[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] This utility model provides a large-plate foundation structure for iron towers, such as... Figure 1 and Figure 2 As shown, it includes a large slab 1, foundation piles 4, and a connecting frame 6, as follows. Figure 4 As shown, multiple upper plates 3 are fixedly connected to the upper surface of the large plate 1. Foundation piles 4 are installed above the upper plates 3, and a connecting frame 6 is installed between the foundation piles 4 and the upper plates 3. Connecting bars 31 are fixedly connected to the upper surface of the upper plates 3. Figure 5 As shown, a connecting bar 5 is fixedly connected to the lower end of the foundation pile 4. A vertical hole 62 is provided through the upper surface of the connecting frame 6. The connecting frame 6 is fitted onto the connecting bar 31 through the vertical hole 62, and the connecting bar 5 is inserted into the vertical hole 62. Figure 6 As shown, a grouting port 61 is provided through the side of the docking frame 6.

[0031] like Figure 6 and Figure 7 As shown, the docking frame 6 is a rectangular frame. Two symmetrically arranged side edges of the docking frame 6 have through-holes 63, and two other symmetrically arranged side edges of the docking frame 6 have through-holes 64. Side holes 63 penetrate the side edges of the docking frame 6 with side holes 64, and side holes 64 penetrate the side edges of the docking frame 6 with side holes 63. Connecting ribs 31 have through-holes 311 on their outer periphery, and connecting ribs 5 have through-holes 51 on their outer periphery. There are two rows of connecting ribs 31, arranged parallel to each other, with multiple ribs 31 in each row, and they are equidistant from each other. Similarly, there are two rows of connecting ribs 5, arranged parallel to each other, with multiple ribs 5 in each row, and they are equidistant from each other. Vertical holes 62 are equidistantly located on the upper surfaces of each side edge of the docking frame 6, as shown in the image. Figure 8 and Figure 9 As shown, connecting rib 31 and connecting rib 5 are respectively inserted into two pairs of mutually perpendicular sidewalls of the mating frame 6. Figure 9 and Figure 10 As shown, a first rod 7 is inserted into the first side hole 63, and the first rod 7 passes through the first insertion hole 311 on the first connecting rib 31 in the same row. A second rod 8 is inserted into the second side hole 64, and the second rod 8 passes through the second insertion hole 51 on the second connecting rib 5 in the same row.

[0032] The docking frame 6 serves as an intermediate connector, enabling rapid assembly of the large plate 1 and the foundation pile 4.

[0033] like Figure 1 and Figure 11As shown, multiple holes 11 are formed through the upper surface of the large plate 1, and anchor rods 2 are inserted into the holes 11. The anchor rods 2 are hollow and have openings at both ends. The lower end of the anchor rod 2 is frustum-shaped. Grouting holes 22 are formed on the outer peripheral side of the anchor rod 2. An interference ring 21 is fixedly connected to the anchor rod 2. A grouting groove 23 is provided on one side of the interference ring 21. The grouting groove 23 is located on the outer peripheral side of the anchor rod 2, near the upper end of the anchor rod 2. Figure 3 and Figure 11 As shown, the outer diameter of the anchor rod 2 is the same as the inner diameter of the plate hole 11. The interference ring 21 is frustum-shaped, and the end face near the lower end of the anchor rod 2 is smaller than the end face of the other end. The anchor rod 2 is inserted into the plate hole 11 and hammered to move it downwards into the soil. The interference ring 21 protrudes from the plate hole 11, and the upper end face of the interference ring 21 contacts the bottom surface of the large plate 1. The interference ring 21 provides support for the large plate 1. When the anchor rod 2 cannot sink downwards, the large plate 1 also cannot sink downwards.

[0034] The hollow interior and open design of anchor rod 2 provide a good channel for grouting operations. Grouting material can be injected from the upper opening of anchor rod 2, conveyed downwards through the hollow cavity, and sprayed out from the lower opening and grouting hole 22, ensuring a smooth grouting process. This allows the anchor rod 2 to be fully filled with grouting material, enhancing the bond between anchor rod 2 and the surrounding soil and rock, and improving the anchoring effect.

[0035] When grouting the anchor rod 2, grouting begins from below the grouting groove 23. After the grouting material fills the area around the grouting hole 22, it accumulates upwards inside the anchor rod 2 until it overflows from the grouting groove 23. The grouting groove 23 is located inside the plate hole 11 of the large plate 1. The overflowing grouting material will fill the gap between the plate hole 11 and the anchor rod 2, strengthening the connection stability between the plate hole 11 and the anchor rod 2.

[0036] The large plate 1 serves as the foundation load-bearing layer and is connected to the anchor rod 2 through the plate hole 11. The large plate 1 is located underground and supports the weight of the entire iron tower, transferring the iron tower load to the foundation.

[0037] Using this utility model, such as Figure 1 and Figure 2As shown, the large slab 1 is placed in the foundation pit, and the anchor rod 2 is vertically inserted into the hole 11 of the large slab 1. Grouting material is injected from the upper opening of the anchor rod 2 and conveyed downward through the hollow cavity until it sprays out from the lower opening and grouting hole 22, so that the anchor rod 2 is fully filled with grouting material, which enhances the bonding force between the anchor rod 2 and the surrounding soil and rock. The connecting frame 6 is inserted into the connecting bar 31 through the vertical hole 62. The connecting bar 5 on the foundation pile 4 is inserted into the vertical hole 62 on the connecting frame 6. The connecting frame 6 needs to be placed horizontally and is located between the large slab 1 and the foundation pile 4. The side holes 63 and 64 are perpendicular to the arrangement direction of the connecting bars 31 and 5. Insert the insert rod 7 into the side hole 63, through the insertion hole 311 of the connecting bar 31 in the same row, and insert the insert rod 8 into the side hole 64, through the insertion hole 311 of the connecting bar 31 in the same row. Hole 2 51, insert rod 1 7 and insert rod 2 8 need to be fully inserted, and then tighten the fixing nuts on insert rod 1 7 and insert rod 2 8. The connecting bar 1 31, the docking frame 6 and the connecting bar 2 5 are fixed together by insert rod 1 7 and insert rod 2 8. Grouting material is injected through the grouting port 61 of the docking frame 6. The grouting material enters the interior of the docking frame 6. After the grouting material solidifies, the large plate 1 and the foundation pile 4 can be fixedly connected together. The construction efficiency is accelerated by the rapid splicing of the prefabricated large plate 1 and the foundation pile 4.

[0038] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
