Department of the Minjiang River flows through the two main rivers in Chengdu, Dujiangyan introduced a four river: cursory River, which flow to the formation of the Fu River and Nanhe River in Chengdu, Chengdu Fu River into the zone around the city, north, east and flow, Nanhe Loop West, River south to flow in the joint pavilion Department convergence. Later known as the Fu River confluence. Funan than 2300 years of history, gave Chengdu bring glory. But 60 years later, due to human and natural reasons, water quality gradually deteriorated, there is a limerick reads: "50's wash rice vegetables, water quality deterioration in the sixties, seventies fish peerless, 80 Seba's not removable tops. "Funan was first proposed 86 years of renovation, Longjiang Road Primary School a primary school, he wrote a letter to the mayor at the time that" I also Jinjiang water, "But then the city is building the Second Ring Road, no more human, material and financial resources to invest Funan, so from 87 years -92 years, conducted a five-year demonstration ,92-97-year period of five years, a total investment of 2.7 billion or so.
There are five of our Funan hidden risks for these five, we conducted five training works.
First, flood control works: low embankments, river siltation, river narrow, flood discharge capacity of serious shortage of capital cities in the nation worst flood control capacity, flood discharge capacity is 664 cubic meters / S, and the Po mouth of the bottle of water flow is 7 more than 100 cubic meters per second, meaning that if a flood occurred, not just by Po bottle of water can drown the fan-shaped alluvial plain of Chengdu, our new river bank 18 kilometers of this regulation, reinforcement embankment 23 km, 16 Amoy River km, new rebuilt 17 bridges across the river, five dams of 12 terminals, channel width of 30-80 meters from expanding to 40-120 meters, the flood capacity of up to 1299 cubic meters. Chengdu had a major disaster in a decade, every year a small disaster, but now once in flood control standard from ten years up to two hundred years, the original one to the flood season, the residents of the river at night should send a guard with the situation to beat a gong warning, moved with his family.
Second, environmental engineering: Funan River pollution is very serious, the original number of outfalls along the coast, more than 60 million tons of sewage discharged every day, there are 15 kinds of hazardous substances, coastal water pollution as a result of trees withered, abandoned wells, water shut down Residents living along the water, public toilets are also directly into the river contamination. Pollution first interception, we both within and outside the river, laying pipe, all the wastewater treatment plant closure into compliance after three watts into the river, some of the polluting factories along the river have also been moved.
3, Green Engineering: along the river should have been the easiest to create a green belt of the port, but no one residual tree management, fend for themselves, we opened a new green space green projects, the construction of a new opening into the spring and summer garden Four scenic winter.
4, road pipe network: the original is old-down pipeline, such as one that only a public toilet, a water pipe, often using the peak of a dispute, wires are overwhelmed, bought appliances are shelved, the road narrow, a The occurrence of fire, fire trucks can not open access, there is no gas pipeline, residents are using briquettes, the project built within the loop, the lateral expansion of the road and river channel, and will synchronize a variety of pipeline laid between the two, and laid the cable channel (embedded), so that no excavation of 50 years.
5, housing project residents, the residents had lived in dark, damp, crowded Diaojiaolou within the intrusive and often flood, cleanup, these 30000 people moved into the Second Ring Road 10, over 20 living in the surrounding Area, formed at the site on 687 acres of new commercial area and 860 acres of commercial and residential areas, residents expressed gratitude for giving the office more than 1000 comprehensive improvement of surface banners. The cost of the project up to a cost of 1.1 billion.
The total cost of 2.7 billion comprehensive improvement of our long-awaited: "Emerald Necklace" is about to form, this time in terms of international or domestic has a significant impact. Shanghai and Tianjin, 16 cities have sent a delegation to quiz reference.
