Diversion tunnel upstream temporary plugging structure and method
The diversion tunnel upstream temporary plugging structure comprises a concrete structure of a diversion tunnel, a diversion pipe is installed at the bottom of the upstream end of the concrete structure in the water flow direction, the diversion pipe and the concrete structure are positioned through a water blocking limiting device, a plugging door is installed on the outer side of the shoulder of the upstream end of the concrete structure, and the upstream end of the diversion pipe extends out of the plugging door. A first blocking wall body is arranged on the downstream side of the blocking door, a second blocking wall body is arranged at the position, located at the tail end of the diversion pipe, of the downstream direction of the first blocking wall body, and concrete is poured between the first blocking wall body and the second blocking wall body. And construction conditions are provided for downstream permanent plugging.
导流洞上游临时封堵结构及方法，包括导流洞的砼结构，所述砼结构的上游端底部沿水流方向安装有导流管，导流管通过阻水限位装置与砼结构定位，砼结构上游端的肩部外侧安装有封堵门，导流管的上游端伸出封堵门，所述封堵门的下游侧设有第一封堵墙体，第一封堵墙体的下游方向在位于导流管的尾端设有第二封堵墙体，第一封堵墙体与第二封堵墙体之间浇筑有混凝土，通过该结构能够对导流洞上游进行快速的临时封堵，为下游永久性封堵提供了施工条件。
