The world's largest!"Tianhe Interchange" opens

Recently, the world's largest span steel groove, the Jiangji Huaihuai project, the Steel Grain Steel structure of the Luohe project for the first time navigable.

Luohe's general man was hung in the air, forming "Tianhe Interchange" with the channels of Yinjiang Jihuai.

Gujiang Jihuai Project is the "No. 1 Project" in infrastructure construction in Anhui Province. The total length of the total drying groove of the Huaihuai River in the Yinjiang Jihuai River is 350 meters, which are divided into two left and right pieces. Among them, the total length of the steel sink is 246 meters, and the main span is 110 meters. It is currently the world's largest span of water -passing steel structure. The construction of the general canal built in December 2018 was started. On October 28, 2019, the installation of the steel beams of the hear tank officially opened. On October 26, 2020, the steel hear grooves went left to the left. On November 5, 2020, the steel heterocratic grooves were smooth and smooth. On May 1, 2021, the steel heterocratic water was successful.

Luohe's general canal steel hear flow is 150 cubic meters per second, and the water depth is 4 meters. Considering that the water level of the Luohe in different seasons is very large, the arched steel heterogeneous can effectively solve the problem of variable water load. After navigation, a single hear tank can carry 20,000 tons of water and can pass 100 tons of ships.

The main span of the general drying tank of the Huaihuai River in the Yinjiang Jihuai River is 3.8 meters longer than the world -famous Magdorburg Water Bridge in Germany.

Before the bridge was built, the ship had to go from the Yi Bei River into another canal, and through two slurations, it was often time -consuming and labor -intensive. After the water bridge on both sides is completed, the ship between the canal does not need to bypass. The range was shortened by 12 kilometers, the transportation efficiency was greatly improved, and the transportation costs decreased.

The leading channel of the Huaihuanghe River in Yinjiang is not only the world's largest span, the water -intensive steel structure heterogeneous, but also the first domestic truss -type beam -arch combination system. The structure consists of a full -welded overall node truss -like arched and the inner sink. The structural production process is complicated, the construction is difficult, and there are many innovations. Among them, in order to ensure the safety of drinking water, considering the impact of large variable water loads on the structure in the seasons, the designers invented the stainless steel composite twists and turns and applied it to the bridge, making the structure rigid and soft.
