The scale of high-speed rail network in Yangtze River Delta will exceed 5000 kilometers this year

On June 4, the reporter learned from China Railway Shanghai Bureau Group Co., Ltd that the Shanghai Suzhou Huzhou railway will be started in the near future. This is another landmark urban corridor carefully built by the Yangtze River Delta railway department through in-depth study and implementation of the spirit of the national two sessions, strengthening the construction of major projects, accelerating the improvement of the traffic network layout of the Yangtze River Delta ecological green integration development demonstration area.

According to the government work report, "we will focus on supporting the construction of" two new and one heavy "that not only promotes consumption and benefits the people's livelihood, but also adjusts the structure and increases the aftereffect," and increase the national railway construction capital by 100 billion yuan. ". "Two new and one heavy" is mainly to strengthen the construction of new infrastructure, new urbanization, transportation, water conservancy and other major projects. In the Yangtze River Delta, one of the main battlefields of railway construction in China, the annual infrastructure investment plan of China National Railway Group Co., Ltd. is 87.03 billion yuan, and the annual line opening is expected to exceed 1040 kilometers. Shanghai Bureau Group Co., Ltd. has a deep understanding of the important role of railway construction in the implementation of the "six stability" and "six guarantee" deployment, improving political position, strengthening responsibility, and Promoting Railway Construction with high standards, quality and efficiency. This year, the scale of the Yangtze River Delta high-speed rail network will exceed 5000 kilometers. Anhui will realize the city to city high-speed rail, and Jiangsu will realize the city to city bullet train. The "seamless" high-speed rail network will press the "fast forward" key to improve the regional integrated transportation service capacity.

We will continue to intervene in advance and concentrate our efforts to ensure the opening of the service in accordance with the law. Shanghai Bureau Group Co., Ltd. regards the high-quality early intervention as a hard indicator for the projects that must be opened within 8 years, such as the south section of Shanghe Hangzhou high speed railway, the first phase of Shanghai Tonghu railway, and the Wuxuan section of Anhui Jiangxi railway. From the "three dimensions" of advance, depth and comprehensive, it firmly pays attention to early intervention, and prepares the guidance manual for early intervention, joint commissioning and joint test by disciplines, with clear contents, standards and processes in list form To improve the quality of intervention in planning, design, construction, acceptance and other stages. The bureau group company scientifically and practically determines ten key points for intervention inspection of subgrade, bridge, track and other projects, organizes the preparation of "construction intervention manual" by disciplines, and refines the specific points of early intervention of seven disciplines one by one, so as to ensure that there are standards, key points and basis for early intervention of each discipline, eliminate the quality hidden dangers from the standard source, and eliminate the operation safety hidden dangers from the quality source. In order to ensure the high efficiency of early intervention, Shanghai Bureau Group Co., Ltd. has provided technical strength, carefully prepared plans, coordinated and promoted equipment defect correction, standard assessment, operation preparation and other work, and strengthened the organization of joint commissioning, joint test and trial operation. At present, the south section of Shanghe Hangzhou high speed railway and the first phase of Shanghai railway have successively entered the trial operation stage, so as to ensure that the operation conditions are available before June 30.

Pay close attention to the key links and ensure the construction in progress with high quality, high efficiency and order. Shanghai Bureau Group Co., Ltd. focuses on the current 17 projects under construction and projects to be started within 6 years, and strives to create high-quality projects. The group company of the Bureau deeply promotes the standardized management of commencement, strictly controls the "four gates" of design optimization, first article approval, equipment standard and quality acceptance, and controls the source of project quality; strengthens the management of quality and safety red line, strictly controls it with a "zero tolerance" attitude, and comprehensively applies early warning interview, economic assessment, credit evaluation, etc. to the units and employees who violate the law and touch the red line We have carried out 59 quality supervision and inspection and 8 batches of supervision and testing since this year. Shanghai Bureau Group Co., Ltd. has optimized the construction organization plan, scientifically allocated resources, and strengthened the management and control of quality, safety, construction period, investment, environmental protection and other system objectives. Since the second quarter, it has organized all participating units to overcome difficulties and resume production in an all-round way. In June, it is expected to complete an investment of 11.13 billion yuan, ensuring an investment of 34.56 billion yuan in the first half of the year. The investment plan will not drop year-on-year to ensure the completion of the project Fixed investment tasks and physical workload.

Explore and practice the deep integration of intelligent construction technology and construction management, and continuously improve the level of railway construction technology. Shanghai Bureau Group Co., Ltd. comprehensively promoted the application of railway engineering management platform, set up three-level construction management platform of bureau group company, project management organization and participating units, realized data collection, analysis, early warning and other management and control during project implementation, and improved construction management efficiency. The bureau group company strengthened key technology innovation, actively used sensors, UAVs and other terminal equipment, and promoted the application of Internet of things, mobile Internet and other information technologies in the construction of full section tunnel boring machine, drilling and blasting method and other large-scale machinery; highlighted key technology research, and grasped the complete set technology of kilometer level highway rail suspension bridge of Wufengshan Yangtze River Bridge, and the second phase of Shanghai Tong railway cross river shield tunnel Research on 9 major topics such as key technology of road construction, and innovate a batch of new technology and new construction methods for scientific management around signal, communication, fine adjustment of turnout, etc. Shanghai Bureau Group Co., Ltd. plays the role of operation and maintenance guarantee of intelligent construction technology in the whole life cycle management of the project, establishes the structural health monitoring system during the construction and operation and maintenance of large-scale passenger station in Hangzhou east railway station, and implements fault early warning; establishes the operation and maintenance management system of large-scale passenger station, and implements all-round integrated management of the land, real estate, energy consumption, patrol inspection, etc. in the station building.
