Abstract

PURPOSE:To easily and exactly construct slope frames made of fabric by a method in which a slope frame material is made up of a fabric slope frame- forming cylinder and a net having more than a specific area for the area surrounded by the cylinder. CONSTITUTION:A fabric slope frame material A is made up of a fabric slope frame-forming cylinder 1 to be filled with cement mortar, etc., and a net 2 having an area of 5mm<2> or more surrounded by the cylinder 1, which is to be sprayed with a vegetating base. Since the vegetating base reaches through the mesh of the net 2 to slope and grows in an entangled state on the net 2, the run-off of the vegetating base can be prevented and the germination and growth of seeds can be improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fabric method frame structure used in the slope slope vegetation method, and is designed to enable easy and reliable construction of the slope slope vegetation method. It is intended to.

[Conventional technology]

There are two conventional methods for constructing slope vegetation, as shown below. (1) Build a slope on the slope by placing and fixing the concrete slope blocks, which are molded products, in a lattice or other shape on the slope, or install reinforcing bars on the slope in a lattice pattern. After placing the concrete, pour concrete, construct a concrete legal framework, bring soil into the legal framework, sow and plant, spray with vegetation base material, or use vegetation sandbags. Technological measures such as inlaying were adopted, and (2) a cloth frame was devised, consisting of a lattice-like cylindrical section that communicated with each other and a sheet section surrounded by the cylindrical sections. After this cloth slope is stretched over the slope, fluid mortar or concrete is press-filled into the cylindrical part to construct a mortar or concrete slope, and then placed inside the slope. The same technical means of introducing vegetation as in (1) above have been adopted.

By the way, in the slope vegetation method (1) above, skill is required to construct the slope, and in the case of using ``slope blocks'', it is difficult to carry the heavy slope blocks onto a steep slope. Assembling the legal frame blocks on a steep slope is often dangerous and has poor workability, and when concrete is poured after placing the reinforcing bars, the work of placing the reinforcing bars on a steep slope is difficult and dangerous. It has become a constant. In addition, technical methods for introducing vegetation into the legal framework may be used, such as when soil is brought in and planted, or when vegetation base material is sprayed. However, the disadvantage is that the soil and plants carried in will be washed away, and although the vegetation base material will not be washed away due to rain when carrying in vegetated sandbags, it is not easy to carry heavy vegetated sandbags onto steep slopes. There was a drawback. In the case of (2) above, where the cloth frame is used, there is no problem in constructing the frame, but when introducing vegetation into the frame,
One sheet surrounded by the legal frame must be cut out by cutting along the legal frame. Therefore, the work of forming the opening in the slope must be performed on the slope, which has the disadvantage that the work efficiency is very poor.

Therefore, the "slope slope vegetation method" disclosed in Japanese Patent Application Laid-Open No. 119822/1982 was invented. This invention is based on the following technology: ``A cylindrical body made of continuous cloth for constructing a gantry frame filled with mortar or concrete, and a vegetation base material in the cylindrical frame surrounded by the cylindrical body for structuring a legal frame. After the slope vegetation structure, which is integrally provided with a cloth vegetation structure bag to be filled to form a vegetation section, is stretched on the slope.
A mortar or concrete legal framework is constructed on the slope by press-filling fluid mortar or concrete into the cylinder for constructing the legal frame, and then a fluid vegetation base material is placed inside the bag for constructing the vegetation. This method was characterized by the construction of vegetation within the legal framework by press-filling the soil. However, a new problem arose with this ``slope slope vegetation method.'' This is said to be a phenomenon in which the seeds in the vegetation base material press-fitted into the vegetation-containing bag sprout, and eventually the plants grow and flourish, but the plants near the periphery of the field frame wither and die. That's a problem. The cause of this is that a void is created at the boundary between the legal frame and the vegetation base material filled in the vegetation-containing bag (equivalent to the boundary between the bulges of an air mat used for sea bathing, etc.). As a result, the area around the void becomes prone to drying out, and the roots float above the slope, creating an environment unsuitable for plant growth. It is.

[Problem that the invention seeks to solve]

Therefore, the present inventor created a cloth manufacturing method frame structure that not only does not require the work of cutting out the cloth part within the frame on the slope, but also prevents plants within the method frame from withering and dying. In an effort to donate the human body, we have conducted various studies and finally completed the present invention.

[Means for Solving the Problems] and [Operation] That is, the present invention provides a communicating cylinder for forming a legal frame made of cloth [1] for forming a legal frame by filling with mortar or concrete, and the above-mentioned legal frame. This is a cloth manufacturing method frame structure A consisting of a net-like body for spraying a vegetation base material [2] which is a net having an area of 5 Yuri 5 Dragon 2 or more in the frame surrounded by the structuring cylinder body [1].

The present invention will be explained in detail below.

The cloth-made method frame vegetation structure A consists of a cloth-made method frame-constituting cylinder [1] and a vegetation base material spraying net-like body (2), and as shown in Fig. 1, each cylinder part is connected in a grid pattern. This cylindrical part is made into a cloth-made legal frame-constituting cylinder [1], and each frame surrounded by the cylindrical part is made into a net-like body (2) for spraying a vegetation base material.

The cylindrical body for constructing a legal frame made of cloth (2) is a part that forms a legal frame block body for use in fluid mortar or concrete press-in filling, and the diameter of the mortar or concrete after molding is 5 to 50 cm, preferably 10 to 50 cm. Configure it so that it is 25 cm. If the thickness is less than 5 cm, the strength of the mortar or concrete will be insufficient and it will not be possible to provide sufficient slope protection.
A cI of 11 or more results in excessive strength and requires a large amount of mortar or concrete, which is uneconomical.

The fabric of the cloth cylinder for constructing the legal frame (■) has a strength of 5 to withstand the pressure of fluid mortar or concrete.
Those with a width of 0 kg/inch or more are also those with a good filter bed effect, that is, the ability to prevent mortar or concrete from flowing out and the ability to drain excess water, expressed in numbers from 0.01 to 1.0.
A lily with an area of 11I” is preferred.0.0
If it is less than 1 dragon, the hardening of mortar or concrete will be delayed,
Problems such as poor drainage of surplus water occur, and if it exceeds 1.0 tm'', problems such as damage to fabric, large amount of mortar or concrete flowing out, and insufficient compaction occur during press-filling of fluid mortar or concrete, which is undesirable.

The net-like body (■) for spraying a vegetation base material is a fabric manufacturing method frame structure A of the present invention.
When constructing slope greening using
This is the part where a fluid vegetation base material mixed with water such as fibers and fertilizers is sprayed, and this is the part where vegetation is intended to be made, and it is extremely effective in retaining the vegetation base material.

In other words, the sprayed vegetation substrate passes through the mesh of the net-like material suspended in the air from the slope surface, reaches the slope surface, and as the net-like material increases in thickness, the net-like material becomes thicker. Since the plant is caught in the body, there is no outflow of the vegetation base material, and the germination and growth of seeds is extremely good.

The lily of the rope-shaped body for spraying vegetation substrate ■ requires an area of 5 m” or more in order to pass through the sprayed vegetation substrate,
Below this point, the sprayed vegetation base material does not pass through the mesh, so it ends up on top of the mesh, and the mesh creates a boundary between the slope and the vegetation base, causing the vegetation base to move away from the slope. It floats, washes away, and makes it difficult for plants to take root.

Net-like body for spraying vegetation base material ■ is square if the sides are 20 to 1
The size shall be 50cm. If it is less than 20 cm, there will be a lot of mortar or concrete part of the frame (which is uneconomical,
It looks bad, and if it is over 150ca+, the mortar or concrete part of the slope will be reduced, and the slope protection effect will be low (
Also, the stroke of the mortar or concrete beam becomes large, causing deflection in the horizontal rows of mortar or concrete beams, resulting in poor appearance.

A more preferable lily has an area of 100 to 1000 m''. The larger the lily, the less moisture the vegetation substrate is sprayed with.

The material of the cloth cylinder for forming the legal frame ■ is not particularly limited;
The part of the cylinder located on the slope side is made of cloth with low elasticity, and the top surface of the cylinder is made of cloth with high elasticity, so that when filled with mortar or concrete, the bottom surface of the cylinder will not swell and will stick to the ground. You may or may not devise ways to do so.

Cloth cylinder for constructing a legal frame [1] and net-like body for spraying vegetation base ■
can be produced continuously using a knitting machine, but manufacturing is not limited to this.

Similar to known cylinders, mortar or concrete injection ports for injecting fluid mortar or concrete are provided at appropriate locations on the cloth-made legal frame-constituting cylinder (2).

Next, how to use the cloth manufacturing frame structure A of the present invention will be explained.

If there are any obstacles on the surface of the construction slope, remove them and prepare the slope. Next, install the fabric method frame structure A on the slope. etc. to fix it on the slope.If the slope is steep, use the fabric method frame structure A.
Pull the upper end with a cemburo tsuku (.If the slope is wide, install an appropriate number of slope vegetation structures A in the vertical and horizontal directions.Next, pour fluid mortar or concrete into the tank of the mortar or concrete injection filling machine. Fill with concrete, insert the tip of the nozzle provided at the end of the hose of this filling machine into the mortar or concrete injection port provided in the cloth-made legal frame construction cylinder A, and operate the mortar or concrete press-in filling machine. , mortar or concrete is press-fitted.The press-fitted mortar or concrete flows downward due to its weight, and then flows laterally, and the mortar or concrete is sequentially filled from the bottom to the top of the cloth cylindrical frame ■. When the mortar or concrete is injected into the mortar or concrete cylinder made of cloth with a mortar or concrete injection port, tighten the nozzle cock and insert the nozzle from the injection port. Next, insert the nozzle into the mortar or concrete injection port provided above the injection port and press-fill the mortar or concrete. Insert the nozzle into the injection port and spread the mortar or concrete over the entirety of the cloth cylindrical frame 2 while press-fitting.

Next, remove the nozzle and seal the injection port in the same manner as above. The legal frame is now complete. At this time, the net-like body surrounded by the slope rises from the slope because the cloth cylinder for forming the slope (2) swells with mortar or concrete. If the width of the mat is wide, several injection ports are provided in the width direction, and the filling is performed by press-fitting from all the injection ports in the width direction at the bottom to the top from all the injection ports in the width direction.

Without waiting for the mortar or concrete of the above-mentioned legal frame to harden (of course, you can wait), next spray the fluid vegetation base material from above the vegetation base material spraying netting material until the netting body covers it. Operate the machine and spray.

In the same manner, the vegetation base material is sprayed onto all of the vegetation base material spraying net-like bodies (3).

Note that the shape of the net-like body (2) for spraying the vegetation base material may be a diamond shape, a circle, or any other shape as shown in FIG. 2.3.

〔Effect of the invention〕

The fabric method frame structure A according to the present invention is as described above, and when using this to implement the method of constructing a method of planting vegetation, the inside of the method frame consists of a net having a mesh area of 5 m or more. Since it is made of the net-like body for spraying base material (■), the vegetation base material can be sprayed directly over the net-like body (for spraying vegetation base material) ■, making it possible to easily and reliably perform the construction of the slope vegetation method. It becomes like this.
