摘要:
泥浆循环系统管路磨损会导致盾构非正常停机,进而影响施工进度并带来安全风险,是泥水盾构施工过程中必须重视的一个问题。结合南京地铁10号线盾构隧道工程实例,针对不同材质、流速、泥浆密度及泥浆中固体颗粒大小等因素对泥浆输送管道的磨损影响进行了研究,通过与实际检测数据对比分析,针对性地提出了减小管路磨损的技术措施,为泥浆循环系统合理化设计、提高施工效率和保证施工安全提供了参考和借鉴。

Abstract:
The pipe abrasion of slurry circulation system will lead to an abnormal stop of shield tunneling and construction risk. Therefore, the influencing factors, including slurry material, slurry transportation speed, slurry density and solid particle size, of slurry pipe abrasion of slurry shield used in Line No. 10 of Nanjing Metro are studied. And then some effective countermeasures for reducing the pipe abrasion of slurry circulation system are proposed by means of comparison between actual testing results and study results,so as to provide reference for rational design of slurry circulation system by improving the construction efficiency and safety.
Key words: Nanjing Metro, slurry shield, slurry pipe abrasion, test analysis
