Bridge floor reinforcing pavement layer by adoption of lightweight concrete
The invention provides a bridge floor reinforcing pavement layer by adoption of lightweight concrete and belongs to the technical field of bridge engineering. The pavement is capable of increasing transverse stiffness of an existing hollow hinged plate girder bridge. A lightweight concrete reinforcing layer of 15-20 centimeters is used to replace the original concrete bridge floor payment of the hollow hinged plate girder bridge. Constructional steel bars are configured inside the reinforcing layer and the constructional steel bars are arranged on an upper layer and a lower layer to form reinforcing meshes to increase rigidity of the reinforcing layer; wherein, reinforcing steel bars with diameters of phi16 are adopted in transverse direction of the bridge, distributing steel bars with diameters of phi10 are adopted in longitudinal direction of the bridge, and all the steel bars are arranged in full length and with a interval of 10-15 centimeters. On the premise that dead load action is not increased, the new paved lightweight concrete layer is relied on to effectively increase the transverse stiffness of the existing hollow hinged plate girder bridge and improve load-carrying performance and durability of the bridge.
