鄂北调水工程PCCP管道安装测量监理质量控制

根据鄂北地区水资源配置工程生产性试验项目大型PCCP管道施工特点,结合管道安装测量中常见问题,重点阐述了测量监理质量监督与检测方法,在监理过程中,理论与实际检测相结合,有效地控制了管道施工中沟槽深度、坡度、管线长度、安装高程等测量限差,使得管道安装各项质量指标得到了有效地保证。为后续全线PCCP管道安装测量积累了实践经验,亦可为同类输水工程的测量监理质量控制所借鉴。

Quality control for supervision of PCCP pipeline installation and measurement in North Hubei Water Transfer Project

According to the characteristics of large PCCP pipeline installation in pilot production of water resources allocation project in North Hubei and considering the repeated problems in pipeline installation and measurement, we focus on introducing quality supervision and checking methods of measurement supervision. In the process of supervision, the combination of theory and practical check can effectively control the measurement tolerances of trench depth, gradient, pipeline length and installation elevation in pipeline construction and ensure the quality indexes of pipeline installation. The experiences can be used in the fol-low-on installation measurement of PCCP pipeline and as reference for measurement supervision of similar water transfer project.
