Construction method for quickly dismantling box girder bridge without support
The invention relates to the technical field of bridge demolition construction, in particular to a construction method for quickly demoliting a box girder bridge without a support. The method comprises the following steps of: (A) temporarily anchoring a pier; (B) cutting and removing a flange plate; (C) cutting and removing a top plate and a bottom plate; (D) cutting and removing a residual web part; (E) cutting and removing a pier anchoring section; (F) performing column removal. According to the construction method for quickly demoliting a box girder bridge without the support, temporary consolidation measures are taken at the bridge piers, then the girder bridge is reasonably cut and dismantled, the process of arranging the support is omitted in the dismantling process, the constructionperiod is shortened, the construction efficiency is improved, the construction cost is reduced, and the construction method can be popularized in actual engineering.
本发明涉及桥梁拆除施工技术领域，具体涉及一种无支架快速拆除箱梁桥的施工方法，包括以下步骤：(A)桥墩临时锚固；(B)切割拆除翼缘板；(C)切割拆除顶板以及底板；(D)切割拆除剩余腹板部分；(E)切割拆除桥墩锚固段；(F)立柱拆除。本发明提供一种无支架快速拆除箱梁桥的施工方法，通过在桥墩处设置临时固结措施，然后合理的对梁桥进行切割拆除，在拆除过程中免去设置支架这一过程，缩短了施工工期，提高了施工效率，降低了施工成本，可以在实际工程中推广。
