[0025] Now, the gravel feeding funnel with an outer lining for a micro steel pipe pile provided by the present utility model will be described.
[0026] As Figure 1 shown, the gravel feeding funnel with an outer lining for a micro steel pipe pile provided by the first embodiment of the present utility model includes a funnel body 10, a gate plate 20 and a limiting ring 30. The neck of the funnel body 10 is provided with a socket; the gate plate 20 is inserted into the socket at the neck of the funnel body 10; the limiting ring 30 is arranged below the neck of the funnel body 10 and is used to support at the mouth of the micro steel pipe pile 90.
[0027] The gravel feeding funnel lined on the outside of the micro steel pipe pile provided in this embodiment, compared with the prior art, during construction, after the micro steel pipe pile 90 is lowered and aligned, the bottom of the funnel body 10 is inserted into the mouth of the micro steel pipe pile 90, and the limiting ring 30 is used to support on the micro steel pipe pile 90. Then, the insertion depth of the gate plate 20 is adjusted so that the channel at the neck of the funnel body 10 is of a suitable size. After that, graded gravel is filled into the funnel body 10. Since the channel at the neck of the funnel body 10 is smaller than the inner diameter of the micro steel pipe pile 90, the graded gravel can slowly fall into the micro steel pipe pile 90 without accumulating in the middle of the micro steel pipe pile 90 to cause blockage, which is beneficial to the smooth progress of construction.
[0028] As Figures 1 to 3 shown, a specific implementation manner further provided by the present utility model based on the first implementation manner is as follows.
[0029] As Figure 2 shown, the outer side of the limiting ring 30 is of an inverted conical surface structure to be applicable to micro steel pipe piles 90 with different diameters.
[0030] As Figure 2 and Figure 3 shown, limiting pipes 40 are provided at both ends of the socket of the funnel body 10. The limiting pipes 40 are of a C-shaped cross-section structure to accommodate the edges of the gate plate 20. In this way, it is convenient for the gate plate 20 to be smoothly inserted into the socket and remain stable in the socket, avoiding movement during the feeding process.
[0031] As Figure 2 and Figure 3 shown, in some other specific embodiments, a fastening bolt 50 is provided on at least one of the limiting pipes 40 to fasten the gate plate 20 on the limiting pipe 40 to avoid movement of the gate plate 20 during the feeding process.
[0032] The limiting pipes 40 and the limiting ring 30 are both welded to the funnel body 10 to ensure stability.
[0033] As Figure 2 and Figure 3 shown, the front end of the gate plate 20 is provided with an inward concave arc edge to avoid forming too many narrow gaps with the inner wall of the funnel body 10, affecting the falling of the graded gravel, and the rear end is provided with a bending structure for easy insertion and extraction by the operator.
[0034] As Figure 2 shown, a vibrator 60 is provided on the funnel body 10 to apply vibration to the funnel body 10, reducing the possibility of the graded gravel getting stuck at the neck of the funnel body 10 and ensuring smooth feeding.
[0035] As Figure 2As shown, a rotating support 70 is provided on the funnel body 10. One end of the rotating support 70 is rotatably connected to the funnel body 10, and the other end is used to lap on the micro steel pipe pile 90. The vibrator 60 is provided on the rotating support 70. In this way, the vibration provided by the vibrator 60 can be applied to the funnel body 10 and the micro steel pipe pile 90 respectively, further reducing the possibility of graded broken stone getting stuck in the micro steel pipe pile 90 and ensuring smooth feeding.
[0036] As Figure 2 shown, a hoop 80 is provided at one end of the rotating support 70 for lapping on the micro steel pipe pile 90. The hoop 80 is rotatably connected to the rotating support 70 and is used to hoop on the micro steel pipe pile 90 to ensure the transmission of vibration and improve the stability of the funnel body 10 fixed on the micro steel pipe pile 90.
[0037] For convenient connection, a hoop 80 can also be provided at the other end of the rotating support 70, and the hoop 80 is connected to the neck of the funnel body 10.
[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
