Zusammenfassung:	The utility model provides a simple mistake-proofing tool for on-site installation of a guide pipe, which relates to the technical field of axial extrusion pipeline connecting tools and comprises a combined guide pipe and a marking tool sleeved on the combined guide pipe. Two hole grooves are formed in the marking tool, groove holes are formed in the positions adjacent to the hole grooves, and a through hole structure is arranged at the top of the marking tool. The combined guide pipe comprises a first connecting piece, one end of the first connecting piece is connected with a first guide pipe, the other end of the first guide pipe is connected with a second connecting piece, the other end of the second connecting piece is connected with a second guide pipe, and the other end of the second guide pipe is connected with a third connecting piece. According to the marking tool, the two cross-shaped kidney-shaped hole grooves are formed in the marking tool, and the insertion depth of the guide pipe in the connecto
