Description

Three-dimensional retaining wall block system

The present invention relates to a three-dimensional retaining wall block system, and more specifically, in the retaining wall block, a column connection block that acts as an upper and lower column is introduced between the front connection blocks with a coupling groove, and a side connection that allows the construction of various retaining walls such as curved ones. This relates to a three-dimensional retaining wall system that can not only strengthen the bonding power of the blocks themselves by introducing blocks, but also build a retaining wall with an attractive exterior structure.

In general, a retaining wall refers to a wall structure to prevent ground collapse, and is divided into so-called flattening, which involves excavating the ground higher than the surrounding area, and embankment, which increases the height of the ground by piling soil on the ground.

In the case of steep slopes formed by cutting and filling, they are easily destroyed by rainfall or earthquakes, and the steep slopes become prone to collapse and fall. Therefore, a retaining wall, a wall-shaped architectural structure, is installed on such a slope, that is, a slope, to prevent collapse.

Most of the uses of retaining walls or embankments are applied to cut surfaces formed by cutting existing slopes and fill surfaces formed by filling new soil. In the case of the cut surface, the original ground is exposed, so it generally forms a more stable structure compared to the fill surface. In most cases, it is a rock surface such as hard rock, soft rock, or weathered rock, or a soil surface that has been compacted over a long period of time, and a retaining wall or embankment structure is installed close to the cut surface. A method of fixing the structure using the gravity of the structure itself or a nailing method on the cut surface is mainly used.

On the other hand, in the case of a fill slope formed by piling up new soil, it is said that safety is secured by compacting the soil, but compared to the original ground, safety may be very low, so construction methods such as reinforced concrete retaining walls or reinforced soil retaining walls are mainly used. Reinforcement work must be done with a width of 60 to 80% or more of the slope height. At this time, reinforcing materials called grids and reinforced soil retaining walls are mainly used.

However, in actual construction sites, the characteristics of the target ground are often not constant, and include many curved sections, and there are cases where cut and fill slopes are adjacent to each other, and the workpiece is located in the middle of the construction section. Therefore, there are often cases where several methods have to be used in combination.

Prior art proposed to improve this problem includes Korean Patent Publication No. 10-2019-0057208, “Prefabricated Earthquake-Resistant Retaining Wall Block System,” which relates to a method of constructing retaining wall blocks assembled with an improved interlocking method to increase the cohesion between blocks. However, it is a retaining wall construction method that repeatedly stacks simple combined basic blocks. Recently, due to global environmental changes and frequent earthquakes, retaining walls have collapsed, causing many casualties and property damage. Therefore, it is necessary to create a more robust bond and earthquake-resistant design of various buildings. The importance of is emphasized.

Meanwhile, with the recent increase in the development of country houses and mountainous areas seeking healing with nature, self-construction products such as embankments using small combination blocks are increasing, and a DIY retaining wall construction system that meets this demand is in demand.

The present inventors have been constructing retaining wall blocks for many years, and by introducing upper and lower column connection blocks that serve as upper and lower columns to retaining wall blocks with joint grooves, not only can a gravity-type retaining wall structure be formed through three-dimensional bonding of the blocks themselves, but also a grid is formed on the embankment slope. Construction can be done by applying, and in the case of cut slopes, especially when the back length is not sufficient, the nailing method can be used. By creating a space for vegetation, it is possible to create an eco-friendly landscape, and a wide variety of cross sections can be created depending on the conditions of the site. Since it can be constructed, the present invention was completed by successfully developing a method of creating a stable and optimal retaining wall or embankment of an original shape.

The present invention is intended to solve the above problems, and provides a three-dimensional retaining wall system that strengthens the bonding force of the blocks themselves by introducing upper and lower column connection blocks that serve as upper and lower columns in the retaining wall block.

Another object of the present invention is to introduce a column connection block that acts as an upper and lower column between the front connection blocks with a connection groove in the retaining wall block, and also to introduce a side connection block capable of constructing a curved retaining wall to improve the connection strength of the blocks themselves. The goal is to provide a three-dimensional retaining wall system that can build a retaining wall with a strengthened and beautiful structure.

Another object of the present invention is that not only can a gravity retaining wall structure be formed through three-dimensional bonding of the blocks themselves, but it can also be constructed by applying an existing grid on the embankment slope, and can be constructed by connecting blocks manufactured by recycling plastic. A three-dimensional grid can be formed to replace the existing grid. In the case of cut slopes, especially when the back length is not sufficient, the nailing method can be used, and by creating a space for vegetation, it is possible to create an eco-friendly landscape and create an environmentally friendly landscape. The purpose is to provide a three-dimensional block system to enable the creation of a unique, stable, and optimal retaining wall or embankment since it can be configured with a wide variety of cross-sections depending on the conditions.

As an example, the curved side joining block 300c is characterized in that one side and the other side are formed with different lengths, so that a curved surface can be formed when continuously joined to the side.

In addition, it is characterized by installing a reinforcing bar coupling unit that connects a number of blocks to fit the horizontal reinforcement groove 110 formed in the front connecting block 100, which is connected to the side part of the column connecting block 200, which acts as a pillar by connecting the top and bottom.

It is characterized by being able to replace .

In addition, in order to securely hold the back of the front connection block 100, four connections formed on one basic side connection block 300a are formed correspondingly to each rear connection portion 140 of the front connection block 100. .

In addition, the basic side connection block 300a is a basic side connection block made of porous concrete, which is formed to play the role of a drainage layer, or is replaced with a basic side connection block using waste plastic to form a three-dimensional grid.

At this time, the reinforcing bar may be inserted into the horizontal reinforcement groove 110.

In addition, it may be characterized in that the gravity retaining wall structure is formed through three-dimensional bonding of the blocks themselves, including the front connection block 100.

In addition, the block including the front connection block 100 may be constructed by applying a grid on the embankment slope, and in the case of the cut slope, a nailing method may be used, especially when the back length is insufficient.

In addition, it is possible to create an eco-friendly landscape by creating a vegetation space when the planting area is exposed, and by configuring multiple cross-sections according to the fastening structure between the front connection blocks (100) depending on the conditions of the site, a stable optimal and unique shape can be achieved.

Referring to the drawing, the three-dimensional block system (1) according to an embodiment of the present invention can not only form a gravity retaining wall structure through three-dimensional bonding of the blocks themselves, but also can form a grid on the embankment slope as shown in FIG. Construction can be done, and in the case of cut slopes, especially when the back length is not sufficient, the nailing method can be used. By creating a vegetation space as shown in Figure 6, it is possible to create an eco-friendly landscape, and a wide variety of cross sections can be created depending on site conditions. We provide a retaining wall block and its system that enable the creation of a unique, stable, and optimal retaining wall or embankment.

All basic blocks used in the present invention have connection parts (side connection parts, rear connection parts) connected to each other to the same standard, so that structural combination is possible, and include a front connection block 100 that forms the front of the retaining wall; Column connection blocks 200 that are coupled between the front connection blocks and serve as upper and lower columns; A side coupling block (300) connected to the front connection block is assembled and connected to each other.

The three-dimensional retaining wall system of the present invention can secure planting space by constructing a front connection block and a column connection block on the upper part of the foundation block to secure planting space in a stepped construction, and can secure planting space depending on how many stages the front connection blocks are stacked and moved back. The slope of the slope can be adjusted, and if necessary, rebar can be placed in the pillar connection block and ready-mixed concrete can be poured, and safety can be further improved by driving a steel beam or pillar into the ground.

At this time, the pillar connection block 200 is installed with one or two hollow parts in the middle, and when interconnected, reinforcing bars are inserted vertically and ready-mixed concrete is poured to play the role of a reinforced concrete pillar, thereby ensuring greater safety.

For example, construction can be simplified by replacing the foundation of a retaining wall, and connectivity with the blocks on the upper part of the foundation can be secured. Instead of installing formwork and constructing a foundation, you can construct blocks as shown in the picture above, place reinforcing bars through horizontal and vertical reinforcement holes, and then use ready-mix concrete to replace the concrete foundation. Installing the form and disposing the rebar using the existing method is complicated and expensive, but since the form can be replaced by leveling the floor and immediately installing blocks, the process can be simplified while saving time and cost. In addition, since connectivity with the side connection block can be secured, it can be integrated with the block constructed at the top, which has the advantage of securing greater safety.

In addition, the column connection block 200 and the front connection block 100 each have a half-length block of 1/2 height installed at the first stage to create a step difference between the front connection block 100 and the column connection block 200, respectively. It can be characterized as being tightly connected by interlocking with each other.

In addition, by connecting the pillar connection block 200, which acts as a pillar by vertical connection, and the above-described side coupling block 300, which is connected to the side part of the front connection block 100, the lengths of one side and the other side are different. By forming it, a curved surface can be formed, making it possible to build a beautiful retaining wall to suit the terrain or surrounding environment. Here, the side coupling block 300 includes a basic side coupling block 300a that is simply connected as shown in Figure 3, a finished side coupling block 300b formed for finishing, and a curved side using the difference in curvature of the connection sides. Combination block 300c may be used.

The side coupling block 300 has a half-length block, so it can secure three-dimensional connectivity by connecting the front connection blocks, and plays a role when it is necessary to secure a wider cross-section at the back. The curved side joining block (300c) is used when one side and the other side have different lengths to form a certain curved surface, and the angle is 9 degrees to 45 degrees per curved block. Allows you to form angles within the range of degrees.

In addition, the front connection block 100, which is connected to the protruding side connection part 210 corresponding to the side part of the pillar connection block 200, which acts as a pillar by vertical connection, and its side connection part 130, is horizontal on the upper surface. Horizontal reinforcement grooves 110 formed on both sides of the direction, and two rear connection reinforcement grooves 120 formed on the upper surface of the rear area while spaced apart from each other in a direction perpendicular to the horizontal reinforcement groove 110 are formed. there is.

On the other hand, the front connection block 100 is formed with a side connection part 130 consisting of a protruding end and a concave end for connection on the left and right sides, and the side connection parts 130 on both sides have the protruding end and the concave end of the objects on both sides based on the horizontal direction. The stages may be formed in directions that intersect diagonally. And, in the front connection block 100, a rear connection part 140 is formed in the rear area corresponding to the opposite side of the front, and a total of four rear connection parts 140 are formed with a concave end and a protruding end as a pair, and two One rear connection part 140 may be formed on both sides around the rear connection reinforcement groove 120, and two rear connection parts 140 may be formed between the two rear connection reinforcement grooves 120, and a concave end and a protrusion may be formed on the rear side. It may be formed in a shape where the stages are formed alternately. This rear connection portion 140 forms a shape that allows the front connection block 100 at the front and rear ends to be firmly fastened as shown in FIG. 5, and is horizontal to the rear connection reinforcement groove 120 of the front connection block 100 formed at the front and back. The reinforcement groove 110 forms a square-shaped groove, which can provide the effect of enabling more solid fastening through reinforcement in the formed groove.

In addition, safety can be further ensured by inserting reinforcing bars horizontally and pouring ready-mix concrete into these square-shaped grooves to serve as a reinforced concrete foundation, when necessary.

In addition, the pillar connection block 200, which acts as a pillar by connecting up and down, can play the role of a reinforced concrete pillar by inserting and arranging reinforcing bars into two vertical groove spaces when stacked at a certain height and pouring ready-mixed concrete, creating a safer structure. can be provided.

During the nailing method using the rear connection reinforcement groove 120 as shown in Figure 8, the reinforcing bars on the wall do not deviate from the horizontal reinforcement groove 110, so that nailing is possible while stacking them in a row on the side, thereby providing the effect of fixing them to the wall. can be provided.

Meanwhile, on the body of the front connection block 100, on the second side body formed on the opposite side of the first body based on the horizontal reinforcement groove 110, a rear connection reinforcement groove ( 120) is formed, and the horizontal reinforcement groove 110 is formed into three divided areas in the longitudinal direction as shown in Figure 1, and the two horizontal reinforcement grooves 110 formed on both sides of the central horizontal reinforcement groove 110 Two grooves may be formed on the second side body in a direction perpendicular to the area ending inward.

The pillar connection block 200 has a half-length block as shown in Figure 2 (see Figure 5), so that it is possible to secure their three-dimensional connectivity by connecting the front connection blocks 100, and there is a need to secure a wider cross-section at the back. It plays a role when present, and the curved side bonding block (300c), which is a curved block among the three-dimensional bonding blocks (300), is used when one side and the other side have different lengths to form a certain curved surface, and the angle is the side bonding block (300c). Each connection block 300 can form an angle in the range of 9 degrees to 45 degrees.

In addition, referring to Figures 8 and 9, a composite (cut-out soil) retaining wall can be installed by installing horizontal reinforcement and rear connection reinforcement and connecting them by nailing.

More specifically, referring to the horizontal reinforcement and connection reinforcement installation drawings (nailing connection drawings) at the rear, as shown in FIGS. 8 and 9, in the case of cut slopes, it is difficult to secure a sufficient area on the rear of the retaining wall, so it is difficult to secure a sufficient area on the rear wall. Safety was ensured by installing the retaining wall as close as possible and fixing the back and retaining wall using the nailing method. Since the entire block is connected as one structure, it is a method that is simpler to construct and is advantageous in ensuring safety compared to the existing nailing method.

Meanwhile, in the case of an embankment slope as shown in Figure 7, the front connection blocks are connected at the same height and the grid is installed on the surface formed at the same height, so that not only can grid installation be facilitated, but also the front connection blocks are all horizontal. Safety is improved compared to existing reinforced earth blocks that are connected and installed as individual units, and since each stage of the front connection block is three-dimensionally connected to the column connection block, all blocks ultimately form an integrated structure, further securing safety. You can.

In particular, in cases where fill slopes and cut slopes occur complexly, and structures such as electrical wiring outlets must be located in the middle, this method involves constructing blocks around the boundary, avoiding the structures, which was impossible with any existing retaining wall. It is a useful method that can realize a composite cross-section retaining wall method.

Referring to FIG. 10, in order to securely hold the front connection block 100 behind, the four connection parts formed on one basic side coupling block 300a per rear connection part 140 of the front connection block 100 are formed to correspond. , The basic side-joining block 300a can be formed as a basic block made of porous concrete, or by forming a block using waste plastic, so that it can serve as a drainage layer. Here, not only is a reinforcement groove formed on the upper surface of each connection part of the basic side coupling block 300a, but it is also formed in a shape connected to the rear connection reinforcement groove 120 of the front connection block 100, and is strongly held by the reinforcement reinforcement. I can give it.

In addition, it is possible to construct a retaining wall structure with an integrated drainage layer using basic side joining blocks made of porous material, and by using basic side joining blocks using waste plastic to form a three-dimensional grid instead of the existing grid. It was possible to construct retaining walls and embankments that further strengthened safety.

At this time, the basic side coupling block that is firmly held behind the front connection block (100) can be made of a porous material, or a three-dimensional block system with an integrated drainage layer can be constructed with an empty space in the middle.

In particular, side-joining blocks made of waste plastic materials exhibit a tensile strength more than 100 times that of plain concrete blocks of the same standard, so they have the characteristic of being able to produce greater effects than existing grids even with a small cross-section.

At this time, the basic side connection block that is firmly held behind the front connection block 100 may be manufactured using waste plastic and formed into a T-shaped structure to serve as a more sturdy grid.

As described above, the specification and drawings disclose preferred embodiments of the present invention, and although specific terms are used, they are used only in a general sense to easily explain the technical content of the present invention and aid understanding of the invention. , it is not intended to limit the scope of the present invention. It is obvious to those skilled in the art that in addition to the embodiments disclosed herein, other modifications based on the technical idea of the present invention can be implemented.
