Hollow slab bridge pavement layer structure and construction method
The invention discloses a hollow slab bridge pavement layer structure and a construction method, which are suitable for design and construction of a hollow slab bridge pavement layer, and are characterized in that the structure consists of three parts, namely bridge deck pavement, self-stress slab ribs and anchoring ribs. Three self-stress plate ribs are transversely arranged at the L/4 position, the L/2 position and the 3L/4 position in the first span pavement layer of the bridge, under the action of the three transverse self-stress plate ribs, rigid connection of hinge joints between hollow slabs on the upper portion of the bridge is enhanced, the transverse transmission bending moment of the hinge joints is improved, the transverse rigidity of the bridge is improved, and therefore the service life of the bridge is prolonged, and the service life of the bridge is prolonged. Compared with a bridge upper structure reinforced by transverse prestress at the bottom of a bridge plate, the self-stress plate rib has the advantages of uniform stress distribution, firm combination with the hollow plate, reasonable stress, simple process, low manufacturing cost, environmental protection and the like.
本发明公开了一种空心板桥梁铺装层结构及施工方法，适用于空心板桥梁铺装层的设计与施工，其特征在于所述的结构由桥面铺装、自应力板肋与锚固筋三部分组成。在桥梁一跨铺装层内的L/4、L/2、3L/4处横向布设了三道自应力板肋，桥梁上部结构在三道横向自应力板肋的作用下，桥梁上部空心板之间的铰缝刚性连接得到了加强，铰缝横向传递弯矩得到提升，提高了桥梁横向刚度，从而延长了桥梁的使用寿命，相比桥梁板底横向预应力加固桥梁上部结构，自应力板肋具有应力分布均匀，与空心板结合牢固，受力合理，工艺简单，造价低，绿色环保等优点。
