Power generation tailrace tunnel and diversion tunnel combined arrangement method
The invention provides a power generation tailrace tunnel and diversion tunnel combined arrangement method, which relates to the technical field of hydropower and hydraulic engineering, and comprises the following steps of: for hydropower engineering with a power generation tailrace tunnel and a diversion tunnel on the same side of a river channel, judging the feasibility of combination of the power generation tailrace tunnel and the diversion tunnel; when the combined section of the power generation tailrace tunnel and the diversion tunnel can always keep a single water flow state with pressure flow or without pressure flow in the operation period of the hydropower station, and the respective functions and safety requirements of the power generation tailrace tunnel and the diversion tunnel can be ensured, the power generation tailrace tunnel and the diversion tunnel can be directly combined; otherwise, a ventilation hole needs to be formed in the combined section of the power generation tailrace tunnel and the diversion tunnel. According to the method, the existing low-elevation diversion tunnel is utilized, and the functions and safety requirements of the power generation tailrace tunnel and the diversion tunnel are ensured through reasonable line arrangement, related calculation and safety guarantee measures, so that the engineering investment is saved, and the safety, reliability and technical advancement of the technical scheme are ensured.
本发明提供了一种发电尾水洞与导流洞结合的布置方法，涉及水电水利工程技术领域，包括如下步骤：对于发电尾水洞与导流洞在河道同侧的水电工程，判断发电尾水洞与导流洞结合的可行性，当发电尾水洞与导流洞结合段在水电站运行期能始终保持有压流或无压流的单一水流流态，且能保证发电尾水洞和导流洞各自功能和安全要求，便直接将发电尾水洞和导流洞结合；否则，发电尾水洞与导流洞结合段上需要设置通气洞。发明利用已有的低高程导流洞，通过合理的线路布置、相关计算和安全保障措施，确保发电尾水洞和导流洞的功能及安全要求，既节省了工程投资，又保证了技术方案的安全可靠性和技术先进性。
