Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a block for a retaining wall formed by a synthetic resin,

The present invention relates to a block for a retaining wall formed by a synthetic resin and a method for constructing a retaining wall using the same, more specifically, it can be formed into various shapes and colors by using a synthetic resin, and is light in weight compared to a concrete block, And a method of constructing a retaining wall using the same.

Generally, the retaining wall is a civil structure that is constructed to support the slope of the slope by supporting the slope of the back surface to construct roads, railways, industrial complexes, etc. in the ground.

These retaining walls are constructed in consideration of the geographical conditions and factors acting on the retaining walls after the retaining walls are constructed. Traditionally, it is necessary to cut the gravels in the construction area or to form molds to fill the valleys and low areas in the mountains, Block retaining walls have been widely used to build concrete lining walls or concrete blocks built in the factory in the form of laminates on the back side of the concrete structure by pouring and curing the concrete.

The concrete retaining walls effectively prevent the collapse of the ground due to the rigidity of the material and the weight of the concrete itself. However, the concrete retaining wall can not avoid the possibility that the vegetation grows in consideration of the stability of the slope, so that it is impossible to avoid the heterogeneous scenery that does not match with the surrounding environment, and there is a problem that the animal habitat disappears and the natural ecosystem is destroyed. Particularly, the retaining wall vertically stacked on the shore or at the foot of the mountain has the problem that the animal can not cross the retaining wall, blocking the moving path, isolating or breaking the animal ecosystem.

In recent years, the construction of retaining walls which are conscious of such environmental problems and laminated ecological concrete blocks in harmony with the surrounding landscape has been actively carried out. The block retaining wall is constructed by pouring the concrete and installing the foundation concrete layer in advance. The block retaining wall is made up of a block made of concrete which prevents the soil from being pushed forward by forming a front wall, a nonwoven fabric and a backing material provided on the rear side of the block, and an appropriate anchor means. It is a common practice to fill the backside of stacked blocks with backfill material such as crushed stone.

A block for constructing a retaining wall is proposed in Korean Patent Registration No. 10-0458901, which is a block for constructing a retaining wall for reinforcing earth which facilitates joining between blocks using reinforcing projections. Also, a 'block for building a reinforced earth retaining wall' (Korean Patent Registration No. 10-0392590) has been filed for reinforcing the structural bonding using reinforcing members such as reinforcing bars and preventing the upper block from being pushed by the earth pressure.

The conventional concrete convex as described above has an advantage of high strength, but it has a problem that the risk of collapse due to cracking due to pressure or corrosion is increased due to the characteristics of the material. Also, it is not easy to handle and transport because of its heavy weight, and since the block must be lifted by using heavy equipment during construction, construction is complicated and takes a lot of time and there is a fear of safety accident.

In addition, due to the nature of the concrete material, it is not possible to produce colors and it is difficult to form various shapes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a block for a retaining wall formed of a synthetic resin according to a preferred embodiment of the present invention and a method for constructing a retaining wall using the same will be described in detail with reference to the accompanying drawings.

1 to 5, a retaining wall block according to an embodiment of the present invention includes a main body 10 formed of a synthetic resin, a first aggregate containing portion 20 formed on the inner side of the main body 10, A concrete charging part 30 provided on the main body 10 and surrounding the first and second aggregate receiving parts 20 and 25 so as to surround the first and second aggregate receiving parts 20 and 25; And a connecting groove 40 formed in a long direction.

The main body 10 is formed of a synthetic resin. The synthetic resin can be melted and extruded or extruded by the molding method.

When the main body 10 is manufactured using a synthetic resin, it can be formed into various shapes. In addition, since the body 10 can be made in various colors, it is possible to manufacture a color block. In addition, synthetic resin is much lighter in weight than concrete, so it is easy to handle and transport. Also, it does not require heavy equipment for lifting the block at the time of construction, so construction is simple and fast.

Polyethylene, polyproplene, polyethylene terephthalate, synthetic rubber, or the like can be used as the synthetic resin that can be used for forming the main body 10. Preferably, as the main body 10 is elastically deformable, a soft resin or an elastomeric material can be used.

The main body 10 is formed in such a shape that the front side width is larger than the rear side width. In the right and left portions of the front surface of the main body 10, corrugated irregularities 13 are formed.

On the inner side of the main body 10, first and second aggregate containing portions 20 and 25 are formed.

The first aggregate receiving portion 20 is provided with a first receiving space 23 formed to pass through the main body 10 in the vertical direction. The second aggregate receiving portion 25 is formed at a position spaced rearward from the first aggregate receiving portion 20. The second aggregate receiving portion 25 is also provided with a second receiving space 27 formed so as to pass through the main body 10 in the vertical direction.

The weight of the main body 10 can be reduced by the first and second aggregate receiving portions 20 and 25 and at the time of constructing the retaining wall as shown in FIG. 27 are filled with the aggregate 1 to secure the weight of the block. Sand, gravel, crushed stone, and the like can be used as the aggregate 1 that can be filled in the first and second accommodating spaces 23 and 27. It is needless to say that it is possible to fill the soil instead of the aggregate if necessary. In this case, soil can be used alone or mixed with aggregate.

A concrete filling portion 30 is formed around the first and second aggregate receiving portions 20 and 25. That is, the first and second aggregate receiving portions 20 and 25 are located inside the concrete filling portion 30. As shown in FIG. And the concrete charging part 30 surrounds the first and second aggregate receiving parts 20 and 25 from the outside.

In the illustrated example, the concrete charging part 30 is formed in the shape of a trapezoid in the vicinity of the edge of the main body 10 as a whole. The concrete charging part 30 is formed as a groove drawn at a certain depth from the upper surface of the main body 10. The depth of the concrete filled portion 30 may be about 5/10 to 9/10 of the height of the body 10. [ At the time of constructing the retaining wall, concrete 5 is poured into the concrete charging part 30 to fill it.

A connecting groove 40 is formed in the main body 10. The connection groove 40 is formed by a groove formed at a predetermined depth from the upper surface of the main body 10. The connecting grout portion 40 is formed to be shallower than the concrete filling portion 30. [ The connecting groove 40 is elongated from one side of the main body 10 toward the other side. In the illustrated example, the connecting groove 40 is formed in a long straight shape from the left side to the right side of the main body 10. [ Thus, the connecting groove 40 intersects with the concrete filling portion 30 formed in the main body 10. And are interconnected at points that intersect the connection groove 40 and the concrete charging portion 30. [

The connecting groove 40 is formed to pass between the first aggregate receiving portion 20 and the second aggregate receiving portion 25. At the time of constructing the retaining wall, concrete 5 is poured into the connecting groove 40 to fill it. In this case, since the connection groove 40 and the concrete charging part 30 are connected to each other, the concrete poured into the connection groove 40 and the concrete poured into the concrete charging part 30 are also connected to each other after curing.

A joint portion (50) is formed on one side of the main body (10). Two or more convex connecting grooves 40 are connected to each other by the joint portion 50. [

The joint portion 50 is formed to protrude from one side of the main body 10 and is coupled to a side surface of an adjacent block. The joint portion 50 is formed on the side surface of the main body 10 so as to coincide with the direction in which the connecting groove 40 extends.

The joint portion (50) is formed with an extension groove (55) at a certain depth on the inner side. The extending groove 55 is connected to the connecting groove 40. Therefore, the joint portion 50 serves to extend the connecting groove 40 in the outward direction of the main body 10.

As shown in FIG. 5, the ends of the joint part 50 are formed to abut the side surfaces of the adjacent blocks to connect the connection grooves 40 between the blocks. When the concrete groove 5 is filled in the connecting groove 40, the concrete is also filled in the extending groove 55 of the joint portion 50. Therefore, the joint grooves 40 between the respective blocks can be integrated by the joint portion 50.

The end of the joint portion 50 is formed in an appropriate shape according to the shape of the main body 10. [

The present invention may further comprise a vertically coupling means for coupling the main body 10 in the vertical direction.

The upper and lower coupling means includes at least two insertion grooves 60 formed at the upper portion of the main body 10 and a wedge portion 70 formed at the lower portion of the main body 10 and adapted to be coupled to the insertion groove 60, Respectively.

The insertion groove 60 is formed as a circular groove having a constant depth. Three insertion grooves 60 are formed on the left and right sides of the upper surface of the main body 10, respectively.

The wedge portion (70) is formed at the bottom of the body (10). The wedge portions 70 are formed on the left and right sides of the bottom surface of the main body 10, one by one. The wedge portion 70 is formed at a position corresponding to the insertion groove located at the center among the three insertion grooves 60.

The wedge portion 70 includes a body portion 71 protruding from the bottom surface of the main body 10, a conical tip portion 73 formed at an end portion of the body portion 71, And a deformed portion 75 which is deformed when the protrusion is inserted into the insertion groove 60 and is brought into close contact with the insertion groove 60.

The outer diameter of the deformation portion 75 is formed to be larger than the inner diameter of the insertion groove 60 so that when the insertion groove 60 is drawn into the insertion groove 60, the edge of the deformation portion 75 is closely contacted with the insertion groove 60,

The wedge part is inserted into the insertion groove formed in the lower block when the block is stacked up and down.

Hereinafter, a retaining wall construction method using the above-described blocks will be described with reference to FIGS. 6 and 7. FIG.

A plurality of blocks 100 are arranged on the base surface and are arranged adjacent to each other in the left and right direction to stack one stage. At this time, the ends of the joint portion 50 are formed to abut the side surfaces of the adjacent blocks, and the connecting grooves 40 between the blocks are connected in a straight line.

Since the block 100 applied to the present invention is formed of synthetic resin and is light in weight, it is possible to lift and set the block by hand only without the help of heavy equipment. The first and second receiving spaces 23 and 27 formed in the respective blocks 100 are filled with the aggregate 1.

Next, the concrete 5 is poured into the concrete charging part 30 formed in each of the blocks 100 to fill the concrete charging part 30 with the concrete 5.

Next, concrete is poured into the connecting grooves 40 to connect the connecting grooves 40 of each of the blocks 100 to the concrete. When the concrete groove 5 is filled in the connecting groove 40, the concrete is also filled in the extending groove 55 of the joint portion 50.

After the first stage is constructed as described above, the filler 7 is filled in the empty space between the block 100 and the cutout.

When the first stage is constructed, the second stage is stacked on it. The two-stage block is disposed at a boundary between the first-stage blocks. The wedge portion 70 of the second-stage block 100 is inserted and engaged with the insertion groove 60 of the first-stage block.

When the upper and lower blocks are connected to each other, the aggregate is filled in each of the two-stage block, and then the concrete is poured and charged.

After the second stage is completed, fill the empty space between the block and the cutout with the filling material. And three or more stages are laminated on the two stages to form a retaining wall.

When the retaining wall is constructed, a nonwoven fabric may be installed on the rear side of the block, or the block and the cutter may be connected by an appropriate anchor means.

Figs. 8 and 9 show the retaining wall different from the above-described example in the lamination method.

Referring to FIGS. 8 and 9, as the first layer is stacked, the second layer is formed so as to be retracted rearward by a predetermined distance. For example, the wedge portion 70 of the block 100 constructed in the second stage is retracted by a position inserted into the concrete filled portion 30 of the block constructed in the first stage.

FIG. 10 shows a block for a retaining wall according to another embodiment of the present invention.

Referring to FIG. 10, a coupling protrusion 200 is formed on one side of the main body 10 and a coupling groove 210 is formed on the other side. Therefore, as shown in FIG. 11, when engaging the retaining wall blocks, the engaging protrusions and the engaging grooves can be coupled to each other between adjacent retaining wall blocks. The retaining wall blocks shown in Figs. 10 and 11 are the same as those in Fig. 1, so that the description of the remaining constitution will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
