Problems solved by technology

[0002] In the current ballastless track construction, the concrete base is poured first, then the track bed is constructed, and the track bed concrete is poured on site after the track is adjusted in place. This kind of construction project has the disadvantages of many contents, complicated procedures, long construction period and low efficiency. , so under the existing technology, prefabricated track bed is often used instead of cast-in-place track bed, so as to increase the construction speed
At present, it is also necessary to adjust it when laying the prefabricated track bed, and the adjustment device under the prior art is generally laid on the outside of the prefabricated track bed, and before pouring the concrete base, it is necessary to install another protective device to ensure the removal of the adjustment device. very inconvenient

Abstract

The invention relates to a built-in adjusting device used for adjusting a prefabricated rail ballast bed. The built-in adjusting device is characterized in that a pair of positioning holes (3a) are formed in symmetrical positions of the prefabricated rail ballast bed (3) respectively; the axes of the positioning holes are vertically and downwards formed; each positioning hole (3a) is internally provided with a supporting sleeve (2); each supporting sleeve (2) is internally provided with a jacking device (1) which is in screw-thread fit with the supporting sleeve (2); the bottom end of each jacking device (1) is provided with an ejection rod (6) which is coaxially matched with the jacking device (1); and after the bottom end of each ejection rod (6) penetrates through each supporting sleeve (2), the ejection rod (6) is matched with and tightly jacks against a shield pipe piece (10). The built-in adjusting device used for adjusting the prefabricated rail ballast bed has the beneficial effects of simple structure and high adjusting precision, and has the characteristics of relatively high safety, convenience for loading and unloading, and strong adaptability.
