Four cable-stayed bridge, Tian 'e County, Hechi City, Guangxi


Tian 'e County four bridge is 611.024m in length, of which the bridge length is 459m. The bridge type adopts 4x20m continuous beam + (70+192+110) m high and low tower three-span central double lock plane cable-stayed bridge. Because of the special-shaped cable-stayed tower and large span, the construction technology requirements are high, it will become a landmark project in Hechi and even Guangxi after completion. The project started construction on August 15, 2019 and is expected to open to traffic in May 2022.


Cross Yudun Port Bridge, Ledu West Road, Shanghai


Shanghai Ledu West Road Cross Yudun Port Bridge, with a total length of 1085.4m, adopts single suspender system along the bridge with 21 pairs of suspender. At present, the construction workers are paving the bridge deck, and 90% of the construction progress has been completed.

Liuzhou Shuangyong Bridge


Liuzhou Shuangyong Bridge, with a total length of 1938.091m and a main bridge of 510m, is a single-main cable slant suspender-ground anchor suspension bridge, which breaks through the construction technical problems of large-span single-main cable single-plane wide-width suspension bridge. It is the first single-main cable suspension bridge in China and has won the Luban Award, the first prize of Sichuan Engineering Survey and Design "Four Excellence" and the Zhan Tianyou Award for civil Engineering.


The Bataishan Glass Bridge in Sichuan Province


The main span of Bataishan Glass Bridge in Sichuan province is 198m, suspended between the angular rock and the transfer platform at 1980m above sea level. The relative height of the bridge deck from the bottom of the valley is about 186m. The relative height of the bridge is the first in southwest China, the third in China, and the first in China.


Nanheng River Approach Bridge


Nanheng River Approach Bridge is 288m in length. The main bridge adopts single derrick system along the bridge, and there are 10 pairs of derrick in the whole bridge. The suspender adopts steel wire finished suspender, tensile strength FPK =1860MPa, but also uses PES7 (C) -109, beam end anchoring. The shape of the main bridge is novel and beautiful, resembling a "butterfly" with open wings.

Guandu Bridge


The total length of Guandu Bridge is 330m, the main bridge is semi-floating system, and the vertical height of the tower is 70m, which is in the shape of ellipse arch. It is the largest span single tower and double cable plane cable-stayed bridge in Shaoxing District at present. The steel box girder of the main span is connected to the top of the main tower by 16 pairs of cable stays. The bridge is unique in shape, ingenious in conception and elegant in shape.


Shanghai Jiangyang North Road Bridge Overhaul Project


The North Jiangyang Road Bridge in Shanghai is an important passage to communicate with the north and south sides of the Strait. The overhaul project adopted the "equivalent replacement technology of temporary derrick system". The segmental structure was adopted to ensure that the old derrick was replaced, while the stress state of the original structure remained unchanged and the carrying capacity of the structure did not decrease, so the construction of the derrick was completed.
