Description

Technical Field

[0001] This utility model belongs to the technical field of wind power transmission line engineering, and in particular, it is a pile stabilization support mechanism for high-altitude wind power transmission line engineering. Background Technology

[0002] With the continuous advancement of my country's renewable energy development strategy, wind power construction is gradually expanding from plains to complex terrain areas such as mountains and hills. When constructing wind power projects in high-altitude areas, traditional engineering pile foundation structures often fail to meet the stability and safety requirements for long-term operation due to factors such as large terrain undulations, complex geological conditions, and frequent wind loads. Therefore, developing a stable support structure for engineering piles that can adapt to complex mountainous environments and possesses good overturning resistance and shock absorption performance has become a key technical problem that urgently needs to be solved in the construction of high-altitude wind power transmission lines.

[0003] Currently, most existing wind power engineering piles adopt single concrete cast-in-place piles or steel support structures, with relatively simple foundation treatment methods, typically fixed simply by direct pouring or driving into the ground. However, in high-altitude environments, this traditional structure has many shortcomings. For example, its design concept is mainly designed for the relatively stable geological conditions and smaller wind loads in plain areas. In high-altitude areas, due to complex terrain, high wind speeds, and frequent gusts, the dynamic external forces borne by the piles increase significantly, and existing structures lack any buffer structure, resulting in an inability to effectively absorb and release external impact energy. When strong winds or earthquakes occur, external forces act directly on the engineering piles and are rapidly transmitted to the foundation structure through rigid connections, causing the piles to resonate or sway violently. Due to the lack of buffer structure design, stress is concentrated at certain critical nodes (such as anchor points or connection parts), which can easily lead to structural fatigue failure, bolt loosening, or even overall overturning. Utility Model Content

[0004] The purpose of this utility model is to provide a stable support mechanism for high-altitude wind power transmission line engineering piles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stabilizing support mechanism for high-altitude wind power transmission line engineering piles, comprising:

[0006] Construction area for wind power transmission lines.

[0007] In this preferred embodiment, a pile foundation pit is excavated in the area, and a sand and gravel support cushion layer, a concrete filling layer and a concrete smoothing support layer are laid sequentially at the bottom of the pile foundation pit. A foundation pit support component is provided on the inner wall of the pile foundation pit, which consists of an outer sand and gravel support edge layer and an inner concrete support edge layer.

[0008] In this preferred embodiment, a U-shaped steel plate is longitudinally embedded at the center of the pile foundation pit and arranged perpendicular to the concrete smoothing support layer. A steel cage is longitudinally installed inside the U-shaped steel plate, and concrete is poured into it to form a concrete support column. A second smoothing layer is installed on top.

[0009] In this preferred embodiment, the engineering piles are installed on the top surface of the second smoothing layer by multiple anchor rods and extend into the concrete support column.

[0010] In this preferred embodiment, a support and buffer assembly is symmetrically installed between the periphery of the U-shaped steel plate and the foundation pit support assembly. This assembly includes an I-shaped steel plate, a hydraulic buffer damper, and a buffer spring, which are used to provide elastic support and dynamic buffering for the U-shaped steel plate.

[0011] In this preferred embodiment, a first smoothing layer is set above the pile foundation pit and between the wind power transmission line construction area and the U-shaped steel plate. Both the sand and gravel support edge layer and the concrete support edge layer are set on the surface of the concrete smoothing support layer. Each hydraulic buffer damper is equipped with a hydraulic station on one side to control its buffering performance.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] The pile stabilization support mechanism for this high-altitude wind power transmission line project, through the design of setting a sand and gravel support pad, a concrete filling layer, and a concrete smoothing support layer at the bottom of the pile foundation pit, enables the foundation to have good drainage performance and bearing capacity, while improving the uniformity and stability of the foundation, realizing the effective support function for the engineering pile body, and achieving the effect of enhancing the overall structure's anti-settlement capacity and construction quality.

[0014] By embedding a U-shaped steel plate longitudinally into the center of the pile foundation pit and perpendicular to the concrete support layer, and setting a steel cage and pouring concrete support columns inside, the structure forms a high-strength, high-rigidity core support system. The steel cage enhances the tensile strength and seismic performance of the concrete columns, realizes the foundation stability function of the engineering pile, and achieves the effect of improving the overall structural bearing capacity and overturning resistance.

[0015] By symmetrically setting support and buffer components between the outer wall of the U-shaped steel plate and the inner wall of the foundation pit support component, the external vibration energy can be effectively absorbed and released. The hydraulic buffer damper and the buffer spring work together to achieve the functions of dynamic shock reduction and elastic support, thus preventing the engineering pile from resonating, displacing or being damaged due to external forces such as wind load and earthquake.

[0016] The entire high-altitude wind power transmission line engineering pile stabilization support mechanism not only has excellent load-bearing performance, but also good buffering and shock absorption capabilities and geological adaptability, realizing the function of safe and stable operation in complex mountainous environments, and achieving the comprehensive technical effect of improving the long-term stability and safety reliability of the wind power transmission line foundation structure.

[0029] The U-shaped steel plate 4 is longitudinally lowered into the middle of the inner cavity of the pile foundation pit 7 and perpendicular to the concrete smoothing support layer 16.

[0031] The support and buffer components are symmetrically arranged between the outer walls of the U-shaped steel plate 4 and the inner walls of the foundation pit support components 10. This allows the support and buffer components to not only support the U-shaped steel plate 4 in the pile foundation pit 7 and prevent it from tilting, but also to buffer the vibrations generated by external forces, preventing the engineering pile 3 from loosening, tilting, or misaligning, thereby improving the installation stability of the high-altitude wind power transmission line.

[0032] In this embodiment, the foundation pit support component 10 includes a ring of sand and gravel support edge layer 8 filled and stacked around the inner wall of the pile foundation pit 7, and a ring of concrete support edge layer 9 poured around the inner wall of the sand and gravel support edge layer 8.

[0036] In this embodiment, a first smoothing layer 2 is provided above the pile foundation pit 7 and between the wind power transmission line construction area 1 and the U-shaped steel plate 4.

[0037] In this embodiment, the engineering pile 3 is located in the middle position above the extension of the U-shaped steel plate 4.

[0038] In this embodiment, both the gravel support edge layer 8 and the concrete support edge layer 9 are constructed on the surface of the concrete smooth support layer 16.

[0039] In this embodiment, a hydraulic station is provided on one side of each hydraulic buffer damper 12 and on the inner wall of the I-shaped steel plate 11.

[0040] Working principle

[0041] The high-altitude wind power transmission line engineering pile stabilization support mechanism selects a suitable route for the construction of the wind power transmission line in the high-altitude area, conducts geological surveys and assessments of geological conditions such as rock type, soil density, and groundwater level, determines the pile layout location, and mechanically excavates a regular pile foundation pit 7 at the selected location according to the design drawings. The size of the pile foundation pit 7 is determined according to the size of the engineering pile and geological conditions, and is usually rectangular. The bottom of the foundation pit is cleared of gravel and debris to ensure foundation stability.

[0042] A layer of sand and gravel support pad 14 is laid at the bottom of the pile foundation pit 7 to serve as drainage, shock absorption and leveling. A concrete filling layer 15 is injected into the gaps of the sand and gravel support pad 14 to enhance the density and bearing capacity. The top layer of concrete is poured and the support layer 16 is smoothed to ensure a flat surface for easy subsequent structural installation.

[0043] A ring of sand and gravel support edge layer 8 is built around the inner wall of the pile foundation pit 7 to prevent the side wall of the foundation pit from collapsing. A ring of concrete support edge layer 9 is poured inside the sand and gravel support cushion layer 14 to further reinforce the slope of the foundation pit. The sand and gravel support cushion layer 14 and the concrete filling layer 15 together form a support structure that combines flexibility and rigidity, which is suitable for unstable geological environments.

[0044] The prefabricated U-shaped steel plate 4 is vertically embedded into the center of the foundation pit, and its bottom surface is tightly attached to the concrete support layer 16. A steel cage 18 is placed longitudinally inside the U-shaped steel plate 4 to enhance the structural strength. A concrete support column 17 is poured to make the U-shaped steel plate 4 tightly bonded to the concrete to form a rigid core. A second smoothing layer 5 is poured on top of the concrete support column 17 to ensure that the connection surface with the upper engineering pile is flat.

[0045] The engineering pile 3 is placed on the second smoothing layer 5, and multiple anchor rods 6 are used to firmly fix the engineering pile 3 in the concrete support column 17. The anchor rods 6 penetrate into the concrete support column 17 to provide a high-strength connection and prevent the engineering pile 3 from slipping or tilting. I-shaped steel plates 11 are symmetrically installed on the outer walls of the U-shaped steel plate 4. Multiple hydraulic buffer dampers 12 are installed between the inner walls of both ends of each I-shaped steel plate 11 and fixed by welding connecting plates. A buffer spring 13 is fitted on each hydraulic buffer damper 12 to achieve elastic support. One end of the buffer component is connected to the U-shaped steel plate, and the other end is connected to the inner wall of the foundation pit support component 10 to form all-round dynamic support. Each hydraulic buffer damper 12 has a hydraulic station on one side, which can adjust the buffer force to adapt to different external environments.

[0046] A first smoothing layer 2 is set above the pile foundation pit, between the wind power transmission line construction area 1 and the U-shaped steel plate 4. The first smoothing layer serves a protective function, while also improving the overall aesthetics and the cleanliness of the construction.

[0047] After installation, under normal conditions: the U-shaped steel plate 14 and the concrete support column 17 jointly bear the weight of the engineering pile 3, and the I-shaped steel plate 14 and the buffer assembly are in a pre-compression state to maintain structural stability.

[0048] When encountering strong winds or vibrations, external forces are transmitted to the engineering pile 3, which in turn acts on the U-shaped steel plate 14. The hydraulic buffer damper 12 in the support buffer assembly begins to compress, absorbing some kinetic energy. The buffer spring 13 further releases elastic energy to offset residual vibrations, keeping the overall structure stable and preventing the engineering pile 3 from tilting or loosening.

[0049] During long-term use: the concrete support column 17 and the steel cage 18 work together to resist the stress caused by soil settlement, the foundation pit support component 10 prevents slope instability and extends service life, and the buffer component can be inspected and replaced regularly as needed to ensure the continuous safety of the structure.
