01Hambanan railwayProgress in construction
On 18 march, at 9. 30 a. M., a critical moment was observed at the hambanan railway. A section of 315 metres long and 172 tons of pre-fabricated sorghum, which is precisely mountedEunyang river bridgeThis marked the official entry of the bridge into a new phase of silo assembly. The nyang river bridge is a controlled work of the hambanan railway and its installation is important for the passage of the full-line track. According to secretary liu zhigang, secretary of the hanbarn inter-city railway limited, the nyang river bridge is expected to be fully installed in november this year, thus laying a solid foundation for the full-wire pavement and follow-up of the hanban railway。
The hanbanan railway is filled southward to the centre of ba, located in the north-east of sichuan province, with a direct line of 148 km long and designed at 250 km per hour. The completion of a full-line railway is expected to take place in 2024, when it will further boost transport and economic development in the region。
Nyang river bridge
The nyang river bridge on the hambanan railway, located in nyang district, ba ' cheng, is a great bridge. It has a total length of 1416. 465 metres and a maximum of 89. 44 metres and a maximum of 136 metres. The upper structure of the bridge ably integrates four processes, namely, condensed arches, condensed beams, continuous fresh structures and sections, making the structure complex and diverse. This construction organization is extremely difficult, but it is also one of the controlled works of the hambanan railway, which demonstrates the remarkable success of mankind in the construction of transport。
Construction techniques and processes
The head-columns are co-mingled with a silo set up for site disclosure. The construction of the nyang river bridge as a controlled work of the hambanan railway is extremely difficult to organize. In recent days, journalists have visited the site where the first section of the bridge has been installed in a silo. It is understood that the bridge has a total of 14 boreholes assembled in a condensed box, the head of which was placed. The beam is 64 metres long, the beam is 12. 2 metres wide and is 5. 4 metres high and weighs a total of 2332. 8 tons, which is made up of 17 beams that are convoluted through 16 seams。
On-site, li yugou, the project manager of the hanbanan railways in the 2nd central steel bureau, was advised that each pre-fabricated sorghum link would be constructed using structures similar to the “dip” to ensure the integrity of the link. At the same time, the safety of the bridge has been further enhanced by the passage of the steel winch through the holes pre-positioned in the beam. In addition, the sutures between beams were adhesived through glue and ensured the accuracy of the work。
It is worth mentioning that the nyang river bridge of the hambanan railway is the first bridge in sichuan province to introduce a piece-laying process on high-speed railways. Its high level and breadth have created one of the highest bridges of its kind in the country, amply demonstrating the remarkable achievements of humankind in the area of transport construction. At present, the project department is well organized and scientificly undertaking construction, and it is expected that the consolidation of the sections will be fully completed by the end of october, by which time the bridge surface operations will be synchronized and track-laying operations will be carried out to provide solid guarantees for mid-to-sungdu rapid transport。
Economic and social impact of railway 02
1. The meaning of the line and the way forward
The hanbanan railway south-south to the centre of baal, the first high-speed railway in sichuan province to be fully funded and led by the local authorities, has far-reaching implications. This route, which crosses the old qinba region and the mountains of qinba, not only enhances the geographical advantage of the areas along the border, but also lays a solid foundation for integration into the economic belts of the national silk road and the yangtze region。
At the same time, it has implemented the plan for the revitalization of the region of the trunchuan revolution, which has played an important role in promoting the rapid development of the north-east economic zone of the province, improving the inter-city railway network in the chengsu region, improving the coverage of the railway network in the centre-west and developing red eco-tourism。
2. Construction and mobility expectations
At present, 80 per cent of the pre-station work on the hanbanan railway has been completed and is expected to be fully completed by the end of the year, with the commencement of the pavement work next year. Full-line control works, including the eunyang river bridge, the kayin river bridge, the shining tunnel and the east hua mountain tunnel, will also be completed by november. In the second half of the year, the re-orbiting work will commence. It is expected that the hanbanan railway will travel in the first half of 2024, at which point the north-east of kawakawa will be officially integrated into china's high iron network, with chengdu travelling for up to 75 minutes, and chongqing travelling to bain china for up to 90 minutes。
