It is preferred that, the U-bolt is made up of the round steel of Φ 22, and two ends are M22 screw threads.
It is using the beneficial effect produced by above-mentioned technical proposal:
The utility model integrates rail girder method, vertical choose horizontal lift method, D types just beam method for strengthening, continuous construction beam method etc. are a variety of Circuit advantage and disadvantage research and development and go out, disclosure satisfy that high request of the railway to Track regularity, be provided simultaneously with structure it is relatively easy, peace Complete stable, consolidation effect more preferably, the advantages of adapt to smaller double track railway section line spacing and larger span can there is provided one kind The track strengthening device for existing railway of construction below circuit is not influenceed.
1) device is simultaneously using rail girder and D types just beam, and just rail girder is added in girder construction in the D types of high stability, Long area overhead circuit is had higher stability, it is ensured that requirement of the railway to Track regularity, can be very good to ensure line The consolidation effect and traffic safety on road.
2) the crossbeam length that crossbeam shortens former D24 types just beam is improved, can adapt to double track railway section line spacing smaller Situation.
3) longeron of the device, which can meet span and be not more than under 24 meters, wears construction operation.
4) after reinforcing, the construction under row line, such as shield can be entered under conditions of not influenceing traffic safety and not cutting off traffic Structure driving, bridges and culverts jacking etc., save the duration.
