8. A smart rail train road structure as claimed in claim 6, wherein: the reinforcing plate (35) is triangular, wherein a first side edge of the reinforcing plate (35) is fixedly connected with the transverse plate body (33) and extends to the end part of a second end of the transverse plate body (33); the second side edge of the reinforcing plate (35) is fixedly connected with the vertical wall body (32) and extends to the end part of one end, far away from the transverse plate body (33), of the vertical wall body (32).
9. The smart rail train road structure of claim 1, wherein: the intelligent rail train road structure comprises a signal transceiver; the signal transceiver is buried in the anti-collision wall (4) to determine the relative position of the intelligent rail train and the anti-collision wall (4) at present.
10. The smart rail train road structure of claim 1, wherein: the horizontal height of the middle part of the main road (1) is higher than the horizontal heights of the two sides; and/or the presence of a gas in the gas,
the height of one side of the auxiliary road (2) far away from the main road (1) is lower than that of one side of the auxiliary road (2) close to the main road (1).
11. The smart rail train road structure of claim 1, wherein: the main road (1) comprises a base (11) and a reverse filtering layer (12), wherein the reverse filtering layer (12) is arranged on the side part of the base (11), and a retaining wall surface (31) of the retaining wall (3) is abutted to the reverse filtering layer (12).
12. The smart rail train road structure of claim 1, wherein: the main road (1) comprises a pavement layer (13), the pavement layer (13) is arranged at the top end of the base (11), and the top end of the retaining wall (3) extends upwards to a position which is not lower than the height of the pavement layer (13); the pavement layer (13) is coated with traffic marks for intelligent train identification.
13. A construction method of a smart rail train road structure as claimed in any one of claims 1 to 12, comprising:
constructing a side road (2) on the roadbed;
pouring retaining walls (3) on the side parts of the auxiliary roads (2);
filling a main road (1) on one side of the retaining wall (3) far away from the auxiliary road (2);
and pouring an anti-collision wall (4) at the top end of the retaining wall (3).
