Aqueduct, that is, in canals, valleys, depressions and highways, overhead water tanks are set up to transport water. Air duct is also called water bridge. The seismic grade of Shahe aqueduct is Grade 8, and its design service life is 100 years. Ten engineering records have been created, with the comprehensive scale of the project ranking first in the world and the length of modern aqueduct ranking first in the world. The century project of South-to-North Water Diversion broke records by Shahe aqueduct, which benefited hundreds of millions of people. Aqueduct is an elevated aqueduct, which is used to transport channel water flowing through rivers, valleys, depressions and roads. The section of Shahe aqueduct consists of beam aqueduct, box foundation aqueduct and floor aqueduct.
This is a veritable century-old project. In order to ensure the safety of the project, nearly ten thousand monitoring points have been set up inside and outside the aqueduct. The settlement of aqueduct is regularly detected, and there is no abnormality so far. Aqueduct is actually a viaduct for water. Because the Middle Route of South-to-North Water Transfer Project flows through Lushan County, the terrain drops sharply and is blocked by local rivers such as Shahe, Da Lang and Jiangxiang. It is necessary to build aqueducts to realize the South-to-North Water Transfer Project. Shahe aqueduct is a large-scale and technically complex control project in the middle route of South-to-North Water Transfer Project.
Shahe aqueduct project is a part of the first phase of the Middle Route of South-to-North Water Transfer Project, which undertakes the task of supplying water and water to the north of Shahe. Ensuring the high-quality completion of such a huge and complex project is undoubtedly a major test for builders. During the pouring process of large U-shaped aqueduct, many influences such as winter construction, flood season and outer membrane deformation were overcome, and a series of technical problems were solved. After the suspension aqueduct is completed, the height of the bridge erecting machine will reach 35 meters, which is equivalent to the height of a building with 12 floors. The construction difficulty and requirements are relatively high. In order to prevent possible leakage, the Shahe aqueduct body is also provided with a rubber water stop. Avoid construction joints. Shahe aqueduct has no leakage so far.
