Construction Technique of Long Distance Gas Pipeline under Frozen Soil Condition
In recent years,with the promotion of coal to gas and other related energy transportation projects in the north,the construction scale and number of long distance gas pipelines are also increasing rapidly,and the relevant construction technology is also concerned by construction units and owners.Such projects have the characteristics of tight construction period and heavy tasks,and often cannot avoid seasonal construction,and because of the long winter time in the north,the harsh field construction conditions,and the construction during the frozen soil is inevitable.How to ensure the smooth construction in the frozen soil environment is particularly important.Through this project example,the paper organically integrates practice and theory to analyze the adverse effects of frozen soil on construction projects,and proposes corresponding cost,safety,quality and other control measures after summarizing the actual construction experience,so as to provide reliable experience reference for subsequent similar construction.
