On October 30, 2024, in Huong Hoa, Tuyen Hoa District, Quang Binh Province, the second tunnel, with a length of 355 meters, under Package XL01 of the Khe Net Pass Railway Improvement Project, was officially excavated by the Ilsung-Deo Ca Joint Venture, two months ahead of schedule.
The Khe Net Pass Railway Improvement Project, part of the Hanoi – Ho Chi Minh City railway line, was launched on March 22, 2024. In May 2023, the Lonely Planet guide ranked the Hanoi – Ho Chi Minh City railway in Vietnam as the world’s most beautiful railway.
The project consists of two packages, XL-1 and XL-02. Package XL-01 involves the construction of two railway tunnels with a total length of 935 meters, to be completed in 23 months by the Ilsung-Deo Ca Joint Venture.
According to Deo Ca, the contractor has mobilized 230 engineers, workers, and machinery operators, along with over 35 specialized equipment, to work simultaneously on four fronts in the two tunnels. They have completed 130 meters out of 580 meters in Tunnel 1 and 355 meters out of 355 meters in Tunnel 2. The construction output has reached VND 120 billion, exceeding the planned progress by 9%.
Mr. Nguyen Duy Song, Director of Package XL01 Management Board, emphasized that the tunnel breakthrough on October 30 is a significant milestone, facilitating the transportation of fuel, goods, and workforce, thus accelerating the project progress.
Mr. Song also added that the NATM technology was applied in the construction of the Khe Net railway tunnels. Deo Ca has mastered and improved this technology, utilizing it in numerous road tunnel projects they have undertaken.
NATM (New Austrian Tunneling Method) is a globally popular underground construction method that offers flexibility in various geological conditions and enhances safety compared to traditional tunneling techniques.
The NATM process consists of ten steps, including marking the blasting area, blasting each tunnel face, clearing debris, installing steel mesh and spraying concrete, drilling holes for geo-technical anchors, applying a special fabric to waterproof the tunnel, pouring concrete for the tunnel shell and road foundation, among others.
Deo Ca shared that the Khe Net railway tunnels are unique as they run along the mountain slope, with thin cover and complex geology that differs from the initial technical design. To address this, the contractor has closely collaborated with the investor and supervision consultant, regularly monitoring the site and proposing appropriate reinforcement solutions to ensure safety and quality based on the actual geological conditions.
Additionally, the construction process faced challenges related to land handover, land lease for construction roads, and finding suitable waste disposal sites. To stay on schedule, the contractor proactively proposed construction solutions and enhanced internal training.
The targets set are to complete the excavation of Tunnel 1 before April 2025, finish the concrete shell and interior work of Tunnel 1 by November 2025, and complete Tunnel 2 by September 2025.
According to the Quang Binh Provincial Portal, the project’s completion will help reduce traffic congestion, enhance transportation capacity, boost socio-economic development in the region, strengthen inter-regional connections, and positively contribute to the National Transportation Network.
