摘要
园区应急排水工程设计是城区水系建设的重要依据,涉及市政雨水管道的安全运营,对消除园区雨季排涝安全隐患,解除洪涝灾害给园区内基础设施造成严重的损失威胁具有重大的工程意义。为此,结合南阳市城乡一体化示范区“南阳市月季园东园应急排水及白桐干三支渠恢复工程”项目实践,针对月季园东园应急排水工程设计典型代表东侧排水工程设计展开分析研究。结果表明,认识工程概况,本着尽量利用现状沟渠、少占地的原则,着重就北侧出水口工程、东侧排水沟、排水涵及东沟桥涵工程等五部分完成工程结构设计目标。首先,从北侧出水口布置、倒虹吸水力计算(包括倒虹吸管径计算、倒虹吸管输水能力复核及倒虹吸总水头损失)、工作井设计(主要有工作井深度计算选定与基坑支护设计)、接收井设计、管道结构计算和管道强度计算等六个方面实施北侧出水口工程设计;其次,围绕东侧排水沟、东沟桥涵工程设计(主要包括桥梁桥台承载力验算及排水涵桥台承载力验算)和东侧排水工程相关管线迁建保护设计等三方面完成东侧排水工程其他工程设计。可为类似园区应急排水工程设计提供借鉴参考。
The design of emergency drainage engineering in the park is an important basis for the construction of urban water system,which involves the safe operation of municipal rainwater pipes,and has great engineering significance to eliminate the hidden danger of drainage in the rainy season and remove the threat of serious losses to the infrastructure in the park.Therefore,based on the practice of the"Emergency Drainage and Restoration Project of the Eastern Garden of the Nanyang Rose Garden and the Restoration Project of the Three Supporting Canals of the Baitonggan River"in the Nanyang Urban-Rural Integration Demonstration Zone,this study focuses on the analysis and research of the design of the emergency drainage project in the eastern garden of the Rose Garden.The results show that,based on an understanding of the project overview and following the principles of utilizing existing ditches and occupying less land,the design objectives of the project were mainly achieved through the design of five parts:the northern outlet project,the eastern drainage ditch,the drainage culverts,and the bridges over the eastern ditch.Firstly,the design of the east drainage project shall be implemented from six aspects:the north water outlet layout,calculation of inverted siphon hydraulic(including calculation of inverted siphon diameter,review of inverted siphon water capacity and loss of inverted siphon total head loss),working well design(mainly working well depth calculation and foundation pit support design),receiving well design,pipe structure calculation and pipe strength calculation.Secondly,the design of the eastern drainage ditch and the bridge over the eastern ditch(including calculations for the bearing capacity of the bridge and the drainage culvert bridge)and the design of the relocation and protection of the pipelines related to the eastern drainage project were completed.This study can provide reference and guidance for the design of similar emergency drainage projects in parks.
