Description

Technical Field

[0001] The invention relates to the technical field of digital modeling of vibro-stone piles, and in particular to a method, device and medium for generating a three-dimensional model of a vibro-stone pile. Background Art

[0002] The vibro-stone column composite foundation reinforcement technology originated in Europe in the 19th century. The technology is a construction process that uses a vibrator to make holes in soft clay and then fills them with stone blocks for reinforcement.

[0003] For large-scale infrastructure projects, deeper gravel piles are generally required, and the quality of gravel piles needs to be strictly inspected. Existing inspection methods all rely on discrete data and the measurement of single key indicators. This method is not comprehensive for evaluating the quality of gravel piles. At the same time, there is a lack of three-dimensional reconstruction technology for gravel piles, and visual-assisted quality assessment cannot be performed. At the same time, these discrete gravel pile data are difficult to apply to later analysis. The difficulty of three-dimensional digital reconstruction of gravel piles is that the gravel piles are buried underground, with only the top surface of the gravel pile exposed, and the geometric dimensions and other attribute parameters of the gravel piles cannot be obtained through effective direct measurement methods. Therefore, how to generate a three-dimensional model of vibro-compacted gravel piles is an important requirement for evaluating the quality of gravel piles. Summary of the invention

[0004] In order to solve the above technical problems, the present invention adopts the following solutions:

[0005] On the one hand, the method for generating a three-dimensional model of a vibro-stone column comprises the following steps:

[0006] S1: when making holes, the depth L1 of the hole introduction located at the 5th layer corresponding to the moment of terminating the hole introduction and the depth L2 of the hole creation located at the 4th layer corresponding to the moment of terminating the hole creation are calibrated respectively;

[0007] S2: When making piles, the weight of the gravel filler used when the pile length reaches |L2| is G2, the thickness of the filter section added between the 4th and 5th layers of gravel piles is L3, the weight of the gravel filler used when the pile length reaches |L1| is G1, and the radius of the gravel pile on the ground surface is r; the loose volume V2" of the gravel filler is calculated based on G2, the dense volume V2 of the gravel filler is calculated based on V2" and the density coefficient, the radius of the 4th layer of gravel pile is calculated based on V2 and |L2|, the loose volume V1" of the gravel filler is calculated based on G1, the dense volume V1 of the gravel filler is calculated based on V1" and the density coefficient, and the radius of the 5th layer of gravel pile is calculated based on V1 and |L1|.

[0008] S3: A plane rectangular coordinate system is established with the intersection of the ground and the central axis of the gravel pile as the origin O. Coordinate points are established in layers in the plane rectangular coordinate system, including the coordinates of the hole introduction section and the hole making section. The coordinates of the hole introduction section include: point A, point B, and point C. The coordinates of the hole making section include: point D and point E. The coordinates of point A are (r, 0), the coordinates of point B are (r1, (L1+L3) / 2), the coordinates of point C are (R, L1+L3), the coordinates of point D are (r2, L1), and the coordinates of point E are (r2, L1+L2). R is the radius of the preset hole (1) of the gravel pile.

[0009] S4: Generate a smooth curve function f(x) by smooth fitting the coordinates of point A, point B, point C, point D, and point E.

[0010] S5: Generate a spline curve in the three-dimensional model drawing software based on the smooth curve function f(x), and perform a rotation modeling operation on the spline curve to obtain a solid three-dimensional cylinder engineering file;

[0011] S6: The solid three-dimensional column engineering file is associated with the corresponding gravel pile number of the construction and then imported into the intelligent vibroflotation quality management platform.

[0012] Furthermore, the strata in the construction area are divided into 5 layers. When drilling, the 5th layer is penetrated first to complete the lead hole, and then the 4th layer is penetrated to complete the drilling. When the 3rd layer with good bearing capacity is reached, the drilling is finished.

[0013] S1 specifically includes:

[0014] S11: when the hole-drawing process is performed on the fifth layer, the hole-drawing termination time is determined according to the working condition parameters during the hole-drawing process, and the hole-drawing depth corresponding to the hole-drawing termination time is recorded as L1;

[0015] S12: when the hole-making process is performed on the fourth layer, the hole-making termination time is determined according to the working condition parameters during the hole-making process, and the hole-making depth corresponding to the hole-making termination time is recorded as L2;

[0016] The method of determining the termination time of hole drawing according to the working condition parameters during the hole drawing process is as follows: when "the upper limit of the starting depth of the 4th layer ≤ the hole drawing depth L1 ≤ the lower limit of the starting depth of the 4th layer", the vibration current is extracted, and the moment when the vibration current ≥ 5 / 4 of the layered mutation current is the moment of termination of hole drawing; the hole drawing depth L1 corresponding to the termination time of hole drawing is the boundary between the 5th layer and the 4th layer;

[0017] The method of determining the termination time of hole making according to the working condition parameters during the hole making process is as follows: when "the upper limit of the starting depth of the third layer ≤ the hole introduction depth L1 + the hole making depth L2 ≤ the lower limit of the starting depth of the third layer", the vibration current is extracted, and the moment when the vibration current ≥ 4 / 3 of the layered mutation current is the moment of termination of hole making; the hole introduction depth L1 + the hole making depth L2 corresponding to the termination time of hole making is the boundary between the fifth layer and the fourth layer;

[0018] The upper limit of the depth from the 4th layer, the lower limit of the depth from the 4th layer, the 5 / 4 layer mutation current, the upper limit of the depth from the 3rd layer, the lower limit of the depth from the 3rd layer, and the 4 / 3 layer mutation current are all geological exploration threshold data.

[0019] Further, V2 = V2"*ρ, ρ is the density coefficient, and r2 = √V2 / π |L2|; V1= V1"*ρ, ρ is the density coefficient, r1=√V1 / π |L1|.

[0020] Furthermore, the 5th, 4th and 3rd layers are all stratigraphic numbers. The 5th layer refers to the modern eroded sand-containing gravel layer al+plQ4 2 ; Layer 4 refers to the fine-grained soil layer of the barrier lake phase IQ4 1 ; The third layer refers to the alluvial deposit containing drifted sand and gravel layer alQ3 3 -2 .

[0021] Furthermore, the 3D model drawing software is AUTOCAD software, and the solid 3D column engineering file is a DXF format file; the intelligent vibro-flotation quality management platform scans the ASCⅡ content data of the solid 3D column object in the DXF format file; the intelligent vibro-flotation quality management platform generates a quality report based on the ASCⅡ content data of the solid 3D column object, and the intelligent vibro-flotation quality management platform loads the solid 3D column rendering display in the DXF format file.

[0022] Furthermore, the depth L2 and the depth L1 are obtained according to the calibration data of the winch rope on the vibratory impact device.

[0023] Further, the number of smooth curve functions f(x) is 1 or 2, and the number of corresponding spline curves is 1 or 2; when the number of smooth curve functions f(x) is 1, f(x) is a smooth curve function generated by smooth fitting the coordinates of point A, point B, point C, point D, and point E; when the number of smooth curve functions f(x) is 2, f(x) is a smooth curve function generated by smooth fitting the coordinates of point A, point B, and point C, and a smooth curve function generated by smooth fitting the coordinates of point C, point D, and point E;

[0024] Furthermore, when there are two smooth curve functions f(x), S5 is specifically as follows: based on the smooth curve function f(x), two spline curves are generated in the three-dimensional model drawing software, and the spline curves are rotated for modeling and merged into entities to obtain an engineering file including a solid three-dimensional column corresponding to the gravel pile of the boring section and a solid three-dimensional column corresponding to the gravel pile of the boring section, and a solid three-dimensional column after the two are merged into one entity.

[0025] In another aspect, the present invention provides a device for generating a three-dimensional model of a vibro-stone pile, comprising:

[0026] a memory for non-transitory storage of computer readable instructions;

[0027] The processor is used to execute the computer-readable instructions, and the computer-readable instructions, when executed by the processor, implement the method for generating a three-dimensional model of a vibro-stone pile.

[0028] On the other hand, a non-transitory computer-readable storage medium is provided, wherein the non-transitory computer-readable storage medium stores computer-readable instructions, and when the computer-readable instructions are executed by a processor, the method for generating a three-dimensional model of a vibro-stone pile is implemented.

[0029] The technical principles of the present invention are as follows:

[0030] In traditional technology, gravel piles are generally understood as column structures with uniform pile diameters. However, in the experimental research results of a certain university on the reinforcement mechanism of vibro-compacted gravel piles for composite foundations, it was found that during the construction of gravel piles, gravel vibro-compacting densification needs to be carried out in the borehole making section, and gravel vibro-compacting densification needs to be carried out in the borehole introduction section. At the same time, an anti-filtration section needs to be set between the two sections. Therefore, the study found that due to the deep stratum in the borehole making section and the high pressure of the surrounding soil layer, and the shallow stratum in the borehole introduction section and the low pressure of the surrounding soil layer, the pile diameter of the gravel pile in the upper borehole introduction section will expand upward at the anti-filtration section, while the pile diameter of the gravel pile in the upper borehole making section will remain uniform.

[0031] The calibration position of the anti-filtration section is determined by the boundary between the 5th and 4th layers. The existing technology generally determines the boundary between the 5th and 4th layers directly through geological survey. During operation, it is directly executed according to the boundary value of the 5th and 4th layers of the geological survey, resulting in all the 5th and 4th layers of the entire project The boundary has the same value, but in actual engineering, due to the variation of the strata, the boundary value of the 5th and 4th layers of the geological survey is not consistent with the actual boundary value of the 5th and 4th layers. Therefore, directly modeling with the boundary value of the geological survey will lead to inconsistency with the actual pile shape. Therefore, in order to achieve consistency with the actual situation.

[0032] The present invention adopts a dynamic method to determine the boundary between the 5th layer and the 4th layer, and regards the entire gravel pile as two dynamic large morphological segments, namely, the gravel pile of the boring section and the gravel pile of the boring section, wherein the dynamic boundary between the 5th layer and the 4th layer (depth L1) is first calibrated from the data generated in the boring process, and the dynamic boundary between the 5th layer and the 4th layer is used as a reference parameter for the subsequent pile making process, and the pile making process data is divided into two corresponding pile section intervals, and the amount of gravel added is divided into two parts according to the boundary, so that the pile radius of the two sections of gravel piles are calculated separately, and then the specific calibration positions are set separately according to the morphological conclusions of the pile diameters. For example, the gravel pile of the boring section is uniform according to the morphological research results, so it can be set as a uniform column according to the corresponding calculated pile radius, and the gravel pile of the boring section is upwardly extended according to the morphological research results. Therefore, the uniform median method is used to calibrate the pile radius; on this basis, we determine the radii of the upper and lower boundaries of the two sections of gravel piles, wherein, since in actual engineering operations, the anti-filtration section operation does not use vibration operations, but only fills the anti-filtration material, the pile diameter of this section has almost no change, but since it is necessary to perform vibration operations on the boring section, the pile diameter of this section will expand upward in a smooth transition manner. Therefore, within this interval, the present invention directly uses the preset hole radius of the gravel pile as the pile radius, and then directly measures the pile radius on the surface as the end point of the diameter expansion; therefore, multiple coordinate points of the upper and lower paths of the gravel pile are finally determined, and then a spline curve is obtained by smooth fitting. The spline curve represents the contour line of the pile. Finally, we use three-dimensional mapping software to perform three-dimensional operations on the contour line to obtain a three-dimensional column that is consistent with the actual operation.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. Fitting the gravel pile into two independent morphological regions is more in line with the final pile morphological results of actual engineering operations.

[0035] 2. The boundary between the 5th and 4th layers (depth L1) is determined by dynamic sampling to avoid the problem of poor consistency caused by the inconsistency between the fitting data and the stratification data caused by the actual formation mechanics.

[0036] 3. The method of morphological segmentation, direct surface measurement data, segmented estimation of pile diameter, and morphological trend centering to determine the boring section is adopted. The similarity between the fitted spline curve and the contour curve of the actual pile reaches more than 90%. Therefore, the constructed three-dimensional model can intuitively express the pile morphology, segmented pile diameter, surface parameters, change trend, stratigraphic stratification scale and other intuitive dimensions.

[0037] 4. Use CAD software to model the spline curve, then edit the 3D entity, and finally output and deliver it in DXF format. Use DXF to digitize the 3D model, which is conducive to subsequent system docking, data extraction and other information operations. When it is convenient for later quality correction, the 3D model parameters in DXF can be modified, and then the corrected 3D entity model can be created again in reverse (convert the modified DXF to dwg format), which improves the interactive convenience of the system.

[0045] Example 1

[0046] like Figure 1As shown, the method for generating a three-dimensional model of a vibro-stone pile comprises the following steps:

[0047] The method and device for generating a three-dimensional model of a vibro-stone pile comprises the following steps:

[0048] S1: when making holes, the depth L1 of the hole introduction located at the 5th layer corresponding to the moment of terminating the hole introduction and the depth L2 of the hole creation located at the 4th layer corresponding to the moment of terminating the hole creation are calibrated respectively;

[0049] Specifically, during the hole-guiding process on the 5th layer, the release depth of the winch and the vibratory current of the vibrator are recorded in real time. The two use a unified time dimension. When the release depth of the winch reaches between the upper limit of the depth at the beginning of the 4th layer and the lower limit of the depth at the beginning of the 4th layer, the vibratory current of the vibrator is observed. When the vibratory current is ≥5 / 4 of the layered mutation current, the hole-guiding process is terminated. At this time, the hole-guiding process is stopped, and the release depth of the winch corresponding to this moment is calibrated, which is defined as the hole-guiding depth L1, as follows: Figure 2 As shown, the lead-in depth of the hole is -8 meters. When the hole-making process is carried out in the 4th layer, the release depth of the winch and the vibration current of the vibrator are recorded in real time. The two use a unified time dimension. When the release depth of the winch reaches between the upper limit of the starting depth of the 3rd layer and the lower limit of the starting depth of the 3rd layer, the vibration current of the vibrator is observed. When the vibration current ≥ 4 / 3 of the layered mutation current is the moment of termination of hole-making, the hole-making process is stopped at this time, and the release depth of the winch corresponding to this moment is calibrated (-17 meters). The hole-making depth L2 is obtained by subtracting the lead-in depth L1 from the release depth of the winch, as shown in Figure 2 As shown, the lead hole depth of the hole is -9 meters. After the hole making process is completed, the hole making process 1 is formed, and then the pile making process is carried out.

[0050] S2: When making piles, the weight of the gravel filler used when the pile length reaches |L2| is G2, the thickness of the filter section added between the 4th and 5th layers of gravel piles is L3, the weight of the gravel filler used when the pile length reaches |L1| is G1, and the radius of the gravel pile on the ground surface is r; the loose volume V2" of the gravel filler is calculated based on G2, the dense volume V2 of the gravel filler is calculated based on V2" and the density coefficient, the radius of the 4th layer of gravel pile is calculated based on V2 and |L2|, the loose volume V1" of the gravel filler is calculated based on G1, the dense volume V1 of the gravel filler is calculated based on V1" and the density coefficient, and the radius of the 5th layer of gravel pile is calculated based on V1 and |L1|.

[0051] Specifically, the pile making process is divided into compaction and vibration pile making in the hole making section, placement in the anti-filtration section, and compaction and vibration pile making in the hole leading section. When the compaction and vibration pile making process is carried out in the fourth layer (hole making section), the pull-back scale of the winch and the weight of the gravel filler are recorded in real time. The two use the same time dimension. When the pull-back scale reaches |L2|, the pile length is recorded to reach |L2|, and the weight of the gravel filler at this moment is calibrated as G2. Then the pile radius of the fourth layer of gravel pile is calculated as r2, as shown in Figure 2 As shown, r2=0.41 meters is finally calculated based on the engineering parameters. During the anti-filtration section placement process, the thickness of the anti-filtration section L3 added between the 4th layer of gravel piles and the 5th layer of gravel piles is recorded. During the compaction vibration pile making process in the 5th layer (introduction hole section), the pull-back scale of the winch and the weight of the gravel filler are recorded in real time. The two use the same time dimension. When the pull-back scale reaches |L1|, the pile length is recorded to reach |L1|, and the weight of the gravel filler at this moment is calibrated as G1. Then the pile radius of the 4th layer of gravel piles is calculated to be r1, as shown in Figure 2 As shown in the figure, based on the engineering parameters, r1=0.53m is finally calculated. The system's own pile hole radius is R=0.3m. Finally, the pile radius of the gravel pile on the ground surface is measured to be r=0.61m.

[0052] S3: A plane rectangular coordinate system is established with the intersection of the ground and the central axis of the gravel pile as the origin O. Coordinate points are established in layers in the plane rectangular coordinate system, including the coordinates of the hole introduction section and the hole making section. The coordinates of the hole introduction section include: point A, point B, and point C. The coordinates of the hole making section include: point D and point E. The coordinates of point A are (r, 0), the coordinates of point B are (r1, (L1+L3) / 2), the coordinates of point C are (R, L1+L3), the coordinates of point D are (r2, L1), and the coordinates of point E are (r2, L1+L2). R is the radius of the preset hole (1) of the gravel pile.

[0053] Specifically, Figure 1 , Figure 2 As shown in the figure, by calibrating the construction process data with S2, the parameters in the depth direction are: L1, L3, L2, and the parameters in the radius direction are: r1, r2, r, R. According to the morphological division, the entire gravel pile can be divided into the lead-in section pile and the hole-making section pile. Among them, the hole-making section pile has no significant change in morphology, so r2, L1, L2 are used to calibrate the upper and lower contour boundary points of the hole-making section pile, and set point D and point E, whose coordinates are: the coordinate of point D is (r2, L1), and the coordinate of point E is (r2, L1+L2). Figure 2Specifically, the coordinates of point D are (0.41, -8), and the coordinates of point E are (0.41, -17); the lead hole section pile includes the anti-filtration section. Since the lead hole section pile will expand in shape, r1 can be a uniform value, and the uniform value is generally expressed by the midpoint. Therefore, the lead hole section pile is provided with a surface point A, a middle point B, and a starting point C of the anti-filtration section. The coordinates of point A are (r, 0), the coordinates of point B are (r1, (L1+L3) / 2), and the coordinates of point C are (R, L1+L3). Specifically, the coordinates of point A are (0.61, 0), the coordinates of point B are (0.53, -3.5), and the coordinates of point C are (0.3, -7).

[0054] So far, this embodiment has constructed a plurality of contour points corresponding to two morphological contours.

[0055] S4: Generate a smooth curve function f(x) by smooth fitting the coordinates of point A, point B, point C, point D, and point E.

[0056] S5: Generate a spline curve 2 in the three-dimensional model drawing software based on the smooth curve function f(x), and perform a rotation modeling operation on the spline curve to obtain a solid three-dimensional cylinder engineering file;

[0057] S6: The solid three-dimensional column engineering file is associated with the corresponding gravel pile number of the construction and then imported into the intelligent vibroflotation quality management platform.

[0058] On the basis of the above embodiment, the stratum in the construction area is divided into 5 layers. When drilling, the 5th layer is first penetrated to complete the lead hole, and then the 4th layer is penetrated to complete the hole making. When the 3rd layer with good bearing capacity is reached, the hole making is finished.

[0059] S1 specifically includes:

[0060] S11: when the hole-drawing process is performed on the fifth layer, the hole-drawing termination time is determined according to the working condition parameters during the hole-drawing process, and the hole-drawing depth corresponding to the hole-drawing termination time is recorded as L1;

[0061] S12: when the hole-making process is performed on the fourth layer, the hole-making termination time is determined according to the working condition parameters during the hole-making process, and the hole-making depth corresponding to the hole-making termination time is recorded as L2;

[0062] The method of determining the termination time of hole drawing according to the working condition parameters during the hole drawing process is as follows: when "the upper limit of the starting depth of the 4th layer ≤ the hole drawing depth L1 ≤ the lower limit of the starting depth of the 4th layer", the vibration current is extracted, and the moment when the vibration current ≥ 5 / 4 of the layered mutation current is the moment of termination of hole drawing; the hole drawing depth L1 corresponding to the termination time of hole drawing is the boundary between the 5th layer and the 4th layer;

[0063] The method of determining the termination time of hole making according to the working condition parameters during the hole making process is as follows: when "the upper limit of the starting depth of the third layer ≤ the hole introduction depth L1 + the hole making depth L2 ≤ the lower limit of the starting depth of the third layer", the vibration current is extracted, and the moment when the vibration current ≥ 4 / 3 of the layered mutation current is the moment of termination of hole making; the hole introduction depth L1 + the hole making depth L2 corresponding to the termination time of hole making is the boundary between the fifth layer and the fourth layer;

[0064] The upper limit of the depth from the 4th layer, the lower limit of the depth from the 4th layer, the 5 / 4 layer mutation current, the upper limit of the depth from the 3rd layer, the lower limit of the depth from the 3rd layer, and the 4 / 3 layer mutation current are all geological exploration threshold data.

[0065] On the basis of the above embodiment, V2= V2"*ρ, ρ is the density coefficient, r2=√V2 / π |L2|; V1= V1"*ρ, ρ is the density coefficient, r1=√V1 / π |L1|.

[0066] Based on the above embodiment, the 5th layer, the 4th layer and the 3rd layer are all stratigraphic numbers, and the 5th layer refers to the modern eroded gravel layer containing drifted sand. 2 ; Layer 4 refers to the fine-grained soil layer of the barrier lake phase IQ4 1 ; The third layer refers to the alluvial deposit containing drifted sand and gravel layer alQ3 3-2 .

[0067] Based on the above embodiment, the three-dimensional model drawing software is AUTOCAD software, and the solid three-dimensional cylinder engineering file is a DXF format file; the intelligent vibro-flotation quality management platform scans the ASCⅡ content data of the solid three-dimensional cylinder object in the DXF format file; the intelligent vibro-flotation quality management platform generates a quality report based on the ASCⅡ content data of the solid three-dimensional cylinder object, and the intelligent vibro-flotation quality management platform loads the solid three-dimensional cylinder rendering display in the DXF format file.

[0068] On the basis of the above-mentioned embodiment, the depth L2 and the depth L1 are obtained according to the calibration data of the hoisting rope of the hoist on the vibratory impact device.

[0069] On the basis of the above embodiment, the number of smooth curve functions f(x) is 1 or 2, and the number of corresponding spline curves is 1 or 2; when the number of smooth curve functions f(x) is 1, f(x) is a smooth curve function generated by smooth fitting of the coordinates of point A, point B, point C, point D, and point E; when the number of smooth curve functions f(x) is 2, f(x) is a smooth curve function generated by smooth fitting of point A, point B, and point C and a smooth curve function generated by smooth fitting of point C, point D, and point E;

[0070] On the basis of the above embodiment, when there are two smooth curve functions f(x), S5 is specifically as follows: based on the smooth curve function f(x), two spline curves are generated in the three-dimensional model drawing software, and the spline curves are rotated for modeling and merged into entities to obtain an engineering file including one solid three-dimensional column corresponding to the gravel pile of the boring section and one solid three-dimensional column corresponding to the gravel pile of the boring section, and one solid three-dimensional column after the two are merged into one entity.

[0071] Example 2

[0072] like Figure 3 , Figure 4 As shown,

[0073] In this embodiment, since it is necessary to extend the hole making to the third layer in a certain actual project, when making holes, the depth L1 of the hole introduction located in the fifth layer corresponding to the moment of terminating the hole introduction, the depth L2 of the hole making located in the fourth layer corresponding to the moment of terminating the hole making, and the depth L4 of the hole making located in the third layer corresponding to the moment of terminating the hole making are calibrated respectively.

[0074] Specifically, during the hole-guiding process on the 5th layer, the release depth of the winch and the vibratory current of the vibrator are recorded in real time. The two use a unified time dimension. When the release depth of the winch reaches between the upper limit of the depth at the beginning of the 4th layer and the lower limit of the depth at the beginning of the 4th layer, the vibratory current of the vibrator is observed. When the vibratory current is ≥5 / 4 of the layered mutation current, the hole-guiding process is terminated. At this time, the hole-guiding process is stopped, and the release depth of the winch corresponding to this moment is calibrated, which is defined as the hole-guiding depth L1, as follows: Figure 2 As shown, the lead-in depth of the hole is -8 meters. When the hole-making process is carried out in the 4th layer, the release depth of the winch and the vibration current of the vibrator are recorded in real time. The two use a unified time dimension. When the release depth of the winch reaches between the upper limit of the starting depth of the 3rd layer and the lower limit of the starting depth of the 3rd layer, the vibration current of the vibrator is observed. When the vibration current ≥ 4 / 3 of the layered mutation current is the moment of termination of hole-making, the hole-making process is stopped at this time, and the release depth of the winch corresponding to this moment is calibrated (-17 meters). The hole-making depth L2 is obtained by subtracting the lead-in depth L1 from the release depth of the winch, as shown in Figure 2 As shown, the drilling depth of the hole is -9 meters. When the drilling process is carried out on the third layer, the release depth of the winch and the vibration current of the vibrator are recorded in real time. The two use a unified time dimension. When the release depth of the winch reaches between the upper limit of the starting depth of the third layer and the lower limit of the starting depth of the third layer, the current descent depth of the vibrator is observed. When the current descent depth of the vibrator is ≥1 meter, the drilling is terminated. At this time, the drilling process is stopped, and the corresponding release depth of the winch at this moment is calibrated (-18 meters). The release depth of the winch minus the hole depth L1 minus the drilling depth L2 is obtained to obtain the drilling depth L4, as shown in Figure 3 As shown, the hole making depth of the hole is -1 meter. After the hole making process is completed, hole 1 is formed, and then the pile making process is carried out.

[0075] S2: When making piles, the weight of the gravel filler used when the pile length reaches |L2| is G2, the thickness of the filter section added between the 4th and 5th layers of gravel piles is L3, the weight of the gravel filler used when the pile length reaches |L1| is G1, and the radius of the gravel pile on the ground surface is r; the loose volume V2" of the gravel filler is calculated based on G2, the dense volume V2 of the gravel filler is calculated based on V2" and the density coefficient, the radius of the 4th layer of gravel pile is calculated based on V2 and |L2|, the loose volume V1" of the gravel filler is calculated based on G1, the dense volume V1 of the gravel filler is calculated based on V1" and the density coefficient, and the radius of the 5th layer of gravel pile is calculated based on V1 and |L1|.

[0076] Specifically, the pile making process is divided into compaction and vibration pile making in the hole making section, placement in the anti-filtration section, and compaction and vibration pile making in the borehole section. When the compaction and vibration pile making process is carried out in the fourth layer (hole making section), the pull-back scale of the winch and the weight of the gravel filler are recorded in real time. The two use the same time dimension. When the pull-back scale reaches |L2|, the pile making length is recorded to reach |L2|, and the weight of the gravel filler at this moment is calibrated as G2 (the weight of the gravel filler required for L4 needs to be subtracted from G2 at this time). Then, the pile radius of the fourth layer of gravel pile is calculated as r2, as shown in Figure 4 As shown, r2=0.78m is finally calculated based on the engineering parameters. During the anti-filtration section placement process, the thickness of the anti-filtration section added between the 4th layer of gravel piles and the 5th layer of gravel piles is recorded as L3=0.5m. During the compaction vibration pile making process in the 5th layer (hole section), the pull-back scale of the winch and the weight of the gravel filler are recorded in real time. The two use the same time dimension. When the pull-back scale reaches |L1|, the pile length is recorded to reach |L1|, and the weight of the gravel filler at this moment is calibrated as G1. Then the pile radius of the 4th layer of gravel piles is calculated as r1, as shown in Figure 4 As shown in the figure, based on the engineering parameters, r1=0.91m is finally calculated. The system's own pile hole radius is R=0.65m. Finally, the pile radius of the gravel pile on the ground surface is measured to be r=1.1m.
