| Abstract: |
| 【objective】The purpose of this paper is to explore and solve the problem of sediment dep-osition in greenh-ouse drainpipe.【method】 combined with actual engineering cases, aiming at the proble-m that the sediment deposition in the pipeline during the drainage process of greenhouse roof could not be cleaned, hydraulic calculation was carried out by applying the pressure flow siphon drainage system to c-lear the silt, and the hydraulic calculation diagram and the rainw-ater bucket pipeline system diagram were made.【result】 the pressure flow siphon drainage system is applied in greenho-use, the drainage pi-pe is simple and the drainage efficiency is high.【conclusion】 the pressure flow siphon drainage sys-tem can not only optimize the spatial layout of the greenhouse drainage pipe, but also effectively discharge t-he sediment in the pipe.This project case has certain guidance and reference significance for the applicati-on of siphon drainage system on greenhouse roof. |
