Reinforcing method of hollow plate girder bridge
The invention relates to a reinforcing method of a hollow plate girder bridge. The reinforcing method comprises the following steps that an original pavement layer on a hollow plate and original concrete in a hinge joint are dismantled; a hinge joint bottom die and hinge joint reinforcing ribs are installed, one part of each hinge joint reinforcing rib is located in the hinge joint, the other partof each hinge joint reinforcing rib is located above the hinge joint, and concrete is poured into the hinge joints to form hinge joint concrete; a first connecting piece is arranged between every twoadjacent hollow plates, and the two ends of the first connecting piece are implanted into the two corresponding adjacent hollow plates respectively; a reinforcing mesh is arranged on the hollow plate, and the reinforcing mesh is bound with the first connecting piece; the concrete is poured on the hollow plates to cover portions, located above the hinge joints, of the reinforcing mesh, the first connecting piece and the hinge joint reinforcing ribs, and a concrete pavement layer is formed; and an asphalt pavement layer is paved on the concrete pavement layer. Reinforcing quality can be guaranteed, maintenance difficulty and cost are reduced, and meanwhile problems that a structural appearance is affected by reinforcing the hinge joints through a bonding steel plate, and the steel plate needs to be maintained in a later period are solved.
本申请涉及一种空心板梁桥的加固方法，其包括如下步骤：拆除空心板上的原铺装层，以及铰缝中的原混凝土；安装铰缝底模以及铰缝加强筋，并使铰缝加强筋一部分位于铰缝内，另一部分位于铰缝以上，向铰缝中灌注混凝土，以形成铰缝混凝土；在相邻两个空心板之间布设第一连接件，使第一连接件的两端分别植入相邻两个空心板中；在空心板上布置钢筋网，并与第一连接件绑扎；在空心板上浇筑混凝土，以覆盖钢筋网、第一连接件和铰缝加强筋位于铰缝以上的部分，并形成混凝土铺装层；在混凝土铺装层上铺设沥青铺装层。本申请不仅可以保证加固质量，降低养护维修难度和费用，同时避免了采用粘贴钢板加固铰缝影响结构外观、且钢板后期需要维护的问题。
