The utility model relates to a tunnel lining maintenance technical field provides a tunnel lining maintenance platform truck. This maintenance platform truck is equipped with a plurality of heating device, a plurality of atomizer and corresponds a plurality of temperature -detecting device and a plurality of humidity detection device who sets up including outer hunch and controller, the outer outside of encircleing, and heating device is used for through the inner wall formation heating of thermal -radiating form to tunnel lining, and atomizer is used for the inner wall spraying to tunnel lining, the controller is used for according to each temperature, every heating device's of psychrometric means feedack control heating temperature and every atomizer's spraying volume. The intelligent control of temperature and humidity not only can be realized to this maintenance platform truck, adds nice and warm humidification two in addition and grows hand protector section mutual independence, each other does not influence each other between temperature curing condition and the humidity curing condition, consequently can to each regional accurate control who realizes the temperature and humidity, finally can show improvement tunnel lining quality, concrete intensity and surperficial compactness according to the different demands of different zone.
