Description

Reinforced earth retaining wall construction block {BLOCK FOR CONSTRUCTING RETAINING WALL}

The present invention relates to a block used to build a reinforcing soil retaining wall for building slopes such as embankments, breakwaters, coastal roads, etc. in preparation for the flow and collapse of soil, stones, and the like.

Reinforced earth retaining walls may be constructed in various forms and methods by concrete, masonry, bricks, and blocks made of stone or concrete, where the blocks are constructed horizontally and superimposed on one another in order to construct the reinforced earth retaining walls. Examples of the blocks used to construct the reinforcement soil retaining wall are known in various forms, one of which is disclosed in Korean Patent No. 116843 of Keystone Retaining Wall Systems.

A schematic structure of the 'wall block and wall structure' disclosed in Korean Patent No. 116843 is shown in FIGS. 1 to 3, which will be briefly described as follows.

As shown in FIG. 1, a conventional reinforced earth retaining wall construction block extends rearward from both ends of the front surface 1, the upper surface 2, the lower surface 3 and the front surface 1 having opposing ends. It has a block body (5) comprising side (4) 4 '. In addition, the reinforcement soil retaining wall building block is opened on any one of the upper surface 2 and the lower surface 3 of the block body 5 and has an arch shape (arc curved hole) spaced apart from the side surfaces 4 and 4 '. Has first and second pockets 6, 6 'and first and second pin holes 8, 8' for accommodating the pins 7). The first pinhole 8 is arranged adjacent to the first pocket 6 and is arranged laterally shifted therefrom, and the second pinhole 8 'is adjacent to the second pocket 6'. And arranged laterally from here. Here, the first and second pockets 6 and 6 'are formed to open to the upper surface 2 of the block body 5, and the first and second pin holes 8 and 8' are made to block. It is formed to penetrate the body 5 up and down. The lower end of the pin 7 protrudes downward from the block body 5 through the pin holes 8 and 8 '.

In the conventional block configured as described above, a plurality of blocks are constructed in a shape as shown in FIG. 2 to build the retaining wall, and the pins inserted into the pinholes 8 and 8 'of the upper block UB are the lower block DB. The coupling position of the upper and lower blocks UB (DB) is determined by being inserted into the pockets 6 and 6 'of the upper part, and at this time, the pin 7 moves upwards within the range of the pockets 6 and 6'. The coupling position of the block UB with respect to the lower block DB may be changed.

Accordingly, the conventional block provides an advantage that the retaining wall can be constructed by various construction methods in consideration of landscaping applications such as straight lines, concave and blocked curves, serpentine shapes, and circular shapes. For example, as shown in FIG. 3A, the upper block UB continues to contact the pin 7 of the upper block UB with the front end of the pockets 6 and 6 ′ of the lower block DB. By stacking, it is possible to construct a retaining wall in the form of an upright structure. As shown in FIG. 3B, when the pin 7 of the upper block UB is continuously stacked on the upper block UB so as to contact the rear end of the pockets 6 and 6 ′ of the lower block DB, the upper block UB is continuously stacked. Since the upper block UB is retracted and constructed as much as the length of the front and rear directions of the pockets 6 and 6 ', a stepped retraction is possible. In the same principle, the upper block is flexed by continuously stacking one pin of the upper block to the front of one pocket of the lower block and the other pin of the upper block to the rear end of the other pocket of the lower block. Retaining walls can be constructed that are built or curved.

However, since the shape of the pockets 6 and 6 'is formed in the forward and backward directions of the block in the form of an arc-shaped curved hole, the conventional reinforcement soil retaining wall construction block as described above is the pocket 6 and 6'. The pin 7 inserted in can flow back and forth in the pockets 6 and 6 '. Accordingly, there is no problem during upright construction (see FIG. 3A), in which the pin 7 of the upper block is in contact with the front end of the pockets 6, 6 ′ of the lower block when the retaining wall is constructed. Pins inserted into pockets 6 and 6 'during stepped retraction (see FIG. 3B) or when bending and bending are constructed so that (7) contacts the rear ends of pockets 6 and 6' of the lower block. By creating a free space (C) in front of (7), the upper block can be pushed by earth pressure, which makes it difficult to continuously maintain the appearance of the retaining wall in consideration of the landscaping constructed by the stepped retreat and curved constructions. There is a problem.

In addition, the retaining wall constructed by the conventional block has a state in which the pin 7 of the upper block UB is in contact with the wall surface of the pockets 6 and 6 'in the form of an arc-shaped curved hole of the lower block DB. The load by earth pressure is supported, but because the contact area is very small, the concentrated stress acts on the pin 7, and accordingly the wall surface of the pocket 6, 6 ′ in contact with the pin 7, etc. Problems may arise in terms of safety, such as cracks from.

4 and 5 show another example of a block for constructing a conventional reinforced earth retaining wall.

As shown in FIG. 4, the reinforcement soil retaining wall construction block according to another conventional example extends rearward from both ends of the front surface 11, the top surface 12, the bottom surface 13, and the front surface 11. Block body (15) comprising a side (14, 14 ') that is to be provided with a block interconnection means for connecting the upper and lower blocks to each other. The block interconnecting means is a pair of linearly slotted first and second pockets 16 formed along the X-axis direction of the block body 15 spaced inwardly from both side surfaces 14 and 14 '. 16 'and two pairs of first and second pin holes 18, 18' and 19, 19 'for receiving the pin 17. The pair of first pin holes 18, 18 'are formed spaced inwardly so as to be located on the same axis of the first and second pockets 16, 16', and another pair of the The second pinholes 19 and 19 'are formed at positions retracted to the rear side of the first pinholes 18 and 18' by a predetermined interval. In addition, the first and second pockets 16 and 16 'form a perforated opening penetrating the upper and lower portions of the block body 15, and two pairs of the first and second pin holes 18 and 18' ( 19 and 19 'form a closed opening which is only excavated from the upper surface of the block body 15 to a predetermined depth.

As described above, the reinforcement earth retaining wall construction block according to another conventional example forms the retaining wall by stacking the upper blocks alternately on top of the lower blocks arranged in a line like the above-described example, FIGS. 5A and 5B. As shown in Fig. 2, the pin 17 is fixed to one of the first and second pin holes 18, 18 '(19, 19') of the lower block DB so as to protrude to a predetermined height. The protruding portion of 17 is constructed in such a manner that it is inserted into the pockets 16 and 16 'of the upper block UB. At this time, as shown in Figure 5a, when the pin 17 is fixed to the first pin holes 18, 18 'of the lower block (DB), a retaining wall in the form of an upright construction can be constructed, as in Figure 5b As described above, when the pin 17 is fixed to the second pin holes 19 and 19 ′ of the lower block DB, a retaining wall in the form of a stepped retreat structure may be constructed.

Reinforcement earth retaining wall construction block according to another conventional example as described above is provided with a pocket-shaped pocket (16, 16 ') of a relatively narrow width in the front and rear direction formed along the X-axis direction of the block body (15). Therefore, since the pin 17 inserted into the pockets 16 and 16 'does not create a space enough to flow in the front-rear direction, the pockets 6 and 6' in the shape of the arc-shaped curved hole described above are Branch has the advantage that it is possible to prevent the sliding of the upper block due to earth pressure which has been raised as a problem in the block.

However, even in this case, since the upper and lower blocks are maintained in a state in which the upper and lower blocks are constructed by the connection structure between the pin 17 and the pockets 16 and 16 'with a small contact area, the stress concentration of the pin 17 mentioned above is maintained. The problem that cracks are generated from the weak wall surface of the pockets 16 and 16 'by the phenomenon is inevitable.

In addition, the aforementioned two types of reinforced earth retaining wall construction blocks have a structure using a geogrid as a means of binding the block to the backfill reinforcement soil when the retaining wall is constructed, the geogrid used as a block binding means has a weak tensile strength and elongation It is known that the deformation is large. Therefore, when the geogrid is used as a block binding means, the service life of the reinforced soil retaining wall can be abruptly shortened, such that the binding between blocks is weak so that the built state of the retaining wall can be easily deformed or collapsed even in small ground changes. In order to solve this problem, recently, a reinforcing material such as reinforcing bars having a tensile strength greater than that of the geogrid and having almost no elongation deformation is used as a block binding means. However, the above-mentioned conventional reinforcing soil retaining wall blocks are used as the block binding means as described above. The structure which can use a reinforcement is not provided, and improvement is calculated | required.

The present invention has been made in view of the above, and the upper block is not pushed by the earth pressure, so that the retaining wall shape originally constructed can be maintained as it is, and the contact area between the pin and the pocket is expanded to the earth pressure acting on the pin. It is an object of the present invention to provide a block for reinforcing soil retaining wall construction that can prevent various problems caused by concentrated stress, such as cracking of a block, by dispersing stress caused by the stress.

Another object of the present invention is to extend the service life of the retaining soil retaining wall by allowing a reinforcement such as a reinforcing bar, such as a reinforcing bar having a high tensile strength and little elongation strain, to the geogrid as a means of binding the block to the backfill reinforcement section. In addition, there is provided a reinforcement soil retaining wall construction block that can prevent the reinforcement soil retaining wall is easily deformed or collapsed due to changes in the ground.

The front surface 21 is formed in the form in which the inclined portion is extended to both sides of the straight portion, but the specific shape is not limited to the shape of the illustrated example, it is possible to appropriately change in consideration of aesthetics, such as to form an overall arc shape. In addition, although the detailed illustration is omitted on the front surface 21, various patterns may be designed. Both sides 24 and 24 ′ have a profile of a shape that is reduced toward the rear of the block body 20 and reaches a point to form a straight line and expand again therefrom. This is made in consideration of strength, material cost, and the like, and for the same reason, a vertical hole 25 penetrating up and down may be formed in a predetermined portion of the block body 20.

In addition, the block body 20 has a pair of elliptical pockets 26, 26 'formed at intervals inwardly from both side surfaces 24, 24' thereof, and both side surfaces 24 on the lower surface 23 thereof. It has a pin receiving groove 27 formed to cross the 24). The pair of oval pockets 26, 26 ′ are formed to face each other at regular intervals along the X-axis direction of the block body 20, and the pin receiving grooves 27 are formed on the bottom surface of the block body 20. 23 is formed to correspond to the position of the pair of elliptical pockets 26, 26 '. And, the pair of oval pockets 26, 26 'is preferably formed of a lower clogged opening that is dug to a predetermined depth from the upper surface 22 of the block body 20, the upper and lower surfaces of the block body 20 ( It may be formed as a lower open opening penetrating 22) and (23).

The block interconnection means 30 has a pair of elliptical connectors 31 and 31 'and connecting pins 32 and 32' protruding upward from the connectors 31 and 31 ', respectively.

The pair of elliptical connectors 31 and 31 'are inserted into and mounted in the pockets 26 and 26' with their outer circumferential surfaces in contact with the inner circumferential surfaces of the pair of elliptical pockets 26 and 26 '. . These connectors 31 and 31 ′ may be formed of concrete or plastic synthetic resin.

It can be fixed and installed by inserting one end thereof. The connecting pins 32 and 32 'may be formed of a metal material such as concrete, plastic resin, or iron or steel, but in view of strength, the connection pins 32 and 32' are preferably formed of a metal material such as iron or steel. Also, in the fixing of the connecting pins 32 and 32 ', a pin hole 31a is formed in the upper surface of the connecting holes 31 and 31' so that the metal connecting pins 32 and 32 'are inserted into and fixed thereto. This is preferable in view of strength. The protruding portions of the connecting pins 32 and 32 'are inserted into the pin receiving grooves 27 of the upper block UB, whereby the upper and lower blocks UB DB are connected. The connecting pins 32 and 32 'are eccentrically disposed so as to be biased toward either the front or the rear with respect to the center of the connector 31 and 31'.

Therefore, when the mounting positions for the pockets 26 and 26 'of the connectors 31 and 31' are mounted opposite to each other, the lower portion is provided with a length corresponding to the eccentricity of the connecting pins 32 and 32 '. The coupling position of the upper block UB with respect to the block DB can be changed, thereby enabling the block according to the present invention as well as a stepped retracting retaining wall construction.

In the retaining wall construction using the block according to the present invention configured as described above, as shown in FIG. 8, a plurality of lower blocks DB are arranged in a row, and a plurality of upper blocks UB are arranged in a row alternately thereon. The process is repeated. The connecting pins 32 and 32 'of the connector 31 and 31' mounted on the pockets 26 and 26 'of the lower block DB are the pins of the upper block UB. Each upper and lower blocks are constructed in the form of being inserted into the receiving groove (27). At this time, since the pin receiving groove 27 is formed long in a narrow form along the X-axis direction of the block body 20, the connecting pins 32 and 32 'in the pin receiving groove 27. There is no flow space in the front-rear direction, so that the upper block is not pushed by earth pressure. In addition, since the upper and lower blocks are connected and supported by the large-sized elliptical pockets 26 and 26 'and the connector 31 and 31', the stress applied to the connecting pins 32 and 32 'is dispersed. Therefore, it is possible to prevent a phenomenon in which stress is concentrated on the connecting pins 32 and 32 '.

It is formed across both side surfaces 324 and 324 ′, and the connector 331 inserted and mounted in the pocket 326 is also formed in one rectangle corresponding to the shape of the pocket 326. On the other hand, although not shown, in the present embodiment, the rectangular connector 331 may be divided into two around the pin holes 331a and 331a on both sides. Other configurations and actions are the same as the various embodiments described above. Therefore, the relevant reference numerals are given, and detailed description thereof will be omitted.

13 and 14 show a reinforcing soil retaining wall building block according to a fifth embodiment of the present invention, and a reinforcing soil retaining wall constructed by the block, respectively.

As shown in FIG. 13, the reinforcement earth retaining wall construction block according to the fifth embodiment of the present invention has the same basic structure as that of the reinforcement soil retaining wall construction block according to the first embodiment of the present invention. Therefore, in the following description, reference numerals associated with reference numerals in the drawings showing the first embodiment are cited.

As remarkable in the reinforcement soil retaining wall construction block according to the fifth embodiment of the present invention, as shown in FIG. 13, both sides of the neck portion 420c are formed on the upper surface of the neck portion 420c constituting the block body 420. Reinforcing member engaging groove 428 is formed to cross is provided.

As shown in Figure 14 when the retaining wall is constructed in the reinforcing member engaging groove 428, when the reinforcing member 500 such as reinforcing bars, such as reinforcing bars having a high tensile strength and almost no elongation strain, is used as a means for binding the block to the backfill reinforcement section. The reinforcement 500 is inserted and fixed. That is, in the existing blocks, structural weakness of the retaining wall may be exhibited by using geogrids having relatively low tensile strength and large elongation strain as block binding means, but in the block of the present invention, the reinforcement 500 as described above is blocked. Since it can be used as a binding means, the binding force between blocks can be strengthened, and a safe retaining wall can be constructed that does not collapse easily even when the ground changes. Furthermore, the retaining wall construction block of the present embodiment may use the existing geogrid and the reinforcement 500 together as a block binding means to construct the retaining wall. In this case, a safer retaining wall can be constructed. Here, the drawing shows an example in which the reinforcing member engaging groove 428 is formed on the upper surface of the neck portion 420c, but is not necessarily limited thereto, and the reinforcing member locking groove 428 is disposed on the lower surface of the neck portion 420c. It may be formed, or may be formed on both the upper and lower surfaces of the neck portion 420c.

One side of the reinforcing member engaging groove 428, more specifically, the surface on which the reinforcing member 500 is supported, the arc-shaped seating portion for increasing the contact area with the reinforcing member 500 and at the same time not to be easily separated 428a is formed. Accordingly, the reinforcement 500 inserted into the reinforcing member locking groove 428 while seated in the arc-shaped seating part 428a is not easily separated from the reinforcing member locking groove 428 even if the blocks move due to a change in the ground. Tightly bound.

On the other hand, the reinforcing member engaging groove 428, which is the main part of the block according to the fifth embodiment of the present invention as described above can be applied to the blocks according to the second, third and fourth embodiments of the present invention described above. Of course.

According to the present invention as described above, since the upper and lower blocks are constructed so that the connecting pin of the lower block is inserted so as not to flow into the narrow pin receiving groove of the upper block during the construction of the retaining wall, the blocks connected to each other are connected to the earth pressure. By this, the external shape of the retaining wall constructed by the stepped retreat construction method or the like can be maintained continuously, and the quality of the retaining wall can be improved.

In addition, according to the present invention, since the upper and lower blocks are supported in a state of being connected by an elliptical (or circular) pocket having a large contact area and a connector, the load acting on the connection part by earth pressure is dispersed without being concentrated in one place. Problems such as cracking of blocks due to stress concentration of the same pin can be solved, and a safer retaining wall can be constructed.

Further, according to the present invention, since the pin receiving groove into which the connection pin is inserted is formed to cross both sides of the block body, the connection pin to the pin receiving groove can be easily connected when the upper and lower blocks are constructed. This becomes very convenient.

In addition, according to the present invention, since the reinforcing member locking groove is formed in the neck portion of the block body, as a means for binding the block to the backfill reinforcement section when building the retaining wall, reinforcing materials such as reinforcing bars having a high tensile strength and almost no elongation deformation are unique. Can be used with or with geogrids. Therefore, the binding force between each block is strengthened, and the shape of the retaining wall is not easily deformed or collapsed even when the ground changes. As a result, the service life of the retaining wall can be extended.

On the other hand, while the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the above-described embodiment, the field to which the invention belongs without departing from the spirit of the invention claimed in the claims below. Of course, anyone skilled in the art can make various modifications, as well as such modifications are within the scope of the claims.
