[0002] As a key facility supporting power transmission lines, the foundation structure of cement poles is crucial to the safe and stable operation of the power system. With the expansion of power engineering to remote areas and complex terrains, foundation construction technology can no longer meet the diverse engineering needs. The spiral anchoring foundation structure for cement poles, with its high degree of mechanization, convenient installation, and minimal disturbance to the original soil, forms a stable anchor by screwing the spiral anchor into the soil.

[0003] However, in the actual production and installation of existing spiral anchored cement pole foundation structures, there are still shortcomings in the welding of its components. The welding of the anchor rod and anchor leaf, the bearing platform and connecting components of the spiral anchor, etc., used to rely on manual hand-held welding equipment. This method is not only labor-intensive, but also affected by the welder's skill level and fatigue, making it difficult to guarantee the accuracy of the welding position and angle, resulting in inconsistent welding quality and affecting the overall stability and load-bearing capacity of the foundation structure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spiral anchored power cement pole foundation structure, which aims to improve the problem of difficulty in ensuring the accuracy of welding position and angle during the welding of existing spiral anchored power cement pole foundation structures.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3 An embodiment of the present invention provides a spiral anchored power cement pole foundation structure, including a first fixing plate 1, a connecting component 8 fixedly connected to the lower surface of the first fixing plate 1, a first fixing column 3 fixedly connected to the outside of the connecting component 8, an auger 2 fixedly connected to the outside of the first fixing column 3, a first threaded groove 5 provided inside the first fixing plate 1, and a fixing cone 9 fixedly connected to the bottom end of the first fixing column 3.

[0027] Specifically, the top of the first fixing plate 1 has a first threaded groove 5 for threaded connection to the support rod on the foundation. The three first fixing posts 3 on each side reflect the stability of the triangle. The screw auger 2 is a flat iron sheet for the screw ring outside the first fixing post 3, which makes it easier for the first fixing post 3 to penetrate into the ground. The fixing cone 9 reduces the resistance when drilling into the ground. The connecting component 8 makes the connection between the first fixing plate 1 and the first fixing post 3 more precise and prevents deviation.

[0028] Reference Figures 3-4 The connecting component 8 includes a second fixing plate 801, the upper surface of which is fixedly connected to the upper surface of the first fixing plate 1. A first buckle 802 is slidably connected to the outside of the second fixing plate 801, and a second buckle 803 is slidably connected to the outside of the first buckle 802. The upper surface of the second buckle 803 is fixedly connected to the lower surface of the first fixing plate 1, the upper surface of the first buckle 802 is fixedly connected to the lower surface of the first fixing plate 1, and the outside of the second fixing plate 801 is fixedly connected to the outside of the first fixing post 3.

[0029] Specifically, the second fixing plate 801 is a steel plate with right angles on the sides, used to support the first fixing plate 1 and the first fixing post 3 and to weld them. The first buckle 802 and the second buckle 803 are made of plastic. Their purpose is to temporarily clamp the second fixing plate 801 to assist in welding the first fixing plate 1 and the first fixing post 3, thereby achieving a more stable welding process and improving the welding accuracy.

[0030] Reference Figures 5-6 The first fixing plate 1 has a third threaded groove 11 inside its side; a screw 7 is threadedly connected inside its side, and a washer 13 is provided outside the screw 7; a bracket 6 is provided outside the washer 13, and the internal thread of the bracket 6 is connected to the outside of the screw 7; a second threaded groove 10 is provided inside the bracket 6, and the external part of the first fixing plate 1 is provided outside the bracket 6; an inlet hole 4 is opened inside the first fixing post 3, and a storage groove 12 is opened inside the first fixing post 3.

[0031] Specifically, the third threaded groove 11 and the second threaded groove 10 are threaded inside to connect the screw 7, the first fixing plate 1, and the bracket 6, so that the three are connected. The washer 13 is used to make the connection between the screw 7, the first fixing plate 1, and the bracket 6 more stable. The storage tank 12 is used to store cement. The flow holes 4 are set inside the first fixing column 3 and have many to allow cement to flow into the ground and towards the tree roots to grip the ground. This makes the grip of the first fixing column 3 more stable and achieves the effect of strengthening stability.

[0032] Working principle: When the foundation structure is needed, firstly, a crane is connected to the top of the first fixed column 3, then the fixed cone 9 is aligned with the ground and rotated, thereby allowing the fixed cone 9 and the auger 2 to assist the first fixed column 3 in drilling into the ground. When only the top of the first fixed column 3 is exposed on the ground, the connection between the first fixed column 3 and the crane is disconnected. When all three first fixed columns 3 are anchored in the ground, the pre-prepared cement is poured into the storage tank 12 opened inside the first fixed column 3. When the cement is full, it flows into the injection hole 4 opened inside the first fixed column 3, and then into the ground. When the cement solidifies, it can... By tightly connecting with the ground to make the foundation more stable, three second fixing plates 801 are welded to the outside of each first fixing column 3. Then, the first fixing plate 1 is placed on the upper surface of the three first fixing columns 3 and pressed down, so that the first buckle 802 and the second buckle 803 slide outside the second fixing plate 801, thereby clamping the second fixing plate 801. Then, the second fixing plate 801, the first fixing plate 1 and the first fixing column 3 are welded together, so that welding can be done without hand support and the welding effect can be more precise.

[0033] After the four first fixing plates 1 are welded, the bracket 6 is placed on the side of the first fixing plate 1, and the washer 13 is passed through the outside of the screw 7. Then the screw 7 is rotated into the second threaded groove 10 opened inside the bracket 6, so that the screw 7 passes through the second threaded groove 10 and rotates into the third threaded groove 11 opened inside the first fixing plate 1. Thus, the four first fixing plates 1 can be connected and rely on each other, which can achieve the effect of preventing the foundation structure from shifting.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
