Abstract
Description
Technical Field
[0001] This utility model relates to the field of vertical shaft interlocking pile construction technology, specifically to a drilling positioning device for vertical shaft steel-concrete interlocking piles. 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, piles A are constructed first, followed by piles B. Pile B is constructed before the initial setting of the concrete in piles A. The concrete at the intersection of adjacent piles A is cut away, thus achieving the interlocking effect.
[0003] Before construction, interlocking piles in vertical shafts are typically drilled using full casing or a combination of rotary drilling and impact drilling, followed by concrete pouring. Since the vertical shaft is circular, the interlocking piles are distributed in a circular pattern after construction. During the drilling process, it is necessary to ensure that the pile holes of each group of A piles and each group of B piles are located on the same ring to guarantee construction quality. When constructing A piles, the positions of the two groups of A piles need to be staggered and constructed first, while the positions of the B piles are staggered. During the drilling process, the pile holes of the two groups of A piles also need to be drilled first, and then the pile holes of B piles need to be drilled between the two groups of A piles. Therefore, it is necessary to locate the positions of the pile holes of A piles and B piles. If the pile hole positions are offset, it is easy to cause a loss of interlocking force between A piles and B piles, which may seriously affect the quality of the entire interlocking pile.

[0022] 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.
[0023] In one embodiment, see Figure 1 The present invention relates to a drilling positioning device for vertical shaft steel-concrete interlocking piles, comprising an orientation component and a positioning component.
[0024] The orientation component includes a support platform 1, an orientation component 2 rotatably mounted on the support platform 1, a fixing rod 3 at the lower end of the support platform 1, an adjusting plate 4 at the upper end of the support platform 1, a first leveling bubble 5 on the adjusting plate 4, a leveling component 6 between the adjusting plate 4 and the support platform 1, and an angle reference component 7 on the adjusting plate 4; a laser rangefinder 8 is mounted on the orientation component 2; the positioning component includes a positioning plate 9, a connecting rod 10 mounted on the positioning plate 9, and a second leveling bubble 11 on the positioning plate 9.
[0025] Further, see Figure 2 The fixing rod 3 is vertically set at the center of the support platform 1. The leveling component 6 includes multiple sets of leveling rods 601. The leveling rods 601 are set on the support platform 1 by threads 14. The multiple sets of leveling rods 601 are equidistantly arranged along the circumference of the support platform 1.
[0026] Preferably, the end of the fixing rod 3 away from the support platform 1 is provided with a pointed end 12.
[0027] Preferably, the support platform 1 has a disc-shaped structure, and the support platform 1 is provided with four sets of screw holes 13, and the leveling rod 601 is provided with threads 14.
[0028] Further, see Figure 3The bottom end of the adjusting plate 4 is provided with a hinge sleeve 15; the top end of the support platform 1 is provided with a hinge ball 16. The hinge sleeve 15 and the hinge ball 16 are rotatably connected, and the adjusting plate 4 and the support platform 1 are concentrically arranged.
[0029] Preferably, the adjusting plate 4 has a circular structure, and the hinge sleeve 15 is located at the center of the adjusting plate 4.
[0030] Preferably, the hinge ball 16 is located at the center of the support platform 1, and the hinge ball 16 is in clearance fit with the hinge sleeve 15, which is formed by cutting off one-third of a hollow sphere.
[0031] In the above configuration, the support platform 1 and the adjusting plate 4 are connected by the hinge sleeve 15 and the hinge ball 16, and the adjusting plate 4 can rotate along the hinge ball 16. The rotating leveling rod 601 moves up or down under the action of the thread 14, so that the leveling rod 601 abuts against the adjusting plate 4. By referring to the first level bubble, the adjusting rod 601 at different positions can be adjusted to make the adjusting plate 4 parallel to the horizontal plane.
[0032] Further, see Figure 4 The angle reference component 7 includes a scale ring 701 and multiple sets of scale lines 702 set on the adjustment plate 4, and the included angle between adjacent scale lines 702 is consistent.
[0033] Preferably, the angle between adjacent scale lines 702 is 10°.
[0034] Further, see Figure 5 The directional component 2 includes a directional disk 201, on which a reference line 17 is provided. The directional disk 201 is concentrically set with the adjustment plate 4. The projection of the emitting end of the laser rangefinder 8 in the vertical direction coincides with the center of the directional disk 201.
[0035] Preferably, the directional disc 201 has a circular structure, with a rotating shaft 18 at the bottom center of the directional disc 201, and a rotating hole 19 at the top center of the adjusting plate 4. A bearing 20 is installed inside the rotating hole 19, and the rotating shaft 18 is fixedly connected to the inner ring of the bearing 20.
[0036] Preferably, the reference line 17 extends from the center of the upper end face of the orientation disk 201 to the side wall, and the reference line 17 is red.
[0037] Preferably, the laser rangefinder 8 is a laser rangefinder from existing equipment.
[0038] Further, see Figure 1 Positioning plate 9 is provided with positioning line 21.
[0039] Preferably, the positioning line 21 is located at the center of the positioning plate 9.
[0040] In the above setup, by rotating the orientation disk 201, the reference line 17 intersects with the scale line 702, and the laser rangefinder is activated to emit a laser line. The direction of the laser line is the line emanating from the center of the circular vertical shaft interlocking pile, used to determine the orientation of the center of one group of interlocking piles (pile A or pile B) relative to the center of the circle. Based on the diameter of the circular interlocking pile, the distance H from the center of the interlocking pile to the center of the circle can be determined. This distance H is determined by the laser rangefinder in conjunction with the positioning plate 9. The positioning plate 9 is inserted into the ground through the plug rod 10 to block the laser beam, leaving a laser point on the positioning plate 9. At this time, the vertical projection of the laser point is on the circle formed by the centers of each circular interlocking pile. The distance between the positioning plate 9 and the center of the circle is the radius of the circle enclosed by the center points of the interlocking piles. The positioning line 21 on the positioning plate 9 is adjusted to intersect with the laser line, and the positioning plate 9 is adjusted to be horizontal. The intersection of the plug rod 10 and the ground is the center point of the interlocking pile.
[0041] In this embodiment, the support platform 1 and the adjusting plate 4 are installed at the center of the circle formed by the center point of the interlocking piles by the fixing rod 3. After the adjusting plate 4 is adjusted to be parallel to the horizontal plane, a laser beam is emitted by the laser rangefinder. The orientation disk 201 is rotated so that the reference line 17 intersects the zero mark line 702 on the scale line 702. The positioning plate 9 is used to block the laser beam. The positioning line 21 on the positioning plate 9 is adjusted to intersect with the laser beam. The positioning plate 9 is moved along the direction of the laser beam. The orientation of the interlocking pile relative to the fixing rod 3 (the center of the circle formed by the center of the interlocking piles) is determined according to the direction of the laser beam. The distance from the center of the interlocking pile to the fixing rod 3 is determined by the positioning plate 9 and the laser rangefinder. The insertion rod 10 is vertically inserted into the ground. The position of the insertion rod 10 is the center point of the interlocking pile (i.e., the center point of the first group of interlocking piles).
[0042] When positioning adjacent interlocking posts, the center point of the already determined interlocking post is used as the base point (such as the center point of the first group of interlocking posts). The laser line intersecting the base point is used as the baseline (the laser ray parallel to the zero scale line 702). The included angle α between the center point of the interlocking post to be positioned and the base point is determined in the design document according to the number and diameter of the circular interlocking posts. With the base point position determined, the laser ray intersecting the base point is adjusted. By rotating the orientation component 2 and referring to the angle on the scale line 702, the included angle β between the adjusted laser ray and the baseline is made equal to the included angle α. The positioning plate 9 is then used to intersect the laser ray again to position the center point of the next group of interlocking posts.
[0043] 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.
