Description

Technical Field

[0001] This application relates to the field of engineering surveying technology, and in particular to an integrated measurement auxiliary device for engineering piles. Background Technology

[0002] With the continuous development of infrastructure technology in my country, the number of building floors is constantly increasing, leading to higher requirements for foundations, especially the widespread application of pile foundations and a growing number of engineering piles. However, the quality requirements for the construction of engineering piles are also rising, thus increasing the demand for and frequency of pile inspections. Therefore, improving the efficiency of engineering pile testing to meet the increasing needs is essential.

[0003] Traditional pile testing methods require measuring the pile core location, pile inclination, and pile diameter, with these three items measured separately.

[0004] Traditional pile core location measurement usually requires GNSS layout at the top of the pile foundation. This is not only inconvenient when the pile top is high, but also often increases measurement error due to inaccurate selection of the pile core location.

[0005] The tilt of the pile is usually measured by using a level on the sides of the pile in different directions. This method is not only inefficient and requires two measurements, but also requires the pile to be clean. If there are bumps on the pile surface, other smooth locations need to be found, which reduces the measurement efficiency.

[0006] The measurement of pile diameter, especially for traditional round piles, often requires multiple measurements to find the maximum chord length as the diameter. This not only results in low measurement efficiency but also makes it difficult to guarantee measurement accuracy, and is greatly influenced by individual subjectivity.

[0007] Regarding the aforementioned technologies, due to the large number of measurement items, especially the repeated measurement required for the diameter of round piles, the overall inspection efficiency of engineering piles is low. Summary of the Invention

[0008] To improve the efficiency of testing engineering piles, this application provides an integrated measurement auxiliary device for engineering piles.

[0009] The integrated measurement auxiliary device for engineering piles provided in this application adopts the following technical solution: An integrated measurement auxiliary device for engineering piles includes a column and a positioning component mounted on the column. The positioning component includes two connecting rods, both of which are connected to the column and form a right angle between them. A positioning block is provided at the end of each connecting rod furthest from the column. The end of the positioning block closest to the right angle formed by the two connecting rods protrudes from the connecting rod, and the end of the positioning block closest to the right angle formed by the two connecting rods is a corner point used to abut against the periphery of the pile. A laser rangefinder is mounted on the column and is used to measure the distance between the center of the column and the periphery of the pile.

[0010] By adopting the above technical solution, when measuring the pile diameter, if the pile body is small, the pile body is tangent to the connecting rod. When the pile body is tangent to the connecting rod, a measuring tape is used to directly measure the point of tangency between the center of the column and the pile body. The measured distance is the pile diameter. If the pile body is large, the corner point is made to contact the periphery of the pile body being measured. When the pile body is tangent to the corner point, a laser rangefinder is activated. The laser rangefinder measures the distance between the center of the column and the periphery of the pile body. After measurement, the pile diameter is calculated based on the data measured by the laser rangefinder and the Pythagorean theorem, thereby improving the efficiency of engineering pile inspection.

[0011] Optionally, the column includes a first fixing block, a second fixing block, and a support rod. The first fixing block is located above the second fixing block and is coaxially arranged with the second fixing block. The support rod is located between the first fixing block and the second fixing block, and both ends of the support rod are connected to the first fixing block and the second fixing block, respectively. The laser rangefinder is located on the top of the second fixing block.

[0012] By adopting the above technical solution, the column is connected to the first fixed block and the second fixed block by the support rod, which can reduce the weight of the measuring device and facilitate the operator's measurement. At the same time, the laser rangefinder is set on the top of the second fixed block, which reduces the possibility of the pile hitting the laser rangefinder and extends the service life of the laser rangefinder.

[0013] Optionally, the positioning block includes an installation block and a fixing block. The installation block is located at the end of the connecting rod away from the column. One end of the fixing block is detachably connected to the installation block, and the other end faces the right angle formed by the two connecting rods. The fixing block and the connecting rod also have a right angle. The end of the fixing block away from the installation block is provided with a first scale.

[0014] By adopting the above technical solution, one end of the positioning block can be detachably connected to the installation block, which facilitates the replacement of worn positioning blocks. The first scale set on the positioning block facilitates the reading of the tangency point data when the pile body is tangent to the positioning block.

[0015] Optionally, two fixing components are provided, which are respectively connected to the first fixing block and the second fixing block. The two fixing components form a placement area for placing the pile.

[0016] By adopting the above technical solution and setting two fixed-point components, all four corner points are in contact with the pile body, which improves the stability of the pile body measurement and also improves the accuracy of the pile body measurement.

[0017] Optionally, a slider is slidably connected to the connecting rod, the sliding direction of the slider is the same as the length direction of the connecting rod, and a fixing bolt is provided on the slider to fix the position of the slider on the connecting rod.

[0018] By adopting the above technical solution, when measuring the verticality of the pile, the level is placed vertically on the slider, and the value on the level is read and calculated, which facilitates the measurement of the verticality of the pile. The fixing bolt makes it easy to fix the slider at any position on the connecting rod, which is convenient for placing the level.

[0019] Optionally, a placement gap is formed between the two sliders on the same side of the two positioning components, the placement gap being used to place a level.

[0020] By adopting the above technical solution, when measuring the verticality of the pile, a level is placed between two sliders, so that the two sliders can fix the level, making it easy for the operator to record the data on the level, and thus making it easy to calculate the verticality of the pile based on the angle between the data on the level and the direction of gravity.

[0021] Optionally, the positioning component further includes a scale rod, one end of which is connected to the column and the other end of which is connected to the positioning block. The scale rod is parallel to the connecting rod and has a second scale on it. The second scale and the first scale are continuous scale values.

[0022] By adopting the above technical solution, when the pile body is small, the pile body is tangent to the scale rod. When the pile body is tangent to the scale rod, the value of the tangent point between the pile body and the scale rod is directly read. The value of the tangent point is the pile diameter. The second scale makes it easy to read the pile diameter value.

[0023] Optionally, a GNSS measuring instrument is provided on the top of the column.

[0024] By adopting the above technical solution, the GNSS measuring instrument is used to measure the position of the pile core. Combined with the actual measured pile diameter, it is easy to calculate the deviation data between the actual measured and designed pile core positions, thereby facilitating the acquisition of pile offset data.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up columns and fixed-point components, when measuring the pile diameter, the corner point of the fixed-point component is brought into contact with the pile body, and a laser rangefinder is used for measurement. Finally, the distance between the corner point and the pile diameter is calculated based on the data measured by the laser rangefinder and the distance between the corner point and the pile diameter. This facilitates the detection of the pile diameter and improves the detection efficiency of engineering piles. 2. By setting a slider, it is easy to place a spirit level on one side of the pile to check the verticality of the pile; 3. By setting two sets of fixed-point components, the stability of the measuring device when it contacts the side wall of the pile is improved, thereby improving the accuracy of the detection data.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses an integrated measurement auxiliary device for engineering piles, referring to... Figure 1An integrated measurement auxiliary device for engineering piles includes a column 1 and a positioning component 2 mounted on the column 1. The column 1 is cylindrical. The positioning component 2 includes two connecting rods 21, both of which are welded to the periphery of the column 1. The two connecting rods 21 are cylindrical rods of equal length and form a right angle between them. A positioning block 23 is welded to the end of each connecting rod 21 away from the column 1. The end of the positioning block 23 near the right angle formed by the two connecting rods 21 protrudes from the connecting rod 21. The end of the positioning block 23 near the right angle formed by the two connecting rods 21 is a corner point 3, which is used to abut against the periphery of the pile body 6. A laser rangefinder 4 is fixedly connected to the column 1 by bolts. The laser rangefinder 4 is a miniature laser rangefinder used to measure the distance between the center of the column 1 and the periphery of the pile body 6. A GNSS measuring instrument 5 is fixedly connected to the top of the column 1 by bolts. The GNSS measuring instrument 5 is used to locate the center of the pile body 6.

[0031] Reference Figure 2 When measuring the smaller diameter of pile 6, the pile diameter is the radius of pile 6. When corner point 3 abuts against the periphery of pile 6, pile 6 is tangent to connecting rod 21. Use a measuring tape to measure the point of tangency between the center of column 1 and pile 6. The measured distance k is the pile diameter of pile 6, i.e., r = k.

[0032] Reference Figure 3 When measuring a pile 6 with a larger diameter, the corner point 3 is brought into contact with the circumferential wall of the pile 6. The reading k is the point where the center of the column 1 is tangent to the pile 6 and the corner point 3. The laser rangefinder 4 is then activated, and it measures the distance c between the center of the column 1 and the circumferential wall of the pile 6. Therefore: The pile diameter of pile 6 can be calculated using the formula. The laser rangefinder 4 measures the distance between the side wall of pile 6 and the center of column 1. The measurement efficiency and accuracy are both high.

[0033] Reference Figure 4 When measuring a pile 6 with a larger diameter, the corner point 3 is brought into contact with the peripheral wall of the pile 6 being measured. The measuring distance between the corner point 3 and the center of the pile is r. A laser rangefinder 4 is used to measure the distance c between the center of the column 1 and the center of the pile. According to the Pythagorean theorem, we have... After simplification By selecting the appropriate formula for calculation based on the contact situation between pile body 6 and corner point 3 with piles of different diameters, the laser detector can quickly measure the data required for calculation, thereby improving the detection efficiency of engineering piles.

[0034] Reference Figure 5The column 1 includes a first fixing block 11, a second fixing block 12, and a support rod 13. The first fixing block 11 is located above the second fixing block 12 and is coaxially arranged with the second fixing block 12. The support rod 13 is located between the first fixing block 11 and the second fixing block 12, and both ends of the support rod 13 are welded to the first fixing block 11 and the second fixing block 12, respectively. In this embodiment, the support rod 13 consists of three cylindrical rods of equal length. The laser rangefinder 4 is fixedly connected to the upper surface of the second fixing block 12 by bolts. To improve the stability of the positioning block 23, in this embodiment, two connecting rods 21 are welded to the same side of the first fixing block 11 and the second fixing block 12, and the two connecting rods 21 on the same side are arranged vertically in the same plane. A grip handle is provided on one side of the first fixing block 11 and the second fixing block 12. The grip handle is C-shaped, with one end welded to the peripheral wall of the first fixing block 11 and the other end welded to the peripheral wall of the second fixing block 12.

[0035] Reference Figure 5 To improve the stability of the measuring device on the sidewall of the pile 6, corner points 3 are added to contact the pile 6. Two fixing components 2 are provided, which are respectively connected to the first fixing block 11 and the second fixing block 12. The two fixing components 2 form a placement area 24 for placing the pile 6. When the pile 6 is being tested, the four corner points 3 can be used to contact the smooth parts of the sidewall of the pile 6 for measurement, reducing the possibility of protrusions on the sidewall of the pile 6 affecting the measurement results and improving the detection accuracy of the pile 6.

[0036] Reference Figure 5 The connecting rods 21 in the two fixed-point components 2 are parallel to each other. A slider 25 is slidably connected to the connecting rod 21. The connecting rod 21 passes through the slider 25. The upper surface of the slider 25 is a horizontal plane, so that a spirit level can be placed on the slider 25 to measure the verticality of the pile 6. The sliding direction of the slider 25 is the same as the length direction of the connecting rod 21. A fixing bolt 26 is threaded on the slider 25. The fixing bolt 26 is a knob bolt. The fixing bolt 26 is used to fix the position of the slider 25 on the connecting rod 21.

[0037] Reference Figure 5 A placement gap 27 is formed between the two sliders 25 on the same side of the two fixed-point components 2. The placement gap 27 is used to place the level. When measuring the verticality of the pile 6, the two ends of the level are respectively clamped between the upper surface of the lower slider 25 and the lower surface of the upper slider 25. The two sliders 25 on the same side fix the level, so that the level is vertically set between the two sliders 25, which improves the stability of the level on the sliders 25 and makes it easier for the operator to check the verticality of the pile 6.

[0038] Reference Figure 5The positioning component 2 also includes a scale rod 22, which is positioned near the placement area 24. One end of the scale rod 22 is welded to the column 1, and the other end is welded to the positioning block 232. The scale rod 22 is parallel to the column, and a second scale 221 is engraved on it. In this embodiment, the longitudinal section of the scale rod 22 is an isosceles triangle, that is, the upper surface of the scale rod 22 is a downward sloping surface, in order to reduce the possibility of dust, dirt, and other debris accumulating on the scale rod 22.

[0039] Furthermore, referring to Figure 5 The positioning block 23 includes a mounting block 231 and a fixing block 232, both of which are cuboid in shape. The mounting block 231 is welded to the end of the connecting rod 21 away from the column 1. One end of the fixing block 232 is detachably connected to the mounting block 231, and the other end faces the right angle formed by the two connecting rods 21. The fixing block 232 can be detachably connected by bolts or by snap-fit ​​connection. In this embodiment, it is snap-fit ​​connection. The fixing block 232 also has a right angle with the connecting rod 21. The end of the fixing block 232 away from the mounting block 231 is engraved with a first scale 233. The scale direction of the first scale 233 is the same as the scale direction of the measuring ruler, and the scale values ​​of the first scale 233 and the second scale 221 on the measuring ruler are continuous values.

[0040] The implementation principle of the integrated measurement auxiliary device for engineering piles in this embodiment is as follows: When measuring a pile 6 with a smaller diameter, the pile 6 is placed in the placement area 24, so that all corner points 3 abut against the peripheral wall of the pile 6. At this time, the pile 6 is tangent to the scale rod 22. The value at the point of tangency between the pile 6 and the second scale 221 on the scale is read, and the read value is the pile diameter of the smaller pile 6. When measuring a pile 6 with a larger diameter, the pile 6 is placed in the placement area 24, so that all four corner points 3 abut against the peripheral wall of the pile 6. At this time, the pile 6 is tangent to the corner point 3 of the fixed point block 232. The value at the point of tangency between the pile 6 and the fixed point block 232 is read. The distance between the center of the second fixed block 12 and the periphery of the pile 6 is then measured using a laser rangefinder 4. The data from the laser rangefinder 4 is combined with the readings of the tangent point between the pile 6 and the fixed block 232 to calculate the pile diameter of the pile 6. The GNSS measuring instrument 5 is used to locate the center of the pile 6 and measure the deviation between the center position and the designed center position to determine the pile offset. A level is placed on the slider 25, and the verticality of the pile 6 is measured according to the angle between the level and the direction of gravity. Through the integrated detection device, multiple data of the pile 6 can be measured, and the measurement process is simple to operate, thereby improving the detection efficiency of engineering piles.
