Guardrail construction method and modular UHPC bridge guardrail
The invention provides a guardrail construction method and a modular UHPC bridge guardrail. The reserved anchoring ribs on the edge of the bridge plate are used for clamping the UHPC module, and the UHPC module is fixed to the cast-in-place layer of the bridge floor; and concrete is cast in place through the hollow interlayer of the UHPC module, the protection strength is provided, and the connection strength between the UHPC module and the reserved anchoring ribs is kept. The UHPC module is directly used as the cast-in-place shaping formwork, and the formwork structure does not need to be dismantled. The UHPC module serves as a cast-in-place shaping formwork and does not need to be supported by an external structure, and therefore construction of a bridge pavement layer and a dripping eave cannot be affected in the pouring process of the UHPC module. Therefore, the problems that bridge concrete guardrail construction procedures interfere with one another, the construction period is long, and construction is inconvenient are solved through the hollow UHPC module, the construction technology can be simplified, the construction period is shortened, a mature cast-in-place construction method is replaced, and the bridge operation safety protection requirement is met.
本申请提供一种护栏施工方法及模块化UHPC桥梁护栏。本申请利用桥梁板边缘的预留锚固筋卡接UHPC模块，将其固定在桥面的现浇层上；利用UHPC模块自身中空夹层现浇混凝土，提供防护强度并保持与预留锚固筋之间的连接强度。本申请直接利用UHPC模块作为现浇定型模板，无需对模板结构进行拆除。本申请的UHPC模块作为现浇定型模板无需外部结构提供支撑，因而其浇筑过程也不会影响桥梁铺装层、滴水檐进行施工。由此，本申请通过中空的UHPC模块克服了桥梁混凝土护栏施工工序之间相互干扰、施工周期较长、施工不方便等问题，能够简化施工工艺，节省施工周期，替代成熟的现浇施工方法，满足桥梁运营安全防护需求。
