Bridge guardrail transformation structure of UHPC permanent formwork
The invention discloses a bridge guardrail transformation structure of a UHPC permanent formwork, and belongs to the technical field of bridge guardrails, the bridge guardrail transformation structure comprises an old guardrail wall body, original guardrail steel bars are embedded in the old guardrail wall body, a plurality of groups of drill holes are uniformly distributed in the top of the old guardrail wall body, upper embedded steel bars are arranged in the drill holes, and upper embedded steel bars are arranged in the upper embedded steel bars. A guardrail transformation layer and a UHPC formwork are arranged on the old guardrail wall body, the guardrail transformation layer is arranged on the upper embedded steel bars in a sleeving mode, the guardrail transformation layer covers the top face and the head-on collision face of the old guardrail wall body, the UHPC formwork is arranged on the guardrail transformation layer in a sleeving mode, pouring holes are formed in the guardrail transformation layer and the UHPC formwork, and the UHPC formwork is arranged on the top face and the head-on collision face of the old guardrail wall body in a sleeving mode. And the UHPC formwork is fixedly connected with an old guardrail wall through high-strength bolts. The bridge guardrail transformation structure of the UHPC formwork has the advantages that the strength of the guardrail is enhanced, the original guardrail structure is effectively utilized, and the influence on traffic is reduced.
本发明公开了一种UHPC永久模板的桥梁护栏改造结构，属于桥梁护栏技术领域，包括旧护栏墙体，所述旧护栏墙体内部埋设有原护栏钢筋，所述旧护栏墙体顶部均匀布设有多组钻孔，所述钻孔内部设置有上部植筋，所述旧护栏墙体上设置有护栏改造层和UHPC模壳，所述护栏改造层套设于上部植筋上，所述护栏改造层覆盖于旧护栏墙体的顶面和迎撞面上，所述UHPC模壳套设于护栏改造层上，所述护栏改造层和UHPC模壳上均开设有浇筑孔，所述UHPC模壳通过高强螺栓与旧护栏墙体固定连接，本发明公开的一种加强护栏强度，有效利用原护栏结构，并减少对交通的影响的UHPC模壳的桥梁护栏改造结构。
