Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a high-strength concrete pipe pile on-site construction device. Background Technology

[0002] Concrete pipe piles have been widely used in construction projects due to their advantages such as high single pile bearing capacity, high pile quality, and time-saving construction period. Prestressed concrete pipe piles are all produced in factories. Due to limitations in equipment, molds, and production capacity, the length of a single section of the finished pipe pile is generally 7 to 15 meters.

[0003] Currently, some existing concrete pipe piles are driven into the ground using a hammer-driven method, which involves driving the precast pile to a predetermined depth by hammering. Hammer-driven construction of pipe piles does not require pre-drilling of pile holes in the pile embedment area. However, this method of driving piles directly strikes the pile head, which not only easily breaks the pile head but also causes the pipe pile to shake during the impact, resulting in misalignment of the pipe pile.

[0004] Therefore, it is necessary to provide a new on-site construction device for high-strength concrete pipe piles to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 ,in Figure 1 A schematic diagram of a preferred embodiment of the high-strength concrete pipe pile on-site construction device provided by this utility model; Figure 2 for Figure 1 The diagram shows a structural schematic of the overall side view section. Figure 3 for Figure 2 A schematic diagram of the limiting structure shown in a frontal cross-section; Figure 4 for Figure 2The enlarged structural diagram of part A shown; the high-strength concrete pipe pile on-site construction device includes: a base plate 1; a positioning structure 2, which is fixed to the surface of the base plate 1 by bolts, the positioning structure 2 including a base 21 and a positioning cylinder 22, the base 21 being fixed to the center of the surface of the base plate 1 by bolts, and the base 21 also being fixed to the side wall of the bottom end of the positioning cylinder 22; and a protective structure 3, which is installed inside the positioning cylinder 22, the protective structure 3 including a sleeve. The sleeve 31 is installed inside the positioning cylinder 22, and the sliding groove 32 is correspondingly provided on the side walls at both ends of the sleeve 31. A limiting structure 5 is slidably connected inside the sleeve 31. The limiting structure 5 includes a limiting ring 51, a protrusion 52, an impact-receiving member 53, a movable groove 54, and a sleeve 55. The limiting ring 51 is fixed to the side wall of the impact-receiving member 53, and the limiting ring 51 and the impact-receiving member 53 are fixedly connected by a slider. The protrusion 52... Corresponding to the side wall of the limiting ring 51, the movable groove 54 is located at the center of the bottom surface of the impacted member 53, and the sleeve 55 is fixed to the bottom surface of the impacted member 53; the positioning plate 8 is fixed inside the movable groove 54; the adjusting structure 6 is rotatably connected to the inside of the impacted member 53, and the adjusting structure 6 includes a lead screw 61, a first bevel gear 62, a clamping plate 63, a support rod 64, a screw 65, and a second bevel gear 66, with the lead screw 61 passing through laterally. The protrusion 52 and the impact-receiving member 53, the first bevel gear 62 is fixed to the side wall of the middle section of the lead screw 61, the clamping plate 63 is slidably connected to the side wall of the middle section of the lead screw 61, the positioning plate 8 is rotatably connected to the side wall of the top end of the screw 65, the second bevel gear 66 is fixed to the top end of the screw 65, the support rod 64 is rotatably connected between the clamping plate 63 and the screw 65 through a connector; the striking structure 4 is slidably connected to the top end of the sleeve 31.

[0022] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 4 As shown, a through hole is provided in the center of the base plate 1, and the inner diameter of the through hole in the center of the base plate 1 corresponds to the diameter of the positioning cylinder 22. The distance between the base 21 and the bottom end of the positioning cylinder 22 is equal to the thickness of the base plate 1. The inner diameter of the positioning cylinder 22 corresponds to the diameter of the sleeve 31, and the inner diameter of the sleeve 31 is larger than the diameter of the pipe pile 7. The bottom end of the sleeve 31 slides inside the positioning cylinder 22, and the inside of the sleeve 31 is hollow. This allows the positioning cylinder 22 to restrict the position of the sleeve 31, and by placing the pipe pile 7 inside the sleeve 31, the pipe pile 7 can be kept vertical under the restriction of the sleeve 31.

[0023] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the striking structure 4 includes a positioning ring 41 and a striking element 42. The positioning ring 41 is fixed to the side wall of the striking element 42 by a slider. The striking element 42 is slidably connected to the inside of the sleeve 31. The striking element 42 is located directly above the impacted part 53, and the striking element 42 slides through the positioning ring 41 inside the sleeve 31. The length of the sleeve 31 is greater than the length of the pipe pile 7. The inner diameter of the sleeve 55 is greater than the maximum diameter of the pipe pile 7, and the diameter of the sleeve 55 is smaller than the inner diameter of the sleeve 31. The movable groove 54 is provided on the bottom surface of the impacted part 53 within the inner range of the sleeve 55. This allows the striking element 42 to be driven to squeeze the impacted part 53 by striking the striking element 42 inward through the top of the sleeve 31, thereby driving the pipe pile 7 deeper into the ground.

[0024] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the first bevel gear 62 and the second bevel gear 66 mesh with each other, and there are four support rods 64. The four support rods 64 are rhomboid and are rotatably connected to the screw 65 and the clamping plate 63 respectively through connecting parts. The two connecting parts on the side wall of the screw 65 are threadedly connected to the screw 65, and the connecting parts on the side wall of the clamping plate 63 are fixed. The threads at the upper and lower ends of the screw 65 are opposite. The side wall of the clamping plate 63 is arc-shaped, and the width of the clamping plate 63 is smaller than the width of the inner diameter of the pipe pile 7. This allows the first bevel gear 62 to drive the second bevel gear 66 to rotate by rotating the screw 61, thereby rotating the screw 65 and driving the connecting parts threaded on the side wall to move. This, in turn, drives the support rods 64 to support the clamping plate 63 to expand outward, thereby abutting against the inside of the top of the pipe pile 7, restricting the position of the pipe pile 7, and ensuring that the pipe pile 7 and the sleeve 31 are in a vertical state.

[0025] The working principle of the high-strength concrete pipe pile on-site construction device provided by this utility model is as follows:

[0026] In use, first place the base plate 1 on the ground, aligning the center point of the through hole in the center of the base plate 1 with the construction position. Then, insert the bottom end of the positioning cylinder 22 into the through hole, and make the base 21 abut against the surface of the base plate 1. Then, fix the base 21 with bolts, so that the positioning cylinder 22 is vertically fixed to the base plate 1. Then, hoist the pipe pile 7 to the positioning cylinder 22, and insert its bottom end from the top of the positioning cylinder 22 to abut against the ground. After straightening the pile, the sleeve 31 is inserted from the top of the pile 7, and the bottom end of the sleeve 31 is also inserted from the top of the positioning cylinder 22, so that the side wall of the bottom end of the sleeve 31 and the inner side wall of the positioning cylinder 22 are in contact with each other. Then, the position of the impact-bearing member 53 is adjusted by the sliding groove 32, so that the bottom end of the clamping plate 63 is inserted into the top of the pile 7. Following the direction of the clamping plate 63, the top of the pile 7 is moved into the inside of the sleeve 55, so that the sleeve 55 wraps around the outside of the top of the pile 7, and so that the... The top end of the pipe pile 7 abuts against the bottom surface of the impact-bearing member 53, initially restricting the position of the pipe pile 7. Then, by rotating the lead screw 61, the first bevel gear 62 drives the second bevel gear 66 to rotate, thereby causing the screw 65 to rotate, driving the threaded connector on the side wall to move, and further driving the support rod 64 to support the clamping plate 63 to expand outward, thereby abutting against the inside of the top end of the pipe pile 7, restricting the position of the pipe pile 7, so that the pipe pile 7 can be in a vertical state with the sleeve 31, and through... The position of the impacted member 53 is restricted by the contact between the clamping plate 63 and the pipe pile 7. Then, by external force, the striking member 42 is struck inward from the top of the sleeve 31, so that the striking member 42 can move down along the sliding groove 32, thereby generating downward pressure on the impacted member 53. This will squeeze the pipe pile 7, which is directly below the impacted member 53, into the ground, thereby realizing the construction of the pipe pile 7. This device has the advantage of preventing the pipe pile 7 from shaking and protecting the pile head from being broken during the hammering construction of the pipe pile 7.

[0027] Compared with related technologies, the high-strength concrete pipe pile on-site construction device provided by this utility model has the following beneficial effects:

[0028] This utility model provides a high-strength concrete pipe pile on-site construction device. First, the base plate 1 is laid on the construction point of the pipe pile 7, and the positioning structure 2 is fixed to the center of the surface of the base plate 1 with bolts, aligning the positioning structure 2 with the construction point of the pipe pile 7. Then, the pipe pile 7 is hoisted and inserted from the top of the positioning structure 2, and its position is straightened. Next, the protective structure 3 is inserted from the top of the pipe pile 7, with the bottom end of the protective structure 3 fitting against the inner diameter of the positioning structure 2, so that the positioning structure 2 supports and restricts the protective structure 3, ensuring the protective structure 3 is in a vertical position. Finally, the position of the limiting structure 5 is adjusted so that the limiting structure 5 can be adjusted... The clamping plate 63 in section structure 6 is inserted into the interior of the top of the pipe pile 7. By rotating the screw 61, the two clamping plates 63 are driven to expand outward, restricting the position of the pipe pile 7. Under the pressure of the clamping plates 63, the position of the pipe pile 7 is adjusted so that the top of the pipe pile 7 can be covered in the sleeve 55, and the top of the pipe pile 7 abuts against the center of the bottom surface of the limiting structure 5. Then, by striking the striking structure 4 with external force, the striking structure 4 applies pressure to the limiting structure 5, thereby driving the pipe pile 7 into the ground along the protective structure 3, thus realizing the construction of the pipe pile 7. This device has the advantage of preventing the pipe pile 7 from shaking and protecting the pile head from being broken during the hammering construction of the pipe pile 77.
