Simple water retaining gate for diversion tunnel opening and construction method
The invention discloses a simple water retaining gate for a diversion tunnel opening and a construction method, and belongs to the technical field of water conservancy and hydropower. Comprising a tunnel face poured on the outer side of the diversion tunnel, a gate groove structural section and a gate. A gate groove matched with a gate is formed in the gate groove structure section. In a dry season, the gate is hung above the gate groove structural section; during blocking construction, the gate is hung into the gate groove to stop water; the sealing rock ballast is arranged outside the gate; the backfill rock ballast is arranged on the inner side of the gate; and the water retaining cofferdam is built at the tail end of the lining. According to the invention, the original design standard lock chamber structure is canceled, the excavation of the side slope of the hole is reduced, and the concrete lining work amount of the inlet section and the lock chamber pouring work amount are reduced; installation, operation and disassembly of the hoist and prefabrication, hoisting and other work of the concrete gate are avoided; under the condition that a hoist and a lock chamber structure do not exist, a simple gate groove structure is designed, a common steel formwork is properly reinforced, then water is blocked in the groove, and the aim of blocking the interior of a diversion tunnel is smoothly achieved.
本发明公开了一种导流洞洞口简易挡水闸门及施工方法，属于水利水电技术领域；包括在导流洞外侧浇筑的洞脸、门槽结构段以及闸门；所述门槽结构段内设置有适配闸门的门槽；在枯水期，所述闸门吊放在门槽结构段上方；在封堵施工时，所述闸门吊放入门槽中挡水；还包括：闸门外的封堵石渣、闸门内侧的回填石渣、在衬砌末端砌筑的挡水围堰。本发明，取消原设计标准闸室结构、减少洞口边坡开挖、减少进口段的混凝土衬砌工程量和闸室浇筑工程量；避免启闭机的安装、运行、拆除，以及混凝土闸门的预制、吊装等工作；实现在无启闭机、闸室结构的情况下，通过设计简易门槽结构，对常用钢模板适当加固后进行槽内挡水，顺利实现导流洞内封堵目标。
