Description

Method for constructing block for L type road-side having a function of rainwater penetration}

The present invention relates to a construction method of the L-shaped side block having a stormwater penetration function, in particular in most road areas to penetrate the rainwater discharged to the ground through the L-shaped sidewall to reduce the peak runoff and to improve the groundwater It relates to a construction method of a block having a good penetration function to be able to contribute.

Recently, as urbanization progressed rapidly due to the increase of population, improvement of living standard and industrialization, impervious surface increased. As the impervious surface increased, runoff increased due to the failure of rainwater to penetrate underground, resulting in various environmental problems in terms of increased flood damage, river water pollution, and water depletion.

Particularly, most of the paved roads are provided with a road drainage system in the form of an L-shaped side opening 10. A conventional L-shaped side opening 10 is formed between the road 11 and the sidewalk boundary stone 14, Drainage layer 15 is made of concrete so that rainwater flows at the same height, and rainwater does not penetrate into the underground, and flows into the river as it is through rainwater pipes (not shown) buried underground along the drainage layer 15.

Therefore, the necessity of rainwater penetration facilities for contributing to the improvement of groundwater by improving the conventional road surface drainage facilities in a form that can be stormwater is emphasized.

The present invention has been invented to meet the above necessity. In most of the paved road areas, the rainwater that has been drained from the road through the L-shaped openings installed at the edges of the roads penetrates into the ground to reduce peak runoff and increase groundwater. The purpose is to provide a construction method of blocks to contribute to the

The present invention for achieving such an object,

Fixing a sidewalk road boundary stone at an edge of a sidewalk in consideration of a place where a permeable block having a plurality of permeable holes is to be installed;

Break through the lower part where the permeable block is to be settled and crush the ground, and then form a second gravel layer of 5-15 cm high gravel from the lower part, and the first small gravel 5-10 cm high on the upper part of the second gravel layer Forming a gravel layer, and forming a sand layer of sand having a height of 3-8 cm; And,

Constructing the permeable layer to be exposed on the ground by fitting the seam of the permeable block formed on the top of the sand layer, and then filling the loam into the permeable hole of the permeable block, and seeding the plant seeds on the filled loam.

According to the present invention, while inducing smooth drainage of rainwater, the rainwater flows into the underground to reduce the flow rate flowing into the rainwater pipe and increase the moisture in the soil.

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

Figure 2 of the accompanying drawings is a cross-sectional view for showing the L-shaped side opening of the road drainage system according to the present invention, Figure 3 is a plan view showing an embodiment of the road surface drainage shown in Figure 2, Figure 4 is 2 is a plan view illustrating another embodiment of the road drainage system illustrated in FIG. 2.

The construction method of the block having the excellent penetration function according to the present invention is a step of the road 110 and a predetermined height in consideration of the place where the permeable block 152 having a plurality of permeable holes 151 is installed as shown in FIG. Fixing the sidewalk road boundary stone 140 through the concrete pouring on the road 110 side edge of the sidewalk 120 installed with 130.

When the sidewalk road boundary stone 140 is fixed, the bottom of the permeable block 152 is to be settled to a certain depth and evenly ground the ground. After the ground is evenly formed, a second gravel layer 158 made of large gravel having a diameter greater than or equal to a predetermined height is formed at a height of 5-15 cm, and the first gravel layer 156 made of gravel having a small diameter on the top of the second gravel layer 158. ) Spread evenly to 5-10cm thickness.

On the top of the first and second gravel layers 156 and 158, a water permeable layer 159 is formed of a sand layer 154 evenly sanded 3-8 cm thick, and a plurality of permeable holes 151 on the sand layer 154. The transparent block 152 molded to have a structure is constructed so that the upper part is exposed to the surface by fitting the seam as shown in FIGS. 2 and 3.

After constructing the permeable block 152, the loam is filled in the permeable hole 151 of the permeable block 152, and the flocked loam has a root system having a root system that grows well in a dry place due to manpower. Sowing seeds of Festuca ovina and Poa compressa.

As such, after constructing the block having the rainwater penetration function according to the present invention, which can be applied to most road sections, the runoff water due to rainwater may be formed through the sand layer 154 and the first and the first through the permeable holes 151 of the permeable block 152. It penetrates underground through the second gravel layers 156 and 158, which not only reduces peak outflow but also contributes to the uplift of groundwater.

In addition, the city's water circulation system can be improved, contributing to the maintenance and development of the urban soil ecosystem, and controlling the temperature by absorbing some of the radiant heat generated in the city in the summer. In addition, by introducing the vegetation through appropriate seed sowing to the permeable block 152, it is possible to create an ecological environment that can be inhabited and moved in association with the green space in the city, including street trees.

In other words, the present method improves the existing drainage method of the road drainage treatment with the L-shaped side opening to install a permeable block 152 having a permeable hole 151 on the ground on which the permeable layer 159 is installed to induce smooth drainage of rainwater. At the same time, it penetrates the rainwater underground, reducing the flow rate into the rainwater pipe and increasing the moisture in the soil.

As described above, the present invention improves the environmental problems such as flood damage, river water pollution and water resource depletion through the reduction of peak runoff and the increase of groundwater by penetrating the rainwater that has been treated by road drainage underground, and through proper seeding By introducing vegetation, it is effective to create an ecological environment that can be inhabited and moved in connection with green spaces in urban areas including street trees.

Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited thereto and may be improved or modified by those skilled in the art within the scope of the technical idea of the present invention.
