风沙区采用土工格室与土工网保护管道的实践与建议

Practice and Recommendations for Pipeline Protection Using Geogcells and Geonets in Wind-Sand Areas

摘要: 本研究以风沙地区的油气管道防风固沙保护为切入点，依托西部管道管辖的新疆地区的管道工程，通过土工格室和土工网的现场利用，解决了干旱沙漠地区防沙固沙资源有限等问题。从土工格室、土工网沙障影响因素展开分析，在雅满苏压气站沙山风蚀和试验段治理和民勤县沙漠治理两个案例中利用了土工格室和土工网沙障；最后，对应用中存在的问题进行总结分析，并对指标性能和安装要求提出了建议。

Abstract: This study takes the wind prevention and sand fixation protection of oil and gas pipelines in wind-sand areas as the starting point. Relying on the pipeline projects in the Xinjiang region under the jurisdiction of Western Pipeline, it addresses issues such as limited resources for wind and sand prevention in arid desert areas through the on-site application of geocells and geonets. Starting with an analysis of the influencing factors of geocell and geonet sand barriers, the study applies these sand barriers in two cases: the wind erosion control at the sand dunes of YaMansu Compressor Station and the management of the test section, as well as the desert governance in Minqin County. Finally, it summarizes and analyzes the problems existing in the application, and puts forward suggestions on index performance and installation requirements.
