Supporting structure for unfavorable geological tunnel section of long-distance water delivery tunnel

The invention relates to the technical field of tunnel supporting. In particular to an unfavorable geological tunnel section supporting structure of a long-distance water delivery tunnel. The supporting device comprises a supporting device and a plurality of supporting plates arranged on the two sides of the supporting device, the supporting device comprises two supporting mechanisms, each supporting mechanism comprises a base, a supporting plate is arranged at the top of each base, a driving structure is arranged between each supporting plate and the corresponding base and used for driving the corresponding supporting plate to move, and when the driving structures drive the supporting plates to move upwards, the supporting plates move upwards. One end of each supporting plate is warped upwards, and a sealing mechanism is arranged between the two supporting plates. The supporting plates gradually move upwards through the driving structures, and in the moving process of the supporting plates, the ends, away fr
