[0002] Reinforced concrete prestressed pipe piles are also called concrete pipe piles. Currently, concrete pipe piles are usually prefabricated in prefabricated component processing plants. After curing and reaching the designed strength, they are transported to the construction site and driven into the soil with a pile driver. Then, the pedestal beam (slab) foundation is poured on the top of the pile. The concrete pipe piles made in this way have greater structural strength and better performance.

[0003] However, the concrete pipe piles in the prior art usually need to be driven into the soil one by one. At this time, the pipe piles are in a single-point supported state, which can easily cause the concrete pipe piles to float and tilt under the squeezing force of the soil. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0022] During actual use, a pile driver is used to drive the concrete pipe pile 1 into the ground until the bottom end of the platform 2 contacts the ground. At this time, each group of auxiliary support piles 3 is also driven into the ground, and then one end of the anchor block 5 is extended from the anchor block installation groove 4, and the other end of the anchor block 5 stays in the anchor block installation groove 4, thereby preventing the auxiliary support pile 3 from floating up. Then, several groups of auxiliary support piles 3 provide multi-point support for the concrete pipe pile 1 through the platform 2, which can prevent the concrete pipe pile 1 from floating up and tilting.

[0023] Embodiment 2: On the basis of embodiment 1, in order to ensure that the anchor block 5 remains completely retracted in the anchor block installation groove 4 during transportation, the anchor block installation groove 4 is extended after the concrete pipe pile 1 is driven into the ground. One end of the anchor block 5 is provided with an inclined surface, and the other end of the anchor block 5 is provided with a pyramid. An elastic pull belt 7 is fixed between the end of the anchor block 5 with the inclined surface and the inner wall of the anchor block installation groove 4. A lower pressure rod groove 6 is provided on the surface of the auxiliary support pile 3, and one end of the lower pressure rod 8 is movably inserted in the lower pressure rod groove 6. A lower pressure rod hole 9 is provided on the surface of the table plate 2, and the other end of the lower pressure rod 8 is movably inserted in the lower pressure rod hole 9 and extends out of the lower pressure rod hole 9. A positioning groove 10 is provided on the surface of the lower pressure rod 8, and a positioning plate installation groove 11 is provided on the surface of the table plate 2. The positioning plate installation groove 11 One end of the positioning plate 12 is movably inserted in the middle, and the other end of the positioning plate 12 is movably inserted in the positioning groove 10. A limiting groove 13 is provided on the inner wall of the positioning plate mounting groove 11, and a limiting plate mounting groove 14 is provided on the surface of the positioning plate 12. One end of the limiting plate 15 is movably inserted in the limiting plate mounting groove 14, and the other end of the limiting plate 15 is movably inserted in the limiting groove 13. A limiting spring 16 is fixed between the limiting plate 15 and the inner wall of the limiting plate mounting groove 14. A driving rod window 17 is provided at the end of the positioning plate 12 extending out of the positioning plate mounting groove 11. The driving rod window 17 is connected with the limiting plate mounting groove 14. A driving rod 18 is slidably connected to the driving rod window 17. One end of the driving rod 18 is fixed on the surface of the limiting plate 15, and the other end of the driving rod 18 extends out of the driving rod window 17.

[0024] During transportation, the limiting spring 16 causes one end of the limiting plate 15 to stay in the limiting plate mounting groove 14 under its own elastic action, and the other end extends into the limiting groove 13, so that the positioning plate 12 is limited in the positioning plate mounting groove 11. At this time, one end of the positioning plate 12 is inserted into the positioning groove 10 opened on the surface of the lower pressure rod 8, so that the position of the lower pressure rod 8 in the lower pressure rod hole 9 is fixed. At this time, the anchor block 5 is in a state of being completely retracted into the anchor block mounting groove 4 under the pull of the elastic pull belt 7; when the concrete pipe pile 1 is driven into the ground, it will The lever 18 is moved toward the other end of the lever window 17, and the lever 18 drives the limit plate 15 to move in the same direction so that the limit plate 15 withdraws from the limit groove 13. Then the positioning plate 12 is pulled out from the positioning plate mounting groove 11, and the positioning plate 12 also withdraws from the positioning groove 10. Then, the down-pressing rod 8 is hammered with a hammer to make the down-pressing rod 8 move downward in the down-pressing rod groove 6. The bottom end of the down-pressing rod 8 contacts the inclined surface of the anchor block 5, thereby pushing one end of the anchor block 5 out of the anchor block mounting groove 4, so that the end of the anchor block 5 with a pyramid is inserted into the ground.

[0025] During actual use, a pile driver is used to drive the concrete pipe pile 1 into the ground until the bottom end of the platform 2 contacts the ground. At this time, each group of auxiliary support piles 3 is also driven into the ground, and then one end of the anchor block 5 is extended from the anchor block mounting groove 4, and the other end of the anchor block 5 stays in the anchor block mounting groove 4, thereby preventing the auxiliary support pile 3 from floating up. Then, several groups of auxiliary support piles 3 provide multi-point support for the concrete pipe pile 1 through the platform 2, which can prevent the concrete pipe pile 1 from floating up and tilting; during transportation, the limit spring 16, under the action of its own elasticity, makes one end of the limit plate 15 stay in the limit plate mounting groove 14, and the other end extends into the limit groove 13, so that the positioning plate 12 is limited in the positioning plate mounting groove 11. At this time, one end of the positioning plate 12 is inserted into the opening on the surface of the lower pressure rod 8 When the anchor block 5 is pushed into the ground, the push rod 18 is pushed toward the other end of the push rod window 17, and the push rod 18 drives the limit plate 15 to move in the same direction, so that the limit plate 15 withdraws from the limit groove 13, and then the positioning plate 12 is pulled out of the positioning plate mounting groove 11, and the positioning plate 12 also withdraws from the positioning groove 10, and then the push rod 8 is hammered with a hammer to make the push rod 8 move downward in the push rod groove 6, and the bottom end of the push rod 8 contacts the inclined surface of the anchor block 5, thereby pushing one end of the anchor block 5 out of the anchor block mounting groove 4, so that the end of the anchor block 5 with a pyramid is inserted into the ground.
