construction site
according to zhao huanmin, the person in charge of the binsui railway rectification project of the china railway 22nd bureau, because the upstream and downstream bridges on this railway section were built early and had low construction standards, many cracks, piers, columns and beams have appeared on the bridge after years of operation and erosion of the natural environment. the body is deformed, posing a great potential risk to driving safety. the project technical team refined the reasonable and feasible construction plan and used bim technology to simulate various construction conditions to avoid safety and quality problems such as errors, leaks, and collisions. they used the "traffic skylight" time to dismantle old beams hole by hole and jack in new frames. , maintaining the existing railway yard.
during national day, construction workers worked overtime to catch up on the project
it is understood that after the completion of the project, the driving speed between pingshan and maoershan will be increased from the original designed speed of 60 kilometers per hour to 120 kilometers per hour, which will effectively alleviate the growing demand for passenger and freight transportation from harbin to suifenhe and significantly improve the existing railway bridge. transportation capabilities.
