[0032] Example 1

[0033] See also Figure 1-Figure 2 This embodiment provides a micro steel pipe pile support device to solve the problem of poor anchoring ability between existing micro steel pipe piles and concrete.

[0034] The micro steel pipe pile supporting device includes a micro steel pipe pile 20 inserted into the borehole 10, a slot 21 is provided on the side wall of the micro steel pipe pile 20, a semicircular anchor plate 23 is hinged inside the slot 21, a slide groove 24 is provided on the anchor plate 23, an adjusting rod 30 is provided inside the micro steel pipe pile 20, a connecting rod 31 is fixedly connected to the lower end of the adjusting rod 30, and pins 32 that are fixedly connected to the corresponding slide grooves 24 are fixedly connected at both ends of the connecting rod 31.

[0035] In this embodiment, the adjusting rod 30 is moved downward to drive the anchor plate 23 to flip outward, and the anchor plate 23 is embedded in the concrete 40 to improve the anchoring of the micro steel pipe pile 20 and the concrete 40 .

[0036] It should be noted that the micro steel pipe pile 20 is coaxially arranged with the borehole 10, the slot 21 is formed on the side wall of the micro steel pipe pile 20, and the slot 21 extends along the axis of the micro steel pipe pile 20, the slot 21 is evenly distributed along the circumference of the micro steel pipe pile 20, the semicircular anchor plate 23 is rotatably hinged inside the slot 21, the rotating shaft 22 of the anchor plate 23 is fixed inside the slot 21, and the rotating shaft 22 is perpendicular to the axis of the micro steel pipe pile, and the slide groove 24 is arranged along the radial direction of the anchor plate 23.

[0037] In addition, the adjusting rod 30 is arranged coaxially with the micro steel pipe pile 20, and the anchor plates 23 are symmetrically arranged on both sides of the adjusting rod 30. A limiting rod 33 is fixedly connected to the top of the adjusting rod 30, and the limiting rod 33 is arranged along the diameter direction of the micro steel pipe pile 20. At the same time, both ends of the limiting rod 33 are abutted against the inner wall of the micro steel pipe pile 20. The limiting rod 33 is used to keep the adjusting rod 30 coaxial with the micro steel pipe pile 20. A circular boss 25 is fixedly connected to the inner wall of the micro steel pipe pile 20. The boss 25 is arranged below the limiting rod 33 to support the limiting rod 33 to limit the downward moving distance of the adjusting rod 30.

[0038] In addition, the connecting rod 31 is fixed to the bottom of the adjusting rod 30, and the connecting rod 31 and the adjusting rod 30 are kept vertically arranged, the pin 32 is fixed to the end of the connecting rod 31, and the pin 32 and the rotating shaft 22 of the anchor plate 23 are kept parallelly arranged, and the pin 32 can be slidably engaged with the inside of the slide groove 24, and the pin 32 is used to push the anchor plate 23 to rotate.

[0039] When in use, the micro steel pipe pile 20 is first inserted into the borehole 10, and then the adjusting rod 30 is moved downward to flip the anchor plate 23 to the outside of the micro steel pipe pile 20. When the circumference of the straight part of the anchor plate 23 is in a horizontal state, the limit rod 33 overlaps the boss 25, and then concrete 40 is poured into the micro steel pipe pile 20 and the borehole 10 at the same time. The anchor plate 23 is embedded in the concrete 40 to strengthen the anchoring of the micro steel pipe pile 20 and the concrete 40.
