Tianshan.com - Xinjiang Daily (reported by Kang Haoyan) The reporter learned from Xinjiang Gezhouba Dashixia Water Control Project Development Co., Ltd. that as of the end of May, the Dashixia Water Control Project, a major national water conservation and water supply project, had completed an accumulated investment of 447 million yuan this year, accounting for 37.6% of the annual investment plan of 1.2 billion yuan. The accumulated investment completed in the project commencement is 6.475 billion yuan, accounting for 72% of the total project investment of 8.997 billion yuan.
At the dam construction site of Dashixia Water Control Project, the reporter saw that a truck load of concrete was poured into the second phase panel warehouse in order. On the big screen of the smart construction site monitoring center a few kilometers away from the mountain, real-time data such as concrete batching, internal temperature, and pouring progress were dynamically displayed, and the construction progress and details were clear at a glance.
"The smart cloud platform system meets the requirements of engineering construction management business automation and process, and realizes real-time monitoring of key construction processes." Zhou Junfang, chief engineer of Xinjiang Gezhouba Dashixia Water Control Project Development Co., Ltd., introduced that the smart system uses blockchain technology combined with Internet of Things technology, and refined management ensures smooth connection of processes in all links, The quality control level of the whole process is improved. The pilot application of electronic signature under implementation has also greatly improved the efficiency of project management. At present, the construction of Dashixia Water Control Project has been transferred to the second phase of face slab concrete pouring, which is one month ahead of the planned construction period.
Moreover, at the joint water intake on the left bank of the upstream of the dam, the towering "tower crane" borrows from the "building crane" technology of high-rise buildings, which is the first time in China's water conservancy and hydropower projects to carry out hydraulic jacking modular design and application of integral formwork for the water intake tower. This set of innovative "large tonnage, long stroke hydraulic intelligent construction machine system" can lift 1518.8 square meters of formwork in a single time within 10 minutes, which is 4-5 days shorter than traditional hoisting and installation operations. According to statistics, the system has saved about 160 days of construction period and about 3.97 million yuan of direct costs since its application.
Dashixia Water Control Project is one of the 172 major water conservancy projects for water-saving and water supply determined by the State Council. It is the world's highest concrete faced gravel dam that has been built or is under construction. The maximum dam height is 247 meters, and the dam height that has been built is 202 meters.
He Wei, Director of the Construction Administration Bureau of Dashixia Water Control Project in the Tarim River Basin, Xinjiang, introduced that up to now, the Dashixia Project has completed 11095 unit projects in total, with a qualification rate of 100%, including 10607 excellent units, with an excellent rate of 95.6%. Since the start of construction, the project has been safe in production for 2360 days without accidents.
