This newly-built highway connects Huashixia Xiangride to expressway in the south, Chaka to Golmud expressway in the north, Golmud and Delingha, two major cities in Qaidam Basin, and expressway network in the east of Qinghai, making Gobi and Hanhai economy take off and enter? Fast lane? .
The reconstruction and expansion project of Dexiang expressway started in August 20 13, which is a part of expressway, the national highway from Delingha to Marcand (G06 15). The total length of the route is 176486 km, and the whole line is built according to expressway standards. The designed driving speed is 100 km/h, with a total investment of 3.434 billion yuan. Up to now, the investment has been 901100,000 yuan, accounting for 26% of the total investment, 5.24 million cubic meters of subgrade excavation, 5.78 million cubic meters of subgrade filling, 703 bridge piles, 99 culvert foundations 136 roads, 99 walls, 265,438 prefabricated cover plates and 398 prefabricated beams and slabs, accounting for 6,543,398 roads of the total engineering quantity respectively. The project is scheduled to be completed before the end of August 2065438+2006, and has reached the completion acceptance standard.
The geology along Dexiang Expressway is complex, and the whole line is dominated by desert, Gobi, saline-alkali swamp and aquatic plants. In addition, objective factors such as poor access roads, lack of water resources, no power supply, and no coverage of wireless signals such as mobile phones along the line make the construction extremely difficult. Since the start of the project, all participating units have vigorously promoted it? Standardization of management behavior, site construction, construction technology, process control and construction results? In the construction concept, a number of new technologies and equipment, such as numerical control equipment for steel bars, intelligent tensioning of beams and slabs, spraying and curing of prefabricated members, were adopted, which improved the construction quality. At the same time, desert plants should be transplanted and covered in qualified borrow sites, and desert plants such as Kobayashi and Japanese willow should be transplanted 19300 square meters to minimize the impact of highway construction on the ecological environment.
The completion of expressway will improve Qinghai expressway Network? 34 10 net? On this basis, it is organically combined with Beijing-Tibet Expressway G6 line, National Highway 2 14 line, Qinghai-Tibet Railway and Qingxin Railway to form a comprehensive transportation network, which is of far-reaching significance for perfecting expressway network in Qinghai Province, improving production and living conditions and resource development conditions along the line, promoting regional economic development along the line, and promoting herders along the project to get rid of poverty and become rich as soon as possible.
