| Abstract: | The main span of Chongqing light rail Jialing River extra large bridge is a three-span (90m 160m 90m) prestressed concrete steel frame,nearly adjoining the Yu-Ao Bridge. On the cast-in-place support segment in Nan'an district and side span healing segment runs the line 2 light rail,the blow-off pipe is located on the Jialing River bed. The cast-in-place segment has large self-weight,support for construction is 50m in height,and the support construction is extremely difficult. This article introduces mainly the design and main construction characteristic of the cast-in-place segment support in Nan'an. |
