As shown in the drawings, the method of manufacturing a pitcher block according to an embodiment of the present invention positively uses recycled bottom ash, and in order to increase the coloring effect of the pigment, plasma processing that does not use a separate binder, (NO _x ) by the use of a photocatalyst that removes contamination of the nitrogen oxides (NO _x ) by air, and produces an environmentally friendly color aggregate. It is excellent in permeability by pressure molding with water-permeable block by using 2-component thermosetting resin, recycled glass fiber and curing accelerator, which is eco-friendly material without cement completely, and it can be used semi-permanently because it does not discolor or discolor. And contributes to prevention of depletion of groundwater and growth of trees, So that it is possible to manufacture a pitcher block for a roadway equipped with a purifying function.

Hereinafter, a method of manufacturing a pitcher block for a slideway according to an embodiment of the present invention will be described in detail.

As shown in FIG. 1, the method of manufacturing a pitcher block for a slideway according to an embodiment of the present invention includes a step of producing a color aggregate (S11), a step of mixing and agglomerating a color aggregate, a thermosetting resin and a recycled glass fiber, , A press molding step S14, a demolding step S15, and a curing step S16.

In the color aggregate production step (S11), the recycled bottom ash to be discarded after being used in the field of thermal power plants is collected and the ground colored ash particles are pulverized to produce an environmentally-friendly colored aggregate. In the case of the color aggregate produced in this step, the bottom ash particles crushed so as to have an average particle size of less than 5 mm, less than 30 mm, less than 50 mm and less than 100 mm, The bottom ash particles are transported by the conveyor which is the transfer device 190 and the first crusher 110a and the second crusher 110b are transported while being conveyed by the conveyor 190. [ The first stage stirrer 150b and the second stage stirrer 150b are connected to each other through the first stage 110b and the second stage 120b. A heating furnace 160b, a cooling dryer 170, and a photocatalyst coating device 180b. The color aggregate production step will be described later in detail.

In the mixing step (S12) of mixing the color aggregate, the thermosetting resin and the recycled glass fiber, the color aggregate prepared in the previous step, the two-component type thermosetting resin, the recycled glass fiber and the curing accelerator are mixed and stirred in the third stirrer 210 . At this time, 70 to 95% by weight of the color aggregate, 4 to 30% by weight of the thermosetting resin, 0.1 to 5% by weight of the recycled glass fiber and 0.001 to 3% by weight of the curing accelerator are mixed. Here, the thermosetting resin and the recycled glass fiber mixed with the color aggregate completely replace the cement, thereby binding the colored aggregate to the high strength. The curing accelerator promotes the curing of the thermosetting resin, thereby shortening the curing time.

In the step of injecting the releasing agent S12, a water-soluble releasing agent is injected into the press molding machine 220 before the mixture of the agglomerated aggregate, the thermosetting resin, the recycled glass fiber and the curing accelerator is injected into the press molding machine 220 . Here, the water-soluble mold release agent is intensively injected into the upper mold and the lower mold of the press molding machine 220. This process prevents adhesion of the thermosetting resin and the color aggregate to the press-molding machine 220, thereby facilitating demoulding of the water-permeable block formed from the press-molding machine 220, which helps to reduce the entire process time.

In the press molding step S14, the mixture of the agitated color aggregate, the thermosetting resin, the recycled glass fiber, and the curing accelerator is put into a pressure molding machine 220 and then pressurized to form a water permeable block.

In the de-molding step S15, the water-permeable block formed in the press-molding machine 220 is demolded from the press-molding machine 220. [ The demoulding of such a permeable block is facilitated without the problem of adhesion of the thermosetting resin or the color aggregate due to the water-soluble mold release agent sprayed in the previous step.

In the curing step S16, the water permeable block demagnetized in the press-forming machine 220 is cured while gradually passing the biogas 230 installed along the conveyor, which is the transfer device 190, or storing it for a sufficient time. The permeable block thus cured is measured and packaged through the packing machine 240. Here, the bilayer 230 is configured to have a plurality of cooling fans, and the cooling fan can be selectively used to control the curing time.

As a result, it is possible to reduce the maintenance cost by making it possible to use semi-permanently because of discoloration or discoloration because it is excellent in water permeability by recycling the waste material to be recycled. It also contributes to prevention of groundwater depletion and promotion of tree growth, It is possible to obtain a pitcher block for a roadway which has no problem of discharge and has an air purification function.

Hereinafter, the color aggregate production step (S11) will be described in more detail.

The color aggregate manufacturing step S11 includes a recycling bottom ash crushing step S101, a foreign matter removing step S102, a particle size separating step S103, a cleaning step S104, a plasma processing step (S105), a pigment mixing and stirring step (S106), a heating coloring step (S107), a protective agent mixing and stirring step (S108), a protective agent heating impregnation step (S109), a cooling drying step (S110) and a photocatalyst applying step .

In the recycling bottom ash crushing step (S101), the bottom ash generated in the thermal power plant and classified as waste after being buried in the sea is collected and crushed to have an average particle diameter of 5 mm or less, 30 mm or less, 50 mm or less, Make bottom ash particles. For this purpose, it is possible to crush the bottom ash particles until the required size of the bottom ash particles is reached, but if the environment permits, the first crusher 110a and the second crusher 110b may be connected in series It is preferable to grind the recycled bottom ash in a stepwise manner from the viewpoint of the pulverization quality.

In the above-described foreign matter removal step (S102), unnecessary fine powders and various foreign substances contained together with the crushed bottom ash particles are removed. 5, the foreign matter remover 120 vibrates and vibrates the bottom ash particles S by the diaphragm 121, while the blower 123 applies the air pressure and the duct 124 on the other side, The electromagnet 125 sucks and removes the metallic foreign matter E2 from the upper side by sucking and removing the foreign matter E1 blown by the wind pressure. The foreign matter removal process is performed by controlling the time depending on the amount of the bottom ash particles (S). It is possible to prevent the bottom ash particles S from being separated from the diaphragm 121 by installing a fence 121a constituted by a mesh net around the upper surface of the diaphragm 121, So that the magnetic force by the electromagnet 125 is allowed.

In the particle size separation step (S103), the operation of separating the bottom ash particles obtained from the recycled bottom ash by particle size is performed. For this purpose, the separator 130 has a plurality of meshes or pores having different sizes of pores, and separates the pulverized bottom ash particles by particle size.

In the cleaning step (S104), the cleaning device 140a injects high-pressure water to clean the bottom ash particles separated by particle size. As a result, it is possible to remove fine powder remaining on the surface of the bottom ash particles without being removed in the preceding foreign substance removing step (S102). This process helps improve the efficiency of subsequent plasma processing operations.

 In the plasma treatment step (S105), the surface of the washed bottom ash particles is subjected to plasma treatment in order to increase the coloring efficiency of the pigment to the bottom ash particles. For this, the atmospheric pressure plasma processing apparatus 140 can be simply installed on the line without being carried out in a vacuum apparatus or a very large mechanical apparatus having a large size. At this time, the flow rate of the bottom ash particles is controlled to about 1 to 2 m and the plasma treatment time is set to 1 to 5 minutes, while the flow rate of nitrogen and oxygen gas is controlled to about 60: . By such plasma treatment, an etching phenomenon appears on the surface of the smooth ash particles at the beginning, and coarse micro-craters are formed, thereby increasing the root mean square (RMS) roughness value. This makes it possible to easily bond the pigment component to the bottom ash particle surface. If the glass fiber particles and the pigment are mixed and agitated without performing the above-described plasma treatment step (S105) and the operation of heating and coloring is performed immediately, the amount of the pigment must be increased and the time required for mixing and stirring and heating and coloring is greatly increased There is a difficulty to make. However, through such plasma treatment, the amount of pigment and the time required for coloring can be greatly reduced, and the coloring quality is also improved overall.

In the pigment mixing and stirring step (S106), the plasma treated bottom ash particles and the pigment are mixed and sufficiently stirred by a dedicated first agitator (150a). Whereby the pigment is uniformly dispersed and applied to the surface of the bottom ash particle in a sufficient amount.

In the heating and coloring step (S107), the bottom ash particles and the pigment stirred in the first stirrer 150a are heated in the coloring furnace 160a to stably color the pigment on the bottom ash particles. In this case, the heating temperature is suitably from 200 ° C to 800 ° C.

In the protective agent mixing and stirring step (S108), a thermosetting resin, a UV stabilizer, and a curing accelerator are mixed and stirred with the colored bottom ash particles to perform surface coating. The use of the thermosetting resin, the UV stabilizer and the curing accelerator is to protect the bottom ash particles from the colored pigments from flying and to make them glossy. Here, they are applied separately in the step of coloring together with the pigment It is a point. Thus, when coloring the pigment, the coloring operation can be performed by setting the heating temperature more freely without considering the limitation of the heating due to the thermosetting resin. In addition, since the surface of the pigment is protected after the coloring of the pigment is completely completed, But also in terms of protecting the surface of the colored bottom ash particles. The blending ratio of the bottom ash particles is 50 to 90% by weight, the pigment is 1 to 10% by weight, the thermosetting resin is 1 to 30%, the UV stabilizer is 0.1 to 5%, and the curing accelerator is 0.1 to 5% by weight.

In the protective agent heating impregnation step (S109), the bottom ash particles coated with a thermosetting resin, a UV stabilizer and a curing accelerator are impregnated into the heating furnace 160b. At this time, the mixture is firstly heated to a temperature of 300 to 780 ° C, and then is secondarily heated to a temperature of 300 to 780 ° C.

In the cooling and drying step (S110), the bottom ash particles impregnated with the protective agent are cooled and dried in the heating furnace (160b). For this, as shown in FIG. 4, the bottom ash particles heated in the heating furnace 160b are passed through a cooling dryer 170 installed along a conveyor, which is a conveying device 190. The cooling and drying machine 170 includes a box-shaped main body 171 for providing a passage through which a conveyor for conveying the bottom ash particles can pass, and a plurality of blowing fans 172 disposed along the conveyor in the box- Thereby effectively cooling and drying the heated bottom ash particles.

In the photocatalyst applying step S111, the photocatalyst is applied to the cooled bottom ash particles in an amount of 20 to 100 L per m ² using a photocatalyst coating device 180b containing a high-pressure sprayer. As the photocatalyst, titanium oxide (TiO ₂ ) is taken into consideration, but in order to increase the efficiency in visible light, a composite of titanium oxide and tin oxide to which a metal ion is added or a composite of a titanium oxide and a metal tungsten oxide bonding structure . For reference, it can be said that the production of the color aggregate is almost completed when the photocatalyst applying device 180b is disposed. In the next position of the photocatalyst applying device 180b, a product packing machine P100 for measuring and packing the color aggregate coated with the photocatalyst is disposed And can be used as needed. This made the photocatalytic coating step (S111) When removing the contamination of the nitrogen oxides (NO _X) by the vehicle exhaust gas and effective to purify the air.

In addition, when the photocatalyst application step S111 is carried out by coating the citrus oil extracted from the citrus peel, which is a recycled material at the time of applying the photocatalyst, on one-to-one basis and coating, high quality color aggregate having the unique direction of the citrus peel and antibacterial function can be produced. Here, it is possible to extract the citrus oil from the citrus peel as much as possible by a solvent extraction method in which hexane is used as a solvent in an oil extraction apparatus. To this end, citrus oil is extracted by adding hexane to the crushed citrus peel in the oil extracting apparatus, and the citrus oil having high purity is obtained through a continuous process of distilling the extracted citrus oil.

Here, it should be noted that a unique photocatalyst-oil mixer 180a is used for uniformly mixing the photocatalyst and the citrus oil to obtain a high quality photocatalyst-oil mixed water. As a result, it is possible to realize an air purification function of a photocatalyst and a high quality eco-friendly color aggregate and a pitcher block for antibacterial activity of citrus oil extracted from a tangerine peel.

6 and 7, the photocatalyst-oil mixer 180a includes a main pipe 10, an injection nozzle 20, a phase conversion module 30, a redoing module 40, (50).

The main tube 10 is supplied with free water and citrus oil, which are ultrafine particles of a photocatalytic diluent, in the phase conversion module 30, and performs a primary mixing while strongly contacting and mixing. The main tube 10 is connected to the phase change module 30 so that the tip of the main tube 10 can receive free water of the photocatalytic dilution liquid sent from the phase conversion module 30, And also receives the citrus oil from the injection nozzle 20. Inside the body having a pipe shape, a protrusion 11 for reducing the inner diameter and widening the inner diameter and forming a narrow venturi tube-shaped flow path at the intermediate point is provided. Such protrusions 11 induce the free water of the photocatalytic diluent and the citrus oil to make strong contact with each other while flowing at an increased rate in the relatively narrow channel 10a by the venturi effect, as can be seen in Fig. The chambers 11a and 11b connected to the citrus oil tank through the first supply pipe 62 of the three-way valve 60 for storing and temporarily storing the citrus oil are formed in the protrusion 11, A plurality of first injection holes 11c are formed along the circumferential direction of the inner circumferential surface to receive and discharge the citrus oil from the chambers 11a and 11b on the inner circumferential surface of the intermediate point corresponding to the point where the flow paths are narrowly formed, A plurality of second injection holes 11d for supplying and discharging the citrus oil from the chambers 11a and 11b are formed at the rear end points of the protrusions 11 along the circumferential direction of the rear end. Thereby, it is possible to supply the citrus oil at the same time as the injection nozzle 20 at a more various points, so that it is possible to more effectively contact the free water. In particular, the citrus oil injected through the first injection hole 11c formed at the midpoint of the projection 11 can vigorously contact the free water flowing at the fastest speed, The citrus oil injected through the second injection hole 11d formed so as to be in a calm contact with the free water flowing at a relatively slow speed. With this diversity, it is possible to increase the effect of mixing and contacting the free water of the photocatalytic diluent with the citrus oil, and thus the mixing quality can be raised to a high level from the beginning.

In addition, an axial flow fan 12 for sending out the free water of the photocatalytic dilution liquid sent out from the centrifugal fan 32 of the phase conversion module 30 in the form of a whirlwind is provided in the front end portion of the main tube 10 Respectively. As shown in FIG. 8, when the axial flow fan 12 is operated, the flow rate of the free water and the flow of the citrus oil is rapidly formed by the venturi effect and strong contact is made with each other, The complex action of mixing with citrus oil occurs in the form of strong whirlwind. Therefore, contact and mixing between free water and citrus oil, which is a photocatalytic dilution of ultrafine particulate state, and thus initial mixing, can occur very quickly and effectively. For reference, it is sufficient that the axial fan (12) has the same shape as the fan adopted in the air circulator used in recent households.

The injection nozzle 20 serves to supply the citrus oil in the main tube 10 in a direction coinciding with the flow direction of the free water. For this, the injection nozzle 20 is connected to the citrus oil tank through the second supply pipe 63 of the three-way valve 60 to receive the liquid citrus oil. In the state of passing through the front end wall of the main pipe 10, Is formed so as to face the flow path formed narrowly by the projecting portion (11) while being positioned on the center line of the main body tube (10). 7, the injection nozzle 20 includes a first nozzle unit 21 formed from the wall of the main tube 10 to a center line thereof and a second nozzle unit 21 extending from the first nozzle unit 21 to the center line of the main tube 10, And a second nozzle portion 22 which extends along the narrow path 10a and whose end is located close to the narrow flow path 10a by the protrusion 11. [ Such injection nozzles 20 assist in accelerating the flow rate of free water while jetting the citrus oil in the vicinity of the narrow flow path 10a by the projections 11 in the direction of the free flow of the photocatalytic diluent. This contributes greatly to the contact of the free radical of the photocatalytic diluent and the citrus oil at a faster velocity in the narrow channel 10a at the midpoint of the projection 11 of the main tube 10.

The phase conversion module 30 converts the diluted photocatalyst supplied through the transfer pipe P1 into the ultrafine particulate free phase. To this end, the phase conversion module 30 has a flange and has a pipe-shaped body communicating between the transfer pipe P1 and the main pipe 10, and a photocatalytic dilution liquid, which is transferred through the transfer pipe P1, And a spray head 31 for spraying the water into the free water. The spray head 31 may be a spray head 31 (nozzle) applied to a water spraying fire extinguishing system, but it is preferable that the spray head 31 is improved and improved in corrosion resistance and durability. When the photocatalytic dilution liquid supplied from the transfer pipe (P1) is converted into ultrafine particulate free water without using it as it is, the contact area for contacting the citrus oil can be secured at a remarkable level, It is very important in that it is possible.

In addition, a centrifugal fan (32) is provided inside the phase conversion module (30) to deliver the free water sprayed from the spray head (31) at a lower speed. In the case of the axial flow fan 12, if the centrifugal fan 32 has a function for pushing and discharging the free water, the centrifugal fan 32 will overcome the resistance due to the installation of the spray head 31, And is suitable for dispensing to the centrifugal fan (32). In the present invention, the centrifugal fan (32) and the axial fan (12) are disposed side by side in series to maximize the advantage between the centrifugal fan (32) and the axial flow fan (12).

The redemption module (40) receives the mixed solution of the free water of the photocatalytic dilution solution and the citrus oil, which have been mixed in the main tube (10) while passing through the main tube (10) It plays a role. To this end, the redemption module 40 is connected to the rear end of the main pipe 10 by a pipe-shaped body and receives a mixture of the free water and the citrus oil mixed via the main pipe 10, A plurality of grilles 41, 42, 43 (grill) having a plurality of micropores formed in a manner blocking the flow path are arranged in series with a spacing therebetween. According to the drawing, three grills 41, 42, and 43 are shown as being arranged. According to this configuration, as the mixed liquid passes through the grill layer formed by the grilles 41, 42, and 43, The mixing quality of the citric oil with respect to the photocatalyst diluent can be gradually increased and the spacing spaces 44a, 44b formed behind the grilles 41, 42, 43 each time the mixture liquid passes through the respective grilles 41, 44b and 44c, the mixture of the photocatalytic diluent and the citrus oil becomes more active while the turbulent flow occurs.

Hereinafter, a permeable block manufacturing system for implementing a method of manufacturing a permeable block according to an embodiment of the present invention will be described in detail.

3 to 9, the permeable block manufacturing system includes a first crusher 110a and a second crusher 110b, a foreign matter remover 120, a particle size separator 130, a cleaning device 140a, A plasma processing apparatus 140b, a first stirrer 150a and a second stirrer 150b, a coloring furnace 160a, a heating furnace 160b, a cooling drier 170, a photocatalyst-oil mixer 180a, A series of steps for manufacturing a slip porthole block basically including a device 180b, a transfer device 190, a third stirrer 210, a press molding machine 220, a balancer 230, a packing machine 240 and a controller .

Hereinafter, each component will be described in more detail.

Here, the first crusher 110a and the second crusher 110b are installed in series to crush recycled bottom ash in a stepwise manner, thereby reducing the load on the crusher, which is preferable in terms of crushing quality of the bottom ash.

The foreign material removing unit 120 removes unnecessary fine powders and various foreign substances contained together with the bottom ash particles prepared by pulverizing the recycled bottom ash. 5, the foreign substance remover 120 includes a diaphragm 121 for vibrating the bottom ash particles while being supported by the actuator 122, a blower 120 for applying air pressure to one side of the diaphragm 121, A duct 124 installed on the diaphragm 121 for sucking and removing foreign matter blown by the wind pressure from the other side of the diaphragm 121 and a metallic foreign matter mixed with the bottom ash particles, And an electromagnet 125 to be adsorbed and removed. According to this configuration, the foreign material remover 120 vibrates the bottom ash particles S crushed by the diaphragm 121, while the blower 123 applies the wind pressure on one side and the duct 124 on the other side The foreign substance E1 blown by the wind pressure is sucked and removed, and on the upper side, the electromagnet 125 adsorbs and removes the metallic foreign matter E2. This makes it possible to quickly remove various foreign substances mixed with the bottom ash particles. On the other hand, along the periphery of the upper surface of the diaphragm 121, a fence 121a constituted by a mesh net is installed. This serves to allow the wind pressure by the blower 123 and the magnetic force by the electromagnet 125 while preventing the bottom ash particles S from being separated from the diaphragm 121.

The particle size separator 130 separates the ground bottom ash particles by particle size. For this purpose, the particle size separator 130 has a plurality of meshes or pores having different sizes of pores, and separates the pulverized bottom ash particles by particle size.

The cleaning apparatus 140a cleans the bottom ash particles using high-pressure water in advance of the plasma treatment for the bottom ash particles. As a result, it is possible to quickly remove fine foreign substances and various germs remaining on the surface of the bottom ash particles.

The plasma processing apparatus 140b plasma-processes the surface of the washed bottom ash particles before mixing the bottom ash particles with the pigment to improve the coloring efficiency of the pigments with respect to the bottom ash particles. For this, the atmospheric plasma processing apparatus 140b can be simply installed on the line without being carried out in a vacuum apparatus or a very large mechanical apparatus having a large size. When such a plasma processing apparatus 140b is provided, micro-craters may be formed on the surface of the bottom ash particles to increase the root mean square (RMS) roughness value. This makes it possible to easily bond the pigment component to the bottom ash particle surface.

The first stirrer 150a mixes the plasma treated bottom ash particles with the pigment and stirs them sufficiently. Whereby the pigment can be uniformly dispersed and applied to the bottom ash particle surface in a sufficient amount.

The coloring furnace 160a serves to stably color the pigment on the bottom ash particles by heating the bottom ash particles and the pigment stirred in the first stirrer 150a in the coloring furnace 160a. The heating temperature in the coloring furnace 160a is suitably from 200 ° C or higher to 800 ° C.

The second stirrer 150b mixes and agitates the thermosetting resin, the UV stabilizer, and the curing accelerator to the colored bottom ash particles to perform surface coating.

The heating furnace 160b functions to impregnate the bottom ash particles coated with a thermosetting resin, a UV stabilizer, and a curing accelerator on the heating furnace 160b. Since the heating furnace 160b is provided with the same kind of the coloring furnace 160a as the coloring furnace 160a, it is preferable that the heating furnace 160b is provided separately.

The cooling and drying device 170 serves to cool and dry the bottom ash particles impregnated with the protective agent in the heating furnace 160b. To this end, the cooling and drying device 170 passes the bottom ash particles heated in the heating furnace 160b to a cooling dryer 170 installed along a conveyor, which is a transfer device 190, as shown in FIG. The cooling and drying machine 170 includes a box-shaped main body 171 for providing a passage through which a conveyor for conveying the bottom ash particles can pass, and a plurality of blowing fans 172 disposed along the conveyor in the box- do. According to such a configuration of the cooling and drying device 170, the heated bottom ash particles can be rapidly cooled and dried.

The photocatalyst coating device 180b has a plurality of high-pressure sprayers capable of spraying the photocatalyst in distilled water in a diluted state at a high pressure, and the photocatalyst is applied in an amount of 20 to 100 L per m ² . As the photocatalyst, titanium oxide (TiO ₂ ) is taken into consideration, but in order to increase the efficiency in visible light, a composite of titanium oxide and tin oxide to which a metal ion is added or a composite of a titanium oxide and a metal tungsten oxide bonding structure It is possible. The production of the colored aggregate is almost completed when the photocatalyst applying device 180b is passed through the apparatus. Meanwhile, in the case of the photocatalyst applying device 180b, the citrus oil extracted from the citrus peel, which is a recycled material when the photocatalyst is applied, is mixed and applied. In this case, the above-described photocatalyst-oil mixer 180a is used, and thus it is possible to produce high quality color aggregates and permeable blocks having the unique direction and antimicrobial function of the citrus peel.

The third agitator 210 mixes and agitates the color aggregate prepared through the preceding facilities with a two-component thermosetting resin, a glass fiber as a recycled material, and a curing accelerator. At this time, 70 to 95% by weight of the color aggregate, 4 to 30% by weight of the thermosetting resin, 0.1 to 5% by weight of the recycled glass fiber, and 0.001 to 3% by weight of the curing accelerator are mixed. Here, the thermosetting resin and the recycled glass fiber mixed with the color aggregate completely replace the cement, thereby binding the colored aggregate to the high strength. The curing accelerator promotes the curing of the thermosetting resin, thereby shortening the curing time.

The press molding machine 220 presses the mixture of the color aggregate, the thermosetting resin and the curing accelerator stirred in the third stirrer 210 into a water permeable block. The pressure molding machine 220 is sprayed with a water-soluble mold release agent before press molding to prevent the problem of adhesion of the thermosetting resin and the color aggregate.

The bilayer 230 serves to cure the permeable block demolded in the press-molding machine 220 by gradually passing the bilayer 230 installed along the conveyor, which is the transfer device 190, or storing the brick 230 for a sufficient length of time. The bilayer 230 is provided with a plurality of cooling fans so as to control the curing speed for the formed waterproof block.

The packing machine 240 functions to measure and pack the cured water permeable block.

The controller, in conjunction with the various devices mentioned above, including the transfer device 190, serves to control the entire processing and transport of the glass fiber particles.

The thus constructed permeable block manufacturing apparatus smoothly performs the unique series of processes for manufacturing the pitching block for the slip road by appropriately arranging the various devices mentioned above.

As a result, it is possible to use semi-permanent use because it is excellent in permeability and does not discolor or discolor, and thus it is possible to reduce maintenance costs, contribute to prevention of groundwater depletion and promote growth of trees, It is also possible to obtain a pitcher block for a roadway equipped with an air purification function.
