Guangxi Tian'e: Chongshan Junling Dragon Flying

The full picture of the Tian'e Hub communicates.

On July 14th, Guangxi, the largest and largest hub of the Pingtang to Tian'e Expressway, which was invested and constructed by Guangxi Transportation Investment Group and built by the China Communications Second Aviation Bureau, and the Tiandi Highway Tian'e Hub has successfully achieved the entire line.

Tian'e Hub's interoperability.

The total length of the bridge within the interoperability of the Tiandi Hub is 4758 meters, covering an area of ​​250,000 square meters, including 728 pile foundations, 171 inheritance, 330 pier pillars, of which 123 are above 40 meters, and high above 80 meters high. There are 6 pier, 185 cover beams, 1317 榀 in prefabricated T beams, and 5 interchanges, of which 4 are not satisfied with the height of the beam. The construction scope of the bridge construction is large, high in the mainland, steep hills, and difficulty in construction technology.

Workers are under construction on the interoperability of Tian'e Hub

The connected Tian'e Hub is located in the northeast of Hongshuihe District, Tian'e County. Within a total of 12 reasons bridges and 1 main bridge, its main bridge, the Tian'e Hub Interchange Bridge, Cross -Sky Emi Hub Interconnected B Ring 1 Bridge and No. 4 Bridge 4, connect the Nahei Nahei 1 Bridge through the B and C ramps, and the end point is connected to Tianba high -speed. Key nodes of highway penetration.

Tian'e Hub's interoperability.

In the construction of large -scale hub -connected bridges, the project vigorously carried out scientific and technological innovation, promoted the application of "four new technologies", improved work efficiency, and actively created quality projects. In the process of prefabrication of T beam, innovatively developed the "prefabricated beam guardrail overall embedded construction construction method" to effectively solve the large welding volume of bridge prefabricated beams, high welding, low efficiency, high work safety risk, high -altitude, high -altitude operation safety risk risk high risk The problem won the silver award of the National Highway Micro Innovation Contest. During the construction of the wet joint of the upper structure of the bridge, innovatively developed the "concrete beam telescopic joints overall pouring section construction method", and solved the traditional bridge telescopic joint construction. Repeatedly bent on the board, prone to fracture of fatigue, and won the bronze award of the National Highway Micro Innovation Competition. At the same time, new equipment and other new equipment such as Guangxi's first high -power excavation, laser ultrasonic paving machine, etc., further ensured the quality of construction, saved labor costs, and achieved significant implementation effects.

The Tian'e hub interoperate.

The Pingtang to Tian'e Expressway is located in Nanyan County and Tian'e County, Hechi City, Guangxi. It starts near Yunyang Pass, Yueli Town, Nanyang County, Qiangui Province. Essence The main line is 59.2 kilometers long, connecting the Nandian Expressway and Tianba Expressway. It is an important part of the "Top 10" Tian Emi to Beihai Expressway. It is of great significance to improve the national highway network and regional highway network, improve regional traffic conditions, and accelerate local economic development. The project № 4 contract section, the main line length is 7.6 kilometers, the main line base length is 3102.5 meters; the main line bridge, 2 tunnels; 1 interchange interchange. The inner bridge tunnel ratio is 59.1%.

Tian'e Hub's 80 -meter -high pier.

As of now, the base of the Pingtian Highway, the bridge pile foundation, the pier pillar, the tunnel excavation, the two -lined, and the housing construction project have been completed; the tunnel project has been completed by 92%; the house construction decoration project is 70%; %, The water stabilization layer is completed by 42%, and the launch section of the lower layer test section of the asphalt has been carried out; the prefabrication of the beam board has completed 97%and the installation is 92%. Top 2022 target. (Gao Dongfeng Sun Longyang Photography Report)
