Technical Field

[0001] This invention relates to pile foundation construction, and in particular to a semi-automatic adjustable size correction device for splicing irregular square piles and its construction method. Background Technology

[0002] Due to the rapid development of the construction industry, the requirements for construction quality are becoming increasingly stringent. If a pile does not reach the designed depth during construction, the precast piles need to be connected one by one and driven downwards until they reach the designed depth.

[0003] Connecting the top of the previous pile to the bottom of the next pile usually requires manual alignment of the connector at the bottom of the next pile with the clip at the top of the previous pile. This process is time-consuming and labor-intensive, and gaps are prone to appearing at the pile joint. This directly affects the efficiency and safety of the pile joint construction. Furthermore, gaps at the pile joint can affect the verticality of the pile, aggravate soil erosion at the pile joint, and thus affect the load-bearing capacity and durability of the entire structure, thereby affecting the construction progress and increasing the difficulty and cost of construction. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, thereby providing a semi-automatic adjustable size correction device for irregular square pile splicing and its construction method, so as to ensure the quality and accuracy of irregular square pile correction and splicing.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] See Figures 1-5 This embodiment provides a semi-automatic adjustable size correction irregular square pile splicing device, which mainly consists of an upper device body 2, a connecting rod 6 and a lower device body 13. The upper device body 2 and the lower device body 13 have the same structure.

[0035] The upper device body 2 mainly consists of a main body plate 201, a fixed plate 202, an operating plate 203, and a movable plate 8. All components—main body plate 201, fixed plate 202, operating plate 203, and movable plate 8—are rectangular and vertically arranged. The fixed plate 202 and operating plate 203 are vertically welded to both ends of the main body plate 201. The movable plate 8 is perpendicular to the main body plate 201 and positioned between the fixed plate 202 and the operating plate 203. The movable plate 8 is slidably connected to the main body plate 201 via a sliding structure consisting of sliding grooves 9 and sliding rods 10. The main body plate 201 has three horizontal sliding grooves 9. Three sliding rods 10 are installed at one end of the movable plate 10, passing through and slidably connecting with the sliding grooves 9. Limiting nuts 12 are installed on the sliding rods 10 outside the sliding grooves 9. The limiting nuts 12 on the sliding rods 10 allow for free assembly of the main body plate 201 and the movable plate 8.

[0036] A spring assembly is provided between the movable plate 8 and the operating plate 203. The spring assembly consists of compression springs 3, with both ends of multiple compression springs 3 connected to the movable plate 8 and the operating plate 203, respectively. The compression springs 3 are evenly distributed along the inner walls of the movable plate 8 and the operating plate 203. The compression springs 3 push the movable plate 8 to move along the slide groove 9, and the thrust of the compression springs 3 is evenly distributed on the movable plate 8 to prevent jamming.

[0037] An adjustment mechanism is provided between the movable plate 8 and the operating plate 203. The adjustment mechanism mainly consists of a pulley block 4, a handwheel 5, and a transmission rod 501. The pulley block 4 consists of a first pulley 401, a second pulley 402, a third pulley 403, and a steel wire rope 7. The first pulley 401 is installed on the surface of the movable plate 8 away from the fixed plate 202, and the second pulley 402 and the third pulley 403 are installed on the inner surface of the operating plate 203. One end of the steel wire rope 7 is fixedly connected to the operating plate 203, and the other end of the steel wire rope 7 passes around the first pulley 401 and the second pulley 402 and is wound around the third pulley 403.

[0038] The axle of the third pulley 403 is connected to one end of the transmission rod 501. The other end of the transmission rod 501 passes through the operating plate 203 and is fitted with a handwheel 5. A ratchet and pawl assembly (not shown in the figure) is installed between the transmission rod 501 and the operating plate 203. The ratchet and pawl assembly is used for positioning the transmission rod 501. Rotating the handwheel 5 in the forward direction causes the transmission rod 501 and the third pulley 403 to rotate in the forward direction, tightening the wire rope 7. The movable plate 8 compresses the spring 3 and moves towards the operating plate 203. Rotating the handwheel 5 in the reverse direction loosens the wire rope 7. The movable plate 8 moves towards the fixed plate 202 under the action of the spring 3, thereby engaging and pressing the irregular square pile 1.

[0039] The upper device body 2 and the lower device body 13 are connected by a connecting assembly consisting of a connecting rod 6 and an adjusting bearing. The upper and lower parts of the connecting rod 6 are threaded. One end of the fixing plate 202 of the main body plate 201 of the lower device body 13 has a threaded hole, and the lower part of the connecting rod 6 is installed in the threaded hole of the fixing plate 202. One end of the fixing plate 202 of the main body plate 201 of the upper device body 2 has a through hole, and adjusting bearings are installed at both ends of the through hole. The upper part of the connecting rod 6 passes through the adjusting bearing and the through hole. Positioning nuts 601 are screwed onto the connecting rod 6 above and below the main body plate 201 of the upper device body 2. In use, the lower device body 13 remains stationary, while the upper device body 2 rotates, causing the upper device body 2 and the lower device body 13 to overlap in the vertical direction. To facilitate rotation and operation of the upper device body 2, a handle 11 is installed on the outer surface of the operating plate 203.

[0040] The construction method of the above-mentioned semi-automatic adjustment and correction device for irregular square pile splicing shall be carried out according to the following steps ( Figure 6 (as shown)

[0041] S1. Fix the initial section of the irregular square pile and install the main body of the lower device.

[0042] After the initial irregular square pile 1 is driven into the ground, and the main body plate 201, fixing plate 202, compression spring 3 and movable plate 8 of the lower device body 13 are assembled, rotate the handwheel 5 in the forward direction to tighten the wire rope 7, and retract the movable plate 8 to the outermost end of the slide groove 9. Then, put the main body plate 201, fixing plate 202 and movable plate 8 of the lower device body 13 on the top of the initial irregular square pile 1. Rotate the handwheel 5 in the reverse direction to loosen the wire rope 7. The compression spring 3 pushes the movable plate onto the initial irregular square pile 1 and locks it in place. Install the connecting rod 6 on the lower device body 13, and install the upper device body 2 on the upper part of the connecting rod 6.

[0043] S2, Second Section: Fixing of Irregular Square Piles

[0044] Lift the second section of the irregular square pile 1, rotate the handwheel 5 of the upper device body 2 in the forward direction, and the third pulley 403 winds the steel wire rope 7 to retract the movable plate 8 to the outermost end of the slide groove 9. The upper part of the upper device body 2 is fitted onto the lower end of the second section of the irregular square pile 1. Release the handwheel 5, and the compression spring 3 pushes the movable plate 8 onto the second section of the irregular square pile 1 and locks it in place. Rotate the handle 11 of the upper device body 2 to adjust the angle of the upper device body 2 so that it drives the second section of the irregular square pile 1 to be at the same angle as the first section of the irregular square pile 1.

[0045] S1, Equipment Dismantling

[0046] After the splicing of the irregular square pile 1 is completed, rotate the handwheel 5 of the upper device body 2 in the forward direction. The wire rope 7 will retract the movable plate 8 to the outermost end of the slide groove 9. The movable plate 8 will release the second section of the irregular square pile 1 so that it is no longer stuck. Then, rotate the handle 11 on the side of the upper device body 2 to remove it from the connecting rod 6. Rotate the connecting rod 6 to remove it from the lower device body 13. Rotate the handwheel 5 of the lower device body 13 and wind the wire rope 7 to retract the movable plate 8 to the outermost end of the slide groove 9. The movable plate 8 will release the first section of the irregular square pile 1 so that it is no longer stuck.

[0047] S4. Repeat steps S1-S3 to splice the next set of irregular square piles 1. After the construction of the irregular square pile splice 1 is completed, if continuous construction is required, the connecting rod 6 can be rotated to remove it from the main body 2 of the lower device. Subsequent construction only needs to be reconnected to facilitate the continuity and convenience of construction.
