Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 - Figure 2 、 Figure 6, an embodiment provided by the present utility model: a precast concrete pipe pile with stable support, including a first pipe pile 1. An installation plate 3 is fixedly connected to the outer wall of the upper end of the first pipe pile 1. Four support members 2 are arranged on the top of the installation plate 3. A plurality of installation grooves are provided at the left and right ends of the four support members 2 and on the top of the installation plate 3. A plurality of installation members 7 are threadedly connected inside the plurality of installation grooves. A first soft pad 8 is sleeved on the outer periphery of each of the plurality of installation members 7. The first soft pad 8 is located between the installation member 7 and the first soft pad 8. The support member 2 is installed on the top of the installation plate 3 through the installation member 7 and the first soft pad 8. The support member 2 can fix the building materials installed on the first pipe pile 1. Because it is triangular in shape, it can prevent the building materials from shaking and tilting. The bottom of the first pipe pile 1 is connected to a second pipe pile 5 through a connecting member 12. A first protective member 4 is provided on the outer walls of both the second pipe pile 5 and the first pipe pile 1. A plurality of fixing bolts 19 are fixedly connected to the bottom of the second pipe pile 5. A plurality of positioning rods 14 are fixedly connected to the bottom of the first pipe pile 1. A plurality of second connecting grooves are provided at the top of the second pipe pile 5. The positioning rods 14 are slidably connected inside the second connecting grooves. Fixing grooves two are provided on the surfaces of the connecting member 12, the first pipe pile 1, and the second pipe pile 5. A second fixing member 10 is threadedly connected inside the fixing grooves two. Align the fixing groove two on the connecting member 12 with those on the first pipe pile 1 and the second pipe pile 5, and then fix the connecting member 12 to the first pipe pile 1 and the second pipe pile 5 with the second fixing member 10. Align the positioning rods 14 below the first pipe pile 1 with the second connecting grooves on the second pipe pile 5 and insert them, so that the first pipe pile 1 and the second pipe pile 5 are spliced. An excavating member 17 is provided at the bottom of the second pipe pile 5. A plurality of grooves are provided at the top of the excavating member 17. A second soft pad 16 is provided on the outer periphery of each of the plurality of fixing bolts 19. The excavating member 17 and the second soft pad 16 are sequentially sleeved on the fixing bolts 19. A fixing nut 18 is threadedly connected to the outer periphery of the fixing bolt 19. The fixing nut 18 is located directly below the second soft pad 16. Sleeve the excavating member 17 into the fixing bolts 19 at the bottom of the second pipe pile 5, and fix the excavating member 17 with the fixing nut 18 and the second soft pad 16. The second soft pad 16 plays a role in increasing the friction of the fixing nut 18, making its fixation of the excavating member 17 more firm and preventing it from falling off. Apply pressure to the top of the second pipe pile 5 with a press to make it penetrate into the ground. The lower excavating member 17 can squeeze the soil around the pipe pile, increasing the compactness of the soil around the pipe pile and making the pipe pile more stable underground.

[0026] Refer to Figure 3 and Figure 4, wherein connectors 12 are provided at the lower end of the first pipe pile 1 and the upper end of the second pipe pile 5. A plurality of first connection grooves are formed on the adjacent sides of the two connectors 12. A plurality of connection bolts 13 are arranged inside the plurality of connection grooves. A connection nut 11 is threadedly connected to the outer periphery of the plurality of connection bolts 13. By inserting the connection bolts 13 into the first connection grooves on the connectors 12 and screwing the connection nuts 11 onto the connection bolts 13, the two connectors 12 on the first pipe pile 1 and the second pipe pile 5 are fixed, so that the first pipe pile 1 is connected to the second pipe pile 5, and the buried depth of the concrete pipe pile underground can be increased.

[0027] Refer to Figure 5 , wherein a first protective member 4 is provided on the outer wall of the adjacent ends of the first pipe pile 1 and the second pipe pile 5. A second protective member 6 is provided on the right side of the first protective member 4. Plug-in slots are formed at the front and rear ends on the left side of the second protective member 6. A plurality of plugs 15 are arranged inside the two plug-in slots. The left sides of the two plugs 15 are fixedly connected to the right end of the first protective member 4. First fixing grooves are formed inside the first protective member 4 and the second protective member 6. A first fixing member 9 is threadedly connected inside the first fixing groove. By docking the plug 15 on the first protective member 4 with the plug-in slot on the second protective member 6 and then rotating the first fixing member 9 into it to fix the first protective member 4 and the second protective member 6, the connection between the first pipe pile 1 and the second pipe pile 5 can be protected, avoiding the situation that the moisture in the soil corrodes the connection after the first pipe pile 1 and the second pipe pile 5 are buried underground.

[0028] Working principle: The excavation part 17 is sleeved into the fixing bolt 19 at the bottom of the second pipe pile 5, and the excavation part 17 is fixed with the fixing nut 18 and the second soft pad 16. The second soft pad 16 plays a role in increasing the friction of the fixing nut 18, making its fixation of the excavation part 17 more firm and preventing it from falling off. The top of the second pipe pile 5 is pressed with a press to make it penetrate deeper into the ground. The excavation part 17 below can squeeze the soil around the pipe pile, increasing the compactness of the soil around the pipe pile, making the pipe pile more stable underground, and preventing the soil from entering the hollow part inside the pipe pile, avoiding subsequent cleaning work. After the second pipe pile 5 is pressed to a certain length, the fixing groove two on the connecting part 12 is aligned with those on the first pipe pile 1 and the second pipe pile 5, and then the connecting part 12 is fixed to the first pipe pile 1 and the second pipe pile 5 with the second fixing part 10. The positioning rod 14 below the first pipe pile 1 is aligned with the connecting groove two on the second pipe pile 5 and inserted into it, so that the first pipe pile 1 and the second pipe pile 5 are spliced. Then, by inserting the connecting bolt 13 into the connecting groove one on the connecting part 12 and screwing the connecting nut 11 onto the connecting bolt 13, the two connecting parts 12 on the first pipe pile 1 and the second pipe pile 5 are fixed, so that the first pipe pile 1 and the second pipe pile 5 are connected, which can increase the buried depth of the concrete pipe pile underground. Then, the support part 2 is installed on the top of the mounting plate 3 through the mounting part 7 and the first soft pad 8. The support part 2 can fix the building materials installed on the first pipe pile 1. Because it is triangular in shape, it can prevent the building materials from shaking and tilting, etc.
