摘要
结合西气东输工程聊城至泰安天然气输气管道沟开挖工程的特点,探讨了沟槽石方爆破的设计原则和爆破施工方案。通过选择合适的炮孔布置方式及参数、分段装药结构和起爆顺序,提出了沟槽微差爆破技术以及减小爆破震动和飞石的安全措施,保证了通讯光缆和周围设施的安全,取得了良好的爆破效果,为工程的顺利进行创造了有利条件。
According to the characteristic of Liaocheng-Tai'an natural gas duct excavation engineering of West-East natural gas transmission project,the suitable pattern of hole disposal,the blasting parameters,the structure of stage charge,the reasonable firing method and the detonation sequence of the blasting excavation are discussed.The principle of ditching blasting and the scheme of blasting construction are summarized based on the above analysis.The techniques of millisecond blasting and safety measures of reducing vibration and controlling blasting flying rock are put forward.So the security of communications cables and the surrounding facilities are guaranteed;and ideal achievement is obtained.Favorable conditions are created for the smooth progress of West-East natural gas transmission project.
