Container House Renovation in Heavy Rain

Container house renovations may face risks such as leakage, waterlogging, and even being washed away during heavy rain. Here's a detailed analysis:

Physical Attributes and Disaster Resistance

As temporary accommodation facilities, the physical attributes of container houses determine their limited ability to withstand extreme weather conditions. Unlike permanent buildings, container houses lack mature drainage systems, waterproof structures, and emergency evacuation routes, making them more of a makeshift solution. During heavy rain and other extreme weather conditions, the roofs and walls of container houses may leak due to the inability to withstand large amounts of rainwater, and the structural integrity of the house may even be compromised due to excessive water accumulation.

Location and Terrain Issues

The location of container houses is also an important factor affecting their disaster resistance. If located in low-lying areas or areas with poor drainage, waterlogging is highly likely to occur during heavy rain. During the Nagoya Asian Games, it was reported that container houses were set up in low-lying areas of the port district, resulting in waterlogging, leakage, and the emergency evacuation of approximately 400 athletes and staff living in the containers due to heavy rain.

Design and Renovation Defects

The design and renovation of container houses may also have defects that further affect their disaster resistance. Some container houses may not have undergone sufficient waterproofing treatment, or their drainage systems may be poorly designed, resulting in ineffective drainage during heavy rain. In addition, the stability of container houses may also be compromised due to improper renovation, increasing the risk of being washed away during heavy rain.

Practical Cases and Lessons

The performance of container houses during heavy rain at the Nagoya Asian Games serves as a typical example. Due to the inadequate estimation of extreme weather by the event organizers, as well as the physical attributes and location issues of the container houses themselves, athletes faced numerous difficulties and safety hazards during the heavy rain. This incident reminds us that when using temporary accommodation facilities such as container houses, their disaster resistance must be fully considered to ensure the safety of personnel.
