Description

Technical Field

[0001] The invention relates to the field of transmission iron tower reinforcement, and in particular to a transmission iron tower reinforcement foundation based on settlement monitoring and a transmission iron tower. Background Art

[0002] Transmission line towers are infrastructure used for the allocation and transmission of electric power resources. In some special areas, the lines inevitably need to pass through coal goafs, which have an important impact on the stability of the foundation of the transmission line towers, and have a great negative impact on the early design and later operation and maintenance of power facilities. The foundation of the transmission line tower in the coal goaf area generally uses a reinforced concrete straight plate foundation with a correction function. Due to the long operation cycle of the transmission line, its special terrain conditions often lead to uneven settlement and inclination of the tower foundation in the goaf area, causing the foundation to pull the transmission line tower, causing the transmission line to tilt or the rods to produce tensile and compressive deformation, which requires timely repair in the later stage to ensure the overall stability of the tower and maintain its normal use function.

[0003] The uneven settlement of the tower foundation in the goaf area and the deformation of the tower's own rods have an important impact on the normal use of the transmission line. The actual uneven settlement size of the tower foundation is often small and difficult to observe with the naked eye. During its operation, the transmission tower is monitored in real time using an inclinometer and a static level, and fixed-point and directional reinforcement is carried out based on the monitoring data, which can effectively improve the efficiency of the later operation and maintenance of the transmission tower. Therefore, it is particularly important to propose a comprehensive technology for real-time monitoring and reinforcement that can provide directional and fixed-point reinforcement measures. Summary of the invention

[0004] In view of the uneven settlement of the tower foundation in the existing goaf area and the low settlement value, real-time monitoring means are adopted. According to the foundation settlement value of the lower part of each tower leg and the tower inclination data, a transmission tower reinforcement foundation and transmission tower based on settlement monitoring are proposed. The reinforcement and reinforcement device has deformation and force amplification effects, and the deformation and force amplification coefficient of the reinforcement and reinforcement device can be set according to the settlement and inclination data obtained by real-time monitoring, so as to solve the stability problems of the transmission tower caused by foundation settlement and tower inclination in different directions in a targeted manner, without the need for later manpower adjustment, and effectively improve the stability of the transmission tower.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] In the first aspect, the present invention discloses a transmission tower reinforcement and enhancement foundation based on settlement monitoring, including a reinforcement and enhancement device, a spiral anchor, and a plate foundation; the reinforcement and enhancement device includes a first-level load-bearing device, a second-level load-bearing device, a first-level force transmission chain rod, a second-level force transmission chain rod, a first-level force chain rod, a second-level force transmission chain rod, a first-level load-bearing device, a second-level load-bearing device, an anti-buckling steel pipe and an energy-absorbing steel rod; the first-level load-bearing device is connected to the second-level load-bearing device through a first-level force transmission chain rod, a first-level force chain rod, and a second-level force transmission chain rod that are hinged in sequence, the first-level force chain rod is connected to the first-level load-bearing device and the second-level load-bearing device through a second-level force transmission chain rod, the anti-buckling steel pipe is sleeved on the energy-absorbing steel rod, and the two ends of the energy-absorbing steel rod are respectively connected to the first-level load-bearing device and the second-level load-bearing device; the first-level load-bearing device is connected to the plate foundation, and the second-level load-bearing device is connected to the spiral anchor.

[0007] The reinforcement device has deformation and force amplification effects, and can set the deformation and force amplification coefficient of the reinforcement device according to the settlement and inclination data obtained through real-time monitoring, thereby specifically solving the stability problems of the transmission tower caused by foundation settlement and tower inclination in different directions. No subsequent manpower adjustments are required, and the stability of the transmission tower is effectively improved.

[0008] As a further technical solution, the first-level loading device and the second-level loading device each include a loading ear plate and a loading ear plate of an integral structure; wherein the loading ear plate includes one, the loading ear plate includes four, and the four loading ear plates are 90 degrees to each other.

[0009] As a further technical solution, the first and second secondary load-bearing devices and the second secondary load-bearing devices each include an integrated fixing screw hole and a secondary load-bearing ear plate, with four secondary load-bearing ear plates distributed in four directions along the front, back, left and right of the fixing screw hole.

[0010] As a further technical solution, the first-level force-bearing chain rod includes a first-level main chain rod, and a first-level force-bearing ear plate and a first-level force-transmitting ear plate are respectively arranged at both ends of the first-level main chain rod, and the axis of the connecting hole of the first-level force-bearing ear plate and the axis of the connecting hole of the first-level force-transmitting ear plate are at 90°.

[0011] As a further technical solution, the first-level force-bearing ear plate is used to connect the first-level force transmission chain rod and the second-level force transmission chain rod; the first-level force transmission ear plate is used to connect the second-level force transmission chain rod.

[0012] As a further technical solution, the energy-absorbing steel rod includes an energy-absorbing section, an anti-buckling section, and a fixed constraint section. The fixed constraint section is located at both ends of the energy-absorbing steel rod, and the anti-buckling section is located in the middle of the energy-absorbing steel rod, dividing the energy-absorbing steel rod into multiple energy-absorbing sections.

[0013] As a further technical solution, the inner diameter of the anti-buckling steel pipe is the same as the outer diameter of the anti-buckling section of the energy-absorbing steel rod. The anti-buckling steel pipe is sleeved on the anti-buckling section of the energy-absorbing steel rod, and its two ends are connected to the inner end of the fixed constraint section.

[0014] As a further technical solution, the plate foundation comprises four plate foundations, which are arranged in four directions: front, back, left and right, and two reinforcement devices are connected to the side of each plate foundation.

[0015] As a further technical solution, two reinforcement devices connected to each slab foundation are arranged adjacent to each other and are located on the surface of the slab foundation away from the center of the transmission tower.

[0016] As a further technical solution, the anti-buckling steel tube and the energy-absorbing steel rod can be replaced by a viscoelastic energy-absorbing system, a friction energy-absorbing device or a spring-type reset device.

[0017] In a second aspect, the present invention further provides a transmission tower, which is installed on the above-mentioned transmission tower reinforcement and enhancement foundation based on settlement monitoring.

[0018] The beneficial effects of the present invention are as follows:

[0019] The reinforcement and enhancement device of the present invention adopts a bridge mechanism with a double displacement amplification function to amplify the settlement or lateral displacement of the iron tower column twice, thereby increasing the deformation of the energy-consuming steel rod and improving the shock absorption control effect. When the iron tower column sinks or tilts and moves sideways, the first and second load-bearing devices are driven to generate axial deformation through the connecting ear plate, and the first and second load-bearing devices drive the first and second force transmission chain rods to move horizontally, thereby driving the first force transmission chain rod to generate lateral displacement, thereby promoting the movement of the second force transmission chain rod, and the second force transmission chain rod drives the first and second load-bearing devices to generate axial displacement, and the second load-bearing devices drive the energy-absorbing steel rods to yield and deform and consume energy, thereby achieving its shock-absorbing reinforcement control effect; the reinforcement and enhancement device of the present invention adopts the displacement amplification mechanism twice, which can amplify the non-uniform settlement and lateral displacement of the iron tower column in the goaf of the transmission line, thereby enhancing the shock-absorbing reinforcement effect of the reinforcement and enhancement device on the iron tower column, and makes up for the defect that the weak nonlinearity or linear elastic state under the small deformation condition of the traditional damper cannot be reinforced; the two-stage deformation amplification factors are both adjustable, and the reverse difference in the amplification factors of the two-stage amplification mechanism under the action of tension and compression loads can ensure that the reinforcement and enhancement effect of the reinforcement and enhancement device under the action of tension and compression loads remains consistent.

[0020] 2. The present invention can effectively improve the deformation stability of the energy-consuming steel bars in the reinforcement device by arranging four sets of additional displacement amplification devices symmetrically at the bottom of the transmission tower, thereby avoiding excessive local deformation differences; the deformation and force amplification coefficient of the reinforcement device can be adjusted based on real-time monitoring data to improve the overall stability of the transmission tower, and the inclination angle ∠ α and ∠β The magnification can be changed by adjusting the effective length of the energy-absorbing section of the energy-absorbing steel rod, that is, adjusting the length of the threaded fixing area at the end of the energy-absorbing steel rod.

[0050] Further, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the reinforcement device 1 in this embodiment includes a primary load-bearing device 101, a primary force transmission chain rod 102, a primary force-bearing chain rod 103, a secondary force transmission chain rod 104, a secondary load-bearing device 105, an anti-buckling steel pipe 106 and an energy-absorbing steel rod 107;

[0051] The first-level load-bearing device 101 includes two, namely the first-level load-bearing device 101 and the second-level load-bearing device 101; the second-level load-bearing device 105 also includes two, namely the first-level load-bearing device 105 and the second-level load-bearing device 105; the first-level load-bearing device 101 is connected to the second-level load-bearing device 101 through the first-level force transmission chain rod 102, the first-level force chain rod 103, and the second-level force transmission chain rod 102 which are hinged in sequence (the connection method is hinged), the first-level force chain rod 103 is hinged to the first-level load-bearing device 105 and the second-level load-bearing device 105 through the second-level force transmission chain rod 104, and an energy-absorbing steel rod 107 is mounted on the anti-buckling steel pipe 106, and the two ends of the anti-buckling steel pipe 106 are respectively connected to the first-level load-bearing device 105 and the second-level load-bearing device 105.

[0052] like Fig. 9 As shown, each first-level load-bearing device 101 includes a loading ear plate 10101 and a loading ear plate 10102 of an integrated structure; wherein the loading ear plate 10101 includes one, and the loading ear plate 10102 includes four, and the four loading ear plates 10102 are mutually 90 degrees, that is, distributed along the four directions of front, back, left, and right, each loading ear plate 10102 of the first-level load-bearing device 101 is connected to the first-level force transmission chain rod 102, and there are four first-level force transmission chain rods 102 in total, each first-level force transmission chain rod 102 is connected to one end of a first-level force-bearing chain rod 103, and the other end of the first-level force-bearing chain rod 103 is hinged to the second-level force transmission chain rod 102, and the four second-level force transmission chain rods 102 are hinged to the same second-level load-bearing device 101, forming an octagonal structure;

[0053] like Fig.10 As shown, connecting holes are provided at both ends of the primary force transmission chain rod 102 .

[0054] like Fig.11 As shown, the above-mentioned primary force-bearing chain rod 103 includes a primary main chain rod 10301, a primary force-bearing ear plate 10302 and a primary force-transmitting ear plate 10303; the primary force-bearing ear plate 10302 includes two, which are respectively located at the two ends of the primary main chain rod 10301; the primary force-transmitting ear plate 10303 also includes two, which are respectively located near the ends of the primary main chain rod 10301, and the connecting hole axes of the primary force-bearing ear plate 10302 and the primary force-transmitting ear plate 10303 are 90 degrees. The primary force-bearing ear plate 10302 is used to connect the primary force-transmitting chain rod 102; the primary force-transmitting ear plate 10303 is used to connect the secondary force-transmitting chain rod 104;

[0055] like Fig.12As shown, the secondary load-bearing device 105 includes a fixing screw hole 10501 and a secondary force-bearing ear plate 10502 of an integrated structure, and there are four secondary force-bearing ear plates 10502, which are distributed in four directions of the front, back, left, and right of the fixing screw hole 10501; the fixing screw hole 10501 is threadedly connected to the fixed constraint section 10703 of the energy-absorbing steel rod 107; the four secondary force-bearing ear plates 10502 are respectively connected to four secondary force-transmitting chain rods 104;

[0056] like Fig.15 As shown, the energy dissipation steel rod 107 in this embodiment includes an energy dissipation section 10701, an anti-buckling section 10702, and a fixed constraint section 10703. The fixed constraint section 10703 is located at both ends of the energy dissipation steel rod 107, and the anti-buckling section 10702 is located in the middle of the energy dissipation steel rod 107, dividing the energy dissipation steel rod 107 into multiple energy dissipation sections 10701; in this embodiment, the anti-buckling section 10702 includes two sections, and the energy dissipation section 10701 includes three sections. The two anti-buckling sections 10702 divide the energy dissipation steel rod 107 into three energy dissipation sections 10701;

[0057] Further, such as Fig.14 , Fig.16 As shown, the inner diameter of the anti-buckling steel tube 106 is the same as the outer diameter of the anti-buckling section 10702 of the energy-absorbing steel rod 107. The anti-buckling steel tube 106 is sleeved on the anti-buckling section 10702 of the energy-absorbing steel rod 107, and both ends are connected to the inner end of the fixed constraint section 10703. The anti-buckling steel tube 106 prevents the energy-absorbing steel rod 107 from buckling, thereby achieving balanced tensile and compressive deformation.

[0058] Furthermore, the fixed constraint section 10703 of the energy dissipation steel bar 107 is processed with threads, which are screwed into the fixed screw hole 10501 of the secondary load-bearing device 105. The inner diameter of the anti-buckling steel pipe 106 is the same as the outer diameter of the anti-buckling section 10702 of the energy dissipation steel bar 107, which prevents the energy dissipation steel bar 107 from buckling and achieves balanced tensile and compressive deformation. This part belongs to the energy dissipation reinforcement system, which can also be changed to a viscoelastic energy dissipation system, a friction energy dissipation reinforcement system, and can also be changed to a reset system with a self-recovery function such as a spring, a disc spring, and a ring spring, thereby achieving column reset.

[0059] Connection method: The transmission tower 5 is fixed to the top of the plate foundation 3 by bolts, and the ear plate 4 (such as Fig.18 As shown in the figure, the spiral anchor 2 can be inserted into the iron tower column by extending and embedding; the spiral anchor 2 is inserted into the soil outside the foundation, and the ear plate 4 connected thereto can be bolted or welded to the spiral anchor fixing plate 202 of the spiral anchor 2; both ends of the energy-absorbing steel rod 107 are fixed to the fixing screw holes 10501 of the secondary load-bearing device 105 by threads to achieve synchronous deformation; the reinforcement device 1, the spiral anchor 2 and the plate foundation 3 are all hinged by ear plates and cylindrical hinges.

[0060] Further, such as Fig.19 As shown, the spiral anchor 2 includes an anchor rod 201 and a spiral anchor fixing plate 202 ; the spiral anchor fixing plate 202 is connected to the reinforcement device 1 .

[0061] Further, such as Fig.17 As shown, the plate foundation 3 includes an iron tower column 301, a primary foundation plate 302 and a secondary foundation plate 303; the primary foundation plate 302 is fixed on the secondary foundation plate 303, and the iron tower column 301 is fixed on the secondary foundation plate 303; the iron tower column 301 is used to fix the iron tower.

[0062] Furthermore, the energy dissipation device provided inside the above-mentioned reinforcement and enhancement device can be replaced, and can be adjusted to a viscoelastic energy dissipation system, friction and other energy dissipation devices, or can be adjusted to a reset device such as a ring spring, disc spring or spring.

[0063] The working mechanism is as follows:

[0064] The reinforcement device 1 uses a bridge mechanism with a double displacement amplification function to amplify the settlement or lateral displacement of the iron tower column 301 twice, and the multiples of the two amplifications depend on Figure 5 Middle ∠ α ,∠ β The size of α represents The angle between the axis of the primary force transmission chain rod 102 and the horizontal line; ∠ β represents The angle between the axis of the secondary force transmission chain rod 104 and the vertical line; wherein the horizontal line described here is parallel to the axis of the anti-buckling steel pipe 106; wherein the vertical line described here is perpendicular to the axis of the anti-buckling steel pipe 106; when ∠ α and ∠ β When the angle is less than 45°, the reinforcement device 1 can amplify the displacement of the iron tower column 301 twice. α and ∠ β The smaller the magnification, the higher the final magnification is the product of the two displacement magnifications, thereby increasing the deformation of the energy-absorbing steel rod 107 and improving the shock absorption control effect. The four sets of additional displacement amplification devices arranged symmetrically in the annular direction can effectively improve the stability of the deformation of the energy-absorbing steel rod 107 in the reinforcement and enhancement device 1. When the iron tower column 301 sinks or tilts sideways, the first-level load-bearing device 101 is driven to produce axial deformation through the connecting ear plate 4, and the first-level load-bearing device 101 drives the first-level force transmission chain rod 102 to move horizontally, and then drives the first-level force transmission chain rod 103 to produce lateral displacement, and then promotes the movement of the second-level force transmission chain rod 104, and the second-level force transmission chain rod 104 drives the second-level load-bearing device 105 to produce axial displacement, and the second-level load-bearing device 105 drives the energy-absorbing steel rod 107 to yield and consume energy, so as to achieve its shock absorption reinforcement control effect.

[0065] Note: The reinforcement device 1 is under tension. αdecreases, the primary deformation and force amplification effect increase, and under compressive conditions ∠ α As the magnification angle increases, the primary deformation and force amplification effect decrease; while the secondary deformation and force amplification effect are the opposite, that is, the secondary deformation and force amplification effect decrease under tension and increase under compression. It can be seen that by reasonably designing the magnification angle, the reverse amplification effect of the two can make up for the reverse difference of the deformation and force amplification effect under tension and compression loads.

[0066] The present invention can adjust the deformation and force amplification coefficient of the reinforcement device based on the real-time monitoring data of the transmission tower to improve the overall stability of the transmission tower. α and ∠ β The magnification can be changed by adjusting the effective length of the energy-absorbing section of the energy-absorbing steel rod, that is, adjusting the length of the threaded fixing area at the end of the energy-absorbing steel rod.

[0067] Specifically, the settlement monitoring of transmission towers may include the monitoring of transmission tower settlement and the measurement of transmission tower inclination angles. There are two main monitoring systems for transmission tower settlement. The first is settlement measurement based on inclination sensors. However, this method can only reflect the settlement state of transmission towers and cannot quantify the settlement value. The second is transmission tower settlement monitoring based on Beidou differential positioning technology. Therefore, three Beidou settlement monitoring devices can be selected, two of which are placed at monitoring points (front tower crane monitoring point 1 51 and rear tower crane monitoring point 2 52), and one is placed at the tower crane reference point 53. The monitoring points are set on a set of diagonal tower bases of the transmission tower, and the reference points are set at fixed positions in the measurement area, such as Fig. 20 The specific measurement scheme is as follows:

[0068] (1) Instrument selection Beidou subsidence monitoring equipment uses FH-900Y equipment. Other equipment includes bracket, Beidou antenna, Beidou base station, data acquisition instrument, computer and screwdriver, etc.

[0069] (2) Equipment calibration

[0070] Ensure the correct installation and calibration of monitoring equipment and Beidou antenna to ensure data accuracy.

[0071] (3) Base station selection

[0072] Choose a stable location to set up the base station, or use an existing base station and ensure its location is known and stable.

[0073] (4) On-site investigation

[0074] Make sure there are no obstructions in the measurement area to avoid factors that interfere with the Beidou signal.

[0075] (5) Installation and measurement

[0076] The monitoring equipment and Beidou antenna are installed on the diagonal tower base and base station of the transmission tower, and the monitoring equipment is started to collect data. In order to achieve high-precision data, static observation is used for collection, and monitoring is performed every few hours or one day.

[0077] (6) Data processing

[0078] Use Beidou differential technology (such as RTK or PPP) to process the data to eliminate atmospheric errors and other interference. Apply real-time or post-processing differential correction to improve data accuracy. Compare the data of the tower base and the base station to calculate the vertical position change, that is, the settlement of the transmission tower.

[0079] (7) Error correction

[0080] Regularly check monitoring equipment and data acquisition systems to ensure there are no faults or errors. Compare measurement results with expectations and make necessary corrections.

[0081] (8) Report writing

[0082] Summarize settlement data and draw settlement change diagrams. Evaluate the impact of transmission tower settlement on transmission tower structure. Provide data support for the comprehensive early warning monitoring system for transmission tower settlement in goaf areas.

[0083] Transmission tower tilt angle measurement scheme: The transmission tower tilt angle definition formula is: ,in is the horizontal inclination value of the transmission tower measurement point, is the actual ground height of the transmission tower measurement point. Fig.21 As shown, is the center point of the top of the transmission tower, is the center point of the tower base. for At the projection point at the tower base, the tilt value for Dot and The distance of the point, the actual ground height for and The distance between the points can be used to calculate the inclination , and then calculate the tilt angle .

[0084] At present, there are five main measurement methods: plumb bob method, theodolite method, plane mirror method, ground three-dimensional laser method and inclination sensor method. Among them, the theodolite method is the most commonly used measurement method, but the on-site operation is complicated. After considering the three factors of personnel operation range, operation difficulty and instrument measurement accuracy, this measurement plan uses the inclination sensor method. The inclination sensor can be attached to the surface of the structure to directly collect the angle between the structure and the geodetic reference plane. .

[0085] Four tilt sensors are selected. The first tilt sensor 54 is installed at the base of the transmission tower to monitor the tilt angle of the tower base. The second tilt sensor 55 and the third tilt sensor 56 are installed at the second and third crossbars of the transmission tower respectively, and are used to measure the tilt angle of the transmission tower for engineering. The fourth tilt sensor 57 is installed at the top crossbar of the transmission tower, and is used to measure the tilt angle of the transmission tower for scientific research. If the on-site operation is difficult, the fourth tilt sensor 57 can be selected. Sensor installation position Fig. 22 shown.

[0086] Considering the difficulty of on-site operation, it is necessary to further explain the installation positions of the second inclination sensor 55 and the third inclination sensor 56. If it is a high tower, the second inclination sensor 55 and the third inclination sensor 56 are installed at the second and third cross bars of the tower. If it is a small tower, the second inclination sensor 55 and the third inclination sensor 56 are installed at the third and fourth cross bars of the tower.

[0087] The specific measurement scheme is as follows:

[0088] (1) Instrument selection

[0089] The inclination sensor used is T220-10 sensor, which is a dual-axis inclination sensor with high precision and wide operating temperature range; other equipment includes sensor fixing bracket, data acquisition system, laptop computer, lifting frame and screwdriver, etc.

[0090] (2) Preliminary preparation

[0091] Before the sensor manufacturer delivers the equipment, calibrate the T220-10 inclination sensor to ensure its measurement accuracy. Check the data acquisition system to ensure that the data is recorded accurately.

[0092] (3) On-site investigation

[0093] Conduct site surveys to confirm available installation locations on top of transmission towers. Ensure safety of installation area and assess working environment and risks.

[0094] (4) Transportation and installation

[0095] Use a lift or other safety equipment to transport the sensor and the bracket to the top of the tower. Select a suitable location on the top of the tower to install the bracket and ensure its stability. Fix the inclination sensor to the bracket and ensure that its horizontal plane is parallel to the top of the tower.

[0096] (5) Connection calibration

[0097] Connect the sensor to the data acquisition system with a cable to ensure stable signal transmission. After installation, perform an on-site calibration to confirm that the sensor reads accurately.

[0098] (6) Data collection

[0099] Start the data acquisition system and ensure that the sensor data is recorded normally. Record the initial data as a baseline.

[0100] (7) Long-term monitoring

[0101] Set the frequency of data collection as needed (e.g. once an hour). Ensure stable storage of data for subsequent analysis.

[0102] (8) Data analysis

[0103] Download data and import the data from the acquisition system into the computer. Analyze the tilt angle and use data analysis software to process and analyze the tilt data and generate a trend chart of the tilt angle.

[0104] (9) Error correction

[0105] Check sensors and data acquisition systems regularly to ensure there are no faults or errors. Compare measurements with expectations and make necessary corrections.

[0106] (10) Report writing

[0107] Write reports including measurement data, tilt analysis, charts and trend forecasts. Evaluate the impact of the tilt of transmission towers on structural safety. Provide data support for the comprehensive early warning monitoring system for transmission tower settlement in goaf areas.

[0108] By acquiring the historical data of these monitoring devices, the lengths of each primary force transmission chain rod, primary force bearing chain rod, secondary force transmission chain rod, anti-buckling steel pipe and energy dissipation steel rod of the reinforcement and enhancement device of the present invention are designed.

[0109] The present invention adopts the displacement amplification mechanism twice, which can amplify the non-uniform settlement and lateral displacement of the iron tower column in the goaf area of ​​the transmission line, thereby enhancing the shock-absorbing and reinforcing effect of the reinforcement device on the iron tower column, making up for the defect that the traditional damper cannot be reinforced in the weak nonlinear or linear elastic state under small deformation conditions; the circumferentially arranged displacement amplification structure can effectively improve the force and deformation stability of the reinforcement and reinforcement device, and avoid excessive local deformation differences; the two-stage deformation amplification factors are both adjustable, and the reverse difference in the amplification factors of the two-stage amplification mechanism under the action of tension and compression loads can ensure that the reinforcement and reinforcement effect of the reinforcement and reinforcement device under the action of tension and compression loads remains consistent.

[0110] Furthermore, this embodiment also provides a transmission tower, the bottom of which is fixed on the transmission tower reinforcement device. Since the transmission tower is provided with the transmission tower reinforcement device, the transmission tower also has all the advantages as described above.

[0111] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0112] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
