Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to a U-shaped trough retaining wall type underpass water collection facility. Background Technology

[0002] In urban underpass drainage systems, the drainage capacity of pumping stations depends not only on the pump set's lifting capacity and the design of the outlet pipeline, but also, and perhaps more importantly, on an efficient and reliable water collection system. The pump set's lifting capacity, the outlet pipeline design, and the efficient water collection system all significantly impact the pumping station's drainage capacity. A current problem is that existing technologies often focus too much on the pumping station's lifting capacity and outlet pipeline modifications, neglecting the optimization of the water collection system. This leads to low actual operating efficiency of the pumping stations and poor drainage. This tendency to prioritize pumping stations over water collection may prevent the effective resolution of urban flooding problems, as the water collection system plays a crucial role in the drainage system. Therefore, we propose a U-shaped trough retaining wall type underpass water collection facility to ensure efficient collection of rainwater and its guidance to the pumping station.
