Description

Technical Field

[0001] This invention belongs to the field of building technology, specifically relating to an information-based construction method, device, and computer equipment for pile foundation rock-insertion construction. Background Technology

[0002] In construction projects, pile foundations are an important part of the project as load-bearing or maintenance structures. Since the unit price per linear meter of drilling rigs differs greatly between soft soil and hard rock during the pile foundation drilling process, the strata passed through during the pile foundation drilling process and the thickness of each stratum directly affect the cost of pile foundation drilling. In the traditional construction process, drilling subcontractors are relied on to keep records. However, the records kept by subcontractors are often untrue and opaque, which in turn affects internal cost control.

[0003] Furthermore, during the pile foundation drilling process, the traditional technical briefing method usually uses two-dimensional planar design drawings such as plan, elevation, and section to express the process. On the one hand, the number of geological exploration boreholes is limited, and the two-dimensional section drawings are only for reference and cannot accurately record the thickness of each stratum through which each pile is drilled. On the other hand, it cannot intuitively represent the thickness of each soil layer. On-site records are often untrue and inaccurate, which is not conducive to cost control and construction energy efficiency calculation. Summary of the Invention

[0004] The purpose of this application is to propose an information-based construction method for pile foundation drilling into rock, in order to solve the current problem that it is impossible to accurately and intuitively record the thickness of each stratum through which each pile is drilled.

[0005] To address the problems in the existing technology, this application proposes an information-based construction method for pile foundation rock penetration, comprising the following steps:

[0006] Establish a 3D model of a unit-length slice of the pile foundation with coordinate information;

[0007] Obtain the pile location coordinates, drilling depth, and real-time torque or current data of the drilling equipment at the construction site;

[0008] The three-dimensional model is positioned and associated with the on-site pile foundation based on the pile location coordinates.

[0009] The three-dimensional model of the pile foundation is driven to grow longitudinally in real time according to the drilling depth;

[0010] When the torque or current data changes abruptly, a marker point is generated at the depth of the longitudinally growing pile foundation in the three-dimensional model.

[0011] After the pile foundation construction is completed, the marker points of each layer in the three-dimensional model are connected to expand it into a metric conventional plate model to form the interface of each soil layer.

[0012] The thickness of each soil layer is determined based on the interfaces formed by each soil layer and in combination with depth data.

[0013] To address the aforementioned technical problems, this application also provides an information-based construction device for pile foundation rock penetration, the device comprising:

[0014] The data acquisition module is used to acquire the pile location coordinates, drilling depth, real-time torque or current data of the drilling equipment at the construction site.

[0015] The model building module is used to create a 3D model of the pile foundation unit length slice with coordinate information; to establish the positioning association between the 3D model and the on-site pile foundation based on the pile location coordinates; to drive the longitudinal growth of the pile foundation in the 3D model in real time according to the drilling depth; to trigger the generation of marker points at the abrupt change depth of the longitudinally growing pile foundation in the 3D model when the torque or current data changes abruptly; and to connect the marker points of each layer in the 3D model after the pile foundation construction is completed, expanding it into a metric conventional plate model to form the interface of each soil layer; and

[0016] The thickness determination module is used to determine the thickness of each soil layer based on the formed interfaces of each soil layer and in combination with depth data.

[0017] To address the aforementioned technical problems, this application also provides a computer device, including a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the steps of the above-described information-based construction method for pile foundation rock penetration.

[0018] Compared with the prior art, the embodiments of this application have the following main advantages:

[0019] This application maps the monitoring data of the pile foundation during construction into the three-dimensional model of the pile foundation, and obtains the soil interface at the point of change when the current data changes abruptly. Based on the soil interface and the drilling depth, the soil thickness is then calculated. In other words, by combining the mapping of the three-dimensional model of the pile foundation and the real-time monitoring data, the change in soil thickness is fed back in real time, making the calculation of soil thickness more real-time and improving the accuracy of soil thickness determination. Moreover, the entire process does not require manual recording of soil thickness, making the determination of soil thickness more efficient. Attached Figure Description

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0036] Server 105 can be a server that provides various services, such as a backend server that supports the pages displayed on terminal devices 101, 102, and 103.

[0037] It should be noted that the information-based construction method for pile foundation rock penetration provided in this application embodiment is generally executed by server / terminal equipment, and correspondingly, the information-based construction device for pile foundation rock penetration is generally installed in the server / terminal equipment.

[0038] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0039] In the embodiments of this application, such as Figure 2 As shown, Figure 2 This is a flowchart illustrating the information-based construction method for pile foundation rock penetration provided in this application embodiment. The specific implementation of the information-based construction method for pile foundation rock penetration includes:

[0040] Step S201: Establish a three-dimensional model of a unit length slice of the pile foundation with coordinate information.

[0041] In this embodiment of the application, establishing a three-dimensional model of a pile foundation unit length slice with coordinate information includes:

[0042] Use 3D modeling software to read the element information of the pile foundation construction plan;

[0043] Based on the element information in the pile foundation construction plan, determine the absolute coordinates of the pile location for each pile.

[0044] A 3D model of a unit length slice of the pile foundation with absolute coordinates is drawn using 3D modeling software, such as... Figure 3 As shown.

[0045] The steps for determining the absolute coordinates of each pile are as follows: First, locate the circle in the CAD construction plan, determine the circular outline and leader line of the pile foundation through layers, and then read the center coordinates and radius to determine the absolute coordinates of each pile.

[0046] like Figure 3 As shown, the diagram uses retaining piles as an example. Each black dot represents one pile, and each pile represents a unit length. In this embodiment, the pile foundation model is created using Revit, and only a unit length slice of each pile is generated. The unit length slice is determined based on the accuracy of the depth sensor and the allowable pile length deviation specified in the standards. In this embodiment, the initial slice thickness is set to 10cm. The 3D BIM model obtained using this step employs the absolute coordinates of the pile foundation, enabling association with BeiDou pile driving positioning data.

[0047] In this embodiment, the method further includes displaying the 3D model in a lightweight web browser after step S201. This is mainly achieved by displaying the completed 3D model in a lightweight web browser using BIMFACE or other lightweight engines. After display, a component tree list can be automatically generated. The lightweight display does not change the modeled component information.

[0048] Step S202: Obtain the pile location coordinates, drilling depth, and real-time torque or current data of the drilling equipment at the construction site.

[0049] In this embodiment, data is acquired by setting up sensors at the construction site. Specifically, in this embodiment, Beidou positioning sensors, depth sensors, current sensors, and torque sensors are installed on the drilling equipment at the site. The Beidou positioning sensor can locate the coordinates, and the depth sensor can obtain the drilling depth; the current sensor and torque sensor will obtain different current and torque values ​​according to the different changes in drilling torque and current of the drilling equipment in different strata. The Beidou positioning sensor, depth sensor, current sensor, and torque sensor monitor the pile position coordinates, drilling depth, real-time torque, and current data, respectively. The drilling equipment includes rotary drilling rigs, long auger drills, and forward and reverse circulation drills. In one embodiment, an equipment operation terminal can also be set up on site. The equipment operation terminal is used to receive data from various sensors and upload the data to the system database via the network. At the same time, the equipment operation terminal also has the function of initial configuration determination. Initial configuration requires selecting the coordinate system to be used. When downloading the project pile foundation coordinates and starting pile driving, manually clicking "start pile driving" can realize the association between the drilling equipment data and the pile foundation model.

[0050] Step S203: Based on the pile location coordinates, establish the positioning association between the three-dimensional model and the on-site pile foundation.

[0051] In this embodiment, the key to the invention is the association algorithm between the 3D BIM model and the drilling equipment. This embodiment achieves association and driving through a coordinate association algorithm. Specifically, this embodiment mainly uses coordinate projection forward and inverse calculations to determine and associate the physical coordinates obtained by the BeiDou positioning sensor on site with the plane coordinates of the model design, thereby establishing a mapping relationship between the pile foundation model (modeled by the absolute coordinates of the design in BIM) and the construction site. Furthermore, the unique pile code ID in the BIM model is used to bind and associate the equipment data.

[0052] For example, a certain project uses the Web Mercator projection (projection calculation method code EPSG3875) as the map projection method. Assume the spherical latitude and longitude coordinates are... The map's planar coordinates are (E, N), and its projection calculation formula is:

[0053] E=Rλ

[0054]

[0055] In the formula: E represents the east-west coordinate, N represents the north-south coordinate, and the unit is meters; λ represents longitude. The latitude is expressed in radians, and the value of λ ranges from [-π, π]. The value range is [-0.47250627π, 0.47250627π]; R is the radius of the sphere, and the semi-major axis radius of the WGS84 ellipsoid is taken as 6378137.0 meters in the calculation process.

[0056] Specifically, in the application scenario of this embodiment, the steps are as follows:

[0057] First, import the completed 3D model into Revit software. Upon initial loading of the system database, the pile foundation attribute data in the 3D model is automatically extracted and saved, and a unique code ID is generated for each pile.

[0058] Once the on-site sensors and equipment operation terminals are installed, the initial configuration of the equipment terminal parameters is performed, including, for example: positioning settings, coordinate transformation parameter configuration (ellipsoid settings, projection settings, coordinate parameter configuration), sensor settings, and differential settings.

[0059] By connecting the pile foundation model with the equipment operation terminal API, the data of the work area and pile foundation are sent to the equipment operation terminal, and the unique identifier ID of the pile foundation is bound to the construction site.

[0060] The equipment terminal reports real-time monitoring data of the piles under construction (hole position deviation, drilling depth, pile verticality, rotation speed, current value, etc.).

[0061] Step S204: Divide the work area according to the construction organization, and drive the longitudinal growth of the pile foundation in the three-dimensional model in real time according to the drilling depth, such as... Figure 4 As shown.

[0062] In this embodiment, the 3D model is vertically stretched according to the depth obtained by the depth sensor to achieve matching with the drilling depth.

[0063] The work area division algorithm is as follows:

[0064] Partitioning operations are performed in the 3D space of the web-based model. To facilitate partitioning, the perspective projection model first needs to undergo view transformation. The algorithm is based on geometric transformation algorithms in computer graphics. The basic forms of 3D transformations are translation, scaling, rotation, and displacement. However, in actual modeling, it is necessary to handle combinations of several transformations simultaneously. In interactive computer graphics, homogeneous coordinates are commonly used. The homogeneous coordinate system adds a coordinate axis W to the XYZ 3D coordinate system. A point P(x,y,z) in the 3D coordinate system is represented by a quadruple P(x,y,z,w) in the homogeneous coordinate system. The calculation principle of view transformation, and the calculation matrices used, are listed below:

[0065] (1) Translation transformation

[0066] For points in X, Y, Z space, adding a displacement in a specified direction can move them to a new position. The displacement increment is decomposed along the x, y, and z directions, yielding three displacement components dx, dy, and dz. In a homogeneous coordinate system, the translation transformation is represented as the product of a 4×4 matrix and a point vector, i.e.

[0067]

[0068] in It is the homogeneous transformation matrix of the three-dimensional translation transformation.

[0069] (2) Proportional transformation

[0070] Similar to translation transformations, the scaling factor can be decomposed into three components Sx, Sy, and Sz along the x, y, and z directions. Then, points P(x,y,z) and P′(x′,y′,z′) satisfy the following:

[0071]

[0072] in It is a homogeneous matrix under three scaling transformations.

[0073] (3) Rotation transformation

[0074] First, consider the rotation problem around the three axes, and we can obtain the following rotation matrix:

[0075]

[0076] The three-dimensional rotational transformation is a combination of the above rotations around coordinate axes, and its transformation matrix has the following form:

[0077]

[0078] All transformation matrices have inverse transformation forms; the translation transformation is T. -1 =T(-d) x ,-d y ,-d z The scaling transformation is S. -1 =S(1 / s x ,1 / s y ,1 / s z The rotation transformation is R. -1 =R(-θ).

[0079] By transforming the view, the model is set to a parallel projection top view. Then, using the graphics engine's mouse-interactive point selection method, boundary polygons are added, and the set of plotted points becomes the set of partition boundary points. Based on the model's bottom and top elevations, a polygon bounding box is formed for spatial relationship calculations.

[0080] The calculation of spatial relationships between components mainly involves calculating the local coordinates of the center of the pile foundation components in the BIM model, transforming the global coordinates of the overall model, and determining the bounding box to which the component belongs. For example, to obtain the center point coordinates of the pile foundation component, all vertex coordinates of the pile foundation component are picked, and the minimum and maximum values ​​of the x, y, and z coordinates are selected respectively to obtain the minimum and maximum coordinates of a single pile foundation component, determine the spatial range of the component, and then pick the center point. If the coordinates of the model components need to be transformed with the overall coordinate system of the scene, it is also necessary to achieve this through local and global coordinate rotation transformation. In computer graphics, this is mainly achieved by rotating around the three coordinate axes by a certain angle to make the corresponding points of the two coordinate systems coincide. Assuming that the local coordinate system is rotated counterclockwise by angles θ1, θ2, and θ3 around the X-axis, Y-axis, and Z-axis respectively to coincide with the global coordinate system, then the transformation between the point (X, Y, Z) in the local coordinate system and the corresponding point (X′, Y′, Z′) in the global coordinate system is as follows:

[0081]

[0082] For two spatial coordinate systems that undergo translation transformation, first solve for the offsets ΔX, ΔY, and ΔZ. Then, the transformation between a point (X,Y,Z) in the local coordinate system and the corresponding point (X′,Y′,Z′) in the global coordinate system is as follows:

[0083]

[0084] Considering the above spatial transformation scenarios, the final solution can be achieved through matrix transformation:

[0085]

[0086] Complete the transformation from a point in the local coordinate system to the global coordinate system.

[0087] After the component coordinates are consistent, determine whether the component's center point belongs to a certain bounding box to determine the corresponding partition.

[0088] The graphical interactive dragging of boundary points is used for secondary editing of partition boundary points. It adopts the rubber band technique of computer graphics and is implemented directly using the mouse message response function of the graphics engine.

[0089] Boundary polygons can have their attributes such as color, transparency, and name modified; once saved, they can be used as a partition. For example... Figure 5 As shown, this embodiment is divided into area A-1, area A-2 and area B.

[0090] Digital model driven algorithm description: The algorithm judges the displacement of the pile head by using real-time depth data reported by the device operation terminal, so as to achieve the dynamic effect of data-driven drill bit status. The process data upload device interface is as follows, through which information such as time, depth, and sequence number are uploaded.

[0091] Assume that the sequence number of the current depth data is i, and the corresponding depth value is hi; the previous sequence number is i - 1, and the corresponding depth value is hi - 1;

[0092] If hi - 1 < hi, it is judged as the downhole drilling state; if hi - 1 > hi, it is judged as the uphole drilling state; calculate the depth change value, estimate the moving displacement s of the drill bit, and based on the time t corresponding to the two sets of data before and after, the downhole / uphole drilling rate can be calculated.

[0093] Step 205, generate a marker point at the mutation depth position of the pile foundation with longitudinal growth in the three-dimensional model when the torque or current data mutates.

[0094] ... In this embodiment, the generated marker points can be represented by a sphere family, as Figure 6 shown. Among them, since the current and torque sensors have different current and torque values in each formation, it is determined to enter a new soil layer through the mutation of the current value and torque value. The mutation here does not refer to the sudden increase or decrease of a single point. The mutation of the current value is judged through an algorithm in terms of time and depth. For example, if the mutation value remains stable within a certain time or a certain drilling depth after the mutation, it is determined that the mutation is effective, that is, a sphere model is triggered and generated at the corresponding position in the model.

[0095] The specific algorithm for each soil layer to sense and trigger the calibration sphere family is as follows:

[0096] The soil layer sensing algorithm is as follows:

[0097] Data source: First, after the three-dimensional model is uploaded, the system automatically obtains the pile foundation information (component ID, pile number, designed pile top elevation, designed reinforcement cage length, pile position coordinates, pile body concrete strength, pile diameter, pile length, bottom elevation, top elevation, pile position coordinate deviation, etc.) in the three-dimensional model according to the agreed hierarchical structure and saves it to the system database. Then, connect to the on-site equipment operation terminal. When the equipment operation terminal works, it will report data such as depth, rotation speed, verticality deviation, pile body hole position deviation, current, perfusion volume, etc. to the system according to different equipment types, and the system will automatically save the relevant data to the system database. Finally, the system automatically obtains the current and torque time series data and performs trigger calibration according to the following steps:

[0098] Obtain the current time series data of this pile from the system database and perform filtering transformation to eliminate gross error points;

[0099] Judge according to a fast inflection point detection algorithm based on time series to obtain the moment corresponding to the turning change of the current value, and obtain the drilling depth h1 at this moment from the database;

[0100] Retrieve the final drilling depth h2 corresponding to the piling end time from the database and perform judgment and calculation;

[0101] The depth of entry into different soil layers is h = h2 - h1 (the time-series current value satisfies h1 ≤ h2); if h = 0, it is determined that the rock has just been entered; if h > 0, the value is stored as a reference value for entering a new soil layer.

[0102] Step S206: After the pile foundation construction is completed, connect the marker points of each layer in the 3D model to expand it into a metric conventional plate model, forming the interfaces of each soil layer, such as... Figure 7 As shown.

[0103] Specifically, the sphere model is built-in. The external components are spheres with the same diameter as the piles. When the current and torque values ​​change abruptly, they are generated from top to bottom according to the default color. After completion, the sphere models of the same color for each pile are connected and connected with metric conventional plate models to generate interface models of different strata.

[0104] Step S207: Determine the thickness of each soil layer based on the interface formed by each soil layer and the values ​​returned by the depth sensor.

[0105] In this embodiment, each pile records the percentage of the current drilling depth relative to the designed depth each time there is a sudden change in current, and uploads the data to a database for storage.

[0106] It may also include step S208, exporting an Excel table containing drilling efficiency and cost information for each rock stratum in the pile foundation project.

[0107] In this step, the drilling thickness of the drilling rig in each stratum can be obtained by statistically analyzing the stratum boundaries. By inputting the drilling cost per linear meter of the drilling rig in each stratum, the comprehensive unit price and pile construction cost of the entire pile can be obtained, which facilitates cost calculation and efficiency acquisition, thereby achieving cost control and reasonable allocation of machinery.

[0108] Specifically, the web page has a built-in table containing the names of the strata corresponding to the geological survey of this project and the engineering cost per linear meter of drilling into each stratum. In addition, information on each completed pile can be automatically written in, and the percentage of drilling depth to design depth corresponding to each current change for each completed pile can be exported.

[0109] Table 1. Statistics on Pile Foundation Completion Information

[0110]

[0111] Based on the data obtained from the table above, the comprehensive unit price per linear meter of the pile can be calculated as follows:

[0112] W (Comprehensive Unit Price) = a*w1 + (ba)*w2 + (cb)*w3 + (dc)*w4

[0113] The total cost of drilling a single pile is W*L; by taking the start time, end time and corresponding depth of each soil layer, the drilling efficiency of the pile driver in that soil layer can be obtained. For example, the drilling efficiency in a coarse sand layer is G2 = (ba)*L / (t2-t1); to calculate the drilling efficiency over the entire pile length, the arithmetic average of each stratum can be obtained.

[0114] like Figure 8 As shown, this embodiment also provides an information-based construction device for pile foundation rock penetration, including:

[0115] Data acquisition module 801 is used to acquire the pile position coordinates, drilling depth, real-time torque or current data of the drilling equipment at the construction site;

[0116] The model building module 802 is used to establish a three-dimensional model of a unit length slice of pile foundation with coordinate information; to realize the positioning association between the three-dimensional model and the on-site pile foundation according to the pile position coordinates; to drive the longitudinal growth of the pile foundation in the three-dimensional model in real time according to the drilling depth; to trigger the generation of marker points at the abrupt change depth of the longitudinally growing pile foundation in the three-dimensional model when the torque or current data changes abruptly; and to connect the marker points of each layer in the three-dimensional model after the pile foundation construction is completed, expanding it into a metric conventional plate model to form the interface of each soil layer.

[0117] The thickness determination module 803 is used to determine the thickness of each soil layer based on the formed interfaces of each soil layer and in combination with depth data.

[0118] The information-based construction device for pile foundation rock penetration also includes a calculation module 804. The calculation module 804 is used to calculate the drilling thickness of the drilling rig in each stratum, which can be obtained through the stratum boundary, and to obtain the comprehensive unit price and pile construction cost of the entire pile based on the input drilling cost per linear meter of the drilling rig in each stratum, and to calculate the drilling efficiency of each bottom layer.

[0119] Regarding the information-based construction device for pile foundation rock penetration in the above embodiments, the specific methods of each module's operation have been described in detail in the embodiments of the relevant method, and will not be elaborated here.

[0120] To address the aforementioned technical problems, embodiments of this application also provide a computer device. Please refer to [link / reference needed]. Figure 9 , Figure 9 This is a basic structural block diagram of the computer device in this embodiment.
