Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a pavement structure using a prefabricated storage block having rainwater storage function,

The present invention relates to a ground pavement structure using a prefabricated storage block, and more particularly, to a pavement block structure in which a pavement block and a walkway are packed in a sidewalk block, the water circulation function and the soil function of the ground are improved, The present invention relates to a ground pavement structure using a prefabricated storage block having a storm storage function capable of improving the ecological effect and capability of the groundwater pavement.

As economic development and industrialization and urbanization progressed, impervious pavement structures such as concrete and asphalt pavements increased, and the natural rain water circulation system in the city was destroyed. As a result, the amount of rainwater infiltrated into the ground decreased, Natural and ecological functions are damaged, and environmental damage such as land and water quality, as well as natural disasters such as climate change, urban flood, and so on, cause huge damage repeatedly.

Especially, in Korea, where most of the annual precipitation is concentrated in summer, when most of the rainwater is not penetrated into the ground during the heavy rainfall, it flows into the sewer at one time and exceeds the allowable amount of stormwater. Urban inundation that leads to flooding is frequent. On the other hand, there are many problems such as river runoff, bad smell, lowered groundwater conservation, and depletion of water due to only one fifth of the annual rainfall in the fresh water season (from November to April) have. Therefore, when the amount of rainfall is large, the infiltration and storage of stormwater are prevented to prevent flood damage, and when the amount of rainfall is small, measures to prevent drought damage are required to release stormwater storm.

Urban ecological problems such as urban climate change and biodiversity reduction are closely related with the impervious area (packing area) of the city, and the increase of impervious area is the main cause of urban desertification, Urban floods, which are the recent annual event, flood roads and sidewalks due to the backflow of sewage, as the drainage facility fails to function if a large amount of rainfall close to or exceeding the capacity of the existing drainage facility is concentrated in a short period of time have.

In order to solve such a problem, there has been developed a technology for an excellent infiltration and storage tank that temporarily stores rainwater and adjusts the flow rate to the sewage. For example, in Patent No. 582121, " This paper proposes a concrete storage block that can be stacked in multiple stages. However, since it is made of concrete, it is difficult to carry and transport because it is heavy because it is heavy, it is difficult to construct due to the heavy equipment required in the landfill installation, and there is a problem that the cost is low in terms of cost and construction period such as concrete casting and curing. And reinforcing materials such as reinforcing steel must be used. There is a problem of water pollution due to the toxicity of the concrete itself.

Patent No. 1020718 entitled "Soil-permeable pavement structure using geocell for geotechnical reinforcement and hollow fiber reinforced permeable block" is a system for installing a ground layer, a gravel layer and a sand layer sequentially installed with a drainage structure, And a permeable block is installed on the upper surface of the geocell. However, since the above-mentioned pavement structure is formed by draining the drainage structure along the longitudinal direction only in a part of the ground layer, if the storm is poured or a lot of storm is introduced into the ground where the pitcher block is installed, There is no problem.

Therefore, the reservoir block and soil pavement, which can sustain and improve the natural circulation function (evapotranspiration function, fine dust adsorption function, stormwater permeability and storage function, soil function, etc.) for natural disaster reduction and ecological problem of city Structure and new packaging method are urgently required. In order to solve the above-mentioned problems, the applicant of the present invention has developed the patent No. 1435373 entitled " Hollow-shaped Superior Reservoir Block ", and found various improvements that were not anticipated during construction, We are constantly researching and developing blocks.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a rainfall prevention apparatus, a rainfall prevention apparatus, To improve the ecological effect of the natural circulation system and to improve the water circulation function and to improve the ecological effect and ability of the natural circulation system and when rainfall or heavy rainfall increase suddenly, the rainwater can be prevented from flowing into the sewer, The present invention is to provide a ground packing structure using a prefabricated storage block having a rainwater storing function.

A ground packing structure using a prefabricated storage block having a rainwater storage function according to the present invention is characterized in that a filling block is installed on an upper part of a hearth (ground surface), and the filling blocks are arranged at equal intervals in four directions, A first compartment of a shape both open downward and closed on its side by a first partition; And a second compartment disposed between the first compartments and open both above and below and having a side closed by a second partition and a first partition, Wherein the first compartment has a rectangular shape and a hexahedron shape having the same height, wherein a groove is formed in an upper end portion of an upper part of the first partition wall outwardly arranged outwardly of the first compartment, And the recesses and the protrusions are formed in a shape corresponding to each other. When the reservoir block is assembled by connecting the recesses, the recesses formed in the adjacent storage blocks The two adjacent surfaces of which one end portions are in contact with each other are the surfaces on which the groove is formed, Wherein the first and second compartments are integrally formed on the lower surface of the first and second compartments so that permeable water is formed, 2 The compartment is filled with gravel or crushed stone.

Preferably, the first filling block is located at the top of the hearth and is filled with gravel or crushed stone; A reservoir block located above the first filling block; And a second filling block located above the storage block and having a permeable sheet at the bottom and filled with gravel or crushed stone. The storage block and the first and second filling blocks have the same structure.

Preferably, the filling block is located at the top of the hearth (the ground) and has gravel or crushed stone in it; A reservoir block located above the filling block and having a permeable sheet laid underneath; And a sidewall block disposed above the storage block, wherein the storage block and the filling block have the same structure.

The ground packing structure using the prefabricated reservoir block according to the present invention having the above-described features is characterized in that rainwater is stored in the reservoir block itself and then slowly flows through the reservoir block, Reduce the amount of backwater and flood damage, improve the water circulation function to the ground, and improve the ecological effect and ability of the natural circulation system. In addition, since the reservoir block of the present invention is installed at the lower part of the sidewalk block, rainwater can be temporarily stored in the event of heavy rain or heavy rainfall, so that it can function not only in a sidewalk, a square or a park, but also as a water- .

Also, since the storage block is assembled, it is assembled according to the area of the installation area to form one large flat plate, so that the sidewalk can be partially depressed, excessive settlement and uneven settlement can be prevented, Since the lower part of the sidewalk block is flattened so as not to have irregularities or steps in the block, an accident that the sidewalk falls on the sidewalk block due to the absence of the sidewalk block can be prevented.

On the other hand, the first and second compartments of the storage block of the present invention are filled with gravel, crushed stone, slag, or grass, and the storage block itself is used as a floor surface of a parking lot, park, It is possible.

FIGS. 7 to 11 are cross-sectional views illustrating various embodiments of a ground packaging structure using a storage block according to the present invention.

The most important technical features of the prefabricated storage block and the ground packing structure using the prefabricated storage block according to the present invention are that a storage block made of waste plastic, waste vinyl, or waste tire is installed at the bottom of the pedestal block, This is because the rainfall can be prevented from flowing into the sewer at the same time even if heavy rainfall is poured by allowing the rainfall to slowly infiltrate or flow through the time lag.

In the specification of the present invention, the "sidewalk block" is a non-adhesive and adhesive-type packaging or partial packaging such as an interlocking (interlocking) block, a stonewall, and the like in consideration of road conditions, And blocks used to package all roads, sidewalks, plazas, and parks, etc., as a general term.

Since the storage block 10 of the present invention is manufactured by extrusion molding, it can be manufactured by changing the thickness and size as needed, and is light and easy to install, which makes it possible to work without an expert. Since the block itself has a wide width and adjacent blocks are joined to each other to be integrally formed into a large plate shape, the load acting on the upper portion is dispersed to improve the ground resistance performance of the ground layer against the load, Excessive settlement and uneven settlement of the ground can be prevented. Also, since it is easy to assemble and disassemble, it can be worked in a short time even when excavation work is performed for water supply of the sidewalk, open space, communication, electricity, or when the damaged block is replaced.

The storage block of the present invention is installed at a lower portion of a sidewalk block installed on a road, a sidewalk, a square or a park, and serves to temporarily store storm water. The material is made of waste plastic, waste plastics or waste tire It is light and recycles waste resources, so it is environmentally friendly and can reduce waste disposal costs. The storage block 10 has a polygonal shape as a whole, but a square is most preferable and not necessarily a shape in consideration of ease of installation. The storage block 10 has a first compartment 11 and a second compartment 12 may be integrally molded into a certain standard so that the entire planar shape has a rectangular shape and the same height and can be used by being fastened to each other.

The first compartment 13 is circular in plan, but it is not necessarily limited to a circular shape, but it can be formed in any shape, such as a polygon or a specific shape. The first compartments 13 are arranged at regular intervals in four directions, both open upward and downward, and have a side closed by the first partition 11 (see FIG. 1).

The second compartment 14 is disposed between the first compartment 13 and is open at both the upper and lower sides and the side is closed by the second partition 12 and the first partition 11 (See Fig. 1). Since the second compartment 14 is disposed between the first compartment 13, the shape of the second compartment 14 varies according to the shape of the first compartment 13.

Fig. 1 shows the first embodiment. The first and second compartments 13 and 14, which are opened vertically, store rainwater that has leaked when the space between the first compartment 13 and the second compartment 14 is in a rainy state. By delaying or suppressing rainwater runoff when rainfall occurs due to drainage or spillage, it prevents flood damage by preventing it from flowing into the sewer at one time, and improves water circulation function to the ground.

The overall planar shape of the storage block 10 is a polygonal plate shape and the first compartment 13 protrudes into the outer side of the polygonal shape or is located at a position inward (corresponding to the protruding shape) The upper end of the first partition 11 is formed with a protrusion 112 and a groove 113 which correspond to each other in the vertical direction and are fastened to each other to form a large plate. So that the storage block is not opened between the storage blocks even if the storage block is pushed by a sharp object at the top. Here, the polygonal shape is not a straight polygonal shape but a part of the first barrier rib 11 or the second barrier rib 12 may be formed as a protrusion or a concave shape (embedded shape) in the outer side, . As can be seen from Fig. 1, two adjoining surfaces, one end of which is in contact with one another, are the one on which the groove 113 is formed, and two opposite surfaces of the surface on which the groove 113 is formed are the projections 112 Is formed.

2 shows a second embodiment of the present invention. In the first embodiment, the first compartment 13 or the second compartment 14 adjacent to the upper part of the first partition 11 and the second partition 12, So as to form a groove serving as a channel. For example, the upper part of the second bank 12 is formed with a row of grooves 121 communicating with the adjacent second compartment 14, and the upper part of the first bank 11 A communication hole 111 communicating with the second compartment 14 is formed. The communicating hole 111 and the tongue groove 121 may be formed in a concave groove shape at the upper ends of the first partition 11 and the second partition 12 and a through hole may be formed at the upper portion to communicate between the compartments Or may be formed in plural numbers.

3 shows the third embodiment. In the first embodiment or the second embodiment, the upper and lower surfaces of the first compartment 13 and the second compartment 14 are closed and the rainwater flows into the closed plate It is formed a through hole which can be discharged. For example, a first barrier plate 15, which closes the upper part of the opened first compartment 13, is integrally formed, and the second partition 14, which closes the lower part of the opened second compartment 14, The first blocking plate 15 and the second blocking plate 16 are formed with a first through hole 151 and a second through hole 161 respectively. The shape of the first through hole 151 and the second through hole 161 need not be particularly limited.

The means for fastening the storage blocks 10 to each other can have various shapes. The storage portion 112 and the groove 113 as shown in FIGS. 1 and 2 may be used as the fastening means, 3 and the projection 112 'and the groove 113' may be formed as shown in FIG. As long as the fastening means are formed in mutually corresponding shapes and can be fastened to each other, there is no single pipe of any shape, and the formed position is not necessarily limited to the first partition 11 and is formed in the second partition 12 It may be formed on both the first barrier rib 11 and the second barrier rib 12, as long as it does not matter.

4 shows the fourth embodiment. In the first embodiment or the second embodiment, the lower surface of the first compartment 13 and the second compartment 14 is closed and the rainwater can flow out to the closed plate. And a through hole is formed. For example, a plate-shaped blocking member 17 is integrally formed on the lower surface of the storage block 10 to close the lower portions of the first and second compartments 13 and 14 that are open (opened) The penetrating hole 171 is formed in the blocking member 17 for each of the first and second compartments 13 and 14. [ Of course, the shape and number of the pitcher hole 171 need not be limited.

Fig. 5 shows the fifth embodiment. In the fourth embodiment, the blocking member 18 is not a plate member but a rod-like member. Since it is rod-shaped, there is no need for a water hole for drainage, and the shape of the rod need not be limited either.

6 is a view showing a state in which the storage block 10 is installed on the bottom surface and then the space of the first and second compartments 13 and 14 is filled with a filling material 20 such as gravel, (10) itself can be utilized as a floor surface of a parking lot, a park, a square, and the like, thereby realizing an environment-friendly floor surface.
