Prefabricated and assembled integrated guardrail based on UHPC connection and construction method
The invention discloses a prefabricated and assembled integrated guardrail based on UHPC connection and a construction method, and belongs to the technical field of highway bridge guardrail devices.The prefabricated and assembled integrated guardrail comprises a prefabricated concrete guardrail body, a post-pouring UHPC part and a longitudinal connecting part, and a post-pouring UHPC groove is formed in the bottom of the prefabricated concrete guardrail body; the post-pouring UHPC parts are located in the post-pouring UHPC grooves and extend out of the prefabricated concrete guardrails to be in an L shape, the longitudinal connecting parts are located between the adjacent prefabricated concrete guardrails, and the post-pouring UHPC parts and the longitudinal connecting parts are integrally formed in a pouring mode. UHPC connection is adopted, the connection mode is simple, convenient and rapid, and the strength of a connection seam is high; and meanwhile, UHPC connection is adopted in the longitudinal direction, the multiple segments of prefabricated concrete guardrails bear impact force together, and the possibility that the guardrails are stressed independently is avoided.
本发明公开一种基于UHPC连接预制装配一体化护栏及施工方法，属于于公路桥梁护栏装置技术领域，包括：预制混凝土护栏、后浇UHPC部和纵向连接部，所述预制混凝土护栏底部设置有后浇UHPC槽，所述后浇UHPC部位于所述后浇UHPC槽中并伸出所述预制混凝土护栏呈L形，所述纵向连接部位于在相邻所述预制混凝土护栏之间，所述后浇UHPC部和所述纵向连接部浇筑一体化成型。本发明采用了UHPC连接，连接方式简便，快捷，连接接缝强度高；同时纵向采用UHPC连接，多片节段预制混凝土护栏共同承受撞击力，避免护栏单独受力的可能性。
