Its function is to transfer the force of the tower on the foundation to the foundation smoothly and smoothly, so as not to cause instability. Especially for long-distance high-voltage transmission lines, because they pass through a wide area, the terrain and geological conditions are complex and diverse, it is more necessary to reasonably design the type of tower foundation to ensure the normal long-distance high-voltage transmission.

[0003] In the prior art, the power transmission line tower often adopts a cast-in-place pile foundation. This pile foundation is a columnar structure with the upper end fixed to the tower leg of the power transmission line tower and the lower end arranged in the original soil. When in use, the friction resistance between the pile foundation and the original soil is used to bear and transfer the load of the power transmission line tower. When building the pile foundation, it is necessary to drill a columnar hole, place steel bars in the drilled hole and pour concrete to form a pile foundation. However, during construction, drilling takes a certain amount of time, and then the concrete needs to be solidified after pouring. After several days of maintenance, the upper part can be continued to be built after its hardness is enhanced. The construction period is long, and the construction process requires a large number of different types of equipment. In the event of natural disasters such as earthquakes and mudslides, it is difficult to quickly repair the power lines when road transportation is difficult. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 3 As shown, this embodiment includes the following contents: a transmission line iron tower foundation, which includes a metal mounting plate 1, on which a plurality of mounting bolts 14 for connecting with the iron tower are evenly arranged, and array reinforcement members 2 are respectively arranged on the upper and lower sides of the metal mounting plate 1, and a plurality of ground piles 3 are installed on the metal mounting plate 1 through the array reinforcement members 2;

[0026] The array reinforcement members 2 on the upper side of the metal mounting plate 1 and the array reinforcement members 2 on the lower side of the metal mounting plate 1 are symmetrically arranged, each group of reinforcement members 2 includes a reinforcement sleeve 2-1 connected to the metal mounting plate 1, and a plurality of triangular reinforcement rib plates 2-2 are arranged along the circumference at the connection between the reinforcement sleeve 2-1 and the metal mounting plate 1, an annular limiting ring 2-3 is connected to the upper end of the reinforcement sleeve 2-1, a through hole matching the outer diameter of the ground pile 3 is opened in the reinforcement sleeve 2-1, a hole corresponding to the through hole in the reinforcement sleeve 2-1 is opened on the metal mounting plate 1, and the ground pile 3 is movably inserted in the hole of the reinforcement sleeve 2-1 and the metal mounting plate 1;

[0027] An annular limit block 5 is fixed on the ground pile 3, an external thread 4 is opened on the top of the ground pile 3, a nut is movably installed on the external thread 4, and the distance between the external thread 4 and the limit block 5 matches the distance between the two limit rings 2-3 symmetrically installed on the upper and lower sides of the metal mounting plate 1; a pointed head is provided at the bottom end of the ground pile 3.

[0028] By adopting the above technical solution, for the case of hard soil, during installation, the position is first determined according to the holes of the metal mounting plate 1, and then several ground piles 3 are nailed down into the ground in sequence according to the positions, so that the limit block 5 is flush with the ground. Due to the pointed head, the ground pile 3 can be easily nailed down. When the soil is hard or it is installed on a stone ground, the ground pile 3 can also be installed after drilling. Then, the metal mounting plate 1 is lifted and moved above the ground pile 3, so that the ground pile 3 is aligned with the hole of the reinforcement 2, and the metal mounting plate 1 is gradually lowered so that the ground pile 3 is inserted into the reinforcement 2, and then the ground pile 3 is lowered. After the limiting ring 2-3 in the square reinforcement 2 contacts the limiting block 5, the metal mounting plate 1 contacts the ground and transmits pressure, and then a nut is screwed onto the external thread 4 and tightened to fix the ground pile 3 to the metal mounting plate 1. During use, the metal mounting plate 1 and the ground pile 3 are reinforced by the reinforcing sleeve 2-1 to prevent the contact surface between the ground pile 3 and the metal mounting plate 1 from being too small, resulting in a large local pressure and causing the ground pile 3 to bend at the connection with the metal mounting plate 1. At the same time, the reinforcing rib plate 2-2 can increase the connection strength between the reinforcing sleeve 2-1 and the metal mounting plate 1.

[0029] Embodiment 2:

[0030] See also Figure 1-Figure 5 As shown, this embodiment includes the following contents: a transmission line iron tower foundation, which includes a metal mounting plate 1, on which a plurality of mounting bolts 14 for connecting with the iron tower are evenly arranged, and array reinforcement members 2 are respectively arranged on the upper and lower sides of the metal mounting plate 1, and a plurality of ground piles 3 are installed on the metal mounting plate 1 through the array reinforcement members 2;

[0034] The quick locking structure includes a movable groove 8 opened on the side of the connecting column 7, a triangular column-shaped lock tongue 10 is rotatably installed in the movable groove 8 through a rotating shaft 9, a plurality of springs 11 are arranged in the movable groove 8, one end of the spring 11 is connected to the rear position of the lock tongue 10, and the other end of the spring 11 is connected to the inner wall of the movable groove 8, and a card slot 13 matching the shape of the lock tongue 10 is opened in the sliding groove 12;

[0035] A plurality of barb plates 6 are arranged in groups, each group of barb plates 6 includes a plurality of barb plates 6 evenly arranged along the circumference of the ground pile 3 , and the plurality of barb plates 6 are vertically arranged on the ground pile 3 .

[0036] By adopting the above technical scheme, in view of the situation that the soil is relatively soft, on the basis of the first embodiment, the barb plate 6 can be installed on the ground pile 3. During installation, it is only necessary to insert the connecting plug 7 into the sliding groove 12. During the insertion process, the front end of the lock tongue 10 is pressed and retracted into the movable groove 8, and the spring 11 is compressed at the same time. When inserted into place, the lock tongue 10 reaches the card slot 13, and the lock tongue 10 can pop out under the elastic force of the spring 11 and be stuck in the card slot 13 to prevent withdrawal, thereby connecting the barb plate 6 to the ground pile 3.
