Chongqing, April 1 (Hu Hong) 31, after 20 hours of continuous construction, the second bridge of Tuanjie Reservoir on Xiangfu Avenue, a digital economic industrial park project of Tuanjie Lake, which was constructed by the Eighth Bureau of China Construction, completed the first concrete pouring of block 0 of the superstructure, marking the formal opening of the suspension pouring construction of the superstructure of the second bridge of Tuanjie Reservoir. It is an important step to connect Jiangjin and Shuangfu New Area. The overall construction volume
of Tuanjiehu Digital Economy Industrial Park project is large and comprehensive, with a total of seven municipal roads, of which Xiangfu Avenue is the main road of the city, with a super-large bridge, the second bridge of Tuanjie Reservoir is 356 meters long, the span of the bridge is 90 m + 160 m + 90 m, and the width of the bridge deck is 39 meters. Its structural form is prestressed concrete variable cross-section continuous box girder, with a main span of 160 m, ranking the top ten in the domestic large-span continuous girder bridges.
Among them, the No.0 segment of the main girder of the Second Tuanjie Reservoir Bridge is 11 m long, 19 m wide, 9.8 m high, and the total weight of the segment reaches 2000 tons. The support system adopts the domestic advanced SPS strong support system, which has the characteristics of large bearing capacity, high strength and good stability, and is installed in a modular way. The combination of width and height direction can be adjusted as required, which is convenient and efficient, low-carbon, environmentally friendly and zero-loss, and the maximum single-limb support load reaches 450kN.

In the face of these difficulties, the construction team of the Eighth Bureau of China Construction successfully realized the construction of No.0 block concrete of large-span continuous beam, which is rare in China, through careful planning, scheme comparison and selection, scheme demonstration in the early stage, and rational allocation, technical research, scientific and technological innovation and multi-support.
It is reported that the project of Tuanjiehu Big Digital Economic Industrial Park is one of the first pilot projects of EOD (Eco-environment Oriented Development Model) in China, which is jointly constructed by CISdi Group and the Eighth Bureau of China Construction, and will make full use of green intelligent construction technology, digital ecological simulation technology and green ecological technology in the construction. To build a green, low-carbon and sustainable future ecological park, the project will become an important gathering area for the development of Jiangjin Big Data Intelligent Industry, helping the manufacturing industry to transform, improve quality and develop rapidly.
