Study On The Line Construction Technology Of The Huamu Village In Fourth Shanxi-beijing Natural

The shanjing four-line gas pipeline project is central Asia important channels of imported and domestic air transport,is an extension of the strategy of "west-east gas" channel,further optimize the general layout of pipe networks.The shanxi-beijing four line of construction,to increase the supply of natural gas in north China,improving the capacity of the winter peak shaving gas supply,control air pollution will play an important role.In order to coordinate with the national action plan on air pollution prevention and control,to gradually eliminate the heavy pollution,the construction speed must be accelerated.During construction,some construction areas may have adverse impacts on the construction period of the whole project due to many aspects of geographical location and environment,so it is necessary to be a local key control project.How to scientifically adapt to the local conditions,the choice of appropriate construction method is the content we need to focus on.This paper takes the shanjing four-line gas pipeline project Hua Mu Village section of line construction as the research object,research and than choose the reasonable construction scheme,It provides reference for the construction method of large-caliber pipeline project in the future.This article main research content includes:Four whole line direction,according to the shanjing four-line and Hua Mu Village period of line of geographical location,environmental impact,and through analyzing factors such as economy,technology,and specify a reasonable construction plan,three construction schemes and the expected to carry on the comparison,provide the basis for the choice of reasonable construction scheme.According to the design idea,the engineering construction scheme is optimized and designed to make it scientific and reasonable,and meet the requirements of national and industry standards and specifications,and provide technical guidance for the implementation of the project.Finally,through the comparison of the design scheme of the top tube tunnel,the paper calculates and verifies the top force of the top pipe,the thickness,strength,stability and earthquake resistance of the pipe,which can meet the requirements of safety performance and verify its feasibility.
