Every now and then we herald the end of the world.
And he does not come and did not come.
However, in case of possible natural disasters or nuclear attack better prepare yourself. And the first and most important step in this regard would be the construction of an underground bunker.
And then you can select the desired option of the two.
Either it will be a shallow tank of wood that can protect you from the storm, or it will be a bunker made of concrete and metal.
This can and survive a nuclear bombing.
The simplest version of the bunker? This hole, at the bottom of which is placed a stone or a tree. The walls of the pit are covered by the tree to prevent a possible drift of the earth. And the roof of the bunker is this: pit covered with wooden planks, as well as multiple layers of polyethylene. After that the roof need to fill up at least dvadtsatisantimetrovym layer of earth. In addition, the need to equip the entrance (in combination also ventilation) and toilet.
To construct the entrance, you can take the tube to the desireddiameter installed therein germodveryu. To make the toilet, you should dig another pit for example pits for bunker and then between her and bin do pass. Do not forget about the water supply, which adapts to the barrel without a bottom, rooted to the spot so that it accumulated under ground water (if any). In case you have to live in a bunker for a long time, you need to stock up on water and air filters, as well as to establish an electric generator.
The bunker of concrete and iron is much more reliable,but also more complex in construction. It is to be positioned at 2 to 10 meters depth. The base of the hopper is covered with half a meter of sand. Then, a layer of concrete falls on him. Then pour the concrete should be reinforcing cage, which will form the base of the hopper when dry.
Next construct a framework of reinforcement and for roomswalls and iron formwork. The main condition here is that the design of the ceiling should not extend beyond the hole. Between the earth and the outer wall of the silo should be set to fill sand and waterproofing.
Entrance to the bunker is better to make a smallrooms made of reinforced concrete, surrounded by foam concrete blocks. The very passage into the hopper to make the best of the sewer rings. At the entrance to install itself in germodver bunker room. The hopper must be at least two ventilation ducts to be positioned at a distance of at least 3 meters hopper. These mines will also play the role of emergency exits or exits in case of any emergencies. Do not forget to install an electric generator in the room bunker, set filters for air and water as well as cleaning toilets (biotoilets).
