For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] See also Figures 1 to 4 As shown, a pile hole excavation protection device for anti-sliding piles includes a positioning seat 1 arranged around the pile hole, the positioning seat 1 is surrounded by four bases 2, and the positioning seat 1 forms a U-shaped structure. An inner support frame 3 is connected to the positioning seat 1, and the inner support frame 3 is connected to the positioning seat 1 through a suspension rope 4. The inner support frame 3 can be lowered into the pile hole, and the inner support frame 3 supports the poured concrete layer 5. The inner support frame 3 is also U-shaped and has a hollow area. Specifically, the inner support frame 3 is composed of four long frames connected in pairs, and each long frame is provided with an inner guard plate 6. At this time, the inner guard plates 6 are also four, so that the four inner guard plates 6 are arranged around the inner support frame 3, and each inner guard plate 6 is connected to the long frame. The spacing between the frames can be adjusted, for example: a central threaded hole and a limiting hole arranged around the central threaded hole are arranged on the long frame, and a limiting rod 7 is arranged on the inner guard plate 6. The number of the limiting rods 7 is the same as the limiting hole, so that each limiting rod 7 passes through the corresponding limiting hole, and at the same time, a push rod 8 is screwed in the central threaded hole, and a handle is fixed on the outer end of the push rod 8. When the push rod 8 is screwed, the spacing between the inner guard plate 6 and the excavated hole wall can be controlled, so that the inner guard plate 6 is close to the concrete layer on the inner wall of the pile hole. At this time, the inner guard plate is parallel to the concrete layer, so that the concrete layer can be protected. At the same time, the pile hole has a certain stability through the internal support of the inner support frame 3.

[0028] The bottom side and top side of the above-mentioned inner guard plate 6 are respectively provided with an upper locking support plate 9 and a lower locking support plate 10, and the structures of the two are the same, and the connection structures of the two with the inner guard plate 6 are also the same. After controlling the inner guard plate 6 to move toward the concrete layer, the upper and lower locking support plates are respectively against the completed concrete layer and the hole wall. At this time, the concrete layer waiting to solidify is located between the upper and lower locking support plates, which not only protects the concrete layer in the pile hole, but also increases the stability of the inner support frame 3.

[0029] In addition, the inner support frame 3 is provided with a conveying channel 11, which vertically penetrates the inner support frame 3. The conveying channel 11 is arranged around the central control area on the inner support frame. A hanger 12 is arranged on the positioning seat 1, and a feeding device is connected through the hanger 12. The excavated soil in the pile hole can be discharged through the feeding device. The feeding device includes a lifting bucket 13, and the lifting bucket 13 can pass through the conveying channel 11. At this time, the lifting bucket 13 and the conveying channel 11 are both arranged in an array around the hollow area on the inner support frame 3. The feeding device also includes a winder 14, which is connected to the lifting bucket 13 through a wire rope 15. After the construction workers in the pile hole pour the excavated soil into the lifting bucket, the wire rope 5 is wound up by the winder 14, so that the lifting bucket 13 can move upward. At this time, the lifting bucket 13 will move upward after passing through the conveying channel 11 until the lifting bucket 13 moves above the positioning seat, at which time the excavated soil in the lifting bucket 13 can be poured out;

[0030] The above-mentioned conveying channel 11 is in the shape of an elongated strip, and the conveying channel 11 is arranged on each elongated frame. The number of the lifting buckets 13 is the same as the number of the conveying channels 11. The lifting bucket 13 includes a shell having an upper opening, and the shell also has a bottom opening. A bottom door is hinged at the bottom opening. When the bottom door blocks the bottom opening, excavated soil can be filled into the shell. When the excavated soil needs to be discharged, the bottom door is opened, and the excavated soil in the shell will flow out of the shell.

[0031] In order to avoid safety hazards to the construction workers in the pile hole when the excavated soil is discharged, a guide plate 16 is hinged on the positioning seat 1, and the guide plate 16 can be flipped. Two supporting arms 17 are arranged below the guide plate 16, and the guide plate 16 can be placed on the two supporting arms 17. At this time, the guide plate 16 is located on the upward moving route of the lifting bucket 13. When the lifting bucket 13 moves upward, the guide plate 16 can be flipped upward. At this time, the guide plate 16 does not hinder the lifting bucket 13. When the lifting bucket 13 is located above the guide plate 16, the guide plate 13 is flipped downward to be placed on the two supporting arms 17. At this time, after opening the bottom side door, the free end of the bottom side door is placed on the guide plate 16 to realize the discharge of the excavated soil in the lifting bucket. At this time, the guide plate is tilted, and the excavated soil can slide along the tilt direction of the guide plate.

[0032] See also Figures 4 to 6As shown, the positioning seat 1 is provided with a guide groove 18, the bottom surface of the guide groove 18 is inclined, and the bottom surface of the guide groove 18 extends in the side opening direction. The hinge between the guide plate 16 and the positioning seat 1 is located in the guide groove 18. When the guide plate 16 is placed on the support arm 17, the guide plate 16 is in an inclined state. A blind hole 19 extending downward can be provided on the positioning seat 1. A push rod 20 with a telescopic function is provided in the blind hole 19. This push rod 20 can be a hydraulic push rod or an electric push rod. A top support arm 21 is fixed to the upper end of the push rod 20. The guide plate 16 can be controlled to flip upward by the extension of the push rod 20. When the push rod 20 is shortened, the guide plate 16 flips downward under the action of its own gravity until it is placed on the support arm 17 again.

[0033] To ensure the stability of the material guide plate 16 during the flipping process, a slide groove 22 is provided on the lower surface of the material guide plate 16, and the slide groove 22 extends to the material guide groove 18. At the same time, a sleeve wheel 23 is provided on the top support arm 21, and the sleeve wheel 23 is adapted in the slide groove 22. When the material guide plate 16 is flipped by the push rod 20, the sleeve wheel 23 moves in the slide groove 22, but cannot be moved out of the slide groove 22, thereby ensuring the stability of the flipping process of the material guide plate 16. At the same time, an orientation rod 24 can also be fixed on the top support arm 21. The orientation rod 24 is vertically connected to the top support arm 21 and extends downward. At the same time, a matching hole is provided on the positioning seat 1, and the orientation rod 24 is inserted into the matching hole. Such a setting can ensure the stability of the top support arm.

[0034] The utility model protects the poured concrete layer through the inner guard plate 6, and at the same time, the structure of the feeding device is arranged so that the feeding device will not affect the poured concrete layer, and also protects the construction personnel in the pile hole, and the soil and stone materials above the construction area may fall and affect the construction safety.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
