More specifically, the thread portion formed for scaffold bolt fastening is enlarged by a dedicated drill bit, but only the plastic portion corresponding to the scaffold bolt hole is enlarged, thereby minimizing the vibration and impact received by the utility pole and helping to improve the working speed and safety of the operator who supplies the injection. The present invention relates to a utility pole reinforcement method for supplying an injection into the interior of a utility pole for reinforcing the utility pole having a scaffold bolt hole.

Background Art

[0002] A utility pole is a vertical structure for supporting electric wires or communication lines above a certain height from the ground. It is manufactured by arranging steel bars in a circular shape, making a formwork for a circular cylinder, placing concrete, and rotating the circular formwork so as to have a hollow shape, that is, an empty space inside.

[0003] The utility pole manufactured as described above is installed by excavating the ground to a certain depth to form a hole, then burying the lower part of the utility pole, usually about 2 m, and placing concrete.

[0004] In addition, many accessories such as power lines, communication lines, insulators, lightning arresters, primary side switches of transformers, and pole-mounted transformers are attached to the upper part of the utility pole.

[0005] After such a utility pole is installed, due to the aging of the concrete and the reduction of durability due to hollow molding, it cannot withstand the load of the accessories attached to the upper part and the impact from the outside, and there have been many cases where the utility pole has fallen.

[0006] When the utility pole falls during the installation and use of the utility pole as described above, many accessories such as power lines, communication lines, insulators, lightning arresters, primary side switches of transformers, and pole-mounted transformers attached to the upper part of the utility pole are damaged. In particular, there are many problems such as personal accidents due to high-voltage current and damages due to power outages.

[0007] Specifically, with conventional concrete utility poles, the workers varied depending on the installation location and duration, resulting in differences in skill levels. Therefore, even if there were no apparent problems with the exterior, the interior was often not in a balanced state.

[0008] Furthermore, due to the properties of concrete, aging utility poles absorb a lot of moisture. Depending on the environment, in addition to moisture, salt and other substances can cause oxidation of the concrete and the reinforcing steel inside. This means that they are constantly at risk of damage from external environmental factors, impacts, or loads from additional cables.

[0009] Therefore, in order to solve the above-mentioned problems, the present invention proposes a method for reinforcing utility poles equipped with scaffolding bolt holes by supplying an injectable material to the inside of the utility pole, which minimizes vibration and shock received by the utility pole and helps improve the work speed and safety of the worker supplying the injectable material, by expanding the diameter of the threaded portion formed for fastening scaffolding bolts with a special drill bit, but only expanding the diameter of the plastic portion corresponding to the scaffolding bolt hole.

[Modes for carrying out the invention]

[0015] The following are examples of the principles of the present invention. Those skilled in the art will be able to embody the principles of the present invention and realize various devices that fall within the concept and scope of the present invention, even if they are not explicitly described or illustrated herein.

[0016] Furthermore, it should be understood that all conditional terms and examples provided herein are, in principle, intended to aid in understanding the concepts of the present invention, and the present invention is not limited to such examples and forms.

[0017] A method for reinforcing a utility pole 20 equipped with scaffolding bolt holes 10 according to one embodiment of the present invention involves supplying an injectable material to the inside of the utility pole. Grout material manufacturing step S100 involves mixing and stirring the raw materials stored in the water storage tank and the powder storage tank using a mixer to produce grout material, A utility pole reinforcement means preparation step S200 involves attaching a drill bit 110 to an impact drill 100 and connecting an injection device 210 to a hose connector 200 connected to the mixer, The drill bit 110 is inserted into a scaffolding bolt hole formed in the utility pole, and a primary nail is driven into the rear end of the plastic scaffolding bolt hole that is closed, leaving the nailed space and the drill bit intact, in order to minimize the impact on the utility pole that occurs during nailing, in a primary nailing step S300, The tip of the drill bit is inserted into the scaffolding bolt hole, and secondary nailing is performed in the plastic scaffolding bolt hole, a secondary nailing step S400 to prevent the problem of uneven distribution when inserting wire steel wire, The waterproofing liquid stored in the waterproofing liquid storage tank is supplied through the scaffolding bolt holes where the secondary nailing has been performed, and then cured to form a waterproofing layer 300 on the inner surface of the utility pole in a waterproofing layer forming step S500, A wire insertion step S600 is used to insert numerous wire steel wires 400 into the inside of the utility pole through the scaffolding bolt holes where the secondary nailing described above has been performed, An injection device 210 is connected to a hose connector 200 connected to the above mixer, and after supplying grout material through the scaffolding bolt holes of the utility pole, the pole is cured to form a reinforcing layer 500 inside the utility pole in the utility pole internal reinforcement step S700, It is characterized by including.

[0018] In this case, the grout material contains 100 parts by weight of grout material and 0.03 to 0.08 parts by weight of polypropylene fiber reinforcement per 100 parts by weight of grout material, characterized in that the particle size of the aggregate is 2 mm or less.

[0019] At this time, the drill bit 110 minimizes the impact on the utility pole while enlarging the diameter of the scaffolding bolt hole. Furthermore, the grout material contains a polypropylene fiber reinforcement agent, and by injecting it into the inside of the utility pole, an increase in strength due to the grout material is obtained, and clogging during grout injection can be prevented.

[0020] In this case, the drill bit 110 has a two-stage configuration and is characterized by comprising a first nailing portion 111 having a certain diameter and a second nailing portion 112 connected to the first nailing portion and formed to be larger in diameter than the first nailing portion. For example, if the outer diameter of the scaffolding bolt hole is 22 mm, the first nailing portion has a diameter of less than 20 mm and the second nailing portion has a diameter of 20 mm to 21 mm.

[0021] In this case, the hose connector 200 connected to the mixer is characterized by comprising a mixer coupling portion 205 that connects to the end of the mixer, and an injection device coupling portion 207 that inserts and fixes a coupling projection formed on one side of the injection device to one side of the mixer coupling portion.

[0022] In this case, the injection device 210 is characterized by comprising a coupling projection 215 formed on one side so as to be coupled to the injection device coupling portion 207, and a grout material injection portion 220 connected to the coupling projection for injecting grout material supplied from the mixer into the scaffolding bolt holes.

[0023] In this case, the waterproofing liquid is provided as a liquid epoxy to strengthen the adsorption force between the aging utility pole and the injected material, and is applied by coating.

[0024] The following describes in detail, with reference to examples, a method for reinforcing utility poles equipped with scaffolding bolt holes according to the present invention, which involves supplying an injectable material to the interior of the utility pole.

[0025] Figure 3 is a process diagram showing a method for reinforcing a utility pole equipped with scaffolding bolt holes, according to one embodiment of the present invention, which involves supplying an injectable material to the inside of the utility pole.

[0026] As shown in Figure 3, the utility pole reinforcement method according to the present invention, which involves supplying an injectable material to the interior of a utility pole 20 equipped with scaffolding bolt holes 10, Grout material manufacturing step S100 involves mixing and stirring the raw materials stored in the water storage tank and the powder storage tank using a mixer to produce grout material, A utility pole reinforcement means preparation step S200 involves attaching a drill bit 110 to an impact drill 100 and connecting an injection device 210 to a hose connector 200 connected to the mixer, The drill bit 110 is inserted into a scaffolding bolt hole formed in the utility pole, and a primary nail is driven into the rear end of the plastic scaffolding bolt hole that is closed, leaving the nailed space and the drill bit intact, in order to minimize the impact on the utility pole that occurs during nailing, in a primary nailing step S300, The tip of the drill bit is inserted into the scaffolding bolt hole, and secondary nailing is performed in the plastic scaffolding bolt hole, a secondary nailing step S400 to prevent the problem of uneven distribution when inserting wire steel wire, The waterproofing liquid stored in the waterproofing liquid storage tank is supplied through the scaffolding bolt holes where the secondary nailing has been performed, and then hardened to form a waterproofing layer 300 on the inner surface of the utility pole in a waterproofing layer forming step S500. A wire insertion step S600 is used to insert numerous wire steel wires 400 into the inside of the utility pole through the scaffolding bolt holes where the secondary nailing described above has been performed, An injection device 210 is connected to a hose connector 200 connected to the above mixer, and after supplying grout material through the scaffolding bolt holes of the utility pole, the pole is cured to form a reinforcing layer 500 inside the utility pole in the utility pole internal reinforcement step S700, It is characterized by including.

[0027] The following explanation will be detailed with reference to the attached diagrams.

[0028] 1. Grout material manufacturing step S100 Grout material manufacturing step S100 is the process of manufacturing grout material by mixing and stirring the raw materials stored in the water storage tank and the powder storage tank using a mixer.

[0029] The above-mentioned powder storage tank may consist of multiple tanks, each of which may store cement, sand, gravel, admixtures, etc.

[0030] The raw materials stored in the powder storage tank may be supplied to the mixer by manual means, such as using a shovel, or by piping made of flexible material with clamps on the pipeline that allow for assembly and disassembly.

[0031] For supply via piping, transfer means (not shown), such as pumps or screw conveyors, may be provided to transport the raw materials along the piping.

[0032] The mixer is configured to mix and stir the raw materials stored in the water storage tank and the powder storage tank.

[0033] Such a mixer has a stirring shaft and stirring blades inside, with a motor attached to the stirring shaft, and the mixing and stirring of the raw materials is performed by the motor.

[0034] Furthermore, as mentioned above, the mixer may be connected to a water storage tank and a powder storage tank by piping, and configured to supply the appropriate amount of raw materials directly.

[0035] Preferably, the grout material comprises 100 parts by weight of grout material and 0.03 to 0.08 parts by weight of polypropylene fiber reinforcement per 100 parts by weight of grout material, characterized in that the aggregate particle size is 2 mm or less.

[0036] Regarding the composition of the above-mentioned grout material, commercially available reinforcing grout materials that are known may be used, but since scaffolding bolt holes are utilized, it is preferable to use crushed grout material with aggregate particle size of 2 mm or less.

[0037] Furthermore, in order to minimize the evaporation of moisture from the grout material and to enhance the adhesion between the deteriorated cement and the injected cement, polypropylene fiber reinforcement may be mixed in at a rate of 0.03 to 0.08 parts by weight per 100 parts by weight of grout material to improve the elastic modulus and flexural strength of the injected grout material.

[0038] 2. Preparation step S200 for utility pole reinforcement means The above-mentioned utility pole reinforcement preparation step S200 is the process of attaching the drill bit 110 to the impact drill 100 and connecting the injection device 210 to the hose connector 200 connected to the mixer.

[0039] Specifically, as shown in Figure 6, the drill bit 110 is characterized by being composed of two stages, including a first nailing portion 111 having a fixed diameter, and a second nailing portion 112 connected to the first nailing portion and formed to be larger in diameter than the first nailing portion.

[0040] Preferably, when the outer diameter of the scaffolding bolt hole is 22 mm, the first nailing portion has a diameter of less than 20 mm, and the second nailing portion has a diameter of 20 mm to 21 mm.

[0041] For example, in conventional methods of reinforcing aging utility poles using scaffolding bolt holes, only the inner plug portion of the 16mm inner diameter scaffolding bolt hole 50 is nailed in before insertion. However, clogging occurs, causing the mild steel wire to bend and resulting in an uneven distribution, as confirmed by endoscopic imaging during the insertion process and by cutting the utility pole. To address this, the present invention uses a special drill bit to first nail the closed portion of the rear surface of the 22mm outer diameter scaffolding bolt hole, minimizing the impact on the utility pole by expanding only the plastic portion of the scaffolding bolt hole to 20mm. This provides the advantage of allowing the mild steel wire to be inserted into the interior while maintaining the same shape as before insertion.

[0042] As shown in Figure 7, the hose connector 200 connected to the mixer is characterized by comprising a mixer coupling portion 205 that connects to the end of the mixer, and an injection device coupling portion 207 that inserts and fixes a coupling projection formed on one side of the injection device into one side of the mixer coupling portion.

[0043] Specifically, a mixer coupling portion 205 is provided and connected to the end of the mixer, and an injection device coupling portion 207 is formed on one side of the mixer coupling portion, into which a coupling projection formed on one side of the injection device is inserted and fixed.

[0044] In this configuration, the injection device 210 includes a coupling projection 215 formed on one side so as to be coupled to the injection device coupling portion 207, and a grout material injection portion 220 connected to the coupling projection for injecting grout material supplied from the mixer into the scaffolding bolt holes.

[0045] In other words, a connecting projection 215 is provided and connected to the injection device connecting part 207, and as shown in Figure 8, the grout material injection part 220 is connected to the connecting projection, so that the grout material supplied from the mixer is injected into the scaffolding bolt holes.

[0046] 3.1 First nailing step S300 The above-described primary nailing step S300 involves inserting the drill bit 110 into the scaffolding bolt hole formed in the utility pole, performing primary nailing on the rear end of the plastic scaffolding bolt hole closure, leaving the nailed space and drill bit intact, and minimizing the impact on the utility pole that occurs during nailing.

[0047] As shown in Figure 5, the drill bit 110 is inserted into the scaffolding bolt hole 50 formed in the utility pole, and the primary nail is driven into the rear end of the plastic scaffolding bolt hole that is being closed.

[0048] In this case, as shown in the figure, the space where the nail was driven and the drill bit remain intact, and the impact on the utility pole generated during nailing can be minimized.

[0049] 4.2 Secondary nailing step S400 The above secondary nailing step S400 is a process in which the tip of the drill bit is inserted into the scaffolding bolt hole to perform secondary nailing of the plastic scaffolding bolt hole, thereby preventing the problem of uneven distribution when inserting the wire steel wire.

[0050] As shown in Figure 5, by inserting the tip of the drill bit into the scaffolding bolt hole and performing secondary nailing of the plastic scaffolding bolt hole, the problem of uneven distribution during the insertion of wire steel can be prevented.

[0051] 5. Waterproof layer formation step S500 The above waterproof layer formation step S500 is a process in which waterproof liquid stored in a waterproof liquid storage tank is supplied through the scaffolding bolt holes where the secondary nailing has been performed, and then hardened to form a waterproof layer 300 on the inner surface of the utility pole.

[0052] In this case, the waterproofing liquid is provided as a liquid epoxy to strengthen the adsorption force between the aging utility pole and the injected material, and is applied using this liquid epoxy.

[0053] Furthermore, when applying the waterproofing layer 300, if necessary (depending on the viscosity of the waterproofing liquid, the degree of hardening of the waterproofing liquid, and the degree of excessive application of the waterproofing liquid), the scaffolding bolts at the bottom of the utility pole may be removed so that any remaining waterproofing liquid, other than that adhering to the inner wall surface of the utility pole, can be discharged to the outside through the scaffolding bolt holes.

[0054] Figure 9 shows the state in which a waterproof layer 300 has been formed on the inner surface of the utility pole before the insertion of the wire steel wire 400.

[0055] 6. Steel wire insertion step S600 The above-described steel wire insertion step S600 is the process of inserting a large number of wire steel wires 400 into the inside of the utility pole through the scaffolding bolt holes where the secondary nailing has been performed.

[0056] In this case, the wire steel 400 may be inserted through a scaffolding bolt hole filled with grout material, or it may be inserted through an upper scaffolding bolt hole.

[0057] Inserting wire steel 400 further improves the shear reinforcement capacity, but an insertion nozzle may be used when inserting the wire steel.

[0058] In other words, once the supply of waterproofing fluid through a commonly used insertion nozzle is complete, the nozzle clamp is loosened to separate the supply hose from the insertion nozzle. Then, the wire is pushed through the large opening of the insertion nozzle, and the wire is inserted into the inside of the utility pole through the funnel-shaped insertion nozzle, making it easy to insert the wire 400.

[0059] 7. Utility pole internal reinforcement step S700 The above-described utility pole internal reinforcement step S700 is a process in which an injection device 210 is connected to a hose connector 200 connected to a mixer, grout material is supplied through the scaffolding bolt holes of the utility pole, and then cured to form a reinforcement layer 500 inside the utility pole.

[0060] For example, as shown in Figure 8, the grout material is supplied by connecting the injection device 210 to the hose connector 200 connected to the mixer and then inserting it into the scaffolding bolt hole of the utility pole.

[0061] Next, after a curing process, a reinforcing layer like the one shown in Figure 9 is formed inside the utility pole.

[0062] In short, the present invention minimizes impact on the utility pole while enlarging the diameter of the scaffolding bolt holes using the drill bit 110, and the grout material contains a polypropylene fiber reinforcement agent. It has been confirmed that by introducing this into the inside of the utility pole, a grout material with higher performance in various strength measurements compared to existing grout materials can be obtained.

[0063] Furthermore, by following the process described above, it becomes possible to perform reinforcement work on approximately 30 aging utility poles using just one 1-ton truck.

[0064] According to the present invention, the threaded portion formed for fastening scaffolding bolts is enlarged using a special drill bit, but by enlarging only the plastic portion corresponding to the scaffolding bolt hole, the vibration and impact received by the utility pole are minimized, which helps to improve the work speed and safety of the worker supplying the injectable material.

[0065] Those skilled in the art in the field to which the present invention belongs will understand that the invention can be implemented with various modifications without departing from the technical idea and features of the present invention. Therefore, the embodiments described above should be understood as merely illustrative and not limiting.

[0066] The scope of the present invention is defined more by the appended claims than by the above detailed description, and all modifications or altered forms derived from the meaning and scope of the claims, and their equivalent concepts, should be interpreted as falling within the scope of the present invention.
