Design And Realization Of The Construction Technology Of The Station In The Subway Construction

With the rapid development of the construction market and the rapid expansion of urban rail transit facilities,cities across the country have begun to carry out subway construction.With the support of the national "going out" and "Belt and Road"development strategies and in order to build an intensive society and achieve sustainable development Development,urban land resources in the increasingly scarce trend of the situation,the three-dimensional urban construction,urban construction of the cross-track,more and more become a trend.At the same time,the three-dimensional construction technology is more and more difficult,the three-dimensional construction of the surrounding environment is more and more complex,how to ensure the existing structure in the construction of the three-dimensional cross,both the safety and stability of the existing building is the next urban three-dimensional cross Construction,especially in the construction of heavy and difficult.The expansion of urban subway construction scale,the operation network has been initially formed,the construction environment is more and more complex,the new station under the existing section,the stations are also more and more projects,resulting in more and more new lines buried depth,belt The technical problems to larger.In this paper,Beijing Metro M6 West extension of Apple Orchard Station under the existing Metro MI line apple orchard construction as an example to study the apple orchard traffic hub as a key development project in Beijing,from the project planning to the current preparation and implementation has undergone a careful study,Design and demonstration.As one of the important transport hubs planned in Beijing,a comprehensive study and discussion of its construction process can provide reference and experience for similar projects.The construction under the existing line is a special-risk project in the subway construction.The existing structure is guaranteed during the construction.The safety and stability of both the existing structures are heavy and difficult points in the subway construction,especially for the subway station.Beijing Metro Line 6 West Yan Apple Orchard Station under the existing line M1 Apple Orchard Station project,mainly from the perspective of underground excavation construction of urban subway station station under construction technology design and implementation,through the design according to the design Subway station underground excavation design,summed up the experience in the construction,control of construction settlement,the subway station construction in urban subway construction technology research summary,more effective in construction control,and for similar subway station Wear construction provides experience,at the same time for the subway station under the design to provide relevant basis.
