'LuDian 2014 earthquake in the bullpen Jiang Hong rock formed two big lake diaphragm wall construction, high slope regulation worldwide problem. '7, kraal Jiang Hong rock lake remediation construction headquarters, deputy commander YiRongQi reporters that' after 2 years of governance, high slope treatment project has completed two-thirds, first unit will be the end of next generation lake hydropower station. '

on August 3, 2014, ludian county of yunnan province a magnitude 6. 5 earthquakes, 617 people were killed and tens of thousands of houses or weight loss, 22. Emergency relocated 970000 people. In the bullpen Jiang Hong rock, nearly 10 million square TaFangTi down form the lake, the catchment area of 12087 square kilometers, the actual big, the threat of flood control risk is high, on both sides of the downstream LuDian, home opportunely, zhaoyang three counties ( Area) The town of 10, 30000 more than person, 3. 30000 mu of arable land. Damming body on the right bank slope collapse formed up to more than 600 meters, the slope is steep, fracture development, is still in continuous collapse and caving, seriously endanger the lower security.

in view of the lake lake renovation project governance, kraal Jiang Hong rock lake remediation construction headquarters in maintaining the status quo, overall demolition and pesticides hennessy three scenarios, choose to transform it into a large water conservancy project, has the traditionalists drink, irrigation, power generation, such as tourism, ring library economic benefits. YiRongQi said, 'quake lake formed after the capacity of 1. 700 million square, is a natural reservoir, conventional such DAMS need at least 3 - Four years to build, because of the earthquake, dozens of seconds out. '

sinohydro foundation board co. , LTD. , red rock projects department deputy chief engineer Luo Qingsong introduction, to let the lake play to the function of the reservoir, in dam body side to reinforce a cut-off, prevent the water leakage. But weir body complicated geological conditions, deposit in the collapse of the fall, the large boulder content 60% - 70%, and the deposit is still uncertain, under the condition of the vertical building 1. 2 meters thick, more than 130 meters wide diaphragm wall, are the first in the domestic and world. In addition, the high slope of right bank collapse damming body formation, as high as 600 meters, the slope is steep, crack development, poor stability, control difficulty is world class.

YiRongQi said that the renovation to divided into two parts: the first phase of the lake and victims of the flood control engineering and within the lake dam settlement, including - — Building on the right bank spillway tunnel, damming full high slope governance, damming body anti-seepage reinforcement and other projects; The second phase is on the basis of ensuring the safety of the lake, in lake water downstream areas, such as irrigation and water power engineering. 'In addition to the harm and confrontation, to ensure that the first units by the end of 2017. '

at present, the lake spillway tunnel has all, high slope treatment has been completed two-thirds, diaphragm wall will be completed on October 31, 2017, other host equipment manufacturing, irrigation, power generation water hole, and other projects are also stepping up construction, has completed investment 8. 2. 5 billion yuan. Is expected to the end of December 2017, hydropower station will be the first generating units and has a permanent flood discharge conditions.

red rock lake renovation project, after the completion of the reservoir normal level of up to 1200 meters, the dead water level 1180 meters, has a seasonal adjustment performance, with a total installed capacity of 201 megawatts (mw). At the same time, the project will also realize the irrigation area of 6. 6 30000 mu, water population. 910000 people of good social benefits.
