The existing high-speed railway adopts a concrete slab as a track slab, and the high-speed railway is fixed on the concrete slab. The better the foundation of the high-speed rail is, the smaller the vibration is during the running of the high-speed rail, the more stable the running is, and the faster the speed is. In order to ensure that the train can stably, reliably and quickly run on the track, higher requirements are also put forward on the high-speed rail plates. Meanwhile, along with the release of the 'new era traffic national railway advanced planning outline', the development targets and main tasks of the Chinese railway in 2035 and 2050 are defined. The high-speed rail network and the common-speed rail network which take eight longitudinal and eight transverse as main channels are further optimized and perfected. Therefore, under the background of the dual tasks, the research and the application of the high-speed railway track slab become urgent matters for embodying the high-speed railway technical level in China and highlighting the national reality.

Although the existing automatic processing equipment for the steel bars is mature, the work such as raw material pretreatment, construction, welding, binding and the like of the steel bar cage is manually performed or interfered according to the related size requirements of the ballastless track plate and the steel bar cage of the high-speed railway, the labor intensity of workers is high, the production precision is difficult to control, and the phenomenon of skewing of the steel bar cage occurs.
The applicant finds that in order to solve the technical problem that full-automatic production of the track slab reinforcement cage cannot be realized in the prior art, in the automatic production process, the applicant creatively divides the high-speed railway ballastless track slab reinforcement cage into an upper part and a lower part in advance, respectively prepares an upper layer reinforcement cage and a lower layer reinforcement cage through specific preparation processes which are mutually noninterfere, then performs automatic cage combination and automatic reinforcement treatment on the upper layer reinforcement cage and the lower layer reinforcement cage, and finally prepares the finished reinforcement cage. However, in the prior art, a process method for dividing the reinforcement cage into an upper part and a lower part for prefabricating the reinforcement cage is not disclosed, and automatic cage combination treatment cannot be performed on the upper part and the lower part of the reinforcement cage. Further, in actual operation, the applicant has the technical difficulties that the upper layer reinforcement cage and the lower layer reinforcement cage cannot be aligned accurately, cannot be bound effectively and the like in the automatic cage closing and reinforcing processes of the upper layer reinforcement cage and the lower layer reinforcement cage.
