In construction, relying on attached scaffolding to reduce corporate costs while improving the construction efficiency and safety of high-rise buildings. During the construction phase, when maintaining the concrete entities in the floors, the traditional process is for maintenance personnel to pull the water pipe and spray the concrete to be maintained directly. However, there are the following problems: when the floor area of ​​the building is large, it requires the cooperation of multiple maintenance personnel; manual maintenance leads to uneven and untimely maintenance, and it is easy to cause waste of resources; the main structure construction generally takes a long time, and the cost of special maintenance is high.

The utility model drives the nozzle to move to spray water on the concrete within the range through the folding telescopic rod, and the controller controls the curing progress, which saves manual labor, reduces enterprise costs, improves curing efficiency, and makes concrete curing more timely and comprehensive.

[0004] In the actual application process, the lifting scaffolding has a certain vertical height. As the construction height of the building increases, in order to be able to spray and maintain the inner wall of the lifting scaffolding, it is necessary to install multiple sprinkler pipes evenly and densely on the lifting scaffolding. If the sprinkler pipe is broken or needs to be replaced, the installation and disassembly are more cumbersome; and when multiple sprinkler pipes are spraying water, as the lifting scaffolding rises, the energy consumption required for large-flow water supply to the high-rise is relatively large.
