Under the guidance of CSTT, ISTT, ASCE and Cuire, China Engineering Construction Standardization Association, pipeline inspection and repair Committee of China Municipal Engineering Association and Zhengzhou University The 25th China International Trenchless Technology Symposium and Exhibition (ITTC 2021) supported by China University of Geosciences (Beijing), China University of Geosciences (Wuhan), Chengdu University of technology, School of civil engineering, Tongji University and School of construction engineering, Jilin University will be held in Suzhou International Expo Center from April 16 to 18.


The period from 2018 to 2019 is the stage of rapid development of trenchless technology industry in China. With the extensive application of Trenchless Technology in municipal, gas, communication, oil and other industries, trenchless technology has also made great progress. In 2019, more than 200 enterprises signed up for the exhibition, and 61 enterprises showed their latest products and technologies. Among them, 6 enterprises participated in the exhibition for the first time, and about 85% of them brought dozens of physical products for exhibition, all of which were specially decorated. The performance, quality and appearance of the domestic equipment in this exhibition are further improved. In addition to traditional foreign equipment buyers from Russia, Malaysia, Singapore, Germany, India and Japan, the exhibition also invited emerging foreign market buyers from Albania, Switzerland, Estonia, Mexico, Egypt and Kazakhstan to Suzhou. In the three-day exhibition, more than 95% of the exhibitors reached a purchase and sale agreement, and a considerable number of equipment and exhibits were reserved for purchase. All enterprises have achieved good results.


In 2021, the conference will continue to deepen exchanges with international industries, enhance international participation and academic authority, and strengthen exchanges of the latest technologies at home and abroad. The conference will provide a better platform for enterprises, universities and research institutions to publish and exchange products, technologies and management methods, and strive to build the brand of professional seminars in China and even in Asia. The Organizing Committee hopes to unite all relevant units and take advantage of the prosperity of the industry to seek common development with you!
