The tunnels of the Hanbanan Railway Nanchong are all connected!There are only 2 seats left in Pakistan

At 9 am on July 26, the construction management of the Sichuan Road and Bridge Group Machinery Company, the Sichuan Road and Bridge Group, which was built by the Shu Road Investment Group, and the Gaopanqiao Tunnel undertaken by the Ninth Bureau of China Railway at the same time. It marks that all the tunnels in Nanchong in the Hanba South Railway are all connected. It has opened up the blocking point of the beam channels in Nanchong, created good conditions for the subsequent beams and rail paving operations, and laid a solid foundation for the completion of the entire line.

The osmanthus tunnel is connected to Shunqing District and Peng'an County, which is 3222 meters in a dual -line tunnel with a maximum of about 150 meters in length. Model cave door. During the construction process, there are bad geological conditions such as faults, neutral water, and local enrichment shallow sky gas. The construction environment and conditions are complicated, and the organization is difficult.

Gaobanqiao Tunnel is located in Lingtai Township, Shunqing District, Nanchong City. It is 138 meters in length and is a double -line tunnel. The maximum burial depth is about 15 meters. It is a shallow buried tunnel. The exit end is a single -pressure cave door. The tunnel travels in the hills, and the terrain is large, and it is worn through gas pipelines, houses and other buildings. The construction is difficult and the safety risk is high.

The construction of the Hangbanan Railway Station of the Osmanthus Tunnel and the Gaobanqiao Tunnel 1 was completed in front of the Hanbanan Railway Station in November 2020 to complete the public bidding. It entered the market 11 months later than other bid sections. The railway company leads the project department to carefully organize, scientifically constructs, keep an eye on key processes, and strictly follow -up points in accordance with high safety quality and high standards. Promote the application of intelligent devices. Adopt measures such as "short -scale ruler, weak blasting, strong support", and equipped with multi -functional intelligent arch installation of trolley, self -propelled hydraulic high -pressure high -pressure stretch trestle, intelligent pouring two -line car cars, etc., to ensure safety and quality Under the premise, the construction efficiency is greatly improved. Actively cope with the complex construction environment and conditions. Equipped with a series of facilities and equipment such as facial recognition access control systems, handheld methane and other toxic and harmful gas detection equipment, high -definition monitoring video systems and other facilities, conduct comprehensive monitoring and control of the construction in the cave to effectively prevent and resolve various risks. Ensure the safety and normal production of construction personnel. Due to the continuous release of the heat of various machinery and concrete, the temperature in the cave is rising, and the project department actively adopts measures such as fog artillery sprinkle water to assist dust and cooling, and distribution of heatstroke prevention drugs to ensure the safe and normal production of tunnel construction personnel.

There are 56 tunnels across the Hanbanan Railway, with a mileage of 59508.441 meters. Among them, there are 40 tunnels in Nanchong, with a mileage of 27441.39 meters, which have been connected so far; a total of 16 tunnels in Pakistan and China have a total mileage of 32067.051 meters. Connect at the end of October.

The Hanbanan Railway Nanchong to the middle of Pakistan is located in the northeast of Sichuan Province. It is the basic project of regional economic collaboration. After completion, it will become an important channel for Sichuan in the northeast of Sichuan. The layout of the railway network is of great significance to help the traffic and economic development of Qinba Mountain and promote the rapid development of regional economic and social.
