Steel bridge deck pavement bottom layer structure suitable for heavy traffic and construction method
The invention discloses a steel bridge deck pavement bottom layer structure suitable for heavy traffic and a construction method, and relates to the field of bridge engineering. Stiff fiber reinforcing strips and fiber grids are arranged at the bottom of the steel bridge deck pavement structure, epoxy resin filling holes are filled with epoxy resin in the epoxy macadam layer, and meshes of the fiber grids and grids of the stiff fiber reinforcing strips are filled with the epoxy resin and macadam in the epoxy macadam layer; on one hand, the flexural tensile strength and flexural tensile fatigue resistance of the bottom of the pavement structure are greatly enhanced, and on the other hand, the shear strength of the bottom of the steel bridge deck pavement structure and the steel plate is improved, so that the damage of integral shear delamination failure of the steel bridge deck pavement bottom under the action of heavy traffic is effectively avoided.
本发明公开一种适用于重载交通的钢桥面铺装底层结构及施工方法，涉及桥梁工程领域。在钢桥面铺装结构底部设置劲性纤维增强条与纤维格栅，环氧碎石层中的环氧树脂填充环氧树脂填充孔，环氧碎石层中的环氧树脂和碎石填充纤维格栅的网孔和劲性纤维增强条的网格，一方面大幅增强铺装结构底部的抗弯拉强度及抗弯拉疲劳能力，另一方面提升钢桥面铺装结构底部与钢板的抗剪切强度，有效避免在重载交通作用下，钢桥面铺装底部发生整体性剪切脱层失效的病害。
