It is difficult to unify ideas and coordinate between units

Underground comprehensive pipeline corridors and sponge city construction are sustainable development concepts proposed in recent years and are in a stage of exploration and advancement in urban construction. Many places in China have insufficient understanding of the importance and urgency of sponge city construction, underground comprehensive pipe corridor construction and rectification of prominent sewage treatment problems. “I don’t know how to do it”, “Can I succeed the first time?” Many people ask this question. At present, the relevant national systems have not been perfected, and it is difficult for local governments to issue policies. Fear of difficulties has appeared in some places, resulting in insufficient quick action, insufficient implementation efforts, and insufficient methods and measures to solve difficulties and problems.

Take the underground comprehensive pipeline corridor as an example. The comprehensive pipeline corridor project has huge investment, and there is no guidance standard for the sharing of investment costs, and the construction standards are not unified. When constructing underground comprehensive pipeline corridors in some places, due to institutional reasons, most pipeline units are managed vertically. Local pipeline companies lack the right to speak, and it is difficult to coordinate work such as corridor entry and charging. Ideology and communication issues have become the first barrier to the construction of underground comprehensive pipe corridors and sponge cities.

Plans are difficult to formulate and projects are difficult to implement

Planning is the leader of construction and development. To build a city well, planning must come first. In many places, responsibilities for sponge city construction planning are unclear, and planning preparation is slow. The reporter learned that in cities that have completed planning and preparation of underground pipelines, the planning preparation standards are not high enough. Many urban underground comprehensive pipe gallery plans do not include all pipelines in the pipe gallery. Sponge city planning is not closely related to urban drainage and waterlogging prevention planning and underground comprehensive pipe gallery planning. Planning, etc. for effective connection. In the old urban areas of major cities, the construction of underground comprehensive pipe corridors and sponge cities is subject to land acquisition, demolition, relocation of existing pipelines, railway network, rail transit and other factors. It is difficult to select project paths and areas, and it is difficult to organize and implement them. Planning and implementation issues create a second barrier.

It is difficult to raise funds and it is difficult to operate PPPs

Public government expenditures in small and medium-sized cities are limited, making it very difficult to raise construction funds. Although the country has vigorously promoted the PPP model to build comprehensive underground pipe corridors and sponge city construction projects, and introduced a series of supporting policies, the PPP model has only been around for a short time in my country and there is a lack of successful cases. On the one hand, there is insufficient exploration and research on the PPP model, lack of experience, complex procedures, long operation cycles, and difficulty in operation; on the other hand, the PPP model is used to invest in construction, and social capital parties are unwilling to contact or invest, so they apply for policy bank special projects It is difficult to invest in construction with debt or credit funds. “It’s hard for a clever woman to make a meal without rice” is an appropriate description of the current predicament. Funding issues have also become the third barrier hindering the construction of underground comprehensive pipe corridors and sponge cities. In order to break these three barriers and strive to promote the construction of sponge cities and underground comprehensive pipe corridors, some areas in Hubei Province have taken the initiative and made active explorations. For example, Wuhan City started construction of 40 kilometers of underground comprehensive pipeline corridors in 2016, and determined the third phase of Tianhe Airport, Wuhan Central Business District, East Lake High-tech Optics Valley Central City, East Lake Wujiashan New City, Caidian Sino-French Ecological New City, Economic and Technological Development There are 6 comprehensive pipe corridor projects on Zhushan Road in the district; Huangshi Garden Expo project, the park simultaneously implements rainwater utilization technology and green space landscape, through permeable paving, setting up grass planting trenches, soil cover greening, sunken green space and other measures and design means The "sponge" concept.

All localities need to fully understand the necessity of promoting the construction of underground comprehensive pipe corridors and sponge cities; in accordance with the "Guiding Opinions of the General Office of the State Council on Promoting the Construction of Comprehensive Pipe Corridors in Urban Construction" and "The General Office of the State Council on Promoting the Construction of Sponge Cities" "Guidance Opinions" and other documents, combine the urban master plan to coordinate the above and below ground, speed up the planning preparation from a high starting point; in terms of fund operation, we must innovate the investment model, actively use the government and social capital cooperation model, and actively strive for national policy funds and project special funds Support; in the process of accelerating the construction progress, we must firmly establish quality awareness and conscientiously implement the main responsibilities of all parties such as construction, construction, and design supervision to ensure project quality. Let the construction of underground comprehensive pipe corridors and sponge cities benefit the people as soon as possible.
