河床式水电站尾水河道爆破拆挖工程施工介绍

Analysis on the Construction of Blasting Demolition Engineering of Tailrace River in River Channel Hydropower Station

为解决河床式水电站尾水壅堵问题,对已投产发电的贯流机组水电站尾水纵向导墙建筑物和河床岩坎进行爆破拆挖施工,应用专业的爆破技术和完善的安全防护,采用“筑岛”平台填筑施工的办法,在不影响机组发电前提下,安全完成了工程施工,取得了预期效果。

In order to solve the problem of tailrace blockage in the river channel hydropower stations, blasting demolition construction is carried out on the tailrace longitudinal guide wall buildings and the riverbed rock bar of tubular hydropower station in service. With the application of professional blasting technology and perfect safety protection, and the use of "island-building" platform construction method, the engineering construction completes safely and realizes the expected goal without affecting the power generation of units.
