Novel desilting hole structure arrangement
The invention relates to desilting tunnel structure arrangement, and belongs to the technical field of water conservancy and hydropower engineering. The system comprises a diversion tunnel and desilting tunnel combined water inlet, a desilting vertical shaft and a diversion tunnel, a desilting tunnel inlet and the desilting vertical shaft are arranged below the diversion tunnel water inlet, the downstream end of the desilting tunnel inlet is communicated with the upper end of the desilting vertical shaft, and the lower end of the desilting vertical shaft is communicated with the diversion tunnel. And a permanent plug is arranged on the upstream side of a connecting fork of the diversion tunnel and the lower end of the desilting vertical shaft to form a diversion tunnel plugging section. The desilting capacity can be enhanced, the silt condition of the water inlet of the diversion tunnel is improved, the flexibility of water inlet arrangement and tunnel arrangement is improved, meanwhile, the project amount is effectively saved, the project cost is reduced, and the later operation management difficulty is reduced.
本发明涉及一种排沙洞结构布置，属于水利水电工程技术领域。本发明包括引水隧洞和排沙洞联合进水口、排沙竖井和导流洞，引水隧洞进水口下方设置有排沙洞进口和排沙竖井，排沙洞进口的下游端和排沙竖井的上端相连通，排沙竖井的下端和导流洞相连通，导流洞在其与排沙竖井下端连接岔口的上游侧设置有永久堵头以形成导流洞封堵段。本发明能增强排沙能力，改善引水隧洞进水口淤沙情况，增加进水口布置和隧洞布置的灵活性，同时有效地节省工程量，降低工程造价，减少后期运行管理难度。
