摘要
天津地铁3号线盾构隧道工程所处地质条件复杂,经研究分析,决定采取综合防水技术方案,即地基加固、盾构进洞前的防水处理和盾构进洞施工中的防水处理。本文就其具体施工工艺作了阐述,如洞门处理、注浆控制等。
The geological conditions of shield tunnel project of Tianjin Metro Line 3 are complex. The chosen comprehensive waterproofing solution after analysis is ground stabilization and waterproofing treatment for the tunnel boring machine entrance and arrival. The paper also details the construction technology, such as tunnel portal treatment, grouting control, and so on.
