Reef Explosion Scheme for Shiplock Regulation in Dahua Hydroplant,Guangxi and Its Implementation

文章结合广西大化水电站船闸下游河道整治工程实例,介绍利用磁振动测试仪及飞石距离的控制两项指标,设计了微差控制爆破,减小了爆破对周围建筑物的影响,为同类工程施工提供借鉴。

Based on the waterway regulation practice in the downstream of Shiplock in Dahua Hydroplant,Guangxi,the Paper illustrates how to measure the earthquake wave vibrating rate by means of magnetic test instrument and how to control the distance of popping rock,so as to determine the final blasting parameters and the reef explosion scheme.It also proposes to adopt control blasting method and strengthen the cover measure to minimize the impact of blasting on the surrounding buildings.
