Analysis of Design Points of Overhead Grille Pool of an Underground Sewage Treatment Plant in Shangluo City

地下式污水处理厂作为一种生态环保的场站建设方式,近年来在我国兴起,并获得了越来越广泛的应用。为了满足水力流程需要,并有效利用地下空间,工艺专业往往将预处理区的格栅池在地下箱体中架空布置。格栅池中部闸墩体型较大,需要依靠梁、柱或墙系统来支撑。闸墩为非杆件结构,需采用弹性力学方法计算。论文提供了一种有限元计算软件分析计算方法,对类似结构设计有一定借鉴意义。

As an ecological and environmental protection plant construction method,underground sewage treatment plant has emerged in China in recent years,and it has been used more and more widely.In order to meet the needs of the hydroelectric process and effectivly use the underground space,in the pretreatment area,the grille pool is often arranged overhead in the underground box.The gate piers in the middle of the grille pool are large in size and need to be supported by beam,column or wall system.The pier is a non-bar structure,which needs to be calculated by elastic mechanics method.This paper provides a finite element software analysis method,which can be used for reference in similar structure design.
