  Hereinafter, in describing the configuration of the bulletproof levee structure 1 with reference to FIGS. 1 to 7, as shown in FIG. 1, the direction facing the target 9 set upright when viewed from the shooter is the present embodiment. Let the front F in the form.

  An enclosure 2 configured in a cubic shape that opens up and down, a bullet capturing material 3 filled in a space S surrounded by the enclosure 2, and a bottom plate 4 attached to the enclosure 2 to cover the bottom end opening of the enclosure 2 And a top plate 5 attached to the enclosure 2 so as to cover the upper end opening of the enclosure 2 to form a bulletproof levee, and a plurality of such bulletproof embankments (five in the illustrated embodiment) are continuously provided. Thus, a bulletproof levee 1 is constructed. Furthermore, for some of the plurality of bulletproof levees that constitute the bulletproof levee structure 1, a rigid plate 6 is installed along the enclosure 2 thereof.

  Each enclosure 2 is configured by combining four plate-like members made of an elastic material so as to form a letter “ロ” in plan view. This configuration will be described in detail later.

  The projectile capture material 3 can capture projectiles entering the space S surrounded by the enclosure 2 so as not to bounce or further advance, and after use, for example, by a simple method such as sieving. , The bullet and the bullet catching material 3 can be easily separated.

  As a typical example of what is suitable as the bullet capturing material 3, there are a rubber chip and a stoneless soil. With regard to rubber chips, for example, by making them into particles of about 3 mm in diameter, it is less likely that the projectile will get stuck in the particles of the rubber chip while ensuring the function of capturing the projectile, and the projectiles are screened after use. It will be easier to separate them. Stoneless soil consists of fine-grained soil remaining after removing stones that may cause jumps with a sieve, and has a function as a good bullet-capturing material 3.

  Such granular rubber chips or stone-free soil may be directly filled in the space S surrounded by the enclosures 2, or a certain amount of rubber chips or stone-free soil may be packed in a sandbag to form a sandbag, The sandbag thus produced may be filled in the space S.

  With regard to the number and layout of the enclosures 2, those suitable for achieving a good ballistic-resistant effect for the target lower device 9a are selected, and by varying the number and layout of the enclosures 2, various sizes and shapes can be obtained. Can be configured.

  1 to 5 show one configuration example of the bulletproof levee 1. The bulletproof levee 1 shown here comprises five bulletproof levees. The enclosures 2 of each of the bulletproof levees are arranged such that the aforementioned four plate-like members which are the constituent members form the front, rear, left, and right side walls, with the space S enclosed by the enclosure 2 opening upward and downward. .

  At the back of the target lower device 9a, three bulletproof levees are connected in a row in the left-right direction. In this row, the bulletproof enclosure 2 (designated as enclosure 2A) located at the left end is the left rear of target lower device 9a, and the bulletproof enclosure 2 (designated as enclosure 2C) placed at the right end is the target Enclosures 2 (referred to as an enclosure 2B) of the bulletproof levees disposed at the right rear of and in the middle of the lower apparatus 9a are respectively disposed immediately after the target lower apparatus 9a.

  The remaining two enclosures 2 are distributed on the left and right sides of the target lower device 9a. The target lower device 9a has a left side bulletproof enclosure 2 (referred to as an enclosure 2D) and a left lower rear target bulletproof enclosure 2A of the target lower device 9a connected in a row in the front-rear direction. An enclosure 2 (referred to as an enclosure 2E) on the right side of the bulletproof embankment and an enclosure 2C on the right rear of the target lower device 9a are connected in a row in the front-rear direction.

  Of the five enclosures 2 connected in this way, a space surrounded by the middle enclosure 2B and the two front right and left enclosures 2C and 2D among the three rear enclosures 2 is secured, and in this space The target lower device 9a will be arranged.

  Adjacent enclosure 2 and enclosure 2 are fastened using fasteners, such as a screw, and a plurality of bulletproof levees are fixed by this, and one bulletproof embankment structure 1 is constituted.

  On the front end face of the bulletproof enclosure 2B immediately after the target lower apparatus 9a, the right end face of the bulletproof enclosure 2D on the left side of the target lower apparatus 9a, and the left end face of the bulletproof embankment 2E on the right of the target lower apparatus 9a Along the length, a rigid plate 6 made of steel or the like is disposed.

  Even if the projectile penetrates all the projectiles 3 in both the enclosure 2 and the enclosure 2 and reaches the target lower device 9a, the rigid plate 6 shields the projectiles so that the projectiles It does not reach the device 9a. The attachment structure and the like of the rigid plate 6 to the enclosure 2 will be described in detail later.

  Furthermore, each of the bulletproof embankments in the illustrated bulletproof levee structure 1 includes a bottom plate 4 laid on the ground, a floor surface, or the like. That is, the whole of the bulletproof levee 1 is provided with the same number of bottom plates 4 as the enclosure 2. By installing the bottom end of each enclosure 2 on each bottom plate 4, the lower end opening of the space S surrounded by the enclosure 2 is closed, and the leakage of the bullet capture material 3 filled in the space S is prevented.

  The bottom plate 4 is fastened to the enclosure 2 using a fastener such as a screw. A container-like unit composed of the enclosure 2 and the bottom plate 4 thus arranged is disposed at a desired position in the installation stroke of the bulletproof levee 1, and the bullet capturing material 3 is placed in the space S surrounded by the enclosure 2 in this unit. Fill.

  After that, the top plate 5 is attached to the upper end of the enclosure 2 via a fastener such as a screw to prevent the bullet capturing material 3 from being surrounded by wind or a bullet and the like and scattered to the outside of the enclosure 2. Close up. Thus, one bulletproof embankment comprising the enclosure 2, the bullet catching member 3, the bottom plate 4 and the top plate 5 is completed.

  FIG. 8 is a view showing a base plate-like member for the bottom plate and the top plate in the bulletproof embankment according to the first embodiment, wherein (a) is a main surface seen from a direction perpendicular to the main surface FIG. 9B is a view of the side end as viewed from the direction along the main surface, and FIG. 9 shows the first fitting plate member for enclosure configuration in the bulletproof embankment according to the first embodiment. It is a figure which shows, and is a figure which looked at the principal surface in the direction of a look of a right angle to the principal surface, and (b) is a figure which looked at the concavo-convex side in the direction of a principal line Fig. 10 is a view showing a second fitting plate-like member for enclosure configuration according to the first embodiment, wherein (a) is a view of the main surface viewed in a direction perpendicular to the main surface; (B) is the figure which looked at the uneven | corrugated shaped side part in the gaze in the direction which follows a main surface.

  In addition to FIGS. 1 to 7, referring to FIG. 8, one basic plate-like member 10 shown in FIG. 8 is used as it is as each bottom plate 4 and each top plate 5. 9 and 10, enclosure 2 is configured by combining a pair of first fitting plate members 20 shown in FIG. 9 and a pair of second fitting plate members 30 shown in FIG. Ru. The basic plate-like member 10, the first fitting plate-like member 20 and the second fitting plate-like member 30 are formed by molding the same elastic material into respective shapes.

  The first plate member 20 and the second plate member 30 are installed as the enclosure 2 of the bulletproof embankment, and after the bullet penetrates, the diameter of the hole as the bullet penetration mark shrinks, and most preferably, it shrinks and closes. Is required. The same function is required for the basic plate member 10 used as the bottom plate 4 and the top plate 5. The elastic materials of these plate-like members 10, 20, and 30 need to have elasticity to perform such a function.

  A typical example of one suitable as the elastic material is rubber. Here, it is also conceivable to solidify and shape the same rubber material as the rubber chip used as the bullet capture material 3 to form the plate-like members 10, 20, 30. By constructing the plate-like members 10, 20 and 30 in this manner, the enclosure 2, the bottom plate 4 and the top plate 5 can be constructed of the same material as the bullet capturing material 3 and the bullets are shot into the bulletproof levee 1 It is possible to configure the anti-ballistic levee structure 1 in which the ballistics are unlikely to change in the process of being released and unlikely to cause an unexpected bounce.

  The basic plate member 10 is a hexahedron having a pair of square main surfaces 11 opposed to each other, and four side surfaces 12 interposed between the main surfaces 11 and 11. The length of one side of the square main surface 11 is L, and the width of the four side surfaces 12 between the main surfaces 11 and 11, that is, the thickness of the basic plate member 10 is W1.

  The square shape of the main surface 11 of the basic plate member 10, where one side length is L, is a reference for forming the first fitting plate member 20 and the second fitting plate member 30. That is, the main surface 11 of the basic plate member 10 is the upper surface of the bottom plate 4 in contact with the lower end surface of the enclosure 2 and the lower surface of the top plate 5 in contact with the upper end surface of the enclosure 2. Assuming that each enclosure 2 is disposed as shown in FIG. 1, and the end faces of the bottom plate 4 and the top plate 5 in the front, rear, left, and right are arranged flush with the front, rear, left, and right ends of the enclosure 2, the basic plate shape One side length L of the main surface 11 of the member 10 defines the horizontal length of the front, rear, left, and right outer end faces of the enclosure 2.

  Therefore, assuming that the first fitting plate member 20 and the second fitting plate member 30 are arranged in a vertical shape as the enclosure 2 of the bulletproof levee structure 1, the maximum length in the horizontal direction of each of the first fitting plate member 20 and the second fitting plate member 30 is Like the square one side length of the main surface 11 of the basic plate member 10, it is L.

  The following description of the first fitting plate member 20 and the second fitting plate member 30 is similarly assumed to be vertically arranged as the enclosure 2 of the bulletproof levee.

  The length (height) of the first fitting plate member 20 and the second fitting plate member 30 in the vertical direction is T. This height T is the height of the enclosure 2 as it is, and is a dimension determined by how to set the height of the enclosure 2. Although it is not necessary to make the height T equal to the maximum length L in the horizontal direction of the first fitting plate member 20 and the second fitting plate member 30, standardization of the plate members 10, 20, 30 is It is preferable to make the same (T = L) in terms of the purpose.

  Further, the thickness of the first fitting plate member 20 and the second fitting plate member 30 is W. The thickness W is the thickness of the enclosure 2 as it is, and is a dimension determined depending on how the thickness of the enclosure 2 is set. Although it is not necessary to make this thickness W the same as thickness W1 of basic plate-like member 10 as bottom plate 4 and top plate 5, they are made the same in that standardization of plate-like members 10, 20 and 30 is achieved. (W = W1) is preferred.

  The first fitting plate member 20 has a pair of opposed major surfaces 21, and the second fitting plate member 30 has a pair of opposed major surfaces 31. The main surfaces 21 and 31 are disposed as an inner peripheral surface of the enclosure 2 facing the space S and an outer peripheral surface of the enclosure 2 opposed thereto. A horizontal direction (direction perpendicular to the main surfaces 21 and 31) between both main surfaces 21 and 21 of each first fitting plate member 20 and between both main surfaces 31 and 31 of each second fitting plate member 30 Hereinafter, this distance is referred to as “thickness direction”, and the distance is the above-mentioned thickness W.

  The two side ends of the first fitting plate member 20 are respectively in a concavo-convex shape having notches 23 in the upper and lower two stages, and the two side ends of the second fitting plate member 30 are notches in the upper, middle, and lower three stages, respectively. It is uneven with 33. When the first fitting plate member 20 and the second fitting plate member 30 are aligned with the heights of the upper end and the lower end of the two, the notch 23 of the first fitting plate member 20 and the second fitting plate member The 30 notches 33 are arranged alternately in the vertical direction.

  If these notches 23 and 33 do not exist, each of the main surfaces 21 and 31 is a right quadrilateral whose upper side and lower side have a length L and both sides in the vertical direction have a length T. Furthermore, when T = L, the side length is a square of L.

  In other words, the two side ends of the first fitting plate member 20 each have the upper, middle, and lower three-tiered convex portions 24, and between the upper-tiered convex portion 24 and the middle-tiered convex portion 24 is the upper tier The notch 23 in the lower stage is a notch 23 in the lower stage between the convex section 24 in the middle stage and the convex section 24 in the lower stage. Further, both side end portions of the second fitting plate member 30 each have a convex portion 34 in upper and lower two stages, and the upper side of the convex portion 34 in the upper stage is a notch 33 in the upper stage. A notch 33 in the middle step is between the lower protrusion 34 and the lower step 34 is a lower notch 33.

  The width in the thickness direction of the notches 23 and 33 is W, and the horizontal depth of the notches 23 and 33 in the direction along the main surfaces 21 and 31 is also W. Therefore, the shape of all the notches 23 and 33 has a square-shaped horizontal cross section with one side length W, and has a vertical length T / 5 (five divisions of T). It has become. That is, the side length in the horizontal direction is W, and the side length in the vertical direction is T / 5 (T = (T = In the case of L, it is a rectangle which is L / 5). And the shape of each convex part 24 * 34 also corresponds with the shape of these each notch 23 * 33.

  A distance in the horizontal direction between the tips of the two convex portions 24 formed oppositely on both sides of the first fitting plate member 20, and formed oppositely on both sides of the second fitting plate member 30 The horizontal distance between the tips of the both convex portions 34 is the maximum horizontal length L of the first fitting plate members 20 and the second fitting plate members 30.

  The first fitting plate-shaped member 20 has the upper convex portion 24 formed on both sides at the upper end of the main surface 21 and the lower convex portion 24 formed on both sides at the lower end of the main surface 21. The upper end face 22 and the lower end face 22 of the first fitting plate member 20, which become the upper end face and the lower end face, are formed in a rectangular shape whose side length in the thickness direction is W and side length in the direction along the main surface 21 is L. ing.

  On the other hand, the distance in the horizontal direction between the back ends of the notches 23 formed oppositely on both sides of the first fitting plate member 20 and on both sides of the second fitting plate member 30 The distance in the horizontal direction between the deep ends of the notches 33, 33 to be formed is the thickness W from the maximum horizontal length L of each first fitting plate member 20 and each second fitting plate member 30. It becomes the length (L-2W) which reduced 2 times of.

  The second fitting plate-shaped member 30 has the upper end notch 33 formed on both sides at the upper end of the main surface 31 and the lower end notch 33 formed on both sides at the lower end of the main surface 31. The upper end face 32 and the lower end face 32 of the second fitting plate member 30 serving as the end face and the lower end face have a rectangular shape whose side length in the thickness direction is W and side length in the direction along the main surface 31 is (L-2W) It is formed.

  In forming the enclosure 2, the pair of first fitting plate members 20 are arranged to face each other, and the pair of second fitting plate members 30 and 30 are disposed between the first fitting plate members 20 and 20. Are disposed opposite to each other and in a direction perpendicular to the first fitting plate-like members 20. Each convex part 34 of each second fitting plate member 30 is inserted into each notch 23 of each first fitting plate member 20, and each first fitting plate member 20 is inserted into each notch 33 of each second fitting plate member 30. The pair of first fitting plate members 20 and the pair of second fitting plate members 30 are combined by inserting the respective convex portions 24 of each other, and the combination is referred to as an enclosure 2.

  Here, the tip of each convex portion 24 of the first fitting plate member 20 fitted into each recess 34 of the second fitting plate member 30 by the above-mentioned dimension setting is the main surface of the outer side of the second fitting plate member 30 The tips of the convex portions 34 of the second fitting plate member 30 which are flush with the recess 31 of the first fitting plate member 20 are flush with the surface 31 of the first fitting plate member 20 and face Become one. Therefore, the front, rear, left, and right outer end faces of the enclosure 2 are all flat vertical surfaces without unevenness, and are horizontal surfaces having a side length L and a vertical side length T. Furthermore, when T = L is set, it becomes a square surface whose length of one side is L. That is, it becomes a surface of the same shape as the main surface 11 of the basic plate-like member 10 used as the bottom plate 4 or the top plate 5.

  FIG. 11 is a view showing a rigid plate, wherein (a) is a view of the main surface as viewed from a direction perpendicular to the main surface, and (b) is a view along the main surface of the side It is the figure which looked at, FIG. 12 is a figure which shows the angle member for connection of a rigid board, Comprising: (a) is a front view, (b) is a side view, (c) is a top view.

  In addition to FIGS. 1 to 6, with reference to FIGS. 11 and 12, the bulletproof structure 1 shown comprises three rigid plates 6, each immediately after the target 9, as described above. Provided along the front end side of the enclosure 2 in the bulletproof embankment, the right end side of the enclosure 2 in the left bulletproof embankment of the target 9, the left end side of the enclosure 2 in the right bulletproof embankment of the target 9 These enclosures 2 are fastened with fasteners such as screws via the bolt holes 6a.

  Each rigid plate 6 is in the form of a thin plate, and has a square face facing the side of the enclosure 2. While it is desirable that the dimensions of this square surface cover almost the entire side surface of the enclosure 2, the three rigid plates 6 are arranged in the shape of the letter "U" in the space enclosed by the above three enclosures 2. Since it is necessary, in consideration of the thickness of the rigid plate 6 itself, the side length in the horizontal direction is L1 slightly smaller than the horizontal length L of each side of the enclosure 2 and the side length in the vertical direction is It is assumed that T1 is slightly smaller than the height T of two. If the side surface of the enclosure 2 is a square (ie, L = T), it is preferable that the side is a square whose length is L1.

  The rigid plate 6 disposed along the right end face of the left enclosure 2 of the target 9 and the rigid plate 6 disposed along the left end face of the right enclosure 2 of the target 9 It is disposed in a direction perpendicular to the rigid plate 6 disposed along the rear end face of the.

  Therefore, the front end of the rigid plate 6 on the left side of the target 9 and the left end of the rigid plate 6 just in front of the target 9 are connected via the angle member 7 made of steel or the like. The front end and the right end of the rigid plate 6 just in front of the target 9 are connected via another angle member 7. As a result, the three rigid plates 6 are connected in the shape of “コ”, the gap between the adjacent rigid plates 6 is filled with the angle member 7, and the bullet can reach the target lower device 9a through the gap. The rigidity of these rigid plates 6 is increased as well.

  A plate material bent in an L shape in plan view is used as the angle member 7. That is, the angle plate material has the plate-like portion 7a and the plate-like portion 7b which are disposed in directions perpendicular to each other. Both plate-like parts 7a and 7b are arranged to extend in the vertical direction. The plate-like member 7b is provided with a bolt hole 7c. Among them, the plate-like portion 7a is in contact with the rigid plate 6 installed along the left or right side of the bulletproof enclosure 2 of the target 9, and the plate-like portion 7b is along the bulletproof enclosure 2 immediately after the target 9. It abuts on the provided rigid plate 6 and is fastened to each rigid plate 6 with a fastener such as a bolt 8 or the like.

  Referring to the drawing, the plate-like members 10, 20 and 30 formed by molding an elastic material such as rubber as described above are members which can be easily cut with a tool such as a cutter. Therefore, when the installation site of the bulletproof levee 1 is a slope, as shown in the drawing, the lower part of the plate-like members 20 and 30 combined as the enclosure 2 is cut off with a cutter etc. according to the slope. Then, the enclosure 2 in the thus cut and processed state is installed on the slope.

  This makes it possible to ensure that all the main surfaces 21 and 31 of the four plate-like members 20 and 30 of the enclosure 2 are vertically oriented, that is, the enclosure 2 in the bulletproof levee constituting the bulletproof levee 1 The enclosure 2 may be maintained at a stable posture required, and there may be a gap between the enclosure 2 and another enclosure 2 or the enclosure 2 may collapse due to the instability of the posture. There is no stable bulletproof structure 1 can be constructed.

  Here, it is difficult to completely match the shape of the lower end of the enclosure 2 after excision to the shape of the ground surface, and it is also conceivable that a part floating from the ground surface may occur. In this regard, the basic plate member 10 is used as the bottom plate 4 and is abutted on the lower end of the enclosure 2 which has been cut, for example, without a gap, with no gap, and is fixed to the enclosure 2. Leakage of the bullet capture material 3 from the space S can be prevented.

  Here, since the basic plate-like member 10 used as the bottom plate 4 is a flexible member made of an elastic material, the bottom plate 4 is bent so as to fit the unevenness even if the lower end surface of the enclosure 2 after the cutting process is somewhat uneven. Can be made to abut without gaps. Further, in some cases, it may be considered to cut the basic plate member 10 as the bottom plate 4 on site so as to conform to the shape of the lower end of the enclosure 2.

It has an outer main surface 51b to be the other of the left end face and the right end face. Of the vertical end faces of the front ends of the main surfaces 51a and 51b and the vertical end surfaces of the rear end, a protrusion 53 projecting in the direction along the main surfaces 51a and 51b is vertically extended on one end surface 52 In the other end face 54, a groove 55 extending vertically is opened.

  The two second fitting plate members 50, 50 are disposed in a state in which they are mutually reversed. That is, the protrusions 53 of the left and right second fitting plate members 50 face the inner main surface 41 a of each first fitting plate member 40, and the grooves 55 of the other left and right second fitting plate members 50 face. . The protrusions 53 of one second fitting plate member 50 are fitted in the grooves 45 of the first fitting plate members 40, and the protrusions 43 of the first fitting plate members 40 are made of the other second fitting plate members 50. By fitting into the groove 55, the outer main surface 51b of each second fitting plate member 50, the end face 42 of the first fitting plate member 40 on one side thereof and the first fitting plate member on the other side thereof 40 and the end face 44 are flush with each other.

  Thus, a bottom plate (not shown) similar to the bottom plate 4 is attached to the bottom end of the enclosure 2X configured by combining the four plate members 40 and 50 so as to cover the bottom end opening and surrounded by the enclosure 2X.
