Description

[0001] The present invention relates to a sidewalk block for providing excellent drainage and soil safety,

The present invention relates to a sidewalk block having one or more drains for discharging rainwater. More specifically, the present invention relates to a sidewalk block for preventing foreign matter from rainwater discharged through a drainage port, .

Generally, sidewalks, parks, and plazas are packed with ascon or concrete, or they are constructed with various types of concrete sidewalk blocks. Here, the sidewalk block is dense due to the nature of the material, and rainwater or air can not pass through it. The sidewalk block is sandwiched between the air and the ground, so that the air can not pass through between the air and the ground.

In existing pavement blocks, rainwater flows through the gap between the sidewalk block and the sidewalk block, and only a small amount of the pile flows into the ground, and most of the storm is accumulated on the sidewalk block. There is a problem that the storm on the sidewalk block flows along the surface gradient of the sidewalk block, causing inconvenience to the walk. Moreover, rainwater is not absorbed into the ground even in areas with large green spaces such as parks, plazas, and high-water areas, and flows directly into the sewer pipe along the sidewalk block. As a result, the surface of the ground is getting dry and it becomes difficult to grow microorganisms and plants living in the ground There is also a problem of depletion of groundwater. In addition, since the air permeability of the surface and the atmosphere is lowered, the heat absorption of the ground surface and the release of heat generated from the ground surface are blocked, thereby adversely affecting the atmospheric circulation and increasing the atmospheric temperature.

Therefore, in order to solve this problem, one or more drainage holes are formed in the sidewalk pavement of the unpaved floor to discharge the rainwater to the ground. These pavement blocks not only lead to safe walking with the discharge of rainwater, but also to protect the environment by ventilation to the ground. However, due to the drainage hole formed in the sidewalk block, there is a serious problem causing an ankle fracture as well as obstructing the walking due to the slip of the slippery during walking. Furthermore, there is a problem that the discharge of rainwater is interrupted by the inflow of various foreign substances such as gravel and toilet paper into the drain hole.

Therefore, in order to solve such a problem, Korean Patent Registration No. 10-1283094 (the name of the invention: a pitcher press block constituted by a filter pipe) is proposed. That is, the filter pipe is inserted into the drain hole (through hole) of the sidewalk block to prevent the shedding of the high heel or the clogging of the foreign object. However, when the amount of rainwater is high or the rainfall time is long such as rainfall or rainfall, the rainwater that is drained continuously falls on the ground, and the ground is damaged.

Of course, as a solution to this problem, Korean Patent Registration No. 10-0435535 (name of invention: press block with desalination function) and Korean Registered Utility Model No. 20-0432219 And a sidewalk block having a sidewall. In other words, a separate space is provided to prevent rainwater from falling directly on the ground, thereby preventing drainage along with drainage. However, in the case of the former, a block having a desalination function and a block having a drainage function are stacked, resulting in a waste of air due to manufacturing and construction. In the latter case, one block is configured to have both fresh water and drainage functions. However, since a one-shot mold (molding sand) is inevitably used to manufacture a core structure having both fresh water and drainage, There is a problem.

In order to solve such a problem, Korean Patent Registration No. 10-0951712 (the name of the invention: a sidewalk block provided with a porous filter) and Korean Patent Laid-Open Publication No. 10-2016-0136877 Sidewalk block). In other words, although there is no direct description that it is possible to prevent subsidence, it is possible to prevent sedimentation by slowing the flow rate of the drainage water by constituting the filter with a porous material such as char, activated charcoal, elvan stone powder or ceramic powder . However, there is another problem of rainwater accumulation on the sidewalk block due to the difficulty of smooth drainage due to the decrease of the flow velocity.

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

The present invention relates to a sidewalk block for guiding safe walking on the ground on which a pedestrian travels, and comprises a block 10, a filtration tube 20, a protection tube 30, and fastening means as shown in Figs. 1 and 2 It is a walk block.

The press block according to the present invention is constructed with a filtration pipe 20 for inducing smooth drainage and safe walking, and a protection pipe 30 for preventing settlement of the ground from being installed on the block 10, A connecting means for separating the filtration pipe 20 and the protection pipe 30 is provided so as to reduce the total number of steps required for manufacturing and installation and to improve maintenance and repair.

First, the block 10 according to the present invention is a square stone formed into a predetermined size so as to be installed on the ground on which the pedestrian travels. The stone is mixed with cement, an admixture, a reinforcing agent, a stone, and a cleaning agent. It is recommended to use activated charcoal or charcoal as a substance that can purify polluted water.

1 and 2, at least one drainage hole 11 is formed which has a width and a thickness for packing at least a ground surface and discharges rainwater falling on the surface. Here, the drainage hole 11 is formed in a shape of either a circle or a square, and is formed to be open at one side.

The filtration tube 20 according to the present invention prevents foreign objects in the rainwater from leaking or sticking, while preventing the heel or stick of the shoe from falling off or coming in contact with the water. As shown in FIGS. 1 and 2, Or injection-molded into a rectangular shape. The filtration tube 20 is formed with a plurality of filtration holes 21 at the center thereof for blocking foreign matter mixed with rainwater in the longitudinal direction.

3, the filtration hole 21 may be formed in a circular or square shape, and the filtration hole 21 may be formed to gradually expand the area from the upper portion to the lower portion into which the rainwater flows. Therefore, even if the foreign matter flows into the filtration hole 21, the foreign matter can be quickly passed without being caught inside. Above all, it does not interfere with the flow of water, so we can expect smooth drainage.

At this time, the upper surface of the filtration tube 20 is preferably formed as a conical or dome-shaped downwardly inclined downward from the center so as to prevent accumulation of foreign matter filtered from the filtration hole 21. [ That is, the foreign matter filtered on the upper surface of the filtration tube 20 is not continuously deposited but flows outward due to its own weight. Therefore, clogging of the filtration holes 21 can be prevented without removing the foreign substances.

The protection pipe 30 according to the present invention protects the ground by controlling the flow velocity and the flow rate of the rainwater to be discharged. The protection pipe 30 has a circular or square shape capable of being removed from the drain hole 11 as shown in FIGS. 1 and 2 Injection molding.

The protection pipe 30 is installed in the lower part of the filtration pipe 20 so as to communicate with the filtration hole 21 and has a fresh water space 31 for controlling the flow rate and the flow rate of the rainwater flowing into the filtration hole 21 And at least one water passage hole 35 for discharging the rainwater in the fresh water space 31 to the outside is formed on the side surface. That is, the rainwater falling down into the filtration hole 21 can prevent direct contact with the obstructed surface of the fresh water space 31, and can safely protect the ground by lowering the flow rate and flow rate of the rainwater discharged.

Here, the water holes 35 may be formed laterally at a position spaced apart from the bottom of the fresh water space 31 by a predetermined height. In other words, by keeping the water filled in the fresh water space 31 by the height of the water passage hole 35, the collision of the falling rain is reduced, and the summer ground and the heat of the block 10 are cooled.

At this time, the channel holes 35 can be formed on the same line or at different positions. That is, when the water passage holes 35 are positioned on the same line as shown in Figs. 1 to 3, the rainwater is filled in the fresh water space 31 and quickly discharged to the outside as soon as a predetermined water level is reached. On the other hand, if they are positioned at regular intervals every equal height as shown in FIG. 4, they are gradually discharged even if a predetermined water level is reached. Therefore, it can be applied to have suitable water holes 35 according to the climate and the condition of the ground.

Lastly, the fastening means according to the present invention selectively removes the filtration tube 20 and the protection tube 30, and is formed at a position where the filtration tube 20 and the protection tube 30 are opposed to each other. That is, the fastening means allows the filtration tube 20 and the protection tube 30 to be detached and the filtration hole 21 and the water passage holes 31 to be maintained.

For example, the fastening means includes a fastening protrusion 41 capable of bending inward and outward at a portion where the filtration tube 20 and the protection tube 30 are engaged with each other as shown in Figs. 2 and 3, The engaging groove 42 can be formed. That is, when the fastening protrusions 41 are fitted into the fastening grooves 42 and the filtration tube 20 and the protection tube 30 are mounted and, on the contrary, the fastening protrusions 41 fitted in the fastening grooves 42 are pushed inward, The pipe 20 and the protection pipe 30 can be detached. Although the fastening protrusion 41 is formed in the filtration tube 20 and the fastening groove 42 is formed in the protection tube 30, it is also possible to form the fastening protrusion 41 in the opposite direction.

Of course, the fastening means may be formed of a male screw 43 and a female screw 44, respectively, for guiding the fastening of the filtration tube 20 and the protective tube 30 to each other, as shown in FIG. Since the male screw 43 and the female screw 44 are mounted to each other by the rotation of the filtration tube 20 and the protective pipe 30, it is preferable to apply the rounded shape to the hexagonal shape shown in FIG.

The press block according to the present invention may be formed integrally with the filter tube 20 and the protective tube 30 as shown in FIG. It is preferable that the filtration body 25 provided with the filtration hole 21 is rotatably divided from the filtration tube 20 so that the filtration hole 21 and the water passage hole 35 can be maintained as required.

A locking projection 45 and an engagement groove 46 are formed on the inner and outer surfaces of the filtration tube 20 and the filtration body 25, respectively. That is, when the engaging protrusion 45 protruding from the outer surface of the filtration body 25 is vertically inserted into the bending recess 46 recessed in the inner surface of the filtration tube 20 and then horizontally rotated, the fitting is completed . On the contrary, of course, the filtration body 25 can be detached from the filtration tube 20.

At this time, it is preferable that a control tube 26 for selectively opening and closing the channel holes 35 is integrally formed at the lower portion of the filter body 25. This filter body 25 further protrudes a handle 25a for inducing the rotation of the upper portion and the adjustment tube 26 is formed with one or more adjustment holes 26a which selectively coincide with the water passage holes 35 as the rotation do.

In other words, the discharge rate of rainwater should be considered according to the climatic conditions and the ground conditions at the place to be constructed as described above. Of course, it is only necessary to mount the water channel holes 35 that satisfy these conditions. However, there is a disadvantage in that it is not possible to quickly respond to changing climate and environment, and it must be manufactured for various water holes 35.

Therefore, even after the installation, the water holes 35 can be selectively opened and closed according to various variable conditions by rotating the filter body 25 using the handle 25a exposed on the upper surface, thereby controlling the discharge speed of the rainwater . Here, it is preferable that the upper surface of the filtration tube 20 is integrally formed with a notifier 20a indicating the opening and closing direction of the channel hole 35 and the degree of opening and closing according to the rotation of the filtration body 25.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
