【Abstract】 【Objective】The purpose of this paper is to explore and eliminate the complex problem of the sediment deposition in greenhouse drainpipe, and solve the difficulty of cleaning the sediment deposition in the pipeline during the drainage process of greenhouse roof.【Method】The pressure flow siphon drainage system was applied to clear the silt, and actual engineering cases were combined with the hydraulic calculation to draw the hydraulic calculation diagram and the rainwater bucket pipeline system diagram. Overflow measures was equipped with the installation of rainwater bucket and the selection of drainage riser were introduced for safety.【Result】The pressure flow siphon drainage system was applied in greenhouse, the drainage pipe is simple and the drainage efficiency is high. The horizontal pipe in the pressure flow siphon drainage system has no slope, and the construction work is simple and convenient.【Conclusion】The pressure flow siphon drainage system can not only optimize the spatial layout of the greenhouse drainage pipe, but also effectively discharge the sediment in the pipe, compared to the traditional gravity drainage system. This project case has certain guidance and reference significance for the application of siphon drainage system on greenhouse roof.更多还原
