focus on!New progress has been made in the construction of Jianli Expressway

On September 23, with the sound of the "bombardment", the 1145 -meter operating surface of the Sword -Lei Expressway Four Magnolia Liangshan Tunnel Cave, which was built by the China Railway Construction Bridge Engineering Bureau Group, was successfully connected, 10 days earlier than the expected construction period. There are last 30 meters left on the left 1152 meters, and it is expected to penetrate around October 10. At this point, the six operating surfaces of the Tunnel of Jianli Fourth Standard Project have been successfully connected. It marks a major breakthrough in the construction of the tunnel of the Sword Li Expressway Four -standard Project.

The right range of the Yanliangshan Tunnel goes through smoothly

According to the project manager Qu Zhifu, the imported from the Yanliangshan Tunnel is located in Leidangtang, Tangbian Village, Nantian Town, south of Qianxian, and has a high pressure on environmental water protection and great environmental protection pressure. The left line of the tunnel is 1152m and the right line is 1145m. The Yanliangshan Tunnel is not only a key line to control the construction of the left bridge of Liangshan exit and the construction of the Nanmengxi Special Bridge, but also the beam channel to control the bridge of the sword on the side of the sword on the south Bridge of the South Mengxi. Therefore, the Yanliangshan Tunnel is also a control project of 4 targets. Under the leadership of the project team, all participating staff drummed the courage to "break into", took out the energy of "fighting", and the "real" motivation, which made the right line of the Yanliangshan tunnel penetrate in advance. Production has entered a decisive battle.

The Remote Echo of the Remaining of the Ryliang Mountain Tunnel

Since the construction of the Yanliangshan Tunnel in December 2020, the project department has paid close attention to the construction plan, organized the construction process efficiently, and adopted technical guarantee measures such as advanced geological forecasting, monitoring measurement measurement, and successively overcome the smooth layer of the siberite in the southern Guizhou area. Technology problems such as shallow geological landslides; strictly control the process of the process, continuously optimize the combination of processes, promote the parallel operations of each process, and continuously optimize the construction plan. In response to unpredictability and the characteristics of surrounding rocks, the project department has repeatedly organized light surface blasting technology many times. The discussion was based on the depth of the drilling of the tunnel light explosion, the angle, the distance of the eye, and the amount of medicine, and organized the technical personnel to hold a seminar to discuss and apply it in the tunnel construction.

At the same time, during the construction process, the project department adhered to the principles of "predicting prediction, governance, short excavation, strict injection of pulp, strong support, early closure, diligent measurement measurement" in advance, scientific organizations, and continuously optimizing the allocation of resource allocation to overcome it to overcome it. Various problems encountered in the construction of mountain tunnel construction materials in difficulties in construction, and all participants have gone through the hard work of many nights to achieve the goal of safe and smooth the right line of the Rock Liangshan Tunnel.

The total length of the Jianhe to Liping highway is about 74.4 kilometers, with a total of 8 standard sections. The total contracting of 3P mode is used. Among them, the fourth bid section line of the Jianli Expressway is about 7.9 kilometers, including 6 bridges and 3 tunnels. Nanda Town. As an important tourist channel in the famous tourist area of ​​Southeast Guizhou, it is a pearl embedded in the tourist channel in the famous scenic area of ​​Southeast Guizhou. Construction of quality engineering, practice the concept of green construction, will build "environmental protection engineering, green engineering" and safety quality progress management, and prevent and control of the epidemic. , Green Line, Harmony Line, and Rich Line will definitely open a new page in the history of the traffic development of Jianhe County, Jinping County, and Liping County, and drive the economic development along the line.
