Description

[Detailed description of the invention] (Industrial application field) Concrete spraying on bare concrete retaining walls where greenery has been lost, walls of structures such as elevated sections of railways and roads, buildings, tunnel entrances and exits, utility poles, etc., or on mountain surfaces. This invention relates to a wall greening method that can effectively and rationally green walls, create a lush green landscape that harmonizes with the environmental landscape, and can also contribute to traffic safety measures.

(Prior art) Restoration of the green landscape lost due to the deterioration of modern concrete structures, especially concrete walls, is an urgent social need, but conventional methods for greening these concrete walls include:
For example, in the case of greening a retaining wall, the soil around the side of the retaining wall is dug up and ivy is simply planted in it to make it grow on the wall. The growth rate is only about a few tens of centimeters a year, and it only grows horizontally.
Or, because it only crawls on the floor and does not grow vertically,
The desired greening could not be achieved sufficiently. ■Also, conventionally, the method of greening the concrete sprayed surface of a mountain is to partially drill holes in the concrete sprayed surface to create a hole (exposed part of the ground), and use this as a seedbed to plant seeds and seedlings. However, with this method, it is impossible for the roots to take root because the soil at the root does not receive enough sunlight and water, and the soil has insufficient air permeability and water retention. It was not possible to achieve sufficient greening of the sprayed surface, which in fact weakened the concrete sprayed surface, leading to the risk of an accident due to the mountain sails collapsing.

Recently, models of ground cover plants made of synthetic resin products such as plastics have been pasted on the walls of retaining walls, buildings, etc., but these are just decorations and do not represent true greening. Not only are they of no use, they also get damaged and become extremely unsightly as time passes.

■At present, no effective and appropriate method for greening the walls of structures such as concrete has yet to be disclosed.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned drawbacks of the conventional method when greening walls such as conch IJ-1 retaining walls, and allows the roots of ivy and other species to take root in the ground for greening. By making it easier, the vines grow and flourish in the vertical direction along the wall surface (-By making it easier, the greening of the concrete wall surface of structures such as the front wall, or the concrete sprayed surface of the mountain surface, etc. can be effectively done as desired, and the weathering of the wall surface can be prevented. The overall purpose of this study is to obtain a method for wall greening that is effective for harmonizing with the environmental landscape by restoring greenery, neutralizing polluted air, and also for traffic safety measures.

(Means for solving the problem) Therefore, after carrying out various trials, the applicant has decided to green the concrete retaining wall (A) etc. (1).
Artificial (3) soil (2) mixed with any amount of slow-release fertilizer, water retention agent, plant growth agent, etc. in a well-balanced manner is placed at any number of locations closest to the outside of the lower end of the concrete (1) sprayed surface). Any number of direct boxes accommodated. set up,
Float the growth support net (4) on the entire surface of the wall and attach the anchor (
5), so as to raise the seedlings at appropriate intervals above the core wall surface. We have developed a wall greening method in which the vines are entwined with the above-mentioned growth support net and grown vertically, allowing them to flourish over the entire surface of the wall, and have solved the above problems. Ta.

Effect) The present invention provides the artificial soil @ (2
) is arranged, and the growth support net (4) is suspended and suspended from the wall surface (1) with an appropriate gap (floating part) (6) separated from the wall surface using anchors (5) and stretched on the wall surface. It is characterized by the following points, and therefore has the following effects.

■ The seedling box contains artificial soil mixed with a well-balanced mixture of slow-release fertilizers, water retention agents, etc. that are effective for the survival and growth of ground cover plants such as ivy, so the roots of ivy and other ground cover plants are absorbed into the soil. Sufficient rooting and natural growth■ The growth support net (4) stretched over the entire wall surface serves to help the vines of groundwater plants such as ivy to entangle with it and grow vertically upward.

In addition, this growth support net (4) is appropriately suspended from the wall surface and fixed to the wall surface by a floating anchor (5) with a spacer (5b) and a floating wanoshi six (5C) attached to the anchor (5a). In other words, there are floating parts (voids, gaps) (6) at appropriate intervals between the wall surface and the growth support net.
By providing this, it is easy for groundwater such as ivy to get entangled with the growth support net, and there is an effect of promoting the growth and flourishing so as to cover the entire wall surface.

The direction can be controlled in the morning direction, faster growth and flourishing can be achieved, and the wall surface can be covered as desired due to the rich greenery.The lost greenery can be restored and a green concrete structure can be created. This has an effective effect on harmony with the environment, harmony with the landscape, and traffic safety.

(Example) Next, an example of the present invention will be described based on the accompanying drawings. However, the present invention is not limited to this.

The wall greening method according to the present invention includes, for example, applying an arbitrary amount of slow-release fertilizer, water retention agent, plant growth agent, etc. to any number of nearest locations outside the lower end of the wall (1) of the concrete navel (A). An arbitrary number of seedling boxes (3) containing artificial soil (2) mixed with the appropriate amount of seedlings are installed, and growth support nets 71- (4) are floated on the entire wall surface (1) of the retaining wall (A) and anchors (5) are placed there.
, it is stretched and fixed with an appropriate gap (floating part) (6) separated from the wall surface. Then, seedlings of ground cover plant 1, for example, α (7), are planted in the artificial soil (2) in the seedling box, and their roots are sufficiently established in the soil (2) to grow their vines. The vines are made to climb up on the growth support net and are entwined with each other to grow and flourish, so that the entire wall surface (1) of the retaining wall is covered with the greenery of the vines.

The seedling box (3) has a shape that matches the structure of the retaining wall (A), and its constituent material is robust and non-corrosive to withstand long-term use, with no washer (5C) for seedling growth.
), and these anchors allow the growth-assisting net (4) to form an appropriate gap (
Floating part) (approximately 51 cm) is placed on the retaining wall.

This is a stopper to prevent it from rising upward and covering anything other than the wall surface (1).

(Effects of the Invention) The present invention has the above-mentioned effects, and by rationally utilizing the characteristics of ground cover plants, the wall surfaces of structures such as concrete IJ retaining walls can be rapidly and sufficiently revegetated. By allowing it to grow and flourish over a long period of time, it is possible to provide a lush green landscape that harmonizes with the surrounding environment, prevent retaining walls from weathering, and neutralize polluted air to protect people and livestock. It can be said to be a rational and highly effective wall greening method that can contribute to society by having health effects, providing peace of mind to the eyes of passersby, and contributing to traffic safety measures.
