Description

Technical Field

[0001] This application relates to the field of reverse construction technology, and in particular to a vertical adjustment control system for integrated pile and column construction in reverse construction. Background Technology

[0002] The reverse construction method is an advanced construction technology for high-rise buildings and underground engineering. It involves constructing the underground structure layer by layer from top to bottom while simultaneously advancing above-ground construction, thus shortening the construction period, optimizing resources, and preventing subsidence of the surrounding foundation. In existing technologies, the vertical load-bearing system of the main structure in reverse construction often adopts a "pile-column integrated" structure. This involves constructing cast-in-place piles within the foundation pit. After the piles are poured to the bottom elevation of the pit, a permanent structural column, such as a steel pipe column, is installed on top of the piles to support the upper construction load. In this reverse construction method, the steel pipe column is typically nested within large-diameter cast-in-place piles. Its verticality, azimuth, and the accuracy of its alignment with the pile center directly affect the structural stability and the accuracy of subsequent structural connections.

[0003] Currently, the full-rotation construction device for integrated pile and column construction using the reverse construction method typically includes a positioning platform (also known as a universal platform, positioning balance plate, etc.) and a full-rotation drilling rig. The positioning platform and the hydraulic legs of the full-rotation drilling rig can be aligned using a limiting arc plate and a limiting motor, thus ensuring that the steel pipe column does not deviate, tilt, or center off during insertion. However, this method requires manually adjusting the position of the limiting arc plate by driving the limiting motor, which is cumbersome and inefficient. Furthermore, the subjective operation of the workers has a significant impact, and the accuracy of vertical adjustment is uncontrollable. Utility Model Content

By setting a positioning ring including a circular groove on the positioning platform, the oil legs of the full-rotation drilling rig can be directly placed in the circular groove of the positioning ring, thereby achieving alignment between the positioning platform and the full-rotation drilling rig. This ensures that no deviation, tilting, or centering error occurs during the insertion of the steel pipe column, and that the alignment efficiency is high, the plumbness adjustment accuracy is controllable, and no subjective operation is required from the operators.

[0030] The illustrative embodiments of this application include, but are not limited to, a plumb control system and plumb control equipment for integrated pile-column construction in reverse construction.

[0031] As mentioned in the background section, the current process of aligning the positioning platform with the hydraulic legs of the full-rotation drilling rig using limit arc plates and limit motors is cumbersome, inefficient, and heavily influenced by operator subjectivity, resulting in uncontrollable vertical adjustment accuracy. To address these issues, this application proposes a vertical adjustment control system for integrated pile-column construction in the reverse-construction method. By setting a positioning ring with a circular groove on the positioning platform, the hydraulic legs of the full-rotation drilling rig can be directly positioned within the circular groove of the positioning ring, thereby achieving alignment between the positioning platform and the full-rotation drilling rig. This ensures that misalignment, tilting, and centering deviations are prevented during the insertion of the steel pipe column, while also providing high alignment efficiency, controllable vertical adjustment accuracy, and eliminating the need for operator subjectivity.

[0032] The following is in conjunction with the appendix Figures 1 to 5 This application describes the vertical adjustment control system.

[0033] Figure 1 A schematic diagram of a vertical adjustment control system provided in an embodiment of this application is shown. Figure 1 As shown, the vertical adjustment control system includes a positioning platform 1, a full-rotation drilling rig 2, a casing 3, a steel pipe column 4, multiple total stations 5, multiple plumb lines 6, and an inclinometer 7.

[0034] Among them, the casing 3 is set at the injection hole (not in Figure 1 As shown in the diagram, the casing 3 can be a steel cylinder embedded in the pile location of the grouting hole, serving as a "guide and protective sleeve" for drilling. The center point of the casing 3 represents the center of the pile location, acting as the "starting point" and "reference" for drilling, providing a precise drilling position for subsequent drilling rigs. In the initial stage of drilling, the casing 3 guides the drill bit of the drilling rig to drill vertically downwards, preventing the drill bit from deviating from its designed position due to uneven soil hardness, which is crucial for ensuring the verticality of the pile. In addition, the casing 3 can also prevent the borehole opening from collapsing and prevent surface water or debris from falling in. In the embodiments of this application, the casing 3 can be selected as a high-strength, waterproof, and reusable steel casing.

[0035] refer to Figure 1 The positioning platform 1 is positioned above the casing 3. Figure 2 A schematic diagram of a positioning platform provided in an embodiment of this application is shown. Figure 2 As shown, the positioning platform 1 has N positioning rings 11 on its surface away from the protective casing 3. Each of the N positioning rings 11 is composed of an arc plate, and each positioning ring 11 includes a circular groove 12 enclosed by the arc plate. Here, N is a positive integer greater than 1, such as... Figure 2 The N shown can be 4. In other embodiments of this application, N can also be other values, such as 2, 3, 5, 8, etc. For ease of description, the accompanying drawings of this application use N of 4 as an example. In addition, the positioning platform 1 includes a first circular hole 13, which allows the steel pipe column 4 to pass through the positioning platform 1 and be drilled into the grouting hole or into the casing 3 by the full-rotation drilling rig 2.

[0036] Continue to refer to Figure 1 The full-rotation drilling rig 2 is set on the positioning platform 1. Figures 3A to 3E A schematic diagram of a full-rotation drilling rig provided in an embodiment of this application is shown. Wherein, Figure 3A A three-dimensional schematic diagram of the entire rotary drilling rig 2 is shown. (See attached diagram.) Figure 3A As shown, the full-rotation drilling rig 2 includes a second circular hole 21, a third circular hole 22, N hydraulic legs 23 (also known as hydraulic cylinder legs), a full-rotation clamping device 24, and a fine-tuning hydraulic cylinder 25. The second circular hole 21 and the third circular hole 22 of the full-rotation drilling rig 2 allow the steel pipe column 4 to pass through the full-rotation drilling rig 2 and be drilled into the grouting hole or into the casing 3.

[0037] N hydraulic legs 23 provide stable support for the full-rotation drilling rig 2, preventing the equipment from tipping over, sinking, or moving during operation. Each hydraulic leg 23 can be powered by a hydraulic cylinder (not in...). Figure 3A It consists of a hydraulic rig (shown in the diagram) and a support foot plate. Operators can inject high-pressure hydraulic oil into the hydraulic cylinders by manipulating the hydraulic valves, which in turn pushes the piston rod outwards, lifting the entire equipment off the ground. Afterwards, by controlling the extension length of each hydraulic leg 23, the full-rotation drilling rig 2 can be adjusted to a level position, ensuring stability even on uneven ground.

[0038] Figure 3B It shows Figure 3A A diagram illustrating the first direction corresponding to the viewing angle (frontal view). For example... Figure 3BAs shown, when lifting the full-rotation drilling rig 2 off the ground, each oil leg 23 includes a support foot plate 231. The support foot plate 231 can be a load-bearing plate at the end of the oil leg 23, distributing the huge pressure of the oil leg 23 to a larger ground area and preventing the equipment from sinking or overturning. Figure 3C It shows Figure 3A The diagram illustrates the second direction corresponding to the viewpoint (looking up). For example... Figure 3C As shown, the number of support feet 231 is also N (which can be the same as...). Figure 3A and Figure 2 The same N=4), and the positions of these N support plates 231 are the same as Figure 2 The N positioning rings 11 shown correspond one-to-one.

[0039] The correspondence is as follows: when the vertical alignment of the full-rotation drilling rig 2 and the positioning platform 1 is achieved (e.g., the first circular hole 13, the second circular hole 21, and the third circular hole 22 are coaxially arranged and their centers are vertically aligned), each of the N support feet 231 is positioned in the circular groove 12 of the corresponding positioning ring 11. In other words, in the embodiments of this application, the N oil legs 23 and... Figure 2 The N positioning rings 11 shown correspond one-to-one. Each of the N oil legs 23 is disposed in the circular groove 12 of the corresponding positioning ring 11, so that the center of the first circular hole 13 of the positioning platform 1 is vertically aligned with the center of the second circular hole 21 and / or the third circular hole 22 of the full-rotation drilling rig. The shape and size of the support foot plate 231 can be the same as the shape and size of the corresponding circular groove 12, so that the support foot plate 231 can be placed precisely in the corresponding circular groove 12.

[0040] Furthermore, by placing the support foot plate 231 into the corresponding circular groove 12, such that when... Figure 3A When the full-rotation drilling rig 2 shown is set on the positioning platform 1, the positional relationship between the full-rotation drilling rig 2 and the positioning platform 1 is coaxial, and the centers of the circular holes are rotated opposite each other. This prevents misalignment, tilting, and centering deviation during the insertion of the steel pipe column. In addition, operators can directly align the support foot plate 231 and the circular groove 12 without adjusting the limit structure using the limit motor in existing technology. This minimizes the impact of subjective operation and ensures controllable vertical adjustment accuracy.

[0041] Figure 3D It shows Figure 3A A diagram illustrating the third-party corresponding viewpoint (left-hand viewpoint). For example... Figure 3DAs shown in the embodiments of this application, the full-rotation drilling rig 2 may further include a fine-tuning cylinder 25, which can cooperate with the full-rotation clamping device 24 to clamp the steel pipe column 4, thereby realizing real-time adjustment of the verticality of the steel pipe column 4. For example, the fine-tuning cylinder 25 can be selected as a hydraulic cylinder with a short stroke but very high control precision. By receiving instructions from the control system, the fine-tuning cylinder 25 can perform extension and retraction at the millimeter level or even smaller units. In the embodiments of this application, two or more fine-tuning cylinders 25 can be arranged on one side of the full-rotation drilling rig 2. By coordinating the extension and retraction of the fine-tuning cylinders 25, a micro-thrust in the desired direction can be generated.

[0042] Figure 3E It shows Figure 3A The diagram illustrates the fourth direction corresponding to the viewpoint (looking up). For example... Figure 3D As shown, the fully rotating clamping device 24, serving as a clamping and transmission component, is disposed on the wall of the second circular hole 21 and is used to clamp the steel pipe column 4. For example, the fully rotating clamping device 24 firmly clamps the steel pipe column 4 by hydraulic or mechanical means and can rotate freely within a 360° range, thereby enabling the steel pipe column 4 to be corrected in any horizontal direction.

[0043] Furthermore, the verticality of the steel pipe column 4 can be adjusted in real time through the full-rotation clamping device 24 and the fine-tuning cylinder 25. The adjustment process is fast and automated, significantly shortening the calibration time and improving installation efficiency. In addition, all adjustment processes are carried out smoothly under system control, avoiding the uncertainty and high risk of manual operation.

[0044] Optionally, in order to further achieve the center alignment of the positioning platform and the casing, in the embodiments of this application, Figure 4 This diagram illustrates a positioning platform and casing vertical adjustment method provided in an embodiment of this application. Figure 4 As shown, the casing 3 has a first crosshair 31 at the opening of the injection hole near the ground. The intersection of the first crosshair 31 is the center point or center of the injection hole or casing. The positioning platform 1 has a second crosshair 14 at the first circular hole 13. The intersection of the second crosshair 14 is the center point or center of the first circular hole 13. Then, as... Figure 4 As shown, the positioning platform 1 also includes a first vertical line 15 and a first gravity block 16. The intersection of the first gravity block 16 and the second crosshair 14 is connected by the first vertical line 15. The first gravity block 16 ensures that the first vertical line 15 is vertically aligned, or hangs downwards in a vertical direction. Therefore, when the first vertical line 15 contacts the intersection of the first crosshair 31, the center point of the first circular hole 13 and the center point of the casing 3 are vertically aligned. Thus, the casing 3, the positioning platform 1, and the full-rotation drilling rig 2 are all aligned, ensuring that the center of the steel pipe column will not shift during insertion.

[0045] Optionally, in embodiments of this application, the three-line convergence method can be used to locate, for example... Figure 4 The center point of the injection hole shown (i.e., the intersection of the first crosshair 31). Figure 5 A schematic diagram of a wire-laying frame system provided in an embodiment of this application is shown. The wire-laying frame system is positioned above the casing 3 and is used to determine the position of the first crosshair 31. For example, the wire-laying frame system may include a layout frame 8, which can determine the center coordinate point of the grouting hole using a prism rod, and then draw out the pile axis. Specifically, the layout frame 8 may include a wire-laying hole, through which a second plumb line 81 and a second gravity block 82 are suspended downwards. When the center of the wire-laying hole, the prism center of the prism rod, and the center coordinate point of the grouting hole coincide on a straight line, the first crosshair 31 is drawn out, where the intersection of the second plumb line 81 and the first crosshair 31 is in contact. At this time, the intersection of the first crosshair 31 is the center of the grouting hole, and this intersection can be further used to determine, for example, the center of the grouting hole. Figure 4 The alignment of the protective casing 3 and the positioning platform 1 is shown.

[0046] In some embodiments of this application, Figure 5 The wire-laying frame system shown can use a positioning device to assist in positioning the layout frame 8 and placing the prism rod of the layout frame 8. For example, the positioning device can be a small tool ladder, which can be a steel structure and is in the form of a straight ladder. Specifically, the small tool ladder can consist of two side ladders and several crossbars connecting the side ladders, and a support crossbar connecting the side ladders is provided in the middle of the small tool ladder. In this way, when the small tool ladder is placed horizontally on the pouring hole, the support crossbar can be used to place the prism rod of the layout frame 8, so that the wire-laying frame system can be stably set above the pouring hole.

[0047] also, Figure 1 The multiple total stations 5 shown can measure the verticality of the steel pipe column 4 clamped by the full-rotation drilling rig 2 from two orthogonal directions, X and Y. For example, as Figure 1As shown, the total station 5 is used to transmit or receive optical signals. By attaching a reflecting prism (or using a special target plate) to the top and middle sections of the steel pipe column on the same side, it can simultaneously measure the horizontal angle, vertical angle, and slope distance. The internal microprocessor immediately calculates and displays the three-dimensional coordinates (X, Y, Z) or relative position of the points. Then, by aiming at the measurement points at the top and middle sections, the total station measures the three-dimensional coordinates (X1, Y1, Z1) of the measurement points in the middle section and the three-dimensional coordinates (X2, Y2, Z2) of the measurement points at the top, thereby obtaining the X-direction deviation ΔX = X2 - X1, the Y-direction deviation ΔY = Y2 - Y1, and the height difference ΔH = Z2 - Z1 (i.e., the height of the steel pipe column segment or the height difference between measurement points). Finally, the verticality in the X direction is calculated as ΔX / ΔH, and the verticality in the Y direction is calculated as ΔY / ΔH. Therefore, the total station 5 can accurately and quickly measure the horizontal deviation of the top of the steel pipe column relative to the middle section or the design baseline.

[0048] The inclinometer 7 measures the tilt angle of the steel pipe column 4 relative to the direction of gravity using a tilt sensor. This tilt sensor can be positioned on the steel pipe column 4, such as at its top (because the displacement and tilt angle are greatest at the top, thus providing the highest sensitivity and resolution). For example, the tilt sensor can be a microelectromechanical system accelerometer or an electrolyte sensor, calculating the tilt angle by sensing the change in the component of the Earth's gravitational acceleration along its sensitive axis. When the tilt sensor tilts along with the steel pipe column 4, gravity produces a component along its measuring axis. The tilt sensor measures this component and calculates the angle between itself and the vertical line of gravity using the arcsine or arctangent formulas.

[0049] Furthermore, this application can also include a feedback device that adjusts the positioning platform 1 and the full-rotation drilling rig 2 based on data collected by the total station 5 and the tilt sensor, ensuring that the center of the steel pipe column 4 coincides with the center of the positioning platform 1 and the full-rotation drilling rig 2. For example, this feedback device can be connected to the total station 5 and the inclinometer 7 via a data connection cable, and the feedback device includes a monitor. By connecting the data connection cable on the steel pipe column 4 to the monitor, during the insertion of the steel pipe column, the sensing probes of the total station 5 and the inclinometer 7 collect real-time data on the verticality changes of the steel pipe column 4. The monitor automatically calculates the changes and instrument readings. When the reading changes significantly, fine-tuning is performed by adjusting the hydraulic jacks of the positioning platform 1 and the full-rotation drilling rig 2 to bring the readings closer to zero until the steel pipe column 4 is inserted to the design elevation. Furthermore, through multi-device linkage, the center point deviation control, verticality correction, and real-time elevation reading of the steel pipe column 4 during the insertion process can be achieved.

[0050] In the vertical adjustment control system provided in this application, the positioning platform 1 and the full-rotation drilling rig 2 can be aligned by the cooperation of the support foot plate 231 and the circular groove 12 of the positioning ring 11. The positioning platform 1 and the casing 3 can be aligned by... Figure 4 and Figure 5 The vertical adjustment method shown achieves alignment, and the verticality of the steel pipe column 4 can be monitored and corrected in real time using a total station 5 and an inclinometer 7. This achieves the vertical adjustment goals of center coincidence, precise verticality, consistent elevation, and controllable orientation of the steel pipe column, ensuring construction accuracy and project quality.

[0051] The working process of the sag control system shown in this application will be described below.

[0052] Specifically, firstly, it can be done through Figure 5 The shown wire-laying frame system is configured with the first crosshair alignment 31. Specifically, the wire-laying frame 8 is placed at the center of the casing 3, and the prism rod is placed at the center hole of the wire-laying frame 8. Simultaneously, the wire-laying frame 8 is extended downwards with a second plumb line 81 and a second gravity block 82. Using a total station, the wire-laying frame 8 is moved to align the prism center, the wire-laying hole center, and the column center. Then, two crosshairs are drawn through the second plumb line 81, forming the first crosshair alignment 31. The intersection of these first crosshairs 31 is the center of the grouting hole. In some embodiments of this application, the operator can place the wire-laying frame 8 on a small, horizontally positioned ladder above the grouting hole. This small ladder has a supporting crossbeam connecting the ladder sides in the middle, which can be used to place the prism rod of the wire-laying frame 8, allowing the wire-laying frame system to be stably positioned above the grouting hole.

[0053] Next, the intersection of the first vertical line 15 and the first gravity block 16 of the positioning platform 1 with the first crosshair 31 is aligned, thereby aligning the center of the positioning platform 1 with the center of the injection hole. Then, the full-rotation drilling rig 2 is placed on the positioning platform 1, and during this process, the support plates 231 of the four oil legs 23 of the full-rotation drilling rig 2 are engaged with the circular grooves 12 of the positioning ring 11 of the positioning platform 1, so that the center of the positioning platform 1 and the center of the full-rotation drilling rig 2 coincide. Furthermore, after the steel pipe column 4 is clamped by the full-rotation clamping device 24, since the center of the steel pipe column 4 and the center of the full-rotation drilling rig 2 are concentric, when the center of the full-rotation drilling rig 2 is aligned with the center of the positioning platform 1 and the center of the injection hole, the center of the steel pipe column 4 is also aligned with the center of the injection hole, thus ensuring that the center of the steel pipe column does not shift.

[0054] Finally, the total station 5 performs real-time measurement on the steel pipe column from two orthogonal directions X and Y respectively, and an inclination sensor is arranged on the steel pipe column 4, so that the inclination degree of the steel pipe column 4 is measured by the inclinometer 7, and the data can be synchronously transmitted to a display terminal. Furthermore, through multi-device linkage, center point deviation control, verticality correction and real-time elevation reading of the steel pipe column 4 during the inserting process are realized.

[0055] Finally, through this verticality adjustment process, three-dimensional closed-loop control for verticality adjustment of the steel pipe column is realized, avoiding the traditional "centering-verticality adjustment-deviation" cycle. Moreover, the center point deviation is ≤5mm, the verticality is controlled within 1 / 300, and the elevation error is ≤10mm; the equipment has high universality, and is suitable for pile foundations with a diameter ranging from 1.2m to 2.0m and steel pipe columns with different diameters; a large amount of hardened platforms and complex supports are not required, and the device can be positioned after the platform is centered; a "standardized verticality adjustment operation procedure" is formed, which is convenient for promotion and training; construction problems such as structural eccentricity and difficult connection are avoided, and the overall structural stability is guaranteed.
