Multifunctional composite bridge deck longitudinal splicing structure and construction method thereof
The invention relates to the technical field of old concrete bridge longitudinal splicing structures, in particular to a multifunctional composite bridge deck longitudinal splicing structure and a construction method thereof. The technical key points are as follows: the splicing structure comprises a polyurethane anti-skid wearing layer paved on the surface functional layer from top to bottom; the anti-crack enhanced high polymer elastic and toughened body is laid on the upper surface layer; the invention discloses a self-adhesive hyperbranched toughened epoxy asphalt polyester glass fabric. The drainage liquid-permeable high polymer elastic and toughened body is laid on the lower surface layer; a carbon fiber reinforced epoxy resin laminate; the splicing structure is arranged in a notch formed by reverse excavation of asphalt pavement of an original bridge deck. The positions, making contact with the splicing structure, of the bottom and the two sides of the notch are coated with a high-resolution bullet firmware interface binder. According to the bridge deck longitudinal splicing, the drainage type asphalt pavement structure is introduced, and the pavement damage caused by water partition between old concrete bridge deck pavement layers in a traditional disposal mode is effectively solved.
本发明涉及老混凝土桥梁纵向拼接结构技术领域，尤其涉及一种多功能复合式桥面纵向拼接结构及其施工方法。其技术要点如下：拼接结构，从上到下包括：铺筑于表面功能层的聚氨酯抗滑磨耗层；铺设于上面层的抗裂增强型高聚物弹韧体；自粘式超支化增韧型环氧沥青聚酯玻纤布；铺设于下面层的排水透液型高聚物弹韧体；碳纤维增强环氧树脂层合板；所述拼接结构设置在原桥面沥青铺装反向开挖形成的槽口内；所述槽口的底部和两侧与拼接结构接触的位置涂布高分子弹韧体界面粘结剂。本发明提供的桥面纵向拼接通过引入排水式沥青路面结构，有效解决传统处置方式隔断旧混凝土桥面铺装层间水隔断导致的铺装病害。
