In order to prevent concrete cracks caused by uneven settlement of the foundation, a fracture joint is set at a position every 4 - 6 m. When laying fine aggregate fiber concrete within 120° of the inner wall of the existing corrugated steel pipe, the traditional method is to fix two positioning lines between the two ends of the inner wall of the corrugated steel pipe, and a 50-mm-thick wooden square is arranged between the positioning line and the inner wall of the corrugated steel pipe.
