Chongqing Pipeline Network Expo and Underground Space and Engineering Technology Expo 2026
Date: May 20, 2026 – May 24, 2026
Chongqing Pipeline Network Expo and Underground Space & Engineering Technology Expo will be held from May 22–24, 2026, at the Chongqing International Convention & Exhibition Center in Chongqing, China, focusing on underground pipeline networks, underground space development, engineering technologies, smart urban infrastructure, and resilient city construction. The exhibition will cover underground resource development, integrated utility corridors, surveying and mapping technologies, non-excavation technologies, pipeline maintenance, urban underground safety systems, and digital underground space planning. The event is expected to host more than 400 exhibitors and over 20,000 visitors across 20,000 sqm of exhibition space. Concurrent forums and technical seminars will address topics including urban lifeline infrastructure, BIM/CIM applications for underground space, tunnel engineering and shield tunneling technologies, smart water management, underground pipeline engineering, safety monitoring, and utility corridor operations. Organized by Shanghai Shangyaoju Exhibition Service Co., Ltd., the exhibition aims to support technical exchange, project cooperation, and industrial development within the underground infrastructure and urban resilience sectors.
