Background technology
China's Municipal public utilities adhere to different unit construction and management separately, since building time is successively different, and
Unified planning and comprehensive utilization are not carried out to urban underground space.Underground pipe network construction mostly uses the city planting ductwork of traditional direct-burried
Engineering construction mode, various municipal pipelines are mostly directly embedded in soil layer by respective system, and maintenance is inconvenient, is easily damaged,
The ability of securing an adequate supply is often subject to interfere.Since the depth of burying of various pipelines differs, it is be easy to cause conflict, urban road is frequent
It is destroyed.Road surface is excavated repeatedly causes route denial, traffic jam, road surface patch pile patch.With urban development, buried pipe
Line is increasingly complicated, deep-rooted, is formed " underground noodles problem ".Subway work, which also increases because of relocation of services or temporary shift, to be built
Being set as this, even initiation resident is discontented.Pipe network facilities increase or repair, the building site of urban construction also can be found everywhere, and such as coal gas changes
Natural gas, laying communications optical cable, embedded cable power transmission, water supply network repairing, gas piping repairing etc..Many urban pavements also like
Slide fastener is the same constantly to be excavated, fills.It is straight caused by the pipe network accidents that the whole nation is caused by construction every year according to incompletely statistics
Economic loss is connect up to 5,000,000,000 yuan, indirect economic loss is up to as many as 40,000,000,000 yuan.
Underground pipe gallery is also known as " common trench ", the various pipeline collection such as electric power, communication, combustion gas, water supply, draining, heating power
In one, an intensive tunnel is built in the underground space of urban road.Underground pipe gallery makes space utilization more fill
Divide, is compact, economical, also allowing for overhauling, more will not turn off road breaking face because of the old pipe of maintenance, the new pipe of the row of applying.State Council in 2014
