Introduction This paper discusses the crossing scheme of cross-gate waterway. Due to the restriction of site and backfilling stone on the side of Hengqin, the only way to cross the Crossgate waterway is towing pipe.
Method In this paper, the key control indicators such as pullback force and radial stability of pipe were fully compared and the finite element method was used to check the radial stability of pipe.
Result The results show that MPP pipe is recommended to meet the safety requirements and facilitate construction.
Conclusion We demonstrate the feasibility of the calculation method, and this work provides some guidance for the practical application.
