en.Wedoany.com Reported - Recently, the "Kai Yuen" rectangular shield tunnel, part of the Yuen Long South Phase 1 Development Site Formation and Infrastructure project undertaken by China Road and Bridge Corporation Hong Kong Branch, was successfully completed. A breakthrough ceremony was held at the construction site. Several Hong Kong Legislative Council members, District Council members, Director of Civil Engineering and Development H Fong Shue-shing, Construction Industry Council Chairman Ir Ho On-shing, and Hong Kong Institution of Engineers President Ir Dr. Chow Kin-tak attended the ceremony to witness this tunnel breakthrough milestone.

At the ceremony, Mr. Fong Shue-shing commented on the high efficiency, safety management standards, cost-effectiveness, and shield machine design of the Yuen Long South project's rectangular shield tunnel breakthrough, and expressed recognition for the project construction team.

This tunnel breakthrough project involved undercrossing the heavily trafficked Yuen Long Highway, featuring shallow overburden, dense underground utilities, poor geological conditions, and a narrow working space. The project team adopted an innovative modular design for the rectangular shield machine, solving technical challenges related to transportation, lifting, and reception. The project simultaneously employed multiple monitoring technologies, including an automatic remote road settlement control system, ground-penetrating radar, and distributed acoustic fiber optic sensing technology. The tunnel breakthrough project was completed within one month.
