| 摘 要： | 介绍了采用控制爆破技术拆除桥墩部分不合格钢筋混凝土的方法。在预留部分打一排导向孔,对爆破冲击波起到隔离、衰减的作用。在爆破拆除不合格的钢筋混凝土的过程中,保证了桥墩预留部分的混凝土不受破坏,此经验可为类似工程参考。

| Abstract: | This paper introduced the employment of controlled blasting to dismantle an unqualified reinforced concrete of the bridge pier.In this engineering,a raw of guiding holes was drilled in hope to isolate and attenuate the blasting shock wave.This consideration ensured the protection of the reserved section of concrete from destroy in the course of blasting demolition.The method could be consulted by engineering of the like. |
