Prefabricated reinforced concrete bottom plate assembly and forming process
The invention discloses a prefabricated reinforced concrete bottom plate assembly. The prefabricated reinforced concrete bottom plate assembly comprises leg block plate pieces adaptive to the two sidewalls of a tunnel, and a bottom plate block piece is embedded between the two leg block plate pieces. The leg block plate pieces comprise side bracing segments parallel to and abutting against the two side walls of the tunnel and a bottom bracing segment parallel to the bottom of the tunnel, inserting bars connected with an upper reinforcing mesh in an adaptive mode are arranged at the tops of the side bracing segments, the top surfaces of the bottom bracing segment is tightly connected with the top surface of the bottom block plate piece to form an upper supporting surface of the prefabricated reinforced concrete bottom plate assembly, and the bottom block plate piece is detachably connected with the leg block plate pieces through fastening pieces. The prefabricated reinforced concrete bottom plate assembly can effectively improve the tunnel lining construction efficiency, and ensure the health of construction personnel. The invention further discloses an egg-shaped tunnel lining process of the prefabricated reinforced concrete bottom plate assembly.
本发明公开了一种预制钢筋砼底板组件，包括分别与隧洞两侧壁适配的脚块板件，两所述脚块板件之间嵌装有底块板件，所述脚块板件包括与隧洞两侧壁平行布置并抵接的侧撑段以及与隧洞底部平行布置的底撑段，所述侧撑段的顶部设置有与上部钢筋网适配连接的插筋，所述底撑段的顶面与所述底块板件的顶面紧密相接形成所述预制钢筋砼底板组件的上支撑面，所述底块板件与所述脚块板件间通过紧固件可拆装地相连接。该预制钢筋砼底板组件能够有效提高隧洞衬砌施工效率，并保证施工人员健康。本发明还公开了一种应用上述预制钢筋砼底板组件的蛋形隧洞衬砌工艺。
