Summary:The invention relates to a method for constructing an inclined shaft by applying a TBM (Tunnel Boring Machine) with an earth pressure balancing function, wherein the method comprises the following steps: (1) judging the position of a waterproof layer in the front of TBM construction before carrying out TBM tunnelling construction; (2) drilling by utilizing an advanced detecting/grouting drilling machine to carry out underground water pre-discharging construction; (3) carrying out continuous downhill tunnelling construction by utilizing an inclined shaft TBM method; (4) conveying the air volume required for TBM construction to the last ring of lining segment of TBM construction equipment; (5) carrying out inclined shaft counter-slope underground water pump drainage; (6) carrying out long-distance large-gradient material transportation and deslagging; and (7) carrying out conversion construction in two tunnelling modes including a single shield TBM opening manner and an earth pressure balanced shielding manner.
