| In recent years,with the rapid development of my country’s economy,railways,as an important engine of the country’s modern economy,have played an important role in supporting and leading economic and social development.High-speed rail has also become the main means of transportation for people.At the same time,in order to solve the problem of low utilization rate of high-speed rail and reduce the operating pressure and heavy debt burden of railway enterprises,China Railway Group actively promotes the use of existing railways to operate suburban trains and other operating modes.On April 14,2018,the Central Committee of the Communist Party of China and the State Council issued the "Guiding Opinions on Supporting Hainan’s Comprehensive Deepening of Reform and Opening-up",announcing the establishment of a pilot free trade zone on the entire island of Hainan.In order to implement the strategy of the Party Central Committee and Hainan Province to promote the construction of Hainan Free Trade Zone(port),promote the rapid development of the Greater Sanya Tourism Economic Circle and the high-quality development of tourist attractions,intensive use of land,and actively promote the development of urban trains and public transportation,China Railway Group Corporation Co-approved with the Hainan Provincial People’s Government the construction of the "Utilization of Hainan West Ring High-speed Rail and Freight Line to Operate Public Transport-oriented Tourist Train Reconstruction Project".The existing Hainan West Ring High-speed Rail Line has 3 stations for use,3stations for reconstruction,and 4 stations for new construction.,2 stations will be renovated and 2 new stations will be built on the West Ring Cargo Line.This article takes the use of Hainan’s West Ring High-speed Rail and Freight Line from Sanya to Ledong(Lingtou)Section to open the public transportation tourist train reconstruction project as the research object,and its characteristics,major and difficult projects,and construction The main processes and safety and quality assurance measures were studied.The main research contents are as follows:1.Comprehensive analysis of the general situation of the reconstruction project for the addition of Liguo Station.First,introduce the background of the reconstruction project of the extension of Liguo Station,the overview of the existing lines and the overview of the design;in view of the use of the existing high-speed rail lines,the focus is on the analysis of the characteristics of the extension of the operating line and the key and difficult projects;finally,the relevant majors are proposed The technical conditions of the interface project and the requirements for entry conditions.2.Overall research on the construction organization design of the reconstruction project for the addition of Liguo Station.Firstly,the preparation principles and overall construction organization arrangements of the additional station reconstruction project are explained,and the construction sequence and key lines of the additional Liguo station reconstruction project are analyzed;secondly,according to the characteristics of the construction of the high-speed rail business line,the transportation organization is detailed Research and clarify the construction skylight plan.Through comprehensive comparison of safety risks,social impacts,economic benefits,construction organization,etc.,determine the plan for selecting construction skylights according to the maximum capacity,and at the same time,to further reduce the impact of construction on transportation The optimization strategy for the construction organization of the business line is proposed,and the safety protection measures for the construction of the business line are analyzed in detail.3.Study the analysis and study of the construction plan of the reconstruction project of the extension of Liguo Station.First,analyze the principles of the overall construction plan for the reconstruction of the additional Liguo Station,and describe the construction preparations in detail;secondly,focus on the construction plan of the project.The reconstruction of the additional station is mainly implemented in seven phases,and the construction Explain the precautions of the stage;again,analyze and study in detail the transition project and important and difficult projects of the additional Liguo station reconstruction project,and determine the corresponding transition construction plan;finally,according to the construction plan of the additional Liguo station reconstruction project,put forward safety and quality And schedule assurance measures.Based on the general situation of the existing West Ring high-speed rail line,as well as the design and analysis of the reconstruction project of adding Liguo Station,this paper studies the construction organization design of the reconstruction project of increasing the Liguo Station.The main construction steps and safety precautions of additional stations on the business line were studied in detail.With the smooth implementation of this project,it can provide reference and reference for subsequent similar projects. |
