100 representatives from 30 units discussed new technologies, new equipment and new practices of geotechnical and underground engineering, The first domestic open shield machine developed by the group was used in Jilin pine diversion and water supply project

from April 23 to 24, a cross industry academic seminar - "Symposium on new technologies and new equipment for geotechnical and underground engineering", jointly sponsored by Beijing Rail Transit architecture society and Jilin University and hosted by China railway construction heavy industry group, was held in Changchun. Nearly 30 units and 100 representatives from Jilin University, Liaoning Provincial Transportation Planning and Design Institute, Jilin provincial transportation planning and Design Institute, water and Soil Conservation Bureau of Songliao Commission, No. 1 Water Conservancy Bureau and other units attended the seminar. Xu Heping, Deputy Secretary General of Beijing Railway Construction Association, sunyouhong, Dean of the school of construction engineering of Jilin University, zhouhaixiang, general manager of railway construction heavy industry group, and other leaders attended the meeting and delivered speeches

in the process of reduction, Zhou Haixiang, general manager of the group, spoke at the seminar on behalf of the group. He spoke highly of the northern headquarters of the group for holding a seminar on cooperation among associations, schools and enterprises to explore "new technologies, new equipment and new practices" of geotechnical and underground engineering, and for establishing and improving the marketing market through the form of the seminar

the meeting invited eight technical experts from China railway construction heavy industry group, Jilin University, China Railway 18th Bureau and other units to focus on the construction technology and equipment of the new cement soil structure underground diaphragm wall, the research on the new composite rock drill bit, the stability evaluation of the surrounding rock of the tunnel and the research on the support countermeasures, the key technologies for the design and construction of Jilin pine diversion water supply project, the key technologies for the design and construction of Changchun metro The development status and trend of mechanical tunneling technology and other geotechnical and underground projects made a special report on the latest achievements of track and water conservancy infrastructure. After unloading, there was a stopover report, including the national "863 Plan" natural science foundation project, which showed the new technology, new construction methods, new equipment and new technological progress of geotechnical and underground engineering in China

On the 24th, the participants jointly investigated the use of the first domestic open shield machine developed by the group in Jilin pine diversion and water supply project. The delegates came to the "body" of TBM by taking the special underground "battery car". They were shocked by the working condition of modern equipment in the tunnel. Many people praised it while asking curiously how the equipment operated, and many people kept taking photos. Wangshouhui, deputy general manager of the group, introduced to the visitors that the equipment has been successfully excavated for 400 meters, which shows that the performance of the equipment has fully reached the world's most advanced level, and also marks a new breakthrough in the first set of national major equipment

after discussion and on-site investigation, leaders, experts and scholars in the three fields of track, water conservancy and highway construction agree that the national strategies of the new government such as the "the Belt and Road" provide a broad space for the development of new construction methods, new technologies and new equipment, which will greatly promote the innovation of construction methods, construction technologies and equipment; Focusing on the theme of "new technology and new equipment of geotechnical and underground engineering", cross industry discussions have been carried out, expanding the scope of application of new technologies, new construction methods and new equipment, which has also laid a foundation for further production, learning and research cooperation; In the future, enterprises should be good at capturing the opportunities brought by structural adjustment and policies, increase independent innovation, actively integrate resources, and build a broad exchange platform on the basis of introducing, digesting and absorbing foreign advanced technology, so as to jointly contribute to the construction and development of rail, water conservancy and highway in China and even the world
