TECHNICAL FIELD The present invention relates to greening powder for recording of rock mass, and more particularly, to greening powder used for surface greening of mined stone wall or rock reflecting surface.

Quarry development sites are exposed to rock slopes and cause environmental and economic damage. Earth and sand disasters are caused by the generation and collapse of scattered dust on rock slopes, which provides the cause of opposition to the development of stone from residents and environmental protection organizations.

In the past, the rock slopes were often neglected, but recently, the damaged ecosystems such as landscape recovery of toll highways, greening of suburban roads, harmony with the surrounding environment after quarrying at the quarry, and the beautification of the park's incisions are maximized. It is the emotion of the people

Rock slopes due to the development of stony mountains are sloping and weathered due to their physical characteristics, which makes them difficult to settle and grow even when planting of herbs or trees, and surface erosion due to water penetration into joints and delamination gaps during rainfall. Over collapse is occurring frequently.

Since the inclined slope and damaged area have a long time to be restored by natural force due to the poor growth base of vegetation, these slopes are using sowing and planting methods for the initial vegetation covering and greening. For the greening of the rock cut slope consisting of mechanical force, the vegetation of green soil and sprinkling soil is used in the vegetation base material mixed with artificial soil, organic fertilizer and inorganic fertilizer, and plant seeds such as sheep grass and grasses. To record.

It is true that the rust and soil spraying methods that have been constructed in Korea so far cause problems such as cracking and collapse of the soil layer and soil and water pollution due to the lack of cost and insufficient soil materials. In addition, the greening site also raises issues such as heterogeneous landscapes due to the invasion of exotic plants used for early vegetation cover, and ecological discontinuities with surrounding vegetation.

In general, the greening method has been used to create a vegetation-based condition by drilling on the rock slope to grind the anchor in the perforation, grouting, covering the ridge wire mesh and spray-gluing the cultured soil to a thickness of 5 to 10 cm by using an applicator. In addition, install an attachment network (net size 5 × 5cm) on the rock slope, install fixed wire at 3m horizontally and 1.5m vertically, and then drill the ground to fix the attachment network with anchor pins, and then plant the trees on the attachment network. Pots (5 cm high and wide) were inserted, and herbaceous seeds were mixed with the vegetation base and adhesive on the attachment network, and the pots were made invisible by 8 cm thickness.

However, this method sprays 5-10 cm thick culture soil onto the entire surface of the rock slopes. Therefore, the stability of rock slopes due to the increase of the weight of the culture soil and rainwater infiltrate the cracks of the culture soils during rainfall are the paths between the bedrock and the culture soil. There is a problem of peeling phenomenon of cultured soil, which causes loss of cultured soil due to adhesion life (adhesiveness) of cultured soil, damage of exposed ridge wire and anchor, and the risk of collapse. have.

In particular, the method of recording the slope by drilling the rhomboid wire and anchor in the hole after drilling had to be used only in the place where the rock quality was safe, and there was a concern that the landscape would be damaged rather than the exposed rock slope without continuous maintenance. In addition, the main purpose was to support the rock bolt or anchor to stabilize the slope of the rock slope collapse.

In the case of rock slopes, unlike general inclined slopes and dams, there is no soil to settle. Therefore, it is necessary to create a vegetation base material artificially through the above-described methods such as spraying the whole acre soil and rust soil. It requires a lot of maintenance and requires continuous maintenance, which is not good for environmental and economic aspects.

Accordingly, the present invention is to solve the problems that are applied in the same way regardless of the quality of the slope to record rock slopes as described above, and difficult to expect stability and greening effect by the existing method, rock bed The purpose of this study is to develop rock slopes that can achieve the stability of rock slopes itself and early recording by plants.

According to the invention,

In the greening which consists of a plant growth part and a drain,

The plant growth portion is formed to less than 1/2 of the total length of the greening,

The drain holes are provided at the bottom of the greening powder in 1-10 pieces with a diameter of 8 to 10 mm.

Hereinafter, with reference to the accompanying drawings 1 to 3 of the present invention will be described in detail.

As the material of the greening powder (1,1 ′) of the present invention, one or more selected from materials such as soil (ocher and clay), PVC, plastic, rubber, etc. are used depending on the nature of the slope. At this time, the greening powder (1,1 ') is suitable to be inserted into the perforated rock slope, the size of the growth base (ie, the size and depth of the perforation), direct sunlight, wind resistant, ease of transport, waterproofing, vegetation It is recommended to select five factors including the minimum soil depth that can be grown.

At this time, the size of the greening powder (1,1 ') is characterized by the technology of manufacturing the greening powder to a certain size so that the manufactured rock greening powder can be put into the perforated hole, and if the diameter fits into the perforated hole in the greening base, Suffice.

Preferably, the greening powder (1,1 ') is not limited thereto, but has a circular cylindrical shape and a rectangular shape, and preferably has a total length of 200 to 1,000 mm and a diameter of 100 to 500 mm. , 10 ') is formed to have a length of 100 to 500 mm, and at the bottom thereof, drain holes 11 and 11' having a diameter of 8 to 10 mm are formed within the range of 1 to 10.

Particularly, in the case of the circular greening powder 1, the grooves 12 such as horizontal (-), vertical (|), U-shape, and V-shape (V) -shaped grooves 1 to 1 are used for inducing root drainage and drainage at the rear part. Equipped with five, it is characterized by facilitating the supply of light and moisture by protruding out of the rock slopes. At this time, the shape of the groove 12 is four types selected from the horizontal (-), vertical (|), U-shape (V), V-shape (∨), the slope is left and right relative to the center line of the greening (1) It is good that it is 0-90 degrees. In particular, the grooves affected by the slope are V-shaped, wherein the angle of the V-shaped is preferably maintained at 30 ~ 60 °. In addition, the horizontal (-), vertical (|), and U-shaped (∪) are not affected by the inclination much. In addition to this, a diagonal (/), which is a variation of the horizontal and vertical, may be used depending on the place. .

The shape and the inclination of the grooves 12 described above can be selected according to the amount of water supplied at the place where the greening powder is to be mounted. In consideration of the convenience, it is good to select the (∪) or (∨) type groove in the area where water supply is easy and easy water supply is considered.

In addition, the number of such grooves 12 is not limited to this, but it is enough to install about 1 to 5, it can be selected flexibly depending on the water supply. As an example, when the water supply is difficult, and five grooves 12 are applied to the greening powder 1, they are positioned at 180 °, 225 °, 270 °, 315 °, and 360 ° by symmetry with respect to the horizontal line of the greening center. You can.

As a result, in the case of the circular greening powder 1, the drainage port 11 and the groove 12 are formed together to facilitate the drainage.

In particular, as shown in Fig. 2, the box-shaped green flour (1 ') has the advantage of providing a wider vegetation growth area than the circular green flour (symbol 1 in Fig. 1), while being inserted into the rock surface. Need an auxiliary device.

At this time, as an auxiliary device that can be used, the rectangular pedestal 13 to be inserted into the rock while supporting the box-shaped greening powder 1 'is designed and used, and the size thereof is not particularly limited as long as it can support the greening powder 1'. Do not.

In addition to the box-shaped greening powder 1 ', the pedestal 13 is preferably separately provided with a drain 11' and a draining portion 15 for smooth drainage of the greening powder. At this time, it is sufficient to provide 1 to 5 drainage portions 15 to 10 mm in diameter. The stopper can selectively use PVC, plastic, rubber, wood, polymer material, etc. according to the box greening.

In addition, it is advisable to design and insert a separator 14 for drainage and moisture storage of the box-shaped greening powder 1 '. Such a separating plate 14 is provided for the purpose of separating the cultured soil to be filled in the greening powder 1 'from the bottom of the greening powder 1' to help drainage and water storage, so that the insertion position is the greening powder 1 '. It is inserted between the bottom of the soil and the culture soil, and a height of about 10 to 20 mm is sufficient.

In this case, the separator 14 may be made of PVC, plastic, rubber, or the like, which does not have a risk of corrosion on water. In order to assist the drainage of the greening powder in the separation plate 14, it is preferable to separately install the drain port 11 'and the drain part 15 as in the case of the pedestal 13 described above.

In addition, it is preferable to disperse the pressure by providing four to eight leg portions 16 at the bottom of the separating plate 14 to disperse the pressure of the soil weight. The main purpose of the legs to be attached to the separation plate 14 is the function of adjusting the dispersion of the culture soil pressure, securing the moisture of the greening powder and the height of the culture soil. According to these three purposes, the thickness and width are designed and manufactured in the same manner as the thickness of the separator, and the height of the leg 16, which is most affected by the load, is made not to exceed 1/3 of the total height of the greening. This is because as the height of the leg increases, it is easy to secure moisture, but on the contrary, the growth place becomes smaller, which may affect the growth of the plant. The leg 16 may also use a material such as PVC, plastic, rubber, etc., which does not have a risk of corrosion on moisture.

In addition, the position of the drain 11 'of the greening powder 1' also varies according to the height of the separator. In other words, the drain hole to be placed on the back of the box-shaped greening powder is changed depending on the height of the legs of the separator plate, and at least half of the drain hole is closed by the separator plate to obtain the effect of preventing excessive drainage of water.

That is, the drain 11 'of the green box 1' box is formed in a circular shape, but the shape in which the actual water is drained by the separator 14 is shown in a semicircle shape. Therefore, it is possible to minimize the soil lost to the drain by the rapid supply of moisture in the rainy season and to prevent the loss of culture soil to the upper part of the greening by the excessive saturation of moisture in the box by discharging the water to the drain.

In order to create a greening base within the greening area (1,1 '), a mixture of cultured soil and greenery species (vines and native plants, etc.) is mixed to properly record rock slopes and stony development areas early in nature. You can mix tree species.

In other words, simply put the greening powder (1,1 ') containing the cultured soil and green tree species in the perforated hole on the rock slope, the greening method is completed and the greening is made early.

At this time, it is recommended to use at least one species selected from the group consisting of exotic herbaceous, native herbaceous, and wooden herbaceous species, especially Tall fescue ( Festuca arundinacea ) , and Perennial ryegrass ( Lolium Perennial herbaceous, selected from the group consisting of perennial herbs ( Digitaria sanguinalis ) and gujeolcho ( Chrysanthemum zawadskii )) and at least one native herb selected from the group consisting of Chassis ( Lespedeza) cyrtobotrya ) and cypress ( Indigofera pseudo - made of a woody two kinds of herbaceous in four species of tinctoria), the seeding rate, taking into account the planting area of nokhwabun and disseminated to the appropriate amount in each of the vegetation by 10 ribs, and vine plants of ivy, wisteria, masakjul It is more preferable to plant honeysuckle, honeysuckle, jacaranda, hawthorn, and the like.

In addition, the culture soil and vines and native plants are most preferably inserted into the perforated by putting the microorganisms and seeding by mixing the vines and native plants in the culture soil.

On the other hand, the greening powder (1,1 ') has one feature suitable for the lubrication and moisture retention of the vegetation by the cultured soil prepared as a form suitable for insertion into the perforated rock slopes.

The culture soil is not limited to this, but the mixed soil soil and general soil mixed with the surrounding soil soil, where the rock slope slope greening method is applied using perforation. The culture soil may be selected from one or more of four culture soils depending on when and where the method is applied and the seed used.

The culture soil is preferably composed of one or more selected from the forest soil (Humus soil of forest), normal soil (Merchantable general soils), mixed soil (Mixed soil) and topsoil of forest, the weight of each culture soil Considering the volume of the vegetation growth portion of the used within the range of 600g to 1500g, the weight ratio of the forest erosion soil, normal soil, forest surface soil is most preferably about 2: 1: 2.5.

 Furthermore, the mixing ratio of mixed soils is also preferably mixed by mixing forest soils, general soils, and forest surface soils in a weight ratio of 2: 1: 2.5 within 200g to 500g.

That is, as an example, forest corrosion soil is about 1200g, general soil is about 600g, mixed soil is about 1100g (400g + 200g + 500g), forest surface soil may be used by about 1500g each.

In the preparation of cultured soil of the present invention, the degradation of non-nitrogen organics, nitrification, the generation of safe aggregates, growth promoter secretion, and antibiotic secretion lower the density of pathogens in soil, and secrete various biologically active substances to grow underground parts of plants. Soil microorganisms are added to promote this. Specifically, the soil microbial agent is Trichoderma Hagianum harzianum ), which is intended to help the growth of plants underground by reducing the density of pathogens in the soil by antibiotic secretion.

The vegetation and growing part (10,10 ') of the greening powder (1) is projected out of the rock slopes, so the culture soil in the greening powder (1,1') is lost due to rainfall and runoff, so the mulching treatment material on the greening powder treated with microorganisms For example, the mulching treatment may be performed using various materials such as jute or cornet (see FIGS. 3B-3E). The effect of such mulching material is to prevent the evaporation of moisture in the soil by direct sunlight, prevent weeds, to prevent the erosion caused by soil formation.

Hereinafter, the present invention will be described in detail through examples. This is only an embodiment of the present invention, the present invention is not limited thereto.

[ Example ]

A. Preparation of Greening Powder

As shown in Figure 1, the greening powder is a circular green powder (1) of 260mm in total length of the PVC material (10) vegetation growth is projected out of the rock surface to 125mm in length, 65mm in height. The total height of the circular greening powder (1) is 100mm and the remaining parts except the 125mm where vegetation grows are inserted into the rock surface, and there are three 10mm drainage openings 11 at the bottom to drain the water introduced from the vegetation growth part. It was.

In addition, as shown in Figure 1a, two horizontal grooves (12) formed in the back portion of the greening to form a V-shaped to help the absorption of moisture and the development of the root system.

In addition, as shown in Fig. 2, the vegetation-growing part 10 of the box-shaped greening powder 1 made of ocher material was a rectangular part of 318mm * 218mm and its height was 80mm. A rectangular pedestal of 400mm * 80mm * 50mm was designed and used as a PVC material as the pedestal 13 to support the box-shaped greening powder 1 and to be inserted into the rock.

In addition, a divider plate made of PVC material having 10-20 mm in height for drainage and moisture storage of the box-shaped greening powder 1 and three drain holes 15 having a diameter of 8 mm for draining the box-shaped greening powder 1 14) was inserted between the bottom of the greening powder (1) and the culture soil.

Furthermore, four leg portions 16 were installed at the bottom of the separation plate 14 to disperse the pressure of the culture soil to be filled in the greening powder 1 '. At this time, the leg 16 was designed using a plastic 20mm size.

B. Preparation of Cultured Soil

A green cloth (1) made of PVC material was used to absorb the excess soil moisture contained in the perforated soil.

Vegetation and growth unit 10 was protruded out of the rock slopes to facilitate the supply of light and moisture, the remaining portion was inserted into the perforation. One of the three absorbent openings underneath is in the perimeter of the inclined plane and two in the perforation. The schematic drawing of such greening is shown in Figs. 1A to 1C.

The mulching process was performed using the jute as a mulching treatment material on the obtained circular greening powder 1, and the figure is shown to FIG. 3B-3E.

C. Preparation of Cultured Soil

Cultured soil used in the present invention was composed of forest soil (Humus soil of forest), normal soil (Merchantable general soils), mixed soil (Mixed soil) and topsoil of forest (Topsoil of forest).

For reference, the cultured soils used for greening bases of general specialty lands and artificial grounds use relatively light soils in consideration of the load of greening bases. However, in the case of rock slopes, the vegetation growth base composition is given priority over the load of culture soil, so it may be an efficient way to use the forest soil if it is possible to extract from the surrounding forest.

In particular, considering the total volume of greening powder, 10,808㎣, the weight of the cultured soil was used 1200g of forest etched soil, 600g of ordinary soil, 1100g of mixed soil, 1500g of forest surface soil. The mixing ratio of the mixed soil was 2: 1: 2.5 using 1/3 of the weight of each cultured soil, based on 200g, which is 1/3 of the weight of normal clay.

The weight of each culture soil used in the mixed soil was mixed with forest soil, normal soil, forest surface soil 400g, 200g, 500g respectively.

Type and weight of culture soil Soil media type Weight (g) / pot Forest Corrosion Soil (H.s) 1200 Plain topsoil (M.g.s) 600 Mixed Earth (M.s) 1100 Forest Surface Soil (T.s) 1500

The water content of each culture soil was 14.5% for forest soil (Hs), 51% for general soil (Mgs), 17.4% for mixed soil (Ms), and 8% for forest surface soil (Ts), and the acidity (pH) was 4.88 for forest soil. There were differences between forest humus and forest surface soils as topsoil 5.05, mixed soil 4.93, and forest surface soil. The organic matter content (%) was the highest with 10.14% of forest soils and 0.72% of forest surface soils.

Substituent cations and cation substitution capacities are higher than those of other treated soils. It is believed that the adsorbing and retaining of fertilizer components is higher than that of other culture soils, so that even when a large amount of fertilizer is given, transient over-absorption is suppressed.

conclusion

Previously used green powder was suspended on the railing of the bridge and used to promote urban scenery. However, the use of green powder as used in the present invention for the surface greening of the mined rock wall or rock slope has been confirmed. Nonetheless, the greening method using post-perforated greening powder presented in the present invention on a rock slope is a new technique, and the experiment has proved a very good growth effect.

According to the present invention, by localizing various environmentally friendly green materials (vegetation zones and vegetation panels, etc.) that have been dependent on imports, it is possible to exert enormous import substitution effects, such as saving of technology transfer costs, and general rust soil and seed spraying method, anchored pinch ridge wire mesh Compared to the slope recording method, which covers vegetation-based materials, the cost and labor are reduced, and the labor force can be distributed, resulting in low cost and high efficiency.
