Description

Technical Field

[0001] This invention relates to the field of engineering surveying technology, specifically to a self-priming fixed measuring device and method for pile location distance and angle. Background Technology

[0002] In actual pile foundation construction, due to the highly complex underwater geological conditions, the piling equipment on the water is affected by various external forces such as wind and waves during construction. After the piles are driven, the actual pile positions of the row of steel pipe piles at the front of the wharf differ significantly from the designed pile positions, making it difficult to keep the wharf shoreline straight and causing difficulties for mooring ships. The solution to this problem is to weld a standard straight frame with evenly spaced longitudinal pipes in front of the steel pipe piles. The frame consists of transverse pipes, longitudinal pipes, longitudinal fenders, and transverse fenders, with the longitudinal pipe spacing being the same as the designed steel pipe pile spacing.

[0003] In situations where there is a significant discrepancy between the actual pile positions and the designed pile positions for many completed piles, the measurement of the welding angle and length of the connecting pipe usually relies on manual measurement using measuring tools such as foundation tape measures. There is a lack of a tool specifically designed to measure the distance and angle between the existing steel column and the longitudinal pipe.

[0004] Therefore, in order to solve the above-mentioned technical problems in the existing technology, a self-priming fixed measuring device and method for pile distance and angle is proposed. Summary of the Invention

It solves the problem mentioned in the background art of the lack of a tool specifically designed to measure the distance and angle between the existing steel pile and the longitudinal pipe.

[0006] The present invention provides the following technical solution: a self-priming fixed measuring device for pile distance and angle, comprising an upper clamp and a measuring rope.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, please refer to Figures 1-4 A self-priming fixed measuring device for pile distance and angle includes an upper clamp 100 and a measuring rope 110. The upper clamp 100 is arc-shaped and fits against the circumferential surface of the existing pile steel column. The measuring rope 110 is straight, and the base points of several longitudinal pipes are located on the measuring rope 110. A first measuring mechanism 200 is provided on the upper clamp 100. The first measuring mechanism 200 is used to measure the distance and angle between the existing pile steel column and the longitudinal pipe.

[0033] The first measuring mechanism 200 includes a first arc-shaped groove 210 formed on the upper clamp 100, a first arc-shaped sliding column 220 slidably disposed in the first arc-shaped groove 210, an upper connecting plate 230 welded and fixed on the first arc-shaped sliding column 220, a thick tube 240 welded and fixed on the upper connecting plate 230, a tube ruler 250 slidably disposed in the thick tube 240, and a square ruler 260 fixedly installed on the upper clamp 100.

[0034] Align the ruler 250 with the base point of the longitudinal pipe, and measure the distance and angle between the existing steel column and the longitudinal pipe by reading the scale on the ruler 250 and the angle ruler 260.

[0035] The square 260 has several stake marks 270 on its circumference, the thick pipe 240 has measuring marks 280, and the thick pipe 240 is threaded with a tightening wire 290, which fixes the square 260.

[0036] It also includes a lower card 300, which has the same structure as the upper card 100. Both the upper card 100 and the lower card 300 are symmetrically provided with two magnets 310. The upper card 100 and the lower card 300 are fixed by welding with a vertical connector 320. The upper card 100 and the lower card 300 are magnetically fixed to the existing pile steel column by four magnets 310.

[0037] The lower card 300 has a second arc-shaped groove 330, and a second arc-shaped sliding column 340 is slidably disposed in the second arc-shaped groove 330. A lower connecting plate 350 is welded and fixed on the second arc-shaped sliding column 340, and the lower connecting plate 350 is welded and fixed to the upper connecting plate 230 through a diagonal brace 360.

[0038] In this embodiment: Figure 11 The existing pile 1 is connected to longitudinal pipe 1, existing pile 2 to longitudinal pipe 2, and existing pile 3 to longitudinal pipe 3. These are then welded together using connecting pipes 1, 2, and 3 to form a straight wharf shoreline. Only three piles are used here to illustrate the principle; in reality, there are many more steel piles, but the connection structure follows the same principle.

[0039] The upper clamp 100 and lower clamp 300 are made of steel pipe and are arc-shaped to match the outer circle of the steel pile. The upper clamp 100 and lower clamp 300 are fixed by welding with vertical connector 320. Four magnets 310 are fixed on the inner side of the ends of the upper clamp 100 and lower clamp 300. Arc-shaped grooves are machined on the upper clamp 100 and lower clamp 300.

[0040] Arc-shaped sliding columns are installed in the arc-shaped grooves of the upper clip 100 and the lower clip 300. The curvature of the arc-shaped sliding columns matches the arc-shaped upper clip 100 and the lower clip 300. The arc-shaped sliding columns can slide freely within the upper clip 100 and the lower clip 300. Upper and lower connecting plates 350 are welded to the upper and lower arc-shaped sliding columns. A thick pipe 240 is welded to the upper connecting plate 230. A diagonal brace 360 ​​is welded to the lower connecting plate 350. The other end of the diagonal brace 360 ​​is welded to the thick pipe 240. A pipe ruler 250 that can display the horizontal length is installed in the thick pipe 240. A tensioning wire 290 is provided on the thick pipe 240 to fix the pipe ruler 250 at any time.

[0041] The tripod, consisting of upper and lower arc-shaped sliding columns, upper and lower connecting plates 350, thick pipe 240, tightening wire 290, pipe ruler 250, and diagonal brace 360, can slide freely within the arc-shaped grooves of the upper clamp 100 and lower clamp 300. The device, consisting of the upper clamp 100, lower clamp 300, vertical connector 320, and four magnets 310, can be attached to the outer wall of the steel pile.

[0042] A square 260 is provided on the upper card 100 to display the horizontal angle, such as Figure 4As shown, a measuring mark 280 is provided on the upper connecting plate 230, and a pile mark 270 is marked on the steel pile. The center positions of many longitudinal pipes are marked on the straight measuring rope 110. The center distance of multiple longitudinal pipes is the standard design pile spacing, which is used to measure and determine the length and angle of each connecting pipe to meet the welding requirements between all steel piles and longitudinal pipes, and to achieve a straight wharf shoreline.

[0043] Before using the measuring device, first install the measuring rope 110 according to the technical drawings. Use measuring instruments to determine the elevation and horizontal position benchmark of each steel pile installation pipe on the shore. The benchmark should be as close as possible to the measuring rope 110. Mark the pile mark 270 of all steel piles.

[0044] The measurement procedure is as follows: First, align the zero point on the measuring device with the pile mark 270 of steel pile 1. Then, attach the four magnets 310 to the outer wall of steel pile 1 to fix the measuring device. Rotate the thick tube 240 to adjust the length of the tube ruler 250 to align with the center point of the longitudinal tube 1 marked on the measuring rope 110. Fix the tension wire 290 and read the data on the tube ruler 250, which is the length value of the connecting tube 1.

[0045] Next, align the measuring mark 280 with the angle ruler 260 marked on the upper card 100. This angle is the installation angle of connecting pipe 1. Mark this point on steel pile 1; this marked point is the installation center point of connecting pipe 1 on steel pile 1. Record the length and angle of connecting pipe 1. On land, cut and process the connecting lines to minimize the workload on water, which can greatly improve construction efficiency. After completing the measurement of existing pile 1, the measuring device can be easily removed to perform the measurement and construction of existing piles 2, 3, 4, etc., using the same measurement method.

[0046] Example 2, please refer to Figures 1-11 A second measuring mechanism 400 is installed on the vertical link 320. The second measuring mechanism 400 is used to measure the inclination angle of the existing pile steel column.

[0047] The second measuring mechanism 400 includes a digital level 410 fixedly installed on the vertical link 320. A first bubble level 420 is fixedly installed in the middle of the digital level 410. The first bubble level 420 is perpendicular to the vertical link 320. The inclination angle of the existing pile steel column can be measured by reading the bubble position of the first bubble level 420.

[0048] The digital level 410 has several grooves 430, which are linearly and equidistantly distributed. Probes 440 are slidably installed in each groove 430. The probes 440 are elastically connected to the inner wall of the grooves 430 by several springs 450. Displacement sensors 460 are installed in each groove 430.

[0049] When there are uneven areas on the existing steel pile, there is an error inclination angle between the vertical connector 320 and the existing steel pile. At this time, the displacement of several probes 440 when they contact the surface of the existing steel pile is measured to determine whether there is an error inclination angle.

[0050] The digital level 410 has a winding rod 470 installed on its internal thread. Several connecting ropes 480 are wound around the winding rod 470. One end of each connecting rope 480 is fixedly connected to the winding rod 470, and the other end of each connecting rope 480 is fixedly connected to several probes 440.

[0051] The digital level 410 is equipped with a digital display screen 490, through which the first inclination angle value of the existing steel column measured by the first bubble level 420 is read.

[0052] After several probes 440 have made contact with the surface of the existing steel column, for two adjacent probes 440, the lengths of the two probes 440 within the groove 430 measured by the displacement sensor 460 are set to L1 and L2 respectively, and the distance between the two probes 440 is set to L3. The second inclination angle value of the existing steel column is calculated by trigonometric functions and displayed on the digital display screen 490. Specifically, the second inclination angle value = arctan(L2-L1 / L3).

[0053] For every two adjacent probes 440, a second tilt angle value is calculated. If there is no error tilt angle, then all second tilt angle values ​​are equal.

[0054] The digital level 410 is also equipped with a second bubble level 500, which displays the third inclination angle value of the existing steel column measured by the second bubble level 500 through the digital display screen 490.

[0055] In this embodiment: the digital level 410 can be selected from various models according to actual needs. The first bubble level 420 located in the middle of the digital level 410 is a sealed glass tube that is in a horizontal state, filled with liquid, and contains a bubble.

[0056] As the digital level 410 is installed onto the existing steel column via the vertical connector 320, the bubble level moves due to the angle of the vertical connector 320. The electronic instruments inside the digital level 410 can read the bubble's position and directly display the tilt angle of the measured object on the digital display screen 490 installed on the digital level 410. When the existing steel column is vertical, the bubble is in the middle position, and the read tilt angle is 90°. In addition, two second bubble levels 500 installed on the left and right sides of the digital level 410 are used for auxiliary measurement and their angles can be adjusted by rotation. As this is prior art, the specific structure and working principle of the digital level 410 will not be described in detail.

[0057] Furthermore, considering that the upper clamp 100 or lower clamp 300 may have protrusions on the surface of the steel column that come into contact with the existing pile due to installation angle or unevenness on the steel column surface, which could cause an error between the angle of the vertical connection 320 and the overall angle of the existing pile, a calibration function has been added. Figure 9 and Figure 10 As shown, if the digital level 410 is not parallel to the surface of the steel column, but has an angle α, then the angle of inclination of the object measured by the digital level 410 will have an error, and the error value is the degree of the angle α.

[0058] At this point, the error can be calibrated by the second measuring mechanism 400. A row of equally spaced sliding grooves 430 is provided at the lower end of the digital level 410 along the left and right directions. Figure 9 The lines in the diagram can represent probes 440 that are slidably installed within the groove 430. By controlling several probes 440 to pop out of the steel column and contact the surface of the object being measured.

[0059] During this process, the displacement of several probes 440 can be measured by the displacement sensor 460, thereby calculating the length of each probe 440 extending out of the lower end of the digital level 410 and the length remaining inside the digital level 410. According to... Figure 10 As shown, the length of the second probe 440 from top to bottom inside the digital level 410 is set as L1, and the length of the third probe 440 from top to bottom inside the digital level 410 is set as L2. The distance between the two probes 440 is a known quantity L3. By comparing the difference between L2 and L1 with L3, the value of the tilt angle b can be calculated using trigonometric functions. The tilt angle b is equal to the tilt angle a. Based on the tilt angle of the measured object read by the first bubble level 420, the value of the tilt angle a is used for calibration to obtain the true tilt angle of the measured object.

[0060] Furthermore, each pair of adjacent probes 440 can measure a value for the tilt angle α. Multiple values, if within a small error range, can be averaged. If there is... Figure 9 If the first probe 440 from top to bottom contacts the protrusion, and the inclination angle α calculated by the first probe 440 and the second probe 440 has a large error compared with other values, then the value can be discarded.

[0061] Specifically, the function of controlling the ejection of several probes 440 is manually activated. When the calibration function is enabled, rotating the winding rod 470 releases several connecting ropes 480, causing several probes 440 to eject outward under the elastic force of several springs 450, and contact the surface of the steel column. Reverse rotation of the winding rod 470 winds several connecting ropes 480 onto the winding rod 470, at which point several probes 440 are stretched upward and stored inside the digital level 410.

[0062] Example 3, please refer to Figures 1-11 A measurement method for a self-priming fixed measuring device for pile distance and angle includes the following steps: First, the upper clip 100 and the lower clip 300 are attached to the circumferential surface of the existing pile steel column by four magnets 310. Then, the ruler 250 is rotated and stretched to be aligned with the center of the longitudinal pipe. The distance between the existing pile steel column and the longitudinal pipe is read by the ruler 250, the angle between the existing pile steel column and the longitudinal pipe is read by the angle ruler 260, and the inclination angle of the existing pile steel column is read by the digital display screen 490.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
