The present invention relates to a reinforcing soil retaining wall, and more particularly, by extending an arm behind a laminated structured block and allowing a pile fitted to an end of the arm to be embedded in the soil of the retaining wall construction paper. The present invention relates to a block assembly for reinforcing soil retaining wall construction, which can be prevented from being pushed by earth pressure to maintain a solid retaining wall.

In general, a reinforced soil retaining wall is a wall that is constructed on an inclined surface, i.e., a slope of a river or a dike, to resist soil pressure so that the slope does not collapse.

Such a reinforcement earth retaining wall is constructed in various forms, Figure 1 shows the most commonly constructed reinforcement earth retaining wall (1), the back of the block (2) while the plurality of blocks (2) are stacked in a multi-stacked manner Soil (reinforced soil 3) is constructed by chopping.

However, the construction method of the reinforcement soil retaining wall is because the stacked blocks (2) are simply stacked in a surface contact state, so that the block is prevented by external earth pressure due to earth pressure generated when the backfill soil is compacted and rainwater is submerged in the ground after construction. There was a drawback of the phenomenon that it could not maintain a solid retaining wall condition.

In order to solve this problem, recently, a block 4 having a protrusion 4a protruding from the upper surface of FIG.

However, such a construction method should be stacked in a state in which the protrusions 4a are accommodated in the space of the block 4 on which the protrusions 4a are stacked when stacking a series of other blocks 4 on the protrusions 4a. Since the inclination angle of the retaining wall cannot be arbitrarily adjusted, there is a disadvantage that construction is impossible when the incision is steeply inclined or gently inclined.

Accordingly, the present invention is to solve the problems of the conventional retaining wall as described above, the object is to provide a block assembly for reinforcing soil retaining wall construction to maintain a solid retaining wall so that the block is not pushed by the earth pressure.

Reinforcement earth retaining wall construction block assembly for achieving this purpose, has at least one or more planting space portion therein, the projection protrudes on one side of the body to be fitted and accommodated the projection on the other side facing the projection Receiving groove is concave in the shape that can be formed, the wings protruding on both sides of the rear and stacked blocks stacked on the retaining wall shaft paper; An arm having a rod-shaped body having a fitting hole formed at a rear end thereof, and having a front end fixed to the rear of the block; And a pile fitted to the fitting hole of the arm and embedded in the earth and sand of the retaining wall shaft paper to prevent the block from being pushed forward by the earth pressure.

Hereinafter, based on the accompanying drawings will be described in detail a block assembly for reinforcing soil retaining wall construction.

And, Figure 7 is a detailed view showing an enlarged portion of the bolt is fastened to the block according to the present invention, Figure 8 is a detailed view showing a state in which the pile according to the present invention is fitted to the bolt, Figure 9 is in accordance with the present invention Assembly plan view of blocks assembled in a curved form.

* As shown in the drawings, the reinforcement soil retaining wall construction block 11 assembly 10 according to the present invention includes a block 11 stacked on the retaining wall construction paper, and an arm fixed and extended to the rear of the block 11. (12), and a pile (Pile. 13) fitted to the arm (12) and embedded in the soil of the retaining wall shaft support to prevent the block (11) from being pushed forward by earth pressure.

The block 11 has a planting space portion 11a to plant trees therein, and a protrusion on one side of the body so that the block 11 can be assembled to be fitted with each other with the neighboring blocks 11. 11b) protrudes and the receiving groove 11c is recessed in a shape that can accommodate the protrusion 11b on the other side opposite to the protrusion 11b.

The planting space portion 11a of the block 11 is formed on both sides of the central partition wall 11e, and the planting space portion 11a formed at the rear of the body communicates with the fastening hole 11d so that the nut N ) Accepts the nut (N) when fastening the arm (12).

In addition, the block 11 penetrates the fastening hole 11d to fix the arm 12 to the rear of the body.

In addition, the block 11 has wings 11f protruding from both rear sides thereof, and the blades 11f are in contact with each other when the blades 11f are fitted with the neighboring block 11 to block 11. Function to prevent the flow of.

Here, the blade 11f of the block 11 is configured to adjust the length so that the blade 11f of the block 11 located on both sides than the blade 11f of the block 11 located in the center as shown in FIG. Shorter it allows the retaining wall to be constructed in a curved shape.

Therefore, guide grooves 11g for guiding cutting are recessed in both longitudinal side surfaces of the blades 11f so as to adjust the length by cutting the blades 11f, preferably a plurality of guide grooves 11g are arranged in a row. It is good to be formed.

The block 11 configured as described above is preferably such that its own weight is at least 300 kg to withstand earth pressure with its own weight. For reference, since the weight of the conventional retaining wall block is only 40 to 100 kg, the weight alone could not withstand the earth pressure. Thus, if the weight of the block 11 is 300kg or more, and the block 11 is constructed in a stacked manner to form the retaining wall, the block 11 can withstand a certain amount of earth pressure even with its own weight, and the pile 13 It is fixed to) to maintain a solid retaining wall.

Blocks 11 configured as described above are stacked in a stacking type in a state in which a plurality of blocks are assembled to fit each other by a protrusion (11b) and the receiving groove (11c) formed on both sides of the body as shown in Figure 5 to 6 It will form a retaining wall.

The arm 12 is inserted into the fastening hole 11d formed at the rear of the block 11 as shown in FIG. 7 and fastened and fastened by the nut N. As shown in FIG. The arm 12 fixed in this way has a threaded portion 12a formed at the front end thereof to be fastened to the nut N, and has a ring-shaped fitting hole 12b for accommodating the pile 13 at the rear end thereof.

Since the length of the arm 12 can effectively prevent the block 11 from being pushed away as the pile 13 moves away from the block 11, the longer the better, and in practice, the length of the arm 12 cannot be infinitely long. 500cm is good.

The arm 12 is preferably made of metal, preferably steel.

In the case of using the steel as described above, it is preferable that the steel is plated with a material that is not oxidized to prevent corrosion because the steel is embedded in the soil of the tank and easily corroded.

The pile 13 is inserted into the fitting hole 12b of the arm 12 and embedded in the earth and sand of the shaft paper, and serves to prevent the block 11 from being pushed forward by earth pressure. . Such a pile 13 preferably has a shape of large frictional resistance, and for this purpose, a large and wide one is preferable.

Next, a process of constructing the retaining wall using the block assembly 10 for reinforcing soil retaining wall construction according to the present invention will be described.

First, the ground of the retaining wall shaft paper is evenly arranged, and then a plurality of blocks 11 are assembled and arranged by fitting using the protrusions 11b and the receiving grooves 11c on the ground.

After that, the reinforcing soil is filled in the incision behind the block (11).

After the reinforcing soil is chopped as described above, the threaded portion 12a of the arm 12 is inserted into the rear fastening hole 11d of the block 11 and fastened and fastened with a nut N. The arm 12 thus extends rearward while being fixed to the block 11.

In this way, the pile 13 is inserted into the fitting hole 12b of the arm 12 fixed to the block 11 and then inserted into the ground of the shaft paper to complete the arrangement of the blocks 11.

Subsequently, in the same manner as described above, one end of the blocks 11 are arranged in a multi-stacked manner on the arranged blocks 11, and the pre-placed piles 13 are filled by filling reinforcement soil in the rear incisions. The retaining wall is constructed by stacking the blocks 11.

As such, the arm 12 is selectively fixed to the rear of the blocks 11 in the process of constructing the block 11 so that the arms 12 extend at regular intervals.

For example, if there are 30 blocks 11 in a row, one arm 12 may be fixed to every five blocks 11 to fix the six arms 12 to the block 11 at regular intervals. At this time, the stacked upper and lower arms 12 may be alternately arranged, that is, arranged in a zigzag fashion in the vertical direction.

Preferably, the arm 12 is connected to the block 11 of the diaphragm, and the arm 12 is connected to the one block 11 for every two blocks 11 of the end layer.

On the other hand, when the retaining wall is constructed in a curved shape due to the nature of the terrain, a tool is applied to the guide groove 11g of the block 11 to impart a wing 11f along the guide groove 11g as shown in FIG. 9. Cut to shorter length. In this way, when the length of the blade 11f is shortened, the fitted and assembled block 11 can build a smooth curved retaining wall in the form where the central portion protrudes.

The retaining wall constructed by this construction method is not only heavy but its arm extends to the rear of the block, and the pile is inserted and embedded in the fitting hole of the arm, so that the block is prevented even if earth pressure is generated by the resistance of the arm and the pile. It is not easily pushed away, and especially when the pile is buried directly inside the incision surface instead of the reinforcement soil, the block is prevented from being pushed forward, thereby maintaining a strong retaining wall.
