Baoshan Urban Construction: Put an end to “zipper roads” and say goodbye to “spider webs”

For a long time, urban construction has been "emphasis on the ground and light on the underground". During the construction of urban roads, the supporting construction of the underground pipe network was not considered as a whole at once. As a result, urban roads were repeatedly "unzipped" after they were completed, which not only caused It is a huge waste, affecting the appearance of the city and the quality of roads, and also seriously affecting the quality of life of the people.

In order to solve this development problem, Baoshan City has boldly explored and piloted in recent years, and vigorously promoted the reform of the construction methods, operation models and management systems of underground comprehensive pipe corridors in central cities .

Since 2013, Baoshan City has conducted a comprehensive review of the current status of underground pipelines and hydrogeological conditions when renovating Yongchang Road and constructing major urban roads such as Baoxiu Road and Qingbao Road. Detailed research and assessment, comprehensive survey and analysis of surrounding land use, pipeline load connection, etc., put forward ideas for reforming urban construction. Combined with the actual conditions of different factors such as traffic flow, pipeline capacity, service scope, water system intersection, road slope, and surrounding buildings, the layout of underground pipelines will be considered as a whole, and single-warehouse, three-warehouse, and double-warehouse comprehensive pipeline corridors will be built under the road to connect strong and weak current, Water supply, gray water, gas, sewage, communications, radio and television and other pipelines are included in the pipeline corridor, which effectively promotes new urbanization, improves people's livelihood, fundamentally solves the problems of repeated excavation and repeated investment in urban roads, and effectively promotes New urbanization construction.

"In order to do a good job in municipal infrastructure, mainly pipe corridors, during the construction process, there must be systematic planning to properly solve the 'construction' problems and support the subsequent 'management'. ' problem." According to the relevant person in charge of Baoshan City, in accordance with the requirements of "multiple plans into one", Baoshan combines national economic and social development planning, urban and rural planning, land use planning, ecological environment protection planning, woodland use planning, and water resource utilization and protection. Planning, comprehensive transportation development planning and other "multi-plans" organically connect professional plans such as electricity, water supply and drainage, gas, communications, etc., forming a comprehensive urban planning system. On this basis, the "Baoshan Central City Underground Comprehensive Pipe Corridor Special Plan" was scientifically formulated 》, rationally arrange construction projects and implementation timing, and improve the integrity and systematicness of municipal infrastructure.

There is a huge demand for funds for the construction of underground comprehensive pipe corridors, with an average investment of 74.394 million yuan per kilometer. Therefore, to implement project planning, funding is the primary problem that must be solved.

In the process of exploration, Baoshan City changed the old concept of relying on government investment for urban infrastructure construction and adopted a socialized and diversified investment and financing model to solve the problem of construction funds. Baoshan Changyuan Water Company was jointly established by the municipal state-owned enterprises Yongchang Investment Company, Municipal Electric Power Company, and Longyang District State-owned Assets Company to build a financing platform and raise construction capital from bank financing through corporate operations. At the same time, the PPP model was adopted for construction. With the authorization of the municipal government, Baoshan Changyuan Water Company held 40% of the shares and social investors held 60% of the shares. *** jointly funded the establishment of a project company to be responsible for the investment, construction, operation and management of the project. For maintenance, the municipal government grants the project company a 30-year franchise. After the concession period, the project company will hand over the project assets to the government free of charge.

The completion of the pipe gallery construction is the "hardware" part, and putting it into operation is the focus and ultimate goal. In order to ensure that the entrance to the corridor is in place, Baoshan City has reasonably determined specific measures to guide the entrance to the corridor based on in-depth research. With the approach of "policy + administration + coordination", various pipelines are guided to actively enter the corridor. Pipeline units have gradually evolved from not understanding to gradually understanding, from avoiding to taking the initiative to study, from finding reasons to exclude to universal recognition, and basically formed the corridor entry** *knowledge. Up to now, Baoshan City’s Yongchang Road, Qingbao Road, Baoxiu East Road, and Lancheng Road comprehensive pipeline gallery has been put into operation, with a length of 23.76 kilometers and a total of 152.6 kilometers of pipelines in the corridor.

“With the continuous expansion of urban space and the integrated development of urban and rural areas, it is a common phenomenon that municipal infrastructure debt is in debt. This requires the integration of integrated pipe corridors and Other municipal facilities are regarded as the "shortcomings" that need to be filled in urban development, and are regarded as the main measures to solve urban problems such as only rebuilding without paying attention to management, focusing only on the above ground but not on the underground.

"Industry experts believe that the construction of comprehensive pipe corridors can play a better role in controlling road zippers, aerial spider webs, black and smelly water bodies, and urban rainwater and sewage diversion.

Reduce the ups and downs The phenomenon of excavation allows underground space to be developed rationally, making it easier for people to go out, and provides new impetus for regional economic development... In practice, the construction model of underground comprehensive pipe corridors in Baoshan Central City has been widely recognized.

In May 2016, Baoshan City passed a competitive review and became one of the 15 pilot cities for underground comprehensive pipe corridors in the country, providing a demonstration for how to promote the construction of underground comprehensive pipe corridors in the economically underdeveloped western regions. . In October of the same year, the Baoshan City Underground Comprehensive Pipeline PPP Project was included in the third batch of national PPP demonstration projects by the Ministry of Housing and Urban-Rural Development and the Ministry of Finance in 2017. Baoshan received 97 points and 94 points respectively, ranking first in the country. In the forefront. In the list of winners of the 2017 China Human Settlements Environment Award announced by the Ministry of Housing and Urban-Rural Development in October of the same year, the Baoshan City Center Urban Underground Comprehensive Pipe Gallery Construction Project was listed on the Chinese list for its important role in improving the urban living environment of Baoshan City.
