The invention discloses a pull-rod-less culvert trolley construction device, which comprises a trolley truss composed of connected rod members. A plurality of jacks are connected to the left and righttruss bodies of the trolley truss and are connected with vertically arranged inner beams. The inner beams on the same side are connected to an inner formwork. An outer formwork is disposed on an opposite side of each inner formwork and faces the inner formwork. The back of each outer formwork is connected to multiple outer beams. The top of two outer beams located on both sides of the trolley truss and in the same cross section are connected through a pull rod. The outer side of the bottom of each outer beam is provided with one assembly block. The outer side of the assembly block is attachedto a steel plate stop block. The assembly block and the steel plate stop block extend into pre-embedded twisted steel bars in a culvert foundation. A lock nut is screwed into the pre-embedded twistedsteel bar outside the steel plate stop block. In the process of connecting the inner and outer formworks, the construction device does not need to pre-embed a PVC pipe or use a pull rod, so that a final culvert wall is not provided with holes, thereby achieving good integrity and avoiding water leakage.
