Underground pipelines and comprehensive pipe corridors are important infrastructure in the city. Their safe operation is directly related to the normal operation of the city. Therefore, they are often called the "lifeline" or "aorta" of the city.

This month coincides with the national "Safety Production Month". Yesterday, the Suzhou Underground Pipeline and Road Parking Management Office and Suzhou Daily Newspaper Group launched a science popularization observation activity with the theme of "Pipeline and Pipe Gallery Work Together to Explore Safety and Protect You and Me Together" . Dozens of enthusiastic citizens and Xinlei reporters from the Suzhou Daily were invited to visit the two major science museums of Suzhou underground pipelines and comprehensive pipe corridors. During the fun interactions, they learned about the importance of standardized construction and scientific management of pipelines and pipe corridors. sex; go deep into the comprehensive pipe corridor to explore the secrets, and witness with your own eyes the current status of the construction, operation and maintenance of Suzhou underground pipelines and comprehensive pipe corridors.

"One-stop" control to avoid damage caused by improper construction

The Suzhou Underground Pipeline Science Popularization Museum is the first underground pipeline-themed science popularization museum in China. Since its opening in October 2015, it has provided tens of thousands of citizens with a close understanding of the "underground city" opportunity. In the past two years, as the construction and management of underground pipelines in Suzhou have been continuously upgraded, the knowledge content in the science museum has also been continuously updated and improved. Today, the venue brings together the latest developments in the operation of underground pipelines across the city.

venue staff said that at present, the total length of underground pipelines in the city exceeds 70,000 kilometers, which can be connected more than once around the earth. There are more than 40,000 kilometers of underground pipelines in Suzhou alone; as of May 2022, the roads in central Suzhou A total of 8,829 kilometers of underground pipelines have been discovered in streets and alleys. They mainly include 18 types such as water supply, drainage, gas, heat, electricity, communications, radio and television, etc.

The ground under urban roads is actually very fragile. Any disturbance in underground pipelines may affect the operation of the city. They are like human "nerves" and "blood vessels". If they are not managed and maintained scientifically, they will not only affect normal functions, but even cause serious harm.

"Everyone should have seen in the news that in some places, cables or water pipes under roads were cut due to improper construction, resulting in power and water outages in large residential areas." In addition, due to improper planning, violent construction and other reasons, resulting in Situations with serious consequences have also occurred in some cities. Gas pipeline explosion accidents, oil pipeline explosions resulting in deaths, severe floods and heavy losses...the real-life cases are shocking and make visitors shake their heads.

In order to ensure the safe and orderly operation of underground pipelines, Suzhou City has entered the city's dynamic pipeline information into the city's comprehensive collaborative supervision system for underground pipelines, realizing information management. By building a "one picture" of underground pipeline business management information, and management data related to each link such as planning acceptance and approval, project construction, completion, and maintenance, "one-stop" management and control is achieved. The municipal urban management department uses information management methods to minimize the impact of pipeline excavation and maintenance on residents' lives, effectively ensuring the safety and regulations of the entire process.

Alleviating "urban diseases" and giving full play to the role of smart pipe corridors

Build a public tunnel space underground in the city, integrating various pipelines and pipes into one, unified planning, unified design, unified construction and management, so as to avoid pipeline construction time Then, we can “eviscerate” the condition of the road, reduce the probability of pipeline accidents, and intensify the urban underground space—this is the role of the underground comprehensive pipe gallery.

In recent years, Suzhou City has been included in the first batch of 10 pilot cities for underground comprehensive pipe corridors in the country, and five major projects have been successfully promoted; Suzhou High-tech Zone, Wujiang District and many other comprehensive pipe corridor construction projects have Sequential advancement... In order to ensure the safe and efficient operation of the underground comprehensive pipe gallery, Suzhou has implemented real-time monitoring and early warning of the corridor body, the internal environment of the pipe gallery, and the operating status of each pipeline.

Referring to the actual construction status of Suzhou's comprehensive pipe gallery, the Municipal Underground Pipeline Management Office has built the province's first comprehensive pipe gallery science museum.The popular science museum displays a single cabin of a comprehensive pipe gallery, with pipelines and pipes of different thicknesses and functions such as sewage, low-voltage cables , high-voltage cables, radio and television, communications, etc. arranged in an orderly manner on the gallery. The interior of the corridor also contains the most cutting-edge intelligent management and control technology of comprehensive pipe corridors in China. The

venue not only demonstrated how the intelligent simulation monitoring and early warning platform operates, but also a "robot" demonstrated the "black technology" of smart inspection. "This is an intelligent inspection robot. It can complete automatic inspections of the entire cabin and around the clock, and collect, analyze, warn and process various data in the corridor." What the staff of the Pipeline Gallery Science Museum said is exactly what the pipe gallery staff said. A device that slides along the metal track at a constant speed above the corridor model. It is not "big", but it can carefully "diagnose" any abnormal conditions inside the pipe gallery with its clear "vision" and keen "smell". So that when abnormal problems such as pipeline leakage are discovered, repairs can be completed as soon as possible.

In order to have a more intuitive understanding of how to construct and manage the Suzhou integrated pipe gallery, during the event, visitors followed the pipe gallery operation and maintenance personnel to go deep into the 22-meter-underground main line demonstration section of the Chengbei Road underground comprehensive pipe gallery to see the "true appearance" ". In the pipe gallery that is nearly 10 meters wide and 5 meters high, 8 types of pipelines, including electricity, communications, water supply, sewage, cable TV, natural gas, heat, and reserved gray water, are arranged in four cabins according to different functions. settle down". Among them, the largest water tank is still very "spacious" after accommodating pipelines, and can provide maintenance and operation space for small maintenance vehicles; due to the use of a large number of explosion-proof materials and explosion-proof facilities, the gas tank has the highest cost, but the smallest size, 1.8 People taller than 1 meter can only enter by bending down. The monitoring and early warning devices inside the

pipe gallery play multiple roles such as intrusion prevention, environmental monitoring, and emergency dispatch. According to the operation and maintenance personnel, the monitoring and early warning function in the pipe gallery currently covers the entire corridor section; drone inspections and other methods are used to detect problems outside the pipe gallery. These data information will be transmitted in real time to the "intelligent heart" of the comprehensive pipe gallery monitoring center. Full-time maintenance personnel pay close attention to the operation status of the corridor and "life pipeline" 24 hours a day. Seeing how the smart management platform achieves precise control through the skilled operation of operation and maintenance personnel, visitors expressed their eye-opening.

The relevant person in charge of the Municipal Underground Pipeline and Road Parking Management Office said that the "smart pipe gallery" is a microcosm of the smart city underground. Creating smart pipe corridors that are functional, stable, reliable, technologically advanced and “think for themselves” can help alleviate “big city disease” and achieve refined and dynamic management.

allows more people to join the team that cares about and protects the city's "main artery"

The day's activities, through visible, tangible and tangible ways, allowed the public to enhance their awareness of disaster prevention and reduction, and experience the importance of protecting the city's "main artery" "The importance of safe operation.

Since his work is closely related to production safety, Mr. Chen, a citizen, immediately signed up to participate after seeing the event notice. During the participation in the event, Mr. Chen interacted closely with the staff and said that he benefited a lot from this event and that some management concepts and management methods can be used for reference in future work. This event also allowed citizen Ms. Mu to see the rigor and difficulty of standardized construction and scientific management of pipelines and pipe corridors. "I knew nothing about them before, but now I am proud that Suzhou has such an advanced level of management."

Xinlei young reporters from the Suzhou Daily who signed up to participate in the event also said that such an immersive science popularization activity, It gave them a deeper understanding of the mysterious "underground city" and the importance of scientific planning, standardized construction, and safety management. After returning home, they will also pass on this knowledge and safety concepts to their family, friends, and teachers, and through "little hands holding big hands", more people will participate in the team that cares for and protects the "main artery" of the city.
