Description

{SIDEWALK-ROADWAY COMBINED BLOCK SYSTEM IMPROVED RAINWATER PERMEABLITY WITH GAP}

The present invention relates to a joint gap block system for sidewalks with excellent permeability and durability. More specifically, it is a prefabricated system that is easy to construct and not only allows rainwater to pass through the gap created structurally when combined, but also has an efficiency in discharging granular and powdery contaminants. This is about a joint gap block system for a roadway that is advantageous for construction by applying an ecological area ratio that allows for rainwater permeability and water storage management by ensuring sustainability of water permeability by improving water permeability.

Recently, with the rapid progress of urbanization, the number of cement and paved roads has increased, leading to an increase in impervious surfaces. It appears that more than 73% of urbanized areas are impervious surfaces.

This increase in impervious surfaces causes flooding due to rainwater pouring onto roads during localized heavy rain due to climate change, and during droughts, a heat island phenomenon may appear due to water shortage and high heat of the ground.

In order to solve these problems, the existing porous water permeable blocks for roads were proposed to have pores clogged with foreign substances, and the water permeability function was found to be significantly reduced within 6 months after construction. Accordingly, maintenance standards require that the blocks be vacuumed at least twice a year. “High-pressure suction cleaning is recommended.”

In addition, existing permeable blocks have weak inter-block bearing capacity, so they fill joints with sand, etc. to increase bearing capacity. In this process, sand fills the pores of the block for permeability, which not only rapidly reduces permeability, but also causes weeds to grow between blocks, making it unsightly. There is also the problem of having to remove it because it harms it.

For example, in “Road paving blocks, road paving structures using the same and their construction methods” in Sun Registration Patent No. 10-1227275, high-performance permeable paving surface blocks with excellent water permeability are used to drain runoff from a wide area of the road and surrounding roads. A technology has been proposed that allows rainwater permeated from the upper pavement surface to infiltrate into the ground and underground by permeating to the lower part and constructing deep blocks at the bottom of the pavement surface.

In addition, Republic of Korea Patent Publication No. 10-2016-0089918 discloses a road block that improves the rainwater permeability sustainability by improving the discharge efficiency of granular and powdery contaminants, a road pavement structure using the same, and a construction method thereof. However, the structure There is a problem that not only is mass construction difficult due to the complex S-shaped fitting connection with other blocks, but also it is difficult to replace damaged parts.

Recently, in accordance with the Natural Environment Conservation Act, the ecological area ratio's applicable projects and calculation methods have been integrated and regulated in the notification, and 'combined gap permeable pavement' has been newly established, and the permeability performance test is also conducted at an indoor still water level where only existing self-permeable blocks can be tested. It was revised from only following the permeability coefficient test method (KS F 4419) to include the field water permeability test method (KS F 2394) and the field infiltration capacity test method (ASTM C 1701) to enable testing of various permeable blocks, thereby improving the city's safety. A path has been opened to realize the commercialization of combined gap permeable pavement, which is advantageous for securing ecological area and improving water permeability.

The present inventor has been researching and developing combined gap blocks for roads subject to the application of the ecological area ratio for many years, and has not only allowed rainwater to pass through the prefabricated gap, but also improved the discharge efficiency of contaminants from the granular and powdered materials to ensure sustainability of water permeability.

In the following description of the present invention, if a detailed description of a related known function or configuration is judged to unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

First, the present invention is easy to construct by prefabricating basic blocks, and not only allows rainwater to pass through structural gaps created by combining basic blocks, but also improves the discharge efficiency of contaminants from granular and powdery materials to ensure sustainability of water permeability. Provides a combined gap road block system that is advantageous for its application.

Figures 4 to 6 are diagrams showing the principle of the joint gap sidewalk block system (1) according to an embodiment of the present invention.

In the present invention, sidewalk use includes sidewalk blocks on sidewalks used by pedestrians and vehicular blocks that allow cars to pass.

In the present invention, the unit assembly block 10 is easy to construct as a prefabricated unit, and not only allows rainwater to pass through the structural gap as it is combined, but also improves the discharge efficiency of contaminants in the granular and powdery materials to ensure sustainability of water permeability. It can be constructed on the floor of parking lots, parks, walking trails, etc., and temporarily stores moisture using the gap space between blocks, and then gradually absorbs it into the ground, creating a path for traffic caused by local heavy rain or melting accumulated snow. It can be used to prevent flooding and to prevent clogging of air gaps, which is a disadvantage of existing permeable blocks.

In the coupling gap block system according to an embodiment of the present invention, as shown in Figure 1, the side connection part 20, which is a connection part where the left and right sides of the unit assembly block 10 are physically inserted and joined, is formed, and the unit assembly block ( 10), a rear gap is formed at a position corresponding to the front gap 30, and an upper groove 60 is formed on the upper surface, which is a groove made of a plurality of valleys through which rainwater flows down to the front and rear gaps. , a lower pupil part 40 is formed in the lower part where rainwater or impurities falling downward from the gap accumulate.

In the present invention, the gap is formed in the form of an inverted triangle with the lower part cut away from the front part 31 and the central area of the front part 31, and each gap is formed in the vertical direction with the upper area narrower than the lower area. The holding stage 32 and the rainwater guide 33 start from the lower part at a preset distance from the upper surface, and slopes are formed on both sides to allow rainwater to slide, and when constructing a combined block system as shown in Figure 3 (a), As shown in Figure 3 (b) and Figure 6, in order to prevent damage to the corners of the product during transportation and construction, the area starting from the lower part with a preset gap compared to the upper surface may have a damage prevention gap formed in a flat shape at regular intervals. , In addition, an inclined portion may be placed at the edge of the top of the side connection to prevent breakage due to collision between the unit assembly blocks 10.

Meanwhile, in Figure 2a, the first auxiliary unit assembly block 10a without a lower cavity is fastened between a preset number of unit assembly blocks 10, so that it is installed in a place where water should not flow, such as a slope, to form a water channel, thereby forming a water channel through sand or soil. This is a block that can prevent the loss of . In addition, as shown in Figure 4, the first auxiliary unit assembly block 10a without a lower cavity is harder than the unit assembly block 10 with a lower cavity, so it can be constructed as a roadway on a side with frequent vehicle traffic.

Figure 2b is a second beam unit assembly block 10b, which is a modified form of the unit assembly block 10, and a guide 50 in the shape of a horizontal plate is added, so that the lower cavity is manufactured in a form integrated with the block, and the lower cavity is ( 40), not only can a waterway be guided to prevent the phenomenon of digging in the lower stratum, but it can also be installed on one side of a road on a slope as a substitute for a waterway, and can be used as a utility outlet to pass communication cables, etc. by connecting the lower cavities. You can.

At this time, the unit assembly block 10 may be characterized as being made of concrete or synthetic resin material. In the case of the porous water permeable blocks used previously, the water permeability of the block itself is difficult to maintain for a long period of time due to clogging caused by contaminants at the beginning of construction, and the bending strength is reduced due to the pores of the block itself, which has the disadvantage of being easily broken. The invention eliminates the voids in the block itself and manufactures the block using a compression method to increase the bending strength. Instead, rainwater permeates through the gap between blocks, and impurities such as rainwater or sand or dust that fall on the upper surface of the block are also sent down to the bottom through the gap. At this time, to prevent the gap from being blocked by impurities, the lower part is made wider than the upper part.

The unit assembly blocks 10 (10) can be manufactured in various forms depending on the construction area and situation, and they can be appropriately combined to construct a combined gap road block system.

The present invention can be used continuously from left to right as shown in FIG. 3, and blocks can be arranged in various patterns. As we have seen before, in the case of existing porous permeable blocks, the permeability of the block itself at the beginning of construction is blocked by contaminants, and the permeability decreases rapidly within 6 months. As it has been pointed out that there are problems in using it as an indicator to evaluate impervious surface pavement construction in the city, recently a permeability test method and construction method based on the concept of 'ecological area ratio' has been adopted.

Recently, in accordance with the Natural Environment Conservation Act, the projects subject to the ecological area ratio and calculation methods have been integrated and regulated in the notification, and a new 'combined gap permeable pavement' has been established, and the permeability performance test is also an indoor static water level that can only test existing self-permeable blocks. It was revised from only following the permeability coefficient test method (KS F 4419) to include the field water permeability test method (KS F 2394) and the field infiltration capacity test method (ASTM C 1701) to enable testing of various permeable blocks, thereby improving the city's safety. A path has been opened to realize the commercialization of combined gap permeable pavement, which is advantageous for securing ecological area and improving water permeability.

The present invention is designed to fit the environmental conservation concept of 'ecological area ratio' and can maintain the pervious environment of urban roads.

In addition, the gap 30 formed between the front and back of the unit assembly block 10 can be formed to widen as the gap between blocks goes from the top to the bottom. By configuring it in this way, the gap between blocks widens as it goes down to the bottom of the block, reducing the phenomenon of gap clogging by contaminants. By forming an empty space at the bottom of the gap, contaminants flowing into the lower part of the gap fill the gap until it fills the lower space. It is possible to prevent clogging of the water, thereby preventing a decrease in water permeability due to contaminants.

In addition, the gap formed between the front and rear of the unit assembly block 10 may be characterized by forming 1 to 5 gap maintenance protrusions, and a plurality of hollow parts where rainwater or impurities accumulate may be formed.

In addition, the hollow part where rainwater or impurities accumulate may be formed integrally with the lower part of the unit assembly block 10.

The side connection portion 20, where the left and right sides of the unit assembly block 10 are physically inserted and joined, can be configured to fit into a circular or square groove. As the side connection parts 20 are fitted in this way, gravity is distributed to the entire road block system, making it possible to withstand the passage of vehicles with heavy loads.

The present invention forms a semicircular curved surface or a trapezoidal square on the left and right sides so that they can be pushed together to enable easy connection with other permeable blocks, thereby preventing floating settlement between blocks even without adding grout (sand) between the blocks. Damaged blocks can be separated by lifting them into the gap with a tool, etc., and replaced with new blocks that meet the specifications. For this purpose, the side connection portion 20 is preferably configured in a circular shape, and a lying trapezoidal rectangle is also possible.

In order to further distribute the engagement and gravity between blocks, a combined gap sidewalk block system can be provided by combining various shapes and numbers of protrusions in the gap. That is, a plurality of connecting protrusions of the connecting portions where the left and right sides of the unit assembly block 10 are physically inserted and joined can be formed to fit into circular or square grooves.

To summarize the above description, the present invention is a combined gap block system for roadways with excellent water permeability sustainability by improving the discharge efficiency of rainwater and contaminants of granular and powdery substances through the gap created structurally while combining unit assembly blocks (10) in a prefabricated manner. In addition, by using the first auxiliary unit assembly block (10), which is assembled for use as a sidewalk in the parking lot and connection area but is tightly packed without a lower cavity, it is not only firmly assembled to allow vehicle traffic, but also has a corner contact surface. It has the effect of providing a combined gap block system for sidewalks that can prevent cracking.

In addition, the present invention connects the second auxiliary unit assembly block (10) integrated with the lower cavity, which can prevent the loss of sand, etc. by creating a waterway through the lower cavity at the ramp portion to guide the waterway or pass through the communication cable. Not only can it provide a combined gap block system for roadways that can be used as a common conduit, but it also discharges granular and powdery debris to the bottom to prevent the occurrence of weeds between blocks and ensures sustainability of water permeability, allowing application of the ecological area ratio. We can provide a joint gap block system for sidewalks that is advantageous for construction.
