the Ji'nan times
rolling east of the Yangtze River, and now in Jiangdu, Yangzhou, a bend is turned north.
in May 30th, the Jiangsu section of the eastern route of the south to North Water Diversion Project, which lasted for 11 years, tried to pass water, and the Yangtze river ran towards the north along the Millennium canal. According to the water diversion plan for the south to North Water Diversion Project, the eastern part of the third quarter of this year will achieve comprehensive water diversion.
since June 2nd, the reporter has followed the footsteps of Changjiang River and walked back to Shandong, allowing Ji'nan citizens to feel the road of the Yangtze River water before meeting the water of the Yangtze River.
the reporter visited the source of the East Route of the South-North Water Transfer Project, the source of the Jiangdu water conservancy project,
the east of the Yangtze River "turning" to the North
the source of the Yangtze River Hub project management office, a stone tablet engraved with "source" two words. This is the starting point for the eastern route of the south to North Water Diversion Project.
Jiangdu water conservancy project is located in Jiangdu District, 14 kilometers east of Yangzhou, and 4 power pumping stations are the "heart" here, and dozens of pump station units can be pumped from the Yangtze tributary. This trial is responsible for pumping third and fourth pumping stations. The reporter heard that the machine was roaring in the pumping station of No. 3 pumping station, but the Yangtze River water outside the pumping station could not see the wave surging but quietly flowing.
in fact, when the water starts to flow, the wave is very spectacular, but once it works, the water surface is steady. The management office staff said that after preliminary design, smooth flow is the result they most expect to see.
after this pumping station, the Yangtze River water has risen 7 meters.
reporters saw that the Yangtze River water through the pumping station slowly remitted to the high water river on the other side. The river of Gao Shui River is broad, all the way north, and then into the Grande Canale, Beijing and Hangzhou.
the water of the Changjiang River embarked on the journey. After the arrival of East Pinghu, the "
high point" can be
the Yangtze River water is starting from Jiangdu, and the land to the north is getting higher and higher. To smooth northward, the 13 cascade pumping stations are like "Hercules", lifting the Yangtze River Water step by step until they are sent to East Pinghu.
the pumping station unit at the source runs at high speed, pumping the water from the main stream near the Sanjiang camp near Jiangdu to the pump and then sending it to the other side. Pumping station equipment will also block the river and prevent its backflow. The reporter learned that there are 9 Jiangsu stages in the 13 cascade pumping stations. 13 cascade pumping stations connect lakes in Hongze lake, Loma lake, Nansi Lake and Dongping lake. When the Changjiang River reaches East Pinghu, the terrain can reach 65 meters, and then the Yangtze River flows to Tianjin and Shandong.
staff of the management department said that in Jiangsu, the 2 pumping stations in Jiangdu and Baoying in Yangzhou are a cascade, the Jiangdu Railway Station in Yangzhou is responsible for the drainage of Changjiang River, and the Baoying station is replenish from the Lijiang River to provide multiple guarantees for water transfer. The water of the Yangtze River realizes the North flow, and the work of the pump station can not be ignored.
water diversion should be adjusted to see the north "thirst no thirst"
June 2nd, the reporter saw in the Jiangdu water conservancy hub, only 2 of the pumping stations. This is not surprising, according to the staff, pumping stations are not water diversion throughout the year, whether the diversion of water should be taken into consideration in the north, "thirst is not thirsty." "Now that the North has entered the flood season, there will be more rainfall and may not need too much water from the Yangtze River. Less precipitation in winter may require more water. " Mr. Shaw, who has been working for many years at the hub, said that the rainy season in the south is coming soon, and that too much water can not be pumped into the river to prevent the emergence of heavy rainfall, and it will bring danger to the residents and villages in the lower reaches of the river.
reporters learned that according to the designed flow, Jiangdu pumping station can draw 500 cubic meters per second, and lead the Changjiang River to the north. However, at present, the north is not thirsty, and the south to North Water Diversion Project has not realized the whole line of water, so no pumping stations have been started. Even if the eastern line is running across the river, the Yangtze River water will adjust the water volume at any time according to the needs of the north. In this way, the energy consumption can be reduced to the maximum extent and the utilization of water resources will be more reasonable.
water diversion from the Yangtze River to the source of Jiangdu will have an impact?
reporter learned that the water pumping amount of the Changjiang River in the south to north water diversion is 500 cubic meters per second, and the water quantity of the Yangtze River can reach more than 10000 cubic meters per second, so the water level in the Jiangdu section of Yangzhou is very small.
to realize the water of the Changjiang River, it will not be used for production and life, but in the lakes along the way, such as Lake Luo Ma, Nanhu and so on, waiting to be opened quietly.
North
residents drink long river water is a bit difficult
talk about Changjiang water, many Yangzhou people are proud of themselves. Even the taxi Master said that sending the Yangtze River to the north is a good thing for the northern residents. In their view, the water of the Yangtze River has a better drink.
in fact, according to the reporter, the Yangtze River water to the north, it is also difficult to supply the residents exclusively for drinking. The Yangtze River water is likely to be mixed with the Yellow River water to provide domestic water for residents or for the production of enterprises.
more than 1000 kilometers from the south to the north, can the water quality guarantee the water quality? The reporter learned that after the Jiangsu section was tested through water, the water quality was strictly tested and the water quality requirements of three types of surface water must be reached. According to conservative estimates, the number of beneficiaries in the eastern route will exceed 100 million.
according to the plan, 1 billion 500 million cubic meters of water can be transferred to Shandong every year, and the water consumption in Shandong, including Ji'nan, will be more secure.
let the river water flow back, let the south water to the north, follow the nature, love the nature, and let nature serve us - all this can start from Jiangdu, Yangzhou.
