Shallow-hole blasting air bag damping structure for bridge pile group foundation and construction method
The invention discloses a shallow-hole blasting air bag damping structure for a bridge pile group foundation and a construction method. The shallow-hole blasting air bag damping structure is characterized by comprising blast holes (1), wherein explosives (3) are arranged in the blast holes (1); and the two ends of the explosives (3) are provided with air bags (2). For blasting effect, the shallow-hole blasting air bag damping structure is good in blasting effect and is small in influence on work efficiency under damping measures. Air bag measures can realize an expected damping target very well, and cost analysis is combined in practical engineering; and the air bag measures only increase the cost by 15.6 yuan, and therefore, the air bags become the best choice for pile group foundation construction blasting and damping.
本发明公开了一种桥梁群桩基础浅眼爆破空气袋减振结构及施工方法，其特征在于，包括炮眼(1)，在炮眼(1)内设有炸药(3)，炸药(3)两端设置空气袋(2)。就爆破效果而言，在本发明减振措施下，爆破效果良好，对工效影响很小。空气袋措施可很好的实现预期减振目标，在实际工程中，结合成本分析，采用空气袋措施仅增加15.6元，因此，空气袋成为群桩施工爆破减震的最优选择。
