Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIG. 3.

As shown in Figure 3 below, the reinforcement earth retaining wall according to the present invention includes a surface material structure that is installed with a predetermined spaced space in front of the rear soil (1), the surface material structure is a plurality of joint block 110 is At least one joint wall 100 constructed in a straight line along the vertical direction; Connected to the left and right sides of the joint wall 100, respectively, a plurality of surface blocks 210 are configured to include a plurality of surface walls 200 are stacked in the vertical direction.

That is, the plurality of surface walls 200 may be constructed in a stacking manner to sufficiently secure mechanical stability. In addition, since the plurality of surface walls 200 are stretched by the joint wall 100, cracks may be prevented in response to stress caused by thermal expansion and contraction after construction. Therefore, the reinforced earth retaining wall according to the present invention can obtain the effect that the mechanical stability can be increased, and the maintenance can be facilitated.

At least one of the joint block 110 and the surface block 210 is formed so that the other one can be engaged, so that the engaging block 110 and the surface block 210 of the engaging block by the engaging portion. It can further take advantage of the fact that mutual cohesion can be made stronger.

The engagement portion may be formed in various ways, and may be formed in at least one engagement groove (H) in which one of the joint block 110 and the surface block 210 is inserted and the other one may be inserted therein. . That is, as shown in the outer surface of the surface block 210, the engaging groove (H) that can be inserted into a portion of the joint block 110 may be formed, or not shown, but the joint block if necessary An engaging groove H may be formed on the outer surface of the 110 so that a part of the surface block 210 may be inserted.

As the engaging portion is formed in this way, the shape of the joint block 110 and the surface block 210 can be advantageously formed.

Here, the engaging groove (H) may be formed in the surface block 210 as shown, and may be formed in the joint block 110 as necessary, although not shown.

In addition, the engaging groove (H) may be penetrated in the vertical direction so that the surface block 210 and the joint block 110 does not interfere with each other (222) in the vertical direction, as shown, The joint block 110 may be formed to be inserted only in the left and right directions.

In addition, the joint block 110 and the surface block 210, as indicated by the 'A' in Figs. 4 and 5 are formed in a curved surface, the surface block 210 is a joint The block 110 may be rotated within a range.

That is, the retaining wall construction of the straight section by the joint block 110 and the surface block 210 as shown in Figure 3, as well as the retaining wall construction of the bending and bending section as shown in Figures 12 and 13 It can be done easily. Therefore, it is possible to further take advantage of the construction of the reinforced soil retaining wall of a variety of structures according to the terrain conditions.

In particular, the surface block 210 is formed of two types of the basic block 220 and the auxiliary block 230, and the surface wall 200 is formed of at least one agent made of a plurality of basic blocks 220 built in the left and right directions 1 block body 212; A plurality of basic blocks 220 are alternately formed between the basic block portion 214A and the basic block portion 214A and the joint block 110 that are alternately constructed with the basic block 220 of the first block body 212 along the left and right directions. It may be configured to include; at least one second block body 214 made of an auxiliary block 230 constructed in.

That is, in the second block body 214, even if the basic block portion 214A is constructed at a distance from the joint block 110 for stack construction with the first block body 212, the auxiliary block 230 is It fills between the basic block portion 214A and the joint block 110. Accordingly, the surface wall 200 may be constructed in a staggered manner for mechanical stability, and may be constructed such that there is no gap between the wall wall 100 and the joint wall 100.

The basic block 220 may not only take the shape as shown, but may also take various shapes as necessary.

The auxiliary block 230 may take any shape as long as it can firmly fill the space between the basic block portion 214A and the joint block 110 in the second block body 214.

However, the auxiliary block 230 has a shape that is the same as the shape of a portion of the basic block 220, as shown, the surface wall 200 can take a consistent structure as a whole, the nerve to fit the shape The surface wall 200 can be easily constructed without the need for writing, and the shape of the surface wall 200 may be similar to that of the basic block 220, so that it may be easily manufactured together with the basic block 220.

Furthermore, the shape of the auxiliary block 230 is a basic block 220 so that the basic block 220 of the first block body 212 and the basic block 220 of the second block body 214 can be stacked in half. It can take the shape similar to the external shape of the half membrane.

In the surface wall 200, as illustrated, the first block body 212 and the second block body 214 may be alternately constructed along the vertical direction. In addition, if necessary, at least one of the first block body 212 and the second block body 214 may be continuously constructed in two or more steps along the vertical direction.

On the other hand, the surface wall 200 is not mechanically uniformly distributed in a plurality of surface blocks 210 is stress is not evenly distributed over a plurality of surface blocks 210 and concentrated in some of the surface block 210 by mechanical Stability is not sufficiently secured. In addition, the surface wall 200 may not look good unless a plurality of surface blocks 210 are consistently constructed.

Accordingly, the plurality of surface blocks 210 are preferably constructed at precise positions with each other for structural consistency and mechanical stability of the surface wall 200.

In this case, the plurality of surface blocks 210 may be engaged with the basic block 220 or the auxiliary block 230 constructed on the upper surface of the base block 220 so as to guide the positions where the plurality of surface blocks 210 are constructed with each other. At least one key 222 may protrude.

Therefore, since the plurality of surface blocks 210 can be easily constructed at the correct position with each other without special effort, construction properties and mechanical stability can be increased, and construction can be easily and simply made. have.

The key 222 of the basic block 220 may be formed to be specifically engaged with the vegetation holes 224 and 234 of the basic block 220 or the auxiliary block 230 constructed thereon.

Of course, in the basic block 220 or the auxiliary block 230, a key engaging portion such as a groove may be additionally formed so that the key 222 of the basic block 220 may be engaged, but the present invention may separately form a key engaging portion. Since there is no need, the basic block 220 or the auxiliary block 230 may be formed in a simple structure, and may further take advantage of preventing degradation of durability and stress concentration due to the formation of the key engagement portion.

Furthermore, the key 222 of the basic block 220 is formed on the left and right sides of the vegetation holes 224 and 234 of the basic block 220, respectively, and the vegetation holes 224 and 234 of the basic block 220 constructed thereon. By being inserted in close contact with the left and right inner surface of (), in particular (see Fig. 5), it is possible to further take advantage of the fact that the basic block 220 constructed on the upper side can be firmly constrained at both the left and right at the same time.

On the other hand, the auxiliary block 230 may be formed to engage the key 222 of the basic block 220 built below the vegetation hole 234 of the auxiliary block 230 as described above, As described above, a key groove 232 may be formed on an outer surface thereof so that the key 222 of the basic block 220 constructed below may be inserted and engaged.

The key groove 232 of the auxiliary block 230 is formed on the outer surface of the auxiliary block 230 separately from the vegetation hole 234 formed in the auxiliary block 230, thereby providing a basic structure without structural interference with the auxiliary block 230. It may further take advantage that the location and shape of the key 222 of the block 220 can be easily and variously determined.

In addition, at least one of the basic block 220 and the auxiliary block 230 may be formed with at least one vegetation hole (224, 234) as described above so that the vegetation soil for vegetation is filled as described above. .

The vegetation holes 224 and 234 may be penetrated along the vertical direction as shown in FIGS. 4 to 7, but the vegetation soil is prevented from falling out due to soil erosion due to gravity. As shown at 10, the bottom surface B may be covered.

In the latter case, the bottom surface (B) of the vegetation hole (224, 234) is covered, it is possible to prevent the lack of vegetation soil due to the outflow of vegetation soil, and, in addition, the vegetation hole (224, 234) for smooth drainage The hole (D) may be formed in the covered bottom surface of the.

In the latter case, the bottom surface B of the vegetation holes 224 and 234 may be integrally formed with the surface block 210 on which the vegetation holes 224 and 234 are formed, as shown in FIG. 8. 9 and 10, at least one through-hole C penetrating in the vertical direction is formed in the surface block 210, and the vegetation holes 224 and 234 are covered with the through-hole C. The vegetation holes 224 and 234 as described above may be formed by inserting the pedestal D1 forming the bottom surface.

Here, as shown in FIG. 9, the pedestal D1 may protrude from the support jaw 210A so as to support the pedestal D1 in the through hole of the surface block 210. At this time, the pedestal (D1) is inserted in close contact with the inner surface of the through hole (C) of the surface block 210, in order to prevent the vegetation soil leakage, and the support jaw (210A) is a through hole of the surface block (210) It may be formed to protrude in a ring shape along the entire circumference of (C), or may be formed to protrude at least one like a projection.

Alternatively, as shown in FIG. 10, the through hole C of the surface block 210 may have a shape in which the cross section gradually narrows toward the lower side so that the pedestal D1 may be covered. That is, the pedestal D1 may be inserted into the through hole C of the surface block 210 and may span the surface block 210 by interference with the surface block 210. At this time, the circumferential surface D2 of the pedestal D1 corresponds to the inclined surface of the through hole C of the surface block 210 so that the pedestal D1 can be firmly coupled to the surface block 210. It is more preferable that the inclined surface is formed. In addition, the pedestal (D1) may be coupled to the surface block 210, such as bolt fastening in a variety of ways.

The pedestal D1 may be formed of the same material as the surface block 210 and may be formed of a different material from the surface block 210 as necessary. In the latter case, the surface block 210 is formed of a rigid material such as concrete for mechanical stability, and the pedestal may be formed of resin or wood material for cost reduction or another functional effect.

In addition, as the pedestal (D1) is removable, by selectively combining only the necessary surface block 210 of the plurality of surface blocks 210 forming the reinforcement earth retaining wall, regardless of whether or not the pedestal (D1) retaining wall retaining wall Since a plurality of surface blocks 210 forming the same may all be formed in the same shape, it may be more preferable in terms of manufacturability.

Here, the upper portion of the reinforcement soil retaining wall may be a problem of outflow of vegetated soil, but the lower portion of the reinforcement soil retaining wall may be filled by the vegetation soil leaked from the block constructed in the upper part of the reinforcement soil retaining wall even if the vegetation soil is leaked. It doesn't matter.

Accordingly, the surface block 210, that is, the basic block 220 and the auxiliary block 230 may be formed so that the bottom surfaces of the vegetation holes 224 and 234 are all covered. The holes 224 and 234 may be formed to penetrate, and only bottoms of the vegetation holes 224 and 234 may be formed so as to be constructed above the reinforcement soil.

In addition, the joint block 110 may be formed with the vegetation hole 114 like the surface block 210 described above.

Meanwhile, the joint block 110 and the surface block 210 may be supported by the reinforcement materials 300, 310, and 320 coupled to the anchor body (not shown) embedded in the rear soil sand 1.

At this time, the reinforcement 300, 310, 320 in the straight section of the reinforcement earth retaining wall may be constructed as follows.

First, as shown in FIGS. 4 to 7, the joint block 110 is not bound to the surface block 210 for expansion joints, but is solely a reinforcing material (hereinafter, for convenience of description, a 'only reinforcing material'). And 320). In addition, the surface block 210 is bound to the surface block 210 adjacent to the left and right in the left and right direction, the reinforcement (hereinafter referred to as "binding reinforcement (300, 310) for convenience of description). It can be supported by). At this time, except for the surface block 210 immediately adjacent to the joint block 110 in the left and right direction of the surface block 210 and the surface block 210 is constructed on the edge in the left and right direction, for one surface By fixing two binding reinforcement (300, 310) to the block 210 at the same time, the surface block 210 may be simultaneously bound in the left and right directions.

Second, as shown in FIG. 11, two binding reinforcements 300 and 310 may be fixed to both the joint block 110 and the surface block 210 at the same time. Therefore, the joint block 110 and the surface block 210 is more firmly bound in the left and right direction, it may be more preferable in terms of mechanical stability.

In addition, the reinforcement (300, 310, 320) in the curved section of the reinforced soil retaining wall may be constructed as follows.

First, as shown in FIGS. 4 to 7, the joint block 110 is supported by the sole reinforcement 320, and the surface block 210 is supported by the binding reinforcements 300 and 310. Can be.

In particular, one surface block 210 has a portion of a plurality of binding reinforcement (300, 310) is fixed, the other portion of the plurality of binding reinforcement (300, 310) is a surface adjacent to the left and right, respectively It may be settled in the dragon block 210.

Therefore, the surface block 210 may be firmly bound in both the left and right directions.

Second, as shown in FIGS. 12 to 17, the joint block 110 is supported by the sole reinforcement 320, and the surface block 210 is supported by the binding reinforcements 300 and 310. In addition, since the plurality of joint blocks 110 constructed in the vertical direction are bound to each other by the joint coupling member 330, mechanical stability may be increased.

At this time, the sole reinforcement 320 may be fixed to each of the plurality of joint blocks 110 constructed in the vertical direction, but the joint blocks 110 may be bound to each other by the joint coupling member 330. As shown in FIGS. 12 to 17, the sole reinforcement 320 is fixed to only some of the joint blocks 110 of the plurality of joint blocks 110 constructed in the vertical direction, thereby reducing work time and cost. It may be more preferable in terms of saving.

And, as shown in FIG. 14, all of the plurality of joint blocks 110 constructed in the vertical direction may be bound by one joint binding member 330, as shown in FIGS. 15 and 16. The plurality of joint blocks 110 constructed in the vertical direction may be divided and bound by the plurality of joint coupling members 330. In the latter case, when the plurality of joint blocks 110 constructed in the vertical direction as shown in FIG. 16 are inclinedly constructed, the joint block 110 constructed in the vertical direction also by the straight joint member 330 of the straight type. ) Can be easily bonded, which is preferable.

Third, as shown in FIGS. 17 and 18, the surface block 210 is supported by the binding reinforcement materials 300 and 310, and the surface block 210 and the joint block 110 are supported by the block binding member ( By binding by 340, both the joint block 110 and the surface block 210 can be more firmly bound in the left and right directions.

In addition, the joint block 110 may be further supported by the sole reinforcement 320 as necessary. In addition, the joint block 110 may be more firmly bound by the joint coupling member 330.

In this way, the joint block 110 and the surface block 210 are bound to the rearing soil 1 by the binding reinforcement members 300 and 310 and the sole reinforcement member 300, and are bound to each other in the left and right directions. Excessive displacement of the blocks (110, 210) is suppressed, cracks in the blocks (110, 210), gaps between the blocks (110, 210) and blocks (110, 210), consisting of blocks (110, 210) Since the filling phenomenon of the surface wall can be prevented, the effect that the mechanical stability is very excellent can be obtained. This effect can be fully applied to the straight section (refer to Figure 3) of the reinforced soil retaining wall, as well as bending, curved section (see Figure 12).

Here, the binding reinforcement (300, 310) is one joint block 110 or one surface block 210 to bind the joint block 110 or the surface block 210 in both the left and right directions. A plurality of fixing units may be fixed in one, and as shown, one joint block 110 or one surface block 210 may be bound together in the right and left directions with only two binding reinforcements 300 and 310. .

As described above, the binding reinforcement materials 300 and 310 are fixed to the joint block 110 and the surface block 210 like hooks, and then, before and after the joint block 110 or the surface block 210. The first reinforcing parts 302 and 312 fixed in the direction, the first reinforcing parts 302 and 312 to the blocks 110 and 210 and the adjacent blocks 110 and 210 to which the first fixing parts are fixed. Blocks 110 and 210 having the second reinforcing parts 304 and 314 bent from the reinforcing parts 302 and 312 and the first reinforcing parts 302 and 312 bent from the second reinforcing parts 304 and 314. It may be configured to include a third reinforcing portion (306, 316) is fixed to the adjacent block (110, 210) of the back and forth and coupled to the anchor body.

The first reinforcing portion (302. 312) of the binding reinforcement (300, 310) does not need to be combined with the anchor bar, the third reinforcing portion (306, 316) of the binding reinforcement (300, 310) for cost reduction Shorter formation may be more desirable.

The sole reinforcing material 320 is also a first reinforcing part 322 that is coupled to the anchor body and the other part is fixed to the joint block 110 in the front and rear direction in order to be firmly fixed to the joint block 110 like a hook. And a second reinforcing part 324 bent from the first reinforcing part 322 to be inserted and fixed to the joint block 110 in the vertical direction.

At this time, the second reinforcing portion 324 of the sole reinforcing material 320 may be bent from the first reinforcing portion 322 of the single reinforcing material 320 may be fixed in the left and right directions, as shown in FIGS. 13 and 18 As described above, in order to prevent interference with the joint binding member 330, it may be more preferable to be fixed in the vertical direction as shown.

The joint coupling member 330 is sufficient if it is possible to bind the plurality of joint blocks 110 in the vertical direction, so it is more preferable to be formed in a straight shape as shown, and if necessary, various shapes such as 'a' Of course it can be taken.
