September 12，2023 National Transportation Science and Technology Demonstration Project Site Promotion Meeting Successfully Held in Pingdingshan City，The theme of this event is“Science and technology enabling demonstration project，Innovation Leads Transportation Development”。

Member of the Party Group of the Ministry of Transport、Vice Minister Wang Gang attended the promotion meeting and delivered a speech.。Wang Gang stressed，In order to speed up scientific and technological innovation and digital transformation in the field of transportation，It is an important measure to build a strong transportation country.。It calls for the in-depth implementation of the spirit of the National Conference on Scientific and Technological Innovation in Transportation.，Further play the leading role of science and technology demonstration projects，Insist on demand-oriented、Apply traction、Main body of the enterprise、Talent support，Create a new situation of scientific and technological innovation in the industry。During the on-site meeting, Wang Gang of the Deputy Minister of Ministry of Transport.、Gao Jianli, Director of Henan Provincial Communications Department、Song Huadong, deputy director of the Henan Provincial Communications Department, and other leaders braved the rain to arrive at the Rufang Expressway, which was constructed by the China Railway Fourth Bureau Group Company.ZH2-2 Work areaK42 Observation and guidance on the construction site of water-stabilized paving。

The water-stabilized paver at the site was installed.Topcon 3D mmGPSPaving control system，The system is based on one-to-many millimeter domain laser control technology and satellite real-time differential precise positioning.，Combine 3DDigital modeling、Hydraulic automation control and wireless communication technologies，The road can beBIMAdvanced Digital Paving Solution Using Modeling Technology Directly for Construction Machinery Control。There is no need to measure and set out in advance for water stable paving.、Smash pile, hang line and erect guide beam，Substantially reduce the input of labor force，Reduce the potential safety hazard of man-machine cross operation，At that same time, the influence of human factor on the smoothness of the road is avoided,、Impact of key data such as elevation，Improve the elevation accuracy of water-stabilized paving construction to millimeter level，It can improve the paving quality at the same time，It can effectively avoid the waste of high-quality materials。

During the on-site observation，Vice Minister Wang Gang stayed by the paver for a long time.，And detailed inquiries and understanding of the site construction.，At the same time, the importance of construction process control and quality inspection means is emphasized.，And point out that digitization、The advanced technologies represented by intellectualization need to adapt to different projects and multiple working conditions.、The Importance and Necessity of Multiple Scenarios。

China Railway Siju Group Co., Ltd. is a large construction enterprise with comprehensive construction capacity.，Hold the railway、Highway、Building construction、Special Grade Qualification for General Contracting of 4 Construction Projects of Municipal Public Works and Grade A of Railway Industry(II)Level、Grade A in highway industry、Grade A in municipal industry、Grade A in the construction industry、Landscape Architecture Special Class A、Geotechnical engineering(Survey)Class a、Surveying and Mapping Class A and other 7 designs、Survey、Grade A qualification of surveying and mapping，It is one of the few construction industries in the country.、The only one in Anhui Province“Four special seven armour”Construction enterprises。China Railway Siju Group is also the first company in China to introduce Topcon 3D mmGPSConstruction enterprises of paving system，Topcon 3 was officially adopted in 2012DPaving Control System Used in Paving Construction of Donghai Bosch Proving Ground，Finally, the flatness of the test run is controlled at 3mmWithin、Smoothness error reaches 2mm/4mQuality control and acceptance requirements of equal high standards，Good construction effect has been achieved.。

So far，Along Taihang Expressway in Henan Province（Anyang section）、Shangluo Expressway、Zhounan Expressway、Jiaozuo-Tangshan Expressway and other new expressway projects，Topcon 3DThe paving control system is used for water-stabilized paving construction.。Topcon 3DFurther application of paving control system in this project，It is the practice of digital transformation in the traffic construction industry of Henan Province.，Actively respond to the important measures and performance of building a strong transportation country。
