In order to ensure the quality of the shield segment, effective maintenance treatment is needed during production. The traditional maintenance methods mainly include natural maintenance and water maintenance, but these methods have problems such as long maintenance period and difficulty in accurately controlling temperature and humidity, which leads to the fact that the strength and durability of the segment cannot reach the best state.

[0003] However, the existing steam curing device mainly adopts a single-point spraying mode. Although this mode can improve the curing efficiency to a certain extent, the temperature and humidity distribution in the curing chamber is uneven due to the single spraying point, which cannot meet the high-precision maintenance requirements of the shield segment.
