| Abstract: | Taking an urban elevated railway-crossing interchange project as an example,the existing elevated cantilever plates are required to cut.In order to guarantee the construction safety of overpassing the railway line under the complicated conditions and decrease the influence on the existing roads,the scheme to setting the cutting protection platform is adopted.The installation,fabrication and removal technologies of the protection platform are introduced in detail.The engineering practice shows that this structure is safe and reliable,and can be referred for the construction of the similar bridges. |
