[0020] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "back" and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0023] The inventors discovered that bridge piers often use steel pipe piles as their primary load-bearing components. During trestle construction, accurately driving the steel pipe piles into the water as a support system is crucial, and strict control of the verticality of the steel pipe piles is crucial. Excessive verticality deviations will directly affect the stability and load-bearing capacity of the trestle's overall structure and may even pose safety hazards. Therefore, the verticality of the steel pipe piles significantly impacts the overall quality of the structure. However, in actual construction, poor verticality control of the steel pipe piles can significantly impact both construction quality and safety.

[0024] In order to solve the above problems, the inventors have proposed a positioning device, a construction device and a construction method for steel pipe piles of a trestle after research and development, which can effectively ensure that the verticality of the steel pipe piles meets the requirements, thereby ensuring the construction quality.

[0025] Example 1 See Figure 1 This embodiment proposes a positioning device for steel pipe piles of a trestle bridge. The positioning device realizes the positioning of the steel pipe piles 3 by the cooperation of the upper guide device 1 and the lower guide device 2. The upper guide device 1 includes a reserved connecting plate 11 and a guide frame 12. The reserved connecting plate 11 is provided on the trestle bridge 4. The guide frame 12 is detachably connected to the reserved connecting plate 11. Figure 1 In FIG. A, the guide frame 12 is provided with a first guide hole 121 for the steel pipe pile 3 to pass through. The lower guide device 2 is detachably connected to the barge 5. In another embodiment, the lower guide device 2 is detachably connected to the adjacent completed steel pipe pile 6. Figure 1 The example provided is that the lower guide device 2 is connected to the barge 5. Figure 1 In Figure B, the lower guide device 2 is provided with a second guide hole 21 for the steel pipe pile 3 to pass through. The first guide hole 121 and the second guide hole 21 are coaxially arranged. It is worth noting that the first guide hole 121 and the second guide hole 21 have the same cross-sectional shape as the steel pipe pile 3 and are slightly larger than the outer dimensions of the steel pipe pile 3.

[0026] The upper guide device 1 is connected to the pier 4 through a reserved connecting plate 11, which is convenient and quick to install, and the connection is firm and reliable. The first guide hole 121 of the guide frame 12 provides an upper guide path for the steel pipe pile 3, and the second guide hole 21 of the lower guide device 2 is the positioning reference below the steel pipe pile 3. When constructing the steel pipe pile 3, the steel pipe pile 3 is passed through the first guide hole 121 and the second guide hole 21 in sequence. Since the first guide hole 121 and the second guide hole 21 are coaxially arranged, precise guidance and limitation are formed at the upper and lower ends of the steel pipe pile 3, ensuring that the steel pipe pile 3 can always maintain a predetermined vertical direction during the process of inserting into the covering layer of the water body, effectively preventing the steel pipe pile 3 from tilting, thereby ensuring the positioning accuracy and verticality of the steel pipe pile 3, ensuring the stability and reliability of the foundation structure of the pier 4, and providing a strong guarantee for the quality of the entire pier 4 project.

[0027] Furthermore, the guide frame 12 is connected to the trestle 4 via a reserved connecting plate 11, providing a reliable and stable connection point for the guide frame 12. When the lower guide device 2 is detachably connected to the barge 5, the barge 5 can be secured in position using an anchor (not shown), providing a stable connection point for the lower guide device 2. Similarly, when the lower guide device 2 is detachably connected to the adjacent completed steel pipe pile 6, the completed steel pipe pile 6 also provides a stable connection point for the lower guide device 2. Therefore, the guide frame 12 and the lower guide device 2 provide stable support and guidance for the steel pipe pile 3, reducing the impact of external factors (such as water flow and wind) on the installation of the steel pipe pile 3 and enhancing the stability and reliability of the construction.

[0028] The positioning device of this embodiment provides a clear guide path for the installation of the steel pipe pile 3. The construction personnel only need to pass the steel pipe pile 3 through the first guide hole 121 and the second guide hole 21 in sequence, without the need for complicated measurement and correction work. This reduces the difficulty of construction operations and the dependence on the technical level of the construction personnel, improves construction efficiency, shortens the construction period, and also reduces the risk of construction accidents and rework caused by improper operation.

[0029] In one embodiment, see Figure 1 and Figure 2 The positioning device of this embodiment also includes a laser centering device (not shown in the figure) and a controller (not shown in the figure) provided on the pier 4. The lower guide device 2 includes a clamping assembly 22 and a telescopic rod 23. One end of the telescopic rod 23 is detachably connected to the barge 5. Figure 2 An example of the connection between the telescopic rod 23 and the barge 5 is given. In another embodiment, one end of the telescopic rod 23 is detachably connected to the adjacent completed steel pipe pile 6. The other end of the telescopic rod 23 is connected to the clamping assembly 22, and the clamping assembly 22 is provided with a second guide hole 21. The laser centering instrument is used to measure the deviation between the central axis of the first guide hole 121 and the central axis of the second guide hole 21, and transmit the data to the controller. The controller is connected to the telescopic rod 23 signal and is used to dynamically adjust the stroke of the telescopic rod 23 according to the deviation. The telescopic rod 23 drives the clamping assembly 22 to move, thereby changing the position of the second guide hole 21 until the deviation reaches the preset requirement (for example, the preset requirement can be set to a deviation of 0), thereby ensuring that the steel pipe pile 3 can be accurately inserted along the correct vertical direction, achieving high-precision positioning and verticality assurance.

[0030] The coordinated action of the laser plummet, controller, and telescopic rod 23 allows for real-time monitoring of the deviation between the first and second guide holes 121, 21, and precise adjustments to ensure their coaxial arrangement. This significantly improves positioning accuracy, effectively avoiding the significant positioning deviations that can occur with traditional purely manual or simple mechanical guidance methods, and enhancing the structural stability and safety of the trestle 4. Furthermore, the positioning process is automated and intelligent, minimizing manual intervention and reducing measurement and adjustment errors caused by human factors. This improves construction efficiency and quality stability. Furthermore, the automated adjustment process improves construction efficiency, shortens construction time, reduces costs such as equipment rental and labor, and enhances the economic benefits of the entire trestle project.

[0031] In one embodiment, see Figure 1 and Figure 2 The clamping assembly 22 includes a first clamping member 221, a second clamping member 222 and a connecting member 223. The first clamping member 221 is connected to the other end of the telescopic rod 23. Figure 2 In the example shown in which the first clamping member 221 is connected to the telescopic rod 23, in another embodiment, the second clamping member 222 is connected to the other end of the telescopic rod 23. The first end of the first clamping member 221 and the first end of the second clamping member 222 are rotatably connected, and the second end of the first clamping member 221 and the second end of the second clamping member 222 can be connected via a connecting member 223, and a second guide hole 21 is formed between the first clamping member 221 and the second clamping member 222.

[0032] When installing or removing the steel pipe pile 3, the connector 223 is first loosened, and the entire clamping assembly 22 is opened, allowing the steel pipe pile 3 to smoothly enter the guide position. Once the steel pipe pile 3 is in place, the second ends of the first clamping member 221 and the second clamping member 222 are tightly connected via the connector 223, accurately limiting the lateral movement of the steel pipe pile 3, ensuring that the steel pipe pile 3 remains stable during installation or use, and ensuring the verticality and installation accuracy of the steel pipe pile 3, which is conducive to improving the quality and stability of the entire trestle 4 structure.

[0033] The pivoting connection between the first and second clamping members 221, 222, and the design of the connector 223 make the opening and closing of the clamping assembly 22 extremely simple. Construction workers can quickly and easily open and close the second guide hole 21, facilitating the installation and removal of the steel pipe pile 3. This significantly shortens construction time and improves efficiency. Furthermore, if the clamping assembly 22 malfunctions or requires maintenance, construction workers can quickly locate the problem and perform repairs or replace parts. This reduces equipment downtime, ensures construction continuity, and improves efficiency.

[0034] In one embodiment, see Figure 1The upper guide device 1 further includes a guide portion 13 disposed at the lower end of the guide frame 12. As the steel pipe pile 3 passes through the first guide hole 121 and is lowered, the guide portion 13 first contacts the steel pipe pile 3, providing preliminary guidance for the steel pipe pile 3, enabling the pile 3 to more accurately move toward the second guide hole 21. This provides better prerequisites for the coaxial fit between the first guide hole 121 and the second guide hole 21, thereby improving the positioning accuracy and verticality control effect of the entire positioning device on the steel pipe pile 3.

[0035] In one embodiment, see Figure 3 The guide frame 12 includes a locking buckle 122 and a fixing member 123 that are interconnected. The fixing member 123 is connected to the reserved connecting plate 11. The locking buckle 122 is provided with a first guide hole 121. When the steel pipe pile 3 is ready to be lowered, the locking buckle 122 is in an adjustable open state, which facilitates the smooth entry of the steel pipe pile 3 into the interior thereof. When the steel pipe pile 3 reaches the position of the locking buckle 122, the locking buckle 122 is closed by its own locking mechanism (such as bolt tightening, buckle engagement, etc.), and a first guide hole 121 is formed on the inner side of the locking buckle 122. The lateral displacement of the steel pipe pile 3 is limited by the first guide hole 121, thereby effectively preventing the steel pipe pile 3 from shaking or displacement during the subsequent lowering process, thereby improving the installation accuracy.

[0036] Example 2 Based on the same inventive concept, see Figure 4-Figure 6 This embodiment provides a construction device for steel pipe piles of a trestle, which at least includes a lifting device 7, a vibrating pile hammer 8, a drilling rig 9 and the positioning device for the steel pipe piles of the trestle in the first embodiment.

[0037] In a specific embodiment, the construction device of this embodiment also includes a porous seepage pressure monitoring tube, an alarm and a control terminal. The porous seepage pressure monitoring tube is arranged along the circumference of the steel pipe pile 3, and is used to monitor the seepage pressure value of the soil layer around the pile in real time. The alarm and the control terminal are both arranged on the trestle 4, and the control terminal is connected to the porous seepage pressure monitoring tube and the alarm signal. The control terminal is used to receive the seepage pressure value of the soil layer around the pile transmitted by the porous seepage pressure monitoring tube, and to determine whether the seepage pressure value of the soil layer around the pile exceeds a preset safety threshold. If so, the alarm is activated. After receiving the activation signal, the alarm will sound an alarm in a specific manner, such as emitting a loud alarm sound, flashing a warning light, etc., to attract the attention of the construction personnel.

[0038] As the steel pipe pile 3 passes through the water, its ends and sides primarily interact with the overburden of the riverbed or seabed. This overburden is the target of seepage pressure monitoring. Tides and waves in open waters can cause dynamic fluctuations in water pressure. A porous seepage pressure monitoring tube is used to distinguish between ambient water pressure fluctuations and actual leakage signals. Combined with an alarm and control terminal, a timely warning can be issued if the seepage pressure of the soil layer surrounding the pile exceeds a preset safety threshold, indicating leakage. This allows construction personnel to take timely remedial measures, minimize safety risks, and ensure the safety of construction personnel and the smooth progress of the project.

[0039] In a specific embodiment, the construction device of this embodiment also includes a pumping device, a slurry storage device and a grouting pipe. The slurry storage device is provided on the trestle 4 and is connected to the pumping device. The slurry storage device is used to store the plugging slurry. The construction personnel prepare the plugging slurry in advance based on the amount and proportion of various raw materials (such as cement, water glass, additives, etc.) to obtain the plugging slurry that meets the design requirements to meet the plugging needs of the leakage situation. The grouting pipe is connected to the steel pipe pile 3 and the slurry storage device respectively, forming a complete channel for the plugging slurry from the slurry storage device to the steel pipe pile 3. Under the pressure of the pumping device, the plugging slurry is accurately injected into the leakage area through the grouting pipe, forming a continuous and dense plugging barrier, which fundamentally solves the leakage problem and reduces the impact of leakage on the project progress and quality.

[0040] Example 3 Based on the same inventive concept, see Figure 8 This embodiment proposes a construction method for steel pipe piles of a trestle, which specifically includes the following steps: Step S101, refer to Figure 1 , connect the guide frame 12 to the reserved connecting plate 11, and connect the lower guide device 2 to the barge 5 or the adjacent completed steel pipe pile 6; Step S102: Refer to Figure 4 , using the lifting device 7 to lift the steel pipe pile 3 through the first guide hole and the second guide hole in sequence until the steel pipe pile 3 contacts the cover layer in the water body in the construction area; Step S103, refer to Figure 5 , using a vibrating pile hammer 8 to drive the steel pipe pile 3 until the pile tip elevation and penetration meet the preset construction requirements; Step S104, refer to Figure 6 , using the drilling rig 9 to drill a hole in the steel pipe pile 3 until the construction hole in the steel pipe pile 3 meets the design elevation; In the above step S104, refer to Figure 5 and Figure 6During the process of drilling a hole in the steel pipe pile 3 using the drilling rig 9, leakage may occur, and it is necessary to use a porous seepage pressure monitoring tube, a control terminal, and an alarm for real-time monitoring. A porous seepage pressure monitoring tube can be provided around the circumference of the steel pipe pile 3, and the control terminal and the alarm can be provided on the trestle 4. The mechanism of action of the porous seepage pressure monitoring tube, the control terminal, and the alarm is consistent with that of the second embodiment and will not be repeated here. The specific process of drilling a hole in the steel pipe pile 3 using the drilling rig 9 until the construction hole in the steel pipe pile 3 meets the design elevation can include the following steps: Step S1041: During the drilling process of the steel pipe pile 3 by the drilling rig 9, the seepage pressure value of the soil layer around the pile is monitored in real time by the porous seepage pressure monitoring tube. The seepage pressure value of the soil layer around the pile transmitted by the porous seepage pressure monitoring tube is received by the control terminal, and it is determined whether the seepage pressure value of the soil layer around the pile exceeds a preset safety threshold. If so, an alarm is activated and the drilling operation of the drilling rig 9 is stopped. Step S1042: Use the vibrating pile hammer 8 to impact and sink the steel pipe pile 3 in sections until the seepage pressure value of the soil layer around the pile reaches a preset safety threshold; In the above step S1042, when a pumping device, a slurry storage device and a grouting pipe are used, while the steel pipe pile 3 is sunk in sections by using the vibrating pile hammer 8, the grouting pipe can be used to inject plugging slurry into the steel pipe pile 3 to form a continuous and dense plugging barrier in the leakage area, further solving the leakage problem.

[0041] Step S1043, restart the drilling operation of the drilling rig 9, and execute the above-mentioned process of real-time monitoring of the seepage pressure value of the soil layer around the pile by the porous seepage pressure monitoring tube and judgment by the control terminal until the construction hole in the steel pipe pile 3 meets the design elevation.

[0042] Step S105, refer to Figure 7 , install the steel cage in the construction hole and pour concrete.

[0043] After completing the above step S105, when the concrete is ready to set, the guide frame and the lower guide device are removed, and the upper structure of the trestle is constructed. Figure 8 The trestle shown repeats the above steps S101 to S105 for the next steel pipe pile to be constructed.
