2. Description of the Related Art Recently, construction materials for civil engineering structures tend to be used in constructing civil engineering structures such as revetments and retaining walls. As one of the construction materials for civil engineering construction, a long wall panel is formed by using a plurality of independent wall materials and connecting lines to enhance stacking workability, and the wall panel is rearward from the back surface of the wall panel. In some cases, a plurality of extending portions are provided, and each of the extending portions is provided with a resistance increasing portion that increases movement resistance. For example, JP-A-200
1-146726 includes a wall material portion, an extension portion that extends rearward from the wall material portion with the same length as the vertical width of the wall material portion, and a flange-shaped resistance force increase provided in the extension portion. A plurality of civil engineering blocks that are integrally formed with concrete parts are prepared, and the plurality of civil engineering blocks are connected by connecting lines to form a long wall panel with the wall material of each civil engineering block. It is shown. In this thing, since the long wall panel is composed of the wall material parts of the plurality of civil engineering blocks, the number of stacking works can be reduced compared to the case where the civil engineering blocks are individually stacked, and, It is also possible to bend the connecting line between the civil engineering blocks to bend the wall panel.

[0003]

However, each of the civil engineering blocks in the construction material for civil engineering structures described above is not only a wall material portion but also an extension portion extending rearward and a resistance force increasing portion provided in the extension portion. The part of is also composed of a concrete block in order to secure weight stability, movement resistance and the like, and each civil engineering block itself is a heavy object. For this reason, when it is decided to connect a plurality of civil engineering blocks to form a wall panel, if it is used, the number of stacking constructions can be reduced,
The stacking work itself becomes large-scale, and further, fine adjustment at the time of stacking cannot be easily performed.

The present invention has been made in consideration of the above circumstances, and the first technical problem is not only that the number of times of stacking for constructing a civil engineering structure can be reduced but also that a series of stacking can be performed. It is to provide a construction material for a civil engineering structure that can facilitate work. The 2nd technical subject is providing the manufacturing method of the construction material for civil engineering structures which manufactures the construction material for civil engineering structures mentioned above. A third technical problem is to provide a civil engineering structure using the construction material for civil engineering structure described above.

[0005]

In order to achieve the first technical object, the present invention (the invention of claim 1) comprises:
A long wall panel is formed by using a plurality of independent wall members and connecting lines, and the wall panel is provided with a plurality of extension portions extending rearward from the back surface of the wall panel, and each extension portion In the construction material for civil engineering construction, each of which is provided with a resistance increasing portion that increases movement resistance, each of the extending portions is a wire.

The adjustment can be easily performed. Moreover, when the connecting wire is bent between the wall members, since the extension portions are wires that are considerably narrower than the vertical width of the wall panel, it is possible to easily avoid the extension portions from interfering with each other. As a result, the wall panel can be bent at a right angle as well as being simply curved, and the curvature of the wall panel can be considerably increased. Therefore, the degree of freedom in determining the curvature of the wall panel can be increased.

According to the fifth aspect of the present invention, a part of the plurality of wall materials is provided with a back wall of the wall panel, which has substantially the same length as the vertical width of the wall panel. Since the pillars are integrally provided, even if the wall panels are panel-shaped, the retaining pillars are used to stack the wall panels in a plurality of steps without filling the backfill material (standing up). ), It is possible to speed up the work and improve the workability as compared with the case where the backfill material is filled every time the wall panels are stacked.

According to the invention described in claim 6, since the through hole for passing the connecting wire is formed in the up-down direction in the stay column portion, if the construction material for civil engineering construction is piled up, it penetrates. The holes are connected, and by passing the connecting wire through the through holes, the integration of the building materials for civil engineering structures can be enhanced, and the civil engineering structures can be further strengthened.

According to the invention described in claim 7, the connecting line penetrates the plurality of wall members in the arrangement direction of the plurality of wall members, and the connecting line is bent by a load of a predetermined value or more. Since it is set as described above, the connection strength between the wall surface materials can be secured, while the wall surface panel can be surely bent or curved.

According to the invention described in claim 8, since the stopper panel is provided on the wire as the resistance increasing portion, the movement resistance can be properly secured by the stopper panel, while the stopper panel is light. Therefore, it is possible to further reduce the weight of the construction material for civil engineering structure.

A connecting wire is embedded so as to straddle each of the wall materials inside, and then a mounting hole is formed in the uncured state of each of the wall materials. Then, after hardening of each of the wall materials, an anchor is provided in the mounting hole. Since one end of the wall is attached, it is possible to form wall panels by connecting the wall materials with connecting wires. When forming mounting holes for the wall panels (wall materials), use the uncured state of concrete. Therefore, the anchor can be easily attached to the wall panel by using the attachment hole. Therefore, the construction material for civil engineering structures according to claim 1 can be easily manufactured.

According to the invention described in claim 10, as a construction material for civil engineering construction, a long wall panel in which a plurality of independent wall materials are connected via connecting lines, and from the back surface side of the wall panel A plurality of wire rods extending rearward and a plurality of resistance force increasing portions provided on the wire rods are prepared,

Corresponding to 0, the positioning protrusion 11 is formed to be fittable.

In the present embodiment, the anchor 5 is connected to each of the pseudo stone blocks 6 by its one end (the left end in FIG. 1), as shown in FIGS. 1, 3 and 4. . This anchor 5 has a pseudo stone block 6
In order to prevent the movement (sliding) during use (when piled up) with the backfill material (body material: embedding material for burying the anchor 5, for example, earth and sand, split stone, crushed stone, etc.) 12 (extended portion, wire), curled portion 13 as a curved portion
A (resistance force increasing portion), a stopper panel 14 (resistance force increasing portion) and the like are provided.

The shaft portion 12 and the curl portion 13 are integrally formed of a straight material. In consideration of strength, workability, etc., the linear material is preferably an iron wire, a reinforcing bar, a pipe, etc.
In this embodiment, an iron wire having a wire diameter of about 6 mm (containing about 10% of aluminum) is used. It is preferable to form a plating layer and a resin coating layer on the outer periphery of this straight material for the purpose of preventing rust. The shaft-shaped portion 7 extends straight, and the total length L5 thereof is about 0.5 to 1.5 m, preferably about 0.5 m to 0.8 m.
A male screw 32 is formed on the outer periphery of one end of the shaft-like portion 12, and the male screw 32 is screwed to the insert nut 31 in the pseudo stone block 6 via a resin cylinder 30.

As shown in FIGS. 1 and 3, the curl portion 13 is formed by curling the other end portion (the left end portion in FIG. 1) of the shaft-shaped portion 13 into a curl shape. In the curl portion 13,
A circular hole having an inner diameter of about 30 mm is formed, and after the hole is formed, the other end portion (curved end portion) of the anchor 5 is
It is supposed to be wound around the shaft-shaped portion 12 as a winding portion.

As shown in FIGS. 1 and 3, the stopper panel 14 is movably held by the shaft-shaped portion 12 with its plate surface oriented in the extending direction of the shaft-shaped portion 12. The stopper panel 14 is made of resin, for example, ABS resin, and is a square synthetic resin plate having a side of about 150 mm and a thickness of about 6 mm, and an insertion hole (not shown) is formed in the center thereof. ing. The shaft-shaped portion 12 is inserted through the insertion hole of the stopper panel 14, and the stopper panel 14 can move the shaft-shaped portion 12 while the curl portion 13 restricts the movement.

In order to construct the retaining wall 1 using the construction material 2 for civil engineering construction (per unit section (one lateral length of construction material 2 for civil engineering construction)), construction for civil engineering construction The materials 2 are sequentially stacked in a stepwise manner from the basic concrete 3. In this case, the pair of retaining columns 9 of the construction material 2 for civil engineering structures, which are vertically related, are arranged so as to overlap each other, and the lower stage thereof. The positioning projections 11 of the construction material 2 for civil engineering structures on the side contact the wall surface panel 4 of the construction material 2 for civil engineering structures on the upper side to perform longitudinal positioning. Of course, the positioning groove 10 and the positioning projection 11 of each construction material 2 for civil engineering construction are provided as shown in FIG. 6, and the positioning projection 11 of the construction material 2 for civil engineering construction on the lower side is the construction material for civil engineering construction on the upper side. The positioning may be performed by fitting into the second positioning groove 10. On the other hand, as the building materials 2 for civil engineering structures are piled up, the anchors 5 extend substantially horizontally rearward from the wall panel 4 in the building materials 2 for civil engineering structures. It is buried by 15. The filling of the backfill material 15 is performed every time the construction material 2 for civil engineering construction is stacked, and in the present embodiment, plants are placed between the steps of the construction material 2 for civil engineering construction (wall surface panel 4) that are vertically arranged. In order to make it grow, each of the construction materials 2 for civil engineering structures has a wall panel 4 to a retaining column 9
The vegetation earth and sand 16 are filled up to the area up to, and the regeneration crusher (C
₄₀ to ₀ ), crushed stones, crushed stones, etc. 17 are filled, and their engagement with the stopper panel 14 ensures a large forward movement resistance. In FIG. 1, reference numeral 18 is a top concrete, and reference numeral 19 is a suction preventing sheet.

Therefore, if such a construction material 21 for civil engineering construction is used for stacking, each construction material 2 for civil engineering construction is
It is possible to exert a large movement resistance based on the engagement between the stopper panel 14 and the back-filling material 15 in the above-described manner with respect to all the pseudo stone blocks 6 (wall surface panels 4) via the reinforcing bars 8, thus constructing a strong retaining wall 1. You will be able to do it.

In this case, since the wall surface panel 4 in which a plurality of pseudo stone blocks 6 are connected is used, the number of stacking operations can be reduced as compared with the case where the pseudo stone blocks 6 constituting the wall surface panel 4 are individually stacked. On the other hand, the construction material 2 for civil engineering construction uses a concrete block only for the pseudo stone block 6 and uses lightweight elements 12 and 14 of the anchor 5, thereby reducing the weight of the construction material 2 for civil engineering construction. This makes it possible (in the present embodiment, a weight of about 130 kg) to not only reduce the work load of stacking the construction material 2 for civil engineering structures, but also to easily and finely adjust the position at that time manually. You will be able to

In the construction material 2 for civil engineering construction, the concrete block is used only for the pseudo stone block 6, and the anchor 5 is used.
Since only the thin shaft-shaped portion 12 and the stopper panel 14 are provided, when the wall surface panel 4 is bent, even if the shaft-shaped portion 12 of each construction material 2 for civil engineering structures intersects, There is no interference, and even if there is a risk of interference, the anchor 5 can be bent to easily avoid interference. Therefore, as shown in FIG. 7, not only can the wall panel 4 be curved, but the wall panel 4 can also be bent at a right angle, which makes it possible to appropriately cope with the construction of various civil engineering structures.

Next, a method for manufacturing the construction material 2 for civil engineering structure will be described. First, as shown in FIG. 8, a wall panel molding die 22 having a plurality of pseudo stone block equivalent spaces 21 in series is prepared, and two pseudo stone block equivalent spaces 21 in the wall panel molding die 22 are provided. Reinforcing bar 8
Are stored while crossing all the spaces 21 corresponding to the pseudo stone blocks. In this case, the two reinforcing bars 8 are held by the wall panel molding die 22 with a removable pressing plate 23.

Next, as shown in FIG. 8, concrete is poured into the wall panel molding die 22. This is because a plurality of independent pseudo stone blocks 6 are formed and embedded in the plurality of pseudo stone blocks 6 so as to cross the two reinforcing bars 8.

Next, as shown in FIG. 9, while each pseudo-stone block 6 in the wall panel molding die 22 is in an uncured state, the column columns are set at two predetermined positions on the wall panel molding die 22 (flange). While fixing the molding die 24 (the fixture is not shown), the belt-shaped support member 25 having a plurality of bolts 26 for holding the insert nut 31 (fitting state) via the resin cylinder 30 is placed in a substantially horizontal state. Wall panel mold 22
Then, the insert nut 31 and the resin cylinder 30 held by the bolts 26 are inserted into the quasi-stone blocks 6 in the uncured state after being fixed to the buttress column molding die 24. The insert nut 31 is prepared by making preparations for forming the retaining column 9 and utilizing the fact that it is in an uncured state in the back surface side of each pseudo stone block 6.
This is for embedding the resin cylinder 30. In this case, in the present embodiment, the stay column part forming die 24 is arranged so as to face the second pseudo stone block 6 from both sides in the lateral direction toward the inner side.

Next, as shown in FIG. 9, while the pseudo stone blocks 6 in the wall panel molding die 22 are in an uncured state, the retaining pillar portion molding die 24 is filled with concrete. This is because the pair of retaining columns 9 are integrally provided on the back surface of the wall panel 4.

Next, the concrete in the wall panel molding die 22 and the retaining column molding die 24 is hardened and then removed. In this case, the support member 25 is removed from the wall surface panel molding die 22 and the retaining column portion molding die 24 and lifted up to remove each bolt from each resin cylinder 30. At this time, since the insert nut 31 is provided with the flange portion 31a and the outer diameter of the resin cylinder 30 is expanded toward the inner side of the pseudo stone block 6, the insert nut 31 and the like do not come off at the same time. After that, the wall panel 4 is taken out from the wall panel mold 22. When taking out the wall surface panel 4 from the wall surface panel forming die 22, it is preferable to attach a hook metal fitting to the pseudo stone block 6 and apply a take-out force to it.

Next, as shown in FIG. 10, the wall surface panel 4
The male screw 32 at one end of the anchor 5 is screwed into the insert nut 31 of each pseudo stone block 6 in FIG. As a result, one end of the anchor 5 is integrated with each pseudo stone block 6, and the construction material 2 for civil engineering construction is obtained.

FIG. 11 shows the second embodiment, FIG. 12 shows the third embodiment, and FIGS. 13 and 14 show the fourth embodiment. In each of the embodiments, the same components as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

The second embodiment shown in FIG. 11 shows a modification of the construction material for civil engineering structures according to the first embodiment. In the construction material 2 for civil engineering structures according to this embodiment, the anchors 5 are not provided on all the pseudo stone blocks 6 in the wall panel 4, and the anchors 5 are provided only on a part of the pseudo stone blocks 6. However, even with such a configuration, it is used that all the pseudo stone blocks 6 are connected by the reinforcing bars 8 and that the resistance by the stopper panel 14 provided in a part of the pseudo stone blocks 6 is sufficient. Then, the movement resistance of the entire wall surface panel 4 can be secured by the resistance force of a part of the pseudo stone block 6. On the other hand, by reducing the number of anchors 5, it is possible to further reduce the weight of the construction material 2 for civil engineering construction and to further facilitate the construction at the time of stacking.

In the third embodiment shown in FIG. 12, the wall panel 4 is stacked so as to form an inclined surface.
In this case, in the case where each wall panel 4 forms an inclined surface, one end of the anchor 5 is bent in consideration of the fact that the anchor 5 extends downward and the resistance is reduced as it is. Even if 4 forms an inclined surface, each anchor 5 is supposed to be extended substantially horizontally. Further, in this case, even if the wall panel 4 has a panel shape, the wall panel 4 is stacked (raised) in a plurality of steps (for example, two steps) without using the back column material 9 to fill the backfill material 15. ) It will also be possible to use the wall panel 4
As compared with the case where the backfilling material 15 is filled every time the sheets are stacked, the work can be speeded up (a part of the step of filling the backfilling material 15 is omitted), and the workability can be improved.

In particular, in the present embodiment, when the construction material 2 for civil engineering construction is stacked, the positioning projections 11 of the construction material 2 for civil engineering construction in the lower stage are fitted into the positioning grooves 10 of the construction material 2 for civil engineering construction in the upper stage. Since it is configured, if at least the lowest construction material 2 for civil engineering construction is made immovable based on the movement resistance force of the anchor 5 and the backfill material 15, the backfill material 15 will be described below.
Constructing materials for multiple civil engineering structures 2 without filling
Could be stacked, or even more civil construction material 2 could be stacked without backfilling material 15 filling.

The fourth embodiment shown in FIGS. 13 and 14 shows a modification of the third embodiment. In this 4th Embodiment, as shown in FIG. 14, the vertical hole 35 as a through-hole is each formed in the retaining column part 9 of each construction material 2 for civil engineering structures, and each construction material 2 for civil engineering structures is formed. When piled up, the vertical holes 35 of the retaining column portion 9 in each construction material 2 for civil engineering structures are to be continuously connected. On the other hand, a reinforcing bar 36 as a connecting wire is held in the concrete foundation 3 with its lower end portion.
6 is to be launched upward from the foundation concrete 3. Then, in the reinforcing bar 36, the vertical hole 35 of the retaining column portion 9 in each of the construction materials 2 for civil engineering structures described above.
And the vertical holes 35 are to be filled with mortar, and the integrity of the construction material 2 for civil engineering construction is further enhanced. For this reason,
In the fourth embodiment, a stronger retaining wall 1 can be obtained.

It should be noted that the object of the present invention is not limited to what is specified, but also implicitly includes providing what is substantially preferred or described as an advantage.
