Description

Technology Field

[0001] The present invention relates to a blind culvert, and more specifically, to a standardized modular blind culvert. Background Technology

[0002] Blind culverts, which are widely employed as a subsoil drainage method during civil engineering and landscaping projects such as road construction, railways, sports fields, and lawn plazas, are a drainage technique designed to maintain or enhance the inherent usability of facilities by ensuring stability. This is achieved by draining groundwater contained within soil pores through guide pipes (e.g., perforated pipes), thereby preventing soil erosion, improving soil durability, and promoting plant growth.

[0003] In other words, as a gravity drainage method, it involves burying culverts to remove excess water contained in the subsoil layer; the culvert installation is performed by excavating down to the impermeable layer, burying permeable material, and then backfilling the top to drain the water contained in the subsoil.

[0004] The construction of a conventional blind culvert constructed in this manner is completed by excavating the surface layer to the depth indicated on the design drawings, laying down non-woven fabric, spreading aggregate or crushed stone, installing perforated pipes on the non-woven fabric, and then spreading aggregate or crushed stone again on top to form a permeable layer to fill the culvert. Finally, the culvert is wrapped with non-woven fabric and backfilled to create the surface layer.

[0005] In this case, the non-woven fabric functions as a filter to prevent soil particles from flowing in with water and clogging the perforated pipe due to soil conditions. Consequently, groundwater or water absorbed from the surface layer into the subsoil layer during rainfall passes through the non-woven fabric and the layer of crushed stone or aggregate, collects inside the pipe through the holes of the perforated pipe forming the drainage network, and is then drained through the pipe.

[0006] These conventional blind drainage facilities had a problem in that the amount of crushed stone or aggregate input could increase more than necessary because the materials used during excavation were not standardized (modular), leading to over-excavation.

[0007] In addition, there was a problem where stone dust was generated due to friction during the laying process of the crushed stone or aggregates, and if this dust absorbed water, it would harden over time, blocking the pores of the non-woven fabric and hindering proper drainage.

[0008] In addition, repairs are required when drainage is not smooth due to clogging of the non-woven fabric after long-term use. However, since conventional blind drainage facilities have non-woven fabric wrapped in crushed stone or aggregate, repairs require the inconvenience of having to remove the entire blind drainage facility to repair it, and in reality, there is a problem of having to rebuild the entire facility.

[0024] FIG. 1 is a drawing for explaining a modular blind culvert manufacturing system according to an embodiment of the present invention, FIG. 2 is a drawing showing the configuration of a waste synthetic resin aggregate manufacturing unit shown in FIG. 1, FIG. 3 is a perspective view showing a perforated pipe seated on a waste synthetic resin aggregate sheet, FIG. 4 is a perspective view showing a modular blind culvert manufactured through a modular blind culvert manufacturing system according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view of FIG. 4.

[0025] Referring to FIGS. 1 and 2, a modular blind drain manufacturing system according to one embodiment of the present invention may include a waste synthetic resin aggregate manufacturing unit (100), a waste synthetic resin aggregate sheet manufacturing unit (200), a pipe seating unit (300), an aggregate sheet banding unit (400), and a non-woven fabric packaging unit (500).

[0026] The waste synthetic resin aggregate manufacturing unit (100) can manufacture waste synthetic resin aggregate by crushing, washing, and dewatering the waste synthetic resin, then melting, compressing, and cutting it.

[0027] Referring to FIG. 2, in one embodiment, a waste synthetic resin aggregate manufacturing unit (100) may include a hopper (110), a transfer cylinder (120), an extrusion screw (130), a waste synthetic resin aggregate shape molding device (140), and an aggregate shape waste synthetic resin cooling tank (150).

[0028] The hopper (110) has a funnel-like shape that narrows toward the bottom, and crushed, washed, and dehydrated waste synthetic resin is fed into it.

[0029] The transfer cylinder (120) has a hopper (110) connected to one side and may have a transfer passage formed long in one direction with an open end. For example, the transfer cylinder (120) may be formed in a cylindrical shape.

[0030] The extrusion screw (130) is positioned along its length within the transfer cylinder (120) and melts and extrudes waste synthetic resin fed from the hopper (110) toward the end of the transfer cylinder (120).

[0031] The waste synthetic resin aggregate shape molding device (140) can be formed as a cylindrical metal mesh structure and arranged to surround the end of the transfer cylinder (120), so that molten waste synthetic resin discharged from the end of the transfer cylinder (120) is fed into it, and the fed waste synthetic resin can be molded into a random aggregate shape by allowing it to free-fall while passing through the openings of the metal mesh structure. In addition, the waste synthetic resin aggregate shape molding device (140) can be configured to rotate at a low speed. For example, a reduction gear and a motor can be connected to the cylindrical metal mesh to rotate it. As the cylindrical metal mesh rotates at a low speed, the waste synthetic resin passing through the cylindrical metal mesh can prevent the waste synthetic resin from accumulating in the openings of the mesh and clogging them due to repeated passage.

[0032] The aggregate-shaped waste synthetic resin cooling tank (150) is positioned at the bottom of the waste synthetic resin aggregate-shaped molding device (140), and cooling water is stored therein, so that the aggregate-shaped waste synthetic resin falling through the openings of the metal mesh structure is immersed in the cooling water and cooled.

[0033] The waste synthetic resin aggregate sheet manufacturing unit (200) manufactures a waste synthetic resin aggregate sheet filled with waste synthetic resin by filling the waste synthetic resin aggregate into a geotextile tube prepared in the form of a tube.

[0034] In one embodiment, a waste synthetic resin aggregate sheet manufacturing unit (200) may include a loading roller (201), a first geotextile mounting base (202), a geotextile cutter (203), a first sewing machine (204), a geotextile conveying roller (205), a first geotextile drop guide roller (206), a geotextile receiving pocket (207), a geotextile inlet opening device (208), an aggregate feeder (209), a second sewing machine (210), a second geotextile drop guide roller (211), a first conveyor (212), a second geotextile mounting base (213), and a sheet release device (214).

[0035] The loading roller (201) loads a geotextile tube (20) in one direction from a geotextile roll (30) which is provided with two sheets of geotextile stacked and wound into a tube shape with both longitudinal sides sewn.

[0036] The first geotextile mounting base (202) is in the form of a table and is positioned at the rear end of the geotextile loading roller, and a portion of the length of the geotextile tube (20) being loaded is mounted thereon.

[0037] The geotextile cutter (203) is positioned between the geotextile loading roller (201) and the first geotextile mounting base (202) and is configured to be vertically movable, and cuts the loaded geotextile tube (20) to a length that can be mounted on the first geotextile mounting base (202) while descending. For example, it can be cut to a length less than or equal to the total length of the first geotextile mounting base (202).

[0038] The first sewing machine (204) is positioned on the upper part of the first geotextile mounting base (202) so as to be located opposite the geotextile cutter (203), and sews one side short edge of the geotextile tube (20) along one side width direction of the geotextile tube (20) mounted on the first geotextile mounting base (202). For example, the first sewing machine (204) can sew the short edge of the geotextile tube (20) located opposite the geotextile cutter (203) (hereinafter referred to as the sewn lower end of the tube (20)), is normally spaced above the first geotextile mounting base (202), and can be lowered when sewing the geotextile tube (20).

[0039] The geotextile transfer roller (205) is positioned on the upper part of the first geotextile mounting base (202) between the geotextile cutting machine (203) and the first sewing machine (204), and is provided to be vertically movable. After one side of the geotextile tube (20) is sewn by the first sewing machine (204), it rotates and descends to push the geotextile tube (20) away from the first geotextile mounting base (202).

[0040] The first geotextile drop guide roller (206) is positioned lower than the first geotextile settling platform (202) at the rear end of the first geotextile settling platform (202) to support the geotextile tube (20) falling from the first geotextile settling platform (202). That is, it supports the geotextile tube (20) falling from the first geotextile settling platform (202) so that it enters the interior of the geotextile receiving pocket (207).

[0041] The geotextile receiving pocket (207) is spaced apart from the first geotextile drop guide roller (206) and accommodates the sewn lower direction of the falling geotextile tube (20), and is provided with a lower end that can be opened and closed. For example, the geotextile receiving pocket (207) is provided with a width that gradually decreases in the downward direction, and is provided with a sliding opening / closing door (2071) at the bottom, and the opening / closing door (2071) can be opened and closed by a cylinder.

[0042] The geotextile inlet opening device (208) is positioned horizontally spaced from the falling path of the geotextile tube (20) on both upper sides of the geotextile receiving pocket (207) and is provided to be horizontally movable, and moves forward to adsorb both sides of the geotextile tube (20), and then moves backward to open the unstitched top of the geotextile tube (20). For example, the geotextile inlet opening device (208) may include a pair of adsorption jigs (2082) equipped with an adsorption pad (2081) at the front end, and a pneumatic device may be connected to the pair of adsorption jigs (2082) to control the adsorption.

[0043] The aggregate feeder (209) is positioned above the geotextile inlet opening device (208) and can drop waste synthetic resin aggregate (10) manufactured in the waste synthetic resin aggregate manufacturing unit (100) into the geotextile tube (20) with the top open. For example, the aggregate feeder (209) may be provided in the form of a hopper with a lower part that can be opened and closed.

[0044] The second sewing machine (210) is positioned above the geotextile inlet opening device (208) and is configured to be horizontally movable. After waste synthetic resin aggregate (10) is fed into the geotextile tube (20), it advances to sew the open top of the geotextile tube (20), thereby completing the geotextile tube (20) into a waste synthetic resin aggregate sheet (1200) filled with waste synthetic resin aggregate (10). For example, the second sewing machine (210) may be configured to be positioned facing a sewing support plate (2101) placed on the opposite side, and to sew the open top of the geotextile tube (20) while pushing and supporting it against the sewing support plate (2101) as it advances.

[0045] The second geotextile drop guide roller (211) is positioned at the bottom of the geotextile receiving pocket (207) and can support the waste synthetic resin aggregate sheet (1200) that is dropped when the bottom of the geotextile receiving pocket (207) is open. That is, the second geotextile drop guide roller (211) can support the waste synthetic resin aggregate sheet (1200) to enter the first conveyor (212).

[0046] The first conveyor (212) is positioned at the rear end of the second geotextile drop guide roller (211) and transports the falling waste synthetic resin aggregate sheet (1200) in a direction away from the second geotextile drop guide roller (211). For example, the first conveyor (212) may be a roller conveyor or a belt conveyor.

[0047] The second geotextile mounting base (213) is in the form of a table and is positioned at the rear end of the first conveyor (212), and a waste synthetic resin aggregate sheet (1200) transported through the first conveyor (212) is mounted thereon.

[0048] The sheet removal device (214) is provided to be horizontally movable on the second geotextile mounting base (213) and pushes the waste synthetic resin aggregate sheet (1200) and the perforated pipe (1100) mounted thereon, which are mounted on the second geotextile mounting base (213), to remove them from the second geotextile mounting base (213). For example, the sheet removal device (214) may be arranged as a pair on the second geotextile mounting base (213) in the direction of the first conveyor (212), may include a sheet push plate (2141) and a cylinder (2142) that moves the sheet push plate (2141) forward and backward, and may be configured to be able to pop up from the inside of the second geotextile mounting base (213). In this case, when the waste synthetic resin aggregate sheet (1200) is placed on the second geotextile mounting base (213), it pops up to the upper surface of the second geotextile mounting base (213), and then the piston rod of the cylinder (2142) advances so that the sheet push plate (2141) can push the waste synthetic resin aggregate sheet (1200) on the second geotextile mounting base (213) to detach it.

[0049] The pipe mounting unit (300) mounts the perforated pipe (1100) onto the waste synthetic resin aggregate sheet (1200). That is, the pipe mounting unit (300) is configured to be positioned on the upper part of the second geotextile mounting base (213) to pick up the perforated pipe (1100) provided on one side and then mount it onto the waste synthetic resin aggregate sheet (1200) mounted on the second geotextile mounting base (213). For example, the pipe mounting unit (300) may be configured to be provided in the form of a robot arm to enable it to pick up the perforated pipe (1100).

[0050] The aggregate sheet banding unit (400) bands the waste synthetic resin aggregate sheet (1200) so that the waste synthetic resin aggregate sheet (1200), on which the perforated pipe (1100) is seated, wraps the perforated pipe (1100) in a circular manner. That is, the aggregate sheet banding unit (400) is positioned at the rear end of the second geotextile seating unit (213) and loads the waste synthetic resin aggregate sheet (1200) and perforated pipe (1100) that are detached through the geotextile detachment device (214), and bands the loaded waste synthetic resin aggregate sheet (1200) and perforated pipe (1100).

[0051] The nonwoven fabric packaging unit (500) can be configured to perform the task of wrapping the waste synthetic resin aggregate sheet, which has a perforated pipe wrapped in a circular shape, with nonwoven fabric.

[0052] In one embodiment, the nonwoven packaging unit (500) may include a sheet transfer robot (510) and a nonwoven packaging robot (520).

[0053] The sheet transfer robot (510) is positioned at the rear end of the aggregate sheet banding unit (400) and can pick up the banded waste synthetic resin aggregate sheet (1200) and perforated pipe (1100) and transfer them away from the aggregate sheet banding unit (400).

[0054] The nonwoven fabric packaging robot (520) is positioned at the rear end of the sheet transfer robot (510) and can pick up the nonwoven fabric tube (20) provided on one side, insert the waste synthetic resin aggregate sheet (1200) and perforated pipe (1100) that have been banded inside it, and then seal both ends of the nonwoven fabric tube (20).

[0055] A method for manufacturing a modular blind culvert using a modular blind culvert manufacturing system according to one embodiment of the present invention is as follows.

[0056] In the first step (S100), waste synthetic resin aggregate is manufactured and prepared.

[0057] That is, through the waste synthetic resin aggregate manufacturing unit (100), the waste synthetic resin that has been crushed, washed, and dehydrated is fed into the hopper (110) and supplied to the transfer passage inside the transfer cylinder (120), and then the extrusion screw (130) is rotated to melt and extrude the waste synthetic resin toward the end of the transfer passage. Then, the melted waste synthetic resin at the end of the transfer passage is fed into the metal mesh structure of the aggregate shape molding device (140) and free-falls while passing through the openings of the metal mesh structure, and then the free-falling waste synthetic resin is fed into and submerged in the waste synthetic resin cooling tank (150) to cool, thereby manufacturing the waste synthetic resin aggregate.

[0058] In the second step (S120), the geotextile tube (20) is unwound and loaded from the geotextile roll (30) in one direction. At this time, the geotextile tube (20) has two long axis sides parallel to its length direction sewn together.

[0059] In the third step (S130), the geotextile tube (20) is placed horizontally with one side open. That is, the loaded geotextile tube (20) is supported by the geotextile loading roller (201) and loaded toward the first geotextile mounting base (202). At this time, the geotextile cutter (203) descends to cut the geotextile tube (20) to a certain length, and the cut geotextile tube (20) is placed on the first geotextile mounting base (202). Then, the first sewing machine (204) descends to sew and seal the short side of the geotextile tube (20) located on the opposite side of the geotextile cutter (203).

[0060] In the fourth step (S140), the horizontally placed geotextile tube (20) is set up so that the opening direction is facing upward.

[0061] That is, the geotextile tube (20) placed on the first geotextile mounting base (202) is pushed away from the first geotextile mounting base (202) by the geotextile transfer roller (205) rotating and descending, and then the geotextile tube (20) is supported by the first geotextile drop guide roller (206) and enters the interior of the geotextile receiving pocket (207), so that the geotextile tube (20) is set up with the open top facing upward.

[0062] In the fifth step (S150), waste synthetic resin aggregate is filled into the inside of the geotextile tube (20).

[0063] That is, a pair of suction jigs (2082) of the geotextile inlet opening device (208) suction both sides of the geotextile tube (20) and then move backward to open the top of the geotextile tube (20), and then drop the recycled synthetic resin aggregate (10) from the top of the geotextile tube (20) into the geotextile tube (20) through the aggregate feeder (209).

[0064] In step 6 (S160), the open top of the geotextile tube (20) is sealed.

[0065] That is, the second sewing machine (210) moves horizontally toward the geotextile tube (20) and sews and seals the top of the geotextile tube (20). At this time, the waste synthetic resin aggregate sheet (1200) filled with waste synthetic resin aggregate (10) is completed.

[0066] In step 7 (S170), the waste synthetic resin aggregate sheet (1200) is arranged horizontally.

[0067] That is, the bottom of the geotextile receiving pocket (207) is opened so that the waste synthetic resin aggregate sheet (1200) falls, and the falling waste synthetic resin aggregate sheet (1200) is supported by the second geotextile drop guide roller (211) and moves toward the first conveyor (212), and the first conveyor (212) transports the waste synthetic resin aggregate sheet (1200) toward the second geotextile settling platform (213), and the transported waste synthetic resin aggregate sheet (1200) is placed on the second geotextile settling platform (213) and laid horizontally.

[0068] In step 8 (S180), the perforated pipe (1100) is placed on the waste synthetic resin aggregate sheet (1200).

[0069] That is, the pipe mounting unit (300) mounts the perforated pipe (1100) as shown in FIG. 3 on a waste synthetic resin aggregate sheet (1200) placed horizontally on the second geotextile mounting base (213).

[0070] In step 9 (S190), the waste synthetic resin aggregate sheet (1200) is banded so that the waste synthetic resin aggregate sheet (1200) wraps around the perforated pipe (1100) in a circular shape.

[0071] That is, the sheet detachment device (214) advances to push the waste synthetic resin aggregate sheet (1200) placed on the second geotextile mounting base (213) and the perforated pipe (1100) mounted thereon, thereby detaching the waste synthetic resin aggregate sheet (1200) and the perforated pipe (1100) from the second geotextile mounting base (213), and the detached waste synthetic resin aggregate sheet (1200) and perforated pipe (1100) are supplied onto the aggregate sheet banding unit (400), and then the aggregate sheet banding unit (400) is driven to band the waste synthetic resin aggregate sheet (1200) and the perforated pipe (1100).

[0072] In step 10 (S200), the waste synthetic resin aggregate sheet (1200) and the perforated pipe (1100) are wrapped with a non-woven fabric (1300).

[0073] That is, the sheet transfer robot (510) picks up the banded waste synthetic resin aggregate sheet (1200) and the perforated pipe (1100) and transfers them toward the non-woven fabric packaging robot (520), and the non-woven fabric packaging robot (520) picks up the non-woven fabric tube (20) provided on one side, inserts the banded waste synthetic resin aggregate sheet (1200) and the perforated pipe (1100) into it, and then seals one end of the non-woven fabric tube (20).

[0074] Once this process is completed, the manufacturing of the modular blind culvert (1000) is completed as shown in FIGS. 4 and FIGS. 5.

[0075] The manufactured modular blind culvert (1000) has a structure in which a perforated pipe (1100) is wrapped by a waste synthetic resin aggregate sheet (1200) filled with waste synthetic resin aggregate (10), and the perforated pipe (1100) and the waste synthetic resin aggregate sheet (1200) are wrapped by a non-woven fabric (1300) with a mesh structure. At this time, a portion of one end of the non-woven fabric (1300) wraps around the circumference of the perforated pipe (1100) and is fixed, and can be finished by extending a certain length from the perforated pipe (1100). For example, the finishing of one side of the non-woven fabric (1300) may be done by heat fusion or banding.

[0076] The perforated pipe (1100) may have a double pipe structure as shown in FIG. 4 or a bundle pipe structure. The bundle pipe may be an S-shaped bundle pipe. The S-shaped bundle pipe is a structure in which S-shaped cross-sections are connected in bundles, and a number of linear collection ports and linear drainage ports are interconnected, so it can exhibit excellent collection and drainage effects.

[0077] Compared to conventional blind culvert facilities constructed by laying non-woven fabric and filling with crushed stone, the modular blind culvert (1000) manufactured by the modular blind culvert manufacturing system according to one embodiment of the present invention can simply be constructed by inserting the modular blind culvert (1000) after excavation, thereby greatly simplifying the construction of the blind culvert facility and increasing the speed of construction.

[0078] In addition, since no stone dust is generated due to friction of aggregates such as crushed stone or recycled concrete introduced in conventional blind drainage facilities, the clogging of the nonwoven fabric (1300) can be resolved, which has the advantage of improving drainage performance.

[0079] In addition, when constructing a blind culvert facility using a modular blind culvert (1000), the excavation specifications of the blind culvert facility can be standardized, so there is no need for excessive excavation, and the amount of aggregate input can also be standardized.

[0080] In addition, when the waste synthetic resin aggregate sheet (1200) and non-woven fabric (1300) are damaged and repair is required after the modular blind culvert (1000) is installed in a railway rail side ditch or golf course, only the waste synthetic resin aggregate sheet (1200) and non-woven fabric (1300) can be replaced, so there is no need to repair the entire blind culvert facility, which has the advantage of making maintenance of the blind culvert facility easy.

[0081] FIG. 6 is a perspective view illustrating a modular blind culvert according to another embodiment of the present invention, and FIG. 7 is a cross-sectional view showing a waste synthetic resin aggregate sheet shown in FIG. 6 wrapping a perforated pipe in a circular shape.

[0082] Referring to FIGS. 6 and 7, in a modular blind culvert according to another embodiment of the present invention, a wing portion (1210) may be formed on one side in the longitudinal direction of a waste synthetic resin aggregate sheet (1200) of the modular blind culvert (1000), and the wing portion (1210) may cover two corresponding ends (1200a, 1200b) when the waste synthetic resin aggregate sheet (1200) wraps around a perforated pipe (1100). For example, the wing portion (1210) may be provided by being sewn to one side of the waste synthetic resin aggregate sheet (1200).

[0083] In this modular blind culvert (1000) according to another embodiment of the present invention, when a waste synthetic resin aggregate sheet (1200) wraps around a perforated pipe (1100), the wing portion (1210) covers the two corresponding ends (1200a, 1200b) to prevent lifting of the two ends (1200a, 1200b) or to prevent the introduction of foreign substances.

[0084] Meanwhile, according to another embodiment of the present invention, an adhesion reinforcing agent may be applied to one side of a portion of the end direction of the nonwoven fabric (1300), that is, a portion of the portion fixed to wrap around the perforated pipe (1100), in order to improve adhesion with the perforated pipe (1100).

[0085] The adhesion enhancer may comprise 67 parts by weight of water, 13 parts by weight of dodecyl acrylate, 12 parts by weight of 1-benzyl-2-methylimidizol, 5 parts by weight of ammonium persulfate, and 3 parts by weight of sodium bicarbonate.

[0086] Dodecyl acrylate and 1-benzyl-2-methylimidizol play roles such as adhesion, imparting adhesion, and promoting curing, ammonium persulfate acts as a catalyst, and sodium bicarbonate acts as a buffer.

[0087] The reason for limiting the constituent materials and components and the numerical values ​​of the mixing ratio as described above is that, based on the analysis of test results after repeated failures by the inventor, the optimal effect was achieved at the aforementioned limited compositional components and numerical ratios.

[0088] Additionally, the perforated pipe (1100) may be made of a synthetic resin material, and the raw material content ratio of the perforated pipe (1100) is a mixture of 64% by weight of synthetic resin, 14% by weight of dithio dimorpholine, 6% by weight of barium stearate, 8% by weight of carbon black, and 8% by weight of 3C (N-PHENYL-N'-ISOPROPYL- P-PHENYLENEDIAMINE).

[0089] Dithio dimorpholine is added to promote vulcanization, barium stearate is added to act as a softener, carbon black is added to increase or improve wear resistance, thermal conductivity, etc., and 3C (N-PHENYL-N'-ISOPROPYL- P-PHENYLENEDIAMINE) is added as an antioxidant.

[0090] Accordingly, the present invention increases the elasticity, toughness, and rigidity of the perforated pipe (1100), thereby improving durability and weather resistance, and consequently, the lifespan of the perforated pipe (1100) is increased.

[0091] The synthetic resin material has a hardness (Shore A) of 63 and a tensile strength of 150 kg / cm².

[0092] The reason for limiting the rubber material constituent substances and components, as well as the numerical values ​​of the mixing ratios, is that the inventors, after analyzing test results following repeated failures, found that the optimal effect was achieved at the aforementioned limited compositional components and numerical ratios.
