On April 17, with the completion of the 69th ring pipe section of the left line of the pipe jacking section, the three-lane super-large section rectangular pipe jacking tunnel of the Phoenix Avenue Rapid Transformation Project successfully overcame the technical problems and successfully crossed the Dongguan-Foshan Expressway viaduct.
At the same time, the 10kV Jiaomen F4 Jinmao Line A line was also successfully transmitted, and the pipeline relocation and reconstruction project of the Phoenix Avenue Rapid Transformation Project (level crossing section) was successfully completed.

The pipe jacking tunnel passes under the Dongguan-Foshan high-speed viaduct
Xiaonan learned from the Nansha District Construction Center that the pipe jacking section of the Fengze Road-Huangge South Road tunnel of the Phoenix Avenue Rapid Transformation Project passes under the Huangge South Road and the Dongguan-Foshan Expressway Viaduct, with a pipe jacking section of about 151.5 meters long and a pipe jacking section of 14.8 meters * 9.426 meters, which is the largest rectangular pipe jacking section in South China.
The pipe jacking tunnel successfully passed through the Dongguan-Foshan high-speed viaduct, which filled the technical gap of the major structures under the super-large section pipe jacking in China, which not only provided valuable experience for the follow-up pipe jacking construction, but also laid a solid foundation for ensuring that the whole line penetrated the important nodes.

It took one month to successfully complete the relocation of the pipeline
The rapid reconstruction project of Fenghuang Avenue (level crossing section) involves 110 thousand volt transmission lines, 10 thousand volt distribution lines and other pipelines of Jiaomen substation, and faces a series of difficulties such as tight relocation and transformation period, complex pipelines, difficult construction and dense traffic flow.
In February 2024, the Nansha Power Supply Bureau and the Nandian Company drew up a schedule of relocation and transformation construction plans according to the commissioning nodes. At the end of February, Nandian Company officially entered the site to carry out civil construction.
On March 28, with the successful power transmission of Jiaomen F4 Jinmao Line A, the relocation and reconstruction project of Phoenix Avenue Rapid Transformation (Level Crossing Section) was successfully completed.
"The relocation and transformation project lasted for one month, and 25 relocation lines were completed, involving 31 cables, with a new cable length of about 13,892 meters, and a total of 650 staff members. The person in charge of the Huangge Power Supply Station of Nansha Power Supply Bureau said that the successful completion of the relocation and transformation project marks a breakthrough in the new stage of the rapid transformation project of Phoenix Avenue.
