Cast-in-place concrete bridge blasting demolition method
The invention discloses a cast-in-place concrete bridge blasting demolition method which comprises the following steps: 1, breaking a working face notch in a bridge floor; 2, erecting an up-down ladder which enters a box girder from the working face notch at the working face notch opening position of the bridge floor; 3, determining the position of a shot hole and equipment arrangement; 4, drilling shot holes; 5, filling explosives; 6, detonating and dismantling; and 7, removing the materials, treating and carrying away. By adopting the technical scheme, the workload of blasting demolition construction is small, and the efficiency is high; after blasting, a demolition object falls on the ground, manual and mechanical crushing and loading are carried out, the safety of constructors can be effectively protected, high-altitude operation and falling accidents are avoided, and safety and reliability are achieved; construction and operation are convenient on the ground, demolition materials after blasting can be rapidly loaded and transported, generally, loading and transporting can be completed within half a day, and influence on normal traffic transportation passing is small.
本发明公开了一种现浇砼桥梁爆破拆除方法，包括以下步骤：1、在桥面上破开工作面槽口：2、在桥面的开工作面槽口位置，搭设从工作面槽口进入箱梁内的上下爬梯：3、确定炮眼的位置及设备布置；4、钻炮眼；5、装填炸药；6、起爆拆除；7、拆除物料处理运走。采用上述技术方案，采用爆破拆除施工的工作量小、效率高；爆破后拆除物落在地面上，进行人工配合机械破碎装运，能有效保护施工人员的安全，避免高空作业及坠落事故的发生，安全可靠；在地面上施工，操作方便，爆破后的拆除物料能快速装运，一般在半天时间内即可完成，对正常交通运输通行的影响很小。
