Description

Technical Field

[0001] This utility model relates to the technical field of tower correction devices in mining subsidence areas, specifically a tower reinforcement and correction structure for mining subsidence areas. Background Technology

[0002] During mineral resource development, especially coal mining, the area of ​​goaf continues to expand. Affected by factors such as redistribution of stratum stress and roof collapse, goaf areas are prone to ground subsidence and uneven settlement. This geological hazard poses a serious threat to power transmission towers in the area: the tower foundations tilt and shift due to differences in surface settlement, which in turn leads to structural deformation of the tower body and abnormal changes in the stress distribution of the main tower materials and connection nodes.

[0003] Currently, the treatment of power transmission towers in mining subsidence areas mainly adopts methods such as foundation reinforcement or overall relocation, but these methods have significant limitations: traditional foundation reinforcement is difficult to cope with continuous dynamic settlement and cannot achieve real-time correction; overall relocation is costly and can significantly affect the continuous operation of transmission lines. In addition, some correction schemes only focus on single structural reinforcement, neglecting the synergistic adjustment capability between the tower and the foundation, resulting in the inability to maintain the treatment effect in the long term. The risk of tower tilting and deformation still exists, seriously affecting the safe and stable operation of transmission lines. Utility Model Content

[0004] (I) Technical Issues

[0005] This utility model aims to provide a reinforcement and correction structure for transmission towers in mining subsidence areas, so as to effectively reinforce and dynamically correct the deviation of transmission line towers in mining subsidence areas, and ensure the safe and stable operation of the towers.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a reinforcement and correction structure for iron towers in mining subsidence areas, including an anti-sinking beam and an iron tower body. The anti-sinking beam is buried in the foundation, and the iron tower body is installed on the upper end of the anti-sinking beam. The upper end of the anti-sinking beam is integrally cast to form several evenly distributed pressure piers. A locking device is pre-embedded on the upper end of the pressure piers. An adjusting beam is detachably and fixedly connected between the upper ends of the pressure piers through the locking device. The iron tower body is fixedly installed on the upper end of the adjusting beam. A main material reinforcing diagonal brace angle steel is connected between the iron tower body and the adjusting beam. A main material reinforcing angle steel is fixed on the support of the iron tower body. Multiple adjusting platforms for placing jacks are fixed on the upper end of the anti-sinking beam and directly below the adjusting beam.

[0008] Furthermore, the adjusting beam has a grid-shaped structure and is fixedly connected to the tower body to form an integral whole.

[0009] Furthermore, the adjustment platforms are located at the four corners of the adjustment beam and their height is less than that of the pressure piers.

[0010] Furthermore, the locking device includes a threaded rod pre-embedded and fixed at the upper end of the pressure pier, the upper end of the threaded rod passing through the adjusting beam and fixed to the adjusting beam by bolts.

[0011] Furthermore, when the jack lifts the adjusting beam, the gap formed between the pressure pier and the adjusting beam is filled with concrete filler.

[0012] (III) Technical Effects

[0013] The advantages of this utility model compared with the prior art are:

[0014] 1. By combining anti-settlement beams, pressure piers, and grid-shaped adjustment beams, a multi-layered stress system is formed, which effectively disperses the load on the tower body and enhances the overall structure's resistance to uneven ground settlement. The addition of main material reinforcing diagonal bracing angle steel and main material reinforcing angle steel further enhances the structural strength of the tower body and reduces the risk of deformation.

[0015] 2. The adjustment platforms at the four corners of the adjustment beam can be conveniently placed with jacks. The jacks are used to lift the adjustment beam to correct the tower's deviation. The screw and bolt structure of the locking device meets the requirements for dynamic deviation correction. The gap between the pressure pier and the adjustment beam is filled with concrete filler, which can quickly restore the integrity of the structure after deviation correction.

[0016] 3. Compared to the overall relocation solution, this structure significantly reduces engineering costs through local reinforcement and in-situ correction. Simultaneously, its detachable adjustable beam design facilitates later maintenance and secondary adjustments, extending the service life of the tower and reducing redundant construction investment. It can adapt to the geological environment of continuous dynamic settlement in mining subsidence areas and can be flexibly adjusted according to the tower's tilt degree, making it suitable for reinforcement and correction scenarios of transmission line towers of different specifications.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1 A structure for reinforcing and correcting the deviation of a steel tower in a mining subsidence area includes an anti-sinking beam 1 and a steel tower body 2. The anti-sinking beam 1 is buried in the foundation, and the steel tower body 2 is installed on the upper end of the anti-sinking beam 1. The upper end of the anti-sinking beam 1 is integrally cast to form several evenly distributed pressure piers 3. A locking device 4 is pre-embedded on the upper end of the pressure piers 3. An adjusting beam 5 is detachably and fixedly connected between the upper ends of the pressure piers 3 through the locking device 4. The steel tower body 2 is fixedly installed on the upper end of the adjusting beam 5. A main material reinforcing diagonal bracing angle steel 6 is connected between the steel tower body 2 and the adjusting beam 5. A main material reinforcing angle steel 7 is fixedly installed on the support of the steel tower body 2. Multiple adjusting platforms 8 for placing jacks are fixedly installed on the upper end of the anti-sinking beam 1 and directly below the adjusting beam 5.

[0023] The adjusting beam 5 has a grid-like structure and is fixedly connected to the tower body 2 to form an integral unit. The adjusting platforms 8 are distributed at the four corners of the adjusting beam 5 and are less than the height of the pressure pier 3. The locking device 4 includes a threaded rod pre-embedded and fixed to the upper end of the pressure pier 3, the upper end of the threaded rod passing through the adjusting beam 5 and fixed to the adjusting beam 5 by bolts. When the jack lifts the adjusting beam 5, the gap formed between the pressure pier 3 and the adjusting beam 5 is filled with concrete filler 9.

[0024] The working principle of this utility model is as follows: In daily use, the anti-settlement beam 1, buried in the foundation, provides the basic load-bearing capacity for the entire structure. The pressure pier 3 at its upper end is connected and fixed to the grid-shaped adjustment beam 5 through the locking device 4, so that the adjustment beam 5 and the tower body 2 form a stable whole. The main material reinforcing diagonal bracing angle steel 6 and the main material reinforcing angle steel 7 provide structural reinforcement from the connection nodes between the tower body and the adjustment beam and the tower body support, respectively, to improve the overall resistance to deformation. When the subsidence of the goaf causes the tower to tilt, jacks are placed on the adjustment platforms 8 at the upper end of the anti-settlement beam 1 and the four corners of the adjustment beam 5. The bolts on the locking device 4 are loosened, and then the adjustment beam 5 is lifted by the jacks, so that the tower body 2 is raised synchronously with the adjustment beam 5 to correct the tilt angle. At this time, a gap is created between the pressure pier 3 and the adjusting beam 5 due to the lifting. After adjusting to the preset position, concrete filler 9 is filled into the gap. After the concrete solidifies, it forms a rigid support. Then, the bolts on the locking device 4 are tightened to fix the adjusting beam 5. Finally, the structural reinforcement after correction is completed to ensure that the iron tower remains stable in the dynamic settlement environment.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
