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 overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0008] The method for accurately customizing the length of pipe piles specifically includes the following steps:

[0009] (1) Analyze land samples at fixed points and generate geological survey reports, draw BIM geological models and pipe pile structure models:

[0010] (2) Determine the rock penetration depth position of the pipe pile model:

[0011] By analyzing the three-dimensional geological model and the pipe pile structure model, determine the rock layers that the pipe pile model needs to penetrate and their depth positions;

[0012] (3) Select test piles and collect pressure values:

[0013] Select plots with similar geology in the area, and respectively designate test piles on these plots. Conduct pressure tests on the test piles and collect pressure value data under different rock layers;

[0014] (4) Draw a pressure curve graph:

[0015] Taking the pressure value as the X-axis and the thickness of the penetrated rock layer as the Y-axis, establish a rectangular coordinate system. According to the pressure value data collected in step (3), draw the pressure curve graphs of the test piles in the coordinate system respectively;

[0016] (5) Integrate the pressure curve graphs and draw the pressure curve of the pipe pile to be customized:

[0017] Integrate the pressure curve graphs of the test piles to obtain a linear pressure curve reflecting the overall geological conditions. Based on the linear pressure curve, taking the intersection depth of each rock layer that the pipe pile to be customized needs to penetrate as the base point, draw a straight line that intersects the linear pressure curve in the X direction. Connect the intersection points of the line segments corresponding to the rock layers on the linear pressure curve and the straight lines corresponding to the rock layers to obtain the pressure curve of the pipe pile to be customized;

[0018] (6) Analyze the pressure curve of the pipe pile to be customized. The difference between the soil layer elevation where the final pressure value reaches and the ground elevation is the length of the pipe pile to be customized.

[0019] Furthermore, in step (1), specifically, select multiple representative land sample points in the predetermined construction area for detailed geological exploration, understand the geological structure, soil type, and rock distribution of the construction area and record the geological exploration report. According to the geological exploration report, use BIM technology to draw the three-dimensional geological model and the pipe pile structure model.

[0020] Furthermore, in step (1), create the three-dimensional geological model and the pipe pile structure model through Revit software.

[0021] Furthermore, in step (3), record the pressure value once every 1 m of driving the test pile.

[0022] Furthermore, in step (3), designate at least two test piles in the plots with similar geology.

[0023] Further, in step (5), the linear regression method is adopted to integrate the pressure curve graphs of test pile 1 and test pile 2 and obtain the linear pressure curve.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: By comprehensively applying means such as geological exploration, BIM technology, and data analysis, precise customization of the pipe pile length is realized. This method can not only improve construction efficiency and reduce project risks, but also optimize resource allocation and enhance project quality, and is an indispensable part of modern construction projects.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Under the guidance of the inventive concept of the present invention, a certain construction site adopts the method for precise customization of the pipe pile length of the present invention, which specifically includes the following steps:

[0034] (1) Analyze land samples at fixed points to generate geological exploration reports, draw BIM geological models based on the reports, and establish three-dimensional geological models and pipe pile structure models;

[0035] First, select multiple representative land sample points within the predetermined construction area for detailed geological exploration. Through the analysis of these sample points, accurate geological exploration reports can be generated to understand the geological structure, soil type, rock distribution, etc. of the construction area;

[0036] Based on the geological exploration report, use BIM (Building Information Modeling) technology to draw three-dimensional geological models and pipe pile structure models. These two models will provide basic data for subsequent analysis and calculations. When establishing the models, special attention should be paid to the accuracy and precision of the models to ensure the smooth progress of subsequent steps; When drawing BIM geological models and pipe pile structure models, geographic information systems (GIS) and other related software can be used to assist in completion;

[0037] (2) Determine the rock penetration depth position of the pipe pile model: By analyzing the three-dimensional geological model and the pipe pile structure model, the rock layers that the pipe pile model needs to penetrate and their depth positions can be determined;

[0038] (3) Analyze plots with similar geology in the area. Designate two test piles in different areas, numbered Test Pile 1 and Test Pile 2 respectively, and collect the pressure values of the on-site test piles;

[0039] Select plots with similar geology in the area and designate two test piles on these plots, numbered Test Pile 1 and Test Pile 2 respectively. Then, conduct pressure tests on these two test piles respectively to collect the pressure value data under different rock layers;

[0040] (4) Establish a rectangular coordinate system with the pressure value as X and the thickness of the penetrated rock layer as Y. Draw pressure curves for Test Pile 1 and Test Pile 2 respectively based on the pressure value data collected in step (3), as Figure 1 、 Figure 2 shown;

[0041] (5) As Figure 3 shown, integrate the pressure curves of Test Pile 1 and Test Pile 2 obtained in step (4) and obtain a linear pressure curve as Figure 4 shown; Based on the linear pressure curve, draw a straight line that intersects the linear pressure curve at the X direction with the intersection depth of each rock layer that the to-be-customized pipe pile needs to penetrate as the base point. Connect the intersection points of the line segment corresponding to the rock layer on the linear pressure curve and the straight line of the corresponding rock layer to obtain a pressure curve of the to-be-customized pipe pile as Figure 5 shown;

[0042] (6) Analyze the pressure curve of the to-be-customized pipe pile. The difference between the soil layer elevation reached by the final pressure value and the ground elevation is the length of the to-be-customized pipe pile.

[0043] The pipe pile precise customization method provided by the present invention mainly has the following effects:

[0044] 1) Precise determination of pile length: By analyzing land samples at fixed points, generating geological exploration reports and BIM geological models, the geological conditions of the construction area can be accurately understood, providing reliable data support for determining the pipe pile length.

[0045] Draw the pipe pile structure model and determine the rock penetration depth position to further ensure that the pile length can meet the geological conditions and design requirements.

[0046] 2) Improvement of construction efficiency: Select plots with similar geology in the area for test pile testing, and effective pressure value data can be collected more quickly, shortening the pre-construction preparation time.

[0047] Use BIM technology and pressure curve graphs to determine the pile length, improving the accuracy and efficiency of the analysis process.

[0048] 3) Reduction of project risks: Through detailed land surveys and geological modeling, problems that may be encountered during pipe pile construction, such as rock layer changes and soil bearing capacity, can be predicted more accurately, and corresponding measures can be taken in advance to reduce project risks.

[0049] Draw the pressure curve graph and determine the pressure curve of the to-be-customized pipe pile, which helps to ensure that the pipe pile can withstand sufficient pressure during construction, avoiding pile body damage or construction failure.

[0050] 4) Optimization of resource allocation: Precise determination of the pile length can reduce unnecessary material waste and labor input, reducing project costs.

[0051] Optimize the pipe pile design according to the pressure curve graph, which can ensure that the pile body strength and stiffness meet the requirements, while reducing the pile body weight and volume, facilitating transportation and installation.

[0052] 5) Enhancement of project quality: Precise control of the pile length can ensure that the pipe pile has sufficient bearing capacity and stability when passing through different rock layers, improving the overall quality of the foundation project.

[0053] Through test pile testing and data analysis, the pipe pile design parameters and construction methods can be continuously optimized, enhancing the reliability and durability of the entire project.

[0054] In summary, the above method realizes the precise customization of the pipe pile length by comprehensively applying means such as geological exploration, BIM technology, and data analysis. This method can not only improve the construction efficiency and reduce the project risks, but also optimize the resource allocation and enhance the project quality. It is an indispensable part of modern construction projects.

[0055] Based on the fixed-point analysis of soil samples and the generation of geological exploration reports, professional BIM (Building Information Modeling) software such as Revit is used to create a three-dimensional geological model and a pipe pile structure model. With its powerful three-dimensional modeling ability and rich tool set, Revit software can accurately transform the geological data in the geological exploration report into a three-dimensional visual geological model. At the same time, through parametric design, a pipe pile structure model that meets the design requirements can be quickly created. These two models provide intuitive and accurate data support for subsequent analysis and calculation.

[0056] Analyzing the three-dimensional geological model and the pipe pile structure model can accurately determine the rock layers that the pipe pile model needs to pass through and their depth positions. This is the basis for subsequent calculations and designs, ensuring that the pipe pile can pass through each rock layer safely and stably during actual construction.

[0057] When analyzing plots with similar geology in the area, two test piles are designated - Test Pile 1 and Test Pile 2. During the driving process of these two test piles, the pressure value is recorded every 1 m. Through this method, detailed and accurate pressure value data are collected, which are used for subsequent pressure analysis and calculation.

[0058] Taking the pressure value as the X-axis and the thickness of the rock layer passed through as the Y-axis, a rectangular coordinate system is established. Then, according to the collected pressure value data, pressure curves for Test Pile 1 and Test Pile 2 are respectively plotted in the coordinate system. These curves visually show the change of pressure with the thickness of the rock layer, providing reference information for determining the length of the pipe pile to be customized.

[0059] When integrating the pressure curves of Test Pile 1 and Test Pile 2, the linear regression method is adopted. Based on the existing data points, this method fits the best linear pressure curve through mathematical methods. This curve reflects the overall relationship between pressure and the thickness of the rock layer, providing an important basis for determining the length of the pipe pile to be customized.

[0060] Based on the linear pressure curve, taking the intersection depths of the boundaries of each rock layer that the pipe pile to be customized needs to pass through as the base points, lines intersecting with the linear pressure curve are drawn in the X direction. Then, connecting lines are made with the intersection points of the line segments corresponding to the rock layers on the linear pressure curve and the lines corresponding to the rock layers. Finally, the pressure curve of the pipe pile to be customized is obtained. This curve provides precise guidance for determining the specific pile length.

[0061] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
