Mountainous area high-pier bridge step dislocation construction method
The invention discloses a mountainous area high-pier bridge step dislocation construction method. The method comprises the following steps: 1, a hanging basket truss walks to N sections, and a mounting formwork binds N sections of bottom plate steel bars and N-1 sections of top plate steel bars; 2, concrete of N sections of bottom plates and N-1 sections of top plates is poured, and meanwhile, installation construction of N + 1 sections of folded webs is carried out by utilizing the hanging basket self-hoisting folded webs; and 3, the hanging basket truss walks to N + 1 sections, the prestressof the top plate of the N-1 sections is tensioned, and circulation of the next section is conducted in a reciprocating mode in sequence. According to the construction method disclosed by the invention, one operation area is expanded to three operation areas; the three sections are independently and synchronously constructed; reasonable procedure connection and no interference are achieved, meanwhile, the hanging basket self-hoisting folded webs are used for installation and construction of the N + 1 sections of folded web plates, installation and hoisting of the folded webs of the mountainousvalley high pier bridge are facilitated, the limitation of a traditional construction method on a bridge construction site is overcome, installation of the folded webs is facilitated, meanwhile, theconstruction cost can be saved, and the construction efficiency can be improved.
本发明公开了一种山区高墩桥梁台阶错位施工方法，包括以下步骤：步骤一、挂篮桁架行走到N节段，安装模板绑扎N节段底板钢筋和N‑1节段顶板钢筋；步骤二、浇筑N节段底板和N‑1节段顶板混凝土，同时利用挂篮自吊装折腹板进行N+1节段折腹板安装施工；步骤三、挂篮桁架行走到N+1节段，张拉N‑1节段顶板预应力，依次往复进行下一节段的循环。本发明中的施工方法把1个作业区扩大到了3个作业区，3个节段单独同步施工，工序衔接合理，互不干扰，同时利用挂篮自吊装折腹板进行N+1节段折腹板安装施工，方便了山区峡谷高墩桥梁折腹板安装吊运，且克服了传统施工方法对桥梁施工场地的局限性，便于折腹板的安装，同时能够节约施工成本和提高施工效率。
