On July 18th, the Journalist reporter learned from the China Railway Bridge Bureau that on the morning of the 17th, the construction of the main bridge of the main bridge of the main bridge of the Tuzao Bridge of the Chaoshan Ring Road Expressway 3#main construction was completed, marking the completion of the main pile foundation of the bridge. It will fully enter the construction stage of the main pier inheritance, and lay a solid foundation for the completion of the construction tasks this year.

It is reported that the Chaoshan Ring Road Expressway (including Chaoshan Links) Third Phase 3 project Jingzao Bridge Civil Construction 2 Tiber, located in Jieyang City, Guangdong Province. This project is a provincial key project that promotes the traffic of the three cities in Shachaojie. The construction of the road and bridge company and the construction of the China Railway Bridge.

According to Li Gen, the executive deputy chief engineer of the project, the main bridge of Jingzao Bridge is the two -tower double cable surface and semi -floating system steel concrete combination beam. In order to meet the navigation requirements, the bridge crosses the river, the main span 350 meters, 2# The 3#pier is two main pier, with a total of 52 pile foundations. The pile foundation is 2.8 meters of diamond drilling piles in diameter, and the longest pile is 135 meters long. Due to the thick coverage layer of the bridge and bridge, the lower lying stiff granite is located in the Rongjiang Rongjiang Fracture and the Second Railing Belt, and the geological conditions are complicated; The pile foundation construction is one of the key core technologies of the bridge.

The project team strictly implements the requirements for norms

In order to ensure the smooth progress of the pile foundation construction, the China Railway Bridge Bureau gives full play to the technical advantages of the bridge construction of the Bridge National Team, carefully organized, and overcome difficulties. Carefully control each link and treat each pile foundation construction at the "first system" standard. At the same time, the project technology team has continuously strengthened the application of scientific research and innovation, carried out in -depth research on the research technology of super long pile foundation, and further innovated and enhanced the construction technology of super -growing pile foundation under complex geological conditions, providing valuable scientific research for the same type of pile foundation construction technology Innovative results.

It is understood that after the completion of the Beijing -stove Bridge project, it will effectively solve the needs of hundreds of thousands of people on both sides of the Rongjiang River in Chaoshan District, Guangdong. At the same time, the project connects Shantou City and Jieyang, which will further strengthen the traffic context of the "Shachaling Jie" three -city industrial cooperation platform, build a regional development framework and pattern, and in order to promote economic coordination, complementary advantages, cooperation competition, and common development, Give play to a positive role, accelerate the development concept of "Shachariejie Tongcheng", and achieve an important promotion role in the "five -year changes" and "ten -year development" in eastern Guangdong.
