On the morning of April 21, the shield machine for the right line of the Machangdao Station to Renmin Park Station section of Phase I of the Tianjin Metro Line 8 project was officially launched, marking the project's entry into a new stage of construction. It is reported that the right line is 786.627 m long in total, with complex geology and high water content. To effectively reduce construction risks, the shield launch adopted a steel sleeve launching process, and the soil reinforcement adopted vertical freezing reinforcement technology, with parameters adjusted through real-time monitoring data to ensure construction continuity. During construction, the project team organized scientifically and arranged reasonably, continuously optimizing the construction plan and strictly implementing acceptance procedures to ensure smooth construction.
