Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a narrow gable tower foundation. Background Technology

[0002] In power transmission line engineering, the towers serve as crucial supporting structures, and the stability of their foundations directly impacts the safe operation of the entire transmission line. This is especially true in mountainous areas with complex terrain, where the selection of tower locations and foundation design present numerous challenges. In geography, a ridge is a specific form of mountain ridge, a narrow section connecting two peaks or highlands. A narrow ridge refers to a relatively narrow section of the ridge, typically the top or ridgeline of a mountain, characterized by its narrow width and steep slopes on both sides.

[0003] The selection of a tower site on a narrow ridge requires special consideration of terrain stability and construction feasibility. Due to the narrow width and steep slopes on both sides of the ridge, traditional foundation treatment methods, such as... Figure 1 As shown, in conjunction with the inclined tower foundation (the foundation structure built to support and fix tower-type structures such as the 300-meter tower), a large number of base reductions, slope protection retaining walls 200 meters below the slope (stone retaining walls, concrete retaining walls, geogrid retaining walls, etc.), and tower 300 meters higher are adopted. However, the adverse effects of this are that the amount of earthwork is large, the natural slope of the mountain is severely damaged, and geological landslides are easily induced, which in turn affects the stability of the tower foundation. Utility Model Content

[0004] This utility model provides a narrow mountain ridge tower foundation, which can solve the technical problem of insufficient stability of tower foundations constructed on narrow mountain ridges.

[0005] This application provides the following technical solution:

[0006] A narrow-beam tower foundation includes a tower body and tower legs that are fixedly connected. The tower legs include several vertical leg frames and connecting beams for connecting the leg frames. A base plate is fixedly installed on the top of the connecting beams. A reinforcing plate is fixedly installed on the base plate. The reinforcing plate is fixedly connected to the base plate and the tower body respectively. Stiffening plates are vertically fixed on both sides of the stiffening plates. The stiffening plates are parallel to the reinforcing plates in the length direction.

[0007] Beneficial effects:

[0008] 1. Improve the overturning resistance and lateral stability of the tower foundation: By installing connecting beams between the tower legs, the legs are connected into a complete frame structure, effectively improving the overall stiffness and overturning resistance of the foundation. This design can significantly improve the lateral stability of the foundation, especially in narrow mountain ridge environments with complex terrain, narrow width, and steep slopes. It avoids the problems of large earthwork volume and severe damage to the natural slope of the mountain caused by the construction of large-scale foundation lowering and retaining walls in traditional foundation treatment methods, reduces the risk of geological landslides, and ensures the long-term stability and safety of the tower foundation.

[0009] 2. Forming a stable structural system and enhancing load transfer and overall stiffness: By fixing reinforcing plates and stiffening plates to the base plate, a multi-level stable structural system is formed. The base plate, as a transition component, ensures uniform load transfer from the tower legs to the tower body, avoiding structural damage caused by localized stress concentration. The reinforcing plates significantly enhance the connection strength and overall stiffness between the tower body and tower legs, ensuring the stability of the tower base under external loads. The stiffening plates further enhance the stiffness and stability of the reinforcing plates, preventing deformation or failure during stress, thus providing strong support for the entire tower base and ensuring the safe operation of the transmission line.

[0010] In summary, this narrow mountain ridge tower foundation not only solves many problems existing in traditional tower foundation treatment methods, but also significantly improves the stability of the tower foundation through optimized structural design, providing a reliable guarantee for the safe operation of transmission lines in complex terrain.

[0011] Furthermore, as an improvement, the tower body includes main angle steel and diagonal angle steel, and the reinforcing plate is fixedly connected to the main angle steel and diagonal angle steel respectively.

[0012] Beneficial effects: The main angle steel provides strong vertical support as the primary supporting component, while the diagonal angle steel, in conjunction with the main angle steel, constructs multiple stable triangular structures, further enhancing the tower's bending and shear resistance. This design improves the tower foundation's resistance to overturning and lateral stability on complex terrains such as narrow mountain ridges, ensuring the long-term stability and safety of the tower foundation under various external environmental changes and load impacts.

[0013] Furthermore, as an improvement, the reinforcing plate includes an outer plate located outside the main member angle steel, an inner plate located inside the main member angle steel, and an inclined plate located between the outer plate and the inner plate. The outer plate, the inner plate, and the inclined plate are all welded and fixed to the base plate and the main member angle steel.

[0014] Beneficial effects: The outer and inner side plates wrap around the main angle steel from the outside and inside respectively, while the inclined side plates provide additional support between the two. The welded and fixed connection method further improves the bonding strength between the components, ensuring reliability and durability in long-term use.

[0015] Furthermore, as an improvement, the thickness of both the outer and inner side plates is greater than the thickness of the inclined side plate.

[0016] Beneficial effects: As key components directly in contact with the main angle steel, the outer and inner side plates bear the primary load-bearing responsibility. Thicker outer and inner side plates can better resist stresses caused by external loads and environmental changes, preventing structural deformation or failure during long-term use. In contrast, while the inclined side plates also enhance stability, their main function is to provide auxiliary support; therefore, their thickness can be relatively thinner to optimize material usage and reduce costs.

[0017] Furthermore, as an improvement, the stiffening plate and the reinforcing plate are fixedly connected by welding, and the diagonal angle steel and the inner side plate are fixedly connected by high-strength bolts.

[0018] Beneficial effects: The welded connection between the stiffening plate and the reinforcing plate ensures that they form a unified whole under stress, enhancing the overall rigidity and deformation resistance of the structure. This is particularly effective in preventing structural failure under large external loads or environmental changes. The high-strength bolts used to fix the diagonal angle steel to the inner plate provide greater installation flexibility and maintenance convenience. These high-strength bolts not only guarantee sufficient connection strength but also allow for disassembly and adjustment when necessary, facilitating on-site installation and subsequent maintenance.

[0021] Figure 3 for Figure 2 An enlarged diagram of position A in the middle. Detailed Implementation

[0022] The following detailed description illustrates the specific implementation method:

[0023] The markings in the accompanying drawings include: narrow mountain ridge 100, retaining wall 200, iron tower 300, leg frame 301, connecting beam 302, main material angle steel 303, diagonal material angle steel 304, base plate 400, reinforcing plate 500, outer side plate 501, inner side plate 502, diagonal side plate 503, high-strength bolt 504, and stiffening plate 600.

[0024] Example 1

[0025] like Figure 2 , Figure 3As shown, a narrow mountain ridge 100 tower foundation includes a tower body and tower legs that are fixedly connected. The tower legs include four vertical leg frames 301 and three layers of connecting beams 302 for connecting the four leg frames 301.

[0026] The upper connecting beam 302 is located on the upper part of the leg 301, mainly bearing the load from the upper part of the tower and evenly distributing it to the four legs 301. The middle connecting beam is located in the middle of the leg 301, serving as intermediate support and connection. The middle connecting beam 302 can effectively reduce the slenderness ratio of the leg 301, enhance the overall structural stability, and prevent buckling of the leg 301 under stress. The lower connecting beam 302 is located at the bottom of the leg 301 and directly connects to the ground foundation. The lower connecting beam 302 not only connects the four legs 301 but also forms an integral part with the ground foundation, evenly distributing the load of the tower foundation to the ground and ensuring the stability of the tower foundation.

[0027] A base plate 400 is fixedly installed on top of the upper connecting beam 302. The base plate 400 is made of high-strength steel plate with sufficient load-bearing capacity and corrosion resistance. It serves as a transition component connecting the upper connecting beam 302 and the tower body, distributing the load of the upper connecting beam 302 evenly to the tower body. The tower body includes main angle steel 303 and diagonal angle steel 304. The main angle steel 303 is one of the main supporting components of the power transmission tower, while the diagonal angle steel 304, together with the main angle steel 303, forms a stable triangular structure to enhance the stability of the power transmission tower.

[0028] A reinforcing plate 500 is fixedly installed on the base plate 400. Stiffening plates 600 are vertically fixed on both sides of the reinforcing plate 500, with the stiffening plates 600 parallel to the reinforcing plate 500 along their length. Both the reinforcing plate 500 and the stiffening plates 600 are made of high-strength steel. The reinforcing plate 500 includes an outer plate 501 located outside the main member angle steel 303, an inner plate 502 located inside the main member angle steel 303, and a diagonal plate 503 located between the outer plate 501 and the inner plate 502. The outer plate 501, inner plate 502, and diagonal plate 503 are all welded and fixed to the base plate 400 and the main member angle steel. The thickness of the outer plate 501 and the inner plate 502 is greater than the thickness of the diagonal plate 503. The stiffening plate 600 and the reinforcing plate 500 are fixedly connected by welding. The stiffening plate 600 improves the local strength of the reinforcing plate 500, especially at the connection point. The stiffening plate 600 can effectively disperse stress concentration, reduce stress peaks at the connection point, and improve the reliability of the connection. The diagonal angle steel 304 and the inner side plate 502 are fixedly connected by high-strength bolts 504.

[0029] This embodiment forms a stable structural system by fixing a reinforcing plate 500 and a stiffening plate 600 on the base plate 400. The base plate 400, as a transition component, ensures uniform load distribution; the reinforcing plate 500 significantly enhances the connection strength and overall rigidity between the tower body and tower legs; the stiffening plate 600 further enhances the rigidity and stability of the reinforcing plate 500; and the diagonal angle steel 304 enhances the stability and wind resistance of the tower body. This design has significant practical application value in complex terrain conditions such as narrow mountain ridges 100, effectively ensuring the long-term stable operation of the tower foundation.
