in Pakistan Su Jike na ( SukiKinari) Hydropower station ( Hereinafter referred to as the 'SK hydropower station') On September 28, successful river closure, the project by the Chinese can build gezhouba group investment, construction, operation and transfer, solar equipment, construction for more than two years, builders successfully conquered many world class problem.

SK hydropower station project is the 'china-pakistan economic corridor' first priority list of key projects, a total installed capacity of 884 megawatts, with a total investment of about 19. $600 million, so far the Chinese enterprise in greenfield investment outside the territory of the people's biggest hydropower project.

126 m dam cut-off is the guarantee of the dam closure of their project. Quality of dam seepage der-chen chang, head of the introduction, the depth of the diaphragm wall is the biggest problem facing the engineering construction, beside the domestic only Tibet cut-off power station played more than 120 meters. 'Because of the uncertainty of the geological conditions, in the process of drilling, drilling to edge, edge to fill some loess mud bentonite mud and ensure cut-off hole collapse. 'Der-chen chang said.

　　642. 61 meters world's deepest pressure shaft construction difficulty is one of the largest and most technical requirements for the key projects. SK hydropower station pressure shaft steel pipe section for the double hole, can be divided into vertical section and horizontal section, the 3 steps that decorate, pressure steel pipe segment elevation difference for 737 as a whole. 94 meters, solar panels, a single shaft segment ( Divided into 3 section) Deeply, 642. 61 meters.

Zhang Hongshan, associate director of the project department technology is introduced, the global hydropower project shaft depth are numbered more than 500 meters, pressure shaft SK hydropower station group will break the family card, Ecuador Anne Sinclair hydropower station 544 meters pressure shaft of the world's deepest record.

'difficulties emerge in endlessly, measures also everywhere, we are in the process of the game, drive the project forward step by step. 'Sea gezhouba company party secretary, chairman xiao-dan Lin said, start from March 30, 2017, the construction unit system, pushing forward the construction of the project as planned 136 days to complete the cable hole excavation construction in advance, implements the tail sand system operation, 12 days in advance 15 days in advance to complete the main plant for rock anchor Mr Rock excavation.

in recent years, deep Pakistan and gezhouba group more successful construction has the important status in the bilateral economic and trade relations of large water conservancy and hydropower, wind power, highway project, signing contract amount more than $10 billion.

among them, the construction of gezhouba group NJ hydropower unit successfully all over, solar portal, to solve the problems of shortage of electric power for 15% of the population to Pakistan; Construction of DASU hydropower station is one of the most difficult, the total installed capacity of the largest Pakistani technology, one of the largest project total investment; Construction of Mohmand hydropower station is the first flagship to Pakistan's new government project; Construction of E35 highway connection between China and Pakistan youyi road, promote china-pakistan economic corridor connectivity.

at the same time, China's solar energy network, gezhouba group also contract to build the new energy Pakistan's first overseas EPC general contracting project - — Jim's joint energy 99 megawatts of wind power projects, solar power grid, the first road project, an investment bank - — The M4 motorway project, china-pakistan economic corridor priority implementation projects - — A large number of KAROT hydropower project benefit the local people's livelihood project. In the process of project construction, the gezhouba group implement local administrator mode, to provide local nearly thousands of jobs. ( the
