Recently, the right-line shield tunneling of the section from Yishan Road Station to Nanzhu Bridge Station of the first phase of Tianjin Metro Line 8 was successfully completed. This section is located on the third underground level of Nanzhu Bridge Station, where the construction environment is complex and the technical requirements are high. During construction, the project team, through scientific and reasonable planning, effectively coordinated key processes such as portal breaking, removal of freezing pipes, mortar backfilling, and precise advancement of the shield machine, ensuring seamless connection of all stages. At the same time, the construction team strictly monitored the tunneling parameters to ensure construction precision and safety, effectively avoided impacts on the surrounding environment, and safeguarded the normal operation of Nanzhu Bridge and its surrounding businesses.
