摘要
为提高水资源的利用效率,城市供水系统通常采用集中取水方式,使取水泵房平面尺寸、埋置深度显著增大。文章结合工程实例,综合考虑工艺要求、地形条件、地质特征、施工方法、结构受力等因素,对取水泵房不同围护方案进行比较,最终选定沉井布置方案,并重点介绍了超大矩形沉井布置要点,以期为类似工程提供参考。
In order to improve the utilization efficiency of water resources,the urban water supply system usually adopts the centralized water intake mode,which significantly increases the plane size and buried depth of the water intake pump house.Combined with the engineering example,this paper comprehensively considers the process requirements,topographic conditions,geological characteristics,construction methods,structural force and other factors,compares different retaining schemes for the water intake pump house,and finally selects the open caisson layout scheme.It focuses on the layout points of the super-large rectangular open caisson,in order to provide reference for similar engineering.
