| Abstract: | The supporting and back structures are important temporary structures in jacking construction of bridges and culverts, and are of great importance in ensuring smooth construction and guaranteeing the time limit for a project. In this article, the author introduces the application of pre-cast reinforced concrete retaining wall and back to the jacking construction of the fourth-period special railway for the Dalate Electricity Plant, which underpasses the Baodong Highway. And the paper also shows the structure, calculation method, and key points in the construction of pre-cast reinforced concrete retaining walls and backs, thus providing certain experience for the construction of similar projects. |
