  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment described below is merely an example, and there is no intention to exclude various modifications and technical applications that are not explicitly described below. The present invention can be implemented with various modifications (for example, by combining the embodiments) without departing from the spirit of the present invention. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. The drawings are schematic and do not necessarily match actual dimensions and ratios. In some cases, the dimensional relationships and ratios may be different between the drawings.

  FIG. 1 is a schematic side view showing an example of a civil engineering structure according to an embodiment of the present invention. As shown in the figure, the civil engineering structure 1 configured as a retaining wall is a structure that forms a retaining wall, a seawall, etc., and a plurality of civil engineering construction blocks 20 are stacked on the foundation 10. Built. In the civil engineering structure 1 of this example, trunk concrete or back concrete 40 is placed on the back of the civil construction block 20 installed along the backfilling material 30 having a predetermined legal gradient, and the uppermost part thereof. The top end concrete 50 is casted in. The civil engineering building block 20 is connected to the column reinforcement 70 arranged on the front surface of the backfilling material 30 through the fixing member 60 of the civil engineering building block 20 at the time of construction. Is possible. In addition, although strictly concrete and backfill concrete are different, in this specification, these are simply referred to as backfill concrete 40 unless there is a particular significance for distinguishing between them.

  The foundation 10 is configured, for example, by laying a foundation crushed stone 11 on a ground 80 ground and placing a foundation concrete 12 thereon. The upper end portion of the foundation concrete 12 has, for example, an inclined surface 12a that is inclined toward the slope 82, so that the civil engineering building block 20 can be stacked to form a predetermined wall surface gradient. .

The civil engineering building block 20 is a building material including a concrete block main body having a thickness that can sufficiently withstand, for example, a revetment. The shape and size of the civil engineering building block 20 can be selected as appropriate. For example, the surface of the civil engineering building block 20 (that is, the surface constituting the wall surface) may be formed as if a plurality of pseudo stone blocks are provided, or a geometric texture may be formed. good. Alternatively, for example, natural stones may be embedded in the surface so as to harmonize with the natural environment. The civil engineering building block 20 of this example is configured by integrally connecting a plurality of concrete blocks. In addition, the civil engineering building block 20 of this example includes a fixing member 60 for connecting to the column reinforcement 70. Details of the civil engineering building block 20 will be described later.

  The column reinforcement 70 is, for example, an iron reinforcement for reinforcing the backfilled concrete 40 to be placed. In this example, the civil engineering building block 20 is attached to the column reinforcement 70 via the fixing member 60. For example, one end of the column 70 is fixed in the foundation concrete 12. At this time, the column reinforcement 70 may be fixed by drilling and driving one end to which an anchor (not shown) is attached into the foundation concrete 12 that has been placed. Alternatively, the column reinforcement 70 may be fixed by inserting one end thereof into a mounting hole formed by embedding an insert nut in the foundation concrete 12, or the concrete constituting the foundation concrete 12 is uncured. In step, it may be fixed by embedding one end thereof. Further, the column bars 70 are connected to each other through, for example, a high nut or a connection nut, and can be raised to a predetermined height along the normal gradient of the backfill material 30. Furthermore, a spacer 72 can be attached to the column reinforcement 70 in order to ensure the cover thickness of the backfill concrete 40. The cross-sectional shape of the column 70 can be selected arbitrarily, and the surface may have an uneven shape in order to increase the concrete adhesion rate.

  The fixing member 60 is a member that connects the civil engineering building block 20 and the column reinforcement 70. The fixing member 60 is made of, for example, a metal such as iron or a stainless alloy, but is not limited thereto, and may be made of, for example, a fiber reinforced resin. The fixing member 60 is attached in advance to the back surface of the civil engineering building block 20, for example. At the time of construction, the civil engineering building block 20 is temporarily fixed to the column bar 70 by the fixing member 60, thereby improving the self-supporting stability of the civil engineering building block 20 and ensuring the integrity with the filled backfill concrete 40. can do. Details of the fixing member 60 will be described later.

  The backfill concrete 40 is concrete that is placed in the back space of the installed civil engineering building block 20, that is, in the space formed between the back surface of the civil engineering building block 20 and the front surface of the backfilling material 30. When placing the backfilling concrete 40, for example, a punching mold frame 90 as shown in FIG.

  FIG. 2 is a diagram showing an example of a civil engineering building block according to an embodiment of the present invention. Specifically, FIG. 2A is a front view of the civil engineering building block, and FIG. 2B is a plan view thereof. Fig. C is a side view thereof, and Fig. D is a rear view thereof. As shown in these drawings, the civil engineering building block 20 includes, for example, a panel coupling body 21, a retaining pillar 22, and a fixing member 60. 2D shows a state where the fixing member 60 is removed.

  The panel coupling body 21 includes a wall surface panel 23, a coupling member 24, and a fixing anchor 25. The panel coupling body 21 is formed, for example, by connecting five wall surface panels 23 via a coupling member 24 in the transverse direction.

  The wall surface panel 23 may have, for example, an uneven texture that harmonizes with the natural environment on its surface. For example, the wall surface panel 23 may be a concrete block formed in a pseudo stone shape. Alternatively, the wall panel 23 may be formed with a geometric texture. The size of the wall surface panel 23 is, for example, about 250 mm in length, about 400 mm in width, and about 100 mm in thickness.

  As shown in FIG. 2A, the connecting member 24 is, for example, an iron reinforcing material that communicates through the inside of the wall surface panels 23 arranged in a row and connects the wall surface panels 23 to each other. In this example, the five wall panels 23 are integrally connected by two parallel connecting members 24. With such a configuration, the series of wall surface panels 23 can be bent freely at the connection portion thereof, and the panel connection body 21 having a curved portion can be obtained. When such a panel coupling body 21 is configured, for example, a joint material is injected into the coupling portion.

  The fixing anchor 25 is, for example, an iron bar extending backward from the back surface of the panel connector 21. In this example, the fixing anchor 25 is formed in an L shape in a side view as a whole by bending the far end portion downward. The fixing anchor 25 can be attached to the wall panel 23 by any method. For example, the anchor 25 for fixing may be attached by embedding one end portion of the rear surface of the wall surface panel 23 in a stage where the concrete constituting the wall panel 23 is uncured. Alternatively, the fixing anchor 25 may be attached by screwing one end thereof into an attachment hole formed by embedding an insert nut in the back surface of the wall surface panel 23. For example, the fixing anchor 25 is provided on the wall surface panel 23 other than the wall surface panel 23 provided with the post 22 described later.

  As shown in FIGS. 2B and 2D, the conservative pillar 22 is a block body provided in a part of the wall surface panel 23 that constitutes the panel coupling body 21. In this example, it is provided in the back surface of the wall surface panel 23 located in the 2nd from the left-right end among the five wall surface panels 23, respectively. When the wall surface panel 23 is formed, the conservative column 22 is formed integrally with the wall surface panel 23 using concrete. The reserved column 22 has a height substantially the same as the height of the wall surface panel 23, and is recognized as a substantially prismatic portion as a whole that protrudes rearward from the back surface of the wall surface panel 23 by a predetermined length. The rear protrusion length (that is, the depth length) of the storage pillar 22 is, for example, about 250 mm, and is set to be longer than the extension length of the fixing anchor 25.

  Further, as shown in FIG. 2D, an attachment hole 26 for attaching the fixing member 60 is formed on the back surface of the retaining pillar 22. In the attachment hole 26, for example, an insert nut (not shown) in which a resin cylinder (not shown) (for example, made of ABS resin) is fitted is embedded. In order to arrange the resin cylinder and the insert nut with high positional accuracy, the resin pillar 22 and the wall surface panel 23 may be embedded in the pillar 22 when integrally formed with the pillar 22 and the wall surface panel 23 with concrete.

  Moreover, you may provide the hole for fixing pins which is not shown in figure on the upper surface and bottom face of the pillar 22. The holes of the fixing pins are used for stacking the civil engineering building blocks 20 so as to form a predetermined wall slope. Specifically, one end of a fixing pin (not shown) is inserted into a hole for a fixing pin provided on the upper surface of the stay pillar 22 of the civil engineering building block 20. When another civil engineering building block 20 is stacked on the civil engineering building block 20, the other end of the fixing pin is inserted into the fixing pin hole provided on the bottom surface of the retaining column 22. To do. By doing in this way, the civil engineering construction block 20 can be piled up so that it may become a desired wall surface gradient. Note that a plurality of fixing pin holes may be provided corresponding to the wall surface gradient of the civil engineering building block 20 and used depending on the desired wall gradient of the civil engineering building block 20.

  As shown in FIGS. 2B and 2C, the fixing member 60 is attached to the back surface of the retaining column 22. Details of the fixing member 60 will be described later.

  FIG. 3 is a diagram illustrating an example of a fixing member according to an embodiment of the present invention. Specifically, FIG. A is a front view of the fixing member, and FIG. B is a plan view thereof. As shown in these drawings, the fixing member 60 includes, for example, a joining portion 61 and an engaging portion 62, and is formed symmetrically with respect to a virtual axis a corresponding to the long axis direction of the columnar bars 70. Is done. The fixing member 60 is typically a metal member such as iron or stainless alloy, but is not limited thereto, and may be a fiber reinforced resin member. For example, if the fixing member 60 is made of iron, the fixing member 60 is formed by punching a steel plate having a predetermined thickness into a plate material having a predetermined shape by punching, and forming the engaging portion 62 by bending. Produced.

  The joining part 61 has a joining surface 61a and is, for example, a part formed in a plate shape symmetrically with respect to the virtual axis a and joined to the back surface of the civil engineering building block 20. In the joint portion 61, for example, an opening portion 63 into which a fastener 27 such as a bolt (see FIG. 4) is inserted on the left and right sides around the virtual axis a is formed. When the fixing member 60 is attached to the back surface of the civil engineering building block 20, the opening 63 is positioned in the attachment hole 26 on the back surface of the civil engineering building block 20. In this example, the opening 63 is formed in a slit shape so that it can be fitted to the mounting holes 26 at various intervals.

  The engaging portion 62 is a portion that engages with the column reinforcement 70 and thereby couples the fixing member 60 and the column reinforcement 70, and includes, for example, a base portion 64, a wall portion 65, and a claw portion 66. Composed. For example, the base 64 is a portion extending in the vertical direction from the joint 61 along the virtual axis a. Both side edges of the base portion 64 rise by a predetermined height to form a wall portion 65, and the tip of the wall portion 65 is bent in the direction toward the virtual axis a (that is, inward), thereby Form. The engaging portion 62 allows the columnar muscle 70 to be received in the space formed as described above, and prevents the received columnar rod 70 from being detached by the claw portion 66. In addition, in this example, although the wall part 65 thru | or nail | claw part 66 are formed in linear form (refer FIG. 3B), it is not restricted to this. For example, as shown in FIG. 3C, the wall portion 65 may be formed so that the space for receiving the column reinforcement 70 is curved. Alternatively, as shown in FIG. 3D, the wall portion 65 may be formed in a curved shape, and the tip of the claw portion 66 may be folded back and spread outward.

  FIG. 4 is a view for explaining an attachment state of the fixing member according to the embodiment of the present invention. As shown in the figure, the fixing member 60 is joined via a fastener 27 by joining a joining surface 61 a to the back surface of the retaining column 22 of the civil engineering building block 20. Thereby, the fixing member 60 is integrated with the civil engineering building block 20 and constitutes a part of the civil engineering building block 20. In this case, the engaging portion 62 is positioned so as to face the rear side of the column 22. In this state, when the engaging portion 62 is pressed against the column reinforcement 70, the wall portion 65 bends outward to receive and hold the column reinforcement 70, whereby the fixing member 60 is connected to the civil engineering building block 20. The column bar 70 is connected.

  In the above example, one fixing member 60 is attached to one constraining column 22 and is connected to the column bar 70. However, the present invention is not limited to this. A plurality of fixing members 60 may be attached to 22 and connected to the column reinforcement 70.

  Next, the construction method of the civil engineering structure using the civil engineering building block of this embodiment is demonstrated. FIG. 5 is a flowchart for explaining a construction method for a civil engineering structure according to an embodiment of the present invention. In this example, it is assumed that the civil engineering building blocks 20 are stacked in a plurality of stages.

  First, a foundation work for forming the foundation 10 is performed (S501). In this step, the foundation crushed stone 11 is laid on the ground 80, and the foundation concrete 12 is placed thereon. At this time, for example, one end of the column reinforcement 70 is embedded in the foundation concrete 12 and fixed.

  Subsequently, the column reinforcement 70 is raised to a required height (S502). FIG. 6 is a diagram illustrating this process. The column reinforcement 70 is raised to a required height by connecting the reinforcement using a high nut (not shown) at the end opposite to the end embedded in the foundation concrete 12. The rising height of the column 70 may be a height corresponding to the number of stages of the civil engineering building block 20 to be stacked in S503 described later, and does not need to be raised to a finally required height as the civil engineering structure 1.

  Returning to FIG. 5, next, the civil engineering building block 20 is stacked on the foundation concrete 12, the installation position is adjusted, and the fixing member 60 is pressed against and fitted into the column reinforcement 70, whereby the civil engineering building block 20 is inserted into the column reinforcement. 70 is connected (S503). FIG. 7 is a diagram illustrating this process. Here, the civil engineering building blocks 20 are stacked in two stages on the inclined surface 12a of the foundation concrete 12. However, the civil engineering building blocks 20 may be stacked one by one or in multiple stages. In addition, when the civil engineering building block 20 is stacked, after one end of the fixing pin is inserted into the fixing pin hole provided on the upper surface of the retaining column 22 of the lower civil engineering building block 20, the civil engineering building block on the upper stage side is inserted. The other end of the fixing pin may be inserted into the 20 fixing pin hole. By doing in this way, the civil engineering construction block 20 can be piled up so that it may become a desired wall surface gradient.

  Returning to FIG. 5, next, the punching mold 90 is installed (S504). FIG. 8 is a diagram illustrating this process. The punching mold frame 90 is installed at a predetermined position between the column bar 70 and the slope 82. In addition, a spacer 72 is disposed between the column reinforcement 70 and the punching mold frame 90 in order to ensure the cover thickness of the backfill concrete 40. Prior to this step, a drain pipe (not shown) may be installed.

  Returning to FIG. 5, next, the backfill material 30 is laid between the slope 82 and the punching mold frame 90, and is compacted (S505). FIG. 9 is a diagram for explaining this process, and the backfill material 30 is filled between the slope 82 and the punching mold frame 90.

  Returning to FIG. 5, next, after filling the space between the civil engineering building block 20 and the punching mold 90 and placing the backfill concrete 40, the punching mold 90 is removed (S506). FIG. 10 is a diagram for explaining this process, in which backfill concrete 40 is placed. As shown in the figure, typically, the backfill concrete 40 is up to the extent that the anchoring anchor 25 of the upper civil engineering building block 20 is hidden (for example, about 2/3 of the height of the civil engineering building block 20). To cast.

  Returning to FIG. 5, it is then determined whether or not the construction of the planned number of civil engineering building blocks 20 has been completed (S507). If the construction of the planned number of civil engineering building blocks 20 has not been completed (No in S507), the process returns to S502 and the construction of the civil engineering structure 1 is continued. On the other hand, when the construction of the planned number of civil engineering building blocks 20 has been completed (Yes in S507), the top concrete 50 is placed (S508), and the construction of the civil engineering structure 1 is completed.

  Each of the above embodiments is an example for explaining the present invention, and is not intended to limit the present invention only to these embodiments. The present invention can be implemented in various forms without departing from the gist thereof.
