Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fabric method frame structure used in a slope method vegetation method, which enables easy and reliable execution of the method value value method. The purpose is to

[Conventional technology]

There are the following two construction methods in the conventional frame vegetation construction method. (1) A concrete frame block made of concrete, which is a molded product, is arranged and fixed in a lattice shape or other desired shape on the slope to fix and construct a slope frame on the slope, or a reinforcing bar is formed on the slope in a lattice shape. After arranging, concrete pouring is performed to construct a concrete legal frame, and the soil is brought into the legal frame and seeded, planted, sprayed with vegetation base material, or fitted with vegetation sandbags. (2) A cloth legal frame is devised, that is, it is composed of lattice-like communicating tubular portions and a sheet portion surrounded by the tubular portions. After laying this cloth law frame on the slope, press-filling fluid mortar or concrete into the tubular part to build a mortar or concrete law frame, and inside the law frame The same vegetation introduction technology as in (1) above has been adopted.

By the way, in the legal frame vegetation method of the above (1), it requires skill to construct a legal frame, and in the case of "law frame block", it is very difficult to bring in a heavy legal frame block on a steep slope. There is a danger in the combination work of the method frame blocks on a steep slope, the workability is poor, and in the case of "placing the concrete after placing the reinforcing bar", the reinforcing bar arranging work on the steep slope is also difficult and dangerous. It has become a habit.
In addition, when the soil is brought in and planted, or when the vegetation base material is sprayed, the technique of introducing vegetation into the legal framework may be subject to heavy rainfall immediately after the construction. However, there is a drawback that the soil and planted material that has been carried in is washed away, and when vegetation sandbags are brought in, there is no runoff of vegetation base material due to rainfall, but it is not easy to bring in heavy vegetation sandbags on steep slopes There was a drawback. the above
In the case of the cloth legal frame of (2), there is no problem in constructing the legal frame, but when introducing vegetation into the legal frame, one sheet part surrounded by the legal frame is used. It must be cut and cut along the legal framework. Therefore, the work of forming the opening in the above-mentioned legal frame must be performed on the slope,
It had the drawback that its work efficiency was also very poor.

What was invented there was the "slope method of vegetation method for slopes" disclosed in JP-A-60-119822. The present invention is a "communicating cloth-made method frame constituting cylinder for filling a mortar or concrete to form a method frame, and a vegetation base material in a method frame surrounded by the method frame constituting cylinder. After laying on the slope, a legal frame vegetation structure that is integrally provided with a vegetation structure bag body made of cloth for filling and forming a vegetation part,
A fluid mortar or concrete is press-fitted into the cylinder for constructing the method frame, a mortar or concrete method frame is constructed on the slope, and then a fluid vegetation base material is added to the bag for vegetation composition. It was characterized by constructing a vegetation part within the legal frame by press-fitting and filling. However, a new problem arose in this "slope method of vegetation." It is a problem that the seeds in the vegetation base material press-filled into the bag for vegetation composition sprout and the plant grows and grows, but the plant near the periphery of the law frame will die. Is. This is caused by the formation of voids at the boundary between the law frame and the vegetation base material filled in the vegetation composition bag (corresponding to the boundary between the bulging part and the bulging part of the air mat used for sea bathing, etc.). Since it becomes easy to dry in the vicinity of the void and the root floats from the slope, it becomes an environment unsuitable for plant growth. Is.

[Problems to be solved by the invention]

Therefore, the present inventor does not need the work of cutting the cloth portion of the law frame of the cloth method on the slope, of course, and the cloth method frame configuration in which the plant life in the law frame does not die. In order to provide the body, various researches have been carried out, and the present invention has been completed here.

[Means for Solving Problems] and [Operation] That is, according to the present invention, a continuous cloth-made method frame constituting cylinder 1 for forming a method frame by filling mortar or concrete.
And a net body 2 for spraying a vegetation base material, which comprises a net having an area of mesh 5 mm ² or more and having a fixed intersection at which the warp and the weft are fixed. Is a fabric manufacturing method frame structure A.

The details of the present invention will be described below.

The cloth-made method frame vegetation structure A is composed of a cloth-made method frame forming cylinder 1 and a vegetation base material spraying net body 2, and as shown in FIG. This tubular portion is used as a cloth-made method frame forming tubular body 1, and the inside of each frame surrounded by the tubular portion is used as a vegetation base material spraying net body 2. Cylinder body 1 made of cloth
Is for fluid mortar or concrete press-fit filling,
Mortar or concrete after molding, which is a part forming the frame block, has a diameter of 5 to 50 cm, preferably 1
Configure to be 0 to 25 cm. If it is 5 cm or less, the strength of the mortar or concrete is insufficient and sufficient slope protection cannot be performed, and if it is 50 cm or more, the strength is excessive and the amount of mortar or concrete is large, which is uneconomical.

The cloth of the tubular frame 1 for forming the framework is 5 as strength that can withstand the press-filling pressure of fluid mortar or concrete.
Those with a width of 0 kg / inch or more also have a good filter bed effect, that is, a mortar or concrete outflow preventive property and a surplus water discharge property, an opening area of 0.01 to 1.0 m when expressed by numbers.
Those having a texture of m ² are preferred. If it is less than 0.01 mm ² , problems such as delayed hardening of mortar or concrete and poor discharge of excess water will occur, and if it is more than 1.0 mm ^2, there will be damage to the cloth during press-filling of fluid mortar or concrete, large amounts of mortar or concrete flowing out, and insufficient consolidation. It causes problems and is not desirable.

The vegetation base material spraying net body 2 has a fluidity obtained by mixing seeds, soil, fibers, fertilizers, etc. with water when a slope revegetation work is carried out using the cloth method frame structure A of the present invention. This is a part for spraying the vegetation base material for vegetation, which is extremely effective in retaining the vegetation base material. That is, the sprayed vegetative base material passes through the mesh of the net floating in the air from the slope to reach the slope, and as the thickness increases, the vegetative base becomes a vegetation base material for spraying. Since it is caught in the net body, there is no outflow of vegetation base material, and seed germination and growth are extremely good.

The opening area of the mesh of the vegetation base material spraying net body 2 is necessary for the area of 5 mm ² or more to pass through the sprayed vegetation base material. Below this, the sprayed vegetation base material forms a mesh. Since it does not pass, it rides on the net, the net forms a boundary between the slope and the vegetation base material, the vegetation base material floats from the slope and flows out, and the rooting of vegetation is bad. Become.

When the vegetation base material spraying net body 2 is a quadrangle, one side is 20 to 15
The size is 0 cm. If it is less than 20 cm, the amount of mortar or concrete in the legal frame increases, which is uneconomical and looks bad. If the length is 150 cm or more, the mortar or concrete portion of the slope is reduced and the slope protection effect is reduced. In addition, the stroke of the mortar or concrete beam becomes large, and the mortar or concrete beam in the row is bent, resulting in poor appearance.

A more preferable opening area of the mesh is 100 to 1000.
mm ² . As the open area of the mesh increases, the water content of the vegetation base material to be sprayed is reduced.

There is no particular limitation on the material of the cloth-made cylinder 1 for forming the framework,
The part located on the slope side of the cylinder should be made of a cloth with low extensibility, and the top surface of the cylinder should be made of a cloth with a lot of expansion, so that when the mortar or concrete is filled, the bottom surface of the cylinder does not swell and sticks to the ground. It may or may not be devised.

The cloth-made method-frame-forming cylinder 1 and the vegetation base material spraying net body 2 can be continuously produced by a knitting machine, but the production is not limited to this.

It is the same as a known one that the mortar or concrete injection port for injecting a fluid mortar or concrete is provided in a suitable place in the cloth-made method frame constituting cylinder 1.

Next, a method of using the fabric manufacturing method frame structure A of the present invention will be described.

If there is an obstacle on the construction slope, remove it to prepare the slope. Next, the cloth manufacturing method frame structure A is stretched on the slope. For tensioning, fix the appropriate place on the slope using an anchor or the like. When the slope of the slope is steep, the upper end of the fabric manufacturing method frame structure A is pulled by a chain block. When the slope is wide, an appropriate number of legal framework vegetation structures A are stretched vertically and horizontally. Next, the tank of the mortar or concrete press-fitting machine is filled with the fluid mortar or concrete, and the tip of the nozzle provided at the tip of the hose of the filling machine is mortar or concrete provided on the cloth-forming method frame forming cylinder A. Insert into the inlet and operate the mortar or concrete press-filling machine to press-fill mortar or concrete. The press-fitted mortar or concrete flows downward by its weight, then flows laterally, and sequentially fills the cloth-made method frame constituting cylinder 1 from bottom to top with mortar or concrete. When the mortar or concrete injecting mortar or concrete rises up to the vicinity of the cloth-made method frame constituting cylinder 1, the nozzle cock is tightened, the nozzle is pulled out from the injection port, and the injection port is sealed. Next, insert a nozzle into the mortar or concrete injection port provided above the injection port in the same manner as described above, press-fill with mortar or concrete, and finally insert the nozzle into the injection port provided in the uppermost stage. Mortar or concrete is spread all over the cloth-made method frame-constituting cylinder 1 while press-fitting and filling. Then, the nozzle is pulled out and the injection port is sealed as described above. This completes the legal framework. At this time, the mesh body surrounded by the method frame rises from the slope because the method frame constituting cylinder 1 made of cloth swells with mortar or concrete. When the width of the mat is wide, several injection ports are provided in the width direction as well, and press-filling is performed from all the injection ports in the width direction downward to all the injection ports in the width direction upward.

Without waiting for the mortar or concrete in the above-mentioned frame to harden (of course, you may wait), until the net covers the fluid vegetation base material from above the vegetation base spray net 2.
Operate the spray machine and spray.

Similarly, the vegetation base material is sprayed on all the portions of the net body 2 for spraying the vegetation base material.

The shape of the vegetation base material spraying net body 2 may be a rhombus or a circle as shown in FIGS.

〔The invention's effect〕

The fabric manufacturing method frame structure A according to the present invention is as described above. When the method frame vegetation method is carried out using the same, the inside of the method frame has a mesh with an opening area of 5 mm ² or more, and the warp and the weft. Since the net body 2 for spraying vegetation base material is made of a net in which each intersection with and is fixed, the warp and the weft even if the cloth for forming the legal frame 1 is filled with mortar or concrete and a load is applied. Since the vegetation base material spraying net body 2 made of a net in which each intersection with and is fixed is maintained in a vertically stretched state, the mesh has a substantially uniform opening,
When the vegetation base material is directly sprayed from above the vegetation base material spraying net body 2, the vegetation base material is uniformly distributed on the slope through the mesh having the substantially uniform openings. The vegetation method can be easily and reliably constructed.
