| Abstract: | In the construction of comprehensive pipelines of the main trunk in Chenggong, Kunming City, the new technique of "double-way opposed-pulling steel jacket" is used to secretly cross Kunyu Expressway. In order to meet the requirement of the opposed-pulling technology for the cable hole, the method to construct the cable hole of "cable hole pipe arranged in rough hole" is studied and put forward, which is feasible after implemented. |
