Dismantling device and construction method for railway temporary support
The invention relates to the technical field of bridge construction assistance. The invention provides a dismantling device and a construction method for a temporary railway support, and aims to solve the problems that a steel box girder is of a common structural form for a large-span bridge, and during dismantling, a high-voltage line is possibly damaged and great potential safety hazards exist due to the fact that the environment adjacent to a railway business line is relatively complex and swinging is caused during dismantling. According to the dismantling device and construction method, lifting lugs are cooperated with chain blocks to dismantle a temporary support, The lifting lugs are welded to the bottom of a steel box girder and the top face of the support, firm connection is achieved through the chain block, the support is cut and lowered to the top of the bearing platform through the chain block, and then the temporary support is rapidly dismantled through cooperation with hoisting equipment; the temporary support dismantling operation can be completed under the environment that large hoisting equipment cannot be close to construction, and potential safety hazards such as overturning in the dismantling process are avoided.
本发明涉及桥梁施工辅助技术领域；钢箱梁是大跨径桥梁常用的结构形式，拆卸时，由于邻近铁路营业线环境比较复杂，拆除时造成的摆动，很可能会造成高压线路破坏，存在极大的安全隐患，本发明提供一种铁路临时支架的拆除装置及施工方法，通过吊耳和倒链配合拆除临时支架，在钢箱梁底部和支架顶面焊接吊耳，并利用倒链连接牢固，切割支架并由倒链下放至承台顶部，然后与吊装设备配合快速拆除临时支架，能够在大型吊装设备无法临近施工的环境下完成临时支架拆除作业，避免在拆除过程中倾覆等安全隐患。
