in Minhang District, along the river, from the boundary of Minhang District in Pudong to S32 Highway, an "underground lifeline"-Puye Road Underground Comprehensive Pipe Gallery Project is being born.
Minhang District Information Office introduced that the first phase of Puye Road in Minhang District, along the river, from the boundary of Minhang District in Pudong to S32 Highway, an "underground lifeline"-Puye Road Underground Comprehensive Pipe Gallery Project is being born.
Minhang District Puye Road Phase I (Pudong Minhang District Boundary-S32 Highway) New Project, with a total length of about 7.62 kilometers, is the main road along the river in Minhang, an important part of Fengpu Express Line BRT Phase II, and one of the five "trunk pipe galleries" in the city. After the completion of the project, it will have the functions of both the main traffic road and the main underground pipeline road, and the surrounding citizens can directly reach the central areas of Pudong and Fengxian through this road.
At present, the enclosure structure of the pipe gallery foundation pit has been completed for about 4 kilometers, the main structure of the pipe gallery has been completed for about 2.0 kilometers, 80% of the substructure of the new Zhouputang Bridge has been completed, and the construction of the working well and receiving well of the Yaojiabang Bridge pipe gallery has been completed. This year, all underground comprehensive pipe galleries, rainwater and sewage pipelines and bridge revetments will be completed. All road works, traffic ancillary and greening works will be completed in 2024 to ensure the smooth completion and delivery in 2025. Looking down
from a high altitude, there is a long "hole" on Puye Road. Along the sinking escalator, it reaches the tunnel space of 9 meters underground to see the "true appearance" of this comprehensive underground pipe gallery: 7 meters wide, enough for two cars to walk side by side. The completed square pipe gallery leads to the distance. It can be seen that the steel structure is lined up, which is the enclosure structure of the foundation pit, and about 4 kilometers have been completed.
As a "commercial house" specially built for municipal pipelines, each cabin has its corresponding "household", such as the high-voltage cabin is used to place high-voltage power pipelines, and the integrated cabin is used for the installation of information pipelines and fire pipelines. Different from the traditional single-layer multi-cabin structure, the comprehensive pipe gallery of Puye Road Project is a double-layer four-cabin structure layout, the upper layer is the ultra-high voltage power pipeline and information fire pipeline, and the lower layer is the high and low voltage power pipeline. The construction
of double-deck four-cabin has high control precision and great difficulty, which is the key to the treatment of structural joints, the construction of structural waterproofing and the construction of mass concrete. To this end, the project team customized and developed a trolley formwork system suitable for the synchronous construction of the upper and lower four cabins for the pipe gallery project. The modular design should be applied to the use scenarios of different lengths and sections, combined with the simulation scheme, to optimize the construction details.

In the application of formwork, the project team compared the traditional steel formwork and wood formwork with light weight, good shape, fast assembly and recyclable high polymer formwork, which not only has low carbon and environmental protection, but also saves the input of materials and labor, and can be constructed in the open rainy season, greatly improving the construction efficiency. The actual scene map
project of
the template is large and there are many difficulties. Why should it be done?
Underground comprehensive pipe gallery, also known as the underground "dragon", delivers water, electricity, gas and other resources to the city where people can't see, and its importance is self-evident. Build a public tunnel space underground
in the city, collect all kinds of engineering pipelines such as power, communication, water supply and drainage along 7 kilometers, set up special maintenance ports, hoisting ports and monitoring systems, and implement unified planning, design, construction and management, so as to solve the problems of repeated excavation of pavement, dense overhead line network and frequent pipeline accidents. It is an important means to crack the "road zipper" and "cobweb stringing" in the city, which is the role of the underground comprehensive pipeline corridor.
In short, it is the "lifeline" of the important infrastructure that guarantees the operation of the city.
Through the integrated layout, the newly built Puye Road project not only uses land intensively, but also makes the ground space more beautiful and more integrated with the environmental landscape. According to the plan, after completion, it is difficult to find an energy pipe gallery hidden underground from Puye Road, and the escape entrance and wind pavilion of the pipe gallery are hidden in the green belt. The first phase project
of Puye Road includes underground comprehensive pipe gallery, rainwater and sewage pipeline, bridge revetment, road engineering, traffic ancillary and greening engineering, etc. At the same time, 2 new channel bridges and 16 medium and small bridges will be built.
At present, the enclosure structure of the pipe gallery foundation pit has been completed for about 4 kilometers, the main structure of the pipe gallery has been completed for about 2.0 kilometers, 80% of the substructure of the new Zhouputang Bridge has been completed, and the construction of the working well and receiving well of the Yaojiabang Bridge pipe gallery has been completed. This year, all underground comprehensive pipe galleries, rainwater and sewage pipelines and bridge revetments will be completed. All road works, traffic ancillary and greening works will be completed in 2024 to ensure the smooth completion and delivery in 2025. After the completion of the
project, there will be another road for the surrounding citizens to travel to and from Pudong and Fengxian central areas. At the same time, the project will further cooperate with the construction of country parks, promote the riverside development of Pujiang Town and Pujin Street, and contribute to the first-class riverside belt of Pujiang River.
