Taking the working lot of No. 8 inclined shaft of Taihangshan tunnel as case history, the author presents the design and manufacture of the invert trestles and the techniques and key points of the construction of the tunnel invert by means of invert trestles. For the sake of the application of the invert trestles, the problem in the integral invert casting and the interference between the invert construction and the transportation logistics for the excavation faces are successfully resolved. The paper can provide reference for the construction of similar inverts in the future.
