Diversion tunnel, flood discharge and emptying tunnel and vertical shaft type spillway combined structure and construction method
The invention provides a diversion tunnel, flood discharge and emptying hole and vertical shaft type spillway combination structure which comprises a diversion tunnel arranged in a reservoir in advance, the flood discharge and emptying hole is formed in a first tunnel body section, located on the upstream, in the whole tunnel section of the diversion tunnel, and the vertical shaft type spillway is arranged on a second tunnel body section, located on the downstream, in the whole tunnel section of the diversion tunnel. A gate shaft platform is arranged on the reservoir top, a spillway inlet section of the vertical shaft type spillway is communicated with the gate shaft platform, and flood discharge is conducted through a second tunnel body section; a blocking section is arranged between the first tunnel body section and the second tunnel body section, an emergency gate well section is arranged on the upstream portion of the blocking section of the flood discharge and emptying tunnel, and a flood discharge pipeline is arranged on the portion, between the emergency gate well section and the blocking section, of the first tunnel body section. According to the method, the flood discharge cavity and the vertical shaft type spillway are arranged on the basis of the diversion tunnel in a combined mode, so that although the tunnel lines of the flood discharge cavity and the vertical shaft type spillway coincide, the required tunnel section spaces of the flood discharge cavity and the vertical shaft type spillway are relatively independent.
本发明提供了导流洞、泄洪放空洞和竖井式溢洪道结合结构，包括预先设置在库内的导流洞，在所述导流洞整体洞段中位于上游的第一洞身段上设置泄洪放空洞，在导流洞整体洞段中位于下游的第二洞身段上设置竖井式溢洪道，库顶设置闸门井平台，所述竖井式溢洪道的溢洪道进口段与闸门井平台连通，其通过第二洞身段泄洪；所述第一洞身段与第二洞身段之间设置封堵段，所述泄洪放空洞在封堵段上游设置事故闸门井段，在所述事故闸门井段与封堵段之间的第一洞身段部分设置泄洪管道。本发明通过在导流洞的基础上结合布置泄洪放空洞和竖井式溢洪道，因此泄洪放空洞与竖井式溢洪道虽然洞线重合，但各自需要的洞段空间上相对独立。
