Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a method frame device for greening a lining slope covered with sprayed mortar or sprayed concrete.

[0002]

[Prior art]

 A coating method is known in which mortar or concrete is sprayed onto the slope to stabilize the slope in order to prevent weathering or collapse of the bedrock. As one of the slope stabilization methods, there is also known a vegetation method in which after constructing a legal framework on the slope, the slope is covered with sediment called soil and then seeds and plants are planted in the soil.

[0003]

[Problems to be solved by the device]

 The conventional slope stabilization method described above has the following problems.

<B> If the sprayed mortar or sprayed concrete that covers the slope is exposed, it not only spoils the scenery, but also risk of collapse due to deterioration.

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

[0006]

[Purpose of the present invention]

 The present invention was made in order to solve the above problems, and its purpose is to have excellent workability and to target revegetation on slopes covered with a lining layer such as mortar or concrete. An object is to provide a legal frame device for greening a lining slope.

[0007]

[Means for Solving the Problems] The present invention relates to a slope frame greening method used for a slope greening method in which soil is planted on the surface of a sloping lining layer for greening. It is composed of horizontal nets erected on the surface of the horizontal direction, polygonal support frames that support the middle of the horizontal nets at regular intervals, and fixing pins that fix each support frame to the lining layer. It is a characteristic framing device for greening slopes on linings.

[0008]

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

<B> Law Frame Device FIG. 1 shows an example of the law frame device of the present invention. The framing device is composed of a horizontal net 1 standing upright on a slope, a plurality of support frames 2 for supporting the horizontal net 1, and a fixing pin 3 for fixing each support frame 2 to the sloped lining surface. .

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

<C> Support Frame The support frame 2 is a rigid frame formed by bending a single thin plate into a substantially triangular shape, and has three sides of a base 21, a short hypotenuse 22 and a long hypotenuse 22. Pin holes 24 for inserting fixed pins are formed at both ends of the pin 23, respectively. The entire length of the short hypotenuse 22 of the support frame 2 is set to a size capable of accommodating the horizontal net 1. The shape of the support frame 2 is not limited to a substantially triangular shape, but may be a polygonal shape such as a quadrangle, as long as it can accommodate and support the horizontal net 1.

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

[Action]

 Next, the construction method will be described.

<A> Laying a 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 that is located on the surface of the lining layer 4 and has 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 pin 7 is driven from the surface side of the net 6 to temporarily fix the water-permeable mat 5 and the net 6. To do. As the net 6, various known wire nets, resin nets and the like can be used.

<C> Set of method frames (FIG. 3) The horizontal nets 1 are carried on the surface of the net 6, and the support frames 2 are mounted on the horizontal nets 1 arranged in the horizontal direction at regular intervals. The support frame 2 is fixed with the fixing pins 3. Using each support frame 2 and the fixing pin 3, the horizontal net 1 standing upright in the horizontal direction with respect to the slope is assembled in multiple stages. In parallel with the work of setting the method frame, the continuous water supply rope 8 is attached to the surface of the net 6 in the vertical and horizontal directions. The water supply ropes 8 are bound and 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. The water supply rope 8 is a rope which is formed by covering the outer periphery of a core material made of an acrylic fiber with a polymer film and swells by absorbing water.

<D> Customer soil (FIG. 4) Finally, the soil 6 is sprayed until the net 6, the support frame 2 and the horizontal net 1 are hidden, and the construction is completed. As a vegetation method, a method in which seeds and fertilizers are mixed in the soil 9 is sprayed, or a plant is planted after the construction of the soil 9 is completed. The weight of the soil 9 acting on the horizontal net 1 is supported by the support frame 2 via the fixing pins 3.

<D> At the time of draining The rainfall that has penetrated into the soil 9 in FIG. 4 is absorbed by the water supply rope 8. Furthermore, the rainwater that has penetrated to the deep part of the soil 9 permeates 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, since the water-permeable mat 5 is interposed between the lining layer 4 and the soil 9, a drainage channel is formed inside the water-permeable mat 5 to effectively flow down the soil 9 as described above. It can be prevented.

<F> During sunshine Since the soil 9 is formed on the surface of the impermeable lining layer 4, the water in the soil 9 will be depleted if 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, water is supplied from the water-permeable mat 5 to the soil 9, so that a suitable growth environment for plants can be maintained even if the sunshine continues for a long time.

[0020]

[Other Examples]

 Although the above-mentioned embodiment has been described on the premise that the ground layer is covered with the lining layer 4 such as sprayed mortar or sprayed concrete, it may be directly applied to the ground without the lining layer 4.

[0021]

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

<a> Since the method frame device can be assembled by a simple operation of restraining the midway of the horizontal net with a lightweight support frame and fixing the support frame with pins, the method can be easily installed even on a steep slope. You can In particular, it is possible to target the existing sprayed mortar and lining layer covered with sprayed concrete, which had been difficult to green up to now.

<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 water supply rope on the surface of the lining layer, not only the water retention performance of the soil can be improved, but also water can be supplied into the soil so that a good vegetation environment can be maintained for a long period of time. Can last.

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