| At present, most of the municipal buried pipelines are taken the way of direct burial; therefore, roads have to be"broken belly cut open"when we maintain pipelines. In this way, not only wasted human, financial, material, but also blocked the traffic, destroyed the environment.Utility trench as an intensive facilities pipeline can solve the problem very well. Utility trench refers to set in roads, be used to hold more than two utilities or municipal pipelines and affiliated equipments, and it has a special reconstruction system of repairing, lifting and monitoring. These advantages are: 1) to ensure to give full play to the functions of the road traffic; 2) to fully utilize roads; 3) to ensure safety and stability of the lifeline; 4) to protect the urban environment; 5) to enhance the abilities of urban disaster prevention and anti-disaster. According to the Hanshin earthquake in Japan, building utility trench has avoided the occurrence of secondary hazards.The real estate board of Qinhuangdao city will implement"88918"project in 2009. It will vigorously promote 8 projects of indemnificatory housing, 8 reconstruction projects of"villages in city", 9 reconstruction projects of old residential districts, and 18 improvement projects of old residential districts. On this occasion, I suggest to contribute utility trench to provide the possibilities of sustainable development of city infrastructure.Due to the utility trench has more than 100 years history, after years of practice and study, utility trench construction technical level has been greatly matured, and got a full practice in the world. In my paper, I only to study the social benefits, The formulation of laws and regulations and Management of attribution, investment and financing ways and operation mode of constructing utility trench . On the social benefits,first,utility tunnel infrastructure construction is the embodiment of sustainable development, In 1996, China had "sustainable development" as the country's basic development strategy, Both from economic growth,Social progress and environmental security objectives of the utilitarian, Also from a philosophical concept of renewal and progress of human civilization rational goal,All-round coverage of the "population, resources, environment, development" of the dialectical relationship between the four-in-one,And such relations in different regions during different time periods and differences,Integration throughout the development and evolution of the common trends among .A result of the development trend of urbanization, Cities and sustainable development is the focus of sustainable human development and focus, Sustainable development in urban infrastructure development should be used as part of the first, Therefore, I propose the construction of the utility tunnel, Tunnel design life span of 50-75 years in general, And has not been installed for the pipeline and line set aside space, Ensured the possibility of sustainable urban development. Second, Service-oriented government in the construction, Now urge the Government to "all government" to "limited government",A change in government in direct control of production, exchange and distribution of each link, A virtual monopoly on the allocation of resources, income distribution, such as the status of all functions, Positioning of government functions will be policy makers in order to maintain, institutional innovation, social integration, etc., Adhere to compensate for "market failure" of the principle of complementarity, In order to achieve the market functions and the coordination of government functions. Service-oriented government as a people-based government, Is to serve as the fundamental mission of government, And is based on the provision of public goods and public service mission of the Government, Listen to the voice of the people, Would like to think the masses of the people, anxious people of the masses, Effectively to serve the people as a top priority, Call for the people of the "road zipper" problem, How to deal with as a matter of concern to the public, Street if the road construction in the main channel as a common solution to this problem, Their hands above their heads is no doubt in favor of the people, but also service-oriented government really think for the people, service to the people the direct embodiment. In the policies and regulations, From abroad and the development of China's Taiwan region the practical experience of the utility tunnel can be seen, sound laws and regulations is to develop the protection of the utility tunnel, Although some of our cities and regions to develop a utility tunnel -building laws and regulations, but its feasibility has yet to be improved, Should be considered co-channel investment, management, construction, operation mode of the various aspects of the development of laws and regulations, and to a certain extent feasible.The right of ownership in the management of, Our pipeline is a variety of municipal policies in a number of doors, under the coordination difficulties, The absence of a unified management of the sector, which has made renovation plans can not be unified, Led to a "road zipper" phenomenon continues to occur, Japan in 1991 set up a special co-channel management, and responsible for promoting the construction of the utility tunnel, the joint was able to ditch the fast-growing. Sixth of China's ongoing reform of government institutions for the settlement of this issue possible. For example, in Changchun City in the reform of government agencies set up a "Council of the City of Changchun Public Authority", Urban and Rural Construction Committee and the municipal infrastructure maintenance, road maintenance, fuel (coal) gas management, urban water management responsibilities, city real estate management and housing of the urban heating Security management responsibilities, integrated into the municipal utility board. After the reform of the municipal utility board can be used as a utility tunnel on the administrative departments, and circumstances in accordance with the law, you can promote the development of the utility tunnel. In investment and financing modes, respectively, commonly used to introduce foreign PPP mode and the BOT model, And China has built some of the unit cost of the utility tunnel for the statistics, utility tunnel as quasi-public goods is still very large investment, the Government's financial investment alone can not meet their construction, This only requires the use of public-private partnership approach to building a utility tunnel, but there are also shortcomings, For example, the utility tunnel as municipal infrastructure, the city served as the "lifeline" of the important role of, By private persons or enterprises involved in construction, management, security for the protection of the city must also have hidden dangers, which requires, in the formulation of the implementation of public-private partnership program, it is necessary to consider all aspects of co-ordination, effective protection of the Government in the utility tunnel on the management, supervision status.The way in the operation, Basically divided into three models, the Government is solely responsible for the system, the pipeline unit rental system, the Government and the pipeline unit to share system. From a security point of view of the government solely responsible for the system is the best option, but the financial pressure on the government too much. The remaining two models are in varying degrees, will bring a certain degree of risk, asking the Government to give full play to its inspection and supervision functions. At the same time, also in this part of the model of cost-sharing analysis, and specific applications in the analysis of the city of Qinhuangdao.Finally, transformation of East and West Baita Ridge as an example of community analysis and application specific. |
