The present invention relates to a retaining wall construction block, and in detail, depending on the installation site, it is possible to selectively build a gravitational construction or a reinforcement soil retaining wall, and vertically adjacent blocks are constructed in a mutually stacked manner, but the upper and lower blocks are separate. Without using subsidiary materials, the pneumatic coupling protrusions formed on both sides of the upper surface of the block and the through holes penetrated up and down inside the block are mutually interlocked to facilitate construction and form a more robust coupling structure. Combined in the form it is possible to build a retaining wall having a linear according to the terrain.

Generally, retaining walls constructed with blocks are classified into gravity retaining walls without reinforcement and reinforcement earth retaining walls using reinforcement. These retaining walls have different shapes and sizes depending on the construction method. There was a problem that the cost of manufacturing was not small because the molds and equipment for each were manufactured differently.In the gravity retaining wall, the block itself was too large and heavy, requiring a lot of manpower and equipment to be transported and constructed. In the retaining wall, various subsidiary materials, such as anchors and connecting pins, for connecting the blocks and the reinforcement embedded in the reinforcement soil and the coupling between the upper and lower blocks are required in large quantities, which complicates the construction cost and the construction process. This is being pointed out.

The present invention has been made in order to solve the above-mentioned conventional problems, the object of the present invention can be used both for gravity retaining wall or reinforced retaining wall retaining wall, retaining wall construction block that can build a lightweight and various linear retaining wall To provide.

In addition, the present invention can be interlocked with each other even without connecting pins between the upper and lower blocks, thereby reducing the need for auxiliary materials, eliminating the installation work of the auxiliary materials, improving workability, and directly connecting the reinforcement to the block. It can increase the binding force between the reinforcement and the block, diversify the connection structure between the block and the reinforcement according to the situation of the site, the vegetation of small animals and vegetation is possible on the built retaining wall itself, and the appearance of the built retaining wall It is relatively more beautiful than the existing retaining wall, and provides a retaining wall construction block having a sound absorbing effect when installed on the roadside where a lot of noise is generated due to traffic of a vehicle.

In order to achieve the above object, the present invention has a front surface forming a retaining wall and a rear surface, a left side, a right side surface, and an upper surface and a lower surface corresponding to the front surface, respectively. Middle portions of the left and right sides are formed with protrusions for coupling between adjacent blocks; A coupling protrusion for interlocking between blocks stacked up and down is formed on both sides of the rear part of the upper surface to be interlocked behind the through-holes of the blocks stacked on the upper part; It provides a retaining wall construction block having a structure in which the reinforcement insert groove is formed in the front and the inner side rear of the coupling protrusion.

The block according to the present invention can build a gravity retaining wall that does not use a reinforcement by the direct interlocking structure of the coupling protrusion and the through hole, or, if necessary, directly connect the front end of the reinforcement to the reinforcement insertion groove. In this way, it is possible to build an economical and easy-to-install prefabricated retaining wall without using any subsidiary materials.

Hereinafter, with reference to the accompanying drawings, preferred embodiments that do not limit the present invention will be described in detail.

1 to 4 illustrate the retaining wall building block B according to the present invention. The present invention includes a front surface 10 forming a retaining wall, a rear surface 20 corresponding to the front surface 10, a left side, In the retaining wall construction block having right side surfaces 30 and 40 and upper and lower surfaces 50 and 60 and a through hole 70 formed up and down inside, an intermediate portion of the left and right side surfaces 30 and 40 is provided. Protrusions 32 and 42 for joining between adjacent blocks are formed therein; Coupling protrusions 52 and 54 for interlocking between blocks stacked up and down are formed on both sides of the rear surface of the upper surface 50 so that the through holes 70 of the blocks on which the coupling protrusions 52 and 54 are stacked. Interlocked at the rear; Reinforcing member insertion groove (80, 82) is formed in the front and the inner rear of the engaging projection (52, 54).

Block (B) according to the present invention is preferably the dimensions of about 45 × 35 × 25cm each of the left and right width × front and rear width × top and bottom thickness, but the dimensions thereof can be arbitrarily changed, which is generally the existing small block and large It is about the middle size between the blocks, the weight is about 30 ~ 50kg, depending on the situation can be installed using both manpower or equipment.

The front surface 10 of the block (B) is formed by simultaneously forming a pair of blocks in the mold for molding to produce an atmosphere such as natural stone and cut by the split method so that the cut surface has a natural texture.

The left and right widths of the front surface 10 and the rear surface 20 are formed smaller than the left and right widths of the middle portion of the block (B) as shown in the plan view of FIG. As shown in FIGS. 3 and 4, the protrusions 32 and 42 formed on the left and right side surfaces 30 and 40 of the block B are adjacent to each other and the front surfaces 10 of the adjacent blocks are coupled to each other. The space S is formed while being spaced apart, thereby increasing the surface area of the retaining wall constructed by the block, and the space S is also in communication with the through hole 70 formed inside the lower block. S) and the through hole 70 may not only be used as a habitat for small animals, but when the soil is filled in the through hole 70 and plants are planted, the front surface of the retaining wall may be recorded. do.

As mentioned above, an increase in the surface area of the retaining wall by the space S has an advantage of reducing noise by, for example, effectively absorbing traffic noise of a vehicle.

The front surface constituting the through hole 70 of the block (B) is inclined backward toward the bottom, conversely, the inclined surface 72 is inclined forward toward the top, so that the through hole 70 when constructed as a vegetation retaining wall When the soil is filled in, the soil is not lost to the block below, and the vegetation planted in the soil grows toward the front upper part of the block, and is advantageous to extend into the space S between the upper blocks.

The front side (30, 40) of the block (B) may form a long narrow groove in the vertical direction so as to contrast with the aesthetics and the front surface (10), this groove provides a three-dimensional effect on the built retaining wall surface When the retaining wall is constructed by gravity type in riversides or cuts, it can provide favorable conditions for moss and various microorganisms to attach to this groove.

In addition, the rear side of the block (30, 40) is formed so that the width becomes narrower toward the rear, so that a small space is formed between the rear of the side block (30, 40) of the adjacent block so that the empty space of the retaining wall After the construction is completed, the earth pressure can partially absorb the concentrated transfer to the back side of the block to have the earth pressure reduction effect on the retaining wall, or by filling the space in this space, the soil and the block can be combined three-dimensionally. In addition, it will be described in detail later, but to enable the installation of the reinforcement embedded in the reinforcement body through this space.

When the soil is filled in the space formed between the rear side of the adjacent block (30, 40), it is possible to prevent the reinforcement soil to flow out of the front of the block by rolling a small drain filter made of a non-woven fabric, etc. desirable.

In addition, the reinforcement soil 90 is lost to the front of the retaining wall together with water through the gap between the blocks by laying the reinforcement soil in the state in which the drainage filter 130 is installed vertically every two layers on the rear surface 20 of the block. To prevent it.

The upper surface 50 and the lower surface 60 of the block are basically formed to form the same plane, but the coupling protrusions 52 and 54 for interlocking between blocks stacked up and down are formed on both rear sides of the upper surface 50. It is projected upward by about 1.5cm.

The coupling protrusions 52 and 54 generally have an elliptical shape, and the coupling protrusions 52 and 54 of the through hole 70 formed in the inner side of the block constructed thereon as shown in FIGS. 3 and 4. It is fitted to the rear part and interlocked in the vertical direction.

The engaging projections 52 and 54 of both sides of the block form a symmetrical shape, respectively, in which the rear end portions 52a and 54a of the inner side abut the edges of the rear end portions of the through holes 70 and the outer end portions 52b and 54b, respectively. Is located in front of the rear ends 52a and 54a of the inner side, and coupling protrusions 52 and 54 are formed in a diagonal direction.

In addition, the reinforcing member insertion grooves 80 and 82 are formed to a depth of about 3 cm in front of the inner and rear portions of the engaging projections 52 and 54, so that the engaging projections 52 and 54 adjacent to the front ends of the reinforcing members are common. It is an anchor of and can be connected in a semicircle, wrapped around it.

The block according to the present invention has a symmetrical shape as in the conventional retaining wall construction block, except that only the protrusions 32 and 42 formed on the side surfaces 30 and 40 are slightly staggered to form asymmetry.

On the other hand, in the front center portion of the upper surface 50, the auxiliary projection 56 is the same height as the engaging projections 52, 54 formed on both sides of the rear surface of the upper surface in order to be able to stack the multi-stage stack in the horizontal state when transporting the block Formed.

The auxiliary protrusion 56 does not touch the upper block because the upper and lower blocks are built alternately when the retaining wall is built, and only the engaging protrusions 52 and 54 formed at both rear sides of the lower block are located below the through hole 70 of the upper block. Interlocked at
