摘要
通过对深圳某剧场下沉广场排水形式进行对比分析,理清了下沉广场区域重力排水和压力排水的边界条件。采用重力排水时需要考虑的影响因素较压力排水要多,条件也相对严格,特别是采用重力排水时要详细考证上下游重现期、雨水量及下游排水管径对设计排放效果的影响。本文对这些因素进行了严致的计算分析,并提出了相应的解决方案。
Through the comparison and analysis of the drainage form of a theater sink square in Shenzhen,the boundary conditions of gravity drainage and pressure drainage are clarified. Compared with pressure drainage,more factors should be considered when adopting gravity drainage,and the conditions are relatively strict. The influence of upstream and downstream recurrence period,rainfall and downstream drainage pipe diameter on designed drainage effect should be studied in detail especially when gravity drainage is adopted. In this paper,these factors are strictly calculated and analyzed,and corresponding solutions are put forward.
