Construction method for special-shaped bridge supporting formwork
The invention discloses a construction method for a special-shaped bridge supporting formwork, and relates to the technical field of bridge construction, and the construction method comprises the following steps: supporting formwork foundation construction: filling a layer of sand gravel with the thickness of 30cm on the top surface of backfilled shale, leveling, then uniformly hardening by adopting C25 concrete with the thickness of 15cm, and covering and curing by adopting a film; the two sides of a foundation cushion layer of the supporting formwork are wider than the erecting edge of the support by not less than 1.0 m, and pouring is conducted according to the erecting range of the support in the cushion layer range; anti-scour walls are arranged on the upstream side and the downstream side of the island-building cofferdam to prevent flood from passing through the support when the flood is changed into the ditch and cannot be effectively drained; measuring and setting out; mounting a supporting formwork; laying a template; forming a template: filling gaps, caused by curves, of the template with processed battens, and sticking the gaps with instant stickers to prevent slurry leakage; the supporting formwork can adapt to the shape that the bottom of a bridge is a quadratic parabola, and installation is more convenient.
本发明公开了一种用于异型桥梁支撑模架的施工方法，涉及桥梁施工技术领域，采用以下步骤：支撑模架基础施工：在回填的页岩顶面上再填筑一层30cm厚砂砾石整平后再统一采用15cm厚C25混凝土硬化，采用薄膜覆盖养生；支撑模架基础垫层两侧宽出支架搭设边缘不少于1.0m，垫层范围视支架搭设范围进行浇筑；在筑岛围堰上下游侧设置防冲刷墙，防止洪水改移沟渠无法有效排水时，洪水从支架处通过；测量放线；支撑模架安装；模板铺设；模板成型：模板因曲线造成的缝隙,用加工后的木条填塞,再用即时贴贴缝,以防漏浆；使得该支撑模架能够适应桥梁底部是二次抛物线的造型，安装更加方便。
