The most difficult!The technical achievements of Harbin Institute of Technology helped the construction

August 24

As an important part of the Hay High -speed Railway Iraqi Section Project

Yichunxi Station, the northernmost high -speed rail station in my country

Formally start

Refresh the latitude of my country's high -speed rail construction again

Team of Ling Xianchang, School of Turkey Engineering, Our School

Research and development of frozen damage prevention and control technology results

It will be applied for the first time in the construction of high -speed rail stations

Create the extreme cold area of ​​high latitudes in my country and the world

High -speed rail construction is the most difficult

"News Broadcast" report of Central Radio and Television Station

The Hiyi High -speed Railway Section is located in the central part of Heilongjiang Province. The line starts from Tieli City to Yichun City. The total length is 111.4 kilometers. The line design speed is 250 kilometers per hour. station. Yichunxi Station is the largest station building across the board, which can accommodate 1,500 passengers waiting at the same time. It is the high -speed railway station building in my country that has the highest latitudes in the latitude, the largest temperature difference between the annual temperature difference in the area in the high -cold region, The first high -speed rail project in the domestic station building uses a prefabricated railway.

Yichun West Station Construction Site

Professor Ling Xianchang has long been committed to research on frozen soil dynamics and frozen soil engineering, soil dynamic and geotechnical earthquake engineering, underground geotechnical and subway engineering, and engineering geological disaster reduction. The technical achievements applied to the high -speed rail construction of high -cold districts are the further development and expansion of the second prize of the 2017 National Technology Invention Award.

There are multiple island -shaped frozen soil belts along the Hiyi high -speed railway section. The thickness of the frozen soil layer at the construction site of Yichun West Station is 2.9 meters. The sensitivity of frozen and swelling is high and stable, which brings great difficulty to the construction. In order to be effective and fundamentally solved the problem of ground -rating damage prevention and control, China Railway Construction Group Co., Ltd. and the team of Professor Ling Xianchang in our school for the first time carried out research on new technical topics of anti -frost dampery -based gel materials. The implementation of solidification and dense reinforcement can be implemented to achieve the prevention and control of ground -rated damage. This is also the first world in the world to use high -performance material technology to solve high -cold area high -speed railway stations in high -cold -free and sensitive water -rich and soft land -based ricious control and stable control and stable control, which has accumulated valuable experience for the construction of similar projects in my country.

Professor Ling Xianchang explained the technical achievements at the construction site

Professor Ling Xianchang accepted interview with CCTV reporters

After the completion of the Hari High -speed Railway, the running time of passenger trains from Harbin to Yichun will be shortened from about 7 hours to within 2 hours, forming two or three hours of transportation circles centered on Harbin, and giving full play to the construction of the railway construction to drive the Longjiang economy. Growing and promoting the basic and critical role of regional coordinated development is of great significance.
