On April 21, 2023, the 26th China International Trenchless Technology Seminar and Exhibition, which lasted for three days, came to a successful conclusion. The exhibition covers an exhibition area of 20000 square meters, and the organizing committee has selected 123 companies from the industry to showcase their latest products and technologies on site. Among them, 27 companies participated in the exhibition for the first time, accounting for 21.95% of the total exhibitors. 95% of the participating companies brought dozens of physical products for exhibition, and all the bare spaces were specially decorated and all the exhibits were sold out. 3635 professional visitors from 14 countries and regions, as well as 31 provinces and autonomous regions, registered to visit the exhibition. A total of 9079 people attended the three-day conference, and 169 people registered to participate in the seminar.

The China International Symposium and Exhibition on Non Excavation Technology is presenting to everyone the vibrant vitality and development potential of China's non excavation industry with an unexpected scale and a wealth of cutting-edge technologies. With the end of the epidemic, the Chinese economy has taken the lead in global recovery. The feedback from exhibitors and visitors reflects the growing demand for non excavation technology in China's national economic development. The active participation of foreign experts and reporters demonstrates the international peers' attention to the continuous expansion of China's non excavation market. Driven by favorable domestic policies, the sustainable improvement of sewage treatment plants nationwide is being carried out in parallel with the improvement and efficiency of pipeline networks, as well as the repair of pipeline networks. Faced with the huge market of urban pipeline maintenance and repair, municipal enterprises or emerging enterprises have joined the non excavation industry, and the number of exhibiting enterprises in pipeline testing and repair has surged.
ITTC is an important platform for meeting new customers and old friends, conveying industry trend information, and sharing future technologies. We are full of confidence in the future, and the global economy is gradually recovering. In 2024, we will continue to arrange exhibition halls according to the classification of non excavation techniques, providing visitors with a better viewing experience. To achieve this goal, we will continue to work hard.
We sincerely invite relevant units and professionals from the non excavation industry to attend the conference and visit the exhibition. We look forward to discussing the development prospects and business negotiations of the non excavation industry with you in Changsha!
