6. A method of prefabricating a segmented beam according to claim 4, wherein: in the step S4, the method for milling the plane of the tooth end of the segment Liang Aojian by using the engraving robot includes: when the intensity of the segment beam in the steam curing station reaches the set intensity, milling is carried out on one end of the segment beam corresponding to the concave key teeth by using the engraving robot.
7. A method of prefabricating a segmented beam according to claim 6, wherein: the set strength is 40% -50% of the curing completion strength.
8. A method of prefabricating a segmented beam according to claim 3, wherein: in the step S2, the method for transferring to the steam curing station for curing includes: and a guide rail arranged along the longitudinal direction of the segment beam is paved between the prefabrication station and the steam curing station, and after the segment beam prefabrication is completed in the prefabrication station, the segment beam and the end mould are transferred to the steam curing station along the guide rail.
9. A method of prefabricating a segmented beam according to claim 8, wherein: the method for pouring the plane at the end part corresponding to the segment Liang Aojian tooth by using the plane end mould template comprises the following steps: and (3) building a trolley on the guide rail, fixing the plane end die template on the trolley, and pouring the plane end corresponding to the segment Liang Aojian teeth by using a longitudinal jack on the trolley to drive the plane end die template.
10. A method of prefabricating a segmented beam according to claim 6, wherein: the method for milling one end of the segment beam corresponding to the concave key tooth by using the engraving robot comprises the following steps: the cutting method comprises the steps that a feed path is preset in the engraving robot according to the requirements of the key tooth structure of the segment Liang Ao, and the engraving robot automatically mills the planar end part of the segment beam according to the preset feed path.
