Description

Technical Field

[0001] This utility model relates to the field of construction technology of interlocking piles in vertical shafts, and specifically to a device for detecting the verticality of pile holes in interlocking steel-concrete composite piles in vertical shafts. Background Technology

[0002] Interlocking piles are a type of foundation pit retaining structure in which piles interlock with each other. The piles are arranged alternately with one unreinforced plain concrete pile (Pile A) and one reinforced concrete pile (Pile B). During construction, pile A is constructed first, followed by pile B. Pile B is constructed before the initial setting of the concrete in pile A. The concrete at the intersection of adjacent piles A is cut away, thus achieving the interlocking effect.

[0003] Before construction, interlocking piles are typically drilled and concrete is poured using either full casing drilling or a combination of rotary drilling and impact drilling. During drilling, the verticality of the pile hole affects the subsequent pile formation effect. When the borehole tilts, it causes the entire interlocking pile to tilt, resulting in insufficient support force during shaft excavation, or the interlocking pile to deviate towards the center of the shaft. During shaft excavation, the deviated portion exposed in the shaft needs to be cut off, affecting construction quality, reducing construction efficiency, and increasing construction costs.

[0004] Utility model patent CN221571477U discloses a device for detecting the verticality of compacted pile boreholes, comprising an upper circular plate and a lower circular plate. The top of the lower circular plate is connected to four main circular rods. The top of the upper circular plate has four circular holes for the main circular rods to pass through. A winch is installed at the top of the upper circular plate. A limiting tube is embedded in the center of the upper circular plate. The winch's rope passes through the limiting tube and is connected to a plumb bob for detecting the verticality of the compacted pile borehole. A second screw is provided at the top of each main circular rod. The borehole has a threaded connection to a threaded post, and the top of the threaded post is connected to a secondary round rod with the same structure as the main round rod. Rectangular channels are provided on the sides of both the upper and lower round plates, and L-shaped adjusting components are installed inside these channels to fit against the inner wall of the compaction pile borehole. Before use, if the visual deviation is very small, or if precise testing is required, several secondary round rods can be assembled, and the distance between the upper and lower round plates can be adjusted. Then, a winch can be used to... The machine lays out the line, bringing the plumb bob as close as possible to the lower circular plate, but without contact. The four adjusting parts rest against the inner wall of the compaction pile hole. Small errors are amplified by the long pull rope, resulting in a much larger representation on the scale paper, facilitating subsequent accurate calculations. By changing the actual length of the upper and lower adjusting parts, the upper adjusting part is placed on the hole rock of the compaction pile, and the plumb bob is used to determine the tilt angle of the screen above the compaction pile. The lower circular plate is placed on the horizontal inner wall of the compaction pile hole, and the plumb bob is used to determine the tilt angle of the horizontal inner wall of the hole. In this patent, the upper and lower circular plates are connected by a main circular rod and a secondary circular rod, so that the relative position of the upper and lower circular plates in the vertical direction is fixed. That is, the landing point of the plumb bob from below the limiting tube on the lower circular plate is determined. No matter how the adjusting parts are adjusted, it will only drive the upper and lower circular plates to move synchronously in the horizontal direction, without affecting the position of the plumb bob relative to the lower circular plate. Therefore, it cannot be used to detect the verticality of the pile hole. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In one embodiment, see Figure 1 The present invention relates to a verticality detection device for a vertical shaft steel-concrete interlocking pile hole, comprising a support assembly, an upper monitoring assembly, and a lower monitoring assembly.

[0027] The support assembly includes a support frame 1, a leveling component 2 mounted on the support frame 1, a connecting rope 3 and a connecting cable 4 mounted on the support frame 1, and a leveling bubble 5 mounted on the support frame 1. The leveling component 2, under external force, pushes the support frame 1 to move, thereby adjusting the support frame 1 to be parallel to the horizontal plane. The upper monitoring assembly includes an upper monitoring disc 6 connected to the connecting rope 3, and multiple sets of first positioning components 7 equidistantly arranged along the circumference of the upper monitoring disc 6. The upper monitoring disc 6 has a graduated ring 8, and the first positioning components 7 have a first abutment plate 9. Under external force, the first positioning components 7 drive the first abutment plate 9 to move and abut against the inner wall of the pile hole. This ensures that the center of the upper monitoring plate 6 is concentric with the cross section of the pile hole along the plane of the upper monitoring plate 6; the connecting cable 4 slides through the upper monitoring plate 6; the lower monitoring assembly includes a lower monitoring plate 10 connected to the connecting cable 4, and multiple sets of second positioning members 11 equidistantly arranged along the circumference of the lower monitoring plate 10. A laser generator 12 is provided at the center of the lower monitoring plate 10, and a second abutment plate 13 is provided on the second positioning member 11. Under the action of external force, the second positioning member 11 drives the second abutment plate 13 to move and abut against the inner wall of the pile hole, thereby ensuring that the center of the lower monitoring plate 10 is concentric with the cross section of the pile hole along the plane of the lower monitoring plate 10.

[0028] Further, see Figure 2 The support frame 1 includes a support ring 101 and a support rod 102 disposed on the support ring 101. The connecting rope 3 and the connecting cable 4 are respectively connected to the support rod 102. The leveling component 2 includes a leveling rod 201 disposed circumferentially along the support ring 101 and a leveling column 202 rotatably disposed on the leveling rod 201.

[0031] In the above setup, the support ring 101 is installed on the ground outside the pile hole, and the support plate 203 is located on the ground. By rotating the leveling column 202, the leveling column 202 is moved under the action of the thread, thereby adjusting the distance between the leveling column 202 and the leveling rod 201. By referring to the position of the support ring 101 with the leveling bubble 5, the support ring 101 is adjusted to be parallel to the horizontal plane.

[0033] Preferably, four sets of branch ropes 14 are provided, and the four sets of branch ropes 14 are arranged circumferentially along the center of the upper monitoring plate 6.

[0034] Further, see Figure 5 The end of the connecting cable 4 away from the support rod 102 is provided with a branch cable 15. The branch cable 15 is connected to the lower monitoring plate 10. The connection point between the branch cable 15 and the lower monitoring plate 10 is located around the center of the lower monitoring plate 10, so that the projection of the connecting cable 4 in the vertical direction coincides with the center of the lower monitoring plate 10.

[0035] Preferably, four groups of splicing cables 15 are provided, and the four groups of splicing cables 15 are arranged circumferentially along the center of the lower monitoring plate 10.

[0036] Preferably, the support rod 102 is provided with a through hole 103, and the connecting cable 4 passes through the through hole 103 and is connected to the lower monitoring plate 10. The connecting cable 4 can be connected to an existing winch.

[0037] In the above setup, the connecting rope 3 is connected to the upper monitoring plate 6 via a split rope 14. When the connecting rope 3 is straightened, the upper monitoring plate 6 is kept parallel to the horizontal plane. The connecting cable 4 is connected to the lower monitoring plate 10 via a split cable 15. When the connecting cable 4 is straightened, the lower monitoring plate 10 is kept parallel to the horizontal plane.

[0038] Further, see Figure 3 , 4 The first positioning component 7 includes a first positioning plate 701 disposed at the bottom of the upper monitoring plate 6 and a first telescopic component 702 disposed on the first positioning plate 701. The distance from the end of the first telescopic component 702 to the center of the upper monitoring plate 6 is the same, and the first abutting plate 9 is connected to the end of the first telescopic component 702.

[0039] Preferably, the first telescopic member 702 is provided with four sets of first electric push rods. The first electric push rods are connected to the first positioning plate 701 by bolts, and the first abutment plate 9 is connected to the end of the first electric push rod.

[0040] Preferably, the first abutting plate 9 is an arc-shaped plate.

[0041] Further, see Figure 5 , 6 The second positioning component 11 includes a second positioning plate 1101 disposed at the bottom of the lower monitoring plate 10 and a second telescopic component 1102 disposed on the second positioning plate 1101. The distance from the end of the second telescopic component 1102 to the center of the lower monitoring plate 10 is the same, and the second abutment plate 13 is connected to the end of the second telescopic component 1102.

[0042] Preferably, the second telescopic member 1102 is provided with four sets of second electric push rods. The second electric push rods are connected to the second positioning plate 1101 by bolts, and the second abutment plate 13 is connected to the end of the second electric push rod.

[0043] Preferably, the second abutment plate 13 is an arc-shaped plate.

[0044] Preferably, the upper monitoring plate is provided with a sliding hole 16 for the connecting cable 4 to pass through.

[0045] It should be noted that both the first and second electric actuators are existing structures, and their internal structures and connection methods will not be modified; commonly used products can be used.

[0046] In the above setup, when the connecting rope 3 is taut, the upper monitoring plate 6 is parallel to the horizontal plane and located at the upper end of the pile hole near the ground. Multiple sets of first electric push rods simultaneously move the first abutment plate 9 towards the inner wall of the pile hole. Under the push of the first electric push rods, the first abutment plate 9 abuts against the inner wall of the pile hole, causing the center of the upper monitoring plate 6 to coincide with the center of the pile hole in the plane at that moment. When the connecting cable 4 is taut, the lower monitoring plate 10 is parallel to the horizontal plane and located at the lower end of the pile hole near the bottom of the pile hole. Multiple sets of second electric push rods simultaneously move the second abutment plate 13 towards the inner wall of the pile hole. Under the push of the second electric push rods, the second abutment plate 13 abuts against the inner wall of the pile hole, causing the center of the lower monitoring plate 10 to coincide with the center of the pile hole in the plane at that moment. At this time, the upper monitoring plate 6 and the lower monitoring plate 10 are located at two positions inside the pile hole, with a vertical gap between them.

[0047] In this embodiment, when detecting the verticality of the pile hole, the support ring 101 is installed on the ground outside the pile hole, and the support ring 101 is adjusted to be parallel to the horizontal plane by the leveling rod 201 and the leveling bubble 5. At this time, the upper monitoring plate 6 and the lower monitoring plate 10 are both located inside the pile hole, with the lower monitoring plate 10 located below the upper monitoring plate 6. The lower monitoring plate 10 is slowly lowered into the depth of the pile hole by the connecting cable 4. The depth of the lower monitoring plate 10 can be controlled according to the length of the connecting cable 4. For easy control, a length scale can be set on the connecting cable 4 for easy viewing. After the lower monitoring plate 10 reaches the predetermined position (the position is random or determined according to the detection requirements), the second electric push rod is activated to drive the second abutment plate 13 to move. After the second abutment plate 13 abuts against the hole wall of the pile hole, the position of the lower monitoring plate 10 inside the pile hole is fixed, and the excitation is turned on. The power supply of the light generator 12 is provided. The laser generator 12 adopts an existing structure that can emit laser beams. Then, the connecting cable 4 is loosened, and the first electric push rod is activated to drive the first abutment plate 9 to move. After the first abutment plate 9 abuts against the wall of the pile hole, the position of the upper monitoring plate 6 in the pile hole is fixed. At this time, the upper monitoring plate 6 and the lower monitoring plate 10 are located at two positions in the pile hole, and the centers of the upper monitoring plate 6 and the lower monitoring plate 10 coincide with the center of the pile hole on the plane. The laser beam emitted by the laser generator 12 falls on the intersection of the laser point position on the upper monitoring plate 6 and the scale ring 8. The verticality of the pile hole can be determined according to the positional relationship between the intersection point and the center of the upper monitoring plate 6. When the intersection point is offset from the center of the upper monitoring plate 6, the length from the intersection point to the center of the upper monitoring plate 6 is read through the scale ring 8, which is the offset.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
