In concrete maintenance, watering is an important construction process. In order to ensure the construction quality, concrete maintenance watering must be strictly controlled.

[0003] In the process of water treatment, existing sewage treatment plants need to set up narrow canals for water diversion or drainage. When constructing such narrow canals, manual watering is generally used for maintenance. Due to the ultra-long, ultra-high and ultra-thin characteristics of the pool wall of the structure, manual watering requires a lot of manpower, and there are problems such as inconvenience in walking, untimely and uneven watering, which cannot meet the humidity requirements of concrete maintenance. Therefore, some construction sites introduced a spray maintenance system, but the spray pipe is difficult to fix in the unfinished canal. The existing technology mostly places the spray pipe at the bottom of the narrow canal. This method limits the spray range and can only maintain the bottom and the lower pool wall. The maintenance is not in place directly below the spray pipe and above the pool wall, and the spray effect is uneven, affecting the quality of concrete. Utility Model Content
