Metro Tunnelling
Metro Tunnelling
Underground Solutions Provider
With the growth of urban population and the acceleration of the urbanization process, the pressure on ground transportation is increasing, and the quality of the urban environment is gradually declining. As an efficient mode of public transportation, metro can transport a large number of passengers quickly and punctually, improve the transportation efficiency of urban traffic and relieve urban traffic congestion. Meanwhile, it can significantly reduce exhaust emissions, help improve the air quality of the city, and enhance the city's modernization level and international image.
As an equipment manufacturer that best understands construction and a comprehensive service provider that is most proficient in manufacturing, China Railway Engineering Equipment Group Co., Ltd. adheres to a customer-centered concept and is committed to providing customers with all-round comprehensive solutions. With the help of tunnel boring machines of different diameters, it can make tunnel construction under various geological conditions safer, better and faster.
Metro tunnel construction
Leading technology and expertise worldwide guarantee safety and efficiency of tunnel construction
Various CREG TBMs facilitate the construction of metro tunnels for urban traffic. In these projects, more than 3,000 kilometers of metro tunnel around the world have been constructed using the innovative tunnel boring technology of CREG. Based on solid professional knowledge and rich experience, CREG works closely with customers to develop tailor-made technical solutions to overcome all challenges and build robust tunnel structures while maximizing the safety of personnel and the urban environment as well as controlling budgets and schedules.
As the world's largest supplier of tunnel boring machines, CREG provides customers with products and services of the highest standards of technology and quality, combined with fast and comprehensive service. CREG pays special attention to teamwork and works hand in hand with all parties involved throughout the project.
CREG has completed more than 1,200 projects around the world in the fields of metro, road, railway, utility, hydropower and mines. CREG's tunnel boring technology is adaptable to all types of tunnels, pipelines, shafts in all geological conditions, with diameters ranging from 1 meter to 16 meters. Advanced technologies from CREG are used to build new infrastructure and help improve people's lives.
Full Range Services
CREG also provides high value-added customized services, including design, consultancy, tunnelling service, maintenance, remanufacturing, mechanical & electrical installation, technical service, spare parts, etc. CREG establishes remote support system for delivered TBMs to facilitate CREG rendering quick troubleshooting and real-time monitoring during tunneling.
Trend
The metro rail network increases its length by 325% between 2017 and 2050, to reach over 150,000 kilometres (Figure 3.6). China adds the most track length in absolute terms between 2017 and 2050 (about 43,000 kilometres), although the growth rate is higher in India (reaching close to 13,000 kilometres by 2050, up from roughly 1,000 kilometres in 2017). The balance of the global metro rail network shifts strongly towards Asia, where over two-thirds of all metro track-kilometres are to be found by 2050. Other regions where the length of metro systems is relatively low, including Africa, South America, North America and Russian Federation ("Russia"), more than triple or quadruple their metro network in the same timeframe. Europe and Japan, which already have large metro network coverage in their main cities, add almost 8,000 kilometres and 1,700 kilometres of tracks, respectively, providing almost 240 billion additional passenger-kilometres of transport per year, compared to 2017. In all world regions, the rate of train activity growth is faster than the track built-out; in the High Rail Scenario, the capacity utilisation rate of the metro network is improved by 40% (in terms of train-kilometre/track-kilometre) by 2050, with shorter intervals between trains enabled by digitalisation.
