Technical Field
[0001] This invention relates to the field of prefabricated caisson verticality measurement technology, and in particular to a method, system, and storage medium for measuring the verticality of prefabricated caissons. Background Technology
[0002] In recent years, with the development of urban underground space and its rapid development, the application of caissons has become increasingly widespread. Compared with traditional caisson construction methods, the caisson construction method using precast segments for on-site assembly has gradually become popular. This caisson construction technology refers to assembling precast segments into a caisson on-site, replacing the traditional cast-in-place reinforced concrete caisson. However, during caisson sinking, differences in soil properties and uneven excavation can cause the caisson to tilt, severely affecting the construction progress. Unlike traditional reinforced concrete caissons, caissons using precast segments not only experience overall offset but also offset between adjacent upper and lower ring segments. Therefore, it is necessary to determine the verticality of each ring segment and the relative offset between rings for real-time adjustments during actual construction. Currently, there is no reliable method for determining these issues. Summary of the Invention

[0005] Furthermore, the coordinates of the lower surface of each remaining annular segment i on the y-axis and z-axis are measured and calculated. include: Measure the relative offset between each ring segment i and the adjacent lower ring segment i-1. And calculate the horizontal offset and the lower surface of the adjacent lower ring segment i-1 in the y-axis coordinate The coordinates of the lower surface of each of the aforementioned annular segments i on the y-axis are calculated using Formula 1. (Formula 1); Calculate the vertical offset between each ring segment i and the adjacent lower ring segment i-1. and the lower surface of the adjacent lower annular segment i-1 in the z-axis coordinate The coordinates of the lower surface of each of the aforementioned annular segments i on the z-axis are calculated using Formula 2. (Formula 2).
[0006] Furthermore, the relative offset The cracks are obtained by a crack gauge installed between adjacent annular segments.
[0007] Furthermore, the relative offset Defined as: along The positive direction of the axis is positive, along The negative axis is negative.
[0008] Furthermore, the horizontal offset The calculation steps include: Measure the tilt angle of the adjacent lower annular segment i-1. The horizontal offset is calculated using Formula 3. , (Formula 3).
[0009] Furthermore, the vertical offset The calculation steps include: Measure the tilt angle of the adjacent lower annular segment i-1. The vertical offset is calculated using formula 4. , (Formula 4).
[0010] Furthermore, the tilt angle The data is obtained through the inclinometer, which is installed on the outside of the ring segment.
[0011] Furthermore, the tilt angle Defined as: clockwise direction is positive angle, and counterclockwise direction is negative angle.
[0012] This invention provides a system for measuring the verticality of prefabricated assembled caissons, comprising: The acquisition module is used to obtain the radius of the caisson to be constructed. Thickness of each ring segment Height of each ring segment ; The coordinate module is used to establish a spatial rectangular coordinate system with the center of the caisson cross-section as the origin, and to obtain the coordinates of the lower surface of the lowest ring segment on the y-axis and z-axis. ; The measurement and calculation module is used to measure and calculate the coordinates of the lower surface of each remaining ring segment i on the y-axis and z-axis. ; The drawing module is used to plot the coordinates of each pipe segment.

[0013] The present invention provides a computer storage medium storing a computer program, which, when executed by a processor, implements the above-described method.
[0014] The beneficial effects of this invention are: First, by measuring the tilt angle of each ring segment with an inclinometer, the horizontal offset between adjacent ring segments can be calculated. Then, by measuring the relative offset between adjacent ring segments with a crack gauge, and combining the offset of the next layer of ring segments, the horizontal offset of each ring segment can be accurately determined.

This ensures the accuracy of the caisson's placement, guarantees the safety and accuracy of the project, and avoids losses. On the other hand, if construction problems occur, the attitude curve diagram can be used to identify the issues during the caisson sinking process, while also providing a reference for the research and development of caisson engineering.

[0021] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings. It should be understood that, unless otherwise specified, the order of the steps mentioned in this embodiment can be adjusted according to actual needs, and they can even be executed simultaneously or partially simultaneously.
[0022] This invention provides a method for determining the verticality of a prefabricated assembled caisson, comprising: S1 obtains the radius of the caisson to be constructed. Thickness of each ring segment Height of each ring segment ; In this step, the radius of the designed caisson is determined based on the actual needs of the project and the construction design plan. Thickness of the ring segment and height .
[0023] S2 as Figure 1 As shown, a spatial rectangular coordinate system is established with the center of the caisson cross-section as the origin, and the coordinates of the lower surface of the lowest ring segment on the y-axis and z-axis are obtained. ; In this step, such as Figure 1 As shown, with the center of the caisson's cross-section as the origin, the coordinate system is determined. axis, The axis is the vertical direction. To establish a spatial rectangular coordinate system, since the annular segment is a three-dimensional object, it is appropriate to establish a spatial rectangular coordinate system. Then, the lower surface of the bottom annular segment and the coordinate axis... The intersection point of the axes is ,in .
[0024] S3 measures and calculates the coordinates of the lower surface of each remaining ring segment i on the y-axis and z-axis. ; S301 measures the relative offset between each ring segment i and the adjacent lower ring segment i-1. And calculate the horizontal offset and the lower surface of the adjacent lower ring segment i-1 in the y-axis coordinate The coordinates of the lower surface of each of the aforementioned annular segments i on the y-axis are calculated using Formula 1. (Formula 1); The horizontal offset The calculation steps include: S3011 measures the tilt angle of the adjacent lower ring segment i-1. The horizontal offset is calculated using Formula 3. , (Formula 3).
[0025] In this step, such as Figure 2 As shown, taking the bottom ring segment and the second ring segment as examples, the tilt angle of the bottom ring segment is monitored using an inclinometer installed on the bottom ring segment. Where clockwise is considered positive and counterclockwise is considered negative, the horizontal offset of the bottom ring segment can then be calculated. The relative offset between the bottom and second ring segments was determined using a crack gauge installed between the bottom and second ring segments. Among them, along The positive direction of the axis is positive, along The negative direction of the axis is negative. Therefore, the coordinates of the second ring segment on the y-axis can be calculated. , The degree of horizontal displacement of the caisson can be accurately calculated using the formula.
[0026] S302 calculates the vertical offset between each ring segment i and the adjacent lower ring segment i-1. and the lower surface of the adjacent lower annular segment i-1 in the z-axis coordinate The coordinates of the lower surface of each of the aforementioned annular segments i on the z-axis are calculated using Formula 2. (Formula 2).
[0027] The vertical offset The calculation steps include: S3021 Measure the tilt angle of the adjacent lower ring segment i-1. The vertical offset is calculated using formula 4. , (Formula 4).
[0028] In this step, such as Figure 2 As shown, taking the bottom ring segment and the second ring segment as examples, the tilt angle of the bottom ring segment is monitored using an inclinometer installed on the bottom ring segment. The angle is defined as clockwise as positive and counterclockwise as negative. This allows for the calculation and determination of the vertical offset of the bottom ring segment. Therefore, the coordinates of the second ring segment on the z-axis can be calculated. , This calculation formula can accurately determine the degree of vertical offset of the caisson. S4 will set the coordinates of each segment. The verticality of the caisson is obtained by drawing a curve of the sinking process by connecting the lines.
[0029] This step will be explained using a real-world engineering example. Based on the actual needs of the project and the construction design plan, the diameter of the designed caisson will be determined. The thickness of each ring segment and height Therefore, the position of the lower surface of the bottommost ring segment can be determined. The inclination angles of each ring segment were measured by inclinometers installed on each ring segment. , , , , (Taking a 5-ring segment as an example). The relative offset between adjacent ring segments is measured by the cracks installed between each layer of segments. , , , .
[0030] Substituting into the horizontal offset formula, the horizontal offsets of each ring segment can be calculated as follows: , , , , Substituting into the vertical offset formula, the vertical offsets of the ring segments can be calculated as follows: , , , , .
[0031] like Figure 3 As shown, based on the above data for each ring segment, the coordinate positions of the lower surface of each ring segment on the y-axis and z-axis can be determined as follows: , , , , Based on the above coordinates, a sinking attitude curve diagram is drawn to determine the verticality of the caisson. The verticality of the five ring segments after construction can be directly obtained from the diagram, which facilitates subsequent construction adjustments, such as adjusting the sinking angle of the ring segments, and effectively avoids the overall caisson tilting caused by the offset of each ring segment.
[0032] The attitude curve during the sinking process can also be directly obtained from the intersection of the y-axis coordinates and the tilt angle of each ring segment. Draw it.
