Maintenance trolley

The applicable scenarios for maintenance vehicles include: 1) Construction engineering field ① Ground concrete structure maintenance Suitable for the maintenance of concrete poured on building floors, road surfaces, and other surfaces, providing continuous moisture retention and insulation measures through a mobile platform to ensure stable growth of concrete strength. ② Underground engineering maintenance Suitable for underground concrete structures such as basements and underground garages, a closed curing environment can reduce water evaporation, prevent early cracking, and ensure the durability of concrete. 2) Urban and Transportation Engineering ① Bridge and elevated road maintenance Used for the maintenance of high-altitude concrete pouring for bridge piers, elevated bridge decks, etc. The modular design facilitates rapid deployment in complex traffic environments and reduces interference with ground traffic. ② Maintenance of subway tunnel lining Combined with a closed moisturizing system, a stable curing environment can be quickly formed after the construction of subway tunnel lining, preventing concrete surface shrinkage cracks. 3) Construction under special climatic conditions ① High temperature and dry environment In high-temperature areas (such as deserts and arid regions), an automatic sprinkler system is used to maintain the surface humidity of concrete and prevent strength loss caused by rapid evaporation of moisture. ② Low temperature and cold environment Equipped with insulation layer and temperature control equipment, it can provide constant temperature curing conditions for concrete during winter construction, avoiding frost damage and accelerating early strength development. 4) Adaptation to complex construction scenarios ① Maintenance of irregular structures Support the maintenance of irregular concrete structures such as curved walls and curved roofs, and achieve a tight fit with the surface of the structure through adjustable brackets to ensure uniform maintenance. ② Maintenance of large volume concrete For large volume concrete projects such as dams and large equipment foundations, layered and partitioned maintenance management is adopted to effectively control the temperature difference between inside and outside and reduce the risk of temperature cracks. Note: The selection of maintenance vehicles should be based on the project scale, structural type, and environmental conditions. For example, safety protection design should be prioritized for high-altitude operations, while large volume concrete should be matched with temperature and humidity intelligent monitoring systems.
