B102 OU Schmerzke, FL Noise barriers
Information on the type and scope of the construction project
The two noise barriers to be erected will be erected in combination with noise barriers along the new bypass and will be manufactured as steel / reinforced concrete structures.
Due to the subsoil conditions, the structures are deep-grounded on bored piles with a diameter of 75 cm and a length of 4.5 m. The bored piles are to be made of reinforced concrete C30/37 with reinforcing steel B500B.
The main parameters of the noise barriers to be erected are:
LA 03:
Impact: Wind zone 2 according to DIN EN 1991-1-4
Differential height (up to OK LSW): < 4.65 m
Segmenthöhe LSW-Element: 0,05 m - 3,00 m
Number of segments: 39 pcs.
Total length: 125.5 m
Noise barrier - viewing area: 498.5 m²
Absorption group: highly absorbent
LA 04:
Impact: Wind zone 2 according to DIN EN 1991-1-4
Differential height (up to OK LSW): < 5.35 m
Segmenthöhe LSW-Element: 0,05 m - 3,00 m
Number of segments: 73 pcs.
Total length: 230.5 m
Noise barrier - viewing area: 972,0 m²
Absorption group: highly absorbent
Essentially, the following work must be carried out for the production of the noise barriers:
LA 03:
Reinforcing steel posts: 8 t
Reinforcing steel foundation: 7 t
Concrete base: 100 m²
Concrete wall elements: 435 m²
Bohrpfahllänge: 104 m
LA 04:
Reinforcing steel posts: 18 t
Reinforcing steel foundation: 13 t
Concrete base: 232 m²
Concrete wall elements: 838 m²
Bohrpfahllänge: 189 m
