The invention relates to a corrugated pipe assembly. The corrugated pipe assembly comprises a corrugated pipe; and a displacement sensor for measuring an axial length of a corrugated pipe is arranged on the corrugated pipe. The displacement sensor is connected with an intelligent digital display apparatus for displaying the axial length of the corrugated pipe in a digital mode. The displacement sensor measures the axial length of the corrugated pipe in real time and the axial length is displayed by the intelligent digital display apparatus. Therefore, problems that the working efficiency is low and a reading number error is caused because the existing bus corrugated pipe needs manual reading of the scale can be solved.
