Embodiment Construction
[0039] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0040] like Figure 1-4 The shown anti-backflow drainage and drainage device for urban subway is used to improve the drainage and drainage facilities at the entrance and exit of the subway station, improve the automation degree of emergency drainage and drainage treatment, and prevent rainwater from being poured into the subway station. The urban subway anti-backflow drainage device uses an inflated pop-up airbag. When the rainfall increases sharply, the monitor receives the water level information and reaches the specified water level line. , to protect the internal structure of the subway station and prevent rainwater from pouring back. The rainwater monitoring system has a high degree of automation and does not require human intervention. It realizes the intelligent operation of the system, saves manpower and material resources, improves...
