DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] This embodiment includes two parallel support plates 2, which are long strips. The length of the support plates 2 is greater than the pile diameter of the bored pile 1, that is, the support plates 2 can span the entire bored pile 1. The two ends of the support plates 2 are fixed to the ground on both sides of the upper surface of the bored pile 1. The support plates 2 are used to support the lower bin 4 and the chute A8. The lower bin 4 is fixed on the two support plates 2. The lower bin 4 is located at the center of the bored pile 1. Extension plates 5 are provided outward on both sides of the upper end surface of the lower bin 4. The extension plates 5 are perpendicular to the support plates 2. The extension plates 5 are placed on the support plates 2 and fixed to the support plates 2 by bolts, thereby fixing the lower bin 4 and the support plates 2 together. The chute A8 is placed at the feed inlet position above the lower bin 4. The chute A8 is tilted upward. The upper part of the chute A8 is supported by a vertical support rod 9. The bottom of the support rod 9 is fixed to the ground near the bored pile 1. In order to make the support rod 9 support the chute A8 more stably, preferably, a bottom plate 20 is provided at the bottom of the support rod 9, and the bottom plate 20 is fixed to the ground by anchor bolts. Preferably, a handle 19 is provided in the middle of the lower bin 4, and the handle 19 is an inverted U-shape. More preferably, the inner width of the handle 19 is smaller than the outer width of the chute A8. The purpose of such a design is that the handle 19 can block the lower end of the chute A8, and when the chute A8 is fixed, the chute A8 can be supported by the handle 19. Concrete is transported to the upper part of the chute A8 by concrete conveying equipment, and the concrete slides down the chute A8 into the lower bin 4. The concrete conveying equipment can be a concrete mixer truck commonly used on the construction site, and the discharge port of the concrete mixer truck can be aligned with the chute A8.

[0021] The lower discharge port of the above-mentioned discharge bin 4 is integrally connected downwardly to the discharge pipe 6, and the discharge pipe 6 is connected downwardly to several sections of extension pipes 7. The discharge pipe 6 is gradually extended by the extension pipes 7 according to the depth of the manual bored pile 1. The connection between the discharge pipe 6 and the extension pipe 7 and the connection between the extension pipes 7 and the extension pipes 7 can be in various forms, such as threaded connection, sleeve connection, bolt connection, etc., and there is no special restriction here. In order to make the connection between the upper and lower pipes stable, preferably, the connection between the discharge pipe 6 and the extension pipe 7 and the connection between the extension pipe 7 and the extension pipe 7 is further strengthened by a cable tie 21 or a clamp or a clamp. In the attached figure of this embodiment, a cable tie 21 is used to further strengthen the connection.

[0022] The device of the present invention also includes a chute B10, which is used to pour concrete into the wall protection template of the artificial bored pile 1. The chute B10 is inclined downward, and the upper end side of the chute B10 is closed to prevent concrete from falling from the upper end. An upper cover plate 11 is provided on the upper part of the chute B10, and the upper cover plate 11 is formed integrally with the chute B10. A material receiving hole 12 is provided on the upper cover plate 11. The diameter of the material receiving hole 12 is slightly larger than the outer diameter of the extension tube 7. The extension tube 7 extends into the material receiving hole 12. Preferably, the diameter of the material receiving hole 12 is 5-10 cm larger than the outer diameter of the extension tube 7. A vertical rotating column 13 is fixedly connected downwardly to the bottom surface of the chute B10 directly below the material receiving hole 12. The rotating column 13 is inserted into a sleeve 14. The inner diameter of the sleeve 14 is equal to the diameter of the rotating column 13. The rotating column 13 can rotate in the sleeve 14. The vertical central axis of the rotating column 13 and the sleeve 14 are both located at the center of the pile of the artificial bored pile 1. The bottom end of the sleeve 14 is fixed on a base 15. The base 15 has a large weight and is used to support the rotating column 13 and the chute B10. To ensure the stability of the base 15, the base 15 is preferably a solid metal body, such as a solid cast iron cylindrical disk. The diameter of the base 15 can be preferably 40-60cm. A vertical support column 17 is fixed downwardly to the bottom surface of the lower part of the chute B10. The support column 17 is used to support the lower part of the chute B10. A universal wheel 18 is provided at the bottom end of the support column 17. The lower end of the chute B10 can extend into the casting space surrounded by the wall template. Handles 16 are provided on both sides of the lower part of the chute B10. The handles 16 are used by workers to pull the chute B10 to rotate. The workers grab the handles 16 to pull the chute B10 to rotate. When rotating, the rotating column 13 on the upper part of the chute B10 rotates in the sleeve 14, so that the chute B10 rotates to pour concrete into the template supported at the guard wall 3.

[0023] When the present invention is used, the lower material bin 4 is fixed in the middle of two parallel support plates 2, and then the two support plates 2 are fixed on the ground, so that the chute A8 is tilted downward, and the lower end of the chute A8 is placed on the feeding port above the lower material bin 4. The upper end of the chute A8 is fixed to the ground through the support rod 9, and then the base 15 is placed at the center of the bottom of the current excavation layer of the artificial bored pile 1, and the rotating column 13 is inserted into the sleeve 14 of the base 15, and then the extension pipe 7 is connected downward from the lower material pipe 6. The number of sections and the length of the extension pipe 7 are determined according to the depth of excavation, so that the bottom end of the extension pipe 7 can extend into the receiving hole 12, but does not touch the bottom surface of the chute B10, and the lower material pipe 6 and the extension pipe 7 are connected. The outer periphery of the connection position of the pipe 7 and the outer periphery of the connection position between the extension pipe 7 and the extension pipe 7 are further fastened and connected with the tie 21. After the connection is completed, the concrete is transported to the chute A8, and the concrete transporting equipment on the construction site is used to directly transport the concrete into the chute A8. For example, the discharge port of the concrete mixer truck is directly aimed at the upper part of the chute A8, and the concrete on the chute A8 slides down the chute A8 into the lower material bin 4, and then slides down to the chute B10 through the lower material bin 4, and then slides down into the retaining wall template through the chute B10. In this process, the worker pulls the chute B10 to rotate, and the chute B10 moves in a circle, realizing the concrete pouring of the retaining wall 3 of the manual bored pile 1. When the retaining wall 3 of the next layer needs to be poured, after the retaining wall template is supported, the extension pipe 7 is extended, and the retaining wall 3 is poured in the same way.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
