Description

Technical Field

[0001] This utility model belongs to the field of foundation adjustment technology, specifically relating to an adjustment beam for power tower foundations. Background Technology

[0002] With the robust development of the industrial economy and the increase in electricity consumption, power transmission lines have become the most basic infrastructure. The terrain along the lines is highly variable, especially since some lines cannot avoid coal mining subsidence areas. Despite various methods being used to address these issues, the surface structure is still damaged to varying degrees. The natural soil has a low specific gravity and a high porosity, resulting in loose foundation soil and reduced bearing capacity. This ultimately leads to increased settlement of the power tower foundation, causing varying degrees of surface subsidence and cracking. Consequently, the power towers tilt, experience longitudinal and lateral displacement, and exhibit conductor and ground wire pull-out phenomena, creating unsafe factors for the operation and maintenance of power transmission lines.

[0003] Goaf areas are divided into old goaf areas, current goaf areas, and future goaf areas. After the underground coal seam is mined, the overlying rock strata lose their support, the equilibrium condition is disrupted, resulting in collapse, caving, and bending deformation. This eventually leads to ground subsidence and surface collapse, forming surface-moving basins. Surface deformation in goaf areas can be categorized into two types of movement and three types of deformation. The two types of movement are subsidence and horizontal movement, and the three types of deformation are tilting, curvature, and horizontal deformation. Coal mining causes ground subsidence, depressions, and even collapses, posing a significant threat and hazard to high-voltage power transmission lines passing through or located in mining areas. Since power towers are a crucial component of power transmission lines, their safe operation is essential for ensuring uninterrupted power supply to users. To prevent the collapse and tilting of power towers in goaf areas, ensure the safe operation of power transmission lines in goaf areas, guarantee regional economic development and electricity supply for industrial, agricultural, and residential use, and ensure the safe power supply of transmission lines in the region, it is necessary to reinforce and protect the foundations of power towers in goaf areas and address potential line hazards.

[0004] However, existing technologies rely on external reinforcement. But to connect the external facilities to the power tower foundation, the power tower foundation needs to be excavated to expose the internal steel bars. Then, additional steel bars are welded to the steel bars inside the power tower foundation before connecting to the external facilities. However, this method involves excavating the power tower foundation to a greater depth, which can damage the integrity of the power tower foundation itself and reduce its strength. Summary of the Invention

[0005] Based on this, this application provides an adjusting beam for power tower foundations to solve the technical problem that the existing method of excavating the power tower foundation to expose the internal steel bars and welding other steel bars to the internal steel bars of the power tower foundation before connecting it to external facilities will damage the integrity of the power tower foundation itself and reduce its strength.

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0007] An adjusting beam for power tower foundations, used for vertical adjustment of power tower foundations, comprising:

[0008] A clamp assembly, comprising two connecting clamps that interlock and wrap around the side of the power tower foundation;

[0009] Adjusting beam, the adjusting beam being connected to the outside of the connecting hoop;

[0010] A foundation beam is provided around the foundation of the power tower and located below the adjusting beam;

[0011] Adjustment assembly, used to adjust the distance between the adjustment beam and the pier beam;

[0012] The adjustment component is vertically mounted on the pier beam, and the adjustment beam is connected to the adjustment component.

[0013] Preferably, the two connecting hoops are detachably connected to each other and clamped to the side of the foundation.

[0014] Preferably, the connecting hoop has several grouting holes.

[0015] Preferably, it further includes a reinforcing part disposed in the adjusting beam and connected to the clamp assembly to improve the connection strength between the adjusting beam and the clamp assembly.

[0016] Preferably, the reinforcing part includes a quick-connect part and an anchoring steel bar. The quick-connect part is located on the outside of the connecting hoop, and one end of the anchoring steel bar is connected to the quick-connect part, while the other end is located in the adjusting beam.

[0017] Preferably, the quick-installation part includes a sleeve, which is connected to the outside of the connecting hoop, and one end of the anchoring steel bar is connected to the sleeve.

[0018] Preferably, the adjusting assembly includes a lead screw that extends vertically through the adjusting beam, a nut is connected to the lead screw and is located below the adjusting beam, and the lower end of the lead screw is fixed to the support beam.

[0019] Preferably, a protective sleeve is provided at the upper end of the lead screw.

[0020] Compared with the prior art, this application has at least the following advantages:

[0021] This application provides an adjusting beam for power tower foundations, which "straightens" the power tower foundation and effectively solves the problem of power tower foundation tilting caused by surrounding soil settlement or collapse, thereby avoiding safety hazards caused by the tilting of the power tower. Furthermore, it connects the power tower foundation by directly wrapping it around the outer surface of the foundation with two connecting hoops. Compared to the traditional method (which requires chiseling open the power tower foundation to expose the reinforcing steel bars before connecting them to the adjusting beam), this method avoids the reduction in the strength of the power tower foundation due to chiseling, and also avoids the occurrence of internal cracks in the power tower foundation due to the impact of the tools used during chiseling. This avoids safety hazards during construction and prevents damage to the original strength of the power tower foundation. Attached Figure Description

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please refer to Figures 1 to 8 In one specific embodiment of this application,

[0034] An adjusting beam for power tower foundations, used for vertical adjustment of power tower foundations, comprising:

[0035] A clamp assembly, comprising two connecting clamps 101, which interlock and wrap around the side of the power tower foundation.

[0036] Adjusting beam 401, which is connected to the outside of connecting hoop 101;

[0037] A foundation beam 501 is provided around the foundation of the power tower and is located below the adjusting beam 401;

[0038] An adjustment assembly is used to adjust the distance between the adjustment beam 401 and the pier beam 501.

[0039] The adjustment component is vertically mounted on the pier beam 501, and the adjustment beam 401 is connected to the adjustment component;

[0040] In actual operation, firstly, a foundation beam 501 is set up around the foundation (the concrete foundation connecting the power tower legs). (Taking concrete as an example, a platform is created around the foundation using concrete and allowed to dry completely.) Then, two connecting hoops 101 are connected to the side of the foundation, connecting them to each other. Next, a suitable number of adjusting components are erected on the foundation beam 501, ensuring they are vertical. Then, adjusting beam 401 is placed on the foundation beam 501 and connected to the adjusting components. Here, we take a concrete adjusting beam 401 as an example. After the adjusting components are erected on the foundation beam 501, a space for concrete pouring is constructed using molds, and the two connecting hoops... Both 101 and the adjustment component are located in the mold. Then, concrete is poured into the mold, and when the concrete solidifies, it connects with the two connecting hoops 101 and the adjustment component to form the adjustment beam 401. Then, the adjustment beam 401 is adjusted by using the adjustment component to change the distance between the adjustment beam 401 and the foundation beam 501, causing the foundation to shift. For example, if the foundation is tilted to the left due to collapse or settlement, the adjustment beam 401 is lifted on the left side by jacks, so that the left side of the adjustment beam 401 is raised. At this time, the adjustment beam 401 is in the form of a "lever" in the left and right directions. Using the lever principle, the foundation is shifted to the right to restore the foundation to a vertical state. Finally, the height of the adjustment beam 401 is fixed by using the adjustment component.

[0041] The above method allows for the "straightening" of the power tower foundation without damaging its original foundation. This effectively solves the problem of the power tower tilting caused by the surrounding soil subsidence or collapse, thus preventing safety hazards caused by the tilting of the power tower. Furthermore, the connection is achieved by directly wrapping the outer surface of the power tower foundation with two connecting hoops 101. Compared to the traditional method (which requires chiseling open the power tower foundation to expose the steel reinforcement and then connecting it to the adjusting beam 401), this method avoids the reduction in the strength of the power tower foundation due to chiseling and also avoids the occurrence of internal cracks in the power tower foundation due to the impact of the tools used during chiseling. This avoids safety hazards during construction and prevents damage to the original strength of the power tower foundation.

[0042] In addition, in order to make the operation faster and more convenient during construction, the two connecting hoops 101 described in this application are detachably connected to each other and clamped to the side of the foundation.

[0043] During operation, the two connecting hoops 101 are attached to both sides of the power tower foundation, so that the two connecting hoops 101 are attached to the sides respectively, and then the two connecting hoops 101 are connected together with bolts, thereby achieving connection by using the two connecting hoops 101 to fit on the side of the power tower foundation.

[0044] In this way, a quick connection to the power tower foundation can be achieved without having to chisel open the power tower foundation to expose the internal steel bars, thus avoiding any impact on the strength of the power tower foundation and preventing any damage to the power tower foundation.

[0045] In addition, the two connecting hoops 101 are clamped to the power tower foundation by bolts, which can achieve a strong connection. In the height direction, in order to improve the position fixation effect of the two connecting hoops 101;

[0046] Therefore, the connecting hoop 101 is provided with a plurality of grouting holes 102;

[0047] The grout is injected into the gap between the connecting hoop 101 and the power tower foundation through the grouting hole 102, so that the grout fills the gap. After the grout dries and solidifies, it can achieve a tight contact and fit between the connecting hoop 101 and the power tower foundation, thereby making the connection between the connecting hoop 101 and the power tower foundation more thorough and tight.

[0048] In the traditional method, in order to ensure quality and strength, the steel bars exposed after the power tower foundation is chiseled together are connected to the external facilities. In this application, it is also necessary to improve the connection strength between the clamp assembly and the adjusting beam 401.

[0049] Therefore, this application also includes a reinforcing part, which is disposed in the adjusting beam 401 and connected to the clamp assembly to improve the connection strength between the adjusting beam 401 and the clamp assembly;

[0050] The reinforcement can be made of steel bars or other steel structures, or other devices that can connect the clamp assembly and the adjusting beam 401;

[0051] During use, after the reinforcing part is connected to the clamp assembly and fixed, the adjusting beam 401 can be connected to the reinforcing part to complete the connection between it and the clamp assembly. Taking the concrete mentioned above as an example, after the reinforcing part (such as steel bar) is fixed to the clamp assembly (connecting hoop 101), a mold can be built around it, and then concrete is poured into the mold. After drying and molding, the adjusting beam 401 can be stably connected to the clamp assembly.

[0052] Specifically, an embodiment of the reinforcement section in the above process is provided:

[0053] The reinforcing part includes a quick-connect part and an anchoring steel bar 202. The quick-connect part is located on the outside of the connecting hoop 101. One end of the anchoring steel bar 202 is connected to the quick-connect part, and the other end is connected to the adjusting beam 401. The quick-connect part can be a positioning sleeve or a device that can quickly position the anchoring steel bar 202 on the outside of the connecting hoop 101.

[0054] During construction, a sufficient number of quick-connect parts are fixed to the outside of the connecting hoop 101, and then the anchoring steel bars 202 are inserted into the corresponding quick-connect parts and fixed together. The fixing method can be to use connectors for connection or direct welding. Then the anchoring steel bars 202 are directly poured into the adjusting beam 401 to complete the construction. Through the above method, the anchoring steel bars 202 can be quickly positioned and fixed, and the anchoring steel bars 202 can be directly connected to the outside of the connecting hoop 101. This eliminates the need to chisel open the original power tower foundation and connect it to the internal steel bars. The connection with the adjusting beam 401 is achieved without damaging the original power tower foundation and the connection strength is guaranteed.

[0055] Specifically, an example is provided for the quick-release section in the above process:

[0056] The quick-installation part includes a sleeve 201, which is connected to the outside of the connecting hoop 101, and one end of the anchoring steel bar 202 is connected to the sleeve 201;

[0057] During construction, a sufficient number of sleeves 201 are fixed to the outside of the connecting hoop 101, and then the anchoring steel bars 202 are respectively inserted into the corresponding sleeves 201 and fixed together. The fixing method can be threaded (both the inner wall of the sleeve 201 and the end of the anchoring steel bar 202 are threaded, so the anchoring steel bar 202 can be screwed into the sleeve 201) for connection or welding. Then the anchoring steel bars 202 are directly poured into the adjusting beam 401 to realize the rapid installation and disassembly of the anchoring steel bars 202.

[0058] Specifically, an embodiment of the adjustment component in the above process is provided:

[0059] The adjustment assembly includes a lead screw 303, which vertically passes through the adjustment beam 401. A nut 304 is connected to the lead screw 303 and is located below the adjustment beam 401. The lower end of the lead screw 303 is fixed to the support beam 501.

[0060] When pouring concrete into the foundation beam 501, the lower end of the screw rod 303 is poured into the foundation beam 501 and kept vertical. After the foundation beam 501 dries and sets, the nut 304 is screwed into the screw rod 303, and then the adjusting beam 401 can be erected on the nut 304. At this time, the screw rod 303 passes through the adjusting beam 401, and the adjusting beam 401 can move along the axial direction of the screw rod 303. During adjustment, a jack can be placed on the foundation beam 501 below the adjusting beam 401, and then the adjusting beam 401 is lifted upwards for adjustment. After the adjusting beam 401 drives the clamp assembly to restore the power tower foundation to a vertical state, the nut 304 is turned to move upwards on the screw rod 303 until it contacts the bottom of the adjusting beam 401. Then the jack is removed, and the limiting position of the nut 304 prevents the adjusting beam 401 from falling, thus completing the adjustment.

[0061] By means of the above method, the height of the adjusting beam 401 can be effectively fixed after the adjusting beam 401 is adjusted, thereby keeping the state of the adjusting beam 401 stable.

[0062] In addition, the lead screw 303 is exposed to the outside world and is easily washed and corroded by rainwater, which will cause the lead screw 303 to rust and reduce its strength. Therefore, a protective sleeve is provided on the upper end of the lead screw 303. After the adjustment beam 401 is adjusted, the protective sleeve can be put on the lead screw 303 for protection. The protective sleeve can be waterproof cloth or waterproof roll material, etc.

[0063] Further, see Figures 7 to 8 The diagram shows another shape of the adjusting beam in this application, which is suitable for adjustment on the foundation of a power tower with four legs. Figure 1 The diagram shows a single-leg type power tower foundation. The construction process for both types is the same, only the shape is different. Furthermore, the structure in this application can be adjusted according to the number of legs of the power tower on site, which can meet the requirements for use and effectively adjust and protect the power tower.

[0064] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
