Beijing Shenyang high speed railway reinforced concrete structure fully enclosed noise barrier project has begun to take shape

Recently, Beijing Shenyang high-speed railway reinforced concrete structure fully enclosed noise barrier project has begun to take shape. The project is located in Jiangtai East Road, Chaoyang District, Beijing, and is undertaken by Beijing railway construction company of China Railway No.6 engineering group. At present, Beijing Shenyang high-speed railway fully enclosed sound barrier substructure construction is coming to an end, and superstructure construction is in progress.

The sound barrier project is a super long and ultra wide arched shell structure of reinforced concrete. It is the first fully enclosed sound barrier project of reinforced concrete structure in China. It has a total length of 1.8 km, a transverse span of 40 m to 80 m, and a height of 15 m. There are 36 structural sections.

The upper structure of fully enclosed sound barrier project adopts prestressed concrete sound absorption hollow plate. The hollow plate with the same area is 60% lighter than the concrete slab, which can absorb sound and has better sound insulation effect.

The fully enclosed sound barrier of reinforced concrete structure of Beijing Shenyang high speed railway belongs to the super high, super wide and super long arched thin shell structure. In the construction, China Railway No.6 Engineering Bureau Group used the integrated system of linear Engineering Railway protective support, effectively solved the structural construction problems between the intermediate column groups, greatly reduced the number of business blockade construction points; applied the new technologies such as primary and secondary beam cast-in-place construction, large-area thin shell and intermediate column group assembly, which made the construction fast, green and environmental friendly, and realized the building structure in railway engineering Innovative application of.
