Introduction to the characteristics of Enlai expressway?

Enlai expressway is located in Enshi City, Xuanen County and laifeng county, Enshi Prefecture. The surrounding towns and villages mainly include Hexagonal Pavilion Office, Bajiao Township, Jiaoyuan Town, Xiaoguan Township, Gaoluo Township, Shadaogou Town and Xiangfeng Town. The construction of the project will greatly promote the development of towns along the line. CBI Zhong Da Consulting Company introduced the characteristics of Enlai expressway as follows:

Enlai expressway is characterized by complex terrain and unfavorable geological phenomena.

The project is located in low mountains, middle and low mountains and hilly areas in southwest Hubei. The mountains are undulating, patchwork and overlapping. Geomorphological cutting is more serious, and the terrain conditions are more complicated. Affected by regional structure, stratum lithology, topography and hydrogeology, there are some unfavorable geological phenomena such as karst, collapse, rock pile and landslide.

The characteristics of Enlai expressway are rich in resources, and the protection of resources is of great significance.

Resource enrichment in the project area. Enshi Prefecture is known as "the forest in western Hubei", "seed gene bank" and "Chinese medicine bank". There are also rich mineral resources and water resources; There are also many unique tourism resources, such as green mountains and green waters, grotesque caves, colorful and unique cultural landscapes, world-famous Enshi Grand Canyon architecture, Qingjiang Broken Beach, Qizimeishan in Xuanen County, a national nature reserve, Pingbaying in National Forest Park, and the ruins of Tangya Tusi Imperial City in Xianfeng. Before the route scheme is selected, the investigation of overlying mineral resources should be strengthened and avoided as much as possible. Project construction should try not to destroy natural water resources and tourism resources.

The characteristics of Enlai expressway-the mountain microclimate in the project area is diverse, which has great influence on design and construction.

The terrain of the project area is complex and the mountain microclimate is diverse. Due to the height change, the vertical difference is prominent, forming a three-dimensional climate. There are many disastrous weather in summer, and there are often heavy rains and heavy rains. Among them, rainstorm and heavy rainfall can cause geological disasters such as landslides and collapses. The local elevation of this contract section exceeds 1000m, and there is an ice fog area. In the design, we should focus on slope protection and waterproof and drainage design of subgrade bridge to ensure the safety management in the later construction and operation period.

The characteristics of Enlai expressway-the area where the route passes is relatively high in elevation difference and long in longitudinal slope, which has a great influence on the driving safety of vehicles.

The route of this contract section is basically in the same corridor as the national highway G209, and part of it is in the same corridor as the national highway S232. Due to the corridor conditions, long sections of local sections continuously and frequently cross national highways and provincial highways, which involves the rerouting of national highways and provincial highways. In the design process, the construction organization design should be done well, and corresponding measures should be taken during the construction to ensure smooth traffic.

The characteristics of Enlai Expressway-obvious overlap between the route and the provincial corridor, and great traffic interference.

The lowest elevation of the route corridor in this project section is about 500m at Youshui River in laifeng county, and the highest elevation is about 850m at the entrance of Dajiang Branch Extra-long Tunnel. The height difference of the route needs to be overcome, and the average longitudinal slope of some sections is relatively large. The scheme design should pay attention to traffic safety and minimize traffic accidents.
