| Abstract: | The construction of super deep working well is needed pumping confined water in the construction of power cable tunnel. Combined with the pumping confined water of the No. 6 working well in Beijing West Road to Huaxia West Road Power Cable Tunnel Project, the design demand for decompression-precipitation, construction technology and the critical control are presented and the effect of decompression-precipitation is also analyzed, which provide a reference for the construction of the super deep cable tunnel working well and the substation. |
