Reinforcement Structure Of Utility Pole

Abstract

The present invention relates to a reinforcing structure for a utility pole, comprising a reinforcing stent inserted into the internal space of the utility pole, and a reinforcing agent injected into the internal space of the utility pole, adhering to the inner surface of the utility pole and embedding and fixing the reinforcing stent. As the reinforcing stent expands within the internal space of the utility pole and is positioned along the inner surface of the utility pole, it is possible to reinforce not only the entire utility pole but also partial reinforcement, and the utility pole can be reinforced in a short time without replacing the utility pole. Furthermore, based on the location of rebar fracture, the vertical load strength, horizontal load strength, and breaking load strength can be reinforced, and the occurrence of cracks can be prevented.

Description

Technology Field

[0001] The present invention relates to a utility pole reinforcement structure that partially or completely reinforces a damaged or cracked utility pole. Background Technology

[0002] A utility pole, also known as a power pole or utility pole, is a column erected to support power lines or communication cables, and is primarily made of steel pipe or concrete.

[0003] The utility pole has a structure in which reinforcing bars are evenly distributed along the circumference of the cross-section of the utility pole, and the reinforcing bars are configured to apply a predetermined tensile force before forming the utility pole and release the tensile force after the concrete is cured so that prestress is applied.

[0004] The guy wire is provided with galvanized steel wire, etc., to connect the pole and the ground, reinforce strength so that the pole can be upright, and maintain equilibrium against unbalanced loads.

[0005] Recently, there has been a trend to gradually increase the strength of concrete poles to ensure the stability of processing facilities, such as by applying ultra-high-strength pole production to standard poles.

[0006] However, facility safety accidents such as pole breakage and tipping are increasing due to reasons including reduced durability caused by the aging of existing poles, loads from heavy power equipment, the installation of communication lines by telecommunication operators, and external impacts.

[0007] The causes of failure of utility poles include the application of constant stress due to uneven loading, moisture penetration due to environmental factors, and the characteristics of reinforcing steel materials, such as corrosion caused by reaction with moisture.

[0008] Furthermore, when carrying out work to replace aging or defective utility poles, there is a problem in that significant costs and time are required, as it necessitates not only the cost of replacing the poles but also the replacement of related auxiliary equipment, such as wires, pole poles, insulators, switches, and transformers.

[0009] As a method to reinforce broken utility poles, the ‘reinforcement method using aramid fibers’ is a method of construction that repairs external cracks in the utility pole, but it is difficult to apply when it is difficult to increase the tensile strength of the utility pole itself and when there is a concern about rebar fracture and rebar corrosion.

[0019] The above second reinforcing agent is characterized by being cast in the form of a hollow cylinder, including the reinforcing stent.

[0020] The above second reinforcing agent is characterized by being partially poured into a reinforcing section that includes the upper and lower parts at a certain distance from the point of damage of the above pole.

[0035] FIG. 1 is a diagram showing a pole structure according to one embodiment of the present invention.

[0036] The pole (1) forms a vertically long structure. The pole (1) can be made of steel pipe or concrete.

[0037] The utility pole (1) is configured such that part is buried and fixed in the lower part of the ground (12), and part is exposed above ground so that power lines or communication lines can be stretched and hung.

[0038] According to the specified specifications, the utility pole (1) may be configured with an upper end diameter of 190 mm and a lower bottom diameter of 323 to 403 mm. The utility pole (1) is configured with a hollow structure in which the diameter increases in a 1 / 75 ratio toward the bottom, so that the inner diameter of the upper part of the utility pole is 90 mm or more and the inner diameter of the bottom is 263 mm, forming a space inside.

[0039] The top part of the pole (1) can be constructed with lightweight concrete mortar.

[0040] The pole reinforcement structure of the present invention may include a reinforcing stent (3) inserted into the internal space of the pole (1) and a reinforcing agent.

[0041] A reinforcing structure for a utility pole can be formed by removing the mortar sealing section (P1) at the top of the utility pole (1) and then injecting a reinforcing stent (3) and a reinforcing agent into the internal space of the hollow structure.

[0042] The reinforcing stent (3) and reinforcing agent can be used for full or partial reinforcement of the pole (1).

[0043] FIG. 2 is a cross-sectional view showing a pole reinforcement structure for reinforcing the entire pole according to one embodiment of the present invention.

[0044] As shown in FIG. 2(a), the utility pole (1) includes a main body (2) having a circular cross-section, and a circular space is formed inside.

[0045] The reinforcing stent (3) is inserted into the internal space of the pole (1) by the reinforcing material installation device (30) (S10). The reinforcing stent (3) may include a plurality of reinforcing steel bars (4) and a plurality of steel wire mesh stents (5).

[0046] The reinforcing stance (3) is inserted into the internal space of the utility pole (1) in a form where a plurality of reinforcing steel bars (4) and a plurality of steel wire mesh stances (5) are densely packed in the central part. As previously described, an expandable reinforcing stance (3) may be used as the reinforcing stance (3). The expandable reinforcing stance (3) may be formed as an expandable string structure.

[0047] The reinforcing stance (3) can maintain a dense state in which reinforcing steel bars (4) and steel wire mesh stances (5) are formed by a separate cover or a force acting from the outside.

[0048] As shown in Fig. 2(b), the reinforcing stent (3) is expanded after being inserted into the pole (1) (S20).

[0049] The reinforcing stance (3) can be extended from the center outwardly toward the inner surface of the utility pole (1) by a plurality of reinforcing steel bars (4) and a plurality of steel wire mesh stances (5).

[0050] The reinforcing stance (3) can be positioned to be in contact with the inner surface of the utility pole (1). Additionally, the reinforcing stance (3) can be positioned so that the reinforcing steel bar (4) and the steel wire mesh stance (5) are close to the inner surface of the utility pole (1).

[0051] The reinforcing stance (3) can be arranged in a circular shape by the expanding force of the reinforcing bar (4) and the steel wire mesh stance (5). The reinforcing stance (3) can have the reinforcing bar (4) and the steel wire mesh stance (5) arranged in an intersecting manner.

[0052] A reinforcing bar (4) may be placed in the center. Depending on the case, additional reinforcing bars may be added to the center.

[0053] The reinforcing stent (3) is arranged in a circular shape inside the pole (1) to prevent cracks from forming in the pole. The reinforcing stent (3) can reinforce strength against maximum vertical load, horizontal load, and breaking load.

[0054] In addition, the reinforcing stance (3) can be used for full reinforcement and partial reinforcement of the pole (1).

[0055] As shown in Fig. 2(c), a first reinforcing agent (6) is introduced into the internal space of the pole (1) in which the reinforcing stent (3) is installed (S30).

[0056] The first reinforcing agent (6) can be injected into the internal space of the pole (1) by a reinforcing agent injection device. The first reinforcing agent (6) is used for reinforcing the entire pole, and a mixture of Portland cement and plywood can be used.

[0057] The first reinforcing member (6) is in close contact with the inner surface of the pole (1) and embeds the reinforcing stent (3).

[0058] The first reinforcing member (6) is embedded including the reinforcing stent (3) and fixes the reinforcing stent (3). The first reinforcing member (6) embeds the internal space of the utility pole (1).

[0059] The first reinforcing agent (6) can reinforce the strength of the pole (1) through a curing process.

[0060] The first reinforcing agent (6) can reinforce the strength, water resistance, and freeze-thaw resistance of the pole (1).

[0061] FIG. 3 is a cross-sectional view illustrating another planned price of a pole reinforcement structure according to one embodiment of the present invention.

[0062] As shown in FIG. 3(a), the reinforcing stent (3) is inserted into the internal space of the pole (1) by the reinforcing material installation device (30) (S40).

[0063] The reinforcing stance (3) may include a plurality of reinforcing bars (4) and a plurality of steel wire mesh stances (5). The reinforcing stance (3) is inserted into the internal space of the utility pole (1) in a form where the plurality of reinforcing bars (4) and the plurality of steel wire mesh stances (5) are densely packed in the central part.

[0064] As previously described, the reinforcing stance (3) may be an expandable reinforcing stance (3). The expandable reinforcing stance (3) may be formed into an expandable string structure.

[0065] As shown in Fig. 3(b), the reinforcing stent (3) is expanded after being inserted into the pole (1) (S50).

[0066] The reinforcing stance (3) can have a plurality of reinforcing bars (4) and a plurality of steel wire mesh stances (5) extended outwardly with respect to the center point.

[0067] The reinforcing stance (3) can be positioned to be in contact with the inner surface of the utility pole (1). Additionally, the reinforcing stance (3) can be positioned so that the reinforcing steel bar (4) and the steel wire mesh stance (5) are close to the inner surface of the utility pole (1).

[0068] The reinforcing stance (3) may be arranged in a circular shape, with reinforcing steel bars (4) and steel wire mesh stances (5) arranged in an alternating pattern.

[0069] At this time, the reinforcing stent (3) does not include a central reinforcing bar.

[0070] The reinforcing stent (3) is arranged in a circular shape inside the pole (1) to prevent cracks from occurring in the pole. The reinforcing stent (3) can reinforce strength against maximum vertical load, horizontal load, and breaking load.

[0071] In addition, the reinforcing stance (3) can be used for partial reinforcement.

[0072] As shown in Fig. 3(c), the second reinforcing agent (7) can be introduced into the internal space of the pole (1) where the reinforcing stent (3) is installed (S60).

[0073] The second reinforcing member (7) may not completely fill the internal space of the pole (1), but may be injected based on the location where the reinforcing stent (3) is installed, and may be formed in the shape of a circular ring. The second reinforcing member (7) may be formed in the shape of a hollow cylinder including the reinforcing stent (3).

[0074] The second reinforcing agent (7) can be sprayed at the location where the reinforcing stent (3) is installed through the shotcrete spraying device (60).

[0075] The second reinforcing agent (7) can be rotated and sprayed by a shotcrete spraying device (60).

[0076] The second reinforcing agent (7) can be poured by spraying it through a shotcrete spraying device (60) into a section (P3-P4) that requires reinforcement, as shown in Fig. 7 which will be explained later.

[0077] The second reinforcing member (7) can be cast in the form of a hollow cylinder. The second reinforcing member (7) can be attached to the inner surface of the utility pole (1) with the reinforcing stent (3) inside, thereby fixing the reinforcing stent (3).

[0078] As the second reinforcing agent (7) is partially poured, rapid pouring and curing are possible.

[0079] Shotcrete can be used as the second reinforcing agent (7). Shotcrete is a type of mortar made by blowing cement, coarse aggregate, and water with compressed air. It can be injected into small gaps, adheres easily to the construction surface, and has high density and strength.

[0080] The shotcrete spraying device (60) can be used for partial reinforcement of the pole (1).

[0081] As described above, when partial reinforcement is performed, a circular space remains inside, so if additional reinforcement is required, additional reinforcement work can be performed by inserting devices such as a reinforcement installation device (30), a reinforcement injection device (40), and a shotcrete spraying device (60) through the remaining space.

[0082] When partially reinforcing, the reinforcing stance (3) is inserted into the interior of the utility pole (1) through the reinforcing material installation device (30) while the reinforcing steel bar (4) and the steel wire mesh stance (5) are densely packed by a separate cover or external force.

[0083] FIG. 4 is a flowchart illustrating a method for reinforcing a utility pole according to one embodiment of the present invention.

[0084] As shown in FIG. 4, the post-pressing device makes a hole in the top of the utility pole (1) and removes the construction part of the utility pole (1) (S310). Accordingly, a hole is formed in the top of the utility pole (1), and the internal space (13) is exposed to the outside.

[0085] The reinforcing material installation device (30) is inserted into the internal space (13) of the utility pole (1), and the reinforcing stent (3) is installed by inserting it into the internal space of the utility pole (1) (S310).

[0086] At this time, the reinforcement method is determined by distinguishing between full reinforcement and partial reinforcement of the entire pole (1) (S320).

[0087] When reinforcing the entire pole (1), the reinforcing material installation device (30) moves the injection port to the lower bottom end (11) of the pole (1), and then installs the reinforcing stent (3) by inserting it from the bottom end (11) of the pole (1) (S335).

[0088] The reinforcing material installation device (30) inserts and installs the reinforcing stent (3) while moving the injection port upward at a predetermined speed. The reinforcing stent (3) can be installed from the bottom (11) to the top of the utility pole (1).

[0089] After being inserted into the interior of the utility pole (1), the reinforcing stent (3) can be expanded and arranged in a circular manner in contact with or adjacent to the inner surface of the utility pole (1) (S345). That is, the reinforcing stent (3) is inserted into the interior of the utility pole (1) in a dense state by a separate cover or a force acting from the outside, and after insertion, as the force acting from the cover or the outside is removed, it can be expanded from the center to the outside.

[0090] The reinforcing stance (3) includes a plurality of reinforcing bars (4) and a plurality of steel wire mesh stances (5). The reinforcing stance (3) is an expandable reinforcing stance (3) and can be formed as an expandable string structure. Since the reinforcing stance (3) expands from the center outward, a plurality of reinforcing bars (4) and a plurality of steel wire mesh stances (5) can be arranged in an intersecting manner along the inner surface of the utility pole (1).

[0091] When the reinforcing stent (3) is placed, the reinforcing material installation device (30) is removed from the pole (1), and the reinforcing material injection device (40) is inserted and installed inside the pole (1).

[0092] After the injection port of the reinforcing agent injection device (40) moves to the bottom end (11), the first reinforcing agent (6) is injected into the internal space of the pole (1) (S350).

[0093] The injection port of the reinforcing agent injection device (40) moves upward at a predetermined speed and injects the first reinforcing agent (6) into the internal space of the utility pole (1). Accordingly, the first reinforcing agent (6) fills the internal space of the utility pole (1).

[0094] The first reinforcing agent (6) is injected from the bottom (11) to the top of the pole (1). The reinforcing stent (3) is embedded by the first reinforcing agent (6).

[0095] The first reinforcing agent (6) undergoes a curing process.

[0096] Meanwhile, when partially reinforcing the pole (1), the reinforcing material installation device (30) moves to the reinforcement section and then inserts and installs the reinforcing stent (3) in the reinforcement section (S331).

[0097] The reinforcement section can be set to include the upper and lower parts over a certain distance from the point requiring reinforcement. For example, as shown in FIG. 7, the third point (P3) to the fourth point (P4) can be set as the reinforcement section based on the damaged point (P2).

[0098] After being inserted into the reinforcing section inside the utility pole (1), the reinforcing stent (3) can be expanded and arranged in a circular manner at a position that is in contact with or adjacent to the inner surface of the utility pole (1) (S341). In the reinforcing stent (3), a plurality of reinforcing steel bars (4) and a plurality of steel wire mesh stents (5) can be arranged in a circular manner along the inner surface of the utility pole (1).

[0099] When the installation of the reinforcing stent (3) is completed, the reinforcing installation device (30) is removed from the pole (1), and the shotcrete spraying device (60) is installed.

[0100] The shotcrete spraying device (60) sprays the second reinforcing agent (7) at the location where the reinforcing stent (3) is installed while rotating after the spray nozzle moves to the reinforcing section (S360).

[0101] Shotcrete may be used for the second reinforcing agent (7). The second reinforcing agent (7) may be poured into the reinforcing stent (3) to form a circular column. The second reinforcing agent (7) may be poured in the form of a hollow cylinder with a space formed in the center.

[0102] The second reinforcing agent (7) is sprayed over an area larger than the reinforcing stent (3) and may contain the reinforcing stent (3) inside. The second reinforcing agent (7) may be in close contact with the inner surface of the utility pole (1) to fix the reinforcing stent (3).

[0103] Once the pouring of the first reinforcing agent (6) or the second reinforcing agent (7) is completed, a leveling process is performed.

[0104] Once the curing process is complete, lightweight concrete mortar sealing is performed on the uppermost part of the utility pole (S370).

[0105] Therefore, the strength of the pole (1) can be reinforced by a reinforcing stent (3) and a reinforcing agent (first reinforcing agent (6) or second reinforcing agent (7)).

[0106] The pole (1) can prevent cracks from occurring in the pole through the reinforcing stance (3) of the reinforcing structure, and its strength against maximum vertical load, horizontal load, and breaking load can be reinforced. In addition, the strength, water resistance, and freeze-thaw resistance of the pole (1) can be reinforced by the first reinforcing agent (6) or the second reinforcing agent (7).

[0107] FIGS. 5 and 6 are reference drawings for explaining a method of reinforcing an entire pole according to an embodiment of the present invention.

[0108] As shown in FIG. 5 (a), when the mortar construction part (P1) at the top of the pole (1) is removed, the reinforcing installation device (30) inserts the injection port into the interior of the pole (1) and inserts the reinforcing stent (3) from the bottom end (11) of the pole (1).

[0109] The reinforcing stance (3) may include a plurality of reinforcing bars (4) and a plurality of steel wire mesh stances (5).

[0110] As shown in FIG. 5(b), the reinforcing stent (3) extends from the interior of the pole (1) and is arranged in a circular shape along the inner surface of the pole (1).

[0111] The reinforcing stance (3) may be positioned in a location adjacent to or in contact with the inner surface of the utility pole (1) by extending a plurality of reinforcing bars (4) and a plurality of steel wire mesh stances (5) outwardly. The reinforcing bars (4) and steel wire mesh stances (5) are arranged in an intersecting manner.

[0112] As shown in Fig. 5(c), the reinforcing installation device (30) inserts the reinforcing stent (3) as the injection port moves upward.

[0113] The reinforcing material installation device (30) can install a reinforcing stent (3) up to the top of the utility pole (1). The reinforcing material installation device (30) is released from installation, leaving a certain space at the top.

[0114] As shown in FIG. 6 (a), with the reinforcing stent (3) installed in the internal space of the utility pole (1), the reinforcing injection device (40) is injected into the interior.

[0115] The reinforcing agent injection device (40) injects the first reinforcing agent (6) from the bottom end (11) of the pole (1).

[0116] As shown in FIG. 6(b), the reinforcing agent injection device (40) can inject the first reinforcing agent (6) as the injection port moves upward.

[0117] The first reinforcing member (6) includes a reinforcing stent (3) and fills the internal space of the pole (1).

[0118] As shown in Fig. 6 (c), the first reinforcing member (6) buries the reinforcing stent (3) and buries the internal space of the pole (1), leaving some space at the top.

[0119] Once the curing of the first reinforcing agent (6) is complete, mortar construction (14) is performed on the uppermost part of the pole (1) using lightweight concrete.

[0120] Accordingly, the strength of the pole (1) is reinforced by the reinforcing stent (3) and the first reinforcing material (6). A reinforcing bar (4) may be placed in the center. In some cases, additional reinforcing bars may be added to the center.

[0121] FIG. 7 is a figure referenced to explain a pole reinforcement method for reinforcing a portion of a pole according to an embodiment of the present invention.

[0122] As shown in FIG. 7, the reinforcing stent (3) can be introduced into the internal space (13) through the upper hole that is exposed after the mortar sealing portion of the pole (1) is removed.

[0123] The reinforcing stent (3) can be inserted into the internal space of the pole (1) through the reinforcing material installation device (30).

[0124] When partially reinforcing a utility pole (1), the reinforcing stent (3) and the second reinforcing agent (7) are introduced into a certain reinforcing section based on the point of failure or damage (P2), thereby partially reinforcing the utility pole (1).

[0125] The reinforcing stance (3) and the second reinforcing material can be introduced into the reinforcing section (P3-P4) from a point (P3) a certain distance below the point (P2) to a point (P4) a certain distance above it. The reinforcing stance (3) and the second reinforcing material are introduced into an area larger than the area of ​​the point (P2) to partially reinforce the pole (1).

[0126] The reinforcing stent (3) can be inserted into the internal space of the utility pole (1) and then expanded to be in contact with or adjacent to the inner surface of the utility pole (1).

[0127] The reinforcing stance (3) can be extended and arranged in a circular shape based on the inner surface of the pole (1).

[0128] The second reinforcing agent (7) can be injected after the reinforcing stent (3) is installed. The second reinforcing agent (7) can be sprayed into the reinforcing section where the reinforcing stent (3) is installed.

[0129] The second reinforcing agent (7) is rotated and sprayed into the interior of the pole (1) through a shotcrete spraying device (60).

[0130] The second reinforcing agent (7) can be attached to the inner surface of the pole (1) to fix the reinforcing stance (3). The second reinforcing agent (7) can be injected over a wider area than the reinforcing stance (3) so that the reinforcing stance (3) is buried.

[0131] The second reinforcing member (7) is not filled in the entire internal space of the pole (1), but is injected based on the location where the reinforcing stent (3) is installed, and can be formed in the shape of a hollow cylinder.

[0132] Even if the second reinforcing agent (7) is poured, a circular space is formed inside, so other parts of the pole (1) can be further reinforced later.

[0133] Accordingly, a pole reinforcement structure according to one aspect of the present invention can reinforce strength against vertical loads, horizontal loads, and failure loads using a reinforcing stent, and can reinforce the entire structure using a first reinforcing agent or reinforce strength, water resistance, and freeze-thaw resistance including damaged parts using a second reinforcing agent. In addition, the present invention can rapidly perform full reinforcement or partial reinforcement.

[0134] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the claims below. Explanation of the symbols
