Flood Prevention System Construction and Innovative Equipment Application in Metro Engineering

Abstract

Objective In recent years, extreme rainfall weather frequently causes urban flooding, leading to many cases of metro engineering project water disasters, significant economic losses and personnel casualties. It is essential to develop scientifically sound anti-backflow measures and construct an effective flood prevention system. However, current research on underground spaces both in China and worldwide primarily focuses on forecasting and risk assessment of flooding disasters, failing to form a comprehensive flood prevention system. Moreover, commonly used anti-backflow measures in metro engineering, such as setting steps and reverse-slopes at metro entrance or equipping with removable flood prevention barriers and sandbags, have drawbacks including the need for long-term personnel monitoring, inconvenient use, and delayed response. Method Through investigation, adhering to the principle of ′prevention as the mainstay and drainage as the supplement′, a comprehensive flood prevention system for metro engineering is summarized, covering aspects of metro stations, interval tunnels, vehicle depots, coordination mechanisms, disaster prevention plans, and design standard improvements. Result & Conclusion Addressing the shortcomings of existing anti-backflow measures, an intelligent flood prevention equipment is proposed. This equipment can manage access, provide on-site manual control, on-site automatic flood prevention, remote control, emergency manual control, and safety assistance. It can be applied to new metro stations, existing station renovations, underground garages, underground shopping malls, ensuring the safety of personnel and property.
