The hoisting of the first bolted section of the Shunde Bridge was successfully completed

At 7:30 on April 9, 2023, following the issuance of the hoisting command from the on-site control room, the smart tower crane slowly hoisted the left section of the T18 section of the high tower of the Shunde Bridge with a weight of about 144 tons. After climbing and translating, it smoothly descends to the predetermined position and performs positioning. So far, the on-site construction of the bolted section of the Shunde Bridge has officially started.

The T16 section of the high tower is a steel-concrete joint transition section, and the ring welding between the T16 section and the T17 section is the difficulty and focus of the welding work of the whole tower. Aiming at the actual conditions of T17 section anchor pipe joint welding deformation accuracy and high quality control requirements, intensive reinforcement in the warehouse and limited working space, as well as the adverse effects of heavy rain, wind and dense fog for days, the project department compiled a special plan for high tower T17 welding In addition, special technical safety disclosure, careful organization and safe construction have been carried out, laying a solid foundation for the hoisting of the first bolted section and the subsequent construction of the bolted section.

CHINA RAILWAY BAOJI BRIDGE GROUP CO.,LTD. The two H-shaped steel towers of the Shunde Bridge have a total weight of more than 18,000 tons and a total of 300,000 sets of high bolts. It is the first time in China to adopt the variable-section steel-concrete combination of lower tower columns (welded) structure, the upper tower column and other cross-section machined pure steel (bolted) bridge tower structure, with a main span of 626 meters, is the world's largest span steel-concrete composite cable-tower cable-stayed bridge.

The 246-ton large section of the Pingshan Viaduct was successfully hoisted

On April 7, 2023, the large section of the 14D1 equal-height variable-width steel box girder of the 14th section of the Pingshan Viaduct Shenzhen direction, the reconstruction and expansion project of Shenshan West Expressway, was successfully hoisted. The large section is 10.5 meters long, 42 meters wide, and has a total weight of about 246 tons. The successful hoisting has laid a solid foundation for the scheduled closure of the Shenzhen side and the Huizhou side.

In April, the on-site construction of the Pingshan Viaduct entered a critical stage. In order to ensure the progress of the construction, all the staff of the project department went all out to make full use of the short-term favorable weather to seize the progress of the construction period. Up to now, 61.9% of the total project volume has been installed and erected for the Pingshan Viaduct of the Shenshan West Project. All the work has been well received by the participating units and the owners!

It is reported that the Shenshan West Expressway Reconstruction and Expansion Project has a total length of 146 kilometers. It is currently the expressway reconstruction and expansion project with the largest investment scale and the longest mileage in Guangdong Province. After completion, it will effectively promote the economic development and development of the Shenshan Special Cooperation Zone and Eastern Guangdong. Industrial upgrading helps Shenzhen to build a pioneering demonstration zone of socialism with Chinese characteristics and the formation of a new regional development pattern of "one core, one belt and one zone" in the whole province. CHINA RAILWAY BAOJI BRIDGE GROUP CO.,LTD.G01 has undertaken the construction of 4 steel box girder bridges, namely Pingshan Viaduct, Songzikeng Bridge, Songzikeng Flyover, and Jikeng Road Flyover, with a total engineering volume of about 46,000 tons.Editor/Ma Xue
