地下管线探测的对象包括埋设于地下的给水、排水、燃气、热力、工业等各种管道;电力、通讯等各种光(电)缆,尤其应注重污水治理、合流污水的大型顶管;大口径雨水管道;军用光(电)缆;无法搬迁或搬迁成本巨大的重要管线。施工前的准备工作主要包括:资料搜集、现场踏勘、仪器一致性校验、方法试验、技术设计书的编制、技术培训和项目作业计划编制等内容。准备工作完成后,组织人员进场进行探查、测量和数据处理、图形编绘和建立地下管线数据库等工作。
Underground pipeline detection targets include buried in the ground water, drainage, gas, heat, industry and other pipes; electricity, telecommunications and other optical (electrical) cables, with particular emphasis on sewage treatment, confluence of sewage pipe; Caliber rainwater pipe; military optical (electric) cable; unable to relocate or relocate a significant costly pipeline. Preparation before construction mainly includes: data collection, site reconnaissance, instrument consistency verification, method testing, technical design book preparation, technical training and project work plan preparation and so on. After the preparation is completed, personnel are organized to enter the site for exploration, measurement and data processing, graphic compilation and establishment of an underground pipeline database.
