Description

[Detailed description of the invention] [Industrial applications]

[0001] The present invention relates to a legal frame apparatus for greening a lining slope covered with spraying mortar, spraying concrete or the like.

[0002]

2. Description of the Related Art There is known a coating method for spraying mortar or concrete onto a slope to stabilize the slope in order to prevent weathering and collapse of the rock. Also, as one of the slope stabilization methods, a vegetation method is known in which a slope is constructed on a slope, the slope is covered with soil called so-called soil, and then seeds and plants are planted on the soil.

[0003]

[Problems to be Solved by the Invention] The conventional slope stabilization method described above has the following problems.

<B> If the sprayed mortar or sprayed concrete covering the slope is exposed, not only the scenery is damaged, but also there is a risk of collapse due to aging.

<B> Since the various frame devices used in the conventional vegetation method have been developed for the exposed ground, a known frame device is used on a slope where mortar or concrete is covered. It cannot be applied as it is.

[0006]

[Purpose of the present invention] The present invention has been made to solve the above-mentioned problems. The purpose of the present invention is to improve the workability and to reduce the slope covered with a lining layer such as mortar or concrete. It is an object of the present invention to provide a law frame device for lining slope greening that can achieve greening of an object.

[0007]

Means for Solving the Problems The present invention is directed to a lining slope greening method frame apparatus used for a slope greening method for landscaping on the surface of a sloping lining layer. It is characterized by comprising a horizontal net standing upright on the surface in the horizontal direction, a support frame having a polygonal shape that supports the middle of the horizontal net at regular intervals, and a fixing pin for fixing each support frame to the lining layer. It is a law frame device for lining slope greening

[0008]

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings.

<A> Law frame apparatus FIG. 1 shows an example of the law frame apparatus of the present invention. The legal frame device is composed of a horizontal net 1 erected on the slope in the horizontal direction, a plurality of support frames 2 for supporting the horizontal net 1, and fixing pins 3 for fixing each support frame 2 to the lining surface of the slope.

<B> Horizontal Net The horizontal net 1 is a perforated body having a band shape, and various known materials having water permeability and appropriate flexibility such as a known crimped wire mesh and expanded metal can be used.

<C> Support Frame The support frame 2 is formed by bending a single thin plate into a substantially triangular shape.
A rigid frame having three sides of a short oblique side 22 and a long oblique side 22, and pin holes 2 for inserting fixed pins at both ends of a base 21 and a long oblique side 23.
4 are drilled respectively. The entire length of the short oblique side 22 of the support frame 2 is set to a size that can accommodate the horizontal net 1. The shape of the support frame 2 is not limited to a substantially triangular shape, but may be a polygon such as a quadrangle.

<D> Fixing Pin The fixing pin 3 is a known anchor pin, and its total length is determined in consideration of the inclination angle of the site, the type of lining, the soil quality, and the like.

[0013]

Next, the construction method will be described.

<A> Laying of water-permeable mat (FIG. 2) A water-permeable mat 5 is laid on the surface of the lining layer 4 such as mortar or concrete. The water-permeable mat 5 is a member located on the surface of the lining layer 4 and having both a drainage function and a water supply function, and a commercially available product such as a sponge can be used.

<B> Laying the Net (FIG. 2) Next, the net 6 is laid on the surface of the water-permeable mat 5, and the auxiliary pins 7 are driven in from the surface side of the net 6 so that the water-permeable mat 5
And the net 6 are temporarily fixed. As the net 6, various known wire nets and resin nets can be used.

<C> Set of legal frames (FIG. 3) The horizontal net 1 is transported to the surface of the net 6, and the support frame 2 is externally provided at regular intervals on the side of the horizontal net 1 arranged in the horizontal direction. The support frame 2 is fixed with the fixing pins 3. Using each of the support frames 2 and the fixing pins 3, the horizontal net 1 erected in the horizontal direction with respect to the slope is assembled in multiple stages. A water supply rope 8 that is continuous in parallel with the setting of the legal frame is attached in the vertical and horizontal directions on the surface of the net 6. The water supply ropes 8 are attached to the net 6 at appropriate intervals. The water supply rope 8 is a member for supplying water to the soil when the sun is shining, and is formed by covering the outer periphery of a core material made of acrylic fiber with a polymer film and swelling by absorbing water.

<D> Soil (FIG. 4) Finally, the soil 9 until the net 6, the support frame 2 and the horizontal net 1 are hidden.
To complete the construction. As a vegetation method, a method in which seeds and fertilizer are mixed in the soil 9 or a method of planting plants after the construction of the soil 9 is completed can be adopted. The weight of the soil 9 acting on the horizontal net 1 is supported by the support frame 2 via the fixing pins 3.

<E> During drainage In FIG. 4, rainfall that has infiltrated the soil 9 is absorbed by the water supply rope 8. Further, the rainwater that has penetrated to a deep portion of the soil 9 permeates into the permeable mat 5 and flows down along the permeable mat 4. If the water-permeable mat 5 does not exist, rainfall may flow down the surface of the lining layer 4 and the lower layer of the soil 9 may be washed away.
However, between the lining layer 4 and the soil 9, the permeable mat 5
, A drainage channel is formed inside the water-permeable mat 5, and the above-mentioned flow of the soil 9 can be effectively prevented.

<F> Sunshine Since the soil 9 is formed on the surface of the non-permeable lining layer 4, the moisture in the soil 9 is depleted when sunny weather continues for many days. In such a situation, water is supplied from the water supply rope 8 buried in the soil 9 to the soil 9. When the water-permeable mat 5 contains water, the water-permeable mat 5
Since water is supplied to the plant, a suitable growth environment for the plant can be maintained even when the sunshine continues for a long period of time.

[0020]

[Other Embodiments] The above embodiment has been described on the assumption that the lining layer 4 such as sprayed mortar or sprayed concrete covers the ground. May be constructed.

[0021]

[Effects of the Invention] Since the present invention has been described above, the following effects can be obtained.

<A> The legal frame device can be assembled by a simple operation of restraining the middle of the horizontal net with a lightweight support frame and fixing the support frame with pins, so that it can be easily constructed even on a steep slope. it can. In particular, greening can be achieved for an existing spray mortar or a lining layer covered with sprayed concrete, which has been difficult to green.

<B> If a water-permeable mat is laid on the surface of the lining layer, the water-permeable mat forms a drainage channel, and the flow of the soil can be effectively prevented.

<C> By arranging a water-permeable mat or a water supply rope on the surface of the lining layer, not only the water retention performance of the soil can be improved, but also a good vegetation environment can be provided for a long time because water can be supplied into the soil. Can last.

<D> Since the shape is simple, it is suitable for mass production and the production cost of the legal frame can be reduced.
