The invention discloses a full-automatic construction machine of a carbon fiber cloth reinforced high-pile wharf beam-type element. The full-automatic construction machine comprises an external fixing and supporting module and an internal walking and constructing module. The external fixing and supporting module is used for fixing a device to the beam-type element and providing supporting for the internal walking and constructing module and comprises hydraulic rod fixing devices, a supporting bottom plate and external fixing and supporting module box walls; two opposite sides of the supporting bottom plate are each provided with the corresponding external fixing and supporting module box wall; and the tops of the external fixing and supporting module box walls facing to each other are each provided with the corresponding hydraulic rod fixing device. The full-automatic construction machine can achieve automatic construction in the whole process, control is not needed, and construction is stable, convenient and fast. The problem that when the high-pile wharf beam-type element is subjected to manual reinforcement restoration, work is difficult and dangerous is solved, and reinforcement performed on the high-pile wharf beam-type element through carbon fiber cloth can be conveniently and effectively implemented.
