When the axis of the powerhouse needs to move upstream, according to the position adjustment information of the axis of the powerhouse, that is, the length of the axis of the powerhouse moving upstream, the length of each flat section of the pipeline of the water transmission line is correspondingly reduced, that is, the length of the upper flat section Lpy1, the length of the middle flat section Lpy2, and the length of the lower flat section Lpy3 are adjusted, and the length of the tailwater tunnel Lw is correspondingly increased, and Lw=Lpy1+Lpy2+Lpy3 is satisfied at the same time; in actual application, if the pressure pipeline is in the form of a single vertical shaft or a single inclined shaft, there are only the upper flat section Lpy1 and the lower flat section Lpy3, and there is no middle flat section Lpy2, and Lw=Lpy1+Lpy3 needs to be satisfied accordingly;

[0117] Furthermore, reducing the length of the tailwater tunnel specifically includes:

[0118] When the powerhouse axis needs to be moved downstream, the length of the tailwater tunnel is shortened according to the powerhouse axis position adjustment information, and the lengths of the respective flat sections of the pipeline of the corresponding water transmission line are adjusted, and the sum of the lengths of the respective flat sections is made equal to the length of the tailwater tunnel;

[0119] like Figure 6 As shown, when the plant axis needs to move downstream, the length of the tailwater tunnel Lw is correspondingly reduced according to the plant axis position adjustment information, that is, the length of the plant axis moved downstream, and the length of the upper flat section Lpy1, the length of the middle flat section Lpy2, and the length of the lower flat section Lpy3 are increased, and Lw=Lpy1+Lpy2+Lpy3 is satisfied at the same time; similarly, in actual application, if the pressure pipeline is in the form of a single vertical shaft or a single inclined shaft, there are only an upper flat section Lpy1 and a lower flat section Lpy3, and there is no middle flat section Lpy2, and Lw=Lpy1+Lpy3 needs to be satisfied accordingly.

[0120] It should be noted that the horizontal length mentioned above is not the actual length. The actual length needs to be calculated based on the horizontal length, each flat section and the slope of the tailwater tunnel.
