Accelerate the construction of new progress in the construction of large -scale water conservancy projects 丨 Zhejiang Qiantang River Basin Basin Basin Polying Reservoir Construction Power Construction

On July 5th, the Digitive Cave of Zhejiang Kaihua Reservoir Project successfully opened up, laying a solid foundation for the subsequent dam -off flow, marking the entry stage of the main project of the reservoir.

Kaihua Reservoir Project is 150 major water conservancy projects promoted by the country. It is the backbone storage project of the Qiantang River Basin recommended by the Qiantang River Basin Comprehensive Plan. The total investment of the project was 4.554 billion yuan, and the total reservoir was 184 million cubic meters. After the reservoir is completed, a solid flood control security barrier will be built for the Qiantang River, promoting the enhancement and structural optimization of the Baili Jinxi Gallery, and promoting the high -quality leap -up development of openization.

As a controlling project for the starting flow of the opening of the opening of the Kaihua Reservoir, the total length of the diversion hole is 494.42 meters. The tunnel adopts the section of the city door hole, and the net size of the section is 8 meters × 8 meters. During the construction of the project, it overcomes the unfavorable factors such as the diversion cavity, the poor working space, and the long cycle time, and take measures such as shortfall, weak blasting, and strong support. Essence In the end, the two working surfaces of the diversion hole in the import section and the exit section were successfully achieved.

Since the construction of the project on March 23 this year, the parties to the project have adopted measures to "optimize the blasting plan, keep an eye on key links, and follow the follow -up follow -up" measures to overcome the continuous rainfall during the rainstorm and the shortage of material supply during the prevention and control of the epidemic. Multiple measures to promote the construction of the project. In the next step, it will accelerate the construction of projects such as lining, dug slope excavation support, and water transmission lines to ensure that the opening of the opening of the opening of the opening and effective results.
