Study On Construction Progress Management Of Hncs Branch Line Project Of The West-east Gas Pipeline

Since the end of the 20 th century,the world's three major energy sources: oil,natural gas,coal,as people pay more and more attention to the environment of life,natural gas is a green,environmentally friendly,environmentally friendly and high-quality energy.It contains almost no sulfur,dust and other harmful substances.It produces less carbon dioxide when it burns than other fossil fuels,causing a greenhouse effect.Low,thus fundamentally improving the quality of the environment.Compared with gas,natural gas has the same calorific value,while natural gas is clean and clean,which can extend the life of the cooker and help users reduce maintenance costs.Natural gas is a clean natural gas supply that is stable and can improve air quality,thereby providing new impetus to the economic development of the region,driving economic prosperity and improving the environment.more economics.Natural gas is non-toxic,easy to disperse,lighter than air,and should not accumulate as explosive gases.This is a safer gas.The use of safe and reliable natural gas in the home will greatly improve the home environment and improve the quality of life.Industrial production is increasingly using and promoting this clean energy.This also led to the use of natural gas as an effective means to change environmental pollution in China,and the high efficiency and safety of oil and gas pipeline transportation has also been collectively supervised by the society,aiming at the laying of long-distance oil and gas pipelines.The project construction ensures the normal system operation and use of the long-distance pipeline network in each region,and better serves the use of natural gas in the society.The development of China's oil and gas industry has become the driving force of social development.Long-distance natural gas pipelines often encounter many problems during construction investment,such as long distances,large calibers,high pressures and complex topography,which are encountered during the construction of long-distance natural gas pipelines.There are many factors that have affected the progress of pipeline construction during construction delays.It is necessary to start with project planning,construction organization,resource input,fund guarantee,coordination of workers and farmers,change management,etc.,and take effective measures to ensure the progress of pipeline construction.Project schedule management is a very important task of project management and can fully reflect the implementation of the project.A good way to implement schedule control management during the construction phase is to ensure that the construction unit executes the contract and that the project is completed as scheduled.This paper mainly analyzes the influencing factors of project schedule management and proposes the influencing factors of specific management measures.Construction project schedule control is the same investment control and quality control,and is one of the key controls of the project construction process.It is an important measure to ensure that construction projects are completed on schedule,rationally arrange resource supply,and save engineering costs.In order to ensure the total construction period target,the implementation of the rush processing,each construction node and construction process are to increase the amount of resources input and construction team plan,should first determine whether the current process is a key process,for the construction process not in the critical line does not use the rush or increase The handling plan of the construction team,for the rushing process that occurs during the shortening of the construction period of each key process,should also take into account the most cost-saving premise of the key process of the rush processing or additional construction team,for some not on the critical line In the case of a lag in the process,it is necessary to have a reasonable analysis of whether the critical line has been changed,and a reasonable study of the total time difference of the process,whether to use the rush processing or increase the construction team for construction.This paper analyzes the deviations between the construction schedule and actual progress of the West-East Gas Pipeline Changsha branch line project in the Hunan-East China Interconnection Project of the West-East Gas Pipeline.Based on the existing problems,some construction process schedules lag behind during the construction phase of the project.Analyze each process to explore whether the process lag is affected by the total construction period,the process on the critical line is delayed,the cost of the compression process is rationally analyzed,the most reasonable rushing measures are selected,and the construction progress is proposed.Safeguard program.In the actual program,the management functions are used to improve and summarize,and the overall control over the project duration is achieved.
