Nanjing City Hall recently issued "on the establishment of long-term mechanism of city management advice", including provisions to strictly implement the "build a new road in five years not excavation" requirements, the implementation of the road on the annual need of excavation in early planning, step-by-step implementation way, check to be strict examination and approval. The annual total excavation road and synchronous excavation area ratio of rigid index, and community publicity, strict control of road excavation behavior, reduce the construction people. ("Yangzi Evening News" June 4th)

lives in the city, I am afraid no one without a "zipper road". In 2009, Qingdao had 487 road excavation, individual roads also appeared within 8 months of continuous excavation 3 times. Although this case may seem extreme, a similar phenomenon is not unique to Qingdao. To deal with the "zipper road", many city issued "regulations 3 to 5 years not to repeat the excavation", but in fact it is difficult to be thoroughly implemented, "ban" does not have "deterrent".

Nanjing introduced the "road excavation must be public", although more humane, also know how to respect the will of the people, but can not really solve the "zipper road" pain? After all, "publicity" is not cut, but more of a "public opinion", people have no right to powerless to stop.

Cause

"zipper road" waste not know, be shocked. According to estimates, road construction and leads to the excavation damaged part of the facilities fees: 300 yuan per square metre of asphalt pavement, cement concrete pavement per square meter to 170 to 200 yuan...... Add Cheap Throwback Oilers Jerseys up and so on, city road every 1 meters million spent on. Cheap Throwback Cowboys Jerseys The cost of this year will rise. In addition to Cheap Throwback Bills Jerseys just cost, and the cost is not clear, including the construction of pollution, safety, traffic congestion, vehicle fuel consumption, pedestrian delay error costs, more heavy invisible cost is the loss of government reputation.

to solve the "zipper road", by a few "ban" or "opinions", certainly, also need a technical effort. It is understood, now the best technical solution is to build "trench", namely the city underground pipeline corridor. This refers to the set on the ground, underground or overhead all kinds of public pipeline concentrated accommodated in one, and leave for maintenance personnel walking tunnel channel. Is the construction of a tunnel in the city underground space, the municipal, Cheap Throwback Raiders Jerseys power, communications, gas, water supply and drainage pipeline in one set, a manhole, the hoisting orifice and monitoring system, the implementation Cheap Throwback Eagles Jerseys of unified planning, design, construction and management in the past, their respective pipe construction, management of the messy situation completely changed. The line opened, only need to notify the relevant responsible departments, switch on the interface, is easy to repair, and save the national resources.

developed many years ago began construction "trench", such as Japan, in 1963 promulgated the "common pipe trench" implementation method, solves the key problem of capital allocation and recovery of joint pipe, ditch construction technology, and with the development of city construction repeatedly revised perfect. At present domestic only Beijing, Shanghai, Shenzhen, Suzhou.
