Description

Assembled retaining wall structure

According to the present invention, a plurality of retaining wall blocks can be erected vertically in the vertical direction or constructed in a stepwise manner shifted from each other without a separate structural change or configuration addition. It relates to a prefabricated retaining wall structure capable of improving the structural stability of a retaining wall structure by adopting a structure in which a plurality of retaining wall blocks are integrally connected to each other in the vertical and left and right directions when constructing the retaining wall structure.

In general, a retaining wall refers to a wall made to prevent the collapse of a sloped topography formed by cutting the ground or stacking up the soil due to the pressure of the soil or the loss of the soil. For example, the retaining wall is built on a topography such as a fill site or a cut-off site to prevent the corresponding topography from collapsing due to soil pressure or soil loss.

Retaining walls were built using certain types of stone and cement in the past, but in this retaining wall construction method, cement had to be poured relatively thickly as the stones to be built are fixed only through the bonding force of cement, which reduces the time required for curing the cement. This resulted in a phenomenon in which the construction period of the retaining wall was excessively long. In addition, the retaining wall may be in danger of collapse if the water and moisture absorbed in the topography such as filled land and cut-off site are not properly discharged or if the volume expansion is made by freezing, cracks may occur. Therefore, recently, a method of constructing a retaining wall on a slope such as a fill site or a cut-off site by combining a plurality of blocks has been widely used.

The retaining wall construction method includes a construction method in which a plurality of blocks are stacked upright in a vertical direction, and a construction method in which a plurality of blocks are formed in a sloping stepwise manner on an inclined slope.

On the other hand, in the prior art, an example of constructing by interposing a support block between blocks stacked up and down for robustness after construction of the retaining wall block is applied. Although it can be easily applied to the second step stacking method, it has a structural problem that cannot be applied to the second step stacking method.

In addition, the currently applied retaining wall has weak bonding force between the upper and lower retaining wall blocks, so for example, when an external force is applied from the rear surface of the retaining wall toward the front, the retaining wall block moves due to the external force or, worse, between the upper and lower retaining wall blocks. There is a serious instability factor that can cause the entire retaining wall to collapse due to breakage.

In other words, in the prior art, a structure in which an anchor is provided on the upper part of the retaining wall block, another anchor is provided in the rear fill site (incision site), and a structure in which a wire is supported between the anchors is applied, but this support structure is also applied to the retaining wall block individually There is a problem in that the entire retaining wall structure collapses when any one of the retaining wall blocks supported by the bar deviate forward.

Accordingly, the present applicant has improved the retaining wall block structure so that a plurality of retaining wall blocks can be easily erected vertically in the vertical direction or constructed in a stepwise manner displaced from each other according to the work demand environment without a separate structural change or configuration addition, and the external force of the retaining wall When it is applied in the lateral direction of the block, it is proposed to propose a structure that can improve the structural stability of the retaining wall by maximally preventing separation between the upper and lower-stacked retaining wall blocks.

However, the present invention is not limited to the embodiments disclosed below, but will be implemented in a variety of different forms, only the present embodiments allow the disclosure of the present invention to be complete, and the scope of the design to those of ordinary skill in the art completely It is provided to inform you. In the drawings, like reference numerals refer to like elements.

The prefabricated retaining wall structure according to a preferred embodiment of the present invention improves the structure of the retaining wall block so that a plurality of retaining wall blocks can be erected vertically in the vertical direction or built in a stepwise manner displaced from each other without a separate structural change or configuration addition. Retaining wall construction design work can be easily changed according to the situation (constructing retaining walls by stacking upright in the vertical direction, constructing retaining walls in steps, etc.), thereby securing/providing flexibility of work. In addition, the prefabricated retaining wall structure according to the embodiment of the present invention employs a structure in which a plurality of upper and lower stacked retaining wall blocks are integrally connected to each other, and as any one retaining wall block collapses forward, the retaining wall stacked on the upper side Blocks will also collapse along with it, thereby preventing the entire retaining wall structure from collapsing.

Hereinafter, the present invention will be described with reference to various embodiments.

1 to 3 , the assembled retaining wall structure according to the first embodiment of the present invention includes a retaining wall block 100 and a support block 130 .

First, the retaining wall block 100 is made of a substantially rectangular parallelepiped shape, has a front surface 101 and a rear surface 102, and upper and lower surfaces are provided with upper and lower drainage grooves 103 and 107, respectively. Here, the upper and lower drain grooves 103 and 107 are formed to extend in the left and right directions to connect the left and right sides of the retaining wall block 100 to each other, respectively. In addition, an assembly protrusion 109 is provided on one side of the retaining wall block 100 and an assembly groove 110 is provided on the other side so that the assembly protrusion and the assembly groove can be coupled to each other adjacent to each other in the lateral direction.

Hereinafter, for convenience of explanation, the face facing the cut-off site (not shown) or the reclaimed land is referred to as the rear face, and the face facing the opposite direction is referred to as the front face, based on the state in which the retaining wall block 100 is constructed.

In an embodiment of the present invention, a lifting anchor (not shown) is provided in the upper drainage groove 103 for ease of lifting work using a crane or the like when constructing the retaining wall block. In addition, the rear foundation (not shown) is constructed in the rear filling land or cut-off site of the retaining wall block 100, and a support anchor (not shown) is installed on the rear foundation (not shown), and a lifting anchor (not shown) and a support anchor A support wire (not shown) may be installed to connect them (not shown), and for this, one end in the longitudinal direction is in communication with the upper drain groove 103 and the other end is in communication with the upper drain groove 103 on one side of the upper surface around the upper drain groove 103 for this purpose. A wire groove (not shown) that is opened to the outside is formed so that a support wire (not shown) can be disposed inside the wire groove (not shown). The present invention prevents the retaining wall block 100 from falling to the front side through the support force of the support wire (not shown), thereby constructing a solid retaining wall. The support base construction for supporting the lower part of the rear foundation and the plurality of retaining wall blocks 100 stacked in multiple stages can be applied to a conventional construction method and structure, and thus detailed descriptions thereof will be omitted.

Next, as shown in FIGS. 2 and 3 , the support block 130 is relatively lower with the lower drain groove 107 of the first retaining wall block located on the upper side when the retaining wall blocks 100 are stacked in the vertical direction. The upper and lower sides are respectively inserted into the upper drainage grooves 103 of the second retaining wall block located in

The support block 130 functions to more firmly maintain the stacked state between the upper and lower stacked retaining wall blocks 100 , and specifically supports the external force acting in the thickness direction of the retaining wall constructed through the retaining wall block 100 . Block 130 is disposed between the first retaining wall block and the second retaining wall block to prevent the corresponding retaining wall blocks from being pushed in the retaining wall thickness direction. That is, the support block 130 makes the stacking state between the retaining wall blocks more robust and at the same time allows the retaining wall to maintain a certain level of resistance to external force in the thickness direction, thereby greatly improving the structural stability of the retaining wall.

As described above, the present invention is made so that a plurality of retaining wall blocks can be erected vertically in the vertical direction or constructed in a stepwise manner displaced from each other without a separate structural change or configuration addition. In particular, by improving the structure of the retaining wall block 100, This can be implemented. Hereinafter, a structure for implementing this will be described in detail.

2 and 3 , at least two upper drainage grooves 103 are provided to be spaced apart from each other along the width direction (thickness direction) of the retaining wall block 100 to form a first drainage groove group 104 . and one lower drain groove 107 may be provided at the center of the retaining wall block 100 in the width direction.

Here, the support block 130 is selectively inserted among the first drain groove group 104 .

In order to implement both the vertical erection and stepped construction of the above-mentioned retaining wall, the upper drainage groove 103 may be applied as 1) a central drainage groove, the central drainage groove, and 2) a spaced drainage groove, a total of two, but in this case, the retaining wall There is no problem in the upright vertical lamination of blocks, but for stepwise lamination, the lower drainage groove 107 of the upper retaining wall block 100 and the 2) spaced drainage groove should always communicate with each other. Inconvenience arises in having to check on a daily basis.

In order to solve this inconvenience, in the present invention, for example, as shown in FIGS. 2 and 3 , the first drainage groove group 104 is a central drainage groove 105 provided at the center of the retaining wall block 100 in the width direction. ) and a pair of spaced apart drainage grooves 106 provided to be spaced apart from each other in both directions of the central drainage groove 105 may be included.

In this case, for the vertical upright stacking of the retaining wall block 100, the support block 130 is located on the upper side of the lower drainage groove 107 of the first retaining wall block located on the upper side and the upper drainage of the second retaining wall block located on the lower side. The upper and lower sides may be inserted into the groove 103, that is, the central drainage groove 105 of the first drainage groove group 104, respectively.

On the other hand, for the stepwise lamination of the retaining wall blocks 100, the lower drainage groove 104 of the first retaining wall block in which the support block 130 is located on the upper side and the upper drainage groove of the second retaining wall block located on the lower side relatively. (103), that is, the upper and lower both sides of the first drain groove group 104 are inserted into the spaced drain groove 106, respectively. In the present invention, as spaced drainage grooves 106 are provided on both sides based on the central drainage groove 105, respectively, it is easy to do without considering the front and rear arrangement directions of the second retaining wall block during the stepwise retaining wall construction work. Step stacking can be achieved.

Through this structure, the present invention can ensure/provide flexibility of work by making it possible to easily change the retaining wall construction design work according to the situation (constructing a retaining wall by stacking upright in a vertical direction, constructing a retaining wall in a stepped manner, etc.).

On the other hand, this retaining wall block structure has the advantage of being able to proceed by selecting vertical upright lamination and stepwise lamination as needed, but in particular, in the case of cascading lamination, the front surface of the first retaining wall block located at the upper side and the lower side relatively A phenomenon occurs in which the separation distance (the shortest distance between each front surface) between the front surfaces of the second retaining wall blocks located is inevitably fixed. That is, a phenomenon occurs in which the angle of inclination of the front face of the stepped retaining wall is fixed.

The present invention proposes an additional structure that can adjust the inclination angle of the front slope of the stepped retaining wall as needed.

To this end, as shown in FIG. 3 , in the first embodiment of the present invention, at least two lower drain grooves 107 are provided to be spaced apart from each other along the width direction of the retaining wall block 100 and the second drain groove group (108). Here, the second drainage groove group 108 may include a central drainage groove and a spaced drainage groove in the same/similar manner to the first drainage groove group 104 , and the support block 130 includes the second drainage groove group 108 . ) is selected and inserted.

For example, the spaced drainage groove 106 of the first drainage groove group 104 of the second drainage groove group 108 of the relatively upper first retaining wall block and the spaced drainage groove 106 of the second drainage groove group 108 of the relatively lower second retaining wall block. and the support block 130 may be inserted into the communicating portion. In addition, the central drainage groove of the second drainage groove group 108 of the first retaining wall block on the upper side and the spaced drainage groove 106 of the first drainage groove group 104 of the second retaining wall block on the lower side communicate with each other. And the support block 130 can be inserted into the communicating portion. In addition, the position at which the support block 130 is inserted can be changed by adjusting the arrangement position between the first retaining wall block and the second retaining wall block, and accordingly, the inclination angle of the front inclined surface of the stepped retaining wall can be variously adjusted as described above.

On the other hand, the retaining wall construction work is performed by repeating the operation of lifting the retaining wall blocks one by one through a crane and placing them on the upper side of the previously loaded retaining wall blocks, but there is a problem in that it is difficult for the operator to check the lower surface of the retaining wall blocks. That is, it is difficult to accurately determine the position of the second drainage groove group 108 formed on the lower surface of the retaining wall block 100. In order to solve the problem of difficult to seat the retaining wall block at an appropriate position, as shown in FIG. An identification groove 111 is provided on the side of the retaining wall block 100 at a position corresponding to the position where the second drainage groove group 108 is formed.

Therefore, the operator can check the position of the second drainage groove group 108 through the identification groove 111 position, and accordingly, the seating position of the first retaining wall block with respect to the second retaining wall block can be easily adjusted as described above. In the end, it is possible to easily carry out the work of adjusting the inclination angle of the stepped retaining wall.

Hereinafter, the assembly-type retaining wall structure according to the second embodiment of the present invention will be described, and repeated descriptions of the same components as those of the first embodiment will be omitted, and reference numerals starting with number 200 will be used for the same components.

The second embodiment of the present invention is generally the same/similar to the first embodiment, except that the formation position of the drain groove group is different from that of the first embodiment.

In the second embodiment of the present invention, as shown in FIG. 5 , one upper drainage groove 203 is provided at the center of the width direction (thickness direction) of the retaining wall block 200, and the lower drainage groove 207 is At least two or more may be provided to be spaced apart from each other along the width direction of the retaining wall block to form the first drainage groove group 221 .

Here, the lower portion of the support block 230 is inserted into the upper drain groove 203 , and the upper portion of the support block is inserted into the lower drain groove 207 , that is, the first drain groove group 221 .

Here, as shown in FIG. 5 , the first drainage groove group 221 is spaced apart from each other in both directions of the central drainage groove 222 and the central drainage groove 222 provided at the center of the retaining wall block 200 in the width direction. It may include a pair of spaced apart drain grooves 223 provided to be.

In this case, since the arrangement (insertion) position adjustment of the support block 230 for the vertical upright stacking and the stepwise stacking of the retaining wall block 200 is the same/similar to the first embodiment, the overlapping description will be omitted below.

On the other hand, this retaining wall block structure has the advantage of being able to proceed by selecting vertical upright lamination and stepwise lamination as needed, but in particular, in the case of cascading lamination, the front surface of the first retaining wall block located at the upper side and the lower side relatively A phenomenon occurs in which the separation distance (the shortest distance between each front surface) between the front surfaces of the second retaining wall blocks located is inevitably fixed. That is, a phenomenon occurs in which the angle of inclination of the front face of the stepped retaining wall is fixed.

The present invention proposes an additional structure that can adjust the inclination angle of the front slope of the stepped retaining wall as needed.

To this end, although not specifically shown in the drawings, in the second embodiment of the present invention, at least two upper drainage grooves 203 are provided to be spaced apart from each other along the width direction of the retaining wall block, and upper drainage grooves 203 are provided. may include 1) a central drain groove and 2) a spaced drain groove, as described above, and the support block 230 is inserted into one of 1) a central drain groove and 2) a spaced drain groove.

The method for adjusting the inclination angle of the front surface of the retaining wall stacked in steps through this structure will be omitted below as described in the first embodiment.

On the other hand, the retaining wall construction work is performed by repeating the operation of lifting the retaining wall blocks one by one through a crane and placing them on the upper side of the previously loaded retaining wall blocks, but there is a problem in that it is difficult for the operator to check the lower surface of the retaining wall blocks. That is, it is difficult to accurately determine the position of the first drainage groove group 221 formed on the lower surface of the retaining wall block 200. In order to solve the problem of difficulty in seating the retaining wall block in an appropriate position, the side surface of the retaining wall block 200 An identification groove is provided at a position corresponding to the position where the first drain groove group 221 is formed. The identification groove has the same shape/structure as that of the identification groove described in the first embodiment, and a detailed illustration through the drawings will be omitted.

Therefore, the operator can confirm the position of the first drainage groove group 221 through the identification groove position, and accordingly, as described above, the seating position of the first retaining wall block with respect to the second retaining wall block can be easily adjusted, and eventually, a stepwise process The inclination angle adjustment of the retaining wall can be easily carried out.

Hereinafter, an assembled retaining wall structure according to a third embodiment of the present invention will be described, and various configurations described in the third embodiment are applicable to both the first embodiment and the second embodiment, and for convenience of explanation and illustration For this purpose, the first embodiment is applied as a reference, and reference numerals starting with the number 300 are used for the same configuration.

Hereinafter, an additional structure capable of maintaining the construction state of the structure more stably in addition to the solid construction structure of the retaining wall structure by the above-described lifting anchor, support anchor, and support wire described in the first embodiment will be described.

An anchor 340 may be provided, and two anchors 340 may be provided as shown in FIG. 7 , and for convenience of description, the former case is illustrated and described below.

In addition, a more detailed description of the anchor and related drawings will be described based on a state in which the stepped stacking structure is applied as the first and second embodiments have described the stepped stacking structure.

The anchor 340 has a vertical connection hole 341 through which the vertical connection support wire 360 can be inserted so as to integrally connect the plurality of retaining wall blocks 300 stacked in the vertical direction using the vertical connection support wire 360 . will be prepared

Therefore, the plurality of retaining wall blocks 300 stacked in a stepwise manner can be integrally connected to each other through the vertical connection support wire 360, and for example, even when a certain or more external force is intensively applied to the rear surface of any one retaining wall block. It is possible to prevent the entire retaining wall structure from collapsing or collapsing forward, including the retaining wall block to which an external force is applied, through a structure that is integrally connected to each other in the vertical direction.

Hereinafter, an assembled retaining wall structure according to a fourth embodiment of the present invention will be described, and various configurations described in the fourth embodiment are applicable to both the first embodiment, the second embodiment, and the third embodiment. And for convenience of illustration, the first embodiment is applied as a reference, and reference numerals starting with 400 are used for the same configuration.

9 to 11 , in the fourth embodiment of the present invention, the anchor 440 connects a plurality of retaining wall blocks 400 adjacent to each other in the left and right direction using a left and right connection support wire 480 . The left and right connection holes 471 through which the left and right connection support wires 480 can be inserted are further provided to be integrally connected. The vertical connection support wire 460 and the left and right connection support wire 480 are applicable as reinforcing bars and the like.

Specifically, in the anchor 440, in addition to the anchor connecting rod and the upper and lower connecting portions in the third embodiment, branch connecting rods 472 and left and right connecting holes 471 that branch in the upper or lower direction of the anchor connecting rod 442 are formed and branched. It further includes a left and right connection portion 473 provided at the end of the connecting rod (472).

Therefore, a plurality of retaining wall blocks 400 disposed adjacent to each other in the left and right direction can be integrally connected to each other through the left and right connection support wires 480, for example, a certain amount of external force is concentrated on the rear surface of any one retaining wall block. Even when applied to each other, the entire retaining wall structure, including the retaining wall block to which external force is applied, can be prevented from collapsing or collapsing forward through the structure integrally connected to each other in the left and right directions.

In addition, the plurality of vertically stacked retaining wall blocks 400 are integrally connected through the upper and lower connection holes 441 and the upper and lower connection support wires 460 , and the plurality of retaining wall blocks 400 disposed adjacent to the left and right are connected to the left and right. By integrally connecting through the hole 471 and the left and right connection support wires 480 as well, substantially all the retaining wall blocks 400 of the retaining wall structure are not individually supported, but integrated support connected in both the up and down and left and right directions is possible. It is possible to provide the construction state of a solid retaining wall structure.

On the other hand, if the upper and lower connection part 443 is a structure fixed to the end of the anchor connection rod 442, the vertical connection support wire 460 must be inserted only in the vertical connection part 443, and the left and right connection support wire 480 must be the left and right connection part A situation arises where only (473) should be inserted. However, depending on the work site, there may be situations in which it is necessary to change the arrangement position of the vertical connection support wire and the left and right connection support wire. In some cases, it may be difficult to construct a retaining wall smoothly.

The present invention is to solve this problem, as shown in FIGS. 10 and 11, the upper and lower connection parts 443 are rotatably coupled to the anchor connection rods 442 so as to be separable, and the branch connection rods 472 are retaining wall blocks 400. It is obliquely connected to the anchor connecting rod 442 so as to be inclined with respect to an imaginary plane including the bottom surface of the .

Specifically, the upper and lower connection parts 443 can be coupled to the anchor connection rod 442 through screw coupling, etc., and the branch connection rod 472 is inclined and integrally formed with the anchor connection rod 442 to have an inclination angle of 40 to 60 degrees, for example. do. Accordingly, as shown in FIG. 10 by adjusting the screw fastening depth, the user freely converts the arrangement direction of the upper and lower connection parts 443 with respect to the rear surface of the retaining wall block 400 to the upper and lower connection parts 443 as needed. A vertical connection support wire 460 or a left and right connection support wire 480 may be inserted.

For reference, the length (in the left and right direction) of the vertical connection support wire insertion groove 461 formed on the lower surface of the retaining wall block 400 is the vertical connection support wire 460 is inserted into the vertical connection part 443 or the left and right connection parts 473 ), even when the vertical connection support wire 460 is inserted, the upper end of the vertical connection support wire 460 is formed to a length that can be inserted.

In addition, since the branch connecting rod 472 is obliquely connected to the anchor connecting rod 442, the left and right connection support wires 480 are connected to the vertical connection part 443, and the vertical connection support wires 460 are connected to the left and right connection parts 473. In this case, it is possible to solve a situation in which the vertical connection support wire 460 interferes with the anchor connection rod 442 and is not properly installed.

That is, the present invention 1) screws the upper and lower connection parts 443 to the anchor connection rod 442 to freely adjust the arrangement position of the vertical connection hole 441, 2) the branch connection rod 472 to the anchor connection rod 442. By connecting at an angle, inserting the vertical connection support wire 460 into the vertical connection hole 441 and inserting the left and right connection support wire 480 into the left and right connection hole 471, easily change the installation position of the support wires and apply can do.

Although the present invention has been described with reference to the accompanying drawings and the above-described preferred embodiments, the present invention is not limited thereto, and is defined by the utility model registration claims to be described later. Therefore, those of ordinary skill in the art can variously modify and modify the present invention within the scope without departing from the technical spirit of the utility model registration claims to be described later.
