Abstract: With the development of cities, the urban drainage system also expands.Drainage pipelines generally adopt the form of gravity flow, which leads to deeper and deeper burial depth of downstream drainage pipelines.Moreover, urban drainage pumping stations are mostly located in urban areas, and generally adopt underground burial to reduce the impact on the surrounding environment.Taking into account the above factors, the corresponding burial depth of pumping stations is also becoming deeper and deeper.In order to reasonably select the structural form of Rehe No.2 underground sewage pump station, the finite element method is used to analyze the stress conditions of the three models under the same conditions.The results show that the vertical frame reinforcement has a better effect on the structural wall plate.At the same time, vertical frame structure has better advantages in equipment installation, foundation pit backfilling, and foundation pit occupancy size.Therefore, it is recommended to adopt vertical frame for reinforcement of similar projects.
