Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a drainage structure for a grass planting,

The present invention relates to a drainage structure for lawn planting and a method of constructing the same, and more particularly, to a drainage structure for lawn planting and a method of constructing the drainage structure for lawn planting, To a drainage structure to be drained smoothly and a method of construction thereof.

In recent years, a lot of greenery construction work has been carried out to prevent soil loss by planting lawns on playgrounds, parks, or sloping mountain slopes, which were recently constructed with sand, to prevent dust from flying.

These green zones are formed to have a high gradient in the central part for drainage in the case of rainy weather and to have a slight gradient in the periphery, and a drainage hole is formed in the perimeter to make the rainwater flow, or the lower soil layer in which the grass is planted, Make sure that the bottom is well permeated.

However, when rainfall continues and the rate of permeation to the soil layer is slowed down and the amount of water is increased, a waterway is formed in the lower soil layer and the soil is lost.

This soil loss can cause a problem that the surface of the lawn material layer becomes uneven due to the puddle due to the sinking of the grass planting part, or a cavity is formed in the soil layer below the lawn, thus causing a safety accident.

In addition, if the water in the depressed pit or the cavity is rotten, odor is generated and bacteria and mosquito larvae are propagated, which is harmful to hygiene.

One of the ways to solve the above problems is to install a lot of drainage holes. However, the drainage hole usually needs to be constructed by pouring concrete or steel bar using a formwork, or constructing a stainless steel pipe or a reinforced concrete pipe to the soil layer. There is a problem in that it is not easy to construct as much as necessary in a wide range of playgrounds, parks, mountain slopes, and the like, rather than a fixed building or a green area surrounding the structure.

A drainage structure structure of a playground according to the prior art is disclosed in Korean Patent Registration No. 10-1309827 (a playground drainage structure using a line and a construction method thereof). This technique relates to a playground drainage structure and a construction method that can provide elasticity and smooth drainage while maintaining the hardness of the athletic field index as it is in the prior art. A plurality of pores of a size of about 1 mm; A drainage trough embedded in the drainage layer and having a plurality of water holes formed on an outer circumferential surface thereof and a drainage passage formed therein; A lower cushion layer laminated on the drainage layer and the drainage troughs and made of a water permeable and elastic material to provide an elastic force; And a surface layer stacked on the upper portion of the lower cushion layer and exposed to the outside, wherein the drain trough is buried along the line at a lower portion of the line, and the upper surface of the drain trough is located at the same height as the upper surface of the drain layer And water that is buried in the drainage layer and reaches the drainage layer flows into the drainage trench through the water hole formed on the drainage trench.

However, in order to construct the drainage trench, the conventional art is constructed in such a manner that the embankment layer of the lower surface of the ground is drained over a larger area than the drainage trench, and after the drainage trench is installed, In this case, due to the interference of the installed drainage trough, it is impossible to compaction by the pressure applied at the time of initial compaction, so that the water seeped in the case of rain can be condensed. There is a structural problem.

In addition, the above-mentioned prior art is a technique in which drainage can be made only through a part of a green area, and it is still not a technique for preventing drainage of a wide green space and soil loss, It is inevitable to develop a technology capable of solving drainage and soil loss problems at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a perspective view showing a drainage structure according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of a drainage structure according to an embodiment of the present invention, FIG. 3 is a perspective view of a drainage plate according to an embodiment of the present invention FIG. 4 is a view illustrating an example of a method of coupling a drainage plate constituting a drainage structure according to an embodiment of the present invention, FIG. 5 is a view illustrating an example of a drainage structure constructed in a playground according to an embodiment of the present invention, FIG. 6 is a view illustrating an example in which a grass planting material layer is applied to a drainage structure according to an embodiment of the present invention. FIG. 7 is a cross-sectional view of a drainage structure including a rubble drainage pipe according to another embodiment of the present invention. FIG. 2 is a view showing a state in which a grass planting layer is applied to a plant.

As shown in the drawing, the present invention mainly includes a plurality of protruding support portions 11 and drainage portions 11 to prevent the rainwater from being permeated into the lower soil layer 6 while supporting the load of the grass planting layer 5, 12) is formed; A cushioning material (2) installed on the drainage plate to provide a buffering force to the grassing material layer; And a fastening member (3) inserted through the cushioning material to be coupled between the drain pan and the cushioning member and inserted and fixed to the projecting support.

The drainage structure having such a structure is continuously installed on a soil layer such as a playground, a roof, or a mountain slope. When the natural or artificial grass material layer is then applied to the upper part of the drainage structure, the greenery composition is completed. In addition, it is common to apply silica sand or filler on the surface of the grassy material layer after application. In addition, the grass planting layer is constructed such that drainage holes are formed at regular intervals to be permeated downward.

The drain pan, the cushioning material and the fastening member may be made of a synthetic resin material or a metal material, but injection molding of a synthetic resin material is preferable in terms of corrosion resistance or molding process. Specifically, it is preferable that the drain plate is made of a hard synthetic resin material because its main purpose is a durable drainage structure, and it is preferable that the buffer material is made of a soft synthetic resin material so that buffering force and stretchability are good and the fastening member has durability, It is preferable to be made of a hard synthetic resin material.

The drainage structure can charge the rubble 7 for supporting the load at the drainage portion between the drainage plate and the buffer material. In this case, in order to delay the drainage flow due to the decrease in the volume of the drainage portion formed by the protrusion support portion, It is possible to arrange the drainage pipes (4) of the drainage pipes (4) between the buried rubble in the drainage portions at regular intervals to assist drainage. Of course, the rubble may be formed of a rubble layer covering the upper part of the drainage plate as well as the drainage part if necessary.

A plurality of protruding supports 11 protruding from the upper surface of the drain plate 1 are arranged in the left-right direction. The shape of the protruding support according to one embodiment has a truncated conical shape in which the sectional area decreases from the lower part to the upper part.

The inside of the protruding support portion is constituted by a space portion whose lower part is opened, and is intertwined with a soil layer below the drainage plate. The space between the height formed by the protruding support portion protruding in the upward direction and the protruding support portion formed at a predetermined distance from the adjacent protruding support portion constitutes the drainage portion 12. Therefore, when the rainwater flows in the upward direction, the water flows to a drain pipe (not shown) provided at an arbitrary point through the drainage unit. This drainage portion is not formed so as to have a specific flow path and flows naturally in any direction as long as it is inclined or where there is a drop of rainwater. Therefore, the drain pipe can be conveniently installed without having to define a separate drainage channel.

Such a drainage plate is provided on the soil layer to prevent the inflow of rainwater, thereby preventing the soil layer located at the lower part from being leaked, thereby preventing the sinking of the grass material layer and the co-occurrence of the lower soil layer.

At the center of the upper surface of the protruding support part 11, a fastening film part 111 is formed in the form of a thin film so that the fastening member 3 passing through the cushioning material 2 is fastened thereto. Although the fastening portion 111 is normally covered with a thin film, when the fastening member is positioned on the upper portion of the protruding support portion in order to engage with the cushioning member at a position of any protruding support portion selected at the time of construction, The fastening portion is broken and a hole is formed and the fastening member passes through the fastening portion of the protruding support portion while the fastening member passes through the fastening portion of the protruding support portion while the insertion portion is contracted to enter the inner space portion of the protruding support portion.

In addition, a support piece 13 protruding in a lattice form is formed on the lower surface of the drain plate to prevent slippage when the drain plate provided on the soil layer is in surface contact, and to prevent the shape of the drain plate from being twisted.

The support piece shown in accordance with one embodiment is configured to have about four projecting supports 11 per individual grid area, the number of which does not limit the present invention, .

In one embodiment, the drain plate 1 may be constructed by connecting a square plate having a square shape as a unit drain plate through a connecting portion 14 formed on each of four circumferential surfaces of a neighboring unit drain plate, have.

At this time, two of the connection portions formed on the circumference of the drain plate are composed of the lower connection portion 141, and the remaining two are formed to have different heights so as to form the upper connection portion 142. Further, each of the lower or upper connection portions is configured to be connected to each other. When the lower connection portion 141 and the upper connection portion 142, which correspond to each other between the neighboring drain plates, are vertically positioned, a compression protrusion is formed in an unillustrated compression groove formed in a shape corresponding to either the upper portion or the lower portion, They may be squeezed together and fastened to each other to integrate them. However, the present invention is not limited to the upper and lower coupling schemes exemplified in this embodiment, and any one of known clamping methods may be used as long as the upper and lower coupling can be integrated.

The cushioning material 2 is formed with a plurality of fastening holes 21 arranged in the transverse direction corresponding to the fastening film portions 111 formed on the respective projecting supports 11 of the drainage plate 1. [ The fastening holes are perforated so that the upper fastening portion of the protruding support portion located at the lower portion can be identified.

The size of the cushioning material and the drain plate may be the same as the square plane size, or may be of different size or square shape. Also, when the cushioning material and the drain plate of the same size are fastened together, they may be arranged at the same position in the up and down direction, or may be arranged so that they are staggered from each other and deviated from each other. However, in order to facilitate the fastening of the fastening members in any arrangement, the fastening holes located at the upper and lower sides should be arranged on the same axis or on adjacent axes.

The cushioning material 2 is a porous water-permeable material and can sufficiently store the rainwater or discharge it to the lower drainage plate. If more rainwater flows in, the drainage rate may be slowed down. And the drain holes 22 are arranged at regular intervals between the drain holes 22. The drain hole 22 is formed in a pierced state so that the introduced rainwater is drained to the drain portion 12 located directly below. And are arranged so as to be positioned one by one in the central portion of the four fastening holes arranged in a rectangular shape in one embodiment. However, the present invention is not limited to such an arrangement, and only one or more of them may be formed in a space in which no fastening hole is formed.

In addition, the cushioning material (2) is formed with an elongated groove (23) to prevent deformation or breakage of the cushioning material (2) due to different thermal expansions at the time of expansion and contraction due to a temperature difference due to climate change in Korea, which has four distinct seasons. The expansion grooves are formed by grooves formed in the inner direction of the cushioning material in the form of a lattice in which a plurality of the cushioning materials are arranged in the longitudinal and transverse directions. The cushioning material is provided on at least one of the upper surface and the lower surface of the cushioning material so as to be elongated or contracted, .

It is preferable that the above-mentioned elongated and contractible grooves are symmetrical to the upper and lower surfaces of the cushioning material because they can exhibit a uniform stretching force or shrinking force during the stretching and shrinking movement.

The fastening member 3 passes through a plurality of fastening holes 21 formed in a cushioning material when the drainage plate 1 and the cushioning material 2 are fixed and is fastened to the center of the upper surface of the projecting support portion 11 formed on the drainage plate 1. [ And penetrates and joins the membrane portion 111.

The upper portion of the fastening member 3 is constituted by a stopper 31 for closing the fastening hole 21 of the cushioning material 2 and the lower portion of the stopper is constituted by a cylindrical insertion portion 32 passing through the fastening hole and fastening film portion . The insertion portion 32 is formed with one or more cutout grooves 321 cut vertically so as to have an elastic force upon contraction or expansion. The cutout groove 321 of the insertion portion 321, A hooking protrusion 322 is formed obliquely from the lower end to the upper end along the circumference.

When the fastening member having the above structure is selected, a protruding support portion at an arbitrary position out of the protruding support portions formed on the drain plate positioned below the fastening hole of the cushioning member is selected, It is lowered while breaking the membrane-shaped fastening portion. At this time, the insertion portion gradually contracts due to the outer diameter of the inclined latching jaw formed in the circumferential direction of the insertion portion, and when the latching jaw passes the fastening portion, it is elastically expanded again while being contacted and supported by the inner surface of the upper portion of the projecting support portion.

The perforated drain pipe (4) is made of a flexible synthetic resin material, and a plurality of holes (41) are formed along the periphery so that rainwater flows into the inside and drained. In addition, the through-hole drain pipe may be provided with a non-woven fabric or the like wrapped around the circumference as needed to prevent the inflow of soil or foreign matter. Of course, it is of course possible to use a hole drain pipe without wrapping the periphery of the nonwoven fabric.

Further, the shape or diameter of the through-hole pipe is not limited to the shape and size of the illustrated embodiment, and may be modified into various shapes and sizes not illustrated, provided that it is capable of inflow and outflow of rainwater.

By providing a plurality of such drainage pipes, it is possible to reliably drain water by assisting drainage of drainage of the drainage plate filled with rubble.

FIG. 8 is an exemplary view showing an anchor provided with an anchor in a state where a grass planting layer is installed on a drainage structure according to an embodiment of the present invention. FIG. 9 is a cross- And an anchor is installed in a state in which a grass planting layer is applied to the drainage structure.

As shown in the drawings, the present invention can be applied to a natural or artificial grass material layer 5 stacked on a buffer material, and a 'C' shaped anchor 8 for reinforcing a fixing force if necessary. The anchor is configured to penetrate the drainage structure from the upper part to the lower part in the grass planting layer and to be inserted and fixed in the lower soil layer. At this time, according to the embodiment, the rubble and the drainage pipe may pass through the drainage part filled with water.

Although the anchor is not used, a separate fixing member is not necessary because of the inherent weight of the natural or artificial grass material layer that is rolled up while being rolled into a roll shape. However, when an anchor of a thin thickness is additionally installed, And the drainage structure can be increased.

The installed anchors do not interfere with the walking of the person who is working on the lawn while the protruded portion is not large, so that even when a local external force is applied, the grass material layer is prevented from being thrown and the grass material layer is prevented from being damaged.

The anchor may be installed through any part of the drainage structure at the time of construction, but it is preferable to touch the installation site of the drainage structure located at the lower part of the grass planting layer to facilitate the construction of the drainage structure so as to penetrate the support hole formed in the upper surface of the protrusion support part .

10 is a flowchart illustrating a construction procedure according to an embodiment of the present invention. The construction steps of the drainage structure will be described below.

First, the step of preparing the drainage structure according to the present invention is provided. (S10)

Thereafter, the compaction and flattening step is performed on the soil layer or the general soil layer, which is constructed by multi-layered strata of different materials on a playground, a roof or a mountain slope, etc. (S20)

In the step S20, known compaction means such as a roller device or a vibratory compaction device may be used. The reason for flattening the soil layer is to even out the construction surface of the drainage structure and the grass planting layer to be constructed in the subsequent step.

Thereafter, the drainage plates 1 constituting the drainage structure according to the present invention are continuously connected by an area required for greenery composition. (S30)

The thermal connection method between the unit drain plates 1 in the step S30 is performed by placing the lower connection part 141 or the upper connection part 142 formed on the circumference of the drain plate so as to overlap with the upper connection part 142 or the lower connection part 141 of the neighboring drainage plate And then tighten it.

If necessary, the upper part of the drain pan is pressed after the drain pan is installed, so that the support pieces 13 located at the lower part of the drain pan are inserted into the soil layer and the soil layer enters the inner side of the protruding support part to be filled, have.

If necessary, a step of arranging the drainage pipes 4 at predetermined intervals in the drainage unit 12 formed in the drainage plate 1 after the drainage pipe is installed, and filling the rubble 7 thereon may be added.

The fastening hole 21 formed in the cushioning material 2 is positioned on the upper surface of the protruding support portion 11 and the upper surface of the protruding support portion 11 formed on the drainage plate 1. [ So as to be visible.

Thereafter, the plurality of fastening members 3 are pressed at the position of the optional fastening hole 21 of the cushioning material 2 to penetrate the fastening film portion 111 of the projecting support portion 11 formed on the drain plate 1, 2 and the drain plate 1. (S50)

In this process, the insertion portion 32 of the fastening member 3 descends while breaking the fastening film portion 111 in the form of a thin film formed at the central portion of the upper surface of the projecting support portion 11. When the fastener passes through the fastening portion, the insertion portion receives a contraction force due to the outer diameter of the slanting hook 322 formed in the circumferential direction thereof. Since the plurality of cutout grooves 321 are formed in the insertion portion 32, When the engaging jaw 322 passes the fastening film portion, it is resiliently resiliently engaged with the inner surface of the upper portion of the protruding support portion 11 while being supported. At this time, the stopper 31 constituting the upper part of the fastening member 3 blocks the fastening hole 21.

Thereafter, the natural or artificial grass material layer 5 is applied to the upper surface of the cushioning material 2. (S60) When the above step is completed, the green material composition is completed.

In addition, it may have a step of spraying silica sand or a filler (e.g., rubber chips, rice hulls, loess) on the surface of the lawn planting material layer, if necessary. By using these steps, the silica sand or the elastic filler not only protects the grass layer from being damaged but also provides a feeling of cushioning or an ordinary soil layer so that people are not injured during exercise or walking.

When the rain is lowered after completion of the construction of the grass planting layer, the rainwater is impregnated to the lower part through drainage holes (not shown) formed at regular intervals in the grass planting layer, and then the rainwater is permeated through the drainage plate and the cushioning material according to the present invention A drainage is made.

If necessary, an anchor passing through from the grass planting layer 5 to the lower soil layer may be installed to directly bond the grass planting material layer and the drainage structure to integrate them.
