RC STEEL COMPOSITE HOLLOW RC SUBMERGED FLOATING TUNNELS USING PRESTRESSED METHOD AND METHOD THEREOF

摘要

The present invention relates to a steel composite hollow RC underwater tunnel using a prestressing method and a construction method thereof, and more particularly, to a tunnel composite module having a tunnel module formed of a steel composite hollow reinforced concrete section, A tensioner for firstly bonding an end portion of the tunnel module to an end portion of another tunnel module in a close contact state while preventing a deflection due to a flexural deformation by providing a prestress to the joint surface; A sealing member sealing at least one of an inner periphery and an outer periphery of the joint surface; And a grout pierced along the inner circumference of the joint surface to secondary-bond the tunnel modules to improve shear resistance while reinforcing the sealing of the sealing member. According to the present invention, since the tunnel module is made of a steel composite hollow reinforced concrete section, it is excellent in strength and can be assembled and constructed. Since the tunnel modules are firstly bonded by the tent and secondly bonded by the grout, Can be bonded.
