| 中文摘要: |
| 为了确保复杂环境下砖结构烟囱爆破拆除的安全倒塌,根据待爆烟囱结构特点与周围环境,通过人工预处理措施,在爆破正梯形缺口两侧底角对称开设定向窗,在烟囱倒塌方向中心部位开设导向窗.选择合理的爆破参数、切口参数、爆破网络,通过安全校核和安全防护措施,达到了预期爆破效果,保证了周围建筑物的安全,为类似爆破工程提供了借鉴. |
| 英文摘要: |
| To ensure the blasting demolition collapse of the brick structured chimney in complex environment, based on the characteristics and environment of the chimney,the orientation windows on both sides of corner in blasting trapezoid gap and the guide window in the middle of the chimney on the collapse direction was opened up on chimney.The appropriate blasting size,notch size and blasting network was chosen,the safety check and safe protected measures were taken to achieve expected blasting effect,ensuring the safety of surrounding buildings.It can provide reference for similar projects. |
