Research on large-diameter and long-distance steel pipe launching through airbag slideway
For a large-diameter and long-distance cross-river sunken pipe project,the traditional steel pipe launch-ing method has problems such as more steel pipe sections,much underwater connecting work,and the impact of long-term occupation of water area on navigation.Therefore,referring to the launching method of ship airbag,a large-diameter and long-distance steel pipe launching method through airbag slideway is proposed.ABAQUS soft-ware was used to simulate and analyze the stress changes during the launching process of steel pipes by airbag slide-way method for Jingu River sunken pipe project,based on which the launching plan was determined and implement-ed,so as to explore a feasible and brand new steel pipe launching method,effectively reduce the construction diffi-culty of large-diameter and long-distance steel pipe launching.
