Method for arranging diversion buildings of canyon river hydro-junction
The invention discloses a canyon river hydro-junction diversion building arrangement method, and relates to the field of water conservancy and hydropower engineering. The invention provides a canyon river hydro-junction diversion building arrangement method which is low in cost and comprises the following steps that A, a first cofferdam is built in a river, and a diversion building with a diversion open channel is built in a waterless area jointly defined by the first cofferdam and a stable mountain; b, the first cofferdam is dismantled; c, a second cofferdam is built in the river channel, and a first dam body connected with the diversion building into a whole is built in a water-free area jointly defined by the mountain, the diversion building and the second cofferdam; d, the second cofferdam is dismantled; e, a third cofferdam is built in the river channel, a waterless area is formed around the diversion building through the third cofferdam, and the diversion open channel is rebuilt into a permanent hub building; and F, the third cofferdam is dismantled. The diversion building becomes a part of the hydro-junction after the construction of the hydro-junction is completed, so that the project investment can be reduced, and the construction period can be shortened.
本发明公开了一种峡谷河道水利枢纽导流建筑物布置方法，涉及水利水电工程领域。本发明提供一种成本较低的峡谷河道水利枢纽导流建筑物布置方法，包括如下步骤：A、在河道内修建第一围堰，在第一围堰和稳定山体共同围成的无水区域内修建具有导流明渠的导流建筑物；B、拆除第一围堰；C、在河道内修建第二围堰，在山体、导流建筑物和第二围堰共同围成的无水区域内修建与导流建筑物连成一体的第一坝体；D、拆除第二围堰；E、在河道内修建第三围堰，第三围堰使得导流建筑物周围形成无水区域，将导流明渠改建成永久枢纽建筑物；F、拆除第三围堰。导流建筑物在水利枢纽施工完成后成为水利枢纽的一部分，既可降低工程投资，又可节约施工工期。
