[The purpose of the device] [Industrial applications]

 The present invention relates to a stopper for retaining soil, which is used to prevent the soil from flowing out due to rainfall or the like and falling when the soil is sewn on a steep slope of rock or mortar.

[0002]

[Background of device]

 In recent years, in order to maintain the scenery during road construction and riverbank construction, the steep slopes of roadsides and riverbanks caused by the construction are not simply covered with mortar or covered with concrete blocks, but the entire surface. Alternatively, attempts are being made to plant plants such as grass, flowers, and trees in one lot.

On the other hand, when a plant is planted on such a steep slope, it is necessary to cover the steep slope with as thick a soil as possible in order to ensure the establishment of the plant, but the gradient is strong. The higher the risk, the higher the risk of collapse of the soil due to wind and rain, and it will be very difficult to thicken the soil.

In addition, the state of the slope is not uniform, and the surface always has irregularities, and there are various types of slopes such as bedrock and mortar, and their properties vary widely with strong acidity and alkalinity. Depending on the state of the above, it was not possible to make such a dusting of the soil.

[0005]

[Technical items we tried to develop]

 The present invention has been made in view of such a background, and a new soil can be installed even if the slope is steep and the slope is strong, and it can be installed regardless of the state of the slope. It was an attempt to develop a stopper for earth retaining.

[0006]

[Constitution of device]

[Means for achieving the purpose]

 The earth retaining stopper, which is the first idea of the present application, is a member for retaining earth, which is prevented from collapsing on the steep slope, and the member is a stopper plate for directly supporting the soil. The stopper plate is provided with a stopper pin for fixing the stopper plate to a steep slope, and the stopper plate is provided with a through structure that allows the root of a plant planted in the soil to pass through.

In addition to the above requirements, the stopper for earth retaining according to the second invention of the present application has a mesh structure for the stopper plate passage structure, and the stopper pin is a sleeve provided on the mesh body. On the other hand, it is characterized in that it is fitted in a clearance fit state, whereby the relative position with respect to the stopper plate can be adjusted. Then, these means are used to achieve the above object.

[0008]

[Function of the device]

 Since the stopper plate of the earth retaining stopper of the present invention is provided with a through structure, the roots of the plant planted in the soil can pass through the stopper plate and extend downward for a long time. By entwining with the passage structure and lath net, it has a strong effect of preventing the collapse of the soil.

Further, since the stopper pin in the earth retaining stopper of the present invention can be set so that its relative position to the stopper plate can be adjusted freely, even if there is some unevenness in the slope shape, the driving dimension of the stopper pin can be adjusted. By adjusting it, it becomes possible to smoothly thatch the soil.

【Example】

 Hereinafter, the earth retaining stopper according to the present invention will be specifically described with reference to the drawings. The reference numeral 1 in the figure is the earth retaining stopper of the present invention. This stopper is used to pave the soil 3 for slope greening against the steep slope 2 of rock or mortar. , It is used for the purpose of ensuring that roofing and preventing the outflow and collapse of the soil 3.

The earth retaining stopper 1 of the present invention used for such a purpose is composed of a stopper plate 10 and a stopper pin 20, of which the stopper plate 10 is a U-shaped reinforcing bar 11. Is used as a frame member, and a net body 12 is stretched on the reinforcing bar 11. Further, two sleeves 13 are provided on one surface of the net body 12 as shown in FIGS. ing. The stopper plate 10 having a size of 45 cm × 8 cm is used in this embodiment, but the size can be variously changed according to the application.

In addition, in the embodiment shown in FIGS. 4 to 6, the net body 12 constitutes the passing structure in the present invention. In addition to this, as shown in FIG. 7, the metal flat plate 14 is used as the stopper plate. The flat plate 14 may be provided with an opening 15 to form a through structure. As the opening 15 in this case, a large number of holes 16 are provided on the flat plate 14 as shown in FIG. 7A, or a plurality of slotted slits 17 are provided as shown in FIG. 7B. The provided one can be adopted. Further, by using the reinforcing steel bars 11 in the embodiments shown in FIGS. 4 to 6, the round rods 18 having a small diameter are provided in the shape of a slant at regular intervals as shown in FIG. 7 (c). It is also possible to construct a through structure.

On the other hand, the stopper pin 20 is used by being fitted into the sleeve 13 of the stopper plate 10, and is made by appropriately bending the end portion of a round bar having a diameter slightly smaller than the inner diameter of the sleeve 13. Specifically, one end of the round bar is bent into a hook shape to form a locking portion 21, and the other end has a pointed shape to facilitate insertion into the slope 2. There is.

As for the shape of the engaging portion 21 of the stopper pin 20, in addition to this, as shown in FIG. 8A, the end pin diameter of the stopper pin 20 is made somewhat larger to engage with the sleeve 13. Alternatively, the stopper pin 20 may be formed on the peripheral surface of the stopper pin 20 with a notched portion 22 as shown in FIG. 8B. Alternatively, the stopper pin 20 may be a screw-in type. Further, in this case, the sleeve 13 may be screwed.

Then, when the soil retaining stopper 1 of the present invention including the stopper plate 10 and the stopper pin 20 is used to actually pave the soil 3 on the slope 2, the following procedure is performed. That is, first, as shown in FIGS. 1 and 2, a lath mesh 5 is provided on the slope 2 via a spacer 4. Next, the earth retaining stopper 1 of the present invention is staggered as shown in FIG. 3 by driving the stopper pin 20 into the slope 2 (in this embodiment, the vertical spacing is 50 cm and the horizontal spacing is 60 cm). ) Is opened and it is provided in the shape of a shelf with respect to the slope 2. When the stopper pin 20 is driven, the hook-shaped locking portion 21 is driven downward in consideration of safety of work.

Further, the earth retaining stoppers 1 of the present invention are provided in a zigzag manner in this manner. When the earth retaining stoppers 1 are arranged vertically and horizontally, adjacent earth retaining stoppers 1 are arranged. This is to prevent this because the space between them becomes a passageway for water and the collapse of the soil 3 is likely to occur. Further, in the present invention, as an example, a relatively small earth retaining stopper 1 having a width of 45 cm and a depth of 8 cm is used, but this is for facilitating the adjustment of the mounting position according to the unevenness of the surface of the slope 2. Is. Further, for small irregularities on the slope 2, as shown in FIG. 6, the stopper 10 is pressed against the slope 2, so that the end shape of the net 12 is attached so as to match the irregularities on the surface of the slope 2. To

In addition, in the corner portion as shown in FIG. 9 in which the direction of the slope 2 changes abruptly, a corner stopper plate 10 as shown in FIG. 9 can be used. Further, when the slope 2 has very large irregularities, a plurality of earth retaining stoppers 1 may be arranged in parallel as shown in FIG.

When all the earth retaining stoppers 1 are attached, as shown in FIG. 1, the soil for soil 3 is sequentially sewn, and after the soil sewage for soil 3 is completed, plants such as flowers and trees are planted. 6 is planted, and a series of slope greening work is completed.
