The present invention relates to a planting planter structure for improving the lateral environment of an urban area. More specifically, the present invention relates to a low-impact development type lateral environment planting structure having a purifying filter.

In the urban area, the surface of the earth is composed mainly of buildings and roads, and the rainwater is not penetrated into the ground, so that the vitality of the soil is gradually being lost, and accordingly, the natural ecological environment is gradually disappearing. In urban areas, which are mostly impervious areas, the urban environment has been created to cope with the flood prevention rather than the soil vitality or natural ecological environment. Thus, the urban environment was created by the rapid drainage of rainwater through the sewer pipe of the road to the outskirts of the city, rivers or rivers.

However, in the conventional urban environment, the underground penetration of the rainwater is reduced, the function of the water source of the soil is lost, and the groundwater resources are exhausted. Since rainwater must be discharged at one time, The increase of outflow causes rather flood, and the increase of air pollution and non-point pollution of roads in the city due to the increase of traffic volume lead to pollution of the river by flowing into the river together with rainfall, It is evident that adverse effects occur.

In addition, the rainwater can not penetrate into the ground in urban areas, and the ecosystem of the soil is destroyed, which leads to the destruction of the urban ecosystem. The food chain base is reduced and the vegetation structure is simplified. Furthermore, And eventually lead to disaster.

The planting planter structure of the present invention is a low-impact type planting structure of a low-impact type that collects rainwater in the city side and recovers the collected rainwater in the ground underground to restore a natural ecological environment.

In order to solve the problem of the prior art that raises rainwater to groundwater without storing the rainwater or causes rainwater overflowing in the case of intensive rainfall or rainfall to flow to the river or river through the sewer to cause soil ecological problem Developed.

The present invention relates to a method and apparatus for preventing groundwater resources from being depleted by treating surface runoff occurring in the horizontal and vertical portions of an urban area by treating the contaminated initial stormwater simultaneously with the collection of the surface runoff from the permeable planting planter, And it has the advantage of reducing the capacity of the sewer pipe due to the decrease of the surface runoff, thereby being able to play a role of flood control in the case of concentrated rainfall or persistent rainfall. The structure of the present invention is intended to be installed in advance in the lower part of the avenue and planting the roadside tree thereon.

As shown in FIG. 1, the rainwater collected through the steel grating 200 passes through the upper space A and is stored in the lower storage space B. In the present invention, the upper space A is filled with a filter medium to purify rainwater collected, and a purifying filter 170 is installed between the upper space A and the steel grating 200.

FIG. 2 is a schematic plan view of a purge filter 170 of two (A, B) embodiments according to the present invention. Such a planar configuration of the purifying filter 170 can be easily implemented by a person having ordinary skill in the art to which the present invention belongs. The purifying filter 170 has a sponge-like structure to facilitate permeability while adsorbing harmful components such as waste oil on the road, calcium chloride, and noxious bacteria. Since the purifying filter 170 is installed under the steel grating 200, the purifying filter 170 can be cut to a desired size and used. The purifying filter preferably has a thickness of about 1 to 5 cm, but is not limited thereto. The purifying filter 170 can be used again after a certain period of time if the pollution becomes severe or after a cleaning process. Replacement and cleaning cycles can be carried out flexibly according to the degree of contamination.

The rainwater primarily filtered at the purifying filter (170) is purified again while passing through the filter medium filled in the upper space (A). As a result, the purified rainwater is stored in the lower storage space (B). The filter medium for filling the upper space (A) is formed of a fine sand layer, a coarse sand layer, a small gravel layer, and a thick gravel layer from the lowermost part. The filter material for filling the upper space A can be easily carried out by a person having ordinary skill in the art to which the present invention belongs.

The lateral environment planting structure of the first embodiment according to the present invention comprises four outer walls 10, 20, 30, 40, four inner walls 50, 60, 70, 80, a lower center wall 90, And a bottom member (97), wherein an upper space (A) is formed at an upper side by the outer wall, an inner wall and an intermediate horizontal member, and the upper wall A storage space B is formed on the lower side by the member, and a soil space C is formed on the inner side by the inner wall.

After the trees are planted in the soil space (C), the upper space (A) is covered with the upper cover (200). The upper cover 200 is conventionally used for protecting the roadside water, and is preferably made of steel.

The upper space A forms a separate and unified space except for the soil space C formed by the inner walls 50, 60, 70 and 80.

The soil space C comprises the outer wall 10, 20, 30, 40 and the inner walls 50, 60, 70, 70 on the intermediate horizontal member 95 so as to penetrate the soil around the outside of the planting plant structure 100. [ 80 and a lower center hole 90 is formed to penetrate the soil below the structure and a lower center hole 91 is formed.

Soil space (C) is a space where trees are planted, and the roots of trees can be extended. The roots can be extended to the soil outside the structure through the outer wall upper holes 11, 21, 31, 41 between the outer walls 10, 20, 30, 40 and the inner walls 50, And the roots can extend to the soil under the structure through the lower central hole 91.

The inner wall holes 51, 61, 71 and 81 may be selectively formed in the inner walls 50, 60, 70 and 80 and the storage spaces B may be formed in the lower portions of the outer walls 10, The outer wall lower holes 12, 22, 32, and 42 may be selectively formed to penetrate the outer soil.

As shown in FIG. 3 to FIG. 5, the rainwater stored in the storage space B by connecting the storage space B and the soil space C is supplied to the roots of the trees gradually planted over a long period of time One or more climate change adaptive multi-purpose filters (151, 152) installed to supply the rainwater stored in the soil space (C) for the purpose of supplying rainwater.

The multi-purpose filters 151 and 152 supply the rainwater stored in the soil space C by the capillary phenomenon into the soil space C so as to be supplied to the roots of the planted trees gradually over a long period of time. The multi-purpose filters 151 and 152 can be made of various materials such as fibers and fabrics. Any materials capable of supplying water from the storage space (B) into the soil space (C) by capillary action are all usable.

The intermediate horizontal member 95 must have permeability because the purified rainwater in the upper space A has to descend into the soil space C. [ The intermediate horizontal member 95 also naturally has a function as a filtration layer.

The rainwater stored in the storage space (B) seeps into the lower ground through the bottom member (97) and joins the groundwater, thereby restoring the ecosystem in the ground. The bottom member 97 should also be water permeable like the middle horizontal member 95. The rainwater stored in the storage space B may be impregnated into the outer soil of the side portion through the outer wall lower holes 12, 22, 32, and 42 formed at the lower portions of the outer walls 10, 20, 30 and 40.

Since the planting plant structure of the present invention is almost semi-permanently used, it is preferable to be made of a synthetic resin such as plastic. The size and shape of the structure can be variously modified depending on the environment of the place to be installed, the plant species, and the like, and such modification can be easily performed by a person having ordinary skill in the art to which the present invention belongs.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
