DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the prevention of scattering of the surface soil in the ground of kindergartens and elementary and junior high schools, various stadiums, etc. due to wind and the like, and the discharge of the surface soil due to rainfall. The present invention relates to a method of spraying a flocculant solution that achieves prevention of outflow of surface soil to prevent the occurrence of the problem, and reduction in the burden on the user's body by relaxing hardness of the surface soil. In addition, we aim at prevention of erosion and collapse of slopes at roads and tracks, rivers and lands, dams, etc.
The present invention relates to a method of spraying a flocculant solution that promotes stabilization of the slope.

[0002]

2. Description of the Related Art Conventionally, when the surface soil in the grounds of kindergartens and elementary and junior high schools, various stadiums, and the like, becomes dry, dust and dust is soared by wind and the like, which enters the eyes and throat and causes physical impairment. In addition, the dust fell on areas adjacent to the above-mentioned grounds and various stadiums, and had affected the local environment including indoors and outdoors. In addition, surface soil has flowed out together with water due to rainfall and the like, and the surface soil has moved, grooves have been formed, and irregularities have occurred, which has been a problem.

In order to avoid the above-mentioned adverse effects, various countermeasures against dust and hardening of surface soil have been taken. As a measure against dust, calcium chloride and magnesium chloride are sprayed on the surface. However, the above countermeasures are effective immediately after the implementation, but have the drawback that they are almost completely eliminated by the rain falling two or three times. Needed. Also, as a countermeasure against hardening, after raising the soil on the surface side by about several cm, it is compacted with a roller, but it takes labor and time like the above,
Needed a lot of expense.

Further, in order to prevent the above-mentioned soil dust or to prevent the outflow of the surface soil, a material having a high specific gravity is selected as the surface soil, and the surface soil is compacted. as a result,
When a user walks or exercises, the burden on the body is increased, which may cause damage to the legs and waist, and may cause a large injury when the user falls. In addition, in place of surface soil, untukers, chlorite powder, clay and rubber materials are used, and artificial turf is laid. Since it is made of a hard material, the recoil against the body is still large, and there is no change in that a load is applied to the legs and the waist. Furthermore, rainwater during rainfall will flow out to other places without being directly absorbed from the surface of the ground or various stadiums, etc., and the places will always be dry,
It contributed to the heat island phenomenon.

[0005] In addition, the slopes generated by civil works such as roads, tracks, rivers, lands, dams, etc., are left eroded by rain, wind, frost, frost damage, snow damage, etc. In order to prevent slope erosion and collapse by forming a retaining wall on the surface for earth retaining or adopting a greening method to protect the surface, Various earth retaining methods are adopted. The construction method of the retaining wall is to construct a retaining wall at the front position of the slope of the ground that has been cut, and backfill the backfill material between the back surface of the retaining wall and the slope to form the slope. I have. Such operations are time consuming and expensive. In addition, the completed slope has a surface made of concrete or stone exposed on the surface, and is not preferable from an environmental point of view because it is a dead scene and does not absorb rainwater from the surface.

In the method of greening the slope, a large amount of a synthetic resin emulsion is mixed and dispersed on a base material mainly composed of an organic substance such as bark compost and the like, and a resin film formed therefrom is formed. For stabilizing the slope, and a method for stabilizing the slope by adding cement or the like as a binder into the base material. Furthermore, clay soil having a water retention and fertilizing effect suitable for plant growth was sprayed on the slope.

[0007]

As described above, when the surface soil of a conventional ground or various sports fields uses ordinary soil in consideration of the influence on the body, dust enters the eyes and throat. In addition to the obstacles, dust and wind blows into the neighboring areas and the environment is degraded.On the other hand, if the surface soil is hardened to avoid them, it will require a lot of cost to form them, and the leg of the body This was a cause of increased burden on the head and lower back and injuries when falling. It was difficult to obtain a surface soil that satisfied both of the above.

The method of mixing a synthetic resin or cement into a base material or a base material has little effect as a vegetation base, and the method of spraying a clay-based material may cause the material to be clogged in a discharge pipe. In many cases, it caused interruption of work and failure of various devices. In order to prevent them, the water content of the clayey material is increased to increase the fluidity, but in that case, the material slips off the sloped slope and it is difficult to achieve the original purpose. Was.

[0009]

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The method of spraying a flocculant solution of the present invention is a method of spraying the flocculant solution on a surface soil of an object such as a flat surface or an inclined surface by a spraying device. This is a method in which particles of soil are combined with each other to form a particle mass, thereby improving the water permeability of the soil and increasing the porosity between the soils.

Hereinafter, a detailed description will be given based on embodiments.

[Embodiment 1] Description will be made based on an embodiment applied to a surface soil such as a ground or various stadiums. Generally, soil particles are negatively charged when viewed electrically. That is, the soil particles have negative ions, and when positive ions are given to the soil particles, ionic bonds are generated and the soil particles are combined with each other to become large particles. This phenomenon is collectively called agglomeration, and a substance having the above-mentioned positive ion is called an aggregating agent. As shown in FIG. 1, the aggregation reaction forms a three-dimensional network structure by further linking and bridging aggregates strongly bonded by electric charges. As a feature, the size of soil particles is about several tens of microns to 0, 3 mm.
And extremely large. In the combined state, it does not collapse even under severe natural phenomena such as rain, wind, pressure, etc., has extremely high physical strength, and is excellent in air permeability, water permeability, porosity and the like. Furthermore, since it is an ionic bonding reaction, a bonding phenomenon occurs instantaneously.

A material having a positive ion is used as the aggregating agent. As an example, a polymer compound containing polyethyleneimine as a main component is used. As the polymer compound, a complex of a magnesium salt of acrylic acid / dimethylaminoethyl methacrylate copolymer and polyethyleneimine is employed. The above substances are colorless and transparent water-soluble liquids, and are completely harmless in nature including humans, animals, plants, and the like. The dilution ratio between the aggregating agent and water is 50 to 100 times. As an optimal example used for a ground or the like, one having a size of about 50 times is used. Further, if necessary, the soil permeating activator may be diluted with a dilution factor of 1,000 to increase the aggregation effect.
Stir and melt at 2,000 times. As the above-mentioned soil-penetrating activator, a transparent liquid higher alcohol-based surfactant is used, but the soil-penetrating activator is also harmless to humans, animals and plants. Hereinafter, the aggregate-containing solution obtained by diluting the aggregate with water, a soil osmotic activator, or the like is referred to as an aggregate solution A.

FIG. 2 shows an apparatus for spraying the aggregating agent solution A. The aggregating agent solution A is sprayed on the surface soil by the spraying device 1. As shown in FIG. 2, the spraying device 1 includes a spraying liquid tank 2, a high-pressure pump body 3, a stirring device 4, a water absorption hose 5, a discharge pipe 6, a switching valve 7, a discharge hose 8, and a return hose 9. ing.

In the spray liquid tank 2, a flocculant comprising a polymer compound containing polyethyleneimine as a main component,
An aggregate solution A mixed with water and, if necessary, a soil osmotic activator is supplied. The aggregating agent solution A is applied to the spray liquid tank 2
As it is supplied to the tank, it precipitates at the bottom of the tank due to its weight. In order to prevent the sedimentation phenomenon, a stirring device 4 operated by the driving force of the high-pressure pump main body 3 is provided in the spray liquid tank 2. Agglomerating agent solution A by the stirring device 4
Is constantly agitated while the pump is running to prevent sedimentation,
The water is supplied to the high-pressure pump body 3 through the water absorption hose 5.

The high pressure pump body 3 has a pressure of 30 to 250K.
g / cm ² and a delivery rate of about 15 to 100 l / min are used. The spraying rate on the soil is 2 to 5 liters / m ² , and the spraying pressure at the time of spraying is within the range of the pump pressure.

The stirring device 4 uses one end of a shaft of the pump body 3 or a shaft serving as a drive source of an engine, a motor, or the like. One end of the hose is connected to the shaft, and the other end is equipped with a fan-type stirrer. The stirring device 4 at the tip is disposed in the spray liquid tank 2. In a state where the pump is in a driving state, the stirring device 4 also operates in conjunction therewith to stir the inside of the spray liquid tank 2 so that the uniformity of the aggregating agent solution A can always be ensured. Further, although the aggregating agent is water-soluble, it is easy to solidify when the stirring state is poor, and even if water or another solution is mixed with the aggregating agent, it will precipitate if left as it is. For this reason, the conventional agglomerated agent first requires a stock solution of the agglomerated agent
Two steps of diluting and mixing by a factor of 6 and further adding and diluting water to obtain a specified magnification were required. However, according to the method of the present invention, the aggregating agent solution A can be constantly stirred by the stirring device 4 linked to the driving of the pump, and the precipitation of the solution can be prevented.

The water-absorbing hose 5 connects the spray liquid tank 2 and the pump body 3 and conveys the aggregated agent solution A in the spray liquid tank 2 to the pump body 3. The water absorption hose 5 forms a filter for removing foreign substances. As the filter, a big filter 51 and / or a cyclone filter 52 are formed. As a filter means in the water absorbing hose of the conventional example, a water absorbing strainer 55 having a large diameter and a fine mesh was attached to the tip of the water absorbing hose provided in the spray liquid tank 2. Since the water absorbing strainer 55 has a fine mesh to prevent foreign substances from entering the water absorbing hose, the water absorbing strainer 55 is easily clogged and needs to be cleaned frequently. Movable operation had to be stopped and efficient operation was not possible.

The spraying apparatus 1 used in the present invention employs a coarse water absorbing strainer 55 which can remove relatively large foreign matters such as pebbles and dust at the tip of the water absorbing hose 5, and further includes a spray liquid tank 2 and a pump body 3 A filter is provided separately between them. The pump body 3 can function without any problem when there is no foreign matter when using tap water such as tap water. However, the spraying site using the aggregating agent solution A does not have a water supply facility or the like, and often uses water from lakes, marshes, and rivers. Further, when the aggregating agent solution A circulates through the inside of the pump body 3, foreign substances such as solids are generated.
Such foreign substances, such as chemical substances, block the mesh of the filter of the pump, causing a sudden drop in suction power, and impairing the normal functioning of the pump itself. Further, the foreign matter is also entangled in the packing inside the pump, which shortens the life of the pump. The big filter 51 and / or the cyclone filter 52 are used to remove the various foreign substances.
Use

The big filter 51 removes residual foreign substances such as algae having a small difference in specific gravity from water.
The provision of the filter 53 having a surface area three times as large as that of a normal filter makes it possible to eliminate adverse effects on the pump body 3. Further, since the surface area is large, even if a filter 53 having a mesh size of about 100 mesh is attached, foreign matter can be removed without lowering the suction force of the pump body 3. Further, since the big filter 51 has the filter 53 detachably mounted on the transparent case, the degree of clogging of the big filter 51 with foreign matter can be visually checked, and depending on the situation, the filter 5
By removing 3, foreign matter that has accumulated can be easily removed. The foreign matter can be easily removed without using a tool or the like.

The cyclone filter 52 can remove particles such as foreign matter having a specific gravity heavier than water. The cyclone filter 52 has a structure in which the aggregating agent solution A flowing from the water absorption hole in the casing 54 flows from the upper portion to the lower portion, from the outside to the center portion while rotating, and flows out from the discharge hole. Aggregate solution A
The foreign matter mixed therein moves and accumulates downward while being pressed against the inner wall of the casing 54 by centrifugal action caused by a difference in specific gravity with water, separates and accumulates on the bottom portion, and is more easily externalized from the lower portion of the casing 54. Can be discharged to The agglutinating agent solution A can be sucked into the pump main body 3 with the foreign matter in the aggregating agent solution A removed by the big filter 51 and / or the cyclone filter 52.

The discharge pipe 6 is formed in the pump body 3 and is connected to the discharge hose 8 for the aggregating agent solution A. By installing the switching valve 7 on the way and switching the switching valve 7, the aggregate agent solution A can be switched and discharged to the discharge hose 8 or the return hose 9. The diameter of the discharge hose 8 is 16φ
The above are used. The aggregate agent solution A discharged to the discharge hose 8 is ejected outward from the discharge nozzle 11 by the pressure of the pump body 3 by operating the lever of the gun type valve 10 attached to the tip of the discharge hose 8. Will be.

The switching valve 7 is formed in the middle of the discharge pipe 6 as described above, and switches the aggregated agent solution A discharged from the pump body 3 to the discharge hose 8 or the return hose 9 by the operation thereof. it can.

The conventional return hose 9 'shown in FIG. 2 uses the residual water to stir the aggregating agent solution A in the spray liquid tank 2, but uses the discharge pressure of the pump body 3. Cannot be performed, the injection pressure is extremely low, and only a stirrer for injecting in one direction by an injection nozzle is installed at the end of the return hose 9 ′. It was difficult to stir in time. Therefore, at present, another stirring device is used separately or stirring is performed manually. It is also possible to agitate the spray liquid tank 2 by using the injection pressure of the discharge nozzle section 11, but the spraying operation is stopped and the gun type valve 10 is pulled back to the pump body 3 side. The discharge nozzle section 11
This requires an operation of inserting the liquid into the spray liquid tank 2, which causes a time loss during construction and an increase in unnecessary work.

The return hose 9 of the spraying apparatus 1 used in the present invention returns the aggregating agent solution A discharged at a high pressure from the discharge port of the high-pressure pump body 3 to the spraying liquid tank 2 by switching the switching valve 7. It is possible. By attaching a jet spray nozzle to the end of the return hose 9, the high-pressure aggregating agent solution A is sprayed from the location, and the solution in the spray liquid tank 2 can be sufficiently stirred. For example, when diluting and mixing 10 liters of the aggregating agent with 1 ton of water, the ability of the pump body 3 can be used for the purpose of stirring the aggregating agent solution A in the spray liquid tank 2 without any change. It is possible to complete the dilution and mixing operation in 30 seconds.

Further, the spraying device used in the present invention uses a conventional return hose 9 ', and an adapter for injecting the aggregating agent solution A in three directions is attached to the stirring device 4' at the tip thereof. In addition, even when spraying the object in the spray liquid tank 2, it is possible to constantly circulate and stir, and the stirring state of the entire spray liquid tank 2 can be made uniform. The weight of the adapter prevents the return hose 9 'from jumping out of the spray liquid tank 2 due to the recoil during circulation of the aggregating agent solution A.

As shown in FIG. 3, the gun type valve 10
Is attached to the tip of the discharge hose 8, and the valve body 12,
Nozzle support pipe 13 and discharge nozzle section 11 at the forefront
And more. By operating the valve opening / closing operation lever 14 formed on the valve body 12, the aggregate solution A
Is ejected outward from the discharge nozzle unit 11. In the case of normal spraying, since there is no need for secondary mixing, it is not necessary to provide a mixing section in the discharge nozzle section 11. However, when the discharge hose 8 is longer than 100 m or when there is a height difference, the pump body 3 conveys the aggregating agent solution A at a pressure of about 40 to 50 kg / cm ^2, so that the target object such as soil is There is a possibility that the nozzle may be damaged by the pressure, and the discharge nozzle portion 11 has a structure for reducing the pressure immediately after the nozzle 16 is ejected in order to prevent the damage. In particular, when the aggregating agent solution A is mixed with another substance in the discharge nozzle section 11, the discharge nozzle section 11 includes the nozzle 16 and the mixing section 17 in the unit case 15 as shown in FIG. The pressure reducing unit 18 and the injection molding unit 19 are configured. The high-pressure aggregate solution A discharged from the nozzle 16 is supplied to the mixing section 17.
, And is decompressed by the decompression unit 18 and injected by the injection mode molding unit 19 in a predetermined form.

The aggregate agent solution A discharged from the discharge port of the nozzle 16 diffuses toward the front of the mixing section 17. The dispersed aggregating agent solution A is decompressed by the holes having the tapered surface gradually decreasing in diameter toward the tip and the injection form forming portion 19 and the like, and is diffused and ejected into the flat ejection form B. Therefore, the discharge hose 8 and the gun type valve 10
The aggregating agent solution A passing through can reduce the injection pressure on the object to be sprayed in the decompression section 18 of the discharge nozzle section 11, so that the object is not subjected to high pressure and damage is caused. It is not given, and the useless spraying is reduced, and the spraying can be surely performed to a predetermined place.

The ejection nozzle 11 can adjust the ejection pressure and the ejection mode B as appropriate, and is detachably attached to the tip of the nozzle support pipe 13 so that the ejection pressure and the ejection mode B can be adjusted. It is also possible to easily exchange ones having different performances. By adjusting or replacing the nozzle,
It is possible to easily change the flight distance, make the spray angle flexible (that is, select linear injection or curved injection as appropriate), change the spray particles, and the like. For example, regarding the scattering distance, when a pump having a flow rate of 60 l / min is used, the maximum flying distance is 25 m. In the case of a scattering distance of about 5 m, an object such as soil is disturbed by the linear injection, so that it is possible to spray without damaging the object by selecting the curved injection. As described above, it can be sprayed uniformly at all places, such as a site with a height difference such as a slope, a place with a wide area on a flat ground, and a place where both of them coexist. It becomes possible.

According to the present invention, during the spraying operation,
Even in the case where the operator of the manufacturing and application of the aggregating agent solution A and the spraying apparatus 1 promotes the preparation work for manufacturing the diluted mixed liquid of the aggregating agent in another spraying liquid tank 2 as the next work process. Thus, the next aggregating agent solution A can be manufactured without hindering the spraying operation, and preparation for the next spraying operation can be easily completed. FIG. 4 shows an embodiment in which the aggregating agent solution A is sprayed on the surface soil of a ground or various stadiums.

First, when there is little unevenness as an object to be constructed and the drainage gradient is secured or when there is no possibility that the user disturbs the surface soil due to spikes or the like, the surface soil is left as it is and the aggregating agent is used. It is sufficient to spray solution A only. In addition, in the case where the drainage gradient of a ground or the like is poor as an object to be constructed or in the case of a newly constructed ground, the construction is performed so that the sprayed aggregate solution A penetrates to the base surface of the soil and the aggregate effect is generated. . In this case, after about 3 to 5 cm of the surface soil is lifted to loosen the soil, the aggregate agent solution A is sprayed. Thereafter, predetermined compaction rolling is performed, the surface sand is sprayed, and the aggregating agent solution A is sprayed again. Even if the surface soil is compacted and rolled with a Macadam roller, a tire roller, or the like, the initial effect can be achieved without any change in the aggregation effect.

[0036]

[Embodiment 2] An embodiment in which a spray material is sprayed on a slope such as a road, a track, a river, a lands, and a dam will be described below. The same aggregating agent solution A as used in Example 1 is used as the spraying material. The dilution ratio between the aggregating agent and water is 50 to 100.
It is twice. The best example to use for the above slope etc. is 100
Around double is used. Further, in order to enhance the agglomeration effect, if necessary, a soil penetration activator may be diluted at a dilution ratio of 1,000.
Stir and melt as 2,000-fold. The soil permeating activator is a transparent liquid higher alcohol surfactant, which is harmless to humans, animals and plants. Further, as the spraying device 1 for spraying the aggregate solution A, the same device as in the first embodiment is used. The spraying device 1 includes a spraying liquid tank 2, a high-pressure pump main body 3, a stirring device 4, a water absorption hose 5, a discharge pipe 6, a switching valve 7, a discharge hose 8, and a return hose 9.

As shown in FIG. 5, the inclined slope collapses due to rain, wind, pressure and the like as shown in FIG. 5, but by spraying the aggregating agent solution A, as shown in FIG. The particles combine to form large agglomerated particles. The aggregation reaction further forms a three-dimensional network structure by further linking and cross-linking the aggregate strongly bonded by the electric charge, and in this state, it can collapse even under severe natural phenomena such as rain, wind, and pressure. And the strength of physical properties becomes extremely large. Furthermore, it is excellent in air permeability, water permeability, porosity, and the like. In addition, a bonding phenomenon occurs instantaneously because of the ionic bonding reaction.

[0038]

Embodiment 3 FIG. 7 shows an embodiment in which seeds are sprayed simultaneously for the purpose of stabilizing the slope in addition to the prevention of erosion and collapse by the aggregating agent solution A. The seeds are mixed at the discharge nozzle section 11 of the aggregating agent solution A. Seeds suitable for the construction site and construction time are selected, and the size is 8 m
Appropriate types up to about m are employed. The aggregating agent solution A is jetted from the nozzle 16 of the discharge nozzle section 11,
On the other hand, the seeds stored in the seed container 20 are sucked by the spraying force of the aggregating agent solution A from the nozzle 16 of the discharge nozzle unit 11 and mixed with the aggregating agent solution A. When the transport distance of the seeds exceeds 20 m, the seeds are pressure-fed to the seed discharge nozzle unit 22 by the pressure of the compressed air by the compressor 21. Since the discharge nozzle section 11 and the seed discharge nozzle section 22 are integrated or connected to each other, the aggregating agent solution A and the seed are mixed at the front end portion and dispersed on the inclined slope. The seeds sprayed on the slope remain at the spraying position due to the properties of the aggregating agent solution A, and even when the seeds are surrounded by the particles in which the soil particles are bound to each other by the aggregating agent, The particles bound by the granules are excellent in air permeability, water permeability, etc., and have a large porosity, so that they are suitable for growing them and grow as plants.

[0039]

Embodiment 4 FIG. 8 shows a nozzle section for mixing a fertilizer in addition to the mixing of the aggregating agent solution A and the seed. Like the above seeds, the powdered fertilizer and the like supplied from the fertilizer container 23 are sucked by the jetting force from the nozzle 16 of the discharge nozzle unit 11 of the aggregated agent solution A, and are mixed with the aggregated agent solution A. Become. When the conveying distance of the fertilizer exceeds 20 m, the fertilizer is fed to the fertilizer discharge nozzle 25 by the pressure of the compressed air by the compressor 24.
Since the discharge nozzle portion 11, the seed discharge nozzle portion 22, and the fertilizer discharge nozzle portion 25 are integrated or connected, the aggregating agent solution A, the seed, and the fertilizer are mixed at the tip portion, Sprinkled on sloped slopes. Liquid fertilizer is desirable as a fertilizer. In this embodiment, the aggregating agent solution A, the seed and the fertilizer are mixed in the mixing section 17 of the discharge nozzle section 11.
And promotes the growth of seeds sprayed on the sloped slope. Alternatively, the seed and the fertilizer may be mixed in advance, and both may be mixed with the aggregating agent solution A in the mixing section 17 by the method of the embodiment shown in FIG.
On the other hand, when the fertilizer is a liquid fertilizer, the fertilizer can be preliminarily mixed with the aggregating agent solution A in the spraying liquid tank 2, and in particular, the fertilizer container 23, the compressor 24, and the fertilizer discharge nozzle 25 for fertilizer. No such equipment is required.

[0041]

According to the present invention, it is possible to efficiently stir the inside of the spray liquid tank by using the driving force of the high-pressure pump serving as the spray apparatus. A granule solution can be obtained in a short time, and a solution suitable for spraying having fluidity can always be secured without causing precipitation of the granule solution in the tank.
