Qingshui River Project

The Qingshui River project starts at the intersection of Jingliu Road and Wutun Road in Qingshui Town, crosses the Qingyi River from north to south, and connects to Wutun Road. The route is 1.864 kilometers long, including a 1.017-kilometer bridge, and is designed as an urban Class I arterial road and first-class highway with eight lanes.

Huishui River Bridge

Huishui River Bridge is located in Jingde County, Xuancheng. The bridge is 232 meters long with a span arrangement of 3.5+30+135+2x30+3.5 meters. The main bridge superstructure adopts a 135-meter steel box girder tied arch.

Qinjiang Extra Large Bridge

Qinjiang Extra Large Bridge is located in Pingji Town, Qinzhou, Guangxi. With a total length of 1,873 meters and a 245-meter main span, it is a key control project of the Qinzhou North Bypass Highway. The main bridge consists of two extradosed cable-stayed bridges.

Tiantian Expressway

For the Changhe Extra Large Bridge on Section 10 of the Tiantian Expressway, the superstructure adopts a 72+133+72-meter prestressed concrete partially cable-stayed bridge. The bridge uses a pylon-girder fixed and pier-girder separated system, vase-shaped solid piers, pile group foundations, and 408 box girders.

Xiejiang River Project

The main bridge of the Xiejiang River project is designed as a single-pylon, double-cable-plane prestressed concrete box girder cable-stayed bridge with a 52+78+160-meter span arrangement. It adopts a three-span continuous fixed system and dense spatial cable layout.

Beijing-Kowloon Railway Project

This bridge on the Dezhou-Shangrao Beijing-Kowloon Railway project has a 100-meter main span, 70-meter side spans, and weighs about 23,500 tons. It innovatively adopts an asymmetric extradosed cable-stayed structure, balancing architectural aesthetics with engineering economy.

Zidong Bridge

Zidong Bridge is located in Nanzhuang Town, Chancheng District, Foshan, serving as an important link to Xiaotang and Luocun in Nanhai District. The 1,034-meter bridge uses a twin-pylon single-cable-plane concrete-filled steel tube spatial truss cable-stayed structure with a 69+140+69-meter span arrangement.

Jining Port Longgong Port Railway

The Jining Port Longgong Port dedicated railway line is located in Rencheng District, Jining, Shandong, with a total length of 9.37 kilometers. Its main works include the 6.346-kilometer Quliuzhuang Extra Large Bridge with 220 spans of prestressed concrete simply supported T-girders and two tied arch spans.

Hongshui River Extra Large Bridge

Hongshui River Extra Large Bridge is a large through-type tied arch bridge in Xingbin District. It is 1,732 meters long with a 285-meter main span and reaches 108.5 meters above the water. The main arch ribs are erected with advanced cable hoisting technology using 131-meter hoisting towers.

Kaixia River Extra Large Bridge

Guizhou Kaixia River Extra Large Bridge is an asymmetric 180+230-meter semi-floating single-pylon composite girder cable-stayed bridge. It crosses the Kaixia River valley and a U-shaped dissolution valley, with a 30-meter-wide composite girder, an A-shaped 117-meter pylon, and 72 epoxy-coated strand stay cables.

Yiyang Bridge

Yiyang Bridge is 655 meters long and 33 meters wide, designed for six lanes in both directions. The 245-meter main bridge is a single-pylon, single-cable-plane cable-stayed bridge with a maximum structural height of 178 meters and a 130-meter main pylon.

Tongji Bridge

Tongji Bridge runs from Changang East Road to Jihua North Road. The route is about 1.54 kilometers long, including an 892-meter bridge with a 33.5-meter deck. Its stay cables are 66 to 214 meters long, with standard cable spacing of 12 meters on the main span and 6 meters on side spans.

Qiyun Bridge

Qiyun Bridge adopts an antisymmetric hybrid-pylon steel box girder cable-stayed structure with a 75+118+75-meter span arrangement. The Fuchun Avenue side span and main span use a one-way longitudinal gradient, while the approach bridge has a 3.5% gradient.

Xin'an River Bridge

Xin'an River Bridge is equipped with 36 stay cables, the longest reaching 200 meters. Its double-cable-plane fan-shaped layout forms a spatial load-bearing system that combines structural performance with a folding-fan visual expression, improving load transfer efficiency and stability.
