盾构机同步注浆管路的结构优化

Optimizing Structure for Simultaneous Back Filling Pipelines of Shield Machine

摘要: 由于在盾构施工过程中经常出现同步注浆管路堵塞现象，盾构机制造厂家及盾构施工单位均在通过不断的研究和实践，试图设计出一种更加合理和实用的同步注浆管路结构形式。本文介绍了几种不同结构形式的注浆管，并通过分析比较各自的优缺点，结合盾构施工过程中的实际情况，优化设计出一种新型的注浆管结构形式。

Abstract: During the tunneling construction, the simultaneous back filling pipelines often being jammed, the shield manufacturers and construction units are trying to finding out a more appropriate structure of simultaneous back filling pipelines to avoid jam. In this article, the author firstly introduces some different structures of simultaneous back filling pipelines, compares and analyzes their advantages and disadvantages according to the tunneling construction’s practical conditions, optimizing a new type structure of simultaneous back filling pipelines.
