how to build an underground house

The depth of the underground safe house depended on its design requirements and purpose. Generally speaking, the depth of the underground safe house was between 17 and 27 meters underground, but there were also opinions that the first wave of nuclear weapons could be avoided if the depth reached 50 meters. In order to deal with natural disasters, terrorist attacks, electromagnetic pulses and other risk events, the underground depth of the building was generally 5 meters.

There were many levels and elements to consider when building an underground doomsday shelter. From the perspective of a basic Level 1 primitive shelter, one could make use of a natural cave, equip it with basic shelter such as canvas or plastic sheets, store a small amount of canned food, bottled water, simple sleeping bags, blankets, and basic survival tools such as flashlights and matches. There might also be a small number of weapons. A Level 2 basic fallout shelter was to simply reinforce the cave or use wooden structures, add a small rainwater collection system, more food reserves, and basic medical supplies, set up a simple firewood stove for heating and cooking, establish basic sanitary facilities, and a small number of solar panels to provide limited power, and improve defense measures. The Level 3 medium fallout shelter was a semi-underground building reinforced with concrete. It had a small generator and battery system, a basic air filtering system, a medium-sized food and water storage, a small indoor planting area, a basic medical room (equipped with common drugs), simple communication equipment, reinforced metal doors, and surveillance cameras. The Level 4 Advanced Shelter was a well-designed underground complex with a long-term self-sufficient food production system, advanced water circulation and purification systems, stable and regenerative energy systems (such as small hydraulic power generation), a complete medical center (for surgery), educational facilities, entertainment areas, and an advanced defense system. Level 5 top-tier survival cities were large underground cities that could accommodate hundreds of people. They had a completely self-sufficient ecosystem, high-tech water and air circulation purification systems, a diverse energy system (including geothermal and nuclear energy), a comprehensive medical center (equipped with intensive care and research laboratories), large indoor farms and breeding facilities, manufacturing factories, a comprehensive education system, and the most advanced defense and monitoring systems. They also had the ability to conduct external exploration and resource extraction. American developer Larry Hall once transformed the underground launch well of the Atlas F launch vehicle into a luxurious "doomsday shelter" more than 50 meters underground. In short, the scale and level of construction of the underground doomsday shelter needed to be determined according to actual needs, resources, and technology.

I recommend " Primitive Construction ". Thank you, author. This was a great fantasy novel. The protagonist traveled through a primitive society. Others wanted to eat, but he wanted to build a city! The male protagonist, Wang An, was an ordinary person, while the female protagonist, Eagle, wanted to be a warrior. Construction was the main focus, and fighting was secondary. There were five elements tribes, totem power, and alchemy and weapon refinement. The world view was complex and rigorous. The protagonist relied on modern systems and vision to develop and build, and even used the five elements as a cheat to promote development. The author had a good grasp of the concept of time, but his view of primitive people was a little strange. " Devour the Starry Sky: My Comprehension Defies the Heavens!"
