控制爆破在泉港分洪闸基础开挖中的应用

Application of controlled blasting in the foundation excavation of Quangang Flood Diversion Sluice Project

泉港分洪闸改建过程中,在进行新闸基础开挖时,必须保证紧邻的老闸不受破坏,以承担当年的度汛任务。为了有效地保证保留建筑物的安全稳定,减少对爆区周边环境的影响,采用了控制爆破,并为此进行了爆破试验,保证了工程爆破开挖取得成功。

In the excavation of the foundation of the new sluice gate of the Quangang Flood Diversion Sluice Project, it should ensure that the neighboring old sluice gate to be undamaged so that it can undertake the flood prevention task in that year. In order to effectively ensure the safety and stability of remaining buildings and to reduce the impact on the surrounding environment of blasting area, the controlled blasting was adopted and the blasting tests were made to ensure the success of the blasting and excavation of the project.
