Water conservancy project diversion tunnel blocking construction method
The invention provides a water conservancy project diversion tunnel blocking construction method which comprises the following steps that a first diversion channel connected with a second diversion tunnel is formed in a first diversion tunnel, a first cofferdam is used for temporarily blocking a second water inlet, communicated with a water body, of the second diversion tunnel, and a first dry land construction area is formed; concrete is poured in the first dry land construction area, and the second water inlet is blocked; a second water diversion channel connected with the third diversion tunnel is formed in the first diversion tunnel, a second cofferdam is used for temporarily blocking a third water inlet, communicated with the water body, of the third diversion tunnel, and a second dry land construction area is formed; concrete is poured in the second dry land construction area, and the third water inlet is blocked; a third cofferdam is built between an inlet of the first water diversion channel and an inlet of the second water diversion channel, and a third dry land construction area is formed; and concrete is poured in the third dry land construction area, and the first water inlet is blocked. According to the method, plugging construction of the diversion tunnel can be achieved, the construction difficulty is low, and the cost is low.
本发明提供了一种水利工程导流洞封堵施工方法，包括以下步骤：从第一导流洞内开设一条连接第二导流洞的第一引水通道，使用第一围堰临时封堵第二导流洞与水体相连通的第二入水口，形成第一干地施工区域；在第一干地施工区域内浇筑混凝土，封堵第二入水口；从第一导流洞内开设一条连接第三导流洞的第二引水通道，使用第二围堰临时封堵第三导流洞与水体相连通的第三入水口，形成第二干地施工区域；在第二干地施工区域内浇筑混凝土，封堵第三入水口；在第一引水通道的入口和第二引水通道的入口之间建设第三围堰，形成第三干地施工区域；在第三干地施工区域内浇筑混凝土，封堵第一入水口。本发明能实现对导流洞的封堵施工，施工难度低、成本低。
