The invention discloses a pipe-roofing push bench provided with lock guiding devices and an attitude control method thereof. The push bench comprises a push bench housing and the lock guiding devices. The lock guiding devices are mounted on the tail portion of the side surface of the push bench housing. Each lock guiding device comprises a wedge-shaped protection block projecting towards the outer side of the push bench housing; the thickness of the front end of the wedge-shaped protection block is less than the thickness of the rear end of the wedge-shaped protection block; and the front end of the wedge-shaped protection block points to the head portion of the push bench housing. During a steel pipe section jacking process, the lock guiding devices block the front ends of locks on the outer side of a steel pipe section, so that a phenomenon that the locks deform as the locks touch hard materials such as rocks can be avoided, and the resistance of the steel pipe section during the jacking process can be reduced.
