 Recently, the Academy of Municipal Services won the tender for the EPC project of Qingfeng Road (Nanxi East road-luli Street) tunnel construction in Jiaxing. Hing Fung road tunnel is a 769m long tunnel with vehicular, non-vehicular and pedestrian access in Nanhu District Jiaxing. This project is an important passage connecting the green wedge in the northeastern city of Jiaxing with the sub-center of the southeast city. It is also an important component of the passage connecting Jiaxing Station with Jiaxing South Station, and a key project of the 100th anniversary of the founding of the Jiaxing Party. The winning bid of this project is the result of many years'innovative research and market development in the fields of sponge, green and smart city. In the design of this project, the design team of the institute will apply four innovative technologies to practice, and strive to create a "green, ecological, intelligent" tunnel. Tunnel spongification. Based on the mathematical model of drainage basin and the mathematical model of tunnel catchment zoning, the flood risk of the tunnel under the situation of one-hundred-year flood and one-hundred-year rainfall superimposed is simulated and analyzed systematically, and a systematic solution is proposed. The tunnel is located in an ecologically sensitive area such as Nanhu Lake. Based on sponge practices in Jiaxing and Shanghai, the project itself uses an upgraded sponge city SPONSMEDI 2.0 technology system to minimize the impact on hydrology and ecosystems, the total annual runoff and pollution control rate are both over 80% . Resource Utilization of residue soil. In view of the characteristics of high water content in the slag soil of the Jiaxing Tunnel project, the technical system for the utilization of the slag soil resources developed by the institute and successfully applied in Shanghai and Nanjing is adopted, with Shenhuan Company Independent Intellectual Property Nowasmedi series of high-performance environmental curing agent, can achieve 70,000 cubic meters of engineering waste soil into treasure. Tunnel intelligence. Qingfeng road tunnel in the design, construction and operation and maintenance management of Research Institute Research and development of Integrated Pole facilities information model integrated design system, combined with intelligent lamp, Internet of things technology, to provide intensive data sharing services, it can realize all-round security and intelligent management of tunnel, such as tunnel safety, tunnel operation environment, tunnel traffic and pedestrian, and realize multi-dimensional management visualization, monitoring integration, maintenance intelligence and perfect emergency system. Structural intensification. Through the application of the patent "one kind of underground structure roof waterproof layer protection structure" , the depth of the tunnel roof soil is reduced, the tunnel longitudinal slope is greatly reduced, not only the riding and walking through the tunnel, but also the construction cost is reduced, reduce the social cost of operation, increase the social benefits of the project, fully reflect the concept of "Green Tunnel" . At the same time, the pipeline crossing the river skillfully combined with the tunnel comprehensive pipe gallery for intensive laying, saving underground space.
