[0002] The foundation is the lowest load-bearing part of a building buried underground. Depending on the building's structure and soil conditions, various foundation types can be used, such as strip foundations, isolated foundations, mat foundations, box foundations, or pile foundations. Foundation construction begins with leveling the site, followed by excavation, laying the foundation pad, pouring or masonry the foundation, and finally backfilling with soil.

[0003] In existing technologies, during foundation construction, pile openings need to be set up on the foundation to embed concrete piles. However, after the pile openings are set up, the concrete piles cannot be immediately installed into them. To prevent construction workers from falling into the pile openings, the pile openings need to be temporarily covered. Usually, wooden boards or other boards are placed on the pile openings at the construction site to achieve safety protection. However, wooden boards are susceptible to being blown and shifted by the wind, meaning that the safety of the pile opening protection is not good.

They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Please see Figures 1 to 3 , Figure 15This invention provides a technical solution: a foundation construction equipment for building structures, including a pile pit protection frame 1. A plug tube 2 is fixed to the bottom end of the pile pit protection frame 1. An overlapping plate 3 is integrally formed at the bottom end of the pile pit protection frame 1. A diagonal brace 4 is fixed between the overlapping plate 3 and the pile pit protection frame 1. A column 5 is fixed to the surface of the diagonal brace 4. A caster wheel 6 is fixed to the end of the column 5 away from the diagonal brace 4. An assembly groove 16 is opened on the top surface of the pile pit protection frame 1. A pressure plate 31 is movably inserted into the bottom surface of the assembly groove 16. The pressure plate 31 penetrates the pile pit protection frame 1 and is inserted into the overlapping plate 3, pushing against a push block 22. A support plate 21 is fixed to one end of the push block 22. The support plate 21 is movably inserted into the outer ring surface of the overlapping plate 3, the top surface of the pressure plate 31 is fixed to the bottom surface of the pressure ring 32, the pressure ring 32 is movably inserted into the assembly groove 16, and the top of the pressure ring 32 is hinged with a cover plate 45; after the plug tube 2 is inserted into the pile opening, the pressure ring 32 is pressed down, which drives the pressure plate 31 to simultaneously push multiple push blocks 22. The push blocks 22 drive the support plate 21 to abut against the side wall of the pile opening, and the reinforced pile pit protection frame 1 is installed above the pile opening. The cover plate 45 is hinged to the top of the pressure ring 32 to cover the pipe opening of the pile pit protection frame 1 and complete the safety protection of the pile opening; this further solves the problem of poor safety of the existing pile opening protection structure and can provide safety protection for the pile opening.

[0040] Example 2

[0041] See attached document Figure 6 as well as Figure 12 Based on Embodiment 1, in order to achieve the limiting function of the overlapping plate 3 after overlapping the foundation, the outer ring surface of the overlapping plate 3 is provided with multiple storage grooves 9, and the bottom surface of the groove opening of the storage groove 9 is provided with a bottom groove 10. The storage groove 9 and the bottom groove 10 form an "L" shaped groove. An extension plate 11 is slidably connected inside the storage groove 9. A reserved hole 12 is provided at the end of the extension plate 11 extending to the outside of the storage groove 9. The reserved hole 12 is a "T" shaped round hole. A sliding groove 13 is provided on the top surface and the bottom surface of the extension plate 11. A stop block 14 is slidably connected inside the sliding groove 13. The stop block 14 is fixed to the surface of the storage groove 9. Rubber clips 15 are fixed on the top surface and the bottom surface of the end of the extension plate 11 extending to the inside of the storage groove 9. The rubber clips 15 are clamped between the extension plate 11 and the storage groove 9 to produce elastic deformation.

[0042] After the plug tube 2 is inserted into the pile opening, the overlapping plate 3 overlaps on the foundation. The extension plate 11 is pulled out from the receiving groove 9 until the stop block 14 blocks one end of the sliding groove 13. The grounding bolt is passed through the reserved hole 12 and fixed on the foundation. Since the extension plate 11 has an "L" shaped plate structure, the extension plate 11 will not be suspended. After multiple sets of extension plates 11 are pulled out and fixed on the foundation, the stability of the pile pit protection frame 1 installed on the pile opening is reinforced. After the extension plate 11 is pushed into the receiving groove 9, the rubber clamp 15 is clamped between the receiving groove 9 and the extension plate 11 to avoid the problem of the extension plate 11 sliding when there is no external force to pull the extension plate 11. This further solves the problem of poor safety of the existing pile opening protection structure and can protect the pile opening.

[0043] Example 3

[0044] See attached document Figure 13 Based on Embodiment 2, in order to enable the equipment to slide and transfer after being inverted, multiple diagonal braces 4 are provided. The multiple diagonal braces 4 are arranged at equal distances and of equal size along the outer ring surface of the pile pit protection frame 1. The column 5 is perpendicular to the plate 3, and an auxiliary support rod 7 is fixed between the column 5 and the diagonal braces 4.

[0045] When the pile pit protection frame 1 is removed from the pile opening and needs to be moved, the pile pit protection frame 1 is rotated 180 degrees and then supported on the foundation by the casters 6. The pile pit protection frame 1 can be pushed and moved. This further solves the problem of poor safety of the existing pile opening protection structure and can protect the pile opening.

[0046] Example 4

[0047] See attached document Figure 5 , Figures 7 to 11Based on Embodiment 3, in order to achieve the reinforcement effect after the plug tube 2 is inserted into the pile pit, the bottom surface of the assembly groove 16 is provided with multiple insertion ports 17, and the top surface of the overlapping plate 3 is provided with a positioning slot 18. The positioning slot 18 and the insertion port 17 correspond one-to-one, and the positioning slot 18 and the corresponding insertion port 17 are connected. The pressure plate 31 passes through the insertion port 17 and is inserted into the positioning slot 18. The side wall of the positioning slot 18 near the outer ring surface of the overlapping plate 3 is provided with a through hole 19, and the push block 22 is movably inserted into the through hole 19. One end of the push block 22 extending into the positioning slot 18 is provided with a slope 23, which faces the slot of the positioning slot 18. The other end of the push block 22 is fixed to the surface of the support plate 21. The surface of the push block 22 is provided with a through hole 24, and an elastic rubber band 25 is fixed to the surface of the through hole 24. The two ends of the elastic rubber band 25 are respectively fixed to two parallel side walls of the through hole 19. The pressure plate 31 is inserted into the positioning slot. After groove 18, push block 22 is pushed by pressure plate 31, elastic rubber band 25 is stretched and undergoes elastic deformation; the outer ring surface of overlapping plate 3 has a side groove 20, which is an arc-shaped groove, and support plate 21 is an arc-shaped plate. Support plate 21 is movably inserted into side groove 20, and the outer ring surface of support plate 21 has a locking groove 28. The inner ring surface of support plate 21 has two sets of positioning holes 26, and a traction rod 27 is movably inserted into the positioning holes 26. The rod is T-shaped, and a retaining ring is fitted at one end of the traction rod 27. The retaining ring is fixed in the slot of the positioning hole 26. The retaining ring limits one end of the traction rod 27 in the positioning hole 26. The inner ring surface of the support plate 21 has an insert groove 29. A rubber traction strip 30 is fixed on the surface of the insert groove 29. One end of the rubber traction strip 30 is fixed on the surface of the side groove 20. After the support plate 21 is pushed out of the side groove 20, the rubber traction strip 30 is tensioned and produces elastic deformation.

[0048] After the plug tube 2 is inserted into the pile opening, the pressure plate 31 is inserted into the assembly slot 16. After the pressure plate 31 is aligned with the corresponding positioning slot 18, the pressure ring 32 is pressed down until it is inserted into the assembly slot 16. At this time, the rubber support ring 34 is deformed by pressure and retracts into the embedding slot 33. During the descent of the pressure plate 31, the inclined surface 23 is squeezed to push the push block 22 into the through hole 19. When the push block 22 moves, the elastic rubber band 25 is stretched and deformed, and the push block 22 extends into the side groove 20, pushing the support plate 21 out of the side groove 20. The traction rod 27 guides the movement of the support plate 21, and the rubber traction strip 30 is stretched and deformed. Until the support plate 21 abuts against the side wall of the pile opening, the overlapping plate 3 is fixed in the pile opening, reinforcing the stability of the pile pit protection frame 1 installed after the pile opening; when the plug tube 2 needs to be removed from the pile opening, after the pressure ring 32 is pulled out from the assembly groove 16, when the pressure plate 31 no longer blocks the push block 22, the elastic rubber band 25 rebounds and drives the push block 22 to move into the positioning slot 18, and the push block 22 pulls the support plate 21 into the side groove, and the rubber traction strip 30 rebounds, which also plays a role in pushing the support plate 21 into the side groove 20; further solving the problem of poor safety of the existing pile opening protection structure, it can protect the pile opening.

[0049] Example 5

[0050] See attached document Figure 14 and Figure 17 Based on Embodiment 4, in order to limit the positioning of the pressure ring 32 after it is inserted into the assembly groove 16, the assembly groove 16 is an annular groove, and the height of the pressure ring 32 is greater than the height of the assembly groove 16. A second embedding groove 33 is provided on the bottom surface of the pressure ring 32. The second embedding groove 33 is an annular groove, and a rubber support ring 34 is fixed to the top surface of the second embedding groove 33. After the pressure ring 32 is inserted into the assembly groove 16, the rubber support ring 34 is clamped between the pressure ring 32 and the assembly groove 16, resulting in elastic deformation. Two elastic traction plates 37 are symmetrically fixed to the outer ring surface of the pressure ring 32. The elastic traction plate 37 has an "L"-shaped plate structure. The surface of the elastic traction plate 37 is fixed with a retaining strip 38, which is inserted into a second retaining groove 39. The second retaining groove 39 is an annular groove and is opened on the outer ring surface of the pile pit protection frame 1. The surface of the elastic traction plate 37 is provided with a snagging groove 35. The snagging groove 35 and the retaining strip 38 are symmetrically distributed about the plate body of the elastic traction plate 37. The surface of the snagging groove 35 is fixed with a pull ring 36. The top surface of the pressure ring 32 is provided with multiple snagging grooves 35, and the top surface of the snagging groove 35 is fixed with a pull ring 36.

[0051] After the pressure ring 32 is pushed into the assembly groove 16, the retaining strip 38 is inserted into the second retaining groove 39. In this way, the pressure ring 32 will not move upward. When it is necessary to remove the pressure ring 32 from the assembly groove 16, after inserting a finger into the third embedding groove 40, the pull rod 41 is squeezed to stretch the side plate of the elastic traction plate 37 to deform. The deformed elastic traction plate 37 pulls the retaining strip 38 out of the second retaining groove 39. This further solves the problem of poor safety of the existing pile opening protection structure and can protect the pile opening.

[0052] Example 6

[0053] Reference Figure 16 Based on Embodiment 5, in order to seal the top opening of the pile pit protection frame 1, a notch 42 is provided on the top surface of the pressure ring 32. A limiting shaft 43 is fixed between the two parallel sidewalls of the notch 42. The limiting shaft 43 moves through the swing handle 44. A cover plate 45 is fixed to one end of the swing handle 44. After the cover plate 45 is placed flat on the inner ring opening of the notch 42, the cover plate 45 seals the opening of the pile pit protection frame 1. A sealing ring 47 is fixed on the outer side of the cover plate 45. The sealing ring 47 is clamped between the cover plate 45 and the notch 42. Two finger grooves 48 are symmetrically opened on the surface of the cover plate 45. The finger grooves 48 are U-shaped grooves. A rubber gasket 49 is fixed on the sidewall of the finger grooves 48. The rubber gasket 49 is U-shaped strip. Multiple reflective warning strips 1 8 are fixed on the outer ring surface of the pile pit protection frame 1. A reflective warning strip 2 46 is fixed on the top surface of the cover plate 45.

[0054] After the pressure ring 32 is inserted into the assembly groove 16, the cover plate 45 covers the top of the pile pit protection frame 1, thus protecting the top opening of the pile pit protection frame 1. When it is necessary to open the cover plate 45, insert your fingers into the finger groove 48, pinch the rubber gasket 49 and pull the cover plate 45 upward to drive the swing handle 44 to rotate around the limit shaft 43. This further solves the problem of poor safety of the existing pile opening protection structure and can protect the pile opening.

[0055] Example 7

[0056] Based on Example 6, a construction process for building foundation construction equipment is proposed, which includes the following steps:

[0057] After inserting the plug tube 2 into the pile pit, the overlapping plate 3 overlaps on the foundation. The pressing ring 32 is pushed down and inserted into the assembly groove 16. The pressing ring 32 presses down on the pressing plate 31. The pressing plate 31 pushes the push block 22 to push the support plate 21 out of the side groove 20. The support plate 21 abuts against the side wall of the pile pit. The reinforced pile pit protection frame 1 is installed on the pile pit. After pulling the extension plate 11 out of the storage groove 9, the bolt rod is inserted into the foundation after passing through the reserved hole 12 to prevent the overlapping plate 3 from tilting or moving on the foundation.

[0058] Example 8

[0059] Based on Example 6, a method for using building foundation construction equipment is proposed, including the following steps:

[0060] Step 1: After the plug tube 2 is inserted into the pile opening, the overlapping plate 3 overlaps on the foundation. The extension plate 11 is pulled out from the receiving groove 9 until the stop block 14 blocks one end of the sliding groove 13. The grounding bolt is passed through the reserved hole 12 and fixed on the foundation. Since the extension plate 11 has an "L" shaped plate structure, the extension plate 11 will not be suspended. After multiple sets of extension plates 11 are pulled out and fixed on the foundation, the stability of the pile pit protection frame 1 installed on the pile opening is reinforced. After the extension plate 11 is pushed into the receiving groove 9, the rubber clamp 15 is clamped between the receiving groove 9 and the extension plate 11 to prevent the extension plate 11 from sliding when there is no external force to pull the extension plate 11.

[0061] Step Two: After the plug tube 2 is inserted into the pile opening, the pressure plate 31 is inserted into the assembly groove 16. After the pressure plate 31 is aligned with the corresponding positioning slot 18, the pressure ring 32 is pressed down until it is inserted into the assembly groove 16. At this time, the rubber support ring 34 is deformed by pressure and retracts into the embedding groove 33. During the descent of the pressure plate 31, the inclined surface 23 is squeezed to push the push block 22 into the through hole 19. When the push block 22 moves, the elastic rubber band 25 is stretched and deformed, and the push block 22 extends into the side groove 20, pushing the support plate 21 out of the side groove 20. The traction rod 27 guides the movement of the support plate 21. The rubber traction strip 30 is stretched and deformed until the support plate 21 abuts against the side wall of the pile opening, fixing the overlapping plate 3 in the pile opening and reinforcing the stability of the pile pit protection frame 1 after installation at the pile opening; when the plug tube 2 needs to be removed from the pile opening, after the pressure ring 32 is pulled out from the assembly groove 16, when the pressure plate 31 no longer blocks the push block 22, the elastic rubber band 25 rebounds and drives the push block 22 to move into the positioning slot 18, and the push block 22 pulls the support plate 21 into the side groove, and the rubber traction strip 30 rebounds, which also plays a role in pushing the support plate 21 into the side groove 20;

[0062] Step 3: After the pressure ring 32 is pushed into the assembly slot 16, the locking strip 38 is inserted into the second locking slot 39. In this way, the pressure ring 32 will not move upward. When it is necessary to remove the pressure ring 32 from the assembly slot 16, insert your finger into the third embedding slot 40 and squeeze the pull rod 41 to stretch the side plate of the elastic traction plate 37 to deform. The deformed elastic traction plate 37 will pull the locking strip 38 out of the second locking slot 39.

[0063] Step 4: After the pressure ring 32 is inserted into the assembly groove 16, the cover plate 45 covers the top of the pile pit protection frame 1 to protect the top pipe opening of the pile pit protection frame 1. When it is necessary to open the cover plate 45, insert your fingers into the finger groove 48, pinch the rubber pad 49 and pull the cover plate 45 upward to drive the swing handle 44 to rotate around the limit shaft 43.

[0064] Step 5: When the pile pit protection frame 1 is removed from the pile opening and needs to be moved, rotate the pile pit protection frame 1 180 degrees, and then support it on the foundation with the casters 6. Push the pile pit protection frame 1 to slide and move it.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
