The present invention relates to a retaining wall formed by stacking a plurality of blocks in a stepped manner. In particular, the retaining wall member block and the retaining wall having the same can be effectively secured in a plurality of blocks constituting the retaining wall. It is about.

As land use in river basins increases recently, various types of slopes are formed in rivers. Such slopes are likely to leak soil due to rainfall. When the soil is leaked, not only the river is polluted, but the flooding of the river causes problems such as flooding of farmland and houses.

In order to solve this problem, a stepped retaining wall is installed on a slope, and plants are planted at each end of the retaining wall. In this way, plants such as trees are planted on the retaining wall to prevent the outflow of soil on the slope, and the river is naturally purified by the planted plants. One example of such a stepped retaining wall is shown in FIG. 1.

Referring to Figure 1, a plurality of retaining wall blocks (1) (2) (3) (4) (5) are stacked in a step shape so as to prevent the outflow of soil on the slope of the river. Among the plurality of retaining wall blocks (1) (2) (3) (4) (5), three retaining wall blocks (1) (2) (3) of the upper side have soil (G) so that plants can be planted. In the lowermost fishery block 5 which is filled and submerged in the river, a fishery space 5a is formed in which fish can move and spawn. The fishery space 5a is filled with large gravel 7 so that fish can move or spawn to form large voids.

However, between the large gravel (6) is a small gravel (7) filled in the upper block (1) (2) (3) (4) or soil (G) or the soil (G) in the rear by the weight of the eoga space It is moved to 5a to fill in the voids formed between the large gravel 6 in the Associate Space 5a. In particular, since the compacting work is performed after filling the small gravel 7 or the soil G in each stage, the phenomenon in which the small gravel 7 or the soil G is filled in the air gap of the crew space 5a appears more prominently. . As such, when the air gaps of the fishery block 5 are filled with small gravel 7 or soil G, the fishery space 5a loses its function because a passage through which fishes are not formed is formed.

The present invention has been devised in view of the above-described points, and can adjust the size of the fishery space not only to secure the fishery space stably but also to secure the optimized fishery space according to the size of the river or the slope of the slope. It is an object to provide a retaining wall and a retaining wall having the same.

The purpose of the above-described retaining wall member block according to the present invention is to be submerged in a water retaining wall which is arranged on a slope with a plurality of blocks stacked on a slope, from a front wall and both ends of the front wall. A block body portion having a pair of side walls extending rearwardly; And a sediment inflow preventing member that cooperates with the front wall and the pair of side walls to form an association space, and prevents the effluent from entering the erosion space from above and behind the reciprocal space. The prevention member is provided to be movable in the front-rear direction between the pair of side walls so as to adjust the size of the associate space.

According to an embodiment of the present invention, the soil inflow preventing member forms an upper surface of the horn space, and an upper surface wall which prevents soil from above the horn space from flowing into the horn space; A rear wall extending downward from a rear end of the upper surface wall to form a rear surface of the food space, and preventing soil from behind the food space from flowing into the food space; And a pair of support walls extending from both ends of the top wall and the back wall to support the top wall and the back wall.

The pair of support walls are disposed between the pair of side walls, and the front wall forms the front surface of the associate space.

According to another embodiment of the present invention, the earth and sand inflow prevention member comprises: a curved wall for dispersing the pressure acting from the earth and sand of the upper and rear portions of the fishery space; And a support wall extending downward from both ends of the curved wall to support the curved wall, wherein the curved wall has a constant radius of curvature.

Meanwhile, an object as described above is a retaining wall formed by stacking a plurality of blocks in a stepped manner on an inclined ground, and having at least one or more of the plurality of blocks of the plurality of blocks. A block body portion having a pair of side walls extending rearward from an end; And a sediment inflow preventing member that cooperates with the front wall and the pair of side walls to form an association space, and prevents the effluent from entering the erosion space from above and behind the reciprocal space. The prevention member may also be achieved by a retaining wall, which is installed to be movable in the front-rear direction between the pair of side walls so as to adjust the size of the associate space.

It will be described below in detail with respect to the retaining wall for the retaining wall and the retaining wall having the same.

Referring to Figure 2, the retaining wall according to an embodiment of the present invention is installed in a stepped manner by stacking a plurality of blocks 10, 20, 30, 40, 50 on the slope of the river or lake. Vegetation parts 10a, 20a, 30a, which can plant plants, are formed in the three blocks 10, 20, 30 of the upper portion of the retaining wall, and the vegetation parts 10a, 20a, 30a are formed. Is filled with soil (G). And the fourth block 40 at the top of the retaining wall is filled with small gravel (6). Finally, the lowermost block 50 is a submerged block 50, which is composed of fishery blocks 50 which can spawn or inhabit as fish flow in and out.

The fishery block 50 is filled with large gravel 7 in which relatively large voids are formed so that a movement passage of fish can be formed therein. The Associate block 50 is pressured by the small weight of the small gravel (6) of the blocks 10, 20, 30, 40 or the soil (G) stacked on top, and due to this pressure small gravel ( 6) and the soil (G) is moved to the inside of the associate block (50). In particular, since the compaction work after the construction of each step in the construction of the retaining wall, the phenomenon that the small gravel (6) or soil (G) is introduced into the associate block 50 appears more clearly.

3 to 5, in order to prevent the small gravel 6 or the soil G from entering the associate block 50 and filling the voids, the associate block 50 may include a block main body 51. And, in cooperation with the block body portion 51 to form an eoeo space (50a) and to prevent the soil inflow prevention member to prevent the small gravel (6) or soil (G) to move to the eoseo space (50a) (60).

The block body 51 includes a front wall 52 and a left side wall 54 and a right side wall 55 extending rearward from both ends of the front wall 52. A plurality of moving through holes 53 are formed in the front wall 52 so that fish can flow into and out of the fishery space 50a therein. The left side wall 54 is formed with a semi-cylindrical protrusion 58 so as to be combined with an associative block arranged continuously on the left side. In addition, the right side wall 55 is formed with a semi-cylindrical groove 59 corresponding to the semi-cylindrical protrusion of the associate block disposed on the right side. On the other hand, the left side wall 54 and the right side wall 55 is formed with an activity preventing groove 57 is inserted into the activity preventing pin 56 for preventing the movement of the block 40 stacked on the upper side.

The soil inflow prevention member 60 is for preventing the small gravel 6 or the soil G, ie, the earth and sand, from entering the fishery space 50a as described above, and from above the fishery space 50a. An upper surface wall 61 for preventing soil from flowing in, a rear wall 62 for preventing soil from flowing from the rear of the associal space 50a, and an upper surface wall 61 and the rear wall ( A pair of support walls 64, 65 for supporting 62.

The pair of supporting walls 64 and 65 extend downward from both ends of the upper wall 61 and the rear wall 62, respectively, and are formed by the soil weight of the upper wall 61 and the rear surface. The load transmitted to the face wall 62 is transmitted to the ground.

The small-soil gravel 6 and the soil G are prevented from flowing from the upper portion or the rear portion to the fishery space 50a by the soil inflow preventing member 60 having such a structure. It is possible to prevent the voids formed by) from being filled by the small gravel 6 or the soil G, thereby effectively securing the Associate space 50a.

In addition, more than a certain number of large gravel 7 had to be filled in the Associate space 5a to support the existing up and down soil loads. Therefore, the control of the voids that can inhabit the fish in the fishery space 5a is determined only by the size of the large gravel, making it difficult to form an optimal fishery space. In addition, the soil inflow prevention member 60 can be moved in the front and rear directions according to the slope of the slope to adjust the size of the Associate space (50a), it is possible to further improve the freedom of design and construction. However, according to the present embodiment, by supporting the load of the upper and rear soils by the soil inflow prevention member 60, the number of large gravel 7 and the size of the voids which are filled in the inside space 50a are adjusted. It can be freely adjusted to create the optimal space for fish habitat.

On the other hand, in the present embodiment, the earth and sand inflow prevention member 60 is detachably coupled to the block main body portion 51 to form an associative space 50a. Therefore, the earth and sand inflow prevention member 60 may be installed in not only the lowermost block 50 but also the upper block 40 depending on the water depth, thereby securing the fishery space 50a. That is, it becomes possible to select the block for installing the soil inflow prevention member 60 according to the surrounding environment it is possible to improve the freedom of design and construction. However, unlike the present embodiment, the soil inflow preventing member 60 may be integrally formed with the block body 51.

6 and 7 are schematic diagrams of an associate block 50 according to another embodiment of the present invention.

6 and 7, the earth inflow prevention member 160 of the associate block 150 according to another embodiment of the present invention has a curved wall 161 unlike the embodiment of the present invention. That is, the upper wall 61 and the rear wall 62 in one embodiment of the present invention is replaced by the curved wall 161 in this embodiment.

As described above, when the Associate Space 150a is formed by the curved wall 161, the distribution of the load transmitted by the small weight of the small gravel 6 or the soil G can be made uniform. That is, in one embodiment of the present invention, the load may be concentrated on a part of the upper wall 61 and the rear wall 62, for example, an edge point where the upper wall 61 and the rear wall 62 meet. Therefore, in consideration of this, the material cost is relatively high because it must be designed to be reinforced. However, in the case of forming the curved wall 161 as in the present embodiment, the load is uniformly distributed throughout the curved wall 161 so that a constant strength can be maintained in a small amount of material. Meanwhile, the curved wall 161 is manufactured to have the same radius of curvature so that the load is more uniformly distributed.

According to the present invention described above, by preventing the inflow of small gravel or soil from the upper or rear to the fishery space by the soil inflow prevention member, it is possible to maintain the void formed by the large gravel of the fishery space, thereby A valid word space can be secured.

In addition, by installing the soil inlet prevention member to support the load of the upper and rear soils, it is possible to adjust the number of large gravel in the fishery space, thereby forming an optimal fishery space for the habitat of fish.

In addition, the sediment inflow prevention member is detachably coupled to the block body portion, it is possible to secure the earth space by installing the soil inflow prevention member in the upper blocks as well as the lowermost block depending on the depth. That is, according to the surrounding environment it is possible to freely select the block to install the soil intrusion prevention member can improve the degree of freedom of design and construction.

In addition, the soil inflow prevention member can be installed to be movable in the front and rear direction in the block body portion, it is possible to adjust the size of the Associate space according to the slope of the slope. As a result, the degree of freedom in design and construction can be further improved.

On the other hand, by forming the soil inflow prevention member to have a curved wall, the load is uniformly distributed throughout the curved wall, thereby reducing the input of the material for strength reinforcement, and eventually, the material cost can be reduced.
