Directional blasting demolition method for bridge engineering disease part
The invention discloses a directional blasting demolition method for a bridge engineering disease part. The to-be-reserved beam body and the to-be-disassembled beam body adjacent to the to-be-reserved beam body are cut and separated, and beam plates of the to-be-disassembled beam body are cut and separated; performing water pressure blasting on the to-be-disassembled beam body adjacent to the to-be-reserved beam body; directional blasting is conducted on piers and related cross tie beams between the to-be-demolished beam bodies; the dumping direction is controlled; the to-be-dismantled beam bodies adjacent to the to-be-reserved beam bodies, piers between the to-be-dismantled beam bodies and related cross tie beams are detonated in a networking mode; recycling the reinforcing steel bars and cleaning blasting slag. According to the method, the to-be-disassembled beam body adjacent to the to-be-reserved beam body is subjected to water pressure blasting, the water pressure blasting generates a uniform destructive effect in each space of the beam plate box chamber of the to-be-disassembled beam body, and the influence of large residues on the to-be-reserved beam body or other structures is avoided. By controlling the dumping direction, damage to living facilities around the bridge or injury to constructors caused by blasting demolition is avoided, and later reinforcing steel bar recycling and blasting slag cleaning are far away from resident living quarters.
本申请公开了一种针对桥梁工程病害部位的定向爆破拆除方法。将拟保留梁体与拟保留梁体相邻的拟拆梁体切割分离，并将拟拆梁体的梁板之间切割分离；对拟保留梁体相邻的拟拆梁体实施水压爆破；定向爆破拟拆梁体之间的桥墩及相关横系梁；控制倾倒方向；联网起爆拟保留梁体相邻的拟拆梁体、拟拆梁体之间的桥墩及相关横系梁；钢筋回收及爆碴清理。本申请对拟保留梁体相邻的拟拆梁体实施水压爆破，水压爆破在拟拆梁体的梁板箱室各空间产生均匀的破坏作用，避免形成大块残碴对拟保留梁体或其他构造物产生影响。本申请通过控制倾倒方向，进而避免爆破拆除对桥梁周边的生活设施造成损害或施工人员造成伤害，亦使得后期钢筋回收及爆碴清理远离居民生活区。
