Description

Sidewalk Blocks for Plant Growth

The present invention relates to a sidewalk block capable of growing plants that are capable of growing plants in existing sidewalks and parking lots made of concrete blocks or asphalt to promote ecological stability and provide a human-friendly environment.

Existing parking lot or sidewalk paved with concrete or asphalt will give a porosity function for plant growth, and it will be equipped with refreshing sidewalk function and ecological side by allowing rain to easily penetrate to the ground through the porous of blocks. As an ecological block to be able to do so, in particular, the construction of the golf course (walkway) by providing a comfortable path for the cart or golfer while at the same time enabling the growth of grass to be friendly to the surrounding environment.

Conventional parking lots and sidewalks are paved with ascon or concrete, or constructed with concrete sidewalk blocks made of molds, thus forming a structure in which plants cannot grow.

In addition, in the case of the asphalt paved sidewalks such as rain or rain during the rain will create a bad environment for walking, and the temperature of the sidewalk surface is excessively increased in the summer.

In addition, in the case of the moving path of the golf course is constructed in a similar way, such as tire mats or artificial turf, which does not fit with the surrounding environment gives a sense of heterogeneity, and in the rainy weather to create an uncomfortable environment of the moving path.

The present invention was devised to solve the problems of the prior art as described above, in order to form a porous vegetation base using a certain size coarse aggregate and cement, water, admixture to produce a porous ecological coverage block, more plants In order to improve the growth of the planting hole of a certain size of the block was formed.

In addition, the present invention was to maintain the water / cement ratio of 30% or less in order to maintain the strength of the sidewalk block, using a crushed stone or gravel of a certain size to secure the porosity.

In addition, it is important to ensure that the roots of the plants pass through the pores of the sidewalk block and settle in the soil base under the sidewalk (back) as soon as possible, thus promoting fertilizer and root growth in the pores and voids of the sidewalk block. Fill with a water-soluble polymer mixed with a substance that assists (for example, plant hormones of oxins), and a mixture of soil (field soil) and vermiculite. Fill two-thirds of the height of the sidewalk block with the filling, then mix the seeds of the plants with the filling and fill the sidewalk block again and cover it with a thickness of about 1-5 cm above the sidewalk block.

Hereinafter, preferred embodiments of the present invention will be described in detail.

Example 1

13-25㎜ crushed stone 1,500㎏ / ㎡, blast furnace cement (Korea Furnace Cement Co., Ltd.) 260㎏ / ㎡, water 50㎏ / ㎡, high performance water reducing agent (Dongnam Corporation: high performance water reducing agent, high strength type fluidizing agent, Fastener, adhesive mixing) Each material was prepared at a mixing ratio of 5.2 kg / m 2, mixed well in a mixer, and then put into a conventional concrete block mold and compressed by a constant hydraulic pressure while applying vibration, as shown in FIG. 1. The planting work 12 of was molded into the concrete sidewalk block 10 which was perforated (penetrated). At this time, the ratio of water and cement (weight ratio) was set to 20%. The molded concrete sidewalk block 10 was cured at high temperature and wet for 8 hours in a curing room, and again cured in air in a wet state to produce a concrete block.

After curing the sidewalk block (10) manufactured as described above sufficiently evenly to the floor (ground) of the area to be constructed, and then moistened with a good moisturizing soil (for example, soil, loess) and fined about 0.5 After covering with a thickness of -1cm, the sidewalk block 10 is constructed so that the back side of the sidewalk block is sufficiently in close contact with the ground so that the capillary tube can be connected.

After constructing the sidewalk block 10 as described above, and then sprinkled on the sidewalk block 10 is filled with a mixture of soil (field soil) and vermiculite, superabsorbent polymer, etc., and then sprinkled with water on the sidewalk block (10). S) was filled between the gap of the sidewalk block 10 and the planting hole (12).

Next, when the filling is about two-thirds of the sidewalk block 10, the seeds (grass) are mixed with the filling to the height of the sidewalk block 10, and the soil and vermiculite mixture is then added again. Covered to a thickness of cm, water was sufficiently watered.

After 5 days of construction, the grass seed started germinating, and after 30 days, the surface was covered with green color. Since the growth point of the grass (生長 존재) is lower than the surface of the sidewalk block 10, it is possible to survive even if people step on or step on the vehicle. However, in the case of the parking lot, when the vehicle was parked continuously during the daytime, the growth tended to be poor due to the lack of sunlight, but it did not have a great influence on the growth unless the conditions were to continue to be shaded.

As a result of examining the growth state of the roots by cutting the sidewalk block 10 after 8 weeks of sowing, it was observed that the grass roots were grown to the lower side (back side) of the sidewalk block along the pores of the sidewalk block. This is the result of the roots of the grass is safely guided to the lower soil of the sidewalk block 10 along the moisture of the moisturizer filling the space between the block pores.

Since the roots are not deeply grown after the roots are mounted on the soil below the sidewalk block 10, most of the roots remain in the middle of the sidewalk block, so that the planting hole 12 as shown in FIG. 1 is shown. By piercing it was observed that many roots gathered in the soil filled in this area.

In the above, the inner diameter of the planting hole 12 preferably forms 1-20 cm. When the inner diameter of the planting hole 12 is 1 cm or less, the stiffness of the sidewalk block 10 is advantageous, but the soil filled in this portion is reduced, which hinders the growth of the plant. It is made, but relatively decrease the rigidity of the sidewalk block (10).

In addition, it is preferable that the porosity of the sidewalk block 10 (referring to the porosity excluding the space of planting holes) is 20-40%. When the porosity is 20% or less, the stiffness of the sidewalk block 10 is improved, but the growth of the plant roots is reduced. When the porosity is more than 40%, a good environment is created for the growth of the plant roots, but the stiffness of the sidewalk block 10 is relatively high. Will be lowered.

Example 2

5-13mm crushed stone 1,500㎏ / ㎡, blast furnace cement (Korea Furnace Cement Co., Ltd.) 280㎏ / ㎡, water 56㎏ / ㎡, high performance water reducing agent (Southeast Corporation): high performance water reducing agent, high strength fluidizing agent, 2) Prepare each material at a mixing ratio of 5.2 kg / m2, and mix well in a mixer, and then put the material in a conventional concrete block mold and compress it with constant hydraulic pressure while applying vibration as shown in FIG. A number of planting holes 22 formed a concrete sidewalk block 20 that was perforated (penetrated). At this time, the ratio of water and cement (weight ratio) was set to 20%. The molded concrete block was cured at high temperature for 8 hours in a curing room, and was cured again in a wet state by air curing to prepare a concrete sidewalk block 20.

After sufficiently curing the sidewalk block 20 manufactured as described above, the floor surface (floor) of the area to be constructed is sufficiently even, and then moistened with good moisturizing soil (eg, soil, loess), and then fined about 0.5 After covering with a thickness of -1 cm, the construction of the sidewalk block 20 is to ensure that the back surface of the sidewalk block is in close contact with the ground enough to connect the capillary tube.

After constructing the sidewalk block 20 as described above, and then sprinkled on the sidewalk block 20, the filling material mixed with the soil (field soil) and vermiculite, superabsorbent polymer, and the like taken on the sidewalk block 20, and then water Sprinkle the filling was filled between the gap of the sidewalk block 20 and the planting hole (22).

Next, when the filling is about two-thirds of the sidewalk block 20, the seeds (grass) are mixed with the filling to the height of the sidewalk block, and the soil and vermiculite mixture is added to a thickness of about 1 cm. After covering, water was sufficiently watered.

The sidewalk block 20 prepared in Example 2 had a porosity of about 20-30%, and the pore size was smaller than that of Example 1 using coarse aggregate, but the tissue permeability did not show a great difference in water permeability. As it becomes more compact, it can be seen that the strength of the sidewalk block 20 is improved.

The growth of the grass also showed a slight difference. In the case of Example 1, the grass grows evenly between the aggregate gaps other than the planting area, so that the entire sidewalk block is uniformly covered, whereas in the case of Example 2, the planting hole 22 is mainly used. The grass was growing in the center.

However, over time, it was observed that the grass roots in the planting plant settled stably by extending between the aggregate gaps around the planting plant.

In the above, the inner diameter of the planting hole 22 preferably forms 1-20 cm. When the inner diameter of the planting hole 22 is 1 cm or less, the stiffness of the sidewalk block 20 is advantageous, but the soil filled in this portion is reduced, which hinders the growth of the plant. It is made, but the stiffness of the sidewalk block 20 is relatively reduced.

In addition, it is preferable that the porosity of the sidewalk block 20 (referring to the porosity excluding the space of planting holes) is 20-40%. When the porosity is 20% or less, the stiffness of the sidewalk block 20 is improved but the growth of the plant roots is reduced. When the porosity is more than 40%, a good environment is created for the growth of the plant roots, but the stiffness of the sidewalk block 20 is relatively high. Will be lowered.

Example 3

Example 3 manufactured the sidewalk block in the same manner as in Example 2, but instead of using coarse aggregate, sand and stone powder (cement) were used to eliminate the voids of the sidewalk block 30 itself, and the planting hole 32 was completely removed. The perforated sidewalk block 30 is produced.

At this time, the strength and density of the sidewalk block 30 could be seen to increase to some extent.

However, the growth of plants (grass) was limited to planters (32), and the roots of grass showed a total dependence of nutrients and moisture on the soil layers below planters. In the early days, lawns looked like spots around planters, but as the grasses grew, they connected and covered the entire footpath green.

In the above, the inner diameter of the planting hole 32 preferably forms 0.5-10 cm. When the inner diameter of the planting hole 32 is 0.5 cm or less, it is advantageous for the rigidity of the sidewalk block 30, but the amount of fillings filled in this portion is reduced to inhibit plant growth. To make but relatively decrease the rigidity of the sidewalk block (30).

In addition, the porosity occupied by the planting hole 32 for the entire sidewalk block 30 is preferably 5-40%. When the porosity is 5% or less, the stiffness of the sidewalk block 30 is improved, but the growth of plant roots is reduced. When the porosity is 40% or more, a good environment is created for plant root growth, but the stiffness of the sidewalk block 30 is relatively high. Will be lowered.

Example 4

Embodiment 4 manufactures the sidewalk block in the same combination as in the first embodiment, except that the planting block formed in the sidewalk block 40 is not completely perforated, but as shown in FIGS. 4 and 5. ) To form a planting groove 42 made of grooves (pips) to a depth of about 1 / 2-2 / 3 to the thickness, so that the soil material and seeds easily settled in the planting groove (42), By lowering the thickness of the lower block of the planting groove 42 as compared to the thickness of the sidewalk block 40 is to facilitate the plant (P) vegetation settlement around this portion.

The inner diameter of the planting groove 50 and the porosity of the sidewalk block 40 is configured in the same manner as in the first embodiment.

Meanwhile, the sidewalk blocks shown in Examples 1 to 4 are just examples, and the shape and shape of the sidewalk blocks can be manufactured in various ways to produce the sidewalk blocks of the present invention.

In the drawings, reference numeral a denotes a crushed stone, and b denotes a cement.

As described above, by providing the sidewalk block of the present invention to a parking lot or sidewalk paved in the form of a block of concrete, plant growth is possible, and at the same time, rain is easily drained to the ground so that it can be refreshed with the sidewalk function and the natural environment. The ecological side will have the effect.
