【摘要】 以龙岗河干流初期雨水的调蓄设施工程为实例,计算了初期雨水调蓄设施的雨水处理规模和调蓄容积,分析了敞开式和封闭式调蓄池的优缺点,对水力翻斗和人工清淤两种清淤方式进行了比选。结果表明,敞开式调蓄池和水力翻斗清淤更有利于调蓄设施的管理维护,且节约经济成本。龙岗河初期雨水处理调蓄系统的设计和实施对实现经济环境和谐发展具有重要意义,可供类似工程参考。更多还原

【Abstract】 Taking the project of the initial rainwater storage facilities for the main-stream of Longganghe River as an actual case,the scale of the rainwater treatment and the volume capacity of the storage for the initial rainwater storage facilities are calculated,and then the merits and defects of both the open detention pond and closed detention pond are analyzed,while a comparative selection is made between the desilting modes of hydraulic dumping and manual desilting.The result shows that the open detention pond with the desilting of hydraulic dumping is more favorable for the management and maintenance of the rainwater storage facilities along with a certain economic cost saving.The design and implement of the storage system for the initial rainwater treatment of Longganghe River have an important significance for realizing the harmonious development of economy and environment therein,and then can provide a reference for the similar projects concerned as well.更多还原
