| Abstract: | Owing to the fact that piers 188 and 189 of the Jiulonggang Mega Bridge are close to the existing Huainan Railway, the roadbed of the railway is intensified with Type-D make-shift beams during the construetion of the low capped pile foundation to ensure the safety of the operation of the railway and the construction;steel sheet cofferdams made up of type steels are used to intensify the low capped pile foundation to ensure both the safety of the operation of the existing railway and the safety of the construction of bridges and culverts. The project may serve as a useful reference for other similar projects. |
