Core Viewpoint - The article highlights the dedication and routine work of heat supply workers in Beijing, particularly during the Spring Festival, to ensure the warmth and safety of the city's heating network [1][3]. Group 1: Company Overview - Beijing Heat Supply Distribution Company is responsible for a heating pipeline network that spans 262 kilometers across three districts: Xicheng, Haidian, and Fengtai [3]. - The company employs a "pipeline contractor" system, where each worker is responsible for 25 to 30 inspection wells, ensuring they are familiar with the location, valve types, production years, and maintenance records of each section [11]. Group 2: Operational Details - During the Spring Festival, heat supply workers conduct daily inspections of heating pipelines in densely populated areas to ensure residents remain warm [3]. - The inspection process involves using specialized equipment such as thermal imaging cameras and electronic listening rods to detect temperature changes and potential leaks in the pipelines [9]. - The underground temperature can reach around 40 degrees Celsius, creating a significant temperature difference of up to 50 degrees Celsius compared to the surface [7]. Group 3: Technological Integration - The company has installed a "situation awareness system and track inspection robots" in the underground wells for real-time monitoring of temperature and liquid levels, which can trigger automatic alarms in case of anomalies [11]. - The combination of technology and the experience of workers allows for effective monitoring and quick response to any issues in the heating network [11].
