Landscape design and construction both affect the landscape of landscaping, and the selection and arrangement of sprinkler heads of sprinkler systems are related to the maintenance and management of gardens.
1. In the selection of sprinkler head, in addition to its own performance, such as working pressure, flow rate, range, combined sprinkler irrigation intensity and whether sprinkler sector Angle can be adjusted, factors such as soil allowable sprinkler irrigation intensity, block size and shape, water source conditions, user requirements, etc., must also be considered.In addition, in the same project or the same wheel irrigation group of a project, it is better to choose a type or similar performance of sprinkler head, so as to facilitate the control of irrigation uniformity and the operation and management of the whole system.In the existing projects, some sprinkler heads with different performance have been installed for one-sided pursuit of waterscape effect, which makes the uniformity of irrigation impossible to be guaranteed.
2.When choosing sprinkler heads, it is important to note that irrigation systems are not fountains, but are designed to compensate for the lack of time and space needed by plants, rather than to create artificial water features.Therefore, the landscape effect can only be taken into account on the premise of first meeting the water demand.There are various kinds of these nozzles. According to the range, there are small range nozzles of 0.6 ~ 5.8 meters, medium range nozzles of 4.3 ~ 9.1 meters, medium range nozzles of 8.5 ~ 15.9 meters, and large range nozzles of more than 20 meters.According to spraying type, there are scattering sprinkler head, ray sprinkler head, rotating sprinkler head and ray rotating sprinkler head.According to the use occasions, there are garden sprinkler, golf sprinkler and so on.These nozzles can automatically pop out of the ground when pressurized spraying water, and retract into the ground when the irrigation stops, which will not affect the mechanical operation.
