China Construction machinery information

reliable and safe good news! On August 25, the Ministry of science and technology of the people's Republic of China held a project acceptance meeting on "research and development and demonstration application of key technologies for the construction machinery industry" made of high-strength corrosion-resistant alloy steel in Beijing. The scientific research project of "Research on Key Technologies of complete equipment for pre slotted tunnel construction" undertaken by China railway construction heavy industry Co., Ltd. was unanimously approved by on-site review experts, which marked that China railway construction heavy industry Co., Ltd. handed over a "answer sheet" of scientific research satisfaction to the country

the pre grooving machine passed the review, and China railway construction heavy industry Co., Ltd. gave a satisfactory "answer sheet"

"Research on key technology of pre grooving tunnel construction equipment" was approved by the "National Science and technology support plan" in 2013. In combination with the outline of the national medium and long term scientific and technological development plan and the major needs of domestic projects, CRCC heavy industry aims at the technical problems of weak surrounding rock construction, drives the progress of construction methods with the innovation of construction equipment, breaks through the key technologies such as the overall design technology of pre grooving machine, concrete proportioning technology, tool cutting performance analysis and layout design technology, pre grooving construction method, and successfully develops the pre grooving machine with independent intellectual property rights, The overall technology of this machine has reached the international advanced level, and it is playing an important role in the construction of Menghua railway, the largest dedicated coal transportation line in China

at the review meeting on the same day, after many strict review links such as "reporting, inquiry, discussion and financial inspection", the scientific research project finally received unanimous praise from experts, which is also the first scientific research project accepted by the Ministry of science and technology of the people's Republic of China. It is reported that the scientific research project is led by China Railway Construction Corporation, actually undertaken by China railway construction heavy industry, with the participation of China Railway First Research Institute and Central South University. After more than three years of joint research and development, various task indicators have been completed. A total of 22 patents have been applied for, including 9 invention patents, and one national standard for the product has been led

at present, CRCC heavy industry, supported by the technology of this scientific research project, has established a technological innovation system with enterprises as the main body and a scientific research and production base of pre grooving machine. It has cooperated with universities and design institutes to cultivate technical talents for the research of construction equipment and construction methods in weak surrounding rock for the country, and is committed to promoting the development of China's high-end equipment manufacturing industry and improving the overall technical level of full face mechanized excavation of tunnels in weak surrounding rock
