Description

Construction method of reinforced green retaining wall

The present invention relates to a retaining wall that is constructed on a cutting or stacking slope or a lakeside slope, and relates to a preferable method for constructing a retaining wall constructed of vegetation space between a reinforced concrete column and a reinforced concrete column.

A slope protection work is carried out to prevent the collapse of slopes such as banks, banks, cuts, and piles. There are various methods of slope protection, depending on the slope of the slope.

For steep slopes, the slopes are stabilized with slope slope reinforcements such as nail nails, earth anchors, and rock bolts, and then protected with a grid block or seed spraying. Lattice block protection method has the advantage of excellent slope protection effect, but because the block is large construction is difficult to install on the steep slope, there is a problem that is mostly lost when planting in the space in the block after cover. The seed spraying method has the advantage of recording the whole surface by mixing organic soil, stabilizer, and seed on the slope, but it is not only easy to be lost during heavy rain, but also has severe cracking and water. There are disadvantages.

Stacking slopes with a slight slope are usually constructed with block stacking, stone stacking or reinforcement soil walls, but these methods are expensive and difficult to green.

Reservoir slopes with sloping slopes, ridges, and curved slopes should be constructed with vegetation blocks or gabion retaining walls. The vegetation block construction method has a disadvantage in that the construction cost is high, such as the use of expensive materials and expensive equipment, because heavy weight should be used in order to prevent the departure and step difference during flooding. The gabion retaining wall construction method has a disadvantage in that the connection structure between the filling stones is vulnerable, and local filling phenomenon is likely to occur.

The present invention has been developed in order to improve the problems of the above-described conventional slope protection work has the following technical problems.

First, the present invention is to provide a method for structurally stable slope protection work while implementing the entire or part of the front surface as vegetation space.

Second, to provide a slope protection construction method that can be applied to a variety of slopes, such as shaved or stacked slopes, as well as shore slopes.

Third, to provide a slope protection method that can flexibly respond to the bent section of the slope.

Fourth, to provide a slope protection work method that can easily proceed with the formwork and concrete construction.

In order to solve the above technical problem, the present invention, while installing the pillar formwork on the stabilized slope front and reinforces the column reinforcement and placing the pillar concrete through the process of spacing the reinforced concrete pillar along the slope surface, the pillar form the front A first step of installing the anchor to protrude through and constructing the anchor to protrude and fix the front of the reinforced concrete pillar; A second step of fixing the vegetation mat disposed on the front of the reinforced concrete column and securing the vegetation mat covering the vegetation mat and fixing the vegetation soil between the inclined surface and the vegetation mat; And, a third step of repeating the second step at the height of the retaining wall; provides a reinforced green retaining wall construction method comprising a.

According to the present invention, the following effects can be expected.

First, since reinforced concrete pillars are installed on slopes and vegetation spaces are constructed between reinforced concrete pillars, eco-friendly and structurally stable retaining walls can be constructed.

Second, since it is applied to slopes stabilized by magnetic force or stabilized with various slope reinforcement holes (soil nails, earth anchors, rock bolts, etc.), the greening retaining wall can be advantageously applied to not only cutting or stacking slopes but also lake slopes. Can be. In particular, when slope slope reinforcement is applied to the slopes on which the slope slope reinforcement is applied, the head of the slope slope reinforcement is buried in the reinforced concrete column, which is part of the retaining wall sphere, thereby enhancing slope integrity while strengthening the integrity of the slope slope reinforcing hole and the retaining wall sphere.

Third, because the reinforced concrete pillars are sparsely constructed, the curved section of the slope can be configured as a vegetation space without constructing the reinforced concrete pillars. Accordingly, the vegetation space can be realized as a vegetation mat, a protective wire mesh, or a vegetation soil that can be relatively freely changed. Thus, the green retaining wall can be constructed while flexibly responding to the curved section of the slope. Furthermore, maintenance of sparsely constructed reinforced concrete columns is simple.

Fourth, because the prefabricated pillar formwork is proposed to construct reinforced concrete pillars on the slope, it is possible to construct greening retaining walls while simplifying the reinforced concrete construction.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

1 illustrates various embodiments of a reinforced green retaining wall according to the present invention. Reinforced greening retaining wall according to the present invention constructs the reinforced concrete column (10) in the construction of the retaining wall on the cutting or stacking slope (S) or rake slope (S) and constitutes the vegetation space between the reinforced concrete pillars (10) There are technical features. In order to implement such technical features, the present invention includes a reinforced concrete column 10, an anchor 20, a vegetation mat 31, a protective wire mesh 32, and a vegetation soil 41 as essential components, and a reinforcing grid. (42), the gabion 33, and the filling stone 43 is included in an optional configuration.

Reinforced concrete column 10 is constructed along the stabilized slope (S) while being spaced along the slope (S) from side to side. Slope stabilized in the present invention (S) means the ground stabilized by having an inclination of less than the angle of repose or reinforced with a slope reinforcing hole (S4), such as a small nail, earth anchor, rock bolt, stabilized slope in the present invention (S) may be a direct ground surface (S1), as well as a non-woven fabric (S2), drain plate (S3), etc. are treated on the ground surface (S1), in particular slope slope reinforcement hole by a small nail ( When it is reinforced with S4), it will be in the state surface-treated with shotcrete S41.

In Figure 1 (a) it can be seen that the reinforced concrete pillar 10 was constructed on the slope surface (S) surface-treated with the shot concrete (S41), in Figure 1 (b) the reinforced concrete pillar (10) is a nonwoven fabric (S2) And it can be confirmed that the drainage plate (S3) has been constructed on the treated slope surface (S), in Figure 1 (c) can be confirmed that the reinforced concrete column 10 was constructed on the slope surface (S) of the state that is not treated anything. have. Furthermore, in Figure 1 (a) (b) (c) it can be confirmed that the reinforced concrete column 10 was constructed on the slope surface (S) reinforced by the slope surface reinforcing hole (S4), in this case the reinforced concrete column (10) The projecting head of the slope reinforcing hole (S4) is built in the interior. As the projecting head of the slope-surface reinforcing hole (S4) is embedded in the reinforced concrete column 10, the reinforced concrete column 10 is expected to serve as a pressure plate. That is, because the projecting head of the slope reinforcing hole (S4) and the reinforced concrete pillar (10) is integrated, when the tensile force acts on the slope reinforcing hole (S4) in the ground, the tensile force is transmitted to the reinforced concrete pillar (10) and slopes (S). It is converted to the pressure by pressing).

Reinforced concrete column 10 is preferably a trapezoidal cross-sectional shape that becomes narrower toward the front as shown in Figure 1, to minimize the front exposure of the reinforced concrete column 10 to maximize the greening area of the retaining wall front . Furthermore, the reinforced concrete column 10 may be constructed such that continuous grooves 13 are formed in the front in the longitudinal direction as shown in FIG. 1 (c), which is to minimize the external protrusion of the anchor 20. .

Anchor 20 is configured to be fixed to protrude in front of the reinforced concrete pillar (10). Anchor 20 can be installed by drilling the perforated reinforced concrete pillar (10) completed, and can also be installed while fixing to the pillar concrete 12 during the reinforced concrete pillar (10) construction process. Particularly, in the case of purchasing the anchor 20 to the pillar concrete 12 during the construction of the reinforced concrete column 10, the anchor 20 may include a reinforcement spacer RS for reinforcing the column reinforcement 11 of the reinforced concrete column. It may be provided in an integrated form (see FIG. 4). If the continuous groove 13 is formed on the front of the reinforced concrete pillar 10, as shown in Figure 1 (c) anchor 20 is located in the continuous groove 13 so as not to protrude from the portion of the surrounding pillar concrete 12 Make sure to settle down.

In Figure 1 it can be seen that the anchor 20 consisting of the assembly of bolts, nuts and washers, this anchor 20 is an example proposed to easily install the protective wire mesh 32 to the gabion 33 in a prefabricated manner. . In Figure 1 (a) (c) it can be seen the anchor 20 consisting of the fixing bolt 21, the fixing nut 22 and the fixing washer 23, in Figure 1 (b) further the adjustment nut 24 You can check the anchor 20 configured to include. Fixing washer 23 in the anchor 20 can be prepared in a rectangular plate so as to connect the adjacent anchors at the same time (see Figure 2b). In particular, when the fixing bolt 21 and the fixing nut 22 are assembled in the continuous groove 13 as shown in FIG. 1 (c), the fixing bolt 21 is not exposed, so it is not only aesthetically advantageous but also the passage of pedestrians around the retaining wall. City pedestrians can be prevented by the danger of grazing.

The vegetation mat 31 is arranged to connect between the reinforced concrete pillars 10 in front of the reinforced concrete pillars 10 while being restrained and installed in the anchor 20. The vegetation mat 31 is configured to induce the sticking of the plant. In the present invention, the vegetation mat 31 includes a grass mat as well as a planted form of a herbaceous seed, which is usually applied to a greening method.

Vegetation mat 31 is installed in close contact with the front of the reinforced concrete pillar 10, as shown in Figure 1 (a) (c), as well as appropriately adjust the length of the fixing bolt 21 as shown in Figure 1 (b) In addition, it may be installed at a predetermined distance from the front of the reinforced concrete pillar 10 while using the adjustment nut 24 appropriately.

The protective wire mesh 32 is fixed to the anchor 20 while covering the vegetation mat 31 and protects the vegetation mat 31 and constitutes a retaining wall front surface. After a long time, the vigor of the plant activity is corroded or decomposed vegetation mat 31 is considered in consideration of this can be said that the protective wire mesh 32 substantially maintains the shape of the retaining wall.

The protective wire mesh 32 forms a vegetation space together with the vegetation mat 31, and when the vegetation soil 41 is filled in the vegetation space, the earth pressure by the vegetation soil 41 acts on the protective wire mesh 32. The wire net 32 needs to be prepared from a material having sufficient rigidity to withstand the earth pressure by the vegetation soil 41. In addition, since the front surface of the retaining wall is always exposed to the outside air, the protective wire mesh 32 needs to be made of a material having excellent corrosion resistance. Such materials include expanded metals.

If the front of the reinforced concrete pillar 10 as shown in Figure 1 (a) (b) is to be formed flat, the protective wire mesh 32 may also be provided flat, as shown in Figure 1 (c) reinforced concrete pillar ( 10) If the continuous groove 13 is formed on the front surface of the protective wire mesh 32 will be provided by properly bending to be fixed to the anchor 20 is fitted into the continuous groove (13).

Vegetation soil 41 is a configuration that is filled in the vegetation space formed by the vegetation mat 31 and the protective wire mesh 32, it is a configuration that is the basis of plant growth. That is, it is filled between the slope (S) and the vegetation mat (31).

As soon as the vegetation soil 41 is filled, it is completed as a green retaining wall. 1 (a) (c) is completed with a green retaining wall exposed to the front of the reinforced concrete column 10 as the vegetation soil 41 is filled between the reinforced concrete pillars 10, Figure 1 (b) As the vegetation soil 41 is filled so that the concrete pillar 10 is completely embedded, the retaining wall is completed with a green retaining wall formed as a vegetation environment.

Since the protective wire mesh 32 in the green retaining wall according to the present invention is connected to the reinforced concrete pillar 10 by the anchor 20, the earth pressure by the vegetation soil 41 is finally reinforced through the protective wire mesh 32. Transmitted to the concrete pillar 10 is maintained in a stabilized state. However, minimizing the transmission of earth pressure by the vegetation soil 41 to the protective wire mesh 32 will be preferable for structural stability and efficient structural design of the greening retaining wall. In the present invention, the vegetation as shown in FIG. When the filling area of the toe 30 is large, it is proposed to use the reinforcing grid 42 appropriately.

The reinforcing grid 42 is a structure that is horizontally embedded in the vegetation soil 41, it can be said to be a configuration for separating the vegetation soil 41 between the layers. As the reinforcing grid 42 is installed, the deformation in the lateral direction due to the vegetation soil 41 is suppressed by the friction of the reinforcing grid 42 and the earth and sand particles and the restraint of the reinforcing grid 42 which receives the tensile force. The reinforcing grid 42 may be installed while connecting to the protective wire mesh 32. In this case, since the reinforcing grid 42 is formed to hold the protective wire mesh 32, the filling phenomenon of the protective wire mesh 32 is advantageous. It can suppress (refer FIG. 3 (c)).

On the other hand, in the case of the lakeside slope (S), the lower part of the retaining wall may be submerged according to the water level change. The upper retaining wall is composed of the vegetation mat 31, the protective wire mesh 32, and the vegetation soil 41 as described above, and is completed as the actual green retaining wall, and the lower retaining wall is composed of the gabion 33 and the filling stone 43 It is clarified and provided to the fish habitat (see Figures 2c, 3a).

Gabion 33 is a structure that is fixed to the anchor 20 while connecting the reinforced concrete pillars 10, it is configured to replace the vegetation mat 31 and the protective wire mesh 32 described above. Filling stone 43 is a configuration that is filled between the slope (S) and the gabion 33, it becomes a configuration to replace the vegetation soil 41 described above.

2a to 2d is a construction sequence diagram showing the construction method of the reinforced green retaining wall according to the present invention, Figure 3 shows the process of constructing the filling stone 43 and the vegetation soil 41 step by step. The construction method of the reinforced green retaining wall according to the present invention will be described step by step with reference to these drawings.

(1) the first step-reinforced concrete column and anchor construction step (Fig. 2a and 2b)

The reinforcement concrete pillars 10 are spaced along the slopes S by installing pillar formwork 100 on the stabilized slope surface S, laying the pillar reinforcement 11 and placing the pillar concrete 12. Construct. At this time, the anchor 20 is installed so as to protrude through the front of the pillar formwork 100 is constructed so that the anchor 20 protrudes and fixed to the front of the reinforced concrete pillar (10) (Fig. 2b). The construction method of the reinforced concrete column 10 by the pillar formwork 100 will be described in detail with reference to FIGS.

Stabilized slope (S) is as described above. In FIG. 2A, the nonwoven fabric S2, the drainage plate S3, and the like are treated on the ground surface S1 while being stabilized by sloped reinforcing holes S4 and the foundation F is installed on the lower surface of the slope S. You can check. Depending on the ground conditions, the nonwoven fabric S2, the drainage plate S3, and the foundation F can be omitted, as well as surface treatment with shotcrete S41.

In FIG. 2B, the reinforced concrete column 10 is constructed at the position where the slope-surface reinforcing hole S4 is constructed on the front surface of the drain plate S3 on the foundation F. As shown in FIG. Reinforced concrete column 10 is to determine the placement interval and cross section according to the structural calculation of the retaining wall to be constructed. However, considering the constructability of the reinforced concrete column 10, the reinforced concrete column 10 is preferably arranged so as not to be located in the bent section (such as the curved section bent slope surface) in the slope (S).

(2) 2nd step-recording step (refer to FIG. 2C and FIG. 3)

The vegetation mat 31 and vegetation mat 31 and vegetation mat 31 covering the vegetation mat 31 and the vegetation mat 31 arranged to connect between the reinforced concrete pillars 10 at the front of the reinforced concrete pillar 10 are anchored to the anchor 20. Fixed installation and filling the vegetation soil 41 between the slope (S) and the vegetation mat 31 while filling (Fig. 2c). In the case of distinguishing the upper retaining wall and the lower retaining wall, the gabion 33 is installed to a predetermined height as shown in FIG.

This step may proceed while installing the reinforcing grid 42 as shown in FIG. In this case, the first step is to fill the vegetation soil 41 (Fig. 3 (b)); Laying horizontally the reinforcing grid 42 on the vegetation soil 41 (FIG. 3 (c)); Secondly filling the vegetation soil 41 on the reinforcing grid 42 and compacting (FIG. 3 (d)); Of course, according to the unit height of the vegetation mat 31 and the protective wire mesh 32, the compacting operation and the installation of the reinforcing grid 42 can be repeatedly performed.

(3) Step 3-Repeating Steps (see FIG. 2D)

The greening step (second step) is repeated to the height of the retaining wall to be constructed. In other words, the greening process of the first stage (vegetation mat and protective wire mesh installation and vegetation soil filling) is performed over the entire retaining wall, and the second stage is repeated to the first stage. As a result, as shown in FIG. 2D, a greening retaining wall having a whole or part of the front surface of the vegetation space is completed.

 4 to 7 illustrate a process of constructing the reinforced concrete pillar 10 using the pillar formwork 100 and the pillar formwork 100 proposed in the present invention in order to easily construct the reinforced concrete pillar 10. . The present invention proposes two embodiments for the column formwork 100.

4 is an example consisting of a rear plate 110a and an assembly frame 120 as a first embodiment of the pillar formwork 100. The rear plate 110a is a portion that forms the rear side of the reinforced concrete column 10, and is installed to be placed on the front side of the slope (S). When the drain plate is installed on the slope, the drain plate replaces the rear plate 110a. can do. The assembly frame 120 is a part forming a surface other than the rear surface of the reinforced concrete column 10, and is fixedly installed by the first binding hole 130 on the rear plate 110a while being split in the horizontal direction. The two or more configuration pieces 120a and 120b are assembled by the second binding port 140. As shown in FIG. 4, each of the component pieces 120a and 120b of the assembly frame includes the surface forming portion 121 and the component assembly pieces 120a and 120b for forming the surface of the reinforced concrete column 10. The coupling blades 122, 123 for assembling the rear flat plate 110a of the, and the coupling wings 122, 123 may be provided with the through holes (122a, 123a) for fastening the first and second binding holes as appropriate. . The pillar formwork 100 according to the first embodiment is a method of supporting the buoyancy according to the concrete placing by the binding force of the rear plate 110a and the assembly frame 120, it is also considered to omit the rear plate 110a. Can be. However, if the rear plate 110a is omitted, the assembly frame 120 should be firmly fixed to the slope surface S using an anchor so that the buoyancy received by the assembly frame 120 is safely transferred to the slope surface S. Installation stability of the assembly frame 120 can be secured.

The pillar formwork 100 according to the first embodiment has a structure in which the rear plate 110a supports the buoyancy received by the assembly frame 120, and in particular, the rear plate 110a has a cement paste contained in concrete into the ground. It also acts on the concrete hardening as it does not penetrate, so that the reinforced concrete column 10 can be constructed with design strength. The assembly frame 120 may be provided so as to correspond to the cross-section of the reinforced concrete pillar 10 to be constructed, and in FIG. 4, two component angle pieces 120a and 120b are formed, while one component angle piece 120a is a reinforced concrete column ( 10) It can be seen that the assembly frame 120 made of a form for forming the continuous groove 13 on the front. In addition, in FIG. 4, the first binding holes 130 provided with fixing nails (screws may be used) and the second binding holes 140 provided with bolts and nuts can be confirmed.

5 shows a method of constructing the reinforced concrete pillar 10 using the pillar formwork 100 of FIG. 4, and thus looks at a method of constructing the reinforced concrete pillar 10. First, the rear plate 110a is installed and the pillar formwork 100 is installed while installing some constituent pieces 120a of the assembly frame 120 (FIG. 5 (a)). Then, assembling the remaining component pieces 120b of the assembly frame 120 (FIG. 5 (b)), the pillar concrete 12 is poured into the pillar formwork 100 (FIG. 5 (c)). In the column formwork 100, the rear flat plate 110a may be fixedly installed on the inclined surface S with screws or the like, and may be installed as it is without fixing the rear flat plate 110a. According to the installation stability of the column formwork 100 may be determined. Of course, including the process of reinforcing the column reinforcement 11 in the pillar formwork 100 during the pillar formwork 100 installation process. The pillar concrete 12 may be poured in such a manner as to flow down from the upper surface of the slope (S) by a pump, and may also be compacted by tapping the assembly frame 120 using a wooden hammer or the like. The pillar concrete 12 is filled between the lower plate and the assembly frame 120, and thus the cement paste contained in the pillar concrete 12 acts on the curing of the pillar concrete 12 without being spilled onto the slope (S). do. After the pillar concrete 12 is cured, the mold 100 is demolded and removed from the pillar formwork 100, thereby completing the reinforced concrete pillar 10 (FIG. 5 (d)). As shown in Figure 5 (d) in the column formwork 100, the back plate 110a is not removed and is permanently present.

On the other hand, in Figure 5 (a) it can be seen that the anchor 20 is fixed to the assembly frame 120, this is to anchor the anchor 20 integrally to the reinforced concrete pillar (10). The anchor 20 is fixed to the assembly frame 120 so as to project through the front of the assembly frame 120 of the column formwork. In Figure 5 (a) can be confirmed anchor anchoring the fixing bolt 21 using a pair of nuts properly, and in addition to the reinforcement spacer for reinforcing the column reinforcement 11 in consideration of the reinforcement of the column reinforcement (11) It can be seen that 25 is manufactured integrally with the anchoring bolt 21 of the anchor.

FIG. 6 is an example of a backside shell 110b and an assembly frame 120 as a second embodiment of the pillar formwork 100. FIG. 7 illustrates a reinforced concrete column 10 using the pillar formwork 100 of FIG. Demonstrate how to construct. The pillar formwork according to the second embodiment is the same as the pillar formwork according to the first embodiment described above as a whole, except that the rear shell material 110b is used instead of the rear plate 110a. That is, instead of installing the rear flat plate (110a) in front of the slope (S), a pair of rear lumber (110b) is to be fixed to the slope surface (S) front spaced apart at the rear width interval of the reinforced concrete pillar (10). Unlike the rear flat plate 110a, a pair of such back lumber 110b is directly fixed to the slope, because unlike the rear flat plate 110a, the rear lumber 110b stably supports the concrete buoyancy received by the assembly frame 120. Because I do not support.

The pillar formwork 100 according to the second embodiment may be advantageously applied to the inclined surface S surface-treated with the shotcrete S41 while being reinforced by a small nail. This is because the back corner material 110b may be installed and fixed on the surface of the shotcrete S41 before the shotcrete S41 is cured. Compared with the first embodiment, the second embodiment differs only in that it does not directly form the rear surface of the reinforced concrete pillar 10, and thus, the reinforced concrete in the same manner as the pillar formwork of the first embodiment described above as a whole. The pillar 10 will be constructed.

On the other hand, in Figure 7 (a) it can be confirmed that the column reinforcing bar 11 is installed in the slope slope reinforcing hole (S4). As shown, after connecting the rebar fixing plate S42 to the protruding head of the slope-surface reinforcing hole S4, the reinforcing bar 11a is leaned on the rebar fixing plate S42 and wound around the band reinforcing bars 11b. The column reinforcement 11 is arranged. Such reinforcement can improve the fixing ability for the reinforced concrete pillar 10 of the slope surface reinforcing hole (S4).

The present invention has been described in detail above with reference to specific embodiments, but the embodiments are only for illustrating the present invention, and thus the embodiments substituted, added, and modified within the scope without departing from the spirit of the present invention are also described below.
