since the beginning of this year, the upstream of the Hanjiang River water than the historical average reduction of 80%. Affected by this, the lower reaches of the Hanjiang River East Jing River almost cutoff, Zhanghe reservoir is located in the stagnant water under, about 6000000 acres of crops is facing a severe drought in Jianghan plain.
in order to alleviate the severe drought, water diversion engineering concern today will be the emergency water diversion and drought resistance, 51 days earlier than the original water time.
reporter yesterday in the South North Water Diversion Project site, now 8, control gate opened, the Yangtze River water will flow to 100 cubic meters per second to the middle and lower reaches of Hanjiang River, and finally from the high stone town Qianjiang city Xinglong section of Hanjiang River to Hanjiang River, along the Cheap Nationals jerseys about 6000000 acres of farmland moisture.
51 days in advance through the water, how to ensure the engineering safety? In this regard, Water Diversion Engineering Bureau, the inlet and the outlet of the 400000 party mud, into the estuary of the cofferdam, and the water level of flood control brake gap, are the three big problems stopped in the emergency of the waterway. As of yesterday afternoon, three problems solved, and laid a solid foundation for today's water diversion.
6 day of uninterrupted job
cofferdam has removed
3 pointyesterday afternoon, the reporters came to Shiqiao River junction. Standing in the water diversion canal side project, the reporter saw, the Three Gorges dam water discharged is very clear. Water diversion project to emergency water diversion, first of all to overcome difficulties, is the main water inlet cofferdam and earthwork removed. Not the cofferdam and earthwork removed, flow into the canal river is very difficult to stable.
reporter saw, the earth cofferdam has been removed, the three dredger operating under tension, in main canal, an engineering vehicle is erect conduit.
Water Diversion Engineering Bureau, a vessel, every day can dig 10000 square earth, inlet section at present in Qianjiang clay has basically cleared, but the water under the earth has not yet finished digging, but not for today's emergency water diversion is hindered, the water flow rate can reach Cheap Rockies Jerseys 100 to 150 cubic meters per second. The pipeline is currently set up is used to clean and dredge to dig in the soil. The 6 Cheap women mlb jerseys km long pipeline. Underwater mud by dredger dredging, through the pipeline to the special field 6 kilometers outside the processing.
it is understood that after 6 days of continuous operation, the cofferdam into the estuary has been completely dismantled.
exit gate 3 days ahead of schedule to open
reduces the gate level flood drop
trunk doesn't extend to 500 meters, is the Shiqiao River sluice. Emergency water diversion second difficult is the sluice. Sluice, a total of five gate hole, open a Cheap World Series Jerseys few gate determines the water transfer smoothly or not. Stand in the gate of Yangtze River water level on the river and canal, the completely flat, but the water level and control gate within Cheap Rangers jerseys 5 meters of the gap is still.
