Description

Band type reinforcing member and reinforcing member assembly having this}

The present invention relates to a strip-shaped reinforcement, and more particularly, to a strip-shaped reinforcement and reinforcement assembly for reinforcing the tensile strength of the ground by fixing one end to a reinforcing block and the other end installed on the backfill.

A block-type retaining wall structure formed by stacking a plurality of blocks is constructed to prevent soil from flowing down and collapsing in a levee or hillside. In such a reinforced soil retaining wall, a reinforcement material that generally combines the retaining wall block and the backfilling soil (reinforcement soil body) is sometimes used.

As a type of reinforcement, there is a geogrid in the form of a net, and recently, a band-shaped reinforcement that is installed in a zigzag shape on the backfilling soil is used while being inserted into the fitting groove formed on the upper surface of the retaining wall blocks prefabricated in the front of the reinforced soil retaining wall. have.

In other words, to reinforce the tensile strength of the ground in the stacked block, a band-shaped fiber reinforcement is combined and installed.This fiber reinforcement is fixed at one end to the block using anchors or anchor pins, and the other end is buried in the ground for a long time. Therefore, it resists external forces such as earth pressure by reinforcing the reinforced soil body by using the frictional force generated on the contact surface with the ground.

When using such a strip-shaped fiber reinforcement to support the block forming the retaining wall, the end of the strip-shaped fiber reinforcement is hung on a connecting ring protruding from the back of the block, and is fixed to the front of the supporting wall spaced from the rear of the block. The other end of the band-shaped fiber reinforcement material, which has one end on the connecting ring, is hung on the support rod and continuously laid in a zigzag manner, and then reinforcing soil is filled between the block and the support wall to form a retaining wall structure.

However, such a fiber reinforcement material lacks frictional resistance with the soil, and thus the length of the reinforcement material is increased more than necessary during stability review. Of course, it is also possible to improve the frictional resistance by increasing the length of the fiber reinforcement, but this has a disadvantage in terms of constructability and economy by increasing the amount of backfilling.

And, in the process of installing the strip-shaped reinforcement in a zigzag manner, the direction of the strip-shaped reinforcement is changed.If the strip-shaped reinforcement has a direction, there is a problem in that construction convenience is deteriorated because it must be constructed while considering the direction of the strip-shaped reinforcement.

In addition, as a method for fixing the fiber reinforcement, a technique is used in which the fiber reinforcement is wound between blocks constituting the retaining wall and is pressed against the weight of the block. There was also a problem of reducing.

In order to compensate for these shortcomings, steel, which is a non-extensible material, is sometimes used as a reinforcing material. A reinforcement made of steel increases the frictional resistance by installing a passive resistance body at the rear end thereof, and due to the characteristics of the steel, it has an advantage in passive resistance performance compared to the fiber reinforcement. However, metal reinforcing materials such as steel have a problem in that the material cost is significantly increased, and workability is relatively inferior, such as a passive resistor must be installed.

In addition, pockets protruding from the upper and lower surfaces of the strip-shaped reinforcement material to generate resistance force were placed, and the pockets were formed to penetrate through the opposite side of the strip-shaped reinforcement material. However, there is a problem in that the pockets formed by protruding from the upper and lower surfaces of the belt-shaped reinforcing material are opened toward opposite surfaces, respectively, so that the reinforcing soil body passes through them, thereby relatively reducing frictional force.

The belt-shaped reinforcement 100 according to the present invention is located in the backfill soil (B) and serves to reduce the pressure of the backfill soil (B) to change horizontally through friction with the backfill soil (B). In other words, by the friction between the backfill soil (B) and the strip-shaped reinforcing material 100, the adhesive strength and the internal friction angle of the backfill soil (B) are enhanced, and accordingly, the shear strength of the backfill soil (B) is improved, resulting in a solid reinforcing soil. To do it. The belt-shaped reinforcement 100 according to the present invention may be installed while forming a plurality of layers on the backfilling soil (B), and more detailed information will be described again below.

The strip-shaped reinforcement material 100 is formed in a thin strip shape, and is basically made of a flexible material. In this embodiment, the band-shaped reinforcing material 100 is made of a synthetic resin material, but is not limited thereto. For example, the band-shaped reinforcing material 100 may be made of a polymer material, and may be composed of a high-strength polyester fiber or a polyethylene coating covered thereon.

The band-shaped reinforcement member 100 may be extended in one direction and installed in a zigzag form inside the backfilling soil B, and a part of the band-shaped reinforcement member 100 is connected to and fixed to an installation block 200 to be described later. It can be seen that the band-shaped reinforcement member 100 is partially fixed to the installation block 200 and the direction in which it extends relative to the installation block 200 changes.

1 to 3 shows an embodiment of a band-shaped reinforcement (100). As can be seen, the band-shaped reinforcement member 100 is elongated in one direction, and a part thereof is shown in FIG. 1. The strip base 102 forms the exterior and the skeleton of the strip-shaped reinforcement material 100, and the strip base 102 is made of a flexible material. The strip base 102 has a strip shape having a length and a thin thickness compared to the width.

The strip base 102 is elongated in one direction and may be divided into a base body 110 and a resistance body 120. Here, the base body 110 refers to a portion of the strip base 102 where the resistance jaw 170 is not provided, and the resistance body 120 can be viewed as a portion with the resistance jaw 170. In this embodiment, the base body 110 is formed to extend along both ends and the center in the width direction of the strip base 102, and the resistance body 150 is parallel to the base body 110 between the strip base 102. It is extended and provided. Reference numeral 110' denotes a base body provided between the resistance body 120 as a part of the base body 110.

As shown in Figure 2, the inside of the base body 110 is provided with a reinforcing means (130). The reinforcing means 130 is for supplementing the strength of the strip base 102 and thus reinforcing the strength of the entire band-shaped reinforcing material 100. The reinforcing means 130 is inserted into the base body 110, and in this embodiment, it is made of polyester. More precisely, the reinforcing means 130 of the base body 110 is made of a polyester material, and its outer surface is made by coating with LDPE. Of course, the reinforcing means 130 and the material of the base body 110 surrounding the reinforcing means 130 can be variously modified.

In this embodiment, the reinforcing means 130 is configured as a pair, and these are provided inside the base body 110 in a partitioned state. As shown in FIG. 2, a pair of the reinforcing means 130 are provided inside the base body 110, respectively, and the number of reinforcing means 130 increases as a result of the partitioning between them. As the reinforcing means 130 is configured as a pair, the strength reinforcing effect may be increased compared to one reinforcing means 130 having the same volume. Of course, through this structure, there is also an advantage that the manufacture of the band-shaped reinforcing material 100 including the reinforcing means 130 becomes easy.

The resistance body 120 is provided with a resistance jaw 170. The resistance jaw 170 protrudes upward and downward of the strip base 102, respectively, and serves to increase the passive resistance friction force between the soil body and the strip-shaped reinforcement material 100. A plurality of resistance jaws 170 are provided along the base body 110 of the strip base 102 at predetermined intervals to increase passive resistance friction.

The resistance jaw 170 has a first resistance surface 171 and a second resistance surface 175. The first resistance surface 171 protrudes above the strip base 102 and is formed to face one side of the strip base 102 in the longitudinal direction. The second resistance surface 175 protrudes below the strip base 102 and is formed to face the other side of the strip base 102 in the longitudinal direction. That is, the first and second resistance surfaces 171 and 175 face opposite directions to each other.

In summary, the first resistance surface 171 and the second resistance surface 175 are formed to face opposite sides in the longitudinal direction of the strip base 102, and protrude opposite to each other in the upper and lower surfaces of the strip base 102. do.

Therefore, since the belt-shaped reinforcement 100 of the present invention has improved resistance in both the direction toward the retaining wall and in the opposite direction, the belt-shaped reinforcement 100 can be applied to more various environments and structures, and a specified installation due to the symmetrical structure Since there is no direction, it is possible to more conveniently construct the band-shaped reinforcement material 100.

Meanwhile, in this embodiment, the first resistance surface 171 and the second resistance surface 175 protrude in opposite directions and are connected to each other by a connection part 177 inclined with respect to the surface of the strip base 102. The structure of the first resistance surface 171, the second resistance surface 175, and the connection part 177 can form the first resistance surface 171, the second resistance surface 175, and the connection part 177 at the same time. To be there.

In the present invention, in the process of pulling the strip-shaped reinforcement material 100 in the direction toward the retaining wall, the backfilling soil B is caught on the first resistance surface 171 to generate resistance. Here, once the backfill soil B in contact with the first resistance surface 171 is in close contact with the backfill soil B at the rear thereof, a resistance force is generated. In this way, the backfilling soil (B) in contact with the first resistance surface 171 is no longer advanced and continues to be in close contact, so that the passive resistance can be further increased.

Meanwhile, a friction surface (A) is formed on an outer surface of at least one of the base body 110 and the resistance body 120. The friction surface (A) is formed in an uneven shape on the outer surface of the base body 110 or the resistance body 120, and is formed only on the base body 110 in this embodiment. In this embodiment, the friction surface (A) is formed in an approximately rhombus pattern to increase the passive resistance capability of the base body (110).

In this embodiment, the band-shaped reinforcement 100 is provided with two resistance bodies 120. The resistance body 120 is provided to be spaced apart from each other at a predetermined interval, and each of the resistance body 120 has a plurality of resistance jaws 170 formed at predetermined intervals in the longitudinal direction of the band-shaped reinforcing member 100. The resistance body 120 does not necessarily have to be provided with two in the band-shaped reinforcement 100, but may be provided with only one as shown in FIG.

Figure 4 shows a state in which the strip-shaped reinforcement 100 according to the present invention is installed on the back filling soil (B). As can be seen, the strip-shaped reinforcing material 100 may be installed in a number of different heights on the backfilling soil B, and may be constructed to reinforce a large area by being connected in a zigzag form in each layer (see FIG. 6). .

When the strip-shaped reinforcement material 100 is installed on the backfilling soil (B), even if an external force acts in the direction of the retaining wall, that is, in the direction of the installation block 200 (arrow ① direction), the passive resistance of the strip-shaped reinforcement material 100 is in the opposite direction (arrow ② As it acts as a direction), the passive resistance frictional force and pull-out resistance capability are guaranteed above a certain level, thereby improving the stability of the reinforced soil retaining wall.

Next, referring to the installation block 200 constituting the embodiment of the present invention, the installation block 200 is installed in front of the soil body, but a plurality of them are stacked with each other or installed in a parallel direction. In FIGS. 6 and 7, the installation blocks 200 are arranged in a horizontal direction, but the installation blocks 200 may be stacked on each other.

The installation block 200 has a block body 210 forming its skeleton. A portion of the upper surface of the block body 210 is concave at least as much as the thickness of the band-shaped reinforcement 100 to form a seating surface 212. As the seating surface 212 is concave, even if the belt-shaped reinforcement 100 is seated thereon, it is possible to prevent protruding as much as the thickness of the belt-shaped reinforcement 100. Accordingly, even if the installation blocks 200 are stacked, the phenomenon that the upper installation block 200 is inclined to the front can be prevented.

The block body 210 is formed with an insertion groove (H) in which a part of the band-shaped reinforcement 100 is inserted and seated. The insertion groove (H) of the installation block 200 can be largely divided into two types, a reinforcement insertion groove 215 and a post insertion groove 220. The reinforcing material insertion grooves 215 are configured as a pair so that a part of the band-shaped reinforcement material 100 can be extended in the opposite direction after being caught in an erect state. Here, the erected state means a state in which the band-shaped reinforcement 100 is bent in a vertical direction, and as shown in FIG. 7, a part of the band-shaped reinforcement 100 is bent and erected in the process of being combined with the installation block 200 As it enters the reinforcement insertion groove 215, it walks back in the opposite direction. For reference, in FIG. 7, the resistance jaw 170 is omitted from the band-shaped reinforcement 100.

On the other hand, the post insertion groove 220 is a portion in which a locking post is inserted through a portion of the belt-shaped stiffener 100 seated on the seating surface 212 while the belt-shaped stiffener 100 is laid down. Here, the lying state means that the band-shaped reinforcement member 100 extends in a horizontal direction, as shown in FIG. 6. The band-shaped reinforcement member 100 extends in the opposite direction after wrapping the locking post, and when the locking post is inserted into the post insertion groove 220 in this state, the band-shaped stiffener 100 may be fixed to the installation block 200. .

Both sides of the block body 210 are formed with coupling protrusions 230 and coupling grooves 235, respectively. The coupling protrusion 230 has a structure protruding from one side of the block body 210, and the coupling groove 235 is a concave portion in a shape corresponding thereto. The coupling protrusion 230 is inserted into the coupling groove 235 of another adjacent installation block 200, so that the position between the two adjacent installation blocks 200 can be accurately set, and the two installation blocks 200 It can also be rotated relative to each other.

According to the reinforcement assembly composed of the strip-shaped reinforcement material 100 and the installation block 200, the passive resistance friction force and the pull-out resistance capability are largely formed, and accordingly, the stability of the reinforced soil retaining wall can be improved. As shown in Figs. 1 and 4, when the backfill soil B on which the strip-shaped reinforcement material 100 is installed is pulled in the direction of the retaining wall (in the direction of arrow ①) and an external force acts, the strip base 102 of the strip-shaped reinforcement material 100 In addition, passive resistance frictional force is strongly generated by the resistance jaw 170, and a force that naturally supports it in the opposite direction (arrow ② direction) is provided.

In addition, even when constructing the strip-shaped reinforcing material 100, there is no need to consider the directionality. Since the first resistance surface 171 and the second resistance surface 175 are formed on the strip base 102 in opposite directions with respect to the two-direction axes, the strip-shaped reinforcement material 100 is both in the direction toward the retaining wall and in the opposite direction. Resistance is improved, and the band-shaped reinforcement material 100 can be applied to a wider variety of environments and structures. Regarding the construction, there is no specific installation direction due to the symmetrical structure of the strip-shaped reinforcement material 100, so that the strip-shaped reinforcement material 100 can be more conveniently constructed.

Meanwhile, the configuration of another embodiment of the present invention is shown in FIGS. 8 and 9. Here, the band-shaped reinforcing material 100 is simultaneously penetrated through the two blocks 300 on which the band-shaped reinforcement material 100 is stacked, but this is not necessarily the case, and only one block 300 may be penetrated. In the embodiment illustrated in FIG. 8, two stacked blocks 300 form one block layer, but one block 300 may form one block layer.

In addition, as shown in FIG. 8, one block of the upper layer on the two blocks 300 adjacent to the lower layer and the ones in the upper layer are arranged relatively to each other in the lower layer and the one in the upper layer. (300) is settled. As such, by stacking the blocks 300 alternately, there is an effect that the skin of the reinforcing earth retaining wall formed by the blocks 300 becomes solid.

The block body 301 forms the skeleton of the block 300. A front plate 303 forms a front portion of the block body 301. The front plate 303 forms the entire surface of the reinforcing earth retaining wall. A plurality of valleys are sequentially formed at both ends of the front plate 303 so as to be inclined to the rear. A rear plate 303 ′ forms a rear portion of the block body 301. The width of the rear plate 303 ′ is smaller than the width of the front plate 303. Both ends of the front plate 303 have irregularities (no drawing symbols) corresponding to each other, so that adjacent blocks 300 may be coupled to each other by fitting the irregularities.

A portion of the block body 301 connecting the front plate 303 and the rear plate 303 ′ has an approximately H-shaped cross section, but the block body 301 may have various shapes. . Through holes 305 are formed through the block body 301 vertically. The band-shaped reinforcing material 100 passes through the through hole 305.

There are two distal protrusions 307 on the upper surface of the block body 301. The tip protrusion 307 is formed to protrude from the rear adjacent to the front plate 303. Two rear protrusions 309 protrude from the upper surface of the block body 301 at a rear end, that is, a position adjacent to the rear plate 303'.

A front end channel 307' and a rear end channel 309' are formed on a lower surface of the block body 301 to correspond to the front end protrusion 307 and the rear end protrusion 309. In the leading channel 307' and the rear channel 309', a leading protrusion 307 and a rear protrusion 309 of a block that are relatively lower are located. The front end channel 307' and the rear end channel 309' are formed to cross the lower surface of the block body 303 horizontally.

Meanwhile, a reinforcing material passage 311 is formed in the rear plate 303 ′ of the upper surface of the block body 301. The reinforcement passage 311 is made by removing a part of the rear plate 303 ′, and allows the belt-shaped reinforcement 100 to pass between the block bodies 301 stacked up and down, so that the belt-shaped reinforcement 100 and the block Make sure that the body 301 does not interfere.

The specific configuration of the band-shaped reinforcement 100 is as described above. The strip-shaped reinforcement material 100 is extended in one direction to provide a frictional force between the rear filling soil 340 and the rear filling soil 340. In this embodiment, the band-shaped reinforcing material 100 is connected to the block 300 by penetrating the block 300 vertically, and the extension direction is changed based on the block 300. In addition, the portion of the band-shaped reinforcement material 100 protruding from the top and the portion of the strip-shaped reinforcement material 100 protruding from the bottom based on the through hole 305 of the block 300 are located in different layers within the backfill soil 340. do. Accordingly, the band-shaped reinforcement member 100 has an approximately intermediate portion thereof located in the through hole 305 of the block 300 and both ends thereof are at the rear end of the backfill soil 340. At this time, both sides of the strip-shaped reinforcing material 100 are positioned horizontally on different layers of the backfill soil 340 on both sides.

Further, although not shown in the drawings, as another embodiment, a panel may constitute the skin of the reinforced soil retaining wall in place of the block 300. At this time, the middle portion of the strip-shaped reinforcement material 100 may be connected to the panel by passing through the panel vertically, and both ends of the strip-shaped reinforcement material 100 may be entirely horizontally positioned on different layers of the backfilling soil 240.

In the above, even if all the constituent elements constituting the embodiment according to the present invention are described as being combined into one or operating in combination, the present invention is not necessarily limited to this embodiment. That is, within the scope of the object of the present invention, all of the constituent elements may be selectively combined and operated in one or more.
