LI MINHUI / LI SHAOHUI / XU KONGBIN / ZHAO HONG / SONG TINGTING

The invention provides a ballast bed and a manufacturing method thereof, and the ballast bed comprises a plurality of ballast bed slabs which are sequentially connected end to end, a limiting boss arranged between two adjacent ballast bed slabs, and a buffer base plate arranged between the limiting boss and the ballast bed slabs, so that the two adjacent ballast bed slabs can be transversely limited; and the hard contact between the limiting boss and the roadbed slab is cut off, so that the end part of the roadbed slab and the limiting boss can be prevented from being damaged or even invalid when being impacted. Furthermore, due to the fact that the enclosed buffer base plate is arranged in the two limiting grooves firstly, then the limiting bosses are formed in the two limiting grooves provided with the buffer base plate in a pouring mode, the buffer base plate and the limiting bosses are integrated, and compared with the mode that the bosses are manufactured firstly and then the buffer cushion is installed in the prior art, the buffer base plate is installed more conveniently and rapidly, and the installation efficiency is improved. And the connection of the buffer base plates is firmer and more reliable, the construction process is greatly simplified while the good transverse limiting function is achieved, and the construction period of the track is shortened.

本发明提供一种道床及其制造方法，包括多块依次首尾相接的道床板、设置在相邻两块道床板之间的限位凸台以及设置在限位凸台和道床板之间的缓冲垫板，因此能够对相邻两块道床板起到横向限位作用，且隔断了限位凸台和道床板之间的硬接触，能够避免道床板端部及限位凸台在经受冲击时发生损坏甚至失效。进一步，由于先在两个限位凹槽中设置围合的缓冲垫板，再在设置有缓冲垫板的两个限位凹槽中浇筑形成限位凸台，使缓冲垫板和限位凸台形成一体，相较于现有技术中先制造凸台、再安装缓冲垫的形式，不仅缓冲垫板的安装更为方便快捷，且缓冲垫板的连接也更为牢固可靠，在实现良好横向限位功能的同时还大大简化了施工流程，缩短了轨道施工的工期。
