Description

The present invention relates to a cage frame unit for stone filling used for coastal and river bank protection, slope protection in mountain areas, etc., a cage frame connection using a plurality of these, and a three-dimensional stacking of the cage frame connection. The present invention relates to a cage frame laminate and a method of constructing a retaining wall using the same.

Traditionally, futon baskets (square gabions) have been stacked in steps and retaining walls have been used for slope protection and greening of slopes in mountains, valleys, roads, residential areas, river banks, etc., and for first aid in times of disaster. There is a technology to form it. These futon baskets are usually box-shaped made of wire mesh, and are made by filling them with large and heavy stones, each weighing about 10 to 100 kg.

Patent Documents 1 and 2 describe futon baskets that prevent overlapping of wire meshes in areas where futon baskets are adjacent to each other, thereby saving members. In Patent Documents 1 and 2, the bottom surface of the upper futon basket is covered with a lid net or the like of the lower futon basket, so the futon basket is not provided with a bottom net for the purpose of saving materials.

However, in Patent Documents 1 and 2, when filling the container with stones and closing the lid, it is necessary to adjust the amount and arrangement of stones. If there are too many stones and they protrude too far above the top of the futon basket, the lid of the futon basket will not close, and even if the lid can be closed, the internal pressure of the futon basket will increase, causing the futon to close. This may lead to damage to the basket. On the other hand, if there are too few stones, the protective effect of the retaining wall as a whole will be reduced, and the weight from above may cause damage to the wire mesh. Therefore, it is necessary to adjust the amount and arrangement of stones packed into the futon baskets, and level them in order to cover them and stack the futon baskets further, but this is a time-consuming process that can be done either by machine or by hand. .

That is, as shown in FIGS. 1 and 2B, the side mesh 22s is a "common wire mesh." In this specification, the "common wire mesh" is defined as a wire mesh arranged on adjacent and mutually opposing surfaces of adjacent cage frame units. The "common wire mesh" has the effect of avoiding overlapping of members on adjacent and mutually opposing surfaces of adjacent cage frame units. The "common wire mesh" can be used not only on the right or left side as viewed in Figure 1, but also on the rear side (back) or the front side (front) as long as there is an adjacent cage frame unit. can be placed.

For example, as shown in combination example 1 in FIG. 7(a), if the space for stone filling surrounded by the main body net and formed by one cage frame unit according to the embodiment is defined as a "unit space", The unit space S can be formed by three L-shaped nets, that is, the L-shaped net 21, the L-shaped net 22a, and the L-shaped net 22b. The L-shaped net 22a and the L-shaped net 22b can each serve as members forming two unit spaces adjacent to the unit space S in FIG. 7(a). Combination example 1 in FIG. 7(a) may appear in a planar connected body of cage frame connected bodies formed in the same plane. Further, as shown in combination example 2 in FIG. 7(b), the unit space S can also be formed by two L-shaped nets, that is, the L-shaped net 21 and the L-shaped net 22a, and the back net 23. . The L-shaped net 22a can be a member forming a unit space adjacent to the unit space S in FIG. 7(b). Combination example 2 in FIG. 7(b) may appear in a cage frame connected body or the like formed by connecting a plurality of cage frame units on the same straight line or on the same curve. Furthermore, as shown in combination example 3 in FIG. 7(c), the unit space S can also be formed by two L-shaped nets, that is, the L-shaped net 21 and the L-shaped net 22b, and the side net 25. . The L-shaped net 22b can be a member forming a unit space adjacent to the unit space S in FIG. 7(c). Combination example 3 in FIG. 7(c) may appear in a cage frame connected body or the like formed by connecting a plurality of cage frame units on the same straight line or on the same curve. Furthermore, as shown in combination example 4 in FIG. 7(d), the unit space S can also be formed by an L-shaped mesh 21, a back surface mesh 23, and a side surface mesh 25. Combination example 4 in FIG. 7(d) may appear in a cage frame connected body or the like formed by connecting a plurality of cage frame units on the same straight line or on the same curve. In addition, in the combination example 4 of FIG.7(d), in order to form the unit space S, it is also possible to use L-shaped net|network instead of the back surface net|network 23 and the side surface net|network 25. As schematically illustrated in FIGS. 7(a) to (d), there are several ways in which the unit space S is formed by the combination of the L-shaped net consisting of two sides and the back and side nets consisting of one side. There is also a street. In addition, in FIGS. 7(a) to (d), in order to clearly show the arrangement of the L-shaped net, the back net, and the side net, the connecting positions of the L-shaped net, the back net, and the side net are intentionally spaced apart for schematic representation. It is illustrated in the figure.

The L-shaped nets 21 forming the unit space S in FIGS. However, the arrangement of the L-shaped net 21 for forming the unit space is not limited to these. For example, the unit space S may be formed by arranging the L-shaped mesh 21 in an L-shape on the right side and front side of a square prism, or may be arranged so as to constitute one surface of the L-shaped net 21 to form the unit space S. The same concept applies to L-shaped networks forming unit spaces such as the L-shaped network 21 in FIGS. 1 and 2A.

In FIG. 1, the coil 41b is illustrated as a member that connects three sides, that is, the back net 23, the side net 22s, and the back net 24 in a T-shape, but this is only an example of how to connect, and it is not necessarily the case. It is not necessary to connect all three sides at once. For example, the back net 23 and the back net 24 may be connected once using the coil 41b shown in FIG. 2E, and the connected body of the back net 23 and the back net 24 and the side net 22s may be connected using another coil. good.

Three third metal wires 33a, 33b, 33c and a fourth metal wire 35a are connected to the lower ends of the back screen 23 and the front screen 21f. The back net 23, the back net 24, and the L-shaped net 22 are connected by a coil 41b, and the L-shaped net 22 and the L-shaped net 21 are connected by a coil 41c. When four rectangular wire meshes corresponding to the four sides of a square prism are connected, a "unit space" is formed inside the four wire meshes. When filling a unit space with stones, as soon as the unit space is formed, stones are filled to about half the height of the unit space as a first stone filling stage. Three third metal wires 33d, 33e, 33f and a fourth metal wire 35b are connected to the upper portions of the back screen 23 and the front screen 21f to form the cage frame unit 11 according to the embodiment. .

For example, the method of connecting the back net 23, the back net 24 and the L-shaped net 22 is Any two members of the net 22 may be connected first, and the connected member and the remaining member may be connected later. In the cage frame unit 11, some or all of the coils 41a, 41b, and 41c used to connect the wire meshes may be omitted. As an alternative to the various coils such as the coils 41a, 41b, and 41c, the wire meshes may be connected using binding wires, various bolts such as U-shaped bolts, or the like. The first metal wire 31a, the second metal wire 31b, the six third metal wires 33a, 33b, 33c, 33d, 33e, 33f, and the two fourth metal wires 35a and 35b are the cage frame unit. In No. 11, a part or all of it may be omitted. Moreover, the stone filling may be performed at once after the cage frame unit 11 according to the embodiment is assembled, without separating it into the first and second stone filling stages. Furthermore, the stone filling may be carried out to a horizontal level below the upper end of the main body net (21f, 21s, 23, 22s), or at a horizontal level below the upper end of the main body net (21f, 21s, 23, 22s). You can go beyond that.

(Retaining wall construction method according to embodiment)
By assembling the cage frame laminate 1 according to the embodiment shown in FIG. 3 and further filling the inside with stones, it is possible to construct a retaining wall according to the embodiment, which has uses such as slope protection, as shown in FIG. 11. can. First, a suction prevention material etc. is laid on the ground where the cage frame laminate 1 is to be installed, and unit spaces S _(1,1,1) , S _(1,1,2) ...S _(1,1, A first cage frame connected body in which a plurality of cage frame units each forming a cage frame unit _n) is connected in a straight line is assembled while filling the inside with stones. Specifically, all of the plurality of cage frame units related to the first cage frame connected body are connected to each other by coils or the like to form each unit space S _(1,1,1) , S _(1,1,2). ...S _{(1, 1, n)} is formed. Various metal wires provided on the bottom surfaces of each cage frame unit are connected, and each cage frame unit is filled with stones to about half the height of each cage frame unit as a first stone filling stage. The remaining various metal wires are connected to the back net of each cage frame unit and the upper part of the L-shaped net, and as a second stone filling stage, the stones are placed on top of the stones that have already been packed to about half the height of the unit space. Next, stones are filled so as to fill each unit space, that is, up to the vicinity of the upper end of each main body net, and the first cage frame connected body filled with stones is completed.

Next, unit spaces S _(2,1,1) , S _(2,1,2) ...S _(2,1,n) are placed on the first cage frame connected body filled with stones. A second cage frame connected body in which a plurality of cage frame units are connected in a straight line is assembled while filling the inside with stones. Specifically, all of the plurality of cage frame units related to the second cage frame connected body are connected to each other with coils or the like to form each unit space S _(2,1,1) , S _(2,1,2). ...S _(2,1,n) is formed. Each time each unit space S _(2,1,1) , S _(2,1,2) ...S _(2,1,n) is formed, a first basket filled with stones is placed during the formation or after the formation is completed. The contact portion between the upper end of the frame connector and the lower end of the second cage frame connector is connected with a separate coil or the like. With respect to the first cage frame connection body filled with stones, the second cage frame connection body is installed shifted to the slope side, and the first cage frame connection body and the second cage frame connection body filled with stones are installed. This creates a step-like shape with the body. Next, the various metal wires provided on the bottom of each cage frame unit of the second cage frame connection body are respectively connected, and in each cage frame unit, the second cage frame connection is performed as the first stone filling stage. Fill the body with stones to about half the height of each cage frame unit. The remaining various metal wires are connected to the upper part of the back mesh and L-shaped mesh of each cage frame unit of the second cage frame connection body, and as the second stone filling stage, about half of the unit space has already been filled. On top of the stones filled to the height, stones are filled so as to fill each unit space, that is, up to the vicinity of the upper end of each main body net, and a second cage frame connected body filled with stones is completed.

The third cage frame connection body is stacked and formed on the second cage frame connection body, similarly to the case of the second cage frame connection body with respect to the first cage frame connection body. The third cage frame connected body is filled with stones in the same manner as the first and second cage frame connected bodies, and the third cage frame connected body filled with stones is completed, and the three-stage cage frame connection is completed. A retaining wall according to an embodiment is constructed of a body. In FIG. 11, the retaining wall according to the embodiment has three stages, but it may have two stages or four or more stages. As shown in the side view of FIG. 11, the suction prevention material 51 is installed on the ground 62 so as to sufficiently cover the area from the site where the first cage frame connection body is installed on the same horizontal plane as the foot of the slope to the shoulder of the slope. A first cage frame connection body containing a unit space S _{(1, 1, n)} and a second cage frame assembly containing a unit space S _{(2, 1, n)} are laid and filled with the filling stones 61 thereon. A third cage frame connection body including the cage frame connection body and the unit space S _(3,1,n) is stacked, and the retaining wall according to the embodiment is constructed. The ground 62 in FIG. 11 may have a slope (slope) excavated in advance and shaped into a stepped shape before the cage frame connected bodies are stacked, or the ground 62 may initially be a slope, but the cage frame is connected to the ground 62. It may be shaped into a step shape by backfilling the back soil for each step of the body. In addition, in FIG. 11, in order to clearly illustrate the usage state of the retaining wall according to the embodiment, the mesh of the main body mesh of each cage frame unit forming a unit space, various metal wires, and coils are omitted from illustration. There is.

In the retaining wall according to the embodiment shown in FIG. 11, a lid net may be provided on the upper surface of the third cage frame link, which is the uppermost cage frame link. In addition, portions of the upper surfaces of the first and second cage frame connectors, which are cage frame connectors other than the top tier, that are exposed without contacting the cage frame connectors in the immediately upper tier are also included. There may be a lid net.

In the retaining wall according to the embodiment shown in FIG. 11, some or all of the wire meshes of the cage frame laminates forming the retaining wall and the coils connecting the cage frame connectors may be omitted. As an alternative to various coils, binding wires, various bolts such as U-shaped bolts, etc. may be used for connection. Some or all of the various metal wires in the cage frame laminate forming the retaining wall may be omitted.

When constructing a retaining wall for slope protection etc. using the cage frame unit 11 according to the embodiment of the present invention, the effort of leveling the ground and paving stones on which each cage frame unit is installed is significantly reduced compared to the conventional technology. It can be reduced. Some of the conventional techniques always include a bottom net or a lid net, and when installing a bottom net or a lid net, it is always necessary to adjust the unevenness of the installation location. If the horizontal surface remains uneven when installing the bottom net, the entire cage frame unit including the bottom net will be tilted or distorted, making it difficult to connect with other cage frame units, and causing the slope This may cause problems in the construction of the entire protective retaining wall. In addition, if the horizontal surface on which the lid is placed is uneven when installing the lid net, the lid net will be distorted and uneven, which may cause problems when installing the cage frame units to be stacked next. . Furthermore, if the horizontal surface on which the lid is placed becomes uneven due to too much filling stones in the cage frame unit, unnecessary tension will be applied to the lid net etc., which may lead to damage to the cage frame unit itself. When constructing a retaining wall for slope protection etc. using the cage frame unit according to the embodiment of the present invention, there is no bottom netting or cover netting, so each cage frame unit has to be used for unevenness adjustment. Only minor adjustments are required to install the various metal wires provided on the frame line and bottom of the main body net, which can greatly save time and effort. When filling stones, there is no need to be too careful about the amount and placement of stones. Even if the amount of filling stones in a lower cage frame unit is somewhat large, it is not necessary to be too careful about the amount and placement of stones. It is possible to reduce the amount of filling stones to some extent and adjust the amount and arrangement of the filling stones to be appropriate for the retaining wall as a whole. On the other hand, even if the amount of filling stones in the lower cage frame unit is somewhat small, the amount of filling stones in the adjacent upper cage frame unit can be slightly increased, and the amount of filling stones for the entire retaining wall can be increased. It is possible to adjust the position and arrangement to be appropriate. In other words, the effort and time required to adjust the amount and arrangement of filling stones in each cage frame unit can be greatly reduced. For these reasons, the cage frame unit, the cage frame connection body, and the cage frame laminate can be installed more quickly.

When constructing a retaining wall for slope protection etc. using the cage frame unit 11 according to the embodiment of the present invention, fewer members are used than in the prior art, so the cage frame unit, the cage frame connection body, and the cage frame Installation of the laminate can be done faster and costs can be reduced overall. Furthermore, since the number of members is smaller than in the prior art, it is easier to maintain the members after constructing a retaining wall for slope protection, etc. After a while after constructing a retaining wall, the stones may tighten together or the ground may sink slightly, causing the stones to fall downward as a whole. Maintenance can be facilitated by replenishing filling stones from the open upper surface side of each cage frame unit of the uppermost cage frame connected body. Further, it is also possible to replenish filling stones from the open and exposed upper surface portion of each cage frame unit of the cage frame connected bodies other than the top row.

When constructing a retaining wall for slope protection etc. using the cage frame unit 11 according to the embodiment of the present invention, there is less overlap of members and there is no cover netting or bottom netting, so the number of coil connection points is naturally reduced. do. Thereby, the cage frame unit, the cage frame connected body, and the cage frame laminate can be installed more quickly, and the cost can be reduced overall.

When constructing a retaining wall for slope protection etc. using the cage frame unit 11 according to the embodiment of the present invention, since it does not have a cover net or a bottom net, it is difficult to prevent filling of stones between the upper and lower cage frame units. This causes both interlocking and the digging of the stones into the ground where the retaining wall is installed. Some of the conventional techniques always have a bottom net or a lid net, and at least one of the jamming stones between the upper and lower cage frame units or the digging of the filling stones into the ground where the retaining wall is installed occurs. do not have. In particular, the weight of the stones on the upper level is applied to the lower level of the retaining wall, so the interlocking of the stones between the cage frame units on the lower level of the retaining wall and the installation of the retaining wall. The filling stones that dig into the ground are extremely heavy in maintaining the strength of the retaining wall. In addition, when a suction prevention material is used, the filling stones dig into the ground where the retaining wall is installed through the suction prevention material.

When a retaining wall for slope protection etc. is constructed using the cage frame unit 11 according to the embodiment of the present invention, and when various metal wires are used as shown in FIG. It is possible to prevent problems such as the jamming of the cage frame unit 11 and the strength of the cage frame unit 11 and the retaining wall itself. In particular, when the first metal wire 31a and the second metal wire 31b shown in FIGS. 1 and 2I are used as various metal wires, horizontal distortion of the cage frame unit 11 can be reduced or prevented. In addition, it is possible to reduce or prevent the filling stones from sinking, particularly in the central portion of the cage frame unit 11. The center of gravity of the cage frame unit 11 filled with stones is the center of the unit space, and the weight of the stones is particularly applied downward from the center. Here, by reducing or preventing the sinking of the filling stones in the center of the cage frame unit 11, it is possible to effectively reduce or prevent the sinking of the filling stones in the entire cage frame unit 11. Distortion and damage to the entire structure of a retaining wall for slope protection etc. using a plurality of frame units 11 can be prevented. As shown in FIG. 1, when the cage frame unit 11 has the first metal wire 31a and the second metal wire 31b, on the bottom surface of the cage frame unit 11, the first metal wire 31a and the second metal wire The effect of preventing the filling stone from sinking near the intersection of the lines 31b can be particularly increased. As the distance between the first metal wire 31a and the second metal wire 31b increases radially outward from the intersection of the first metal wire 31a and the second metal wire 31b, the distance between the first metal wire 31a and the second metal wire 31b increases. The proportion of the filling stones that come into contact with either or both of the metal wire 31a and the second metal wire 31b is reduced. Therefore, the effect of preventing the filling stones from sinking decreases radially outward from the intersection of the first metal wire 31a and the second metal wire 31b. The intersection of the wire rods 31b is the largest. Also in the cage frame units 12 to 17 shown in FIGS. 8 to 10, which will be described later, the first metal wire 31a and the second metal wire 31b are used as various metal wires, similar to the cage frame unit 11 shown in FIG. In this case, it is possible to reduce or prevent distortion of the cage frame unit in the horizontal direction, and it is also possible to reduce or prevent sinking of stones, particularly in the central portion of the cage frame unit.

When the third metal wire 33b shown in FIGS. 1 and 2F is further used as various metal wires in addition to the first metal wire 31a and the second metal wire 31b shown in FIGS. 1 and 2I, the cage frame It is possible to further reduce or prevent distortion of the unit 11 in the horizontal direction, and it is also possible to further reduce or prevent sinking of filling stones, particularly in the central portion of the cage frame unit 11. When the third metal wire 33b is used in the cage frame unit 11, the third metal wire 33b further intersects the intersection of the first metal wire 31a and the second metal wire 31b. The distance between any two of the three metal wires increases as you go radially outward from the intersection of the three metal wires, so any one of the three metal wires, any two of the three metal wires Alternatively, the proportion of stones that come into contact with all three bars will be reduced. Therefore, the effect of preventing the filling stones from sinking decreases radially outward from the intersection of the three metal wires, and is greatest at the intersection of the three metal wires. In the cage frame units 12 to 17 shown in FIGS. 8 to 10, which will be described later, as well as in the cage frame units 12 to 17 shown in FIG. 31a and the second metal wire 31b, if the third metal wire 33b shown in FIGS. 1 and 2F is further used, the horizontal distortion of the cage frame unit can be further reduced or prevented, and , it is possible to further reduce or prevent the sinking of filling stones, particularly in the central portion of the cage frame unit.

When constructing a retaining wall for protecting a slope using the cage frame unit 11 according to the embodiment of the present invention, it becomes possible to construct the retaining wall at the installation location and fill it with stones on the spot. This eliminates the need to suspend a basket frame unit (futon basket, etc.) filled with stones in advance using heavy machinery such as a crane, and thus eliminates the need for heavy machinery such as a crane. Furthermore, since the cage frame unit itself is not suspended by heavy equipment such as a crane, it is possible to prevent the cage frame unit itself from becoming distorted before installation.

When constructing a retaining wall for slope protection etc. using the cage frame unit 11 according to the embodiment of the present invention, each member involved in constructing the retaining wall is small, so transportation costs can also be reduced. Even regarding the L-shaped net, which is the largest member, multiple L-shaped nets can be stacked and transported, which greatly contributes to reducing transportation costs.

When constructing a retaining wall for slope protection etc. using the cage frame unit 11 according to the embodiment of the present invention, the member can be used even for a curved slope having a slope slope having a concave or convex planar shape. It is possible to construct a retaining wall while minimizing the excess or deficiency of. For example, as shown in FIG. 12(a), a cage frame that forms a plurality of unit spaces S _(1,1,1) , S _(1,1,2), etc. whose central axis in the longitudinal direction forms a curve The connecting body 4 is convex upward in FIG. 12(a). In FIG. 12(a), a curved slope is located above the cage frame connected body 4. When each unit space of the cage frame connected body 4 is formed from an L-shaped mesh, a back mesh, and a side mesh that constitutes the L-shaped mesh of the adjacent unit spaces, that is, combination example 2 shown in FIG. 7(b). In the same case, if the width of the back mesh is relatively longer than the width of the front mesh of the two sides of the L-shaped mesh, the cage frame connected body 4 as shown in FIG. 12(a) It is easy to form the overall shape. Depending on the curvature of the curved slope, the width of the back net is adjusted as appropriate, or the width of the front net of the two sides of the L-shaped net is adjusted as appropriate. The width of the back net may be increased by adding a net member to the back net, or the width of the front net may be shortened by cutting the ends of the front net. At this time, the plurality of unit spaces S _(1,1,1) , S _(1,1,2) , . . . have a trapezoidal shape when viewed from above, as shown in FIG. 12(a). In particular, as shown in Fig. 12(a), when the two sides of the L-shaped network intersect at right angles, the unit spaces S _{(1, 1, 1)} , S _{(1, 1, 2)} , etc. are viewed from above. The shape is a right-angled trapezoid. A basket frame laminate is constructed by stacking multiple cage frame connectors similar to the cage frame connector 4 shown in Fig. 12(a), and a retaining wall for slope protection etc. is constructed by filling the inside with stones. can do.

In addition, in FIG. 12(a), the bent part of the L-shaped network of adjacent unit spaces, that is, the lower left corner of the right trapezoid that is the shape of the unit space S _{(1, 1, 2)} seen from above, is The connection may be made so as to fit into the unit space S _{(1, 1, 1)} . For example, if the widths of the front mesh and the back mesh of the L-shaped mesh forming the unit space are the same, and when installing the cage frame connected body on a curved slope, the unit space S _{(1, 1, 1)} , the bent part of the L-shaped network that forms the unit space S _{(1, 1, 2} ) (lower left corner of the right trapezoid) bites in a little bit, and the unit space S _{(1, 1, 2)} is formed from the bent part. It is connected to the front network of the unit space S _{(1, 1, 1)} at a part slightly closer to the front network side. In this case, there is no need to adjust the widths of the front and back meshes of the L-shaped mesh forming the unit space, and the installation can be done more quickly and efficiently. Even if a part of the main body mesh that forms an adjacent unit space digs into a certain unit space, it can be avoided by selecting metal wires of appropriate length for the cage frame unit that forms the unit space. It works well and does not have a big impact on stone filling.

For example, as shown in FIG. 12(b), a cage that forms a plurality of unit spaces S _{(1, 1, 1)} , S _{(1, 1, 2)} , etc. whose central axis in the longitudinal direction forms a curve The frame connecting body 5 is convex downward in FIG. 12(b). In FIG. 12(b), a curved slope is located above the cage frame connected body 5. When each unit space of the cage frame connected body 5 is formed from an L-shaped mesh, a back mesh, and a side mesh that constitutes the L-shaped mesh of the adjacent unit spaces, that is, combination example 2 shown in FIG. 7(b). In the same case, if the width of the back mesh is relatively shorter than the width of the front mesh of the two sides of the L-shaped mesh, the cage frame connected body as shown in FIG. 12(b) It is easy to form the overall shape of 5. Depending on the curvature of the curved slope, the width of the back net is adjusted as appropriate, or the width of the front net of the two sides of the L-shaped net is adjusted as appropriate. The width of the front net may be increased by adding a net member to the front net, or the width of the back net may be shortened by cutting the ends of the back net. At this time, the plurality of unit spaces S _(1,1,1) , S _(1,1,2) , . . . have a trapezoidal shape when viewed from above, as shown in FIG. 12(b). In particular, as shown in Fig. 12(b), when the two sides of the L-shaped network intersect at right angles, the unit spaces S _{(1, 1, 1)} , S _{(1, 1, 2)} , etc. are viewed from above. The shape is a right-angled trapezoid. A basket frame stack is constructed by stacking multiple cage frame connectors similar to the cage frame connector 5 shown in FIG. 12(b), and a retaining wall for slope protection etc. is constructed by filling the inside with stones. can do.

In addition, in FIG. 12(b), the connecting part between the L-shaped net and the back net that form the unit space S _{(1, 1, 2)} , that is, the unit space S _{(1, 1, 2)} is viewed from above. _The connection may be such that the upper left corner of the right-angled trapezoid, which has a shape of For example, if the widths of the front mesh and the back mesh of the L-shaped mesh forming the unit space are the same, and when installing the cage frame connected body on a curved slope, the unit space S _{(1, 1, 1)} , the connecting part between the L-shaped mesh and the back surface mesh forming the unit space S _{(1, 1, 2)} (the upper left corner of the right trapezoid) bites in a little, and the unit space S _{( 1, 1, 2)} is connected to the back surface mesh of the unit space S _{(1, 1, 1)} . In this case, there is no need to adjust the widths of the front and back meshes of the L-shaped mesh forming the unit space, and the installation can be done more quickly and efficiently. Even if a part of the main body mesh that forms an adjacent unit space digs into a certain unit space, it can be avoided by selecting metal wires of appropriate length for the cage frame unit that forms the unit space. It works well and does not have a big impact on stone filling.

(Cage frame unit according to the first modification of the embodiment)
As shown in FIG. 8(a), in the cage frame unit 12 according to the first modification of the embodiment of the present invention, like the cage frame unit 11 according to the embodiment shown in FIG. Wire nets, that is, a front net 21f, a side net 21s, a back net 23, and a side net 22s are arranged at positions corresponding to the four sides of the quadrangular prism. The front net 21f, the side net 21s, the back net 23, and the side net 22s constitute a main body net (21f, 21s, 23, 22s). The structure of the main body net (21f, 21s, 23, 22s) of the cage frame unit 12 according to the first modification of the embodiment is the same as that of the cage frame unit 11 according to the embodiment shown in FIG. 1 and the like. In addition, in FIG. 8(a), illustration of the coil is omitted in order to simplify the illustration and to clarify the structural difference from the cage frame unit 11 according to the embodiment shown in FIG. 1 etc. Regarding the coils used to connect each wire mesh, part or all of the coils may be omitted in the cage frame unit 12. As an alternative to various coils, wire meshes may be connected using binding wires, various bolts such as U-shaped bolts, and the like. Moreover, in the cage frame unit 12 according to the first modification of the embodiment shown in FIG. 8(a), the fourth metal wire provided at the corner may or may not be provided.

Furthermore, as shown in FIG. 8(a), in the cage frame unit 12 according to the first modification of the embodiment of the present invention, the main body net ( 21f, 21s, 23, 22s) have a first metal wire 31a and a second metal wire 31b, both ends of which are fixed. The first metal wire 31a and the second metal wire 31b of the cage frame unit 12 according to the first modification of the embodiment are the first metal wires of the cage frame unit 11 according to the embodiment shown in FIG. 1 etc. 31a and the second metal wire 31b have the same structure and the like.

As shown in FIG. 8(a), in the cage frame unit 12 according to the first modification of the embodiment of the present invention, compared to the cage frame unit 11 according to the embodiment shown in FIG. The number of metal wires is different. The cage frame unit 12 according to the first modification of the embodiment includes a third metal wire 33e that connects the upper portions of the front net 21f and the back net 23 to each other.

When constructing a retaining wall for slope protection etc. using the cage frame unit 12 according to the first modification of the embodiment of the present invention, the same as in the case of the cage frame unit 11 according to the embodiment shown in FIG. 1 etc. Compared to conventional technology, the effort required to level the ground and boulders on which each cage frame unit is installed can be significantly reduced. When constructing a retaining wall for slope protection etc. using the cage frame unit 12 according to the first modification of the embodiment of the present invention, there is no bottom netting or cover netting, so unevenness adjustment is required for each. In order to install the various metal wires provided on the frame line and bottom surface of the main body mesh of the cage frame unit, only minor adjustments are required, and it is possible to greatly save time and effort. When filling stones, there is no need to be too careful about the amount and placement of stones. Even if the amount of filling stones in a lower cage frame unit is somewhat large, it is not necessary to be too careful about the amount and placement of stones. It is possible to reduce the amount of filling stones to some extent and adjust the amount and arrangement of the filling stones to be appropriate for the retaining wall as a whole. On the other hand, even if the amount of filling stones in the lower cage frame unit is somewhat small, the amount of filling stones in the adjacent upper cage frame unit can be slightly increased, and the amount of filling stones for the entire retaining wall can be increased. It is possible to adjust the position and arrangement to be appropriate. In other words, the effort and time required to adjust the amount and arrangement of filling stones in each cage frame unit can be greatly reduced. For these reasons, the cage frame unit, the cage frame connection body, and the cage frame laminate can be installed more quickly.

When a retaining wall for slope protection etc. is constructed using the cage frame unit 12 according to the first modification of the embodiment of the present invention, in the case of the cage frame unit 11 according to the prior art and the embodiment shown in FIG. 1 etc. Since fewer members are used, the cage frame unit, the cage frame connection body, and the cage frame laminate can be installed more quickly, and the cost can be reduced overall.
