Coincidentally, before this, the quality problems of the external power pipeline supporting project of Qingdao Metro 1 Line were exposed by the construction party. On June 29th and 30th, Qingdao Metro Group Co., Ltd. released the investigation results one after another, claiming that China Gezhouba Group Electric Power Co., Ltd., the general contractor of this project, was suspected of illegal subcontracting, and was included in the blacklist of Qingdao Metro project construction, with a penalty of 6,543,800 yuan deducted from Gezhouba Electric Power.
According to the interface news report, an insider who asked not to be named said that the project previously exposed by the construction party only involved the backfilling of underground power pipelines, which was equivalent to pulling a line from the State Grid to connect with the substation of the subway line. Therefore, this line is different from the subway operation line, and the backfilling project of power exhaust pipe has cut corners, which is not directly related to the collapse accident of subway station.
According to public information, Qingdao Metro 1 Line is a cross-sea subway line with a total length of 60. 1 1 km. It starts at Emei Mountain Road Station, connecting five municipal districts, namely Huangdao District, Shinan District, Shibei District, Licang District and Chengyang District, and ends at East Guo Zhuang Station. It is expected to open by the end of 2020.
