Correspondent Zhai Shanshan Chen Jing Wang Yan

Recently, the Chaijia Tunnel of the Chaijia Tunnel of the Shanxi Province of Hubei National Expressway Shanxi Province has successfully connected. The builders of the 22nd Bureau of China Railway lasted for 635 days to fight hard, and successfully opened up the "lifeline" of Shuoshen high -speed construction. At this point, the construction of the Shuoshen high -speed project has shifted from the construction stage of the civil construction to the pavement construction phase, laying a solid foundation for the completion of the entire line.

The route of the second contract of Shuoshen Expressway is 14.355 kilometers in length, with a design speed of 100 kilometers per hour, and a two -way four -lane. It consists of two tunnels, 7 bridges and roadbeds. Chaijiayu Tunnel is located in Chaijia Village, Shenchi County. It is a double -line separation tunnel. The left line is 1898 meters long and the right line is 1870 meters long. The geological conditions are complicated. Essence

The Chaijiayu Tunnel is the heavy difficulty of the Shuoshen highway project. The geological conditions are complicated, the rock layer inclination is close to the level. The ability is extremely poor, it is easy to collapse, high safety risks, and difficult construction organizations. The project department strictly follows the eighteen characters of "Guan Chao, strictly injection, short excavation, strong support, early closed, and diligent measurement". Perform advanced forecasts, strictly control the excavation ruler, constantly adjust the form of advanced support, reduce the disturbance of the surrounding rocks and the damage of the ecological environment around the surface, and ensure the quality of tunnel excavation molding. The entire construction process has achieved zero production safety accidents, and the project department has completed the tunnel penetration tasks with high standards, high efficiency, and high quality.

Construction discussion of construction plan

The construction area of ​​the project is relatively scarce, and artificial planting is the most important type of vegetation in the road corridor belt, accounting for about 90%of the total vegetation coverage in the area, and the natural resources along the line are scarce, and the requirements for environmental protection construction are extremely high. In order to avoid the influence of the natural environment of the project, the project department has achieved timely control and removal of dust, noise, and waste water at the construction site to achieve green construction and environmental construction roads to ensure the harmonious development of ecological protection and construction.

Shanxi Province Shuocheng to Shenchi section project

Since the construction of the market this year, in the face of the rapid spread of the domestic epidemic, it has led to a difficult situation in the difficulty of entering the field, the project department's advanced planning, scientific deployment, and the implementation of the "point -to -point" entry principle of the enrollment materials and the laborers. Check the itinerary and health code; strengthen the management of on -site personnel, completely eliminate the daily disinfecting of the office area, living area and construction site, strictly control the personnel to go out, enable the "zero contact" of the visitors Control the system, achieve joint prevention and control, adhere to the leadership team, comprehensively and thoroughly arranges the workers to ensure that one person is not leaked. Up to now, the project department has issued more than 100 epidemic prevention and control proposals, and has used WeChat groups and WeChat working numbers to propagate more than 500 epidemic prevention and control information.

It is reported that the Shuoshen Expressway is an important part of the West vertical of the Shanxi Expressway Network's "Four vertical, 15 horizontal and thirty -three units" west, and will open up the "last mile" in the south gate of Shuozhou. After the project is completed and opened to traffic, it will shorten the traffic time of Shuozhou to Luliang and northern Shaanxi. It will be of great significance to promote the exchange of personnel and materials, help the rural revitalization and urban development of the revolutionary old districts, and promote the economic development and transformation and upgrading of the northwestern region of Jin.
