Following the breakthrough of the shield between Yucun South Road Station and Shitong Road Station of the first phase of Shijiazhuang Metro Line 4, recently, the left line shield between Shitong Road Station and Youyi South Street Station of the first phase of Line 4 was successfully launched.

In order to ensure the smooth tunneling of the shield construction, the Municipal Railway Group organized all units to formulate effective management and construction plans, and strictly controlled the installation and commissioning processes of the shield machine with high standards to ensure that the performance indicators of the shield machine met the requirements of tunneling. Before the shield starts, the starting end is reinforced, and the intelligent device is used to establish a remote information control system for the shield to monitor the construction early warning details, early warning settings, alarm confirmation push, background real-time monitoring, monitoring shield tunneling-related parameters and other information, so as to realize the intelligent tunneling of the interval. In the next step, the Municipal Rail Group will continue to boost its spirit, continue to do a good job in construction organization and planning, improve the level of construction management, promote the speed and efficiency of project construction with hard work and quick drying, and ensure the high-quality and efficient progress of project construction.
