Culvert lengthening structure and lengthening method thereof
The invention relates to the technical field of bridge and culvert construction, in particular to a culvert lengthening structure and a lengthening method thereof.The culvert lengthening structure comprises existing culvert sections, newly-built culvert sections, retaining walls and supporting structures; the axis of the cross section of the newly-built culvert section coincides with the axis of the cross section of the existing culvert section, and a gap is formed between the newly-built culvert section and the existing culvert section. The retaining walls are symmetrically arranged on the two sides of the newly-built culvert section. The supporting structure is arranged between the existing culvert section and the newly-built culvert section, and the two ends of the supporting structure are connected with the existing culvert section and the retaining wall correspondingly. The bending resistance stress of a large cantilever of the protection pile is adjusted to be the small-interval bending resistance stress of the soil retaining plate and the axial stress of the supporting structure, and the problem that a culvert with the large protection depth is difficult to lengthen is solved.
本发明涉及桥涵施工技术领域，涉及一种涵洞接长结构及其接长方法，所述结构包括既有涵节、新建涵节、挡墙及支撑结构；所述新建涵节的横截面轴线与既有涵节的横截面轴线重合，所述新建涵节与所述既有涵节之间设置有间距；所述挡墙对称设置在所述新建涵节的两侧；所述支撑结构设置在既有涵节与新建涵节之间，所述支撑结构的两端分别与所述既有涵节连接和所述挡墙连接，本发明通过对称设置的水平支撑结构替换现有技术中的防护桩，将防护桩的大悬臂抗弯受力调整为挡土板的小间距抗弯受力与支撑结构的轴向受力，解决了防护深度较大的涵洞接长困难的问题。
