| 摘 要： | 介绍了采用塑料导爆管接力式起爆网络的顺序微差控制爆破新技术,分两次成功地拆除了沙溪口水电站二期上游混凝土围堰工程。爆破混凝土量19800m~3,总装药量为15.84t,起爆段数分别为227段和345段。爆破完全达到了预期的效果。爆破安全监测结果也表明,爆破对邻近的水工建筑物没有产生丝毫不利影响。

| Abstract: | Demolition blasting of the concrete cofferdam at the upstream of the shaxikou hydroelectric power station is carried out in two separate times by MS delay blasting with nonel detonating network. The concrete muckpile amounted to 19800m~3, the explosive charge totalled 15.84t, and the nonel relay detonating networks consist of 227 and 345 sections connected respectively in the two times. As a result, the demolition project is fulfilled successfully and the safety monitoring showed that the buildings near the blasting site were unaffected entirely. |
