Blocking gate mechanism for gravity dam diversion bottom hole and construction method
The invention belongs to the technical field of water conservancy and hydropower engineering construction, and particularly relates to a blocking gate mechanism for a gravity dam diversion bottom hole and a construction method. The blocking gate mechanism is organically composed of a gravity dam flow guide bottom hole, a supporting bottom plate, a plane door plate, an upper support and a lower support. The construction of the blocking gate is completed through nine steps of supporting bottom plate foundation construction, supporting bottom plate construction, slide way installation, plane door plate construction, upper support construction, lower support construction, waterproof structure construction, blocking gate closing construction and cover weight construction. A lock chamber does not need to be specially arranged, a steel gate does not need to be arranged either, and investment is greatly saved; a hoist and a power source do not need to be arranged, and the gate is closed through the self weight of the structure; the closing speed of the gate is adjusted by arranging the soft support, and the safety of the structure is effectively protected.
本发明属于水利水电工程建设技术领域，具体涉及一种用于重力坝导流底孔的封堵闸门机构及施工方法。本发明的封堵闸门机构由重力坝导流底孔、支撑底板、平面门板、上部支撑和下部支撑有机构成。本发明通过支撑底板基础施工、支撑底板施工、安装滑道、平面门板施工、上部支撑的施工、下部支撑施工、防水结构施工、封堵闸门关闭施工和盖重施工九个步骤，完成了封堵闸门的施工。本发明不需要专门设置闸室，也不需要设置钢闸门，大大节约了投资；本发明不需要设置启闭机和电源，通过结构自重实现闸门闭合；本发明通过设置软支撑调节闸门闭合速度，有效保护了结构的安全。
