Dig-Hole Pile Excavation by Blasting in Cities and Towns

Abstract:

In order to avoid dig-hole pile excavation blasting effect the building structure safety and the life of residents around the project, take several controlled blasting technique measures in construction. Through taking reasonable arrangement of holes, delay time, specific charge, initiation ways and safety protection measures, and blasting vibration was measured and analized to guide blasting operations, finally the purpose of excavation blasting was achieved safely. The results show that several controlled blasting techniques used in the project are effective measures, not only ensure the good blasting effect but also control the influence of blasting vibration to surroundings, and provide valuable references to similar projects.
