[0026] The embodiment of the present application provides a frame-type tower suitable for steep areas. By adopting the form of high and low legs, steep mountainous areas can meet the conditions for developing wind power projects, and can also reduce a large amount of earth slope excavation work and reduce machinery costs.

[0027] The following is a detailed description of a frame-type tower suitable for steep areas provided in this embodiment. Figure 1 , Figure 2 As shown, it includes: a tower body 1 and a foundation fixing device 2, the tower body 1 includes four tower columns 11, and the bottom ends of the four tower columns 11 form a high-low leg structure; the foundation fixing device 2 is set to correspond to the tower columns 11, and the bottom ends of the tower columns 11 are connected to the respective corresponding foundation fixing devices 2; wherein, the foundation fixing device 2 includes a foundation column pier 21, a foundation pedestal 22 located at the bottom of the foundation column pier 21, and a foundation pile foundation 23 located at the bottom of the foundation pedestal 22, and the tower columns 11 are connected to the foundation column pier 21.

[0028] In this embodiment, since steep areas have slopes of a certain angle, a high-low leg structure is formed at the bottom of the tower body 1, so that the foundation does not need to be dug into a horizontal state. In this way, the terrain can be effectively utilized to design high and low legs, so as to avoid landslides caused by changes in the topography due to foundation excavation when it rains. At the same time, the high and low legs are supported and connected by a foundation fixing device 2 composed of a foundation pier 21, a foundation pedestal 22 and a foundation pile foundation 23, and have high stability and safety.

[0029] Please refer to Figure 1-Figure 3 As shown, in this embodiment, it should be noted that for steep areas, the slope can be regularized into a lower first-order slope protection 3 and a higher second-order slope protection 4, the first-order slope protection 3 has a first horizontal plane 31, the first horizontal plane 31 connects the first-order slope protection 3 and the second-order slope protection 4, the second-order slope protection 4 has a second horizontal plane 41, and the second horizontal plane 41 is set higher than the first horizontal plane 31.

[0030] In this embodiment, four basic fixing devices 2 are respectively arranged on the first horizontal plane 31 and the second horizontal plane 41, specifically:

[0031] The two foundation fixing devices 2 in the front row are arranged on the first horizontal plane 31 of the lower first-level slope protection 3, and the two foundation fixing devices 2 in the back row are arranged on the second horizontal plane 41 of the higher second-level slope protection 4. Correspondingly, the bottom end length of the two tower columns 11 in the front row is greater than the bottom end length of the two tower columns 11 in the back row, thereby forming a height leg structure. At this time, the bottom ends of the two tower columns 11 in the front row are respectively fixedly connected to the foundation fixing devices 2 located on the first horizontal plane 31, and the bottom ends of the two tower columns 11 in the back row are respectively fixedly connected to the foundation fixing devices 2 located on the second horizontal plane 41. According to Figure 1It can be seen that the front row in this embodiment is the side facing the paper.

[0032] Of course, the two basic fixing devices 2 in the back row can also be arranged on the first horizontal plane 31 of the lower first-level slope protection 3, and the two basic fixing devices 2 in the front row can be arranged on the second horizontal plane 41 of the higher second-level slope protection 4. Correspondingly, the bottom end length of the two tower columns 11 in the back row is greater than the bottom end length of the two tower columns 11 in the front row, so as to form a height leg structure. At this time, the bottom ends of the two tower columns 11 in the back row are respectively fixedly connected to the basic fixing devices 2 in the first horizontal plane 31, and the bottom ends of the two tower columns 11 in the front row are respectively fixedly connected to the basic fixing devices 2 in the second horizontal plane 41.

[0033] In this embodiment, by adopting the first-order slope protection 3 and the second-order slope protection 4, the stability and safety of the slope protection can be improved.

[0034] Please continue to refer to Figure 1-Figure 3 As shown, in this embodiment, it is also necessary to explain that the tower column 11, the foundation pier 21, the foundation pedestal 22 and the foundation pile foundation 23 are arranged on the same axis. It can be understood that by arranging the axes of the tower column 11, the foundation pier 21, the foundation pedestal 22 and the foundation pile foundation 23 on the same straight line, the force directions of these components are consistent and the stability is better.

[0035] In some embodiments, the lower end of the foundation pier 21 extends into the ground, and the upper end of the foundation pier 21 is exposed to the ground. The part of the foundation pier 21 exposed to the ground is the foundation capital, through which the bottom end of the tower column 11 is connected, so that the tower body 1 can be supported by the foundation pier 21.

[0036] In one example, the tower body 1 is vertically arranged, and the tower body 1 is arranged as a structure that is narrow at the top and wide at the bottom, that is, the four tower columns 11 are more gathered closer to the top, and more open closer to the bottom, thereby forming a stable structure that is narrow at the top and wide at the bottom. Since the tower column 11 is equivalent to being arranged at an angle, and the basic column pier 21 and the tower column 11 are arranged coaxially, therefore, in order to match the tower column 11, in this embodiment, the basic column pier 21 is also arranged at an angle with the horizontal plane of the ground, and the value range of the angle is set between 0-90 degrees.

[0037] It should also be noted that the foundation cap 22 is set inside the ground, and the foundation pier 21 and the foundation cap 22 are set at right angles. By setting the foundation cap 22 at right angles to the foundation pier 21, the axis of the foundation cap 22 and the axis of the foundation pier 21 are set on the same straight line, which can keep the force directions of the tower column 11, the foundation pier 21 and the foundation cap 22 consistent. Preferably, the foundation cap 22 is provided with supporting steel bars inside, and the outer wall of the foundation cap 22 is provided with peripheral steel bars. By using the supporting steel bars and peripheral steel bars, the firmness and stability of the foundation cap 22 can be enhanced.

[0038] In this embodiment, it should also be noted that the foundation piles 23 are arranged into several groups, and the several groups of foundation piles 23 are evenly distributed on the foundation platform 22. The foundation piles 23 and the foundation platform 22 are arranged at right angles, and one group of the foundation piles 23 is arranged in the middle position of the foundation platform 22, and is kept in the same straight line with the axis of the foundation platform 22, so that the force direction of the tower column 11, the foundation column pier 21, the foundation platform 22 and the foundation piles 23 is consistent as a whole, thereby improving stability.

[0039] Please refer to Figure 1 As shown, in this embodiment, it should be noted that a plurality of diagonal steel pipes 12 and a plurality of cross steel pipes 13 are arranged between the four tower columns 11; a diagonal steel pipe 12 and a cross steel pipe 13 are arranged between two adjacent tower columns 11, and four diagonal steel pipes 12 are arranged, one end of the four diagonal steel pipes 12 is connected to the middle position of the cross steel pipe 13, and the other end of the four diagonal steel pipes 12 is respectively connected to the corresponding tower column 11. In this way, the connection stability between the tower columns 11 can be guaranteed.

[0040] The implementation principle of this embodiment is as follows: since steep areas have slopes of a certain angle, the slope is regularized into a first-level slope protection 3 and a second-level slope protection 4 to improve the stability of the slope, and then the basic fixing device 2 is respectively arranged on the first horizontal plane 31 of the corresponding first-level slope protection 3 and the second horizontal plane 41 of the second-level slope protection 4, and then the bottom ends of the tower columns 11 are arranged in a high-low leg structure, that is, the bottom ends of the two tower columns 11 in the front row are longer than the bottom ends of the two tower columns 11 in the back row, so that the two tower columns 11 in the front row are The bottom end of 1 is fixed on the foundation fixing device 2 of the first horizontal plane 31, and the bottom ends of the two tower columns 11 in the rear row are fixed on the foundation fixing device 2 of the second horizontal plane 41. In this way, it is not necessary to dig the foundation into a horizontal state. In this way, the high and low legs with alternating heights can be effectively designed by utilizing the terrain, so as to avoid landslides caused by the change of the terrain due to the excavation of the foundation when it rains. At the same time, the high and low legs are supported and connected by the foundation fixing device 2 composed of the foundation column pier 21, the foundation pedestal 22 and the foundation pile foundation 23, and the stability and safety are high.

[0041] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
