东庄站—会展中心站区间盾构管片拼装技术

Assembly technique of shield segment in Dongzhuang station-convention & exhibition center station tunnel

盾构管片拼装质量直接决定成型隧道的质量。从管片类型选择、拼装位置确定、管片类型及拼装位置预测、管片直楔环配合比、直曲线隧道拟合、拼装施工的技术要领、质量要求等方面开展研究,得出了一些有意义的结论。

The quality of shield segment assembly directly determines the quality of shaped tunnel. This paper studies the selection of segment type,determination of assembly position,prediction of segment type and assembly position,proportion of segment straight wedge ring,fitting of straight curve tunnel,technical essentials and quality requirements of assembly construction,etc.,some meaningful conclusions are drawn.
