Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe piles, and specifically relates to a settlement-proof PHC concrete pipe pile. Background Technique

[0002] A pipe pile is a precast reinforced concrete engineering pile, mainly used in pile foundation engineering, which can improve the bearing capacity of the foundation and the subgrade. However, for common PHC concrete pipe piles, although they have high strength, due to their heavy weight, there is a possibility of getting out of track with the foundation environment after pile sinking. The large self-weight of the pipe pile results in a small contact area with the foundation environment, causing uncontrollable settlement.

[0003] A settlement-proof PHC concrete pipe pile provided in the publication number CN 218813672 U includes a pipe pile main body. A transmission shaft is rotatably installed at the center of the inner bottom of the pipe pile main body, and a plurality of openings are equidistantly formed on both sides of the pipe pile main body. A plurality of positioning mechanisms fixedly installed inside the pipe pile main body are equidistantly arranged on the outer edge surface of the transmission shaft. The positioning mechanism includes a driving gear fixedly installed on the transmission shaft. Eccentric linkage structures fixedly connected to the inner wall of the pipe pile main body are meshed on both sides of the driving gear, and two eccentric linkage structures are rotatably connected to positioning members arranged in the openings for inserting into the soil to limit the downward movement of the pipe pile main body. The positioning member includes a round shaft fixedly arranged on one side inside the opening. This settlement-proof PHC concrete pipe pile has a self-locking function, can increase the contact area with the foundation environment, prevent uncontrollable settlement of the pipe pile itself, and avoid affecting subsequent construction due to settlement, with strong practicability.

[0004] The above-mentioned existing technical solutions have the following defects: This settlement-proof PHC concrete pipe pile has slow pile sinking, is time-consuming and laborious, cannot increase the contact area, is prone to settlement, cannot self-lock and position, and the gears are prone to slipping and falling off. Therefore, the utility model provides a settlement-proof PHC concrete pipe pile to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a settlement-proof PHC concrete pipe pile to solve the problems of slow pile sinking, time-consuming and laborious, inability to increase the contact area, prone to settlement, inability to self-lock and position, and easy slipping and falling off of the gears in the above-mentioned background technique.

[0028] The main shaft 3 is installed inside the first through hole 2. A second through hole 15 is provided on the outer surface of the pipe pile body 1. A disc 4 is arranged on the outer side of the upper end of the main shaft 3. A right limiting arm 5 is installed at the right end of the disc 4, and a left limiting arm 6 is installed at the left end of the disc 4. Sleeves 7 are connected to the rear ends of both the right limiting arm 5 and the left limiting arm 6. A threaded rod 8 passes through the inside of the sleeve 7;

[0029] The driving sleeve gear 9 is installed at the lower end of the main shaft 3. A limiting block 17 is arranged inside the driving sleeve gear 9. The outer end of the driving sleeve gear 9 is connected to a toothed ring 10. A positioning plate 12 is arranged at the lower end of the toothed ring 10. A small gear 11 is connected to the lower end of the positioning plate 12. A positioning ring 13 is installed at the outer end of the small gear 11. A rectangular groove 14 is provided inside the positioning ring 13. A pointed head 16 is installed at the lower end of the pipe pile body 1.

[0030] Such as Figure 3 、 Figure 4 and Figure 5 As shown in

[0031] Such as Figure 1 、 Figure 2 and Figure 6 The lower end of the main shaft 3 is connected to the driving sleeve gear 9 in a clamping manner. The lower end of the driving sleeve gear 9 is connected to the toothed ring 10 in a meshing manner. The positioning plate 12 forms a rotating structure at the upper end of the positioning ring 13. The lower end of the positioning plate 12 is fixedly connected to the small gear 11. The outer end of the small gear 11 is connected to the rectangular groove 14 in a meshing manner. Five second through holes 15 are annularly provided on the outer surface of the pipe pile body 1. The second through holes 15 are arranged at equal intervals in the vertical direction of the pipe pile body 1. First, when it is necessary to drive a concrete pipe pile, use a crane to vertically place the pointed head 16 on the ground surface to complete pile sinking. After completion, the exposed end of the upper end of the main shaft 3 can be manually rotated, so that the main shaft 3 drives the driving sleeve gear 9 to rotate. Then, the outer end of the driving sleeve gear 9 meshes with the toothed ring 10. When the toothed ring 10 rotates, the positioning bolt at its lower end slides along with the rotation under the limitation of the rectangular groove 14. While the small gear 11 sleeved outside the positioning bolt rotates around the device, it meshes with the rack groove provided inside the positioning ring 13 and rotates itself, thereby driving the positioning plate 12 to turn outwards. Then, the positioning plate 12 is inserted into the soil through the second through hole 15. For the deployment of multiple positioning plates 12, the contact area between the pipe pile body 1 and the soil can be increased, realizing anti-settlement treatment and avoiding affecting the subsequent construction due to settlement. It has strong practicability. Moreover, the tip of the pointed head 16 is provided to make the pile sinking process faster, more convenient, time-saving and labor-saving.As shown, the right limit arm 5 and the left limit arm 6 are symmetrically arranged on the left and right with respect to the central axis of the disc 4, and the front end of the right limit arm 5 and the left limit arm 6 form a rotating structure. The inside of the sleeve 7 is connected to the threaded rod 8 in a threaded manner, and the threads at the left and right ends of the threaded rod 8 are arranged in opposite directions along the central axis. When the positioning plate 12 is screwed out, the threaded rod 8 can be rotated clockwise, and then the sleeves 7 arranged at the left and right ends of the threaded rod 8 both move inward. Then, the right limit arm 5 and the left limit arm 6 connected to the lower end of the sleeve 7 both move inward to engage the disc 4, locking and buckling the main shaft 3, so as to avoid the positioning plate 12 retracting due to gear slippage during use, which affects the use of the device.
