长输管道施工要点及质量控制探讨

Construction Points and Quality Control of Long-Distance Pipeline

青藏高原地区独特的地理环境和气候特征给长输管道施工带来了巨大挑战。笔者结合青藏高原地形和环境的特点,从材料控制、焊接控制、安装过程控制等方面探讨长输管道施工质量控制要求;重点分析穿越冻土层、沼泽等特殊地质条件下的管道施工要点,以及管道防腐处理和施工安全等关键环节的控制要求。提出加强施工前准备、严格执行规范标准、强化质量意识和责任意识、加强技术创新和培训等提高长输管道施工质量的具体措施,为青藏高原长输管道施工质量提供保障。

The unique geographical environment and climatic characteristics of the Qinghai-Xizang Plateau have brought great challenges to the construction of long-distance pipelines.Based on the characteristics of the terrain and environment of the Qinghai-Xizang Plateau,the author discusses the quality control requirements of long-distance pipeline construction from the aspects of material control,welding control and installation process control.The key points of pipeline construction under special geological conditions such as frozen soil and swamp are analyzed,as well as the control requirements of key links such as pipeline anti-corrosion treatment and construction safety.The specific measures to improve the construction quality of long-distance pipeline are put forward,such as strengthening the preparation before construction,strictly implementing the standard,enhancing quality and responsibility awareness,and strengthening the technical innovation and training,so as to provide guarantee for the construction quality of long-distance pipeline in Qinghai-Xizang Plateau.
