On June 27, as the shield machine's cutterhead rotated out of the tunnel and precisely entered the cradle, the left-line shield machine for the Wuhan Railway Station to Tiepuling Station section of Phase I of the Wuhan Metro Xingang Line was successfully received. This marks the **double-line breakthrough of the shield-driven section** of the line, and a new breakthrough in the project construction.

The section from Wuhan Railway Station to Tiepuling Station differs from other ordinary sections in that it is divided into three construction segments, including the shield-driven section, the cut-and-cover section, and the previously reserved section built together with Wuhan Railway Station. During the tunneling process, the shield machine had to continuously overcome four major challenges: passing alongside the existing Line 4 depot access tracks, passing beneath the Qinghua Interchange viaduct of the Third Ring Road, passing above the branch tunnel of the Baiyushan deep tunnel, and passing near a 110 kV high-voltage power line.

In response to the complex construction procedures, high difficulty, and high safety standards, Cheng Jiawei, the owner's representative of Wuhan Metro Co., Ltd., said that the project management team took the initiative, planned scientifically, and coordinated in advance, formulated emergency plans, and at the same time, drawing on the experience of the right-line shield crossing, set and adjusted relevant shield tunneling parameters, strengthened soil displacement monitoring and ground patrols through multiple measures, ensuring that the shield machine in this section accurately reached the shaft foundation pit of the Tiepuling cut-and-cover section and completed the receiving milestone.

As the first shield-driven section "work" of the line, the project department adhered to casting premium quality as the core, conducting daily technical analysis of segment elevation, centerline re-measurement, convergence deformation, advancement parameters, and segment assembly quality, promptly reviewing and adjusting in real time; strictly controlling segment entry, waterproofing inspection, and assembly acceptance, the tunnel's formed quality is good, with no leakage or deformation in the structure.

Phase I of the Xingang Line starts at Beiyangqiao Station and ends at Baiyushan Station. Phase I of the Xingang Line has a total length of 10.9 kilometers and consists of 5 underground stations, namely Beiyangqiao Station, Wuhan Railway Station, Tiepuling Station, Wanjiazui Station, and Baiyushan Station.

Xu Jianjun, a first-level project manager of Wuhan Metro Co., Ltd., said that after the completion of Phase I of the Xingang Line, it will help support key urban functional areas such as the Yangchunhu urban sub-center and the Beihu Industrial Ecological New City, strengthen the comprehensive transportation hub function of Wuhan Railway Station, increase the coverage of the rail network in eastern Wuhan, and improve the travel conditions of residents along the line.
