New breakthroughs in the construction of the largest single "inverted siphon" water divers

Guanyin Mountain inverted siphon's longest slope segment pressure steel pipe installation

Yunnan Net News (Reporter Hu Xiaorong Correspondent Yang Pinghai Ma Bihui) On June 11, the installation of the longest slope steel pipe of the longest slope section of the Guanyin Mountain in the Central Yunnan Draving Project in Central Railway Seventh Bureau was completed, marking the largest monomer under construction in the country New breakthroughs in the construction of "inverted rainbow" water diversion project.

The slope section of the slope section of the slope is located at the import connection of the Tunnel of Caijia Village. The slope section is 224.6 meters in length, the slope is 13.9 degrees, the single -section steel pipe with different thickness steel pipes is more than 20 tons. Due to the limitation of the terrain of this section, pipeline transportation and installation are difficult. In order to ensure the smooth installation of the slope segment pressure steel pipe, the project department has organized the industry's system research on the basis of the on -site exploration before installation, compiled special construction plans, emergency plans, and continuously optimized technical safety guarantee measures to provide reliable stress steel pipe installation of reliable steel pipe installation Technical Support.

During the construction process, the project department actively responded to the call of "speed up and creating good achievements, welcoming the 20th National Congress of the Communist Party of China" labor competition call, mobilized professional construction teams, scientifically allocated production elements, strengthened training for underworld, and production of pressure steel pipes production. , Transportation, installation, implementation of dynamic management and strict monitoring, comprehensively controlling every process at the site, so as to achieve the first setting and model lead, ensuring safety, quality, and progress to meet the contractual requirements of the contract. Feng Feihong, the leader of the "Feihong" employee technical innovation studio of China Railway Seven Bureau, introduced that the project's innovation uses intelligent chemical equipment to improve construction efficacy and effectively reduce construction costs.

The Guanyin Mountain in the Central Yunnan Draving Engineering Guanyin Mountain has a total length of 9.78 kilometers. Mi, as of now, the Guanyin Mountain inverted siphon has completed a total of 3,420 meters of stress steel pipes.

The water diversion project in Central Yunnan is the iconic project in the 172 water conservancy projects determined by the State Council. The month is the largest investment scale and the most difficult construction water conservancy project in Yunnan Province's history and current water transfer projects. After the completion of the project, the average annual water diversion volume reached 3.403 billion cubic meters, which will effectively alleviate the dilemma of water shortage in central Yunnan.
