| Abstract: | The working environment of the pipeline in No. 3 Air Shaft of the first power cable tunnel in project of Shanghai Expo is very complicated, and the construction field is also narrow. Meanwhile some things cannot be moved,for instance, there is a 5-layer building near the west of the foundation pit containing 8 informatio ncables and 24 pores in 3-layer local telephone cables. All of these bring great difficulties and risks to enclose the structure and excavate the foundation pit. Therefore, only by optimizing the construction planning and adopting appropriate emergency measures in the construction process, the pipeline construction project can be completed smoothly. |
