Construction Suggestions and Application of Sound Barrier of Existing Line of Beijing-Yuanping Railway

为使京原铁路声屏障工程符合临近既有线施工原则,保证既有铁路运营安全,提出京原铁路既有线声屏障施工建议并进行应用分析,充分考虑工程的各种施工条件,扬长避短,拟定合理的施工方案,确定施工顺序、施工方法和施工经济性组织措施,针对施工现场出现的一些问题,合理统筹安排拟定施工进度计划,积极推行新工艺、新材料、新机具等施工方法手段,以提高施工效率、降低工程费用,并重视技术创新和合理化建议工作。

In order to ensure the operation safety of the existing railway during the sound barrier construction of the Beijing-Yuanping Railway under the principle of conforming to the construction of the adjacent existing line, this paper puts forward the construction suggestions on the sound barrier of the existing line of BeijingYuanping Railway, and carries out application analysis. We fully consider various construction conditions of the project, and develop strengths and circumvents weaknesses, to formulate a reasonable construction scheme,determine the construction sequence, construction methods and construction economic organization measures.For some problems arising on the construction site, we make reasonable and overall arrangements to formulate the construction schedule, actively promote the construction methods and means such as new processes, new materials and new machines and tools to improve the construction efficiency and reduce the project cost, and focus on technological innovation and rationalization suggestions.
