Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a revegetation lawn structure for revegetation of a slope by a local surrounding plant.

[0002]

[Prior art]

 As a method of reinforcing slopes such as roads and lands, after laying a mesh such as a wire mesh on the slopes, reinforcing bars are arranged in a grid on this mesh, and then the bars are laid in a grid. There is a construction method in which a mortar or the like is sprayed so as to fill the gap, and a grid-like method frame with steel bars is constructed on the slope.

[0003] After the construction of this legal framework, a vegetative matrix is sprayed between the legal frameworks to sow plant seeds or plant tree seedlings, or a vegetative matrix containing plant seeds is blended with the legal framework. Spraying in between can green the slope.

According to this construction method, since the frame is lattice-shaped and continuous vertically and horizontally, it is possible to develop a strong resistance to peeling of the surface layer of the slope, and the conventional cast-in-place method The workability and economy are superior to the construction method.

[0005]

[Problems to be solved by the invention]

 However, in the above-mentioned construction method, there is a problem that the plant is different from the surrounding vegetation, so the familiarity with the surrounding landscape is poor, and a sense of incongruity remains forever. The formation of vegetation and the transition of vegetation were difficult to progress even after a long period of time, and there was a problem in disaster prevention.

[0006] The present invention has been made in view of such circumstances, and its purpose is to relatively quickly transition the vegetation (reconstruction of vegetation) by local plants without disturbing the ecosystem. To provide a greening framework that can be used.

[0007]

[Means for Solving the Problems]

 In other words, the greening method frame structure according to the present invention is a method using a wire arranged at least vertically or horizontally parallel to the slope directly or via a mesh, and a mortar or concrete embossed so as to embed the wire. It is characterized in that it consists of a frame and a local topsoil in which the surrounding plant seeds laid between the law frames are latent (claim 1).

[0008] According to the above-mentioned tree planting method framework structure, by cultivating and growing latent seeds by cultivating and growing potential seeds on the local topsoil where the local surrounding plants are hidden between the legal frameworks, the vegetation by the local plants is relatively early. Transitions can be made.

[0009] That is, the slopes can prevent the surface layer from collapsing on the slopes, and can prevent the surface erosion without damaging the surrounding landscape and ecosystem by the greening by local vegetation.

[0010]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 and Fig. 2 show the initial state of greening by introducing local vegetation to the slope N. When constructing this greening frame structure, firstly the plants around the slope N to be greened are to be planted. Prepare the local topsoil 1 with potential seeds.

[0011] In the collection the local overburden 1, as shown in FIG. 3, for example, small bushes or Kaya, eliminates undergrowth such bamboo by weeding, and A ₀₀ layer litter is accumulated, planted decomposition and a ₀ layer deciduous humus is accumulated, and a ₁ layer humus and soil mixed, directed to the a ₂ layers of missing nutrients, construed by using these, or the like, for example Kountsume 2, which Can be collected as the potential local topsoil 1 of the surrounding plant seeds.

[0012] The sampling area of the local topsoil 1 is not limited to the area around the slope N to be greened. For example, a sampling area for a new town development area or a road construction area for large-scale land reclamation is also collected. It is targeted. If necessary, soil improvement materials such as peat moss, bark compost, and bentonite, water retention materials such as perlite, vermiculite, and high-grade aquatic polymer, as well as organic compost, chemical fertilizers, and plant fibers are used as the local topsoil. They are mixed appropriately.

On the other hand, returning to FIG. 1, a net-like body 3 such as a rhombus or a tortoiseshell is laid on a slope N to be greened, and auxiliary anchors 4 are driven into the slope N at appropriate intervals. Then, the mesh member 3 is fixed to the slope N.

Next, wires 5 made of a reinforcing steel bar (other than, for example, a wire rope or the like) are arranged on the mesh body 3 at least vertically or horizontally in parallel with each other, and preferably arranged in a lattice as shown in the figure. Then, a frame 6 for forming a legal frame is installed in the longitudinal direction of the wire 5, and the wire 5 is lifted and held by the frame 6.

The frame 6 for forming a legal frame has a height of about 15 to 20 cm, a width of about 30 to 35 cm, and a length of about 30 to 60 cm. It has a combination structure.

Specifically, as shown in FIG. 2, a pair of semicircular frame members 7, 7, and a wire rod holding member 9 extending over connecting members 8, 8 integrating these frame members 7, 7. , 9.

Therefore, after the frame 6 is installed so as to straddle the wire 5, the wire 5 is lifted to the wire holding members 9, 9 and bound to the wire holding members 9, 9 by a number wire b or the like. As a result, the wire 5 is held at the predetermined height position on the slope N.

Returning to FIG. 1, the curing sheet 10 is arranged on the three nets of this area so that the area surrounded by the grid-shaped wire 5 becomes a vegetation area, and the mortar or concrete ( (Hereinafter referred to as mortar.) 11 is used such that the frame 6 for forming the legal frame is used as a guide of the spray width and the spray height, and the grid-shaped wire 5 and the frame 6 for forming the legal frame are embedded. To form a grid-shaped normal frame 12 on the slope N by raising the mortar 11.

Then, after the mortar 11 has been cured, the curing sheet 10 is removed, and the local topsoil 1 that has potential plant seeds in the vegetation area is covered with the soil, thereby completing the construction of the greening method frame structure. is there.

In some cases, soil improvement material, water retention material, organic compost, fertilizer, plant fiber, and the like may be appropriately mixed in the local topsoil 1. Topsoil 1 mixes 10-20%.

According to the above-mentioned tree planting method frame structure, by cultivating and growing the seeds by cultivating and growing the seeds by cultivating and growing the seeds in the local topsoil 1 where the seeds of the local surrounding plants are latent. Falls on the soil created by pioneering trees, etc., and germinates and grows again to form a forest on the slope N. As a whole, the plants on the slope N The transition of the landscape and the conservation of the landscape will be achieved early.

In the above embodiment, soil improvement material, water retention material, organic compost, chemical fertilizer, plant fiber, and the like are appropriately mixed into the local topsoil 1, but the surrounding plant seeds latent in the local topsoil 1 are germinated and grown. If it is desired to stabilize the topsoil 1 at the earliest stage, a small amount of exotic herbaceous seeds that grow quickly can be added to the topsoil 1. In addition, the cross section of the legal frame may be formed in a rectangular shape using a mold, and in this case, a higher strength can be obtained as compared with the above-described legal frame whose cross section is a broken circle.

The above-mentioned wire 5 is arranged in parallel in the vertical direction, and a mortar 11 is sprayed so as to embed the wire 5, and a straight normal frame 12 is formed on the slope N by raising the mortar 11. Although the wire 5 may be formed, the wire 5 may be arranged in parallel in the lateral direction, and particularly preferably, since the resistance to the collapse of the slope N is increased, as described in the embodiment, That is, the wires 5 are arranged in a grid, and the normal frame 12 is also formed in a grid.
