On July 27, the construction of the Lijiang -Shangri -La Railway, which was under construction, made significant progress. The entire control engineering Haba Snow Mountain Tunnel was conducted in front of the cave, which proved the geological conditions and effectively released the high ground stress. Essence The Haba Snow Mountain Tunnel is located in Diqing Prefecture, Yunnan Province, with a total length of 9.5 kilometers. The maximum burial depth of the tunnel is 1155 meters. The geological problems such as lithograph and soft rock deformation are extremely prominent.

In order to overcome the construction difficulties, the participating units adopt a advanced and mid -to -mid -to -construction process to release the geographical stress scheme. "The middle guide hole is in the positive hole. Put a hole with a relatively small hole in the positive hole, so that the guide hole releases a part of the stress during the deformation process, and then the positive hole is expanded. Completed. "Wei Peng, head of the Lixiang Railway Project Department of China Railway 16th Bureau.

Since the beginning of this year, Yunnan has vigorously implemented the railway "network speed up" project, highlighting the shortcomings, strong weaknesses, and heavy supporting facilities, scientific, orderly, safe and high -quality promoting the heavy difficult projects such as the Lixiang Railway, Metron high -speed railway, and the Darui Railway breakthrough.

On July 22, after 14 years of hard work, the Dali (Li) Railway (Li) Railway Dali to Baoshan section was officially opened and operated. "Due to the terrain restrictions, the Xiuling Tunnel can only adopt the two -distance digging method of import and export. For 14 years, tens of thousands of workers participated in the construction." Said Qiao Zhiqiang, manager of the Xiuling Tunnel export work zone of the China Railway Eighth Bureau.

On July 26, at the construction site of Mongolia to Mongolia high -speed rail from Mongolia, Honghe Station, Kaiyuannan Station, Pengpu Station, and Zhuyuan Station, the construction and equipment installation and commissioning were completed in full. Operations within the year. Xu Kun, chief engineer of the China Railway City Construction Group Mimon High -speed Railway Station project, introduced that the total construction area of ​​Honghe Station is 44,000 square meters, and the total construction area of ​​the station building is 28,000 square meters. Large -scale comprehensive hub station. According to statistics, as of July, the management of the China Railway Kunming Bureau Group completed the basic construction investment of 3.155 billion yuan, accounting for 55.37%of the annual plan.
