Description

[Detailed description of the invention] A0 Purpose of the invention A. Industrial application field Suitable for construction projects such as roads, bridges, tunnels, covered roads, retaining walls, etc., and urban environment improvement projects such as streets, power transmission lines, advertising towers, etc. The aim is to provide a greening method using vines.

1. Conventional technology and problems ■ Recently, with the increase in development activities, the destruction of nature has become significant, and there is a strong demand for its restoration. The contents are not limited to just restoration, but have very strong landscape demands.
We are also forced to develop greening technology that incorporates landscape elements. In terms of conventional disaster prevention technology, there is something to be said for greening technology that mainly relies on metals, and there has been remarkable progress in one-sided treatment.However, mortar spraying is used to prevent the collapse of rock surfaces and rock slopes where it is difficult to grow vegetation. Trees should be maintained at the entrances and exits of tunnels, concrete and steel pillars for covered roads installed for disaster prevention, concrete retaining walls for earth retention, and utility poles on roads. Despite efforts to maintain the urban landscape, no landscaping measures have been taken to replace exposed concrete and steel frames in various parts of the roads that weave through green valleys and mountains. . There are some areas where color treatment has been carried out by mixing concrete aggregates and pigments, but as the colors fade over time, the situation has arisen that actually impairs the landscape.

U. Traditionally, greening in the fields of use listed in the previous section has been extremely difficult. - Greening of slopes has been done through grasses and vegetation, and various materials and construction methods have been developed for this purpose. Although this has been achieved with considerable success, this is based on the premise that the slope angle is within an angle that can maintain the vegetation base. Attach it to the rock surface and create a soil outlet t-
Protect and grow herbaceous plants. In addition, steps are installed on the slope, or vegetation holes are made, and woody and herbaceous plants are planted using added soil. The central issue of the technology was whether or not it would be possible to prevent the flow from occurring. However, since it is nearly impossible to maintain the vegetation base on steep slopes and rock slopes, should wire netting and cement mortar spraying be carried out on steep rock slopes that are at risk of weathering to prevent flaking and sliding?

Alternatively, the main construction method is to prevent traffic accidents caused by flying stones and falling rocks by using a rockfall protection wire mesh, and it has not reached the level of construction technology used for landscape measures. In addition, in the other fields of use mentioned in the previous section, methods such as painting or coloring concrete by mixing it entirely with pigments were used, and there were hardly any noticeable methods. Therefore, does the structure have exposed concrete surfaces?

It is nothing more than a painted steel frame or galvanized steel sheet surface. It is no exaggeration to say that it has no aesthetic or landscape significance.

The fundamental problem is that maintenance of the vegetation base layer on these steep slopes and rock slopes is either impossible or close to impossible. Therefore, the inability to supply not only moisture, which is a condition for the growth of vegetation, but also nutrition, makes it impossible for vegetation to take root, causing problems in terms of landscape and environmental destruction.

In addition, in other structures, concrete walls and exposed steel surfaces that do not suit the landscape must be painted exclusively industrially, or Watanabe materials are used, which can cause fading, rusting, or peeling over time, resulting in an ugly appearance. A situation arises.

B0 Structure of the Invention A1 Means for Solving the Problems The invention of the present application uses corrosion-resistant wire mesh or synthetic resin mesh to easily entangle concrete walls, rock walls, concrete pillars, steel poles, utility poles, and other facilities targeted for greening. This is a greening method using vine plants, in which pots for storing fertilized soil are installed at the base of the facility to be greened, and vine plants are propagated in the pots.

Example: The basic idea of the present invention is to apply temporary measures such as adding soil to the surface of the structure described in the previous section, which would otherwise be impossible or impossible, or applying paint that deteriorates significantly over time. denying the implementation of the policy, stably and permanently, and
Choose a method that is easy to implement rather than impossible. It is inevitable that soil on a slope will slide down the slope due to gravity or the effects of rain, wind, earthquakes, etc., or it will lose its stability due to collapse, frost heave, creep of snow, etc., and will be deposited down the slope. Also, covering walls and pillars that stand vertically with plants is simply done by utilizing the small amount of money available and by the climbing power of their suckers. But-
Even in such cases, if fertilization is not carried out after planting, the plants will die or will not be able to achieve their full coverage ability. In particular, it must be considered that the locations where the present invention is practiced are under extremely severe conditions.

According to the present invention, in order to cover the above-mentioned structures and sites with plants, the soil, which is the basis for plant growth, is created in the most stable, horizontal, and place where there is no risk of washing away. That is, we artificially create optimal soil conditions for planted plants at the bottom of the slope or at the foot of a structure, and use pots that are easy to maintain and maintain stable growth conditions so that they do not wash away. It is thought that the climate and growth conditions of the location are optimal for plants to be planted on this base. We select the type of vine and install netting aids to best utilize its characteristic climbing organs such as tendrils, suckers, and aerial roots. The surface of the structure is covered with green stems.

(1) Greening of utility poles Landscape issues in cities and blocks originate from the form of formation and development of the city or block and subsequent urban planning, but the main content is architecture, which is the main component of the landscape. In the case of Japan, since the Meiji period, the development pattern has been one that prioritizes industrial economy, and the scenic significance of cities and blocks has been considered secondary, and has rarely been treated as a major issue. However, in recent years, with the emergence of environmental issues, these landscape issues have also come to be taken up as important themes, and in addition to the development of distinctive parks and green areas, a certain amount of budget has been allocated to preserving historic townscapes, improving streets, and maintaining tree-lined areas. Measures are now being taken, and local residents are starting to take a strong interest in the matter.

However, there is a problem with the disposal of the power poles that stand in the way of the streetscape. Utility poles, which have been a symbol of civilization since the Meiji era, are becoming a problem not only from a traffic perspective, but also from a scenic standpoint. In some cases, a common ditch is built and the waste is buried underground.

If it were to be implemented on a large scale, it would require a huge amount of money, so there is no hope that it would be implemented quickly.

Therefore, in the present invention, the idea was to green the telephone poles and use them as a facility for maintaining the landscape in the same way as the rows of trees. That is, as shown in FIG. 1, the electric pole 1 is placed on the ground. The mounting bracket should be designed so that it can be fixed to the utility pole body so that the above-mentioned auxiliary tool does not come off or fall off the utility pole, and the wrapping auxiliary tool maintains a distance of approximately 5 crrL from the surface of the utility pole over the entire circumference. Manufactured as follows. Since utility poles are manufactured to several different standards, this can easily be determined by their dimensions. The distance between the surface of the 5cIrL utility pole and the above-mentioned auxiliary tool is such that the vines 5 planted in the planting bots 4 on the underground part of the utility pole are wrapped around each other by their curls, stems, suckers, and aerial roots. This is to make it easier to climb up. The underground part of the telephone pole is the 12th
A pot 4 for planting a vine plant (see Figure 14) is dug in the ground around the telephone pole and buried, and then filled with a medium 6 mixed with organic matter and fertilizer necessary for growth. Then, vine plant seedlings 7 are planted in the soil. In this example, two concrete power poles in our factory have a height of 8.
m.

A cylindrical split wire mesh with a frame of 50 cIrL in diameter and 5 cIrL in mesh size was fixed, and the base of the utility pole was excavated. Pots with wire mesh filters filled with soil were buried close to the surface of the ground. Two-year-old "Parthenocissus" seedlings were placed inside each one. I planted 4 plants and observed their growth and covering condition in the first year (May to October).
During the growing season, K had a growth height of 7 m, a coverage rate of about 90%, and a coverage rate of 62 inches (1980), and a 6-year In June, it had grown near Ion, so we cut off the tip and pinned it in place to prevent it from interfering with the railroad tracks. Judging from this, it appears that the intended purpose was fully achieved. Note that the auxiliary tool 2 and the bot 4 are made of corrosion-resistant wire mesh or synthetic resin mesh.

(2) Greening of covered road supports Road covered roads are one of the types of construction that have been used frequently in recent years, and are a facility to ensure the safety of roads that traverse steep summer areas where falling rocks and avalanches are likely to occur. They are usually built with a sturdy steel structure or reinforced concrete structure.

These roads generally pass through mountains and valleys, coastal erosion areas, and wind tunnel areas, and are scenic spots with great views. However, in the above-mentioned structure, the retaining walls on the mountain side are hidden by a cover and cannot be seen, but the pillars on the valley side are either exposed gray-white concrete or coated with anti-rust paint on the steel frame, so there is no consideration given to the landscape. It seems that there is no such person. Although there has been a strong desire to improve the landscape of these facilities, no appropriate measures have been taken. It might be more accurate to say that there was no suitable method. The present invention aims to cover the surfaces of these structures with greenery using ``vine plants'' to create landscapes that do not look out of place with natural vegetation, but rather resemble nature itself. FIG. 3 shows an example of this. The foundation legs of the prismatic concrete pillars or H-shaped steel pillars 8 installed on the Shododani side were excavated, and a wire mesh bot 4 with a filter was filled with culture medium ±6 as shown in Figure 13. Seedlings 7 of vine plants ``Yamabudo'' and ``Matatabi'' were planted in the soil using Miki's embedding technique, and on the other hand, on the side of the support, a full-mesh seedling as shown in Figure 10 was planted. In order to be able to fix the above-mentioned auxiliary tool 2 at approximately one-half of the valley side of the support surface, the mounting bracket 6 is attached to the H-shaped steel support with a size that can withstand the constant weight of the auxiliary tool and plant growth. Weld the required number of nails at , - points, and drive concrete nails at certain points for concrete columns.

Weld a mounting bracket as described above to this nail.

After that, firmly fix the above-mentioned auxiliary tools to the metal fittings, and wait for the vines directly below to grow and become entangled with their climbing organs such as tendrils, suckers, and aerial roots. The buried vine plant of the above example finished covering one side after about 6 years, and a part of it had extended toward the path, so it was cut off. These vines shed their leaves in winter.

It turns green in the spring, turns red in the fall, produces small flowers during the flowering season, and the fruit is only processed as food (and fits perfectly into the surrounding landscape).

Note that the bot 4 is embedded in contact with the valley side foundation footing 8A. 10 indicates a road inner groove.

(3) Mortar spraying is used for greening slopes when widening or improving existing roads, and
Slope cut marks are extremely unstable, such as the construction of ravine roads for dam construction or the remains of raw stone collection sites for aggregate collection, and the surfaces are extremely vulnerable to deterioration due to weathering and freezing. easy to become.

Construction of rockfall protection nets is often carried out to prevent rockfalls and small collapses, but it is extremely difficult to install rockfall protection nets on steep slopes, sandstone, mudstone, or gravel-like rocks that appear to be stable. Because it has the property of accelerating weathering, it is sometimes more effective to spray cement mortar than to prevent damage with a rock fall protection net, and this can often be seen at construction sites. Their thickness is 10C
In many cases, wire mesh is often used to prevent peeling. These mortar sprays on the side of the road often cover a large area of the slope, and are grayish-white in color, seriously damaging the surrounding landscape. Book.

The purpose of this invention is to use mortar spraying to green the slope and completely restore its landscape. Figure 6 shows an example of this practice.The sandstone walls exposed on the steep slopes carved out of Road-11411K are easily weathered and crumbled, so the entire slope was covered with lath wire mesh and cement mortar was sprayed. As the area is surrounded by many trees and has a beautiful valley, landscaping and greening was requested, but as it was impossible to place soil on the slope, it was not possible to carry out greening with plants. According to the present invention, the foot of the slope is excavated, the pots shown in Fig. 14 are buried vertically along the entire length, and the soil is filled with soil mixed with organic fertilizer, vegetable fiber, peat moss, etc., and vines are planted in it. Cut the branches of the darutata into 3 or 4 nodes.

As shown in Figure 7, it is caused by budding growth.

Due to the unique suction cups of ivy, the mortar spray sticks to the wall surface and began to cover the entire wall of a building gracefully, but one condition is much more severe than in construction, and in cases of heavy rainfall. Being hit by falling water flowing down the wall like a waterfall,
When it snows, the snow creep on the slope causes the suction cups attached to the wall to be torn off, preventing the plants from climbing to quickly respond to growth.
It was found that the covering power could not be fully exerted.

It has been found that heavy rain can cause problems such as areas where the pot soil is washed away by running sewage, so we installed a concrete trough between one leg and the pot at a distance of about 50 cIrL from all legs of the pot. to ensure rapid drainage of wastewater outside the site, and
A thick filter made of tough cloth is lined inside the pot to prevent the flow of particles, humus, and fertilizers, and a wire mesh is stretched over the entire slope, and this is fixed to the slope by driving strong anchors. At the same time, it increases the frictional resistance against snow creep and protects the suction cup.

When the entanglement of aerial roots and tendrils was made easier, the coverage increased rapidly and the greening of the slope was almost successful. 1
1. For mortar spraying, a flat plate-like auxiliary device made of corrosion-resistant wire mesh is stretched over the entire surface of the slope to assist the curling and climbing of single plants and to prevent them from falling off. 12 is an anchor bolt for fixing a flat plate-shaped auxiliary tool to a slope; 1

Reference numeral 18 indicates a drainage ditch for rapidly draining runoff from rain or snow melting to the outside of the slope so as not to harm the plants. Note that FIGS. 8 and 9 show the auxiliary tool 2 used for circular supports, and FIGS. 10 and 11 show the auxiliary tool 2 used for square supports. Then, when installing it, make sure to surround the pillar.

The mating end is then tightened with a clip to form a cylindrical shape and is attached to the support so as to maintain a constant distance from the support. 2

is the frame line of the joint end, +8% aluminum coated steel wire -20 is the horizontal bone line and aluminum coated steel wire + 2D is the vertical bone line and is aluminum coated steel wire.

Further, the pot 4 is constructed of a wire mesh woven to have a suitable mesh and made of corrosion-resistant aluminum-coated steel wire.

4A is an outer frame line that uses aluminum-coated steel wire of approximately f6 or higher. 4B is a backbone wire, and an aluminum-covered wire of an appropriate standard is used to avoid large deformations. 4C is a filter made of non-woven fabric with a thickness of 10 to 201% to prevent the cultivation soil from flowing away. Furthermore, various organic substances, humus, vegetable fibers for preventing the flow of water, etc. are mixed into the culture medium ±6 as required. The shape of the pot may be configured in the form of a circuit break, or may be configured in an L-shape for retaining walls or short rock slopes.

Effects of the C1 invention A. We selected the most suitable vines for the topography and weather conditions of the site, and created auxiliary tools using wire mesh made of corrosion-resistant aluminized steel wire or synthetic resin mesh to fully demonstrate their climbing properties. It is installed and fixed to the structure that is to be greened, and a pot lined with a thick filter is buried under the foot of the structure that requires greening so that vines can grow sufficiently and quickly. Fill with soil mixed with other lipids necessary for life, and plant seedlings or buried branches in the soil to prevent the soil from flowing out and encourage the growth of a single plant, even against abnormal flow of sewage such as rain or snowmelt water. Due to its strong growth and climbing ability, upright structures and steeply sloping mortar spraying, which were previously considered impossible, have made it possible to naturally green the slopes with plants, and also to improve the seasonal effects such as green leaves, flowering, and autumn leaves. It can respond to changes and greatly contribute to the landscape of the surrounding area.

B. Wire meshes used for auxiliary tools are made of highly corrosion-resistant aluminized steel wire and synthetic resin, so they are resistant to corrosion and have semi-permanent durability. The planted vines are 2.
Simple fertilization once every three years and trimming of excessive vines will maintain a permanent covering power and contribute to the landscape.

Even in the unlikely event that a part of the tree is damaged or damaged, it is very easy to replant or replace it, making it a permanent construction method that is highly economical.

The work is easy, the auxiliary tools are factory-produced, so standard quality can be ensured, and the vines are uniformly grown by gardeners, making it possible to supply them in large quantities.
The construction period is shortened and temporary scaffolding is not required, making it economical.
