Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical foundation engineering, and more specifically, to a pile foundation pipe pile core rapid high-precision positioning device and positioning method. Background Art

[0002] In modern infrastructure projects, pipe pile construction is widely used in bridges, buildings, subways and other projects, and is favored for its strong bearing capacity and fast construction speed. Pipe piles are a type of precast concrete pile with excellent compression and pull-out resistance, suitable for a variety of soil conditions. With the acceleration of urbanization, buildings have increasingly stringent requirements for infrastructure, which requires pipe pile construction to improve construction efficiency while ensuring structural safety.

[0003] In pipe pile construction, pile center positioning is a key link to ensure the quality and safety of pile foundation construction. The accurate pile center position directly affects the stability and durability of subsequent construction, so the accuracy and efficiency of positioning are crucial. In the prior art, pile center positioning mainly relies on manual measurement methods, usually using simple measuring instruments such as levels and steel rulers. These traditional methods are greatly affected by environmental factors, such as wind speed, light changes, and uneven ground, resulting in low measurement accuracy and prone to errors. In some complex construction environments, these errors may have a serious impact on the construction quality of the pile foundation; in addition, manual measurement is often time-consuming and labor-intensive, and workers need to perform multiple measurements to confirm the position of the pile center, which is particularly unsuitable for construction sites where time is tight. Especially in construction environments that require rapid response, traditional measurement methods are extremely inefficient.

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the described embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] like Figure 1-5 As shown, this embodiment discloses a pile foundation pipe pile center rapid high-precision positioning device and positioning method, including a positioning component 1 and a fixing unit 2, the positioning component 1 is provided with a connecting portion 3 connected to the fixing unit 2; the positioning component 1 is provided with a measuring unit 4, and the measuring unit 4 is provided with a plurality of distance measuring sensors 401.

[0045] The fixing unit 2 includes a surrounding clamp 201, which is used to fix the device on the circumference of the pipe pile to be measured. Locking pieces 202 are evenly arranged on the outer circle of the surrounding clamp 201. The surrounding clamp 201 can firmly fix the device on the circumference of the pipe pile to be measured, and cooperate with the locking piece 202 to ensure that no displacement occurs during the measurement process, thereby improving the stability of the device. In the specific implementation process, the locking piece 202 can be set as a locking screw or a compression spring lock buckle.

[0046] The surrounding hoop 201 is provided with a telescopic mechanism for adjusting the length. The telescopic mechanism can adjust the length of the surrounding hoop 201 to adapt to pipe piles of different diameters. In practical applications, the diameters of the pipe piles to be measured may vary. The telescopic mechanism can ensure that the surrounding hoop 201 fits closely to the outer circumference of the pipe pile to be measured by adjusting the length of the surrounding hoop 201, so that the positioning device is stably fixed on the pipe pile to be measured, avoiding sliding or loosening, and ensuring the measurement accuracy and stability during the positioning process.

[0047] The surrounding clamp 201 includes several clamp sections, each of which is provided with a telescopic mechanism; the telescopic mechanism includes a clamp slide groove arranged on the clamp section, and an extension section that cooperates with the clamp slide groove and can slide and telescope along the clamp slide groove; the clamp slide groove is provided with a plurality of evenly spaced through holes, which cooperate with the compression spring lock buckle arranged on the extension section to limit the position.

[0048] During the specific implementation process, the telescopic mechanism is provided with a clamp slide groove and an extension section, and the length of the extension section is adjusted by sliding the clamp slide groove, thereby changing the overall size of the surrounding clamp. This structure can flexibly adapt to different sizes of pipe piles to be tested, thereby improving the versatility and practicality of the equipment.

[0049] The connecting part 3 is a plurality of connecting rods 301, one end of the connecting rod 301 is connected to the bottom of the positioning assembly 1, and the other end is connected to the fixing unit 2. The connecting rod 301 is connected to the hoop section.

[0050] In the specific implementation process, the connecting rod 301 is connected to the hoop section through a hinge structure. One end of the connecting rod 301 is a spherical joint. A hemispherical groove is correspondingly provided on the hoop section. The spherical joint can rotate freely within a certain range after being inserted into the groove. The spherical joint is fixed in the groove by bolts or buckles, allowing the connecting rod to have a certain degree of rotation freedom. During installation, the appropriate angle is found by rotation adjustment, and then the position of the connecting rod 301 is fixed by the locking structure. The spherical hinge method can adjust the shape or installation position of different pipe piles to be tested by rotating a certain angle. Especially when the surface of the pipe pile is irregular, the angle adjustment of the spherical hinge can better fix the device on the outer cylindrical surface of the pipe pile to be tested to a certain extent.

[0051] The positioning assembly 1 is provided with a positioning plate 101, an electric telescopic rod 402 and an outer frame 102; the electric telescopic rod 402 is provided on at least three borders of the outer frame 102, and the telescopic end of the electric telescopic rod 402 on the outer frame acts on the positioning plate 101 through telescopic action, driving the movement of the positioning plate 101 to control the relative position of the positioning plate 101.

[0052] The distance measuring sensor 401 on the outer frame 102 is installed below the telescopic end of the electric telescopic rod 402 and is connected to the electric telescopic rod 402 .

[0053] The distance measuring sensor 401 is a laser distance measuring sensor, a photoelectric distance measuring sensor or an infrared distance measuring sensor.

[0054] A slide groove 1021 is provided in the middle of the frame of the electric telescopic rod 402, and a pulley 4021 is connected to the sliding end of the electric telescopic rod 402. The electric telescopic rod 402 is connected to the outer frame 102 through the pulley 4021 embedded in the slide groove 1021. The structural combination of the slide groove 1021 and the pulley 4021 is to provide stable guidance and support during the extension and retraction process of the electric telescopic rod 402, ensuring that the positioning plate 101 can accurately and smoothly adjust its position when moving.

[0055] During the specific implementation process, the sliding end of the electric telescopic rod 402 is provided with a snap device with a groove, and the central axis or both sides of the pulley 4021 are provided with a snap part, which can be inserted into the snap groove on the electric telescopic rod 402. When the pulley 4021 is fully inserted, the snap structure will automatically lock the pulley 4021 to prevent it from falling off.

[0056] The outer frame 102 is a triangular frame or a quadrilateral frame; when measuring a more regular pipe pile to be measured, the outer frame 102 can be set as an equilateral triangular frame or a square frame. The positioning plate 101 is circular, equilateral triangular or square.

[0057] The triangle has the characteristics of high structural stability, especially the regular triangle frame, in which the length of each side is equal, the overall force is uniform, and it is not easy to deform. Because the triangle has a compact structure, it is suitable for pipe piles with smaller diameters or higher regularity, which can effectively prevent the frame from twisting or deforming, and can maintain stable measurement in a complex force environment. The quadrilateral frame has a larger space and is suitable for fixing on pipe piles with larger pipe diameters. The quadrilateral structure provides a larger contact surface, which can reduce the shaking during measurement. In the selection of the positioning plate 101, the circular structure has better symmetry, and the force in all directions is evenly distributed. It is suitable for pipe piles of various shapes, especially irregular pipe piles or non-precisely circular pipe piles. There is no directional restriction when the whole rotates, which reduces the need to adjust the positioning direction, and the circular positioning plate is easier to align with the pile center when positioning the pile center; and the square positioning plate can provide more support points. In occasions where high measurement accuracy is required, especially in the measurement of large-diameter pipe piles, the square positioning plate has better support effect and is more stable.

[0058] The frame can be set as a telescopic rod, and the two ends of the frame are telescopic structures. By setting a telescopic frame, the positioning device can be adjusted according to the size of the pipe pile. The telescopic rod can be stretched or contracted as needed, so that the positioning device can adapt to pipe piles of different sizes without changing the equipment, which enhances the versatility of the equipment; the telescopic structure at both ends of the frame allows each corner of the frame to be adjusted independently according to specific needs, helping the equipment to better maintain balance, so that the positioning plate (or other measuring components) and the pipe pile to be measured are accurately aligned, thereby improving the accuracy of measurement and positioning.

[0059] A positioning hole 1011 is provided at the center of the positioning plate 101 for placing a positioning instrument. The measurement result is based on the center of the positioning hole 1011 being aligned with the center of the pipe pile to be measured and being on the same vertical line as the standard for accurate positioning. Example 2

[0060] like Figure 1-5 As shown, this embodiment discloses another pile foundation pipe pile center rapid high-precision positioning device, the difference is:

[0061] The outer frame 102 is provided with a device switch 1022, and the positioning plate 101 is provided with a host 1012 inside. The host 1012 is electrically connected to the device switch 1022, and the device switch 1022 controls the host 1012, thereby controlling the relative movement of the electric telescopic rod 402 and the positioning plate 101. The device switch 1022 is a multi-color indicator light for indicating the remaining power level of the device.

[0062] A protective cover is set on the fixing unit 2, and the connecting cover ears of the protective cover are welded to the surrounding clamp 201 on the fixing unit 2. The top of the protective cover is used to protect the positioning component 1 and is located above the positioning component 1. The design of the protective cover is conducive to protecting core components such as the ranging sensor 401 and the electric telescopic rod 402. The protective cover can effectively prevent dust, moisture and other external environments from affecting these components. Even when a thunderstorm occurs on the construction site, the electrical components of the device can be protected in time to extend their service life.

[0063] During the specific implementation process, during the preparation stage, the staff first presses the device switch 1022 and checks the color display of the multi-color indicator light of the device switch 1022. If the color displayed by the multi-color indicator light is green, it means that the remaining power of the device is greater than 80%; if the color displayed by the multi-color indicator light is yellow, it means that the remaining power of the device is between 30%-79% and can continue to be used; if the color displayed by the multi-color indicator light is red, it means that the remaining power of the device is less than 30%. At this time, the device should be charged, and wait for the multi-color indicator light to charge and turn green before using it; if the multi-color indicator light of the device switch 1022 has no color display, it means that the device power has been exhausted and needs to be charged until the multi-color indicator light turns green before use; if the device is normal, press the device switch 1022 again, turn off the instrument, and bring the device to the pipe piles at the construction site. The staff picked up the pile foundation pipe pile center rapid and high-precision positioning device and positioning method, slowly put the device's surrounding clamp 201 on the outer circumference of the pipe pile until the positioning plate 101 is slightly suspended on the top of the pipe pile, and then slightly tightened the locking piece 202 on the surrounding clamp 201, thus completing the preparations before field measurement. Example 3

[0064] like Figure 6-8 As shown, this embodiment discloses a positioning method for a pile foundation pipe pile center rapid high-precision positioning device, comprising the following steps:

[0065] S1: Bring the pile foundation pipe pile center rapid high-precision positioning device to the construction site; fix the positioning device on the outer circumference of the pipe pile to be measured through the fixing unit 2, and ensure that the positioning component 1 is located above the axis of the pipe pile;

[0066] S2: Start the measuring unit 4 and use the distance measuring sensor 401 to measure the distance between the positioning assembly 1 and multiple points on the outer circumference of the pile;

[0067] S3: Calculating the center position of the pipe pile based on the multi-point distances;

[0068] S4: By controlling the electric telescopic rod 402, the length of the electric telescopic rod 402 on the positioning assembly 1 is adjusted, and then the relative position of the positioning plate 101 is adjusted, so that the center of the positioning plate 101 is aligned with the center of the pipe pile, thereby achieving precise positioning.

[0069] In the specific implementation process, a pile center positioning test is conducted on a pipe pile with a diameter of 500 mm. The outer frame 102 of the positioning device used is a quadrilateral outer frame, and the positioning plate 101 is a square positioning plate. An electric telescopic rod 402 is respectively set in the middle of the four upper, lower, left and right frames of the outer frame 102. Each electric telescopic rod 402 is connected to a distance sensor 401, and the four distance sensors 401 are all high-precision laser distance sensors; the distance sensor 401 is set at the telescopic end of the electric telescopic rod 402.

[0070] During the test, the amount of movement of the positioning plate 101 is obtained. If the calculated result is a negative value, it means that the positioning plate 101 should be moved in the corresponding opposite direction.

[0071] First, check whether the remaining power of the device is sufficient for the test. Bring the device with sufficient power to the test site. Press the device switch 1022 and the screen of the host 1012 lights up. At this time, the four high-precision laser distance measuring sensors on the top, bottom, left and right sides are all activated, and start to obtain the distance data between the high-precision laser sensor and the outer wall of the pile in real time and send it to the host. The experimental data is:

[0072] The upper distance data measured by the upper high-precision laser sensor is 109.34mm, the distance data measured by the lower high-precision laser sensor is 91.00mm, the distance data measured by the left high-precision laser sensor is 109.35mm, and the distance data measured by the right high-precision laser sensor is 90.98mm; after the upper, lower, left and right high-precision laser sensors all start to obtain the measured distance, the host 1012 starts to automatically calculate the amount of upward movement of the positioning plate 101, and the calculation formula is: The amount of upward movement = (upper After calculating the amount of upward movement, the host 1012 automatically calculates the amount of left movement of the positioning plate 101, and the formula is that the amount of left movement = (left measured distance + right measured distance) / 2 - left measured distance, so the amount of left movement = (109.35mm + 90.98mm) / 2 - 109.35mm = -9.19mm.

[0073] After the host 1012 calculates the required upward movement amount and the left movement amount, the upper electric telescopic rod and the lower electric telescopic rod begin to drive the positioning plate 101 to move according to the required upward movement amount:

[0074] The host 1012 converts the data of the upward movement amount -9.17mm calculated by the distance measurement into the number of revolutions that the motors in the upper electric telescopic rod and the lower electric telescopic rod should rotate, and sends the corresponding data of the number of revolutions that the internal motors should rotate to the internal motors of the upper electric telescopic rod and the lower electric telescopic rod respectively;

[0075] The upper and lower electric telescopic rods begin to slowly push the positioning plate 101. At this time, the host 1012 and the four high-precision laser distance sensors continue to work to calculate the upward movement and leftward movement of the positioning plate 101. As the upper and lower electric telescopic rods slowly push the positioning plate 101, the upward movement data gradually increases from -9.17mm. After the upper and lower electric telescopic rods stop pushing together, if the upward movement is 0.00mm, it means that the positioning plate 101 has moved up to the corresponding compliance position. The host 1012 displays the data of up: 100.17mm, down: 100.17mm, and should move up 0.00mm; left: 109.19mm, right: 90.81mm, and should move left -9.19mm; if the amount of upward movement is not 0 after the upper electric telescopic rod and the lower electric telescopic rod stop pushing, the host will continue to control the upper electric telescopic rod and the lower electric telescopic rod to continue pushing the positioning plate 101 according to the data of the amount of upward movement until the amount of upward movement is 0mm.

[0076] After completing the calculation and movement of the upward movement, the electric telescopic rod 402 starts to drive the center of the positioning plate 101 and the center of the pile position to perform positioning calibration: the host 1012 converts the data of the upward movement amount -9.19mm obtained by the latest distance measurement into the number of revolutions of the motors in the left electric telescopic rod and the right electric telescopic rod, and sends the corresponding data of the number of revolutions of the internal motors to the internal motors of the left electric telescopic rod and the right electric telescopic rod respectively; at this time, the left electric telescopic rod and the right electric telescopic rod begin to slowly push the positioning plate 101, and the host 1012 and the four high-precision laser ranging sensors continue to work to calculate the positioning The amount of upward movement and the amount of left movement of plate 101; as the left electric telescopic rod and the right electric telescopic rod slowly push the positioning plate 101, the data of the amount of left movement gradually increases from -9.19mm. After the left electric telescopic rod and the right electric telescopic rod stop pushing, if the amount of left movement and the amount of upward movement are both 0mm, it means that the center of the positioning plate 101 has been aligned with the center of the pile position. At this time, the host 1012 displays the data as up: 100.00mm, down: 100.00mm, and the upward movement is 0.00mm; left: 100.00mm, right: 100.00mm, and the left movement is 0.00mm. At this time, the staff can place a handheld Beidou Cloud or other positioning instruments on the positioning hole 1011 and start measuring the pile position; if the left and right electric telescopic rods stop pushing, and the amount of movement to the left and the amount of movement to the upward are not both 0 mm at the same time, the host 1012 will continue to control the electric telescopic rod 402 to push the positioning plate 101 according to the data of the amount of movement to the left and the amount of movement to the upward until the amount of movement to the left and the amount of movement to the upward are both 0 mm.

[0077] The cross section of the pipe pile under actual conditions is approximately circular, and the number of high-precision laser ranging sensors can be increased (for example, the sensors in the four directions of up, down, left, and right are increased from 1 to 3), so that the host 1012 can obtain multiple groups of ranging data, and the obtained ranging data are averaged; the specific method is: the host 1012 first calculates the corresponding required movement amount using each group of ranging data, and then uses the average value of the required left movement amount and the required upward movement amount calculated by the required movement amount of each group of ranging sensors 401, and finally uses the average value of the required left movement amount and the required upward movement amount to drive the electric telescopic rod 402 to align the center of the positioning plate 101 with the center of the pile position, which can further improve the accuracy of the instrument in locating the center of the pile position.

[0078] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
