Container Houses in Earthquakes

Container houses in earthquakes have advantages such as strong earthquake resistance, rapid construction, complete functionality, ease of transportation and installation, and adaptability to harsh environments. Details are as follows:

Superior Earthquake Resistance
Container houses use steel structural frames, which have high structural strength and toughness. For example, prefabricated concrete houses (with an appearance similar to containers) remained stable through multiple aftershocks in the Ludian earthquake in Yunnan, with their earthquake resistance being eight times that of traditional brick-and-concrete structures. Foldable container houses also have fire-resistant and earthquake-resistant properties, providing safe shelters for people in disaster areas.

Efficient Construction and Installation
Container houses can be rapidly deployed to meet urgent resettlement needs. For example, the "earthquake shelter蜗居" developed in Japan can be transported by helicopter or truck and has a built-in inflator pump that allows it to quickly expand into a two-story building in just four and a half minutes. The installation process for foldable container houses is even faster, with three people able to complete the installation in five minutes, using just eight screws to secure each foldable unit.

Comprehensive Functional Design
Container houses integrate various living facilities inside, supporting long-term self-sufficient living. For example, the "earthquake shelter蜗居" is equipped with a solar power generation system, lithium-ion battery energy storage devices, a water maker, a food storage area, a simple kitchen, shower facilities, and a microbial decomposition toilet, allowing two adults to live for one month. The container houses installed after the earthquake in Jishishan County, Linxia, Gansu, have pre-installed water and electricity pipelines, multiple power outlets, fluorescent lights, curtains, sanitary facilities, and electrical appliances, allowing residents to move in with furniture and start using them immediately.

Flexible Transportation and Installation
The modular design of container houses facilitates long-distance transportation and flexible deployment. For example, foldable container houses, when folded, have a height of only 42 centimeters, and a 17.5-meter truck can carry 20 of them, making them suitable for both sea and land transportation. The container houses donated by Qatar to Turkey were transported by truck to the port and then delivered to the disaster area by sea.

Adaptability to Harsh Environments
Container houses can withstand extreme conditions such as high altitudes, extreme cold, and strong winds. For example, after the earthquake in Xigaze, Tibet, the container houses supported by China Communications Construction Group took into account the strong winds and low temperatures in the earthquake zone, adopting design principles of safety, comfort, and speed. The container houses in Jishishan County, Linxia, Gansu, ensure stability through concrete piers and steel cables, resisting low-temperature environments.
