Bridge road provided with combined side guardrails and construction method of bridge road
The invention discloses a bridge road provided with combined side guardrails and a construction method of the bridge road, and relates to the technical field of bridge engineering construction. The bridge road comprises a beam body and the combined side guardrails; the combined side guardrails comprise a plurality of guardrail units which are sequentially connected in the bridge direction, each guardrail unit comprises an outer side guardrail and an inner side guardrail, wherein each outer side guardrail is a prefabricated guardrail of an integrated structure, at least two cantilever supportsare embedded in the outer side guardrail, and the two cantilever supports are both connected to the upper surface of the beam body in a hung manner, so that the outer side guardrail can be suspended on the side of the beam body; and each inner side guardrail is a cast-in-place guardrail, the outer side faces of the inner side guardrails are attached to the inner side faces of the outer side guardrails, the lower surfaces of the inner side guardrails are attached to the upper surface of the beam body, and the inner side guardrails are connected to the cantilever supports in wrapping and hangingmanners. According to the bridge road, a semi-prefabricated and semi-cast-in-place manner is adopted, the prefabricated outer side guardrails serve as pouring formworks of the cast-in-place inner side guardrails, the combined side guardrails are installed on the sides of the bridge road, the problem that outer formworks of the side guardrails are difficult to install is solved, and the construction efficiency is effectively improved.
本申请公开一种安装有组合边护栏的桥梁公路及其施工方法，涉及桥梁工程建筑技术领域，桥梁公路包括：梁体；组合边护栏，其包括若干个沿桥向依次相连的护栏单元，护栏单元包括：外侧护栏，其为一体结构的预制护栏，外侧护栏中预埋有至少两个悬臂支撑，两个悬臂支撑均挂接在梁体的上表面，以使外侧护栏悬设在梁体的边侧；内侧护栏，其为现浇护栏，内侧护栏的外侧面与外侧护栏的内侧面贴合设置，内侧护栏的下表面和梁体的上表面贴合设置，且内侧护栏包覆挂接在悬臂支撑上。本申请采用半预制半现浇的形式，将预制的外侧护栏作为现浇的内侧护栏的浇注模板，在桥梁公路的边侧安装组合边护栏，解决了边护栏的外模安装困难的难题，有效提高施工效率。
