It is a schematic sectional drawing of the storage warehouse by the 8th Embodiment of this invention.

  FIG. 1 is a plan view showing the appearance of a storage warehouse according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line II-II shown in FIG.

  With reference to these drawings, a warehouse main body 19 that stores explosives and the like, which is the center of the storage warehouse 11, is installed on an installation surface 7 that is the ground. The material of the warehouse body 19 is not limited, but may be any structure as long as it can hold a structure or the like installed on the outer surface as described below.

  The outer surface of the warehouse body 19 and above the installation surface 7 is covered with the first soil layer 31, and the outer surface is covered with the first sheet body 21. The first sheet body 21 is made of an all-rubber water-impervious sheet. The first sheet body 21 is a barrier that prevents rainwater and the like from entering the warehouse body 19 and the first soil layer 31 located on the inner side of the first sheet body 21. Has water function.

  The outer surface of the first sheet body 21 is covered with the second soil layer 32, and the outer surface is covered with the second sheet body 22. Further, the outer surface of the second sheet body 22 is covered with a third soil layer 33. A reinforcing sheet made of woven fabric is used for the second sheet body 22, and the mesh interval and the fiber strength are determined so as to suppress the scattering of the second soil layer 32 during the explosion of the warehouse body 19. That is, the second sheet body 22 has an explosion suppression function. In addition, the storage warehouse 11 which has the explosion suppression function suitable for various conditions can be easily constructed by changing the fiber strength of the 2nd sheet | seat body 22. FIG.

  Further, each of the flat portions 41a and 41b serving as the end portions on the installation surface 7 side of the second sheet body 22 is longitudinally (see FIG. 2 is fixed to the installation surface 7 continuously. What is necessary is just to set the width | variety and intensity | strength of flat part 41a, 41b, and the installation space | interval of fixing member 42a, 42b with the magnitude | size of a blast pressure.

  Next, safety in the storage warehouse 11 will be described.

  When the explosives stored in the warehouse body 19 explode for some reason, the fragments are scattered around and the blast spreads. However, since the periphery above the installation surface 7 of the warehouse body 19 is covered with the second sheet body 22, debris and blast are suppressed by the second sheet body 22. Moreover, since the 2nd sheet | seat body 22 covers the outer side of the warehouse main body 19, and the flat parts 41a and 41b are being fixed to the installation surface 7, the 2nd sheet | seat body 22 does not roll up by a blast. As a result, in a state where the second sheet body 22 is not damaged, diffusion of the blast transmitted to the second sheet body 22 surrounding the warehouse main body 19 to the outside is suppressed, and thus the surrounding safety is improved. The blast diffused in the direction of the installation surface 7 is absorbed by the ground and does not affect the surroundings above the installation surface 7.

  In addition, although the 1st sheet | seat body 21 is also installed so that the warehouse main body 19 may be enclosed, the 1st sheet | seat body 21 plays the role of a water-blocking function to the last. Therefore, it is not necessary to have a function of suppressing the explosion of the warehouse body 19 and may have a strength that may spread to the outside due to a blast.

  Thus, since the 1st sheet | seat body 21 has water-imperviousness, rain water etc. do not osmose | permeate the warehouse main body 19 and the 1st soil layer 31 which are located in the inner side of the 1st sheet | seat body 21. FIG. Accordingly, wetting of the explosives in the warehouse body 19 is prevented. Furthermore, the moisture content in the first soil layer 31 is maintained. That is, since the viscosity of the first soil layer 31 is maintained, the collapse of the first soil layer 31 is prevented.

  Thus, in the storage warehouse 11, the first sheet body 21 and the second sheet body 22 share the water shielding function and the explosion suppression function. Therefore, for example, a more efficient arrangement is possible compared to a storage warehouse that uses a single sheet body in which a water shielding function and an explosion suppression function are integrated, such as a woven cloth embedded in a rubber sheet. . In other words, since the first sheet body 21 and the second sheet body 22 may be installed in the range where each function is required, the installation range of the first sheet body 21 and the second sheet body 22 is not wasted.

  Further, by using two sheet bodies of the first sheet body 21 and the second sheet body 22, the number of soil layers of the storage warehouse 11 is increased as compared with the case of using one sheet body. . Therefore, since the soil layers are not integrated and become independent, the collapse of the entire soil layer is prevented. That is, the strength of the entire soil layer of the storage warehouse 11 is improved.

  In addition, since the outer surface of the second sheet body 22 is covered with the third soil layer 33, the installation state of the second sheet body 22 is stabilized, and the second sheet is generated by a blast transmitted by the explosion of the warehouse body 19. The lifting of the body 22 is surely prevented by the third soil layer 33. Therefore, the explosion suppression function of the second sheet body 22 is further improved, and the reliability of the storage warehouse 11 is improved.

  In addition, the kind of soil and construction thickness of the 1st soil layer 31, the 2nd soil layer 32, and the 3rd soil layer 33 depend on the 2nd sheet | seat body 22 by the explosive force of the explosives stored in the warehouse main body 19. What is necessary is just to determine to various structures according to an influence etc.

  Moreover, such a storage warehouse 11 can be similarly applied to the storage warehouse 11 installed underground as shown by a two-dot chain line in FIG. Below, it demonstrates centering on a different point from the storage warehouse 11 installed on the ground mentioned above.

  With reference to FIG. 2, the warehouse body 19 is installed on an installation surface 7 that is an excavation bottom surface formed by excavating the ground 5. The outer surface of the second sheet body 22 is covered with a third soil layer 33 whose upper surface is aligned with the ground 5. That is, the remainder of the excavation portion including the excavation side surfaces 44 a and 44 b is filled with the third soil layer 33. Such a third soil layer 33 may be used as the first fixing means of the second sheet body 22, and the flat portions 41 a and 41 b of the second sheet body 22 may be fixed on the installation surface 7. In that case, the fixing members 42a and 42b such as the anchor bolts described above may be omitted. Alternatively, the third soil layer 33 and the fixing members 42a and 42b may be used together as the first fixing means.

  In addition, it cannot be overemphasized that the effect in the storage warehouse 11 installed in such a basement is the same as that of the storage warehouse 11 installed on the ground mentioned above.

  FIG. 3 is a schematic sectional view of a storage warehouse according to the second embodiment of the present invention, and corresponds to FIG. 2 of the first embodiment.

  In the storage warehouse 12 according to this embodiment, the structure on the outer surface side of the second sheet 22 is greatly different. That is, the storage warehouse 12 does not include the third soil layer 33 that covers the outer surface of the second sheet body 22 shown in FIG. 2, and the outer surface of the second sheet body 22 is exposed.

  In such a storage warehouse 12, it is not necessary to install the third soil layer 33 shown in FIG. 2, so that the construction work can be saved and the installation process of the storage warehouse 12 can be further simplified. .

  In the storage warehouse 12 as well as the storage warehouse according to the first embodiment, as shown by the two-dot chain line in the figure, the same applies even when the storage warehouse 12 is installed underground. it can. In that case, the 3rd earth layers 33a and 33b are formed so that the space between each of the side part of the 2nd sheet body 22 and each of excavation side surfaces 44a and 44b may be filled up. Since the third soil layers 33 a and 33 b are formed on the flat portions 41 a and 41 b of the second sheet body 22, there is an effect of preventing the second sheet body 22 from rising. Furthermore, the third soil layers 33a and 33b can be used as the first fixing means to the installation surface 7 of the second sheet body 22, and in this case, the fixing members 42a and 42b may be omitted.

  FIG. 4 is a schematic sectional view of a storage warehouse according to the third embodiment of the present invention, and corresponds to FIG. 2 of the first embodiment.

  The storage warehouse 13 according to this embodiment is the same as the storage warehouse according to the first embodiment except for the installation position and the installation shape of the first sheet body 21. That is, the outer surface of the warehouse main body 19 is directly covered with the first sheet body 21 without using a soil layer.

  In such a storage warehouse 13, the warehouse body 19 is directly shielded by the first sheet body 21. Therefore, the amount of the first sheet body 21 used is smaller than that of the storage warehouse according to the first embodiment. Can be suppressed. That is, the storage warehouse 13 is advantageous in terms of cost.

  In addition, since the structure of the outer side from the 1st sheet | seat body 21 is the same as that by 1st Embodiment, it cannot be overemphasized that the same effect is exhibited.

  FIG. 5 is a schematic sectional view of a storage warehouse according to the fourth embodiment of the present invention, and corresponds to FIG. 2 of the first embodiment.

  The storage warehouse 14 according to this embodiment is the same as the storage warehouse according to the first embodiment except for the installation shape of the first sheet body 21 in particular. That is, the outer surface of the warehouse body 19 is covered with the first soil layer 31, and the first sheet body 21 is planar so as to cover at least the range in the plan view of the warehouse body 19 on the upper surface 37 of the first soil layer 31. Is installed. Further, the upper surface of the first sheet body 21 is covered with the second soil layer 32, and the outer surfaces of the first soil layer 31 and the second soil layer 32 are covered with the second sheet body 22.

  In such a storage warehouse 14, rainwater from above is directed to the portion of the first soil layer 31 located below the first sheet body 21 and the warehouse body 19 by the first sheet body 21 having a water shielding function. Intrusion is prevented. Therefore, since the moisture content of the first soil layer 31 is maintained, the collapse of the first soil layer 31 is prevented. Further, the explosives in the warehouse body 19 are prevented from being wetted.

  It should be noted that, similarly to the storage warehouse according to the first embodiment, the present invention is not limited to the case where it is installed on the ground as shown in the figure, and the storage warehouse 14 can be similarly applied even when it is installed underground.

  FIG. 6 is a schematic sectional view of a storage warehouse according to the fifth embodiment of the present invention, and corresponds to FIG. 2 of the first embodiment.

  In the storage warehouse 15 according to this embodiment, the storage warehouse according to the first embodiment is provided except for the portion not provided with the first sheet body having the water shielding function of the storage warehouse according to the first embodiment. Is the same. That is, the outer surface of the warehouse main body 19 is waterproofed as shown by the broken line. And the outer surface of the warehouse main body 19 is covered with the 1st soil layer 31, and the outer surface of the 1st soil layer 31 is covered with the sheet body 23 same as the 2nd sheet body 22 shown in FIG. That is, the sheet body 23 is composed of a reinforcing sheet made of woven fabric and has an explosion suppressing function.

  In such a storage warehouse 15, the outer surface of the warehouse body 19 is waterproofed, so that the explosives in the warehouse body 19 are prevented from being wetted. Therefore, since it is not necessary to install a sheet body having water shielding properties, the storage warehouse 15 is advantageous in terms of cost.

  Note that, similarly to the storage warehouse according to the first embodiment, the present invention is not limited to the case where the storage warehouse 15 is installed on the ground as shown in the figure, and the storage warehouse 15 can be similarly applied even when it is installed underground.

  FIG. 7 is a schematic sectional view of a storage warehouse according to the sixth embodiment of the present invention, and corresponds to FIG. 2 of the first embodiment.

  With reference to the drawing, the basic configuration is the same as that of the storage warehouse of the first embodiment, and therefore, the difference will be mainly described here.

  In the storage warehouse 16 according to this embodiment, the positional relationship between the first sheet body 24 having an explosion suppressing function and the second sheet body 25 having a water shielding function is greatly different. That is, the outer surface of the first soil layer 31 is covered with the first sheet body 24 having an explosion suppressing function. Further, the outer surface of the first sheet body 24 is covered with the second soil layer 32, and the outer surface of the second soil layer 32 is covered with the second sheet body 25 having a water shielding function.

  In such a storage warehouse 16, like the storage warehouse according to the first embodiment, the first sheet body 24 and the second sheet body 25 share an explosion suppression function and a water shielding function. Accordingly, the same effect can be obtained even when the positions of the first sheet body 24 and the second sheet body 25 are switched with respect to the positional relationship of the sheet bodies in the storage warehouse according to the first embodiment. Play.

  It should be noted that, similarly to the storage warehouse according to the first embodiment, the present invention is not limited to the case where it is installed on the ground shown in the figure, and the storage warehouse 16 can be similarly applied even when it is installed underground.

  With reference to the drawing, the basic configuration is the same as that of the storage warehouse of the first embodiment, and therefore, the difference will be mainly described here.

  The storage warehouse 17 according to this embodiment further includes a third sheet body 27 having an explosion suppression function. That is, the outer surface of the third soil layer 33 is covered with the third sheet body 27 having the same function as the second sheet body 22, and the outer surface of the third sheet body 27 is covered with the fourth soil layer 34. Each of the flat portions 46a and 46b serving as the end portions on the installation surface 7 side of the third sheet body 27 has a plurality of fixing members 47a such as anchor bolts, which are second fixing means, like the second sheet body 22.
