Support mounting method for high-speed railway box girder
The invention provides a support installation method for a high-speed railway box girder. The support installation method comprises the following steps that S1, beam bottom support steel plates are pre-buried in the two sides of a beam end bottom die of the box girder; s2, after the box girder is prefabricated and formed, a girder support is installed at the bottom of the box girder; the method comprises the following steps: S1, mounting a bridge pier support cushion stone template, S2, mounting a bridge pier support cushion stone template, S3, mounting a support cushion stone template, S4, positioning a box girder on the support cushion stone, S5, introducing slurry into the support cushion stone template and a bolt preformed hole thereof through a grouting device, and S6, dismounting a temporary support after the slurry is injected into the bridge pier support cushion stone and the support bolt hole to reach the design strength, so that the box girder is positioned on the top surface of the support cushion stone, and finally mounting the bridge pier support cushion stone template. A support steel plate is embedded in the beam end bottom die, the design position of the beam support is accurately positioned, and checking of technicians every time is reduced. The grouting space is formed in the gap between the beam support and the support padstone through the support padstone formwork, grouting is conducted on the interior of the support padstone formwork through the grouting device, and the durability of a concrete structure is improved.
本发明提供一种高速铁路箱梁的支座安装方法，包括以下步骤：步骤S1，在箱梁的梁端底模两侧位置预埋梁底支座钢板；步骤S2，待箱梁预制成型后，在箱梁底部安装梁支座；步骤S3，进行支座垫石模板的安装，步骤S4，将箱梁就位于支座垫石上，步骤S5，将浆料通过灌浆装置引入支座垫石模板及其螺栓预留孔内，步骤S6，待桥墩支座垫石和支座螺栓孔注入浆料达到设计强度后，拆除临时支撑，使箱梁就位于支座垫石顶面上，梁端底模预埋支座钢板，精准定位梁支座设计位置，减少技术人员每次校核。通过支座垫石模板对梁支座和支座垫石之间的缝隙形成注浆空间，利用灌浆装置对支座垫石模板内部进行灌浆，提高了混凝土结构的耐久性。
