Bridge event: The first Sanco Saddle, the longest cross -sea bridge in Guangxi, complete the hanging

The longest -across sea bridge in Guangxi completes the hanging saddle!

On September 26, the Longmen Bridge Project made breakthrough progress: the west anchor scattered saddle body and the base achieve accurate docking. The Longmen Bridge completed the first Sando saddle installation operation, and officially opened the upper structure construction.

The Longmen Bridge is the longest cross -sea bridge under construction in Guangxi. It is the first kilometer -class cross -sea suspension bridge in Guangxi. The project route is 7.637 kilometers in length, of which the total length of the bridge is 6597 meters.

As an important structure of the suspension bridge, the main role of San Corinee is to change the direction of the main cable, scatter the main cable into a cable stock and anchor them separately on the anchor. A total of four scattered saddles of the Longmen Bridge. This time, the saded saddle body was lifted on the left. The weight of the lifting is 80.2 tons, and the height of the lifting is 50m. The lifting operation time, high risk, restrictions on operational space, the angle of the saddle body and the control of installation accuracy are difficult.

The project department of the Longmen Bridge Zhongjiao Construction Project uses the BIM 3D technology to accurately simulates the on -site lifting data. Choose a 400 -ton large crawler hanging equipment for lifting operations. Under the guidance of professional and technical personnel, the saddle body was lifted smoothly, successfully connected with the base, and successfully completed the installation of the first saddle body.

At present, the Longmen Bridge project has entered the upper structure construction. It is expected that the anchor scattered saddle on both sides of the east and west sides of the east and west sides of the west is expected to be lifted, and the main saddle installation is simultaneously completed.

The full bridge of Tieshan Port Cross -sea Bridge runs through!

On September 26th, the key control project of the renovation and expansion project of Qinzhou to Beihai section from the Lanzhou to Haikou Expressway -Tieshan Port Cross -Sea Bridge left the last 30 -meter box beam to complete the setting up. , Laid a solid foundation for the full opening of the Qinbei reform and expansion project at the end of the year.

The reconstruction and expansion plan of the Tieshan Port Cross -Hait Bridge is to build a new bridge on the right side of the existing old bridge. When the new bridge is completed, the vehicle is split, and the upper part of the old bridge and the beam of the cover beams are integrated into one. The bridge of the bridge of the bridge is 4279 meters in length, upgraded from 4 lanes to 8 lanes, and the design speed is 120 km/h.

As the first scientific and technological demonstration project in Guangxi, the project department actively launched the "Four Micro · Four New" activities to innovate the series of methods of demolition and reconstruction of Tieshan Port Bridge; always adhere to environmental protection construction Concentrated processing stations of mud, introducing "black whirlwinds" for mud recycling and use to achieve environmental protection and efficient construction, adopt advanced and reasonable construction equipment and processes, strictly arrange operating procedures in accordance with the operating procedures, greatly shorten the construction cycle, and minimize the project to reduce the project to maximize the project. The impact of construction on the regional mangrove ecosystem.

The smooth penetration of the whole bridge of Tieshan Port Cross -sea Bridge has greatly improved the land traffic capacity of Guangxi Beibu Gulf Economic Zone to the Pearl River Delta. It is a new breakthrough in the construction of the new land and sea channel in the western part, which is conducive to further release the potential of "sea" and build a good economy.

Ganxi Special Bridge Quanqiao Shunhe Heilong

On September 26, as the last side of the concrete was poured, the Ganxi Special Bridge officially co -formally. The project is located in Guiding County, Guizhou Province. It spans the Dumuhe Reservoir in Ganxi Forest Park. It is a key project that connects Guiding County, a small red town -Xinba Town. The bridge is 1220 meters in length, which is the second empty stitching bridge in the world. Its 300 -meter -shattering is the first -type bridge -type world in the world.

During the construction of the bridge, the project construction team was stationed in the deep mountain valleys. More than 1,000 days and nights of the battle, successfully broke through the construction of the mountainous roads, the construction of large -scale piles, the large -volume concrete watering water construction, and the risk of thin walls and high pier risks. In terms of control and control, successfully overcome the difficulty of cross -climbing basket construction technology in the triangle area. The deduction of the device, etc., creatively solves the various technical problems in the construction of this type of bridge. It has applied for nearly 20 patents and has been authorized.

This bridge Heilong marks the new stage of the bridge span of the empty stomach rigid structure in the world. Compared with the steel structure type bridge of the steel structure of the cable bridge and the suspension bridge, the bridge has durability and saving the development of later development in the later stage. The advantages of this this have added a new chapter to the history of the world bridge. (Source: Tencent.com)

Guangdong Hongqimen Bridge Accelerate Construction

On September 26, at the construction site of Hongqimen Bridge, a central (Zhongshan) highway controlling engineering in Nansha District, Nansha District, Guangdong Province, construction site was constructed at the construction site of the Hongqimen Bridge of Hongqimen Bridge.

At present, the East Tower column has entered the construction stage of the Heilong section, and it is immediately capped. After the completion of the South China Central Expressway, it will further strengthen the interconnection between the Guangdong -Hong Kong -Macao Greater Bay Area and help the economic and social development of the Greater Bay Area.
