The invention provides a construction hoist for underground engineering. The construction hoist for underground engineering comprises a supporting frame and a lifting box unit. The supporting frame is of a cylinder structure, a guide rail is arranged on the supporting frame, and the guide rail is parallel to the axis of a cylinder. The horizontal cross section of the lifting box unit is in a shape of a section ring, the lifting box unit comprises a top plate, a base plate, a first side plate, a second side plate, a large arc-shaped side plate and a small arc-shaped side plate, the first side plate and the second side plate are rectangular, a pulley is arranged on the small arc-shaped side plate, driven by a motor and installed on a track, a connecting plate is arranged on the base plate of the lifting box unit and is hinged to the base plate under a single door on the second side plate. The connecting plate is smaller than the second side plate in width, and the length of the connecting plate is larger than the distance between two lifting boxes. The construction hoist can independently ascend and descend, can be connected together for joint operation and is simple in structure, convenient to use, and a large amount of working time is saved.
