Description

Technical Field

[0001] The invention relates to the technical field of pipe pile customization, and in particular to a method for accurately customizing the length of a pipe pile. Background Art

[0002] Pipe piles, as an indispensable prefabricated component in modern construction projects, are manufactured in strict accordance with the precise guidance of the prestressing process and centrifugal forming method. This hollow cylindrical slender concrete prefabricated component is mainly composed of key parts such as the cylindrical pile body, the end plate and the steel sleeve, ensuring that it can still maintain excellent stability and bearing capacity when subjected to huge pressure.

[0003] When conducting trial driving of pile foundation, in order to ensure the quality and safety of the project, the pile pressing process of the pipe pile usually follows the dual control standard of final pressure as the main method and the designed pile length as the auxiliary method. This is because the final pressure can intuitively reflect the compaction of the pipe pile underground, while the designed pile length is a standard pre-set according to geological conditions and project requirements. In the actual construction process, in order to ensure that the final pressure meets the design requirements, the construction personnel will pay close attention to the reading of the pressure gauge, and use it as the basis for final pressure control after the load or re-pressure is stable.

[0004] However, due to the complexity and variability of geological conditions, the pile length often varies depending on the geological conditions. This leads to a common problem: when the pipe pile reaches the final pressure condition, the actual pile top elevation often deviates from the designed pile top elevation. Some may be higher than the designed elevation, resulting in over-delivery of piles; others may be lower than the designed elevation, requiring pile cutting. This deviation not only increases the difficulty of construction, but may also have an adverse impact on the quality of the project.

[0005] Therefore, during the construction of pipe piles, how to accurately control the pile top elevation and avoid over-delivery or excessive cutting of pile lengths has become a key issue for construction personnel to consider. In order to solve this problem, construction personnel need to fully survey and analyze the geological conditions before construction, reasonably formulate a construction plan, and ensure that every parameter in the pile driving process can be accurately controlled.

[0006] Based on the above problems, the present invention proposes a method for accurately customizing the length of pipe piles to achieve accurate matching of pipe piles to a target length. Summary of the invention

[0007] In order to solve the above problems, the present invention aims to provide a technical solution that can solve the above problems.

[0008] A method for accurately customizing the length of a pipe pile, comprising the following steps: (1) Analyze land samples at fixed points and generate geological survey reports, draw BIM geological models and pipe pile structure models: (2) Determine the depth of the pile model into the rock: By analyzing the 3D geological model and the pipe pile structure model, determine the rock layer and its depth that the pipe pile model needs to pass through; (3) Select the test pile and collect the pressure value: Select plots with similar geology in the region, designate test piles on these plots, conduct pressure tests on the test piles, and collect pressure value data under different rock formations; (4) Draw a pressure curve: With the pressure value as the X-axis and the thickness of the rock layer as the Y-axis, a rectangular coordinate system is established, and according to the pressure value data collected in step (3), pressure curves of the test piles are drawn in the coordinate system respectively; (5) Integrate the pressure curve diagram and draw the pressure curve of the customized pile: The pressure curves of the test piles are integrated to obtain a linear pressure curve reflecting the overall geological conditions. Based on the linear pressure curve, the pressure curve of the pipe piles to be customized is drawn; (6) Analyze the pressure curve of the pipe pile to be customized. The difference between the soil layer elevation at which the final pressure value is reached and the ground elevation is the length of the pipe pile to be customized.

[0009] Furthermore, step (1) specifically includes selecting a plurality of representative land sample points in the predetermined construction area for detailed geological survey, understanding the geological structure, soil type, rock distribution, etc. of the construction area and recording the geological survey report, and drawing a three-dimensional geological model and a pipe pile structure model using BIM technology based on the geological survey report.

[0010] Furthermore, the pressure curve of the pipe pile to be customized in step (5) is drawn by the following method: taking the boundary depth of each rock layer that the pipe pile to be customized needs to pass through as the base point, drawing straight lines intersecting with the linear pressure curve, and these intersection points are used as key points of the pressure curve of the pipe pile to be customized. These key points are connected to obtain the pressure curve of the pipe pile to be customized.

[0011] Furthermore, in step (1), a three-dimensional geological model and a pipe pile structure model are created using Revit software.

[0012] Furthermore, in step (3), the pressure value is recorded every time the test pile is driven 1 m.

[0013] Furthermore, in step (3), at least two test piles are designated in a geologically similar plot.

[0014] Furthermore, in step (5), a linear regression method is used to integrate the pressure curves of the test pile 1 and the test pile 2 and obtain a linear pressure curve.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By comprehensively using geological surveys, BIM technology and data analysis, the precise customization of the length of the pipe piles is achieved. This method can not only improve construction efficiency and reduce engineering risks, but also optimize resource allocation and improve engineering quality.

[0025] Under the guidance of the concept of the present invention, a construction site adopts the method for accurately customizing the length of pipe piles of the present invention, which specifically includes the following steps: (1) Analyze land samples at fixed points, generate geological survey reports, draw BIM geological models based on the geological survey reports, and establish three-dimensional geological models and pipe pile structure models; First, select multiple representative land sample points in the planned construction area for detailed geological survey. By analyzing these sample points, an accurate geological survey report can be generated to understand the geological structure, soil type, rock distribution, etc. of the construction area; According to the geological survey report, the three-dimensional geological model and the pipe pile structure model are drawn using BIM (Building Information Modeling) technology. These two models will provide basic data for subsequent analysis and calculation. When building the model, special attention should be paid to the precision and accuracy of the model to ensure the smooth progress of subsequent steps. When drawing the BIM geological model and the pipe pile structure model, the Geographic Information System (GIS) and other related software can be used to assist in the completion; (2) Determine the depth of the pile model into the rock: By analyzing the 3D geological model and the pile structure model, the rock layer that the pile model needs to penetrate and its depth can be determined; (3) Analyze the geologically similar plots in the region, designate two test piles in different regions, label them as test pile one and test pile two, and collect the pressure values ​​of the on-site test piles; Select plots with similar geology in the region and designate two test piles on each of these plots, labeled as test pile one and test pile two. Then, perform pressure tests on the two test piles to collect pressure value data under different rock layers. (4) With the pressure value as X and the rock layer thickness as Y, a rectangular coordinate system is established. Based on the pressure value data collected in step (3), pressure curves for test pile 1 and test pile 2 are drawn respectively, as shown in Fig. Figure 1 , Figure 2 As shown; (5) Figure 3 As shown, the pressure curves of the test pile 1 and the test pile 2 obtained in step (4) are integrated to obtain the following Figure 4 The linear pressure curve shown in FIG. 1 is based on the linear pressure curve diagram, and a straight line intersecting the linear pressure curve line is drawn in the X direction with the intersection depth of each rock layer required to be passed through by the customized pipe pile as the base point. The intersection point of the line segment corresponding to the rock layer on the linear pressure curve and the straight line corresponding to the rock layer is used as the base point to connect the lines to obtain the following: Figure 5 The pressure curve of the pipe pile to be customized is shown; (6) Analyze the pressure curve of the pipe pile to be customized. The difference between the soil layer elevation at which the final pressure value is reached and the ground elevation is the length of the pipe pile to be customized.

[0026] The method for accurately customizing the length of pipe piles provided by the present invention mainly has the following effects: 1) Accurately determine the pile length: By analyzing land samples at fixed points, generating geological survey reports and BIM geological models, we can accurately understand the geological conditions of the construction area and provide reliable data support for determining the length of pipe piles.

[0027] Draw the pipe pile structure model and determine the rock penetration depth to further ensure that the pile length can meet the geological conditions and design requirements.

[0028] 2) Improve construction efficiency: Selecting plots with similar geology in the region for test pile testing can collect effective pressure value data more quickly and shorten the preliminary preparation time.

[0029] The use of BIM technology and pressure curves to determine pile length improves the accuracy and efficiency of the analysis process.

[0030] 3) Reduce engineering risks: Through detailed land surveys and geological modeling, it is possible to more accurately predict the problems that may be encountered during the construction of pipe piles, such as rock layer changes, soil bearing capacity, etc., so that corresponding measures can be taken in advance to reduce engineering risks.

[0031] Drawing a pressure curve diagram and determining the pressure curve of the custom-made piles helps ensure that the piles can withstand sufficient pressure during construction to avoid damage to the pile body or construction failure.

[0032] 4) Optimize resource allocation: Accurately determining pile length can reduce unnecessary material waste and labor input, and reduce project costs.

[0033] Optimizing the design of pipe piles according to the pressure curve can ensure that the strength and stiffness of the pile body meet the requirements, while reducing the weight and volume of the pile body to facilitate transportation and installation.

[0034] 5) Improve project quality: Accurately controlling the pile length can ensure that the pipe pile has sufficient bearing capacity and stability when passing through different rock formations, thereby improving the overall quality of the foundation project.

[0035] Through trial pile testing and data analysis, the design parameters and construction methods of pipe piles can be continuously optimized to improve the reliability and durability of the entire project.

[0036] In short, the above method realizes the precise customization of the length of pipe piles by comprehensively using geological survey, BIM technology and data analysis. This method can not only improve construction efficiency and reduce engineering risks, but also optimize resource allocation and improve engineering quality. It is an indispensable part of modern construction projects.

[0037] On the basis of analyzing land samples at fixed points and generating geological survey reports, professional BIM (Building Information Modeling) software such as Revit is used to create 3D geological models and pipe pile structure models. With its powerful 3D modeling capabilities and rich tool sets, Revit software can accurately convert geological data in geological survey reports into 3D visualized geological models. At the same time, through parametric design, pipe pile structure models that meet design requirements can be quickly created. These two models provide intuitive and accurate data support for subsequent analysis and calculations.

[0038] By analyzing the 3D geological model and the pipe pile structure model, we can accurately determine the rock layer and its depth that the pipe pile model needs to pass through. This is the basis for subsequent calculations and designs, ensuring that the pipe pile can safely and stably pass through each rock layer during actual construction.

[0039] When analyzing plots with similar geology in the region, two test piles are designated: Test Pile 1 and Test Pile 2. During the driving of these two test piles, the pressure value is recorded every 1m. In this way, sufficiently detailed and accurate pressure value data are collected, which are used for subsequent pressure analysis and calculations.

[0040] A rectangular coordinate system is established with the pressure value as the X-axis and the thickness of the rock layer as the Y-axis. Then, based on the collected pressure value data, pressure curves for test pile 1 and test pile 2 are drawn in the coordinate system. These curves intuitively show how the pressure changes with the thickness of the rock layer, providing reference information for determining the length of the pipe pile to be customized.

[0041] When integrating the pressure curves of test pile 1 and test pile 2, the linear regression method is used. This method is based on the existing data points and mathematically fits the best linear pressure curve. This curve reflects the overall relationship between pressure and rock layer thickness, providing an important basis for determining the length of the pipe pile to be customized.

[0042] Based on the linear pressure curve, with the intersection depth of each rock layer that the custom-made pile needs to pass through as the base point, draw a straight line that intersects with the linear pressure curve in the X direction. Then, connect the line segment corresponding to the rock layer on the linear pressure curve with the intersection point of the straight line corresponding to the rock layer as the base point, and finally get the pressure curve of the custom-made pile. This curve provides accurate guidance for determining the specific pile length.

[0043] The details of the exemplary embodiments described above are not limited to the embodiments described above, and the invention may be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive in all respects, and the scope of the invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
