The earth pressure balance shield tunneling machine developed by China Railway Construction Corporation Limited was officially launched on May 6th, marking another important milestone for the company in the Santiago Metro Line 7 project in the Chilean capital. This innovative device will assist in the smooth progress of the project.

On the morning of the departure ceremony, it was held in Renca, the capital region of Chile. Chilean Minister of Transport and Telecommunications, Munios, presided over the ceremony and unveiled the name of the shield machine as the Matucana.

During an interview with reporters at the event, Mu ñ oz said that the Chilean government hopes to improve people's quality of life through sustainable means. Introducing advanced foreign technology is an important path to achieve this goal, just as this Chinese made shield machine was transported across the Pacific to Chile and used in a subway project for cooperation between enterprises in Chile and China.

This project is the first subway construction in Chile to use shield tunneling machines. According to China Railway Construction Corporation, the shield tunneling machine has a total length of 105 meters and an excavation diameter of about 9.8 meters. It has advantages such as fast excavation speed, strong turning ability, wide adaptability to geological ranges, and minimal impact on ground transportation and residential life. Keywords: overseas engineering, international engineering construction, foreign engineering construction news.

CRCCsuccessfully won the bid for Section 1 of the Santiago Metro Line 7 in 2021, with a total length of 7.9 kilometers, including approximately 6.6 kilometers of shield tunneling. According to data provided by the Santiago Metro Company in Chile, the entire Line 7 is 26 kilometers long and will pass through 8 cities in the capital region. After completion, it is expected that the entire operation time of the line will be shortened to 37 minutes, greatly reducing the transportation time between the two terminal stations, and it is expected to bring convenience and well-being to about 1.6 million residents along the line.
