Brief introduction of engineering

Xuhuai Expressway adopts two-way four-lane design, with a design speed of100 km/h; There are 7 interchanges, 2 service areas, 1 communication monitoring center, 1 parking lot, and 4 connecting lines are also built. A mobilization meeting was held on July 14, 2009, and the commencement order was issued on June 10. The total construction period of the project is 4 years, and it is planned to be completed and opened to traffic in June 20 14.

Design subgrade excavation17.574 million m3, filling17.654.38+08654.38+00000 m3 in Xuhuai expressway; 52 bridges with total length17941m; Among them, there are 2 extra-large bridges (the Yanzidong extra-large bridge on the right is 986m long, and the length on the left is1173 m; Total length of Fenping Bridge 1206m). There are 7 tunnels, with a total length of 2247 1m, of which extra-long tunnel 1 seat (the double tunnel length of Guanhuchong extra-long tunnel is 4944m). The length of main tunnels and bridges accounts for about 32% of the total mileage. Passage 132, culvert and aqueduct 1 14.

The geological conditions along Xuhuai expressway are complicated and the construction environment is difficult. There are more than 30 coal mined-out areas on both sides of the main line; Karst areas are widely distributed, and there are 7 areas with strong karst development. All these have brought great difficulties to our construction, and the project construction management is facing challenges.
