Recently, good news came from the L2-N3 tunnel, the main tunnel of The Line, in NEOM New City, Tabuk Province, Saudi Arabia. The L2-N3 tunnel was constructed by China Construction Middle East and China Construction Sixth Engineering Bureau, and the complete set of tunnel drilling and blasting construction equipment of China Railway Construction Heavy Industry Co., Ltd. participated in the construction. The single-month footage record of the N3 tunnel has been refreshed. The single-month footage record of the main tunnel of the project has been refreshed to 185 meters per month, and the single-cycle footage record has been refreshed to 5.93 meters.
Because the temperature in the project site exceeds 40°C all year round, the temperature difference between day and night is large, the climate is dry and sandy all year round, the instantaneous rainfall in the rainy season is large, and the humidity changes greatly, the construction organization is difficult. The extremely harsh environment also places extremely strict requirements on large-scale mechanized equipment. More than half of the tunnel construction equipment for the project was provided by China Railway Construction Heavy Industry, including fully computerized three-arm rock drilling rigs, concrete wet spraying rigs, arch trolleys, and anchor trolleys. and concrete mixing stations, etc.

China Railway Construction Heavy Industry has developed the ME series Middle East version of the tunnel drilling and blasting construction complete set of equipment in response to the extreme high temperature, high humidity, strong sandstorms, and large temperature and humidity changes on site in the Middle East. After being used in multiple projects in the United Arab Emirates, Saudi Arabia and other regions, the ME series Middle East version of tunnel drilling and blasting construction equipment has demonstrated strong product capabilities.
Railway Construction Heavy Industry provides customers with customizable products and full life cycle services. The products have low failure rates, high construction efficiency, and strong adaptability to working conditions. They are more suitable for construction in the Middle East and similar extremely harsh working conditions.
According to statistics, at present, the average monthly footage of Chinese contractors in each work area is about 25% faster than that of foreign contractors, and the reliability of construction equipment is 9% higher.
