[0024] An embodiment of the present utility model discloses a precast prestressed pressure-type anti-pulling pile.

[0025] The present utility model provides a precast prestressed pressure-type anti-pulling pile as shown in Figures 1-3 Figure 1. The precast prestressed pressure-type anti-pulling pile includes two anti-pulling pile bodies 1. One end of the two anti-pulling pile bodies 1 close to each other is respectively fixedly connected with a first circular iron block 2 and a second circular iron block 3. A plurality of slots are opened on the side walls of the first circular iron block 2 and the second circular iron block 3. U-shaped inserts 4 are inserted into the corresponding two slots. Two mounting holes are opened on one side of each U-shaped insert 4. Bolts 5 are arranged inside each mounting hole. Each U-shaped insert 4 is fixed respectively by the corresponding two bolts 5. One side of each U-shaped insert 4 is arc-shaped and matches the side walls of the first circular iron block 2 and the second circular iron block 3. A plurality of second internal threaded holes are opened on the side walls of the first circular iron block 2 and the second circular iron block 3. Each second internal threaded hole matches the corresponding bolt 5.

[0026] Weld the two anti-pulling pile bodies 1 around the gap at the joint. Then insert each U-shaped insert 4 into the corresponding slot. Then each bolt 5 can be used to fix the U-shaped insert 4, so as to prevent the solder joint from disconnecting during use.

[0027] In order to improve the anti-pulling property of the anti-pulling pile, as shown in Figure 2 Figure 2, a cylinder 6 is fixedly connected to the lower surface of the first circular iron block 2. A first internal threaded hole is opened on the upper surface of the second circular iron block 3. Threads matching the first internal threaded hole are opened on the surface of the cylinder 6.

[0028] Screw the cylinder 6 into the first internal threaded hole. Then it can be prevented that the connection between the first circular iron block 2 and the second circular iron block 3 can be made closer, thereby improving the anti-pulling property of the anti-pulling pile.

[0029] In order to prevent the first circular iron block 2 and the second circular iron block 3 from separating from the corresponding anti-pulling pile body 1, as shown in Figure 1 、 Figure 2 Figure 3, insertion rods 7 are fixedly connected to one side of the first circular iron block 2 and the second circular iron block 3. A plurality of barbs 8 are fixedly connected to the rod walls of each insertion rod 7. The first circular iron block 2 and the second circular iron block 3 and the corresponding insertion rods 7 and barbs 8 are integrally cast.

[0030] The anti-pulling pile body 1 is made of cement. During the casting process, the first circular iron block 2 and the second circular iron block 2 are placed inside the mold, and then cement slurry is poured in. After the cement slurry solidifies, the cement can wrap the inserting rod 7 and the barbs 8, thereby improving the tensile strength between the first circular iron block 2 and the second circular iron block 3 and the corresponding anti-pulling pile body 1.

[0031] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
