Prefabricated small box girder prestress engineering construction method for intelligent expressway
The invention discloses a prefabricated small box girder prestress engineering construction method for an intelligent expressway. The prefabricated small box girder prestress engineering construction method specifically comprises the following steps that S1, construction lofting is conducted; s2, bottom and web steel bars are bound; s3, bottom and web prestressed pipelines are installed; the pipeline installation is synchronously carried out along with the prefabricated small box girder steel bar binding; s4, a formwork is installed; s5, top plate reinforcing steel bars are bound; s6, a top plate prestress pipeline is installed; s7, mounting an anchor plate; after the pipeline is installed and before the beam end formwork is sealed, an anchor plate is installed, and the anchor plate and the prestressed pipeline are perpendicularly installed; s8, an end formwork is installed; compared with a traditional prefabricated segmental beam, the number of segments is greatly reduced, and construction is simplified; an internal prestress mode is adopted, the structural durability can be guaranteed by controlling the grouting quality, the structural maintenance cost is reduced, and the method has the advantages of being safe and convenient to construct, good in feasibility and high in reliability.
本发明公开了一种用于智慧快速路的预制小箱梁预应力工程施工方法,预制小箱梁预应力工程施工方法具体包括以下步骤:S1:施工放样;S2:绑扎底、腹板钢筋;S3:安装底、腹板预应力管道;管道安装随预制小箱梁钢筋绑扎同步进行;S4:安装模板;S5:绑扎顶板钢筋;S6:安装顶板预应力管道;S7:锚板安装;管道安装完成后,梁端模板封模前,即进行锚板安装,锚板与预应力管道垂直安装;S8:安装端头模板;本发明相对于传统的预制节段梁,大幅减少了节段数量,简化施工;本发明采用体内预应力的形式,可通过控制压浆质量保证结构耐久性,降低结构维护费用,具有施工安全方便,可行性好,可靠性高。
