Description

Technical Field

[0001] This utility model belongs to the field of surface structure protection technology in mining subsidence areas, specifically relating to a deformation-resistant reinforcement structure for high-voltage power line tower foundations in mining subsidence areas. Background Technology

[0002] A goaf is a void left after the ore body has been extracted during the mining process. This void typically poses a serious threat to the safe operation of rock structures, groundwater, and surface high-voltage power line towers, which can lead to varying degrees of ground subsidence or other disasters.

[0003] Existing technologies such as grouting reinforcement, foundation modification, and dynamic tilt adjustment suffer from high costs, complex construction, and poor adaptability. For example, grouting reinforcement requires repeated construction, combined with foundation modification, excessive rigidity can easily lead to stress concentration, and dynamic tilt adjustment is a complex process with short timeliness. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant reinforcement structure for high-voltage power line tower foundations in mining subsidence areas, which can achieve a reasonable structure, simple construction, and dynamic adjustment for deformation-resistant reinforcement of high-voltage power line tower foundations.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A deformation-resistant reinforcement structure for high-voltage power line tower foundations in mining subsidence areas includes a high-voltage power line tower base, with a support platform connected to the top of the base; a group of reinforcing piles surrounding the base; the reinforcing piles and the base connected by a concrete connecting beam; an adjustable support device on the top of the concrete connecting beam; and a monitoring system for monitoring the deformation of the high-voltage power line tower base on the support platform.

[0007] Preferably, the reinforcing pile group consists of bored cast-in-place piles or steel pipe piles, arranged in a ring or rectangle around the base of the high-voltage tower.

[0008] Preferably, the adjustable support device is a hydraulic jack, which is used to dynamically adjust the high-voltage tower base.

[0009] Preferably, the monitoring system includes a tilt sensor and a displacement sensor. The tilt sensor is installed on the support platform, and the displacement sensor is installed on the front and rear sides of the bottom of the support platform. Both the tilt sensor and the displacement sensor are electrically connected to a remote data module.

[0010] Preferably, the top of the receiving platform has mounting slots on both sides, the tilt sensor is installed inside the mounting slot, and the top of the mounting slot is provided with a protective cover.

[0011] Preferably, the concrete connecting beam is arranged in a U-shape or a square shape, and the bottom of the concrete connecting beam is connected to a support column.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, a group of reinforcing piles is arranged around the high-voltage tower base and connected to the high-voltage tower base by concrete connecting beams. This connects the originally independent high-voltage tower base and the scattered reinforcing piles into a rigid whole, forming an integrated force-bearing system. The high-voltage tower base is monitored in real time by a monitoring system, which provides data support to a remote data backend. When the high-voltage tower base deforms, hydraulic jacks can be used to adjust the support platform and the high-voltage tower base upwards. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-3As shown, a deformation-resistant reinforcement structure for a high-voltage power line tower base in a mining subsidence area includes a high-voltage power line tower base 1, with a support platform 101 connected to the top of the high-voltage power line tower base 1; a group of reinforcing piles 2 are arranged around the high-voltage power line tower base 1; the reinforcing piles 2 are connected to the high-voltage power line tower base 1 by a concrete connecting beam 3; an adjustable support device is provided on the top of the concrete connecting beam 3; a monitoring system for monitoring the deformation of the high-voltage power line tower base 1 is provided on the support platform 101. Through the structure of the reinforcing piles 2, the pressure caused by settlement can be effectively dispersed and resisted, preventing the high-voltage power line tower base 1 from tilting or deforming. The structure is formed by connecting the high-voltage tower base 1 with the reinforcing pile group 2 via a concrete connecting beam 3, which increases the bearing capacity and deformation resistance of the high-voltage tower base 1. Especially on soft foundations such as mining subsidence areas, it can effectively prevent damage to the high-voltage tower base 1 caused by uneven settlement. The receiving platform 101 is equipped with a monitoring system that can be used to monitor the deformation of the high-voltage tower base 1 in real time. When the high-voltage tower base 1 deforms, the adjustable support device can be adjusted according to the dynamic changes in foundation settlement, which improves the adaptability and flexibility of the system and extends the service life of the structure.

[0021] like Figure 1 and Figure 2 As shown, the reinforcement pile group 2 consists of bored cast-in-place piles or steel pipe piles, arranged in a ring or rectangle around the high-voltage tower base 1. The reinforcement pile group 2 provides additional support through the bored cast-in-place piles or steel pipe piles, distributing the load of the high-voltage tower base 1 evenly to deeper soil layers, thereby enhancing the stability of the overall structure and helping the high-voltage tower base 1 to better resist foundation settlement or deformation in mining subsidence areas or soft foundations.

[0022] like Figure 1 and Figure 2 As shown, the adjustable support device is a hydraulic jack 4. The hydraulic jack 4 is used to dynamically adjust the high-voltage tower base 1. The dynamic adjustment function of the hydraulic jack 4 can help the high-voltage tower base 1 adapt to settlement changes and adjust the support force according to the settlement rate, ensuring that the high-voltage tower base 1 always remains horizontal and avoiding damage or tilting of the high-voltage tower base 1 due to excessive local settlement.

[0023] like Figures 1-3As shown, the monitoring system includes a tilt sensor 5 and a displacement sensor 6. Both tilt sensor 5 and displacement sensor 6 are electrically connected to a remote data module. The tilt sensor 5 is used to monitor the tilt angle of the high-voltage tower base 1 in real time, which can promptly detect whether the high-voltage tower base 1 has tilted or experienced uneven settlement. The displacement sensor 6 can monitor the horizontal or vertical displacement of the high-voltage tower base 1, and track the movement of the high-voltage tower base 1 in real time under the influence of foundation settlement, external loads, or natural disasters. By connecting the tilt sensor 5 and displacement sensor 6 to the remote data module, all monitoring data can be transmitted to the remote monitoring center in real time. Staff can obtain the status information of the high-voltage tower base 1 from a distance, enabling remote monitoring and timely response.

[0024] like Figure 3 As shown, mounting slots 501 are provided on both sides of the top of the receiving platform 101. The tilt sensor 5 is installed inside the mounting slot 501. A protective top cover 502 is provided on the top of the mounting slot 501. The mounting slot 501 provides a stable mounting space for the tilt sensor 5, ensuring that the sensor is firmly fixed on the receiving platform 101 and preventing the sensor position from shifting due to vibration, external force or other factors. The protective top cover 502 protects the tilt sensor 5, preventing damage to the sensor from external environmental factors such as dust, rain, snow, and corrosive gases, thereby extending the service life of the tilt sensor 5 and maintaining its long-term stable working state.

[0025] like Figure 1 and Figure 2 As shown, the concrete tie beam 3 is arranged in a U-shape or a square shape. The bottom of the concrete tie beam 3 is connected to the support column 7. The U-shape or square shape design can form a more stable connection structure between the concrete tie beam 3, the reinforcing pile group 2, and the high-voltage tower base 1. This arrangement can effectively distribute and transfer the load of the superstructure, reduce the stress concentration between the concrete tie beam 3 and the reinforcing pile group 2, and enhance the stability and seismic performance of the overall structure. The support column 7 can support and reinforce the concrete tie beam 3 to prevent the reduction of bending and shear resistance due to the long span of the concrete tie beam 3.

[0026] The working principle of this utility model is as follows: the reinforcing pile group 2 is arranged around the high-voltage tower base 1 and connected to the high-voltage tower base 1 by the concrete connecting beam 3. This can connect the originally independent high-voltage tower base and the scattered reinforcing pile group 2 into a rigid whole, forming an overall force-bearing system. The high-voltage tower base 1 is monitored in real time by the monitoring system and data support is provided to the remote data backend. When the high-voltage tower base 1 deforms, the support platform 101 and the high-voltage tower base 1 can be adjusted upward by the hydraulic jack 4.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
