摘要
为确保围堰附近尾水洞衬砌混凝土、尾水出口引渠、尾水闸室等永久性建筑物及检测设备的安全,使导流洞出口档水围堰(重力式水下混凝土结构)爆破拆除任务能安全、优质、高效地完成,针对复杂的围堰挡水体结构,采用堰内充水爆破法拆除围堰。以高程EL2603.5 m为分界线,分上下两部分介绍了爆破设计方案,包括爆破参数选取和爆破网路设计,并重点论述了围堰混凝土结构爆破拆除过程中的施工方法和控制措施。
In order to guarantee the permanent construction and test equipment＇s security, such as the tailrace tunnel lining concrete, the approach channel for the export of tail water and the tailrace gate chamber, the explosive demolition of diversion tunnel outlet water＇s cofferdam （ gravity type underwater concrete structure ） can be finished safely, quality, efficiently. The blasting with water in the cofferdam was applied for the complex water-retaining structure. Taking EL2603.5 cm as the dividing line, the design of blasting scheme was introduced in two parts including the selection of blasting parameters and the design of blasting network. The construction method and control measures of blasting demolition of cofferdam of concrete structure was mainly discussed.
