Abstract

PURPOSE:To stabilize the natural ground by directly setting a decayable vegetable fibre block on the ground. CONSTITUTION:Decayable vagetable fibre blocks 5 whose ends are branched, containing humus, clay, and fertilizer, are contacted with natural ground and fixed to the metal netting 8, anchors 3, and retardation tubes 4 on a slope 1, and covered with concrete. The natural ground can thus be stabilized because the roots of plants can easily permeate the ground.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a construction method for afforestation infrastructure, and more particularly, to a construction method for afforestation infrastructure that can stabilize the ground by encircling the root system over a wide area.

[Background of the Invention] Conventionally, various attempts have been made in greening infrastructure construction methods for slopes in order to attach seeds to steep slopes and enable good greening.

For example, Japanese Patent Publication No. 81-58388 uses a net-like structure for vegetation in which vegetation material serving as a greening base is housed in rows of pockets or partially formed pockets. A construction method that can be constructed is disclosed. However, this method does not protect the slope surface by integrating the plants and the ground, and the root system is only concentrated in rows or partial pockets, so it has the disadvantage that it cannot stabilize the ground. Japanese Patent Publication No. 55-126813 and Japanese Patent Publication No. 59-88431 disclose a technique using a vegetation body instead of the above-mentioned vegetation net-like body.
Similar to the above, there is a drawback that the root system does not spread and the ground cannot be stabilized. Furthermore, Japanese Patent Application Laid-open No. 53-53102 discloses that a vegetation base material made of straw woven with string and straw woven into a blind shape is spread on a bedrock etc. to cover it and prevent it from falling. A construction method has been disclosed in which a net is covered and sprayed with curing seeds, etc. to make it green. However, with this construction method, all the vegetation base materials - curing soil, seeds, etc. are fixed to the slope using only wire mesh and anchors, and the disadvantage is that if the wire mesh or anchors corrode on steep slopes, it becomes dangerous and cannot be used. be.

In addition, it takes time and effort to weave straw, etc., and weave it into a blind shape.
It has the disadvantage that it is expensive to lay it all over the slope. Furthermore, since the soil is sprayed onto a base of straw or the like, the foundation for greening is soft, making it difficult to stabilize plants against wind damage.

[Purpose of the Invention] Therefore, the purpose of the present invention is to provide a method for constructing a greening foundation that can stabilize the ground, safely form a greening foundation even on steep slopes, be low-cost, and allow stable vegetation against wind damage. Our goal is to provide the following.

[Means for Solving the Problems] The present inventor has made extensive studies to achieve the above object, and as a result, has arrived at the present invention.

That is, 1. The method for constructing a greening infrastructure according to the present invention is to place corrosive plant fibers containing at least humus soil, clay, and fertilizer and having branched ends in contact with the ground using wire mesh, anchors, drainage anchors, and stagnation on slopes. It is characterized by being fixed to water pipes and covered with concrete.

[Specific Structure] The corrosive plant fiber strain of the present invention contains at least humus soil, clay, and fertilizer, and has branched ends. The method for producing this corrosive plant fiber strain is not particularly limited, but for example, rice straw may be lined up horizontally, and humus soil, clay, fertilizer, etc. may be sprinkled on top of the rice straw in several tiers.

It is formed by bundling rotten plant fibers with corrosive strings after being sprinkled with water and left to rot for a certain period of time. That is, FIG. 1 shows a perspective view showing one form of the corrosive plant fiber strain obtained in this way, and in the same figure, lO
is the head of a corrosive plant fiber strain containing humus soil, clay, fertilizer, etc., 20 is a branched leg for promoting root threads, and 30 is a member for bundling the straw (for example, thread) It is.

Although rice straw was used in the above, wheat straw, silver grass stems, etc. can also be used.

As the humus soil, clay, and fertilizer contained in the corrosive plant fiber strain, known ones can be used, and in addition to these, organic fertilizers may also be contained.

In the case of straw, the branched legs correspond to the tips of the straw.

The construction method for constructing a greening infrastructure using the above-mentioned corrosive plant fibers will be explained in detail based on Figs. Construct and secure wire mesh, reinforcing bars 8, etc. In addition, in extremely dry ground, it is impossible to replenish water, so a water retaining pipe 4 or the like is installed.

Next, corrosive plant am strain 5 is installed so as to surround the drain pipe 2, anchor 3, water retaining pipe 4, etc.

Next, spray concrete such as water-permeable shotcrete to form the greening base 6. In the present invention, ordinary concrete other than water-permeable concrete may be used, and the concrete base may be formed by a method other than spraying. You can also do it. Seeds may be mixed into this concrete.

Next, a tree is planted on the male plant of the saprophytic plant. If the permeable shotcrete does not contain seeds, spray the seeds as necessary.

As shown in FIG. 3, the planted plants 9 spread their roots 7 all over the slope, and also partially penetrate into the bedrock, etc., so that they stably exist on the slope.

A greening base can be formed in the above manner.

[Operations and Effects of the Invention] According to the present invention, corrosive plants! @Since the male plants are placed in direct contact with the ground, the plant's root hair system can easily penetrate into the ground, stabilizing the ground.

In addition, since the corrosive plant fiber stocks are made to rot in advance and become a greening base, the planting can be done immediately.

Furthermore, corrosive plant fiber strains are arranged with consideration to the growth of plant roots, so the roots can grow freely and the plants will not fall over due to wind, etc. Water is supplied from drainage anchors and water retention pipes installed by drilling holes in the slope, so it does not become sticky due to dryness, and plant roots can enter the drainage holes and crevices of the rocks, preventing them from forming into the ground. Reinforce as one. Furthermore, the position of the corrosive plant fiber strain can be arbitrarily determined depending on the unevenness and humidity of the slope, and the selection can be made in accordance with the actual natural conditions.
