Technical Field

[0001] This application relates to the field of concrete pouring technology, and in particular to a concrete pouring device for pile foundation construction. Background Technology

[0002] In the construction of building pile foundations, the concrete pouring after the pile hole is formed and the reinforcing cage is placed is a key step in the formation of the pile foundation. The tremie pipe pouring method is one of the most commonly used methods for building pile foundation pouring. When installing the tremie pipe, a crane is used to connect the tremie pipe section by section using threaded connections and other methods and hoist it into the pile hole. Then, the concrete is poured into the pile hole through the funnel at the top of the tremie pipe. As the concrete is poured, the tremie pipe is gradually lifted and removed to complete the pouring.

[0003] Currently, there is no limit to the guide pipe during the pouring process. If the guide pipe shakes or deviates during the pouring process, it will directly affect the strength of the poured concrete and threaten the quality of the pile. Therefore, there is still room for improvement. Summary of the Invention

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a concrete pouring device for pile foundation construction, referring to... Figure 1 It includes a funnel 1 and a guide tube 3 installed below the funnel 1 and inserted into the pile hole 2; the bottom of the funnel 1 is fixed with a discharge port 11 inserted into the guide tube 3, and a mounting ring 111 is fixed on the side wall of the discharge port 11. The mounting ring 111 abuts against the upper part of the guide tube 3, and the mounting ring 111 is positioned on the guide tube 3 by a number of circumferentially arranged mounting bolts.

[0028] Reference Figure 1 The positioning mechanism 4, which is a positioning guide tube 3 installed outside the pile hole 2, includes a support frame 41 that is positioned outside the pile hole 2 by a spiral ground pile and a scaled sliding ruler 42. The sliding ruler 42 is set at intervals on both sides of the guide tube 3, and the sliding ruler 42 is slidably connected to the corresponding position on the support frame 41. The spiral ground pile is suitable for temporary installation in sandy soil and other places.

[0029] Reference Figure 1 , 2 The bottom of the sliding ruler 42 is fixed with a dovetail-shaped connecting slider 421. The support frame 41 is provided with a groove 411 for the connecting slider 421 to slide. The sliding rulers 42 at intervals are respectively fixed with extension plates 422 on opposite sides. The extension plates 422 are fixed to the support frame 41 by fixing bolts 5. After adjusting the relative position of the sliding ruler 42 and the guide tube 3, the extension plates 422 can be positioned at the corresponding position of the support frame 41 to perform preliminary positioning of the guide tube 3.

[0030] Reference Figure 1 , 3 The positioning mechanism 4 also includes a limiting plate 43, which is fixed between the ends of the relative sliding rulers 42 near the conduit 3 and abuts against the side wall of the conduit 3. An arc groove 431 that cooperates with the side wall of the conduit 3 is provided on the side wall of the limiting plate 43 near the conduit 3, making it easier for the limiting plate 43 to position the conduit 3.

[0031] Reference Figure 1 , 4 The positioning mechanism 4 also includes a cam 44. A control motor 7 is fixed on the support frame 41. A control shaft 8 is fixed at the bottom of the output shaft of the control motor 7. The control shaft 8 is rotatably connected to the corresponding position on the support frame 41. Opposite abutment plates 81 are fixed on the control shaft 8. The opposite abutment plates 81 abut against the upper and lower ends of the corresponding position on the support frame 41, respectively, and play the role of vertically positioning the control shaft 8. The cam 44 is longitudinally spaced on the control shaft 8.

[0032] Reference Figure 1 , 3 The positioning mechanism 4 also includes a movable rod 45 and a positioning plate 46. A vertically extending fixed plate 10 is fixed on the support frame 41 between the cam 44 and the guide tube 3. The movable rod 45 passes through and is movably connected to the fixed plate 10. The positioning plate 46 is fixed to the end of the movable rod 45 near the guide tube 3 and abuts against the side wall of the guide tube 3. The positioning plate 46 is arc-shaped to match the side wall of the guide tube 3, which can increase the contact area with the side wall of the guide tube 3 and improve the stability of positioning the guide tube 3.

[0033] Reference Figure 1 The other end of the movable rod 45 is fixed with an arc-shaped protrusion 451 that abuts against the cam 44; a connecting spring 6 is sleeved and fixed on the movable rod 45; a circular plate 452 is fixed on one side of the movable rod 45 located on the arc-shaped protrusion 451; one end of the connecting spring 6 abuts against the fixed plate 10, and the other end abuts against the circular plate 452; pushing the movable rod 45 to slide on the fixed plate 10, the guide positioning plate 46 moves stably and abuts against the side wall of the guide tube 3, reducing the unstable phenomena such as shaking and displacement of the guide tube 3 during the pouring process; under the elastic force of the connecting spring 6, it helps the positioning plate 46 to reset.

[0034] Reference Figure 1 , 4 The cam 44 rotates and abuts against the arc-shaped protrusion 451. The rotation of the control shaft 8 and the cam 44 is positioned by a locking element. The locking element is a locking bolt 82 that is threaded to the upper abutment plate 81 and positioned on the support frame 41. When the control shaft 8 rotates, the abutment plate 81 can be fixed to the corresponding position on the support frame 41 by the locking bolt 82 to achieve the purpose of positioning the rotated control shaft 8.

[0035] Reference Figure 1A linkage plate 9 is fixed between the spaced positioning plates 46, and the spaced movable rods 45 are all fixed on the linkage plate 9. By setting the positioning plates 46 and the limiting plates 43, multiple positioning points are added in the longitudinal extension direction of the guide tube 3, which improves the positioning effect of the guide tube 3, maintains the stability of the guide tube 3 during the pouring process, and reduces unstable phenomena such as shaking and displacement of the guide tube 3 during the pouring process.

[0036] The working process for this application is as follows: After placing the guide tube 3, make the limiting plate 43 abut against the corresponding two sides of the guide tube 3. The scale line of the sliding ruler 42 can be observed from the front and rear ends using the front and rear intervals of the sliding ruler 42. Keep the relative sliding rulers 42 on both sides of the guide tube 3 at the same distance, and then make the guide tube 3 at the vertical center line of the pile hole 2.

[0037] Then, by controlling the motor 7 to drive the control shaft 8 to rotate, the cam 44 abuts against the arc-shaped protrusion 451, pushing the movable rod 45 and the positioning plate 46 to abut against the side wall of the guide tube 3. Then, the locking bolt 82 is used to fix the abutment plate 81 to fix the control shaft 8 so that it no longer rotates, thereby achieving the purpose of stabilizing the positioning of the guide tube 3.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
