Description

Technical Field

[0001] The present invention relates to the technical field of intelligent positioning and pouring integration for pile foundation reinforcement cage construction, and in particular to an intelligent positioning and pouring integration platform for pile foundation reinforcement cage construction. Background Art

[0002] In the existing pile foundation construction, the position of the steel cage is manually adjusted based on the experience of the construction workers. This manual positioning method is not only inefficient, but also easily interfered by human factors. It is difficult to ensure the verticality and plane position accuracy of the steel cage in the pile hole. At the same time, in the concrete pouring process, it is difficult to flexibly adjust the concrete pouring parameters according to the actual state of the steel cage due to the inability to grasp the dynamic position changes of the steel cage in real time and accurately. Therefore, in order to ensure the quality of pile foundation construction, it is necessary to develop an integrated platform for intelligent positioning and pouring of pile foundation steel cage construction.

[0003] For example, the Chinese patent publication number CN110130347B discloses an intelligent positioning and guiding device, method, and engineering management method for pile foundation construction. The intelligent positioning and guiding device for pile foundation construction includes an outer casing, an inner casing, a position adjustment mechanism, and a positioning mechanism. The position data information of the inner casing is obtained by the positioning mechanism, and the adjustment action of the position adjustment mechanism is controlled by the position data information to achieve accurate positioning of the pile foundation guide and positioning in the steel cage hole, improve the drilling accuracy of cast-in-place pile construction and the vertical accuracy of steel cage hoisting and lowering, solve the safety hazards of conventional cast-in-place pile construction caused by uneven hardness of the stratum soil, non-vertical pile body, and pile body deflection and uneven force caused by inaccurate lowering of the steel cage, ensure construction quality, and improve management efficiency.

[0004] For example, the Chinese patent publication number CN118774110A discloses a method for constructing a steel pipe column by inserting first, including: laying out lines for positioning, and burying casing. After positioning, determine that the pile hole is formed, and use a bottom expansion drill to expand the hole. Set up a steel cage and adjust the position of the steel cage. Lower the steel cage into the pile hole. Lift the vertical adjustment machine to the top of the pile hole, move the vertical adjustment machine to the measurement position, and keep the vertical adjustment machine horizontal. Lift the steel pipe column, lift the steel pipe column into the vertical adjustment machine, and adjust the horizontal elevation and verticality of the steel pipe column through the control system. Bury a conduit in the pile hole and pour the pile foundation concrete. Replace the concrete and continue pouring in the steel pipe column. The present application has the effect of avoiding the installation risk that the steel pipe column cannot be inserted into the column foundation due to the difficulty in controlling the solidification time of the super slow setting concrete.

[0005] The following problems still exist in the prior art: 1. Whether the placement position of the steel cage is accurate is not comprehensively evaluated from two aspects: the vertical placement condition and the placement offset condition after the steel cage is placed in the corresponding pile foundation, which reduces the comprehensiveness and accuracy of the evaluation of whether the placement position of the steel cage is accurate, and affects the construction quality of the subsequent concrete pouring.

[0006] 2. The problems in the pouring process were not confirmed by combining the floating of the steel cage and the overall verticality during the concrete pouring process. At the same time, no specific concrete pouring adjustments were made based on the specific problems, resulting in damage to the structural integrity, thereby affecting the integrity and durability of the pile foundation. If these problems in the pouring process are not discovered and resolved in a timely manner, the pile foundation quality may be unqualified and rework may be required, affecting the construction progress and increasing the construction cost.

[0007] 3. When there is a problem with the overall verticality of the steel cage during the concrete pouring process, the adjustment position of the concrete pouring conduit is not classified and discussed according to the overall offset of the steel cage, and the position of the steel cage cannot be accurately corrected, which reduces the correction effect of the offset of the steel cage. Summary of the invention

[0008] In view of this, in order to solve the problems raised in the above background technology, an integrated platform for intelligent positioning and pouring of pile foundation reinforcement cage construction is proposed.

[0009] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides an integrated platform for intelligent positioning and pouring of pile foundation steel cage construction, including: a steel cage placement information acquisition module, which is used to construct a three-dimensional model of the target steel cage in the target construction site after it is placed in the corresponding pile foundation, and obtain the placement information of the target steel cage after it is placed in the corresponding pile foundation.

[0010] The placement position accuracy assessment module is used to assess whether the placement position of the target steel cage is accurate before concrete pouring. If it is not accurate, the placement position of the target steel cage is repositioned. If it is accurate, the vertical floating trend analysis module is executed.

[0011] The vertical floating trend analysis module is used to randomly select several points on the target steel cage as monitoring points and obtain the corresponding data of each monitoring point on the target steel cage in each concrete pouring stage. Axis coordinate values ​​are used to analyze the vertical floating trend index of the target steel cage in each concrete pouring stage.

[0012] The overall verticality analysis module is used to select measurement points on the top edge of the target steel cage, and record the points on the bottom edge corresponding to the measurement points on the top edge as the corresponding points of the measurement points, obtain the position coordinate values ​​of the corresponding points of the measurement points on the top edge and the measurement points on the bottom edge of the target steel cage in each concrete pouring stage, and analyze the overall verticality of the target steel cage in each concrete pouring stage.

[0013] The concrete pouring adjustment module is used to confirm the pouring adjustment type corresponding to the target steel cage in each concrete pouring stage, extract the concrete pouring speed set in each concrete pouring stage, and make pouring adjustments in each concrete pouring stage according to the pouring adjustment type.

[0014] Database, used to store the corresponding information of each monitoring point after the placement of the target reinforcement cage is accurate before concrete pouring The standard coordinate value of the axis stores the concrete pouring speed required to reduce the vertical floating trend of the unit.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention comprehensively evaluates whether the placement position of the steel cage is accurate from two aspects: the vertical placement condition and the placement offset condition after the steel cage is placed in the corresponding pile foundation, thereby improving the comprehensiveness and accuracy of the evaluation of whether the placement position of the steel cage is accurate, and avoiding affecting the construction quality of the subsequent concrete pouring.

[0016] (2) The present invention determines the pouring adjustment type by combining the floating condition of the steel cage and the overall verticality during the concrete pouring process, and makes specific concrete pouring adjustments according to the pouring adjustment type, thereby avoiding damage to the structural integrity, thereby avoiding affecting the integrity and durability of the pile foundation. At the same time, these problems in the pouring process are discovered and solved in a timely manner, thereby improving the quality of the pile foundation, avoiding affecting the construction progress, and reducing the construction cost.

[0017] (3) When the casting adjustment type corresponding to the target steel cage is steel cage tilt, the present invention classifies and discusses the adjustment position of the concrete casting conduit according to the overall offset of the target steel cage, thereby helping to accurately correct the position of the steel cage and improving the correction effect of the steel cage offset.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 As shown, the present invention provides an integrated platform for intelligent positioning and pouring of pile foundation steel cage construction, including: a steel cage placement information acquisition module, a placement position accuracy assessment module, a vertical floating trend analysis module, an overall verticality analysis module, a concrete pouring adjustment module and a database.

[0025] The steel cage placement information acquisition module is connected to the placement position accuracy assessment module, the placement position accuracy assessment module is connected to the vertical floating trend analysis module, the vertical floating trend analysis module and the overall verticality analysis module are both connected to the concrete pouring adjustment module, and the vertical floating trend analysis module and the concrete pouring adjustment module are both connected to the database.

[0026] The reinforcement cage placement information acquisition module is used to construct a three-dimensional model of the target reinforcement cage in the target construction site after it is placed in the corresponding pile foundation, and to obtain the placement information of the target reinforcement cage after it is placed in the corresponding pile foundation.

[0027] It should be noted that the three-dimensional model of the target steel cage after being placed in the corresponding pile foundation is constructed in the following way: the target steel cage in the target construction site is scanned by a drone to obtain an image of the target steel cage after being placed in the corresponding pile foundation, and the image of the target steel cage after being placed in the corresponding pile foundation is imported into the modeling software to automatically generate a three-dimensional model of the target steel cage after being placed in the corresponding pile foundation.

[0028] In a specific embodiment of the present invention, the placement information includes the center point position, the coordinate value of the center point position of the bottom plane, and the coordinate values ​​of the positions of the sampling points on the edge wall of the bottom of the pile foundation.

[0029] The placement position accuracy assessment module is used to assess whether the placement position of the target steel cage is accurate before concrete pouring. If it is not accurate, the placement position of the target steel cage is repositioned. If it is accurate, the vertical floating trend analysis module is executed.

[0030] In a specific embodiment of the present invention, the specific process of evaluating whether the placement position of the target steel cage before concrete pouring is accurate is as follows: A1, extracting the center point position, the bottom plane center point position coordinate value and the position coordinate value of each sampling point on the bottom edge wall of the pile foundation from the placement information after the target steel cage is placed in the corresponding pile foundation, and calculating the placement verticality of the target steel cage after being placed in the corresponding pile foundation based on the above information. and placement offset .

[0031] In a specific embodiment of the present invention, the specific process of calculating the placement verticality of the target steel cage after being placed in the corresponding pile foundation is as follows: B1, taking the center point position of the target steel cage after being placed in the corresponding pile foundation as the base point, and taking the placement direction of the target steel cage as the reference direction to construct a center line, obtaining the angle between the center line of the target steel cage and the placement plane, and recording it as the placement deflection angle, thereby obtaining the placement deflection angle of the target steel cage, and recording it as .

[0032] B2. Calculate the verticality of the target reinforcement cage after it is placed in the corresponding pile foundation , ,in, Indicates the installation deflection angle of the set reference.

[0033] See also Figure 3 As shown, in a specific embodiment of the present invention, the specific process of calculating the placement offset of the target steel cage after it is placed in the corresponding pile foundation is as follows: C1, the position coordinate value of the center point of the bottom plane after the target steel cage is placed in the corresponding pile foundation and the position coordinate value of each sampling point on the edge wall of the bottom of the pile foundation are recorded as and ,in, Indicates the number of the sampling point. .

[0034] C2. Calculate the distance between the center point of the bottom plane of the target steel cage after it is placed in the corresponding pile foundation and each sampling point on the edge wall of the bottom of the pile foundation , .

[0035] C3. Calculate the placement offset of the target reinforcement cage after it is placed in the corresponding pile foundation , ,in, It indicates the distance between the center point of the bottom plane of the target steel cage after it is placed in the corresponding pile foundation and the first The distance between the sampling points, Indicates the distance deviation of the set reference. Indicates the number of sampling points.

[0036] A2. Calculate the placement accuracy of the target reinforcement cage after it is placed in the corresponding pile foundation , ,in, and They represent the weights of the placement accuracy assessment corresponding to the set placement verticality and placement offset, respectively. .

[0037] In a specific embodiment of the present invention, The setting value of is 0.5. The setting value is 0.5, which is very critical from the perspective of overall structural safety and construction quality. In actual construction, it is usually necessary to strictly control the placement verticality and placement offset at the same time, and formulate corresponding allowable deviation standards to ensure the accuracy of the placement position of the steel cage, and to ensure the safety and normal use of the pile foundation and even the entire structure.

[0038] See also Figure 2 As shown, A3, the placement position accuracy of the target steel cage after being placed in the corresponding pile foundation is compared with the placement position accuracy of the set reference. If the placement position accuracy of the target steel cage after being placed in the corresponding pile foundation is greater than or equal to the placement position accuracy of the set reference, it indicates that the placement position of the target steel cage before concrete pouring is accurate; otherwise, it indicates that the placement position of the target steel cage before concrete pouring is inaccurate.

[0039] It should be noted that the method of repositioning the placement position of the target steel cage is as follows: when the monitoring system finds that the placement position of the target steel cage is offset, the intelligent control system will issue a command to start the winch to assist in adjusting the placement position of the target steel cage, and coordinate and control the retraction and release speed of the winches at different positions. For example, when the target steel cage needs to move in a certain direction, the winch in that direction appropriately loosens the steel cable, while the winch in the opposite direction tightens the steel cable, thereby guiding the steel cage to move to the correct position in the plane. When the monitoring system finds that the placement of the target steel cage is not vertical, the intelligent control system will control the hydraulic legs of the platform to assist in adjusting the placement verticality of the target steel cage. For example, when the target steel cage tilts to one side, the hydraulic legs close to the tilted side will extend, while the hydraulic legs on the other side will shorten, and the verticality of the target steel cage will be corrected by changing the tilt angle of the platform.

[0040] The embodiment of the present invention comprehensively evaluates whether the placement position of the steel cage is accurate from two aspects: the vertical placement condition and the placement offset condition after the steel cage is placed in the corresponding pile foundation, thereby improving the comprehensiveness and accuracy of the evaluation of whether the placement position of the steel cage is accurate, and avoiding affecting the construction quality of the subsequent concrete pouring.

[0041] The vertical floating trend analysis module is used to randomly select several points on the target steel cage as monitoring points, and obtain the corresponding data of each monitoring point on the target steel cage in each concrete pouring stage. Axis coordinate values ​​are used to analyze the vertical floating trend index of the target steel cage in each concrete pouring stage.

[0042] It should be noted that the corresponding monitoring points on the target steel cage in each concrete pouring stage The axis coordinate values ​​are directly obtained from the three-dimensional model after the target reinforcement cage is placed in the corresponding pile foundation.

[0043] In a specific embodiment of the present invention, the specific process of analyzing the vertical floating trend index of the target steel cage in each concrete pouring stage is as follows: D1, the corresponding vertical floating trend index of each monitoring point on the target steel cage in each concrete pouring stage is calculated. The axis coordinate value is recorded as ,in, The number indicating the concrete pouring stage. , Indicates the number of the monitoring point. .

[0044] D2. Extract the placement position of the target steel cage before concrete pouring from the database and the corresponding position of each monitoring point The standard coordinate value of the axis is recorded as .

[0046] D4. Calculate the vertical floating trend index of the target steel cage in each concrete pouring stage , ,in, Indicates the vertical floating value allowed. Indicates the number of monitoring points.

[0047] It should be noted that the set allowable vertical buoyancy value is stipulated in the industry standard for pile foundation reinforcement cage construction.

[0048] The overall verticality analysis module is used to select measurement points on the top edge of the target steel cage, and record the points on the bottom edge corresponding to the measurement points on the top edge as the corresponding points of the measurement points, obtain the position coordinate values ​​of the corresponding points of the measurement points on the top edge and the measurement points on the bottom edge of the target steel cage in each concrete pouring stage, and analyze the overall verticality of the target steel cage in each concrete pouring stage.

[0049] It should be noted that the position coordinate values ​​of the corresponding points of the measuring points on the top edge and the bottom edge of the target steel cage in each concrete pouring stage are directly obtained from the three-dimensional model after the target steel cage is placed in the corresponding pile foundation.

[0050] In a specific embodiment of the present invention, the specific process of analyzing the overall verticality of the target steel cage in each concrete pouring stage is as follows: E1, the position coordinate values ​​of the corresponding points of the measuring points on the top edge and the bottom edge of the target steel cage in each concrete pouring stage are recorded as and .

[0051] E2. Calculate the coordinate difference of the target reinforcement cage in the X-axis direction in each concrete pouring stage , coordinate difference in the Y-axis direction The coordinate difference with the Z axis direction ,in, , and .

[0052] E3. Calculate the inclination angle of the target steel cage on the XZ plane in each concrete pouring stage , .

[0053] It should be noted that in the XZ plane, assuming that the target steel cage is tilted in this plane, the tilt angle is calculated according to the trigonometric function relationship. A right triangle can be constructed, where is a right-angled side (opposite side) of a right triangle, is the other right-angle side (adjacent side). According to the definition of the tangent function, ,but , this angle represents the inclination of the steel cage relative to the vertical direction in the XZ plane.

[0054] E4. Calculate the inclination angle of the target steel cage on the YZ plane in each concrete pouring stage , .

[0055] It should be noted that, in the YZ plane, following the same method, ,but , this angle represents the inclination of the steel cage relative to the vertical direction in the YZ plane.

[0056] E5. Calculate the overall verticality of the target reinforcement cage in each concrete pouring stage , ,in, Indicates the allowed tilt modulus value. Represents a natural constant.

[0057] It should be noted that the inclination of the target steel cage is calculated based on the coordinate difference of the corresponding points at the top and bottom. For example, the coordinate difference of the two points in the horizontal and vertical directions is calculated, the inclination angle is calculated through trigonometric functions, and finally the inclination is combined to evaluate the overall verticality of the target steel cage. This method has high accuracy and can meet the requirements of most projects.

[0058] The concrete pouring adjustment module is used to confirm the pouring adjustment type corresponding to the target steel cage in each concrete pouring stage, extract the concrete pouring speed set in each concrete pouring stage, and perform pouring adjustment in each concrete pouring stage according to the pouring adjustment type.

[0059] It should be noted that the concrete pouring speed set in each concrete pouring stage is extracted from the concrete pouring control panel of the target construction site.

[0060] In a specific embodiment of the present invention, the specific method of confirming the pouring adjustment type corresponding to the target steel cage in each concrete pouring stage is: constructing a pouring adjustment type evaluation model corresponding to the target steel cage in each concrete pouring stage, and outputting the pouring adjustment type, wherein the pouring adjustment type evaluation model is expressed as: ,in, and Respectively represent the evaluation conditions of each pouring adjustment type, express and , express and , express and ,in, and They respectively represent the vertical upward trend index and overall verticality of the set reference.

[0061] In a specific embodiment of the present invention, the specific process of performing pouring adjustment in each concrete pouring stage according to the pouring adjustment type is as follows: F1. If the pouring adjustment type corresponding to the target steel cage in a certain concrete pouring stage is steel cage floating, the concrete pouring stage is recorded as the floating adjustment stage, and the vertical floating trend index of the target steel cage in the floating adjustment stage is extracted and recorded as , extract the concrete pouring speed set in the floating adjustment stage and record it as , extract the concrete pouring speed required to reduce the unit vertical floating trend from the database and record it as , so the appropriate concrete pouring speed in the floating adjustment stage is obtained , .

[0062] F2. If the pouring adjustment type corresponding to the target steel cage in a certain concrete pouring stage is steel cage tilting, the concrete pouring stage is recorded as the target pouring stage, and the position of the concrete pouring conduit in the target pouring stage is adjusted.

[0063] In a specific embodiment of the present invention, the specific process of adjusting the position of the concrete pouring conduit in the target pouring stage is as follows: G1, extracting the coordinate difference of the target steel cage in the X-axis direction in the target pouring stage The difference between the coordinates in the Y-axis direction .

[0064] G2, when and , indicating that the offset direction of the target steel cage is in the positive direction of the X axis, then move the concrete pouring conduit to the negative direction of the X axis. .

[0065] G3. When and , indicating that the offset direction of the target steel cage is in the negative direction of the X axis, then move the concrete pouring conduit to the positive direction of the X axis. .

[0066] G4. When and , indicating that the offset direction of the target steel cage is in the positive direction of the Y axis, then move the concrete pouring conduit to the negative direction of the Y axis. .

[0067] G5. When and , indicating that the offset direction of the target steel cage is in the negative direction of the Y axis, then move the concrete pouring conduit to the positive direction of the Y axis. .

[0068] G6. When and , indicating that the offset direction of the target steel cage is in the first quadrant of the XY plane, then move the concrete pouring conduit to the negative direction of the X axis. , move in the negative direction of the Y axis .

[0069] It should be noted that when the target steel cage is offset to the first quadrant of the XY plane (i.e., the positive direction of the X-axis and the positive direction of the Y-axis), during the concrete pouring process, the concrete pouring conduit outlet should be moved to the third quadrant (negative direction of the X-axis and the negative direction of the Y-axis), and the moving distance needs to be determined according to the offset of the target steel cage. For example, if the target steel cage is offset by 10 cm in the X direction and 8 cm in the Y direction, the concrete pouring conduit outlet can be first moved 10 cm in the negative direction of the X axis and 8 cm in the negative direction of the Y axis. This is done to utilize the reaction force generated by the concrete flowing out of the conduit to the third quadrant on the steel cage, and gradually correct the offset of the steel cage. The principles involved below are similar and will not be repeated here.

[0070] G7, when and , indicating that the offset direction of the target steel cage is in the fourth quadrant of the XY plane, then move the concrete pouring conduit to the negative direction of the X axis. , move in the positive direction of the Y axis .

[0071] G8, when and , indicating that the offset direction of the target steel cage is in the second quadrant of the XY plane, then move the concrete pouring conduit toward the positive direction of the X axis. , move in the negative direction of the Y axis .

[0072] G9, when and , indicating that the offset direction of the target steel cage is in the third quadrant of the XY plane, then move the concrete pouring conduit toward the positive direction of the X axis. , move in the positive direction of the Y axis .

[0073] The embodiment of the present invention classifies and discusses the adjustment position of the concrete pouring conduit according to the overall offset of the target steel cage when the pouring adjustment type corresponding to the target steel cage is steel cage tilt, thereby helping to accurately correct the position of the steel cage and improving the correction effect of the steel cage offset.

[0074] F3. If the pouring adjustment type corresponding to the target steel cage in a certain concrete pouring stage is comprehensive adjustment of the steel cage, the concrete pouring stage is recorded as a comprehensive adjustment stage, and concrete pouring adjustment is performed on the comprehensive adjustment stage.

[0075] It should be noted that the method of adjusting the concrete pouring in the comprehensive adjustment stage is: to obtain the appropriate concrete pouring speed in the comprehensive adjustment stage in the same way as the analysis method of the appropriate concrete pouring speed in the floating adjustment stage, and to obtain the concrete pouring conduit position adjustment in the comprehensive adjustment stage in the same way as the analysis method of the concrete pouring conduit position adjustment in the target pouring stage.

[0076] The embodiment of the present invention confirms the pouring adjustment type by combining the floating condition of the steel cage and the overall verticality during the concrete pouring process, and makes specific concrete pouring adjustments according to the pouring adjustment type to avoid damage to the structural integrity, thereby avoiding affecting the integrity and durability of the pile foundation. At the same time, these problems in the pouring process are discovered and resolved in a timely manner, thereby improving the quality of the pile foundation, avoiding affecting the construction progress, and reducing the construction cost.

[0077] The database is used to store the corresponding positions of the target steel cages before concrete pouring. The standard coordinate value of the axis stores the concrete pouring speed required to reduce the vertical floating trend of the unit. The data sources in the database of this embodiment are shown in Table 1 below.
