Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a retaining basket used for earth retaining work.

[Prior Art] In recent years, with the increase in land development, the demand for earth retaining construction has rapidly increased. As shown in Figure 4, such earth retaining work uses earth retaining baskets called gabions filled with earth and stones; As a result of changes in the ground, the earth retaining basket moves or tilts, causing deformation and damage, which tends to cause the earth retaining function to be lost. In particular, this type of retaining basket often has its sides tilted and flattened by forces from above and below, or is crushed into a parallelogram shape by forces from diagonally on the side. It is desired that earth retaining baskets with high strength against the force of

[Problems to be solved by the invention] The problem to be solved by the invention is to prevent the structure from becoming easily flattened or becoming parallelogram-shaped even when a force is applied from above and below or from a side diagonal direction. ,
Our goal is to provide earth retaining baskets with great strength.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a basket body having at least a bottom piece, a front piece, a rear piece, and left and right side pieces, and a frame rib having a rectangular shape. It is characterized in that a reinforcing frame made of diagonally stretched tension bones is attached diagonally between the front piece and the back piece.

[Operation] When installing a retaining basket, the retaining basket is placed at a predetermined location such as a slope, and its interior is filled with earth and sand, stones, etc. by an appropriate method.

Here, if a vertical force is applied to the earth retaining cage due to filled earth, sand, stones, etc. or due to movement of the slope, etc., the diagonal corner of the cage body within the frame bones of the reinforcing frame The supporting force of the frame bones facing in the direction prevents it from flattening, and when a force in the side diagonal direction is applied to the retaining basket, the diagonal force bones in the reinforcing frame prevent it from flattening. prevention.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

As can be seen from the exploded view shown in FIG. 1 and the perspective view of the assembled state shown in FIG. It consists of 3.

The basket body 2 includes a bottom piece 2a made of a suitable wire mesh, left and right side pieces 2b, 2b, a front piece 2c, a rear piece 2d, and an upper piece 2e, each of which has a bottom piece 2a made of a suitable wire mesh.
Bone lines 5 and 6 are attached to the boundaries or ridges of e, respectively. Each of these pieces 2a to 2e may be formed independently and connected to each other, but some pieces may be formed integrally by bending a piece of wire mesh, and other pieces may be formed into one piece. It may be attached.

In addition, the above-mentioned upper piece 2e is not necessarily necessary,
It can be installed as necessary while considering the installation conditions of the earth retaining basket 1.

Any wire mesh can be used as the wire mesh, such as rhombic wire mesh, welded wire mesh, expanded metal wire mesh, etc., and one type or a combination of multiple types can be used for each piece, but especially in the case of the front piece 2c. Since they are often installed exposed on slopes and do not like bulging deformation, it is desirable to use wire mesh with high rigidity such as welded wire mesh or expanded metal wire mesh.

Further, the reinforcing frame 3 has reinforcing bones 3c, 3c diagonally attached inside frame bones 3a, 3b having a square shape, and these frame bones 3a, 3
b and the force bones 3c, 3c are formed of wire having a sufficiently higher strength than the bone lines 5, 6, bars of various cross-sectional shapes, or the like.

Thus, the retaining basket 1 has the reinforcing frame 3 disposed diagonally between the front piece 2c and the rear piece 2d of the basket body 2, and the frame ribs 3a, 3a are aligned with the bone line of the basket body 2. 5 and 5 with appropriate connecting fittings, it is assembled into the state shown in FIGS. 2 and 3.

The earth retaining basket 1 having the above structure is placed at a predetermined location such as a slope, and by filling it with earth, sand, gravel, etc., it can be stacked in one stage or in multiple stages as shown in Fig. 4. Install. At this time, each retaining basket 1 is attached to the lower end portion of the rear piece 2d, that is, the reinforcing frame 3
The frame ribs 3a on the rear side are fixed in the ground with appropriate fasteners 8. In addition, if the retaining basket 1 has an upper piece 2e, the upper piece 2e is left open and filled with earth and sand, stones, etc., and then closed, and the mesh of the front piece 2c is If it is difficult to support earth, sand, stones, etc. due to the large size of the front piece 2c, an inner mesh 7 with a small mesh size is provided inside the front piece 2c, as shown in FIG. In this case, the lower end 7a of the inner mesh 7
It is preferable to bend it towards the rear.

Here, if movement or erosion of the slope occurs, each retaining cage 1 will tilt around the fixed frame frame 3a, as shown in FIG. Overall, it does not slide along the slope, and there is little risk of losing its earth retaining function. In addition, when force is applied to the earth retaining basket 1 from above and below due to stacking or tilting of the earth retaining basket 1, among the frame ribs 3a and 3b of the reinforcing frame 3,
The supporting force of the frame ribs 3b on the diagonally facing sides of the basket body 2 prevents it from becoming flattened, and when a force in the diagonal direction on the side surface acts on the retaining basket 1,
The reinforcing frame 3 is prevented from forming into a parallelogram by the diagonally extending reinforcing bones 3c, 3c.

FIG. 6 shows another embodiment of the earth retaining basket 11 of the present invention.
2 is a first cage member 13 consisting of a bottom piece 13a, a front piece 13b, and triangular side pieces 13c, 13c.
and a second cage member 14 consisting of an upper piece 14a, a rear piece 14b, and triangular side pieces 14c, 14c.When assembling the retaining cage 1,
These cage members 13 and 14 are turned in opposite directions to each other as shown in the figure, and overlapped as shown in FIG. 15a, 15b, the bone lines 16, 1 of the cage members 13, 14 that overlap therewith.
7 are connected by appropriate connecting fittings 18.

In this case, the triangular side pieces 13 and 14 of the cage members 13 and 14 may be individually stretched with wire mesh, but the two cage members 1
After connecting 3 and 14, 2 is connected in a rectangular shape.
One wire mesh may be stretched over the two side pieces 13c and 14c.

In each of the above embodiments, the front pieces 2c, 1 of the earth retaining basket 1 are
3b and the rear pieces 2d and 14b are vertical, but even if the front piece 20 is inclined as shown in FIG. 8, or the front piece 21 is tilted as shown in FIG.
Both the rear piece 22 and the rear piece 22 may be inclined, and the angle of inclination thereof is set as appropriate depending on the situation at the site.

[Effects of the invention] As described above, according to the dome basket of the present invention, the reinforcing frame, which is made by diagonally extending the reinforcing bones inside the rectangular frame bones, is attached to the front and rear pieces of the basket body. Since it is installed diagonally between the reinforcing frames, even if a vertical force is applied to the retaining cage due to filled earth, sand, stones, etc. or due to movement of a slope, the inside of the frame bones in the reinforcing frame will not be affected. , the supporting force of the frame bones pointing in the diagonal direction of the cage body can prevent it from becoming flattened, and when a force in the side diagonal direction is applied to the retaining cage, the diagonal direction of the reinforcing frame can be prevented. Parallelogram formation can be prevented by the force bones.
