管理提供直观数据支持。从常见无人机类型与特点、无人机外业数据采集、无人机多源数据处理、无人机成果数据系统化管理与应用等方面展开论述,对工程总承包中不同数据类型的采集模式、要点进行了总结,对内业数据处理的相关技术思路进行归纳。在对多源数据采集与处理的基础上,设计并构建基于BS架构总承包无人机应用系统,实现了工程总承包无人机数据的系统化存储、管理与应用。该研究可为铁路总承包中的形象进度、施工质量安全、征拆进度、环水保等方面管理提供有效技术支持。

Compared with other construction projects,the railway project general contracting has a wide range of areas,and the terrain and geomorphic environment of most of the line areas are complex,which brings great difficulties to the project management.UAV has the characteristics of maneuverability,flexibility and high accuracy of data acquisition.Through UAV to carry out data acquisition and application in railway construction site,it provides intuitive data support for construction management of railway general contracting project.This paper mainly discusses the types and characteristics of common UAVs,field data acquisition,UAV multisource data processing,UAV achievement data systematic management and application.This paper summarizes the collection mode and key points of different data types in EPC,and sums up the relevant technical ideas of interior data processing.On the basis of multi-source data acquisition and processing,a general contracting UAV application system based on BS architecture is designed and constructed,which realizes the systematic storage,management and application of EPC UAV data.It provides effective technical means for the management of image progress,construction quality and safety,acquisition and demolition progress,environment and water conservation in Railway General Contract.
