How to prevent underground parking lots from flooding

Preventing underground parking lot flooding requires comprehensive consideration of multiple aspects. Here are some suggestions:

Waterproof design: The waterproof design of underground parking lots should follow the principle of "combining prevention, drainage, interception, and blocking, balancing rigidity and flexibility, adapting to local conditions, and comprehensive management". In the design phase, factors such as groundwater level and rainfall should be fully considered, and appropriate waterproof materials and measures should be taken, such as using waterproof coatings or floor waterproof materials to coat the ground and bottom plate to improve waterproof ability.

Drainage system: Ensure that the drainage system of the underground parking lot is unobstructed. This includes inspecting and maintaining equipment such as underground water pumps and drainage pipelines to ensure their normal operation. At the same time, it is possible to consider installing additional drainage systems or reinforcing existing drainage systems to cope with situations where the groundwater level is too high or rainfall drainage is not smooth. Could also use some freestanding flood barrier, temporary flood boxwall and water active flood bags to better prevent flooding.

Interception measures: Drainage ditches, flood interception ditches, and drainage systems should be set up on the surface of the underground parking lot to quickly drain surface water and rainwater, prevent and reduce rainwater from entering the underground parking lot.

Waterproof gates and grooves: Install waterproof gates or grooves at the entrances and exits of underground parking lots to prevent rainwater from entering. These facilities can play an important role during heavy rainfall weather.

Emergency plan: Develop an emergency plan for underground parking lot flooding, clarify responsible persons and flood season duty system, and conduct drills on the emergency plan. During heavy rainfall, according to meteorological warnings and notifications from relevant departments, timely activate emergency plans and actively organize flood control and drainage work for underground parking lots.

Patrol and duty: Strengthen patrol and duty work during rainy periods, timely detect and handle water immersion problems. When a dangerous situation occurs, the on duty personnel should immediately send the alarm information to the residents in a timely manner, and the management personnel should coordinate and guide the owners to drive their vehicles out of the garage one by one and move them to a higher place for parking.

Property management: Property companies should estimate and prevent disasters, promptly notify owners, and handle disaster situations. In the design and construction process of underground parking lots, property management companies should supervise and ensure that developers carry out construction in accordance with waterproofing requirements.
