  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 14 storing explosives and the like, which is the center of the storage warehouse 11, is installed on the ground 16. The material of the warehouse body 14 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 main body 14 and the surface above the ground 16 is covered with the sheet body 13, and the outer surface is covered with the soil layer 20. The sheet body 13 is made of a total rubber water-impervious sheet, and each of the flat portions 19a and 19b serving as end portions on the ground side includes a plurality of fixing members 17a such as anchor bolts as an example of fixing means, 17b is continuously fixed to the ground 16 in the longitudinal direction (vertical direction in FIG. 1). The width and strength of the flat portions 19a and 19b may be set according to the magnitude of the blast pressure.

  In addition, a sheet-like first drainage material 31 made of a nonwoven fabric is horizontally installed in the soil layer 20 above the warehouse body 14. By installing the first drainage material 31 in the soil layer 20, the water soaked into the soil layer 20 due to rain or the like moves through the first drainage material. Therefore, the amount of moisture in the soil layer 20 is reduced, so that the strength of the soil layer 20 is maintained. That is, the soil layer 20 is prevented from collapsing.

  Further, the static friction force applied to a part of the soil layer 20 applied to the horizontal surface of the outer surface of the first drainage material 31 is set to be larger than the static friction force applied to a part of the soil layer 20 applied to the horizontal surface of the outer surface of the sheet body 13. Has been. By setting in this way, a part of the soil layer 20 on the first drainage material 31 is less likely to collapse than a part of the soil layer 20 on the sheet body 13. Therefore, there is no possibility that the soil layer 20 will be carelessly collapsed by installing the first drainage material 31 in the soil layer 20.

  It should be noted that both ends in the longitudinal direction of the warehouse main body 14 may be configured to be covered with the sheet body 13 and the soil layer 20 as in the cross-sectional view of FIG. 2, but are closed by other structures incorporating a door structure. You may do it. In any case, the entire surface of the warehouse main body 14 in FIG. 2 is covered with the sheet 13 and the soil layer 20 in the side surface direction and the upper surface direction.

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

  When the explosives stored in the warehouse body 14 explode for some reason, the fragments are scattered around and the blast spreads. However, since the periphery of the warehouse main body 14 above the ground 16 is covered with the sheet body 13, debris and blast are surrounded by the sheet body 13. Since the sheet body 13 covers the outer surface of the warehouse main body 14 and the flat portions 19a and 19b are fixed to the ground 16, the sheet body 13 is not swung up by a blast or the like. As a result, in a state where the sheet body 13 is not damaged, the blast transmitted to the sheet body 13 surrounding the warehouse body 14 is not diffused to the outside, so that the safety of the surroundings is improved. The blast diffused in the direction of the ground 16 is absorbed by the ground 16 and does not affect the surroundings above the ground 16.

  In addition, since the outer surface of the sheet body 13 is covered with the soil layer 20, the soil layer 20 reliably prevents the sheet body 13 from being lifted by a blast transmitted by the explosion of the warehouse body 14. Therefore, the function of the sheet body 13 is reliably exhibited, and the reliability of the storage warehouse 11 is improved. The soil type and construction thickness of the soil layer 20 may be determined according to the influence on the sheet body 13 by the explosive force of explosives stored in the warehouse body 14.

  In addition, since the sheet body 13 has water shielding properties, rainwater or the like does not permeate into the inner side of the sheet body 13. Therefore, the effect which prevents the wetting of the explosives in the warehouse main body 14 can be expected. Further, since the scattering of small pieces at the time of explosion is prevented, the safety is further improved.

  FIG. 3 is a schematic sectional view of a storage warehouse according to the second embodiment of the present invention, corresponding to FIG. 2 according to the first embodiment, and FIG. 4 is an enlarged view of part A shown in FIG. FIG.

  With reference to these drawings, 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 11 according to this embodiment, the shape of the first drainage material 31 is greatly different. That is, the first drainage material 31 is inclined such that the end portions 35a and 35b side (left and right sides in FIG. 3) are inclined downward, and the end portions 35a and 35b are positioned in the vicinity of the outer end portion below the soil layer 20. Is formed. Further, a sheet-like total rubber-made water shielding material 33 is provided so as to be in contact with the inner surface of the first drainage material 31. The material of the water shielding material 33 may be any material having water shielding properties such as resin or metal.

  Since the end portions 35 a and 35 b of the first drainage material 31 are inclined downward, the water in the soil layer 20 that has penetrated due to rain or the like moves along the slope of the first drainage material 31. Therefore, the water in the soil layer 20 becomes easy to move, and the drainage in the soil layer 20 is improved.

  Further, since the end portions 35 a and 35 b of the first drainage material 31 are located near the outer end portion below the soil layer 20, the water in the soil layer 20 passes through the first drainage material 31 and the soil layer 20. It is guided to the vicinity of the outer end below. Therefore, the water in the soil layer 20 can be quickly discharged to the outside of the soil layer 20.

  Furthermore, since the water shielding material 33 is installed so as to be in contact with the inner surface of the first drainage material 31, the entry of water inward from the water shielding material 33 in the soil layer 20 is prevented. Therefore, the amount of water held by the portion of the soil layer 20 on the inner side of the water shielding material is always constant, and the strength of this portion is stabilized.

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

  With reference to these drawings, 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 11 according to this embodiment, the shapes of the sheet body 13 and the first drainage material 31 are greatly different. That is, the flat portions 19 a and 19 b of the sheet body 13 are formed so that the end portions thereof are positioned in the vicinity of the outer end portion below the soil layer 20. And the 1st drainage material 31 is installed so that the outer surface of the sheet | seat body 13 may be contact | connected. Therefore, since the end portions 35a and 35b of the first drainage material 31 are located in the vicinity of the outer end portion below the soil layer 20, the water in the soil layer 20 is drained as in the second embodiment. It becomes possible to quickly discharge to the outside of the soil layer 20.

  Further, since the drainage material 31 is installed in contact with the outer surface of the sheet body 13, the installation position of the first drainage material 31 is stabilized. Therefore, the installation work of the 1st drainage material 31 at the time of construction of the storage warehouse 11 becomes efficient.

  FIG. 6 is a schematic sectional view of a storage warehouse according to the fourth embodiment of the present invention, and corresponds to FIG. 5 according to the third embodiment.

  Referring to the figure, a warehouse main body 14 that stores explosives and the like that is the center of a storage warehouse 11 is installed on a ground 16. The outer surface of the warehouse main body 14 and the surface above the ground 16 is covered with the first soil layer 21, and the outer surface is covered with the sheet body 13. And the sheet-like drainage material 31 is installed so that the outer surface of the sheet | seat body 13 may be contact | connected. Further, the outer surface of the sheet body 13 is covered with a second soil layer 27.

  Except for the structure of the drainage material 31 to be described later, the materials and strengths of each structure constituting the storage warehouse, that is, the warehouse main body 14, the sheet body 13, and each soil layer are the same as those in the third embodiment. is there. Therefore, the storage warehouse 11 according to this embodiment exhibits the same effect as the storage warehouse of the third embodiment.

  Further, in the storage warehouse 11 according to this embodiment, since the area above the ground 16 of the warehouse body 14 is covered with the first soil layer 21, debris and blasts are generated in the first soil during the above-described explosion. It is transmitted to the sheet body 13 while being absorbed by the layer 21. Therefore, the impact on the sheet body 13 is reduced. As a result, the strength of the sheet body 13 can be set low.

  Here, the structure of the drainage material 31 according to this embodiment will be described.

  FIG. 7 is an enlarged view of a portion B shown in FIG.

  With reference to the drawing, the drainage material 31 is disposed on the outer surface of the sheet-like body 45, the first nonwoven fabric 41 made of sheet-like polypropylene, the mesh-like body 45 made of polyethylene, and the outer surface of the mesh-like body 45. It is comprised from the 2nd nonwoven fabric which consists of the arrange | positioned sheet-like polypropylene.

  About the drainage material of such a structure, it describes in Unexamined-Japanese-Patent No. 10-328635, for example. Since the mesh-like body 45 is formed with a plurality of protrusions and strip-shaped water passage grooves, there is a continuous gap between the first nonwoven fabric 41 and the second nonwoven fabric 42. Therefore, the water that has permeated into the soil layer through the gap and the water channel can be quickly discharged.

  FIG. 8 is a schematic sectional view of a storage warehouse according to the fifth embodiment of the present invention, corresponding to FIG. 6 according to the fourth embodiment.

  With reference to these drawings, since the basic configuration is the same as that of the storage warehouse of the fourth embodiment, the difference will be mainly described here.

  In the storage warehouse 11 according to this embodiment, a sheet-like shape made of a non-woven fabric is provided above each of the first drainage materials 31 and on both outer end sides in the second soil layer 27. Second drainage materials 51a and 51b are further provided. Accordingly, the water contained in the second soil layer 27 that has penetrated due to rain or the like moves also through the second drainage materials 51 a and 51 b in addition to the first drainage material 31. That is, since it drains with the 1st drainage material 31 and the 2nd drainage material 51a, 51b, the drainage property in the 2nd soil layer 27 further improves.

  FIG. 9 is a schematic cross-sectional view of a storage warehouse according to the sixth embodiment of the present invention, which corresponds to FIG. 2 according to the first embodiment, and FIG. 10 is an enlarged view of part C shown in FIG. FIG.

  With reference to these drawings, 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 11 according to this embodiment is largely different in that it does not have drainage material. Further, the shape of the sheet 13 is greatly different, and details and effects of this shape will be described below.

  Here, with reference to FIG. 10, a plurality of protrusions 23 are formed on the outer surface of the sheet body 13. That is, it is formed so that the degree of unevenness on the outer surface of the sheet body 13 is larger than the inner surface. Accordingly, the friction coefficient of the outer surface of the sheet body 13 is larger than the friction coefficient of the inner surface. Since the sheet body 13 is formed in this way, the frictional resistance between the soil layer 20 and the sheet body 13 is increased, and it becomes difficult to slip. Therefore, collapse of the soil layer 20 is prevented.

  FIG. 11 is a schematic cross-sectional view of a storage warehouse according to the seventh embodiment of the present invention, corresponding to FIG. 6 according to the fourth embodiment, and FIG. 12 is an enlarged view of portion D shown in FIG. FIG.
