FIG. 7 is a block diagram showing a method of using a block body 5 in which a cobblestone 1 is housed in a net frame 5a or a housing frame 5b or the like.
8 to 11 show another embodiment of the cobblestone 1 manufactured with waste plastic (waste plastic) 1P.

First, a method for manufacturing the cobblestone 1 will be described with reference to a manufacturing apparatus 2 shown in FIGS. The manufacturing apparatus 2 includes a hopper (supply port) 20 into which the waste plastic (waste plastic material) 1P is charged, a melting chamber 21 that heats and agitates the supplied waste plastic 1P to melt, and a melting chamber 21 that melts the waste plastic 1P. A molding chamber 23 having a mold 22 for the stone 1 detachably connected to the terminal end portion, and a cooling device for cooling the extruded waste plastic which is sent out linearly from the mold 22 and is in a high temperature state with a soft rod-like body. 25, a cutting device 26 that cuts the cooled extruded waste plastic into a predetermined length, and a storage device 7 that stores the cutting stone 1 that is cut into granules by the cutting device 26 and formed into a granular material (lumps). It is configured.

The waste plastic 1P is generally made of defective or surplus plastic products discarded from factories, or multi-sheets or ridged boards used as agricultural materials.
In addition, a plastic product or the like discarded at home is directly or pulverized into the hopper 20 to be melted.
To be sent to In the melting chamber 21, a stirring body 21a with stirring blades and a transfer spiral body 21b are horizontally provided so as to be rotatable up and down, and the peripheral wall is not generated at 200 to 350 ° C. by generating a harmful gas by an appropriate heating means. By heating the waste plastic 1P to an appropriate degree, the waste plastic 1P is dissolved well into a paste that can be easily molded.

The molding chamber 23 has an extruder 23a formed of a helical body therein, and the molten waste plastic 1P
Is extruded from a molding hole 22a opened in the molding die 22 to form a linear material (extruded waste plastic).
At the end of the molding chamber 23, various molding holes 22a to be described later are formed.
22 | and 22 # having the following can be attached and fixed so as to be detachable and replaceable. The molding die 22 mounted in FIG.
Three 2a are arranged in a straight line and drilled. The cooling device 25 cools the linear material extruded from the molding hole 22a of the molding die 22 with cooling water,
It is made soft so that it can be cut and solidified into a soft state of appropriate hardness.

The cutting device 26 cuts the rod-shaped linear material from both sides in a sandwiching manner (cutting scissors) by arranging the cutters 26a arranged on both sides of the linear material so as to be able to reciprocate by a driving mechanism 26b. Like that. The linear material cut by the cutting device 26 is used to adjust the cutting speed of the cutter 26a or the extrusion rate of the molding chamber 23 so that the granulated material 1 of a desired length can be cut.
The shape of the end face to be cut with scissors can be appropriately changed and formed by changing the hardness of the linear material by cooling.

In the illustrated example, the cobblestone 1 is cooled by the cooling device 25 to such an extent as to maintain a soft (soft) state before the wire is completely hardened, and the soft wire is cut from both sides by a cutter 26a. , 26a, the granular material cut as shown in FIG. 3 is cut into a small-diameter cross section whose both ends are converged from the circular cross section at the center, and formed into a bale shape in side view. I have. In the bobbin stone 1 according to this embodiment, a plurality of water passage grooves 10 are cut into the peripheral surface of the granular material by a water passage forming portion provided in an irregular shape on the inner periphery of the molding hole 22a of the mold 22. In addition, by providing a perforated portion in the forming hole 22a, an appropriate number of water passage holes 11 can be formed in the cross section of the granular material.

The manufacturing apparatus 2 configured as described above supplies the waste plastic 1P into the melting chamber 21 via the hopper 20,
This is melted while being sequentially stirred and fed to the molding chamber 23,
The melted waste plastic 1P is put into a molding die 22 in a molding chamber 23.
A linear material having a cross-sectional shape is extruded linearly (rod shape) from the molding hole 22a. Then, the linear material is cooled by the cooling device 2.
After being cooled to a soft state capable of being cut by the cutter 5, the cutters 26a on both sides of the cutting device 26 sequentially cut the scissors to a predetermined length. Thereby, the cobblestone 1 can be continuously manufactured into a bale-shaped granular material, and thereafter the cobblestone 1 becomes a completely hardened and stable state at room temperature, has compression resistance, and is stored in the storage device 7. Thus, it is used favorably for applications described below.

The cobblestone 1 manufactured by the above manufacturing method is as follows.
As shown in FIG. 3, a soft linear material is
By cutting the scissors at a and 26a, the both ends of the granular material are converged into a bale shape having a cross section smaller in diameter than the circular cross section at the center,
There is an advantage that the cutting can be performed uniformly and easily, and the linear material is cut in a soft state, so that the cutting load of the cutting device 26 can be reduced and the durability of the device can be improved. Further, as shown in FIGS. 3B and 3C, the waste stone 1P produced by the above-described manufacturing method is cured in a homogeneous state by stirring and dissolving the waste plastic 1P in which various materials are mixed. At the same time, a plurality of water passage grooves 10 or water passage holes 11 are simultaneously formed by simple means in the longitudinal direction of the surface or inside of the granular material.

Thus, when the bobble stone 1 is filled at the construction site described later, a gap can be appropriately formed between the stacked bobble stones 1 by the converged end of the granular material. As a result, water can be stored in this portion, and the water channel 10 or water hole 11 in which the water is formed in granular form is formed.
The fluid flows smoothly from one side to the other side to prevent clogging between the cobblestones 1 satisfactorily.
In addition, since the uneven surface area can be increased by the water passage holes 11 and the colonization habitability of the microorganisms can be enhanced, the promotion of the water purification action in the cobblestone layer can be favorably achieved in accordance with the function of the filling member. You can do it.

Accordingly, as will be described later with reference to FIGS. 4 and 5, the waste stone 1 using the waste plastic according to the present invention is filled with the waste stone 1 on the back surface of the retaining wall 3 constructed on the river. The structure of the purification device that enables the purification of river water can be easily configured by the formed cobblestone layer, and the cobblestone 1 is manufactured by using the waste plastic 1P. Since the weight can be extremely reduced as compared with natural stone or concrete crushed material, transportation and filling work can be efficiently and simply performed without involving heavy labor.

Further, according to the above-described manufacturing method, as shown in FIG. 2, by replacing the mold 22 of the manufacturing apparatus 2 with another mold 22 | Can be simultaneously manufactured, and the mixing and the mixing ratio thereof can be easily selected. That is, since the forming die 22 | is formed with forming holes 22a, such as polygonal, star-shaped, hook-shaped, etc. in cross section as shown in the figure, a linear material of these shapes is continuously extruded. Since the forming die 22 # has a plurality of forming holes 22a having the same shape and different diameters, a plurality of linear materials having different diameters can be extruded.

When it is desired to change the mixing ratio of a plurality of types of gang stones 1 produced by the respective forming dies 22 | or 22 #, the number of forming holes 22a should be increased or decreased, or a cutter 26a should be provided in each forming hole 22a. Is installed and the cutting timing is appropriately changed, so that several different types of gang stones 1 can be simultaneously and simply manufactured with a desired mixing ratio so as to be suitable for each construction site.

The gangue 1 thus mixed is
Is a manufacturing apparatus 2 in which a large bag capable of suspending the accommodation device 7 is used.
If it is made to be stored directly from the site, it can be efficiently stored in place using a transport machine such as a crane, and transport to the construction site can be performed easily and efficiently. In the case of the filling work, there is an advantage that the lower part of the bag 7 can be opened and discharged while being hung by the transporter, and the work can be performed easily.

The bobble stone 1 using the waste plastic produced as described above has a water passage groove 10 and a water passage hole 11
Any one of the above may be formed.
The cobblestone 1 may be melt-molded so as to generate open cells inside the granular material. In this case, the open cells further promote water flow from one side of the cobblestone 1 to the other side. And the ability to further promote the growth of microorganisms. Further, as shown in FIG. 3 (D), the cobblestone 1 may be formed in a state in which stones 6 such as pebbles, crushed stone or earth and sand are mixed in the inside of the granular material. Stone sands 6 may be embedded or adhered. In this case, the specific gravity of the cobblestone 1 is increased by the stone sands 6, so that waste plastic material can be saved or submerged in water. In addition, according to this manufacturing method, even waste plastic such as agricultural materials that are difficult to reuse or dirty waste plastic is simply melted and cut and molded. Since strict sorting can be omitted and processing can be performed efficiently, there is a feature that complicated problems in waste plastic processing can be solved.

Next, a method of using the above-mentioned cobblestone 1 will be described. FIG. 4 shows a conventional natural stone formed between concrete blocks 30 or stones stacked on each other, or between a vertical ground (filled portion) 3M at the back of a retaining wall 3 formed by a concrete wall or the like. An embodiment of filling and constructing the waste stone 1 according to the present invention instead of the waste stone material is shown. In this case, the water of the river is purified by the filled waste stone layer. That is, the retaining wall 3 in the illustrated example is formed by stacking the blocks 30 upward in an appropriate number of stages from the ground (river floor) 3K, and has a water passage hole 31 at a position near the river bottom having a normal water level H or lower. Blocks 30 are inserted at appropriate intervals, and blocks 30 having water holes 31 above them are inserted at appropriate intervals to perform retaining wall construction.

The cobblestone 1 is filled so as to fill at least the height range of the upper and lower water holes 31, 31 to form a water purifiable cobblestone layer, and above the cobblestone layer. The conventional cobblestones 1a are appropriately filled so as to be divided, so that the amount of the cobblestones 1 using the waste plastic can be appropriately saved. In this case, when the conglomerate layer made of the cobblestone 1 is surrounded by the sheet 32 having a small texture, the drainage water flow from the vertical ground 3M side is excellent while preventing the intrusion of small earth and sand into the cobblestone layer. Can be done.

The thus-filled cobblestone 1
Since the above-mentioned voids are appropriately formed in a homogenous state in the entire layer of the cobblestone layer between the adjacent cobblestones 1 and 1, it is possible to sufficiently store and pass water through the cobblestone layer. In addition to this, it is possible to promote water flow exchange between the cobblestone layer (backfill material) and river water through the water holes 31 formed in the retaining wall 3. Further, at this time, each of the cobblestones 1 prevents the clogging of the granular material in a favorable state while allowing microorganisms to adhere and settle in a suitable state by the water channel 10 or the water hole 11 of the same, and is directed from one side to the other side. Therefore, the present invention can provide a simple and inexpensive water purification structure using a cobblestone layer, which can smoothly purify rivers for a long period of time because of the smooth flow of water.

Next, a method of using the cobblestone 1 shown in FIG. 5 will be described. This retaining wall 3 is formed by stacking blocks 30 in the same manner as that of FIG. 4, and fish nest blocks 33 suitable for fish habitat are provided at predetermined intervals in the lower longitudinal direction on the back surface thereof. . On the back surface of the retaining wall 3, a cobblestone layer made of the above-mentioned cobble stone 1 is formed by a garbage mat 35 which can be attached and covered with the back surface of the retaining wall 3 in a predetermined range. That is, the gang stone mat 35 is formed by forming a mat-shaped gang stone layer by accommodating a large number of gang stones 1 in a net-shaped bag 35a of a predetermined width and length. Has the advantage that it can be handled as a unit that can be easily transported and can be easily arranged along the shape of the back surface of the retaining wall 3.

Next, referring to FIG. 6, a method of using the quarry stone 1 as a filling member of the culvert 4 will be described. In the illustrated culvert 4, a net-shaped sheet 40 is laid in a trench dug in the ground, and a gang stone 1 is thinly laid on the sheet 40, and then a mesh pipe 41 for water flow is passed through the central portion thereof. Next, the culvert 4 is constructed so as to surround the periphery of the culvert 4 so as to be completely wrapped with the sheet 40 while filling the pit 1 with the groove cross section, and backfill the outer periphery with soil. In the culvert 4 configured as described above, underground water and spring water smoothly pass through the gaps in the cobblestone layer formed by the cobblestone 1, the water channel 10 or the water hole 11 through the sheet 40. As a result, the underground water can be satisfactorily discharged toward the other side.

Therefore, the conventional culvert method using rice hulls as a filling member has the drawback that the rice husks are compressed and crushed by the earth pressure, thereby reducing the water drainage capacity at an early stage. The construction method using natural stone cobblestone as a member has drawbacks such as clogging at an early stage due to intrusion of earth and sand, but according to the culvert 4 of the present invention, these drawbacks can be favorably prevented. . In addition, since the natural stone is heavy, it is difficult to transport and construct it in a soft field, which causes problems such as making culvert work impossible. However, the stone 1 of the present invention is lightweight and significantly contaminates. Since there is no mixing of foreign substances, it is easy to pack the quarry stone in a bag and transport it by human power. Therefore, there are also advantages such as easy transport and construction.

Next, with reference to FIG. 7, a description will be given of a method of using the waste plastic to construct the block 1 into a block body 5 to facilitate installation in a river or sea. FIG. 1A shows a block body 5 formed by filling a quarry stone 1 into a net frame 5a made of a plastic material or a metal material. By arranging or laying a large number of the block bodies 5 on the river bottom or the river bank, it is possible to prevent erosion of the river and to appropriately perform water purification. In addition, boring stone 1
Since the block body 5 filled with is very light in weight as compared with the one filled with natural stone, construction can be performed efficiently and easily.

FIG. 3B shows a quarry stone 1 in a case 5b with a lid formed in a saw-like container made of concrete material.
Is filled to form the block body 5. In this case, it can be installed in a river in the same manner as described above and has the same advantages. In addition, it can be installed in the sea and used as a fishing reef. In addition, when performing this installation work, it is possible to simplify the work by installing a heavy-weight casing 5b first, filling the casing 5b with the lightweight rubble 1 and then closing the lid. Can be done. Further, the fishing reef formed by the block body 5 is characterized in that seaweed and the like and microorganisms are easily propagated in a large number of water passages 10 or water holes 11 formed in the cobblestone 1 and thus are suitable for fry rearing.

Next, another embodiment of the cobblestone 1 will be described. FIG. 8 is a cross-sectional view of the water-permeable groove 1 in which the cross section of
0 is formed, and a water channel 10 is opened therein to constitute the bobbin 1. According to this, a large valley-shaped water passage groove 10 is formed between the protrusions 12 projecting from the surface of the cobblestone 1, and the protrusion 12 and the water passage groove 10 are formed when the cobblestones 1 are stacked. Are meshed with each other and are stably laminated, and the large water passage groove 10 and the water passage hole 11 can improve the water permeability.

9 shows a granulated stone 1 in which the cross section of a granular material is formed in a polygonal shape and a plurality of large water holes 11 are opened therein. The bobbin stone 1 shown in FIG. 10 is one in which the cross section of the granular material is formed in a cylindrical shape, and a large number of water holes 11 are formed by providing an appropriate number of partition walls 13 inside. The cobblestone 1 shown in FIG. 11 is one in which the external shape of the granular material is manufactured by forming a frame in a tetrapod shape, and a plurality of water passage holes 11 are formed in an arbitrary direction. The cobblestone 1 configured as described above can be suitably used, for example, as a filling member for water storage buried in a rechargeable underground dam by forming it in a large size in addition to the above-described usage method. In addition, when the size of the cobblestone 1 is reduced, it can be suitably used also as a member installed in an aquarium for appreciation. is there.
