Abstract

PURPOSE:To protect a slope as well as grow greens by a method in which plural seed cylinders are set on the slope of the ground, and concrete or cement mortar is sprayed onto the outside of the seed cylinders. CONSTITUTION:After the slope of the ground 1 is graded, a metal netting 2 is closely laid on the slope and fixed with anchors 3. Drain pipes 4 and seed cylinders 5 are set at a given interval vertically and horizontally. Cement concrete or mortar 6 is then sprayed onto the outsides of the pipes 4 and the cylinders 5 set on the slope to an extent that the tip portions of the pipes 4 and the cylinders 5 are not buried. The cylinders 5 absorb water, paper bags are broken, seeds (d) are allowed to germinate, and greens-planting work is thus attained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slope protection method, and more particularly, to a method for protecting the slope of a mountain by covering it with vegetation while cultivating it.

It is not good for the landscape if the slope of the ground is left bare.
It is desirable to carry out vegetation greening at the same time as protection. However, in the conventional construction method of spraying and covering the slope with concrete or mortar, the protection of the slope was prioritized and no consideration was given to greening, leaving the slope in a bland environment. However, there were drawbacks such as poor scenery.

The object of the present invention is to eliminate the drawbacks of the above-mentioned conventional methods and to provide a construction method that can protect the slope by spraying concrete or the like and at the same time perform vegetation greening.

In order to achieve the above object, the present invention installs a plurality of seed tubes on the slopes of other mountains.

A structure is adopted in which concrete or mortar is sprayed on the outside of the seed tube.

By adopting the above-mentioned configuration, this invention can cover and protect the slope surface by spraying concrete or mortar, and at the same time, can carry out vegetation greening using seed cylinders, thereby making it possible to grow vegetation on the slope surface. It has the unique effect of preserving the natural beauty of greenery, restoring a beautiful environment, and improving the landscape.

One embodiment shown in one drawing will be described below.

In FIG. 1, reference numeral 1 denotes a ground consisting of bedrock, etc., and a wire mesh 2 is fixed to the slope by anchors 3. 4 is a drainage pipe, and 5 is a seed tube, which are made of a suitable material such as synthetic resin, and a plurality of these are each installed on the slope. A large number of small holes are drilled in the peripheral wall of the drain pipe 4, and through these small holes, spring water and seepage water are discharged from between the slope surface and the concrete or mortar to the surface of the concrete, etc. It is supposed to be done. The seed cylinder 5 has a hollow cylindrical shape with an open top and bottom, and its diameter is equal to that of the pipe 4.
As shown in Figure 2, the interior contains coarse sand (a) for water permeability and root rot prevention, and synthetic fertilizer (b) (nitrogen, N, etc.).

Fertilization 1. containing 0.5% of phosphoric acid (P% potassium) (mixed in a ratio of 6:4:3). Seeds d, which are an appropriate mixture of organic soil C, Kentara Key 31 fescue, clover, etc., are stored in paper bags and charged.6
Reference numeral 6 denotes concrete or mortar sprayed onto the outer slope surfaces of the drainage pipe 4 and the seed tube 5 by a spraying machine.

Next, the operation of the above embodiment will be explained according to the construction procedure. First, after leveling the slope of the ground 1, a wire mesh 2 is attached to it using anchors 3 to prevent concrete or mortar from falling off and from being partially destroyed by external force.

Anchors 3 are placed at important points and fixed so that the wire mesh 2 is in close contact with the slope. In particular, the upper end of the wire mesh 2 is carefully fixed so that it can sufficiently withstand the vertical load.

Next, a drainage pipe 4 is installed to prevent water inside the ground from stagnating on the slope, and a seed cylinder 5 is installed to carry out vegetation greening.
are arranged vertically and horizontally at predetermined intervals. The installation of these pipes 4, etc. is done by driving or by supporting them with other appropriate supports (not shown), and in the case of the drain pipe 4, the installation angle is at an angle where water flowing through the ground can be easily drained, that is, the same as the horizontal plane. , or so that the tip points slightly downward. On the other hand, in the case of the seed cylinder 5, when it is installed opposite to the drain pipe 4, the tip is made to face upward from the horizontal plane so that moisture is contained in the cylinder. Also, when installing the seed tube 5.

Either the soil or the like is charged into the cylinder in advance, or only the cylinder is installed. If only a tube is installed, concrete, etc. is sprayed and then soil, etc. is charged.

Next, concrete or mortar is sprayed onto the seed side of the drainage pipe 41 and the seed tube 5 on the slope surface using a spraying machine.

The thickness of spraying at this time is usually 7 to 7 for concrete.
In the case of 15 m1 mortar, the tip of the drain pipe 4 and seed tube 5 of about 5 to 10 crn should not be buried. As mentioned above, the drainage pipe 4 and the seed tubes 5 are already installed at the time of spraying, but this means that more than 10 seed tubes 5 are installed per spray.
When installing, spraying is effective in that the work can be done all at once, and if the number of installations is small, the worker may install the spray each time during the work. In addition, when spraying, to prevent concrete or the like from entering the seed tube 5, the upper opening of each seed tube 5 is stuffed with newspaper or the like and plugged, and the filling is removed after the work is completed.
Alternatively, as mentioned above, when the number of seeds installed is small, the operator places his foot on the upper opening of the seed tube 5 and closes the lid each time.

When the construction is completed, as shown in Figure 3, there are 7 vertical and horizontal holes on the surface of the concrete covering the slope.
The pipes 4 and the seed tubes 5 are arranged at predetermined intervals, and when the seed tubes 5 become hydrated, the paper bags inside the seed tubes are decomposed to promote the germination of the seeds, and the seed tubes are placed on the growing surface. Vegetation greening can be achieved through 5. Furthermore, if a large-volume seed tube is used, a large amount of soil can be stored, making it possible to revegetate rocky ground. In this way, by planting lush vegetation with flowers on the slope covered with concrete, etc., the slope is protected by preventing erosion caused by rainwater, controlling the humidity of the slope, preventing freezing, and further tying down the topsoil with roots. At the same time, an environment that preserves the natural beauty of greenery is created.

Note that the arrangement of the seed tubes 5 is not limited to the arrangement in which the seed tubes 5 are arranged at predetermined intervals vertically and horizontally between the drain pipe 4 and the drain pipe 4 as in the embodiment.1 For example, as shown in FIG. Arrange them in a three-fold circular pattern by themselves, or arrange them in a three-fold circular pattern as shown in Figure 5.
By arranging them in a rectangular pattern, pariages 7 of various geometric patterns can be created. Therefore, it is not only possible to simply make the violets flourish in the seed tubes 5, but also to create a green natural shoreline by utilizing various arrangements of the seed tubes 5.
