Temporary support for dismantling urban viaduct in complex environment and dismantling method
The invention relates to the technical field of viaduct reconstruction, in particular to a temporary support for dismantling an urban viaduct in a complex environment and a dismantling method. Step 2, paving a bridge deck and removing guardrails; thirdly, a beam bottom support is constructed; fourthly, the flange plates are cut and dismantled in a segmented mode; fifthly, the beam body is cut and dismantled in a segmented mode; sixthly, the pier column is cut and dismantled in a segmented mode; the viaduct has the beneficial effects that the support assemblies for supporting the viaduct body are arranged below the viaduct body, the viaduct body is cut into multiple sections through the rope saw, the cutting parts are aligned to the support assemblies, and the protective baffles are arranged between every two vertically adjacent support assemblies, so that falling objects generated by cutting can be collected, later cleaning can be facilitated, and the working efficiency is improved. The steel trestle hoisting platform is arranged on the side face of the viaduct body and used for hoisting and dismantling the cut viaduct, so that the construction difficulty is reduced, and the protection effect on the river channel environment is improved.
本发明涉及高架桥改建技术领域，具体为一种复杂环境下城市高架桥拆除用临时支架及拆除方法，具体包括以下步骤：步骤一、施工准备；步骤二、桥面铺装、护栏拆除；步骤三、梁底支架施工；步骤四、翼缘板分段切割拆除；步骤五、梁体分段切割拆除；步骤六、墩柱分段切割拆除；有益效果为：通过在高架桥本体的下方设置有对其支撑的支架组件，利用绳锯将高架桥本体切割成多段，且切割部位与支架组件对齐，竖向相邻的两个支架组件之间设置有防护挡板，可对切割产生的掉落物进行收集，可便于后期清理，在高架桥本体的侧面设置钢栈桥吊装平台，用于对切割后的高架桥进行吊装拆除，从而降低施工难度，且提高了对河道环境的保护效果。
