China Gansu News, November 25 (Reporter Song Fangke) 11 On March 23, the acceptance meeting of the Xiahe toll station to Sangke section of the Wangertang-Xiahe (Sangke) Expressway on the S38 line was held. After full discussion by the handover acceptance team, it was unanimously agreed that the quality of the Wangxia Expressway on the S38 line was qualified and qualified for opening to traffic, and the handover was agreed. Previously, the section from Wangertang to Xiahe toll station was opened for trial operation in December 2021. This time, the section from Xiahe toll station to Sangke successfully passed the handover inspection, marking the successful completion of the construction task of the entire line of Wangxia Expressway.
As a provincial tourism expressway, Wangxia Expressway is the first expressway in Xiahe County and one of the connection lines planned by the provincial road network in Gansu Province. It was opened on August 2018 The start of construction is located in Wangertang Town, Xiahe County, which is connected to the Wangertang Junction Exit of G1816 Linhe Expressway, and the end point is located in Sangke Town, Xiahe County. The total investment of the project is 6.49 billion yuan, and the total length of the route is 41.595 kilometers . The whole line adopts the standard construction of two-way four-lane expressway, with a total of 37 bridges and 9 tunnels, and the bridge-tunnel ratio is 63.2%.
After the project is opened to traffic, it will further improve tourists’ access to Labrang Monastery, Sangke Grassland and other scenic spots The convenience of the scenic spot, and at the same time accelerate the construction of a “ring, network, and system” global tourism transportation network in Gannan.
During the project construction process, the Wang Xia project actively practiced the development concept of “innovation, coordination, green, openness, and sharing”, carried forward the spirit of craftsmen, insisted on technological innovation, and high-quality construction Quality Engineering.
According to the actual situation of large temperature difference and short effective construction period in the alpine and high altitude areas, the prefabrication of the box girder adopts a fully enclosed factory construction, and the steel bars are welded by robots, which effectively solves the problem in the alpine areas. The quality of concrete is common, and the production efficiency is improved.
In terms of ecological protection, in order to actively respond to the national strategy of ecological protection and high-quality development in the Yellow River Basin, the project adopted ecological route selection, intensive land use, emission reduction and carbon reduction, and reduced land filling Height and other measures to do a good job in the top-level design of project construction and ecological protection. The introduction of a new type of prefabricated zinc-aluminum alloy wire gabion protection maximizes the protection of the original ecology of the grassland and harmonizes the road with the natural landscape. The subgrade side slope of the grassland road section adopts a 1:2 (gentle slope) slope to the bottom, so that the road construction conforms to and integrates with nature.
