Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a radioactive sielter, and more specifically to one that has been improved so that it can collect groundwater from the surrounding soil in which it is embedded.

``Conventional Example'' When radioactive fallout suddenly increases due to a nuclear test or an accident at a nuclear power plant, it is necessary to minimize the amount of radiation that the human body receives. For this purpose, radioactive siertas are set up underground where people can live for several months.

In conventional radioactive shelters, water for cooking and other domestic purposes is stored in a water tank provided within or near the main body, and is configured to prevent groundwater from penetrating into the main body. Of course, when the water tank is provided outside the main body, the water tank is configured to prevent water leakage to the outside. To the water tank,
To avoid the use of radioactively contaminated water, water is stored in advance from a separate above-ground water supply facility, and an indoor water supply system is installed to supply water from the water tank to indoor faucets.

Also, in case a so-called radioactive cloud containing radioactive dust etc. thickly covers the ground and the ground surface temperature drops to, for example, several tens of degrees below zero, the temperature inside the radioactive shelter is maintained at approximately a predetermined temperature. Air conditioning equipment may also be provided for this purpose. That is, for example, a private power generator and an electric heater and/or air conditioner operated with the electric power obtained from the private power generator are provided.

``The problem that the invention aims to solve'' However, when it comes to domestic water, once it escapes into a radioactive shelter, the water supply facility must be operated until the radiation level on the ground has decreased below a predetermined value. Can not do it. Therefore, a problem arises in that the amount of time a person can spend inside the radioactive shelter is limited by the capacity of the water tank.

In addition, in order to perform air conditioning, it is necessary to stockpile a large amount of fuel to handle the large load in order to operate the private power generation equipment, and the amount of stockpiled fuel limits the period of time that can be spent in the radiation shelter. There are other problems.

This idea was devised under these circumstances, and its purpose is to ensure that the amount of time a person can spend inside a radioactive sielter is not limited by the amount of water stored in the water tank. In addition, if air conditioning equipment is installed, the heat load on the air conditioning equipment should be minimized to reduce the load on the private power generator, so that air conditioning can be performed for a longer period of time with less stored fuel. is also considered to be the purpose of this idea.

"Means for Solving the Problem" In order to achieve the above-mentioned purpose, this invention places the main body of the radioactive shelter on a solid foundation with a larger planar area, and runs along the outside of the side wall of the main body. Then, a water collection block was installed on the top of the above-mentioned foundation.
A water collection chamber is formed inside the block, and
A technical measure is taken in which the block is provided with a water hole that communicates and connects the outside of the block with the water collection chamber.

With this configuration, groundwater can be collected into the water collection chamber within the block through the water passage hole. The groundwater collected here is naturally filtered before reaching this point from the ground surface, and by pumping up this groundwater with an indoor water supply system, it can be used as drinking water, depending on the amount of water stored in the water tank. There will no longer be any restrictions on how long you can live in a radioactive sierta.

In addition, groundwater is hotter than the ground surface temperature, which is extremely low, so the heat load on the air conditioner can be reduced by pre-warming the outside air heated by the air conditioner with groundwater, or by having the air conditioner absorb heat from this groundwater. . Therefore, the load on the private power generator is reduced, and air conditioning can be performed for a longer period of time with less stored fuel. As a result, it is possible to relax the restrictions on the period of life given by the amount of fuel reserves and extend the period of life within the radioactive shelter.

"Example" This invention will be described in detail below with reference to the drawings.

These blocks 4... are made of concrete as shown in Figure 3, and each has a water collection chamber 4 inside.
It has 1... This water collection chamber 41 is filled with a filler 5 such as gravel, stones, gravel, and sand for filtering water. The upper surface of the uppermost block 4 is covered with a lid 6 as required. Further, the blocks 4 and the lid 6 are provided with water holes 42 that communicate the inside and outside of the blocks 4. Therefore, the groundwater contained in the ground around the radioactive shelter 1 flows into the water collection chambers 41 in the blocks 4 through the water passage holes 42.
It can flow in through. Water collection chamber 4 of each block 4...

Although the weight of this block 4 is reduced by providing the water collection chamber 41, the weight of the filler 5 such as gravel packed therein and the weight of the groundwater coming in from the water passage hole 42... This will compensate for the reduced weight, including the weight of block 4, and will prevent radioactive shelter 1 from surfacing caused by earth pressure and groundwater. Become.
