In-tunnel abutment and side span closure construction method
The invention discloses an in-tunnel abutment and side span closure construction method, and relates to the field of closure construction in structural corrosion medium-low mountain and valley landforms, the in-tunnel abutment and side span are located in the structural corrosion medium-low mountain and valley landforms, and the method comprises the following steps of: gradually closing the closure sections of the side span in the direction of closing the closure sections of the side span section by section; respectively pouring to form a side span straight line section of the in-tunnel abutment and a side span straight line section of the out-tunnel abutment; before the side span closure section is closed, a bottom die, a steel bar, a prestressed steel bar, a side die and an inner die are installed, and a side span closure section template is formed; concrete is poured into the side span closure section formwork, and the two beams of bottom plate prestress are tensioned through a stiff framework; and concrete of the side span closure section is poured through hanging basket equipment, and in-tunnel abutment and side span closure construction is completed. According to the method, the stiff framework is used for tensioning the prestress of the two beams of bottom plates, and the hanging basket equipment is used for pouring the concrete of the side span closure section, so that the stability and the construction quality of the closure section are improved, and the construction efficiency is improved.
本发明公开了一种洞内桥台及边跨合拢施工方法，涉及构造溶蚀中低山峡谷地貌中的合拢施工领域，所述洞内桥台及边跨位于构造溶蚀中低山峡谷地貌中，所述方法包括：逐段向边跨合拢段靠拢的方向，分别浇筑形成所述洞内桥台的边跨直线段和洞外桥台的边跨直线段；在所述边跨合拢段合拢前，安装底模、钢筋、预应力钢筋、侧模和内模，形成边跨合拢段模板；向所述边跨合拢段模板浇筑混凝土，并利用劲性骨架张拉两束底板预应力；利用挂篮设备浇筑所述边跨合拢段的混凝土，完成所述洞内桥台及所述边跨合拢施工。本发明通过利用劲性骨架张拉两束底板预应力，并利用挂篮设备浇筑所述边跨合拢段的混凝土，提高了合拢段的稳定性和施工质量，且提高了施工效率。
