The invention discloses a concrete construction method for an upper bending segment of a shaft. The concrete construction method comprises the following steps of calculating a construction load-bearing platform; after the construction of a straight segment of the shaft is finished, arranging the construction load-bearing platform at the boundary of the upper bending segment and the straight segment of the shaft; performing concrete lining of the upper bending segment of the shaft and backfilling construction lateral tunnels; during the construction of the upper bending segment, reserving a skylight of the upper bending segment, enabling a door frame of the skylight to extend the well wall of the construction lateral tunnel to form a courtyard to be used as a construction passage, and backfilling two sides of the courtyard to form a construction platform; and plugging the skylight and the courtyard to complete the construction of the upper bending segment. According to the concrete construction method disclosed by the invention, the problem of the construction passage is solved for the construction of the upper bending segment of the shaft, construction staff directly enter the upper bending segment from the skylight for construction, construction materials are enabled to directly enter the upper bending segment from the skylight for construction, the difficult problem caused by the situation that the construction staff enter the upper bending segment from a vent hole in a gate well for construction and the construction materials are enabled to enter the upper bending segment from the vent hole in the gate well for construction are solved, and the construction technique of the upper bending segment of the shaft is improved.
