On July 5, as the cutterhead of the "Beyond No. 9" shield machine slowly rotated, the right-line shield of the Hong Kong-Macau Ferry Terminal Station to Jiaoyi Bay West Station shield-driven section of Section 2334 of Dongguan Rail Transit Line 2 successfully launched, marking the project's formal entry into the shield construction stage.

The Hong Kong-Macau Ferry Terminal Station to Jiaoyi Bay West Station shield-driven section runs along Binhaiwan Avenue. The right line of the section is 1,816.893 meters long and the left line is 1,820.108 meters long. The section is designed as a single-tube, single-track circular structure, with a line spacing of 15 meters and a minimum curve radius of 500 meters. The overburden thickness at the tunnel crown ranges from about 12.0 meters to 24.0 meters, and the strata traversed are mainly fully to strongly weathered mixed gneiss and moderately weathered layers.

Before launch, the project team deployed in advance and planned meticulously. In response to the complex geological conditions of the section, they invited experts for demonstration and guidance, discussed and formulated technical schemes, and ultimately selected an earth pressure balance shield machine with an excavation diameter of 6.98 meters. The main body of the shield machine is about 9.6 meters long, the overall length of the machine is about 100 meters, the total weight is about 600 tons, and the maximum thrust can reach 5,060 tons.

As an extension of the already operational Phase I and Phase II of Line 2, the Phase III project of Dongguan Rail Transit Line 2 starts from Humen Railway Station in the north and ends at Jiaoyi Bay Station in the south, with a total length of 17.1 kilometers. Upon completion, it will realize rail connection between the central area of Humen Town and the urban area of Dongguan and the Binhaiwan New Area, enhance the connection between Humen and the urban area and the Binhaiwan New Area, and, through transfer connections with planned Line 3, the planned Shenzhen Line 20, the planned Guangzhou Line 22, the Shenzhen-Jiangmen Railway, the Zhongnan-Humen Intercity Railway and other rail transit lines, powerfully promote Humen's deep integration into the Guangdong-Hong Kong-Macao Greater Bay Area.
