Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a greening member that is most suitable for planting on a slope, and more particularly to a greening member that enables planting on a soil slope where it is difficult for trees to settle and shortens the construction time required for the planting.
[0002]
[Prior art]
For example, when a mountain is cut for quarrying or mining, a slope G is formed after the mountain M is cut as shown in FIG. Naturally, there are no trees on this slope G, so the landscape was remarkably damaged, and only that portion lacked water retention, causing disasters such as landslides. Therefore, it is desired to plant trees on such slopes and plant them, and it has been known to plant trees as means for this purpose.
[0003]
[Problems to be solved by the invention]
However, since this type of slope is formed after quarrying and mining, it is natural that the soil is stone or rock, and it was extremely difficult to plant trees there.
[0004]
Of course, a certain kind of tree represented by pine can be grounded even if the soil quality is stone or rock, so that it can overcome the roots and root. However, it takes many years to reach this state, and until then, trees must be established on the slope and grow. In this case, in the prior art, the soil for growing trees was provided on the slope, but unlike the flat land, applying soil on the slope requires a lot of labor, and the corner soil is applied. However, there was a risk of spilling out with rainwater.
[0005]
In addition, if the soil layer is thin, the tree will rise with respect to the hard slope as the root grows, and the root will not enter the slope and land.
[0006]
Furthermore, when the slope is steep (for example, it may be close to 75 °), it is extremely dangerous for a worker to climb the slope to plant trees, and a special scaffold is also required. There was a problem in both.
[0007]
[Means for Solving the Problems]
The present invention was created for the purpose of providing a greening member that enables the greening of a slope that has solved the problems of the prior art as described above. That is, the greening member of the present invention is made of a material that can penetrate the roots of the tree, and is fixed to the top of the sandbag by a sandbag in which a plurality of compartments provided with windows communicating with the outside are continuous in the full length direction. It is made up of a grid-like frame body, and the soil is housed in the sandbag and trees are planted from each window, the frame body is rigid and the grid has a size that allows the stem or trunk of the tree to pass through. It is characterized by. Incidentally, Japanese Patent Laid-Open No. 10-195878 exists as a document disclosing a known invention related to the present invention, and planting on a slope using the greening member of the present invention is a use of the present invention.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, specific examples of the greening member and the method of using the same according to the present invention will be described with reference to the accompanying drawings. FIG.1 and FIG.2 is a figure which shows the greening member P of this invention. This greening member P is composed of a sandbag 1 and a frame body 6.
[0009]
The sandbag 1 is configured by sequentially connecting a plurality of compartments 2 for accommodating the soil therein in the full length direction of the sandbag. The material constituting the sandbag 1 must be at least flexible and strong enough to break through the root of the tree T. Here, for example, polyester, nylon, polyethylene, polypropylene, polyester span A non-woven sheet made of bonds or the like is assumed. Note that the sandbag 1 is illustrated here as a completely closed bag-like shape. However, the sandbag 1 may not necessarily be completely closed as long as the soil can be accommodated, but may be a bag-like shape whose end can be opened and closed. Of course.
[0010]
Reference numeral 3 in the figure denotes a window provided in the compartment, and in this embodiment, it is configured as a slit along the entire length of the sandbag 1. The windows 3 are provided corresponding to the number and interval of the trees T arranged in each of the compartments 2. However, if necessary, the compartments 2 may be further divided into one window or a plurality of windows. Needless to say, the partition wall for this is not shown.
[0011]
A frame 6 is superposed and fixed on the upper surface of the sandbag 1. The frame 6 has a lattice size that allows the stem or stem of the tree T planted in the sandbag 1 to pass through, and has a rigidity that does not bend even if some bending due to the weight of the sandbag is allowed. Is a requirement. In this embodiment, the frame body 6 is formed by joining metal wires in a lattice shape. The frame 6 is preferably of a size that covers the upper surface of the sandbag 1, and a plurality of sandbags may be fixed to one frame body. Here, the sandbags 1. 1 shows an example in which one frame body 6 is superposed and fixed to form one greening member P. As a means for fixing the sandbag 1 and the frame body 6, a means for directly connecting the outer frame portion of the frame body to a blank portion (not shown) provided around the end of the sandbag or around the sandbag by a string or a band (not shown). Of course, other means may be used.
[0012]
The soil 4 is accommodated in the sandbag 1 of the above greening member P, and the tree T is planted. The soil 4 may be poured from the window 3 into each compartment 2 of the sandbag 1 or, if the end of the sandbag can be opened and closed, from there into each compartment. Usually, when cultivating a plant in a container, it is common knowledge that the soil should be organic and include nutrients such as fertilizer. However, in the case of the greening member of this invention, the soil should be inorganic and fertilizer. It is desirable not to include such nutrients. The reason will be described later.
[0013]
The tree T is planted from each window 3 of each compartment 2 of the sandbag 1. The planting of the tree T may be before or after the soil 4 is accommodated, and these operations may be before or after the frame body 6 is fixed to the sandbag 1 by polymerization. Of course.
[0014]
The above greening members are used by being placed on a slope where greening is desired. That is, the greening members P are prepared in the number of areas for which the slope G is desired to be greened, and are sequentially arranged at predetermined locations on the slope G (see FIG. 6). Hereinafter, the case where a slope is a stone or a rock is taken as an example, and the tree-planting method using the greening member of this invention is demonstrated based on FIG. 3 thru | or FIG.
[0015]
The greening member P arranged on the slope G is fixed to the slope, but here, an anchor is employed as a fixing means. As shown in FIG. 3, first, anchors 7 (assumed to be made of metal having a length of 2 to 3 m) are buried by driving or the like at a required interval on the slope G where trees are planted. Next, as shown in FIGS. 3 and 4, the greening member P that has been implanted is lifted by a crane or the like, and is placed on the slope G with the trunk portion of the tree exposed from each window. Then, the greening member P arranged on the slope G has the frame 6 fixed to the anchor 7 on the slope (see FIG. 5). Here, the frame 6 is fixed to the anchor 7 protruding from the slope G by a wire or the like, but it is needless to say that the fixing method to the slope is not limited to this.
[0016]
On the other hand, in this usage example, the soil 10 is filled between the sandbag 1 and the slope G in order to improve the netting of the tree T and to adjust the sandbag 1 to the unevenness of the surface of the slope G. Yes. As shown in FIG. 3, the filling of the soil 10 is performed by spraying on the slope G from the back surface direction of the sandbag 1 by the hopper 20 or the like when the greening member P is lifted.
[0017]
The tree T having completed the above operations is first grown using the soil 4 in the sandbag 1 of the greening member P as a soil floor, and then the extended roots grow through the sandbag 1 and grow on the soil 10, and reach the slope G. Start to root. And finally, the tree T will completely land on the slope G (state of FIG. 7). In this case, since the soil 4 inside the sandbag 1 does not contain nutrients, the root part of the tree T grows fast in search of nutrients, while the trunk, stems, leaves, etc. on the ground part have little nutrients. As a result, it is possible to prevent a situation where the trunk, stem, leaves, etc. grow too much and fall off the greening member P due to its weight before the tree T reaches the slope G. . Needless to say, in the above-described stage, the stem or the trunk T1 extending on the ground of the tree T penetrates the lattice of the frame body 6.
[0018]
【The invention's effect】
The present invention has the following specific effects.
(1) Trees can be planted on the ground. After planting, tree planting is completed simply by lifting the greening member, placing it on the slope, and fixing it. It is not necessary and can be planted easily regardless of its slope.
(2) Similarly, even if the slope soil is stone or rock, it can be planted easily.
(3) Since the tree is fixed to the sandbag of the greening member fixed on the slope, there is no possibility of the tree flowing out due to rain water or the like, and reliable tree planting is realized.
(4) Trees are first grounded using the sandbag of the greening member as the ground, and the root reaches the slope in the next stage. Because it is firmly fixed to the surface and has its own weight, there is a risk that the tree will rise with respect to the hard slope as the root grows, and it will not enter the slope and land And reliable tree planting is realized.
{Circle around (5)} According to the present invention, a slope caused by quarrying or mining, which has been extremely difficult to plant trees in the past, can be easily greened, contributing to landscape protection and flood control.
