The present disclosure relates to a sidewalk-roadway combined block system having improved rainwater permeability with a gap. In more detail, the present disclosure relates to a sidewalk-roadway combined block system having improved rainwater permeability with a gap, the block system being able to manage permeation and storage of rainwater and being advantageous in construction to which a biotope area ratio is applied because it is possible to secure water permeation sustainability by not only passing rainwater through a gap, which is structurally formed, but also improving the efficiency of discharging a mixture of granules and powders.
Recently, cement roads or paved roads are increased due to rapid progression of urbanization, so impervious surfaces are increased and it has been reported that over 73% of urbanized regions are impervious surfaces.
As such impervious surfaces increase, rainwater flows to sidewalks and causes inundation when it locally rains very heavily due to a climatic change, or water shortage and a heat island phenomenon due to high heat of the ground are generated during a drought.
Porous permeable blocks for roads have been proposed in the related art to solve these problems, but It has been known that their water permeation function remarkably decreases within six months after construction because their pores are clogged with dirt, so it is recommended to “perform vacuum high-pressure suction cleaning at least two time a year” under the maintenance references.
Further, according to existing permeable blocks, since the supporting force between the blocks is low, the supporting force is increased by filling the masonry joints with sand, etc., but sands fill even the pores of the blocks for water permeation in this process, so not only does the permeability rapidly decrease, but also weeds grow between the blocks and deteriorate the appearance. Accordingly, there is also a problem that it is required to remove such weeds.
For example, in “a block for paving, a paving structure using same, and a construction method thereof” of Korean Patent No. 10-1227275, there has been proposed a technique that can pass downward discharge water in a large area on or around a road using a high-performance permeable paving surface block having an excellent water permeation function and can enable rainwater permeating through an upper paved surface to permeate into and under the ground by stacking deep blocks under a paved surface.
Further, a block for a road that improves rainwater permeation sustainability by improving an efficiency of discharging a mixture of granules and powders, a paving structure using same, and a construction method thereof have been disclosed in Korean Patent Application Publication No. 10-2016-0089918, but there is a problem that since the structure is complicated, massive construction is difficult due to an S-shaped fitting connection portion with another block and it is difficult to replace a damaged portion.
Recently, in accordance with ┌Natural Environment Conservation Act┐, object businesses, the selection methods, etc. for a biotope area ratio have been integrally prescribed in the notice, ‘Joint gap-permeable pavement’ was newly established. Further, the permeability test was prescribed to follow only the indoor constant-head permeability coefficient test method (KS F 4419) that can test only existing permeable blocks themselves, but a site permeation amount test method (KS F 2394) and a site permeability test method (ASTM C 1701) are also included to be able to test various permeable blocks. Accordingly, it finally became possible to realize commercialization of ‘joint gap-permeable pavement’ that is advantageous in securing a biotope area in a city and improving permeability.
The inventor(s) has succeeded in developing a sidewalk-roadway combined block system with a gap that not only passes rainwater through a gap at an assembled joint, but also has excellent sustainability of permeability and is simply constructed by improve an efficiency of discharging a mixture of granules and powders while studying and developing gap with a gap for a road that is an object of a biotope area ratio for many years.

The above and other objectives, features and other advantages of the present disclosure will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawings, in which:
Preferred embodiments of the present disclosure will be described hereafter in detail with reference to the accompanying drawings. In the following description of the present disclosure, detailed descriptions of well-known functions or configurations relating to the present disclosure will not be provided when it is determined that they may unnecessarily obscure the point of the present disclosure.
First, the present disclosure provides a sidewalk combined block system with a gap that is advantageous in application of a biotope area ratio because base blocks are simply constructed in an assembly type, and not only can pass rainwater through a gap structurally formed when they are combined, but also can improve the efficiency of discharging a mixture of granules and powders, thereby securing water permeation sustainability.
In the present disclosure, a sidewalk-roadway includes blocks for sidewalk that are laid on a sidewalk on which pedestrians go through and blocks for vehicles on which vehicles can go through.
In the present disclosure, unit assembly blocks 10 are simply constructed in an assembly type, and not only can pass rainwater through a gap structurally formed when they are combined, but also can improve the efficiency of discharging a mixture of granules and powders. Further, the unit assembly blocks 10 are constructed on the floor of a parking lot, a park, a walk, etc., and water is temporarily stored in a gap space between the blocks and then slowly permeates into the ground, whereby the unit assembly locks can be used to prevent inundation of a passage due to local rain or melting of collecting snow and to prevent pores from being clogged that is the defect of existing permeable blocks.
In the combined block system with a gap according to an embodiment of the present disclosure, as shown in
In the gap portion in the present disclosure, a front portion 31 is formed with the lower portion cut in an inverse triangular shape, gap maintenance ends 32s are formed to be spaced apart from each other at the center region of the front portion 31 and each formed such that the area of the upper end is smaller than the area of the lower end in the vertical length, and rain guides 33 start from a lower end at a predetermined gap from the top and are inclined at both sides so that rainwater slides. When a combined block system is constructed, as in
Meanwhile, referring to
Referring to
In this case, the unit assembly block 10 may be characterized by being made of a concrete or synthetic resin material. Porous permeable blocks that are used in the related art have a defect that the permeability of the blocks themselves at the early stage of construction is difficult to be maintained for a long period of time due to clogging by a mixture and the blocks are easily broken due to reduction of bending strength by the pores in the blocks themselves. However, according to the present disclosure, pores of a block itself are removed, bending strength is increased by manufacturing the block through a compression method, and instead, rainwater is passed through the gap between the blocks and rainwater or mixtures such as sand or dust dropping down on the top of the block are also send downward through the gap. In this case, the lower portion is made wider than the upper portion to prevent the gap portion from being clogged with a mixture.
The unit assembly blocks 10 can be manufactured in various types in accordance with the areas and situations in which they are constructed, and may be constructed as a combined sideway block system with a gap by appropriately combining them.
According to the present disclosure, as shown in
Recently, in accordance with ┌Natural Environment Conservation Act┐, object businesses, the selection methods, etc. for a biotope area ratio have been integrally prescribed in the notice, ‘Joint gap-permeable pavement’ was newly established. Further, the permeability test was prescribed to follow only the indoor constant-head permeability coefficient test method (KS F 4419) that can test only existing permeable blocks themselves, but a site permeation amount test method (KS F 2394) and a site permeability test method (ASTM C 1701) are also included to be able to test various permeable blocks. Accordingly, it finally became possible to realize commercialization of ‘joint gap-permeable pavement’ that is advantageous in securing a biotope area in a city and improving permeability.
The present disclosure is designed to follow the environment conservation concept called “biotope area ratio’ and can maintain well a permeation environment of roads in a city.
Further, the gap portion 30 formed between the front surface and the rear surface of the unit assembly block 10 may be formed such that the gap between blocks widens downward from above. Through this configuration, the gap between blocks widens as it goes to the lower portion of the blocks, thereby reducing clogging of the gap with a mixture. Further, an empty space is formed under the gap, so it is possible to prevent the gap from being clogged until a mixture flowing under the gap fills the lower space, whereby it is possible to prevent deterioration of permeability due to a mixture.
Further, the gap portion formed between the front surface and the rear surface of the unit assembly block 10 may be characterized in that one to five gap maintenance protrusions are formed, and many hollow portions in which rainwater or a mixture is collected may be formed.
Further, the hollow portion in which rainwater or a mixture is collected may be characterized by being integrally formed at the lower portion of the unit assembly block 10.
The side connection portions 20 to which the left and right sides of the unit assembly block 10 are physically inserted and coupled may be configured to be fitted in a circular or rectangular groove. As the side connection portions 20 are fitted in contact with each other, gravity is distributed to the entire sideway block system, whereby it is possible to resist passing of heavy vehicles, etc.
According to the present disclosure, connection portions are formed on the left and right sides such that they can be pushed and fitted to each other in a semicircular rounded shape or a trapezoidal rectangular shape, so blocks can be easily coupled with many permeable blocks. Accordingly, it is possible to prevent uneven settlement between blocks even though masonry joints (sand) are not provided between the blocks, it is possible to lift and separate damaged blocks by pushing a tool, etc. into the gap portion, and it is possible to replace a new standardized blocks with such damaged blocks. To this end, it is preferable to form the side connection portion 20 in a circular shape and the side connection portion 20 may be formed in a laid trapezoidal rectangular shape.
It may be possible to provide a combined sidewalk block system with a gap while combining the shape and number of the protrusions of the block in order to further distribute the fitting force between blocks and gravity. That is, the connection portions to which the left and right sides of the unit assembly block 10 are physically inserted and coupled may have many connection protrusions to be fitted in a circular or rectangular groove.
In short, the present disclosure can provide a sidewalk-roadway combined block system having improved rainwater permeability with a gap by improving the efficiency of discharging rainwater and a mixture of granules and powders through a gap structurally formed when combining the unit assembly blocks 10 in an assembly type. Further, there is an effect of providing a sidewalk-roadway combined block system with a gap that is assembled for a sidewalk at a connection portion with a parking lot, but can be firmly assembled using the fully solid first assistant unit assembly block 10 not having lower cavity portion, and can prevent breakage of a contact surface of corners.
Further, it is possible to provide a sidewalk-roadway combined block system with a gap that can induce a waterway or can be used as a cavity passing a communication cable by connecting the lower cavity-integrated second assistant unit assembly blocks 10 that can prevent a loss of sand, etc. due to a waterway formed through the lower cavity portion on a slope. Further, it is possible to provide a sidewalk-roadway combined block system with a gap that prevents generation of weeds between blocks by discharging down a mixture of granules and powders and is advantageous in construction to which a biotope area ratio is applied by securing water permeation sustainability.
