复杂环境下水塔的爆破拆除

Demolition Blasting of a Water Tower in Complicated Environment

介绍复杂环境下的水塔定向拆除爆破实例及其保证定向倒塌、控制爆破飞石和水塔顶部箱体的水压爆破破碎设计。水塔准确地沿南偏东60°方向倒塌,水罐按设计龟裂,未产生爆破飞石。爆堆全部塌散在砂土缓冲层上,水塔落地时的碎石飞溅得到有效控制,个别飞散物未对周围造成任何损坏。地下管道完好无损,罐体水比较顺利排离广场,爆破达到了预期效果。

The demolition blasting process of a water tower in complicated environment, and the measures that ensure directional collapse, control blasting fly rock and the design of blasting fragmentation about water tower＇s top are introduced. The water tower collapses towards the south with an angle of 60° to the east and the top box cracks follow the design without any flying rocks. All of the fallen rocks are accumulated on the sand buffer layer, the flying debris are well controlled, there is no any damage to the surrounding buildings. The underground conduits are not influenced by the blasting process, the water in the top box is sent out quickly from the square. This demolition blasting project makes a wonderful effect.
