Zhengzhou on the track, "zero distance transfer, seamless connection"

As the first rail transit PPP project in Zhengzhou, the first phase of line 3, which is operated and managed by CSCEC foundation on behalf of CSCEC group, is an important part of the strategic planning of Zhengzhou city to build "Zhengzhou on rail". It further improves the close connection between the four levels of public transport network of "fast, trunk, branch and micro" and rail transit, so as to realize the effective connection of aviation, railway, subway, public transport and taxi, and create various types It is a comprehensive transportation system with "zero distance transfer and seamless connection".

The line starts from the Provincial Sports Center in Huiji District in the north and ends at Haihang East Road Station in the south of Putian station of Longhai Railway in the north. It is a backbone rail transit line from northwest to Southeast in the central urban area of Zhengzhou. It is planned to realize passenger trial operation by the end of December 2020. It is estimated that after the completion and opening to traffic, it will take citizens only one hour to take subway line 3 from the provincial sports center station to Putian station of Longhai railway. Metro Line 3 has better promoted the radiation and driving role of Zhengzhou in the whole province, opened inter city bus linkage with surrounding cities, realized the sharing of resources in the field of public transport, market win-win, and formed the "1 + 4" metropolitan public transport system interconnection.

The most difficult subway construction process in Zhengzhou　

The planned construction period of the project is 3 years and 9 months. In order to ensure the epidemic prevention and control and return to work, the project headquarters of CSCEC foundation, CSCEC southern and Zhengzhou Metro Line 3 have set up a special supervision group to supervise the implementation of epidemic prevention and control and resumption of work; carry out the "three innovations and three bright" activities of Party members to promote the epidemic prevention and control and return to work under the guidance of the party building; and implement the "three zones" closed mode throughout the line Management, kill on time; "point to point" package special vehicles to ensure the safe return of more than 500 labor workers; timely carry out nucleic acid detection, organize more than 1200 nucleic acid detection, accelerate the personnel mobilization and screening; actively use information technology to carry out online office and training, and orderly promote the operation and evidence collection of operators in batches.

The efficient promotion of the project has been highly praised by the Zhengzhou municipal government. At the beginning of the resumption of work, Wu Fumin, vice mayor of Zhengzhou, led a team to investigate the construction site, fully affirmed the various measures for epidemic prevention and resumption of work, and highly appraised the achievements made since the commencement of the project.

The project passes through six urban areas and commercial intensive areas of Zhengzhou City, which has great difficulties in land acquisition and demolition, pipeline network migration and traffic guidance and transformation. It is the line with the largest number of preliminary works and the most difficult line of several lines constructed in the same period. Through actively promoting the standardization construction, the "four no" boutique tunnel with "no damage, no wrong platform, no leakage and no pollution" has been built, and 100% of the completed tunnel acceptance has been passed at one time, and has been promoted in the track project under construction of China construction foundation.

In the face of problems such as underpinning of Zhengzhou North Third Ring Interchange pile foundation, close underpass of existing Metro Line 1, shield tunneling under long-distance and small clear distance sewage main pipe, the project actively carried out scientific research project, obtained 9 provincial and ministerial level construction methods, 8 patents, 27 papers published, and was awarded by the Ministry of science and technology as a key special science and technology demonstration of "green building and building industrialization" national key R & D plan of "13th five year plan" by the Ministry of science and technology Engineering.

CSCEC will speed up the construction of Zhengzhou rail transit line 3 with high efficiency and maintain high-quality management.
