Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, specifically to an adaptive correction method and device for jacking bridge structures. Background Technology

[0002] The multi-point jacking construction technique is often used for large and long bridges with complex vertical curves at the bottom of the beams. During construction, if the jacking equipment is installed at an inaccurate position, or if the friction between the bottom of the beam and the jacking sliding surface is inconsistent, resulting in relative sliding, or if the jacking forces on both sides of the structure are different in magnitude or act asynchronously, lateral displacement of the beam will occur. Severe lateral displacement will not only affect the assembly accuracy of subsequent beam segments, but may also cause the original support positions to deviate, leading to local yielding or even the risk of overturning. Therefore, monitoring lateral displacement during bridge jacking is particularly important.

[0003] Traditional monitoring methods include the marking line method or the observation point method, which collects the coordinates of multiple points on the pushed component through multiple measuring points to determine the offset of the pushed component.

[0004] However, for large and long bridges, the existing technology of marking the entire length of the bridge or setting up observation points at each temporary jacking pier is cumbersome, affects the construction progress, and has high labor costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an adaptive correction method and device for jacking bridge structures. This method solves the problems of existing technologies for large and long bridges, where marking continuous lines or setting up observation points at each jacking temporary pier is cumbersome, affects construction progress, and incurs high labor costs.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] On the one hand, the present invention provides an adaptive correction method for a jacking bridge structure, comprising the following steps:

[0008] Obtain the real-time planar coordinates of both ends of the longitudinal line of the bridge structure during the jacking process;

[0009] Based on the initial plane coordinates and real-time plane coordinates at both ends of the longitudinal line of the bridge structure and the longitudinal bridge coordinates of the transverse jacking equipment, the lateral deviation of the bridge structure at the transverse jacking equipment is determined.

[0010] The offset of the bridge structure is corrected based on the lateral deviation of the bridge structure at the lateral jacking equipment.

[0011] In some alternative solutions, determining the lateral offset of the bridge structure at the transverse jacking device based on the initial plane coordinates and real-time plane coordinates at both ends of the longitudinal line of the bridge structure and the longitudinal bridge coordinates of the transverse jacking device includes:

[0012] Based on the initial and real-time plane coordinates of both ends of the longitudinal line of the bridge structure, determine the lateral offset at both ends of the longitudinal line of the bridge structure.

[0013] The lateral offset at both ends of the longitudinal line of the bridge structure and the longitudinal coordinates of the lateral jacking equipment are used to determine the lateral offset of the bridge structure at the lateral jacking equipment.

[0014] In some alternative solutions, according to the formula Δy1=Y1-Y 01 and Δy2=Y2-Y 02 Determine the lateral offset at both ends of the longitudinal line of the bridge structure, where Y1 is the real-time lateral coordinate of the front end of the bridge structure, and Y... 01 Y is the initial lateral coordinate of the front end of the bridge structure, Δy1 is the lateral offset of the front end of the bridge structure, and Y2 is the real-time lateral coordinate of the rear end of the bridge structure. 02 Let y1 be the initial lateral coordinate of the tail end of the bridge structure, and Δy2 be the lateral offset of the tail end of the bridge structure.

[0015] In some alternative solutions, according to the formula Determine the lateral displacement Δy of the bridge structure at the i-th lateral jacking device. Di X1 is the real-time longitudinal coordinate of the front end of the bridge structure, and X2 is the real-time longitudinal coordinate of the rear end of the bridge structure. Di Let be the longitudinal coordinate of the i-th lateral jacking device.

[0016] In some alternative schemes, when correcting the offset of the bridge structure based on the lateral deviation of the bridge structure at the lateral jacking device, the offset correction step of the bridge structure is performed when the lateral deviation at any lateral jacking device reaches the allowable lateral deviation of the beam.

[0017] In some alternative schemes, the permissible lateral deviation of the beam is the limit of the permissible deviation specified in the code or the permissible correction capability value of the jacking equipment.

[0018] In some alternative solutions, when correcting the offset of the bridge structure, the correction is stopped if the lateral offset at all lateral jacking devices is less than or equal to the allowable error of the bridge structure.

[0019] On the other hand, the present invention also provides an adaptive correction device for a jacking bridge structure, used to execute the adaptive correction method for a jacking bridge structure described in any of the above claims, comprising:

[0020] Two coordinate monitoring units are installed at both ends of the longitudinal line of the bridge structure to obtain the real-time planar coordinates of both ends of the longitudinal line of the bridge structure during the jacking process.

[0021] Multiple lateral jacking devices are installed on temporary supports along the longitudinal direction of the bridge.

[0022] The control module is used to determine the lateral offset of the bridge structure at the lateral jacking device based on the initial plane coordinates at both ends of the longitudinal line of the bridge structure, the real-time plane coordinates, and the longitudinal bridge coordinates of the lateral jacking device, and to control the lateral jacking device to correct the offset of the bridge structure based on the lateral offset of the bridge structure at the lateral jacking device.

[0023] In some alternative solutions, the lateral jacking device includes two lateral jacking units, which are respectively installed on both sides of the bridge structure in the lateral direction.

[0024] In some alternative solutions, the coordinate monitoring unit uses a wireless total station.

[0025] Compared with existing technologies, the advantages of this invention are as follows: This adaptive correction method and device for jacking bridge structures optimizes the arrangement of measuring points during the jacking process. Only one coordinate monitoring unit needs to be set up at each end of the longitudinal line of the bridge structure to obtain the offset of the bridge structure at the location of each lateral jacking device. The lateral jacking devices can then be used to correct the bridge structure's deviation during the longitudinal jacking process, simplifying the setting of monitoring points, reducing costs, and improving construction efficiency. Combined with a control system, the real-time planar coordinates of both ends of the longitudinal line of the bridge structure are automatically collected during jacking, the offset of the bridge structure is calculated, and the jacking of the lateral jacking devices is automatically controlled, enabling adaptive correction of the bridge structure.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the measuring point location arrangement for the adaptive correction method of the jacking bridge structure in an embodiment of the present invention; Figure 2 This is a flowchart of the adaptive correction method for the jacking bridge structure in an embodiment of the present invention. Figure 1 and 2 As shown, on the one hand, the present invention provides an adaptive correction method for a jacking bridge structure, comprising the following steps:

[0033] In this example, the bridge structure includes a main beam 1 and a guide beam 2, and the bridge structure moves along the bridge direction on multiple temporary piers 3 spaced apart along the bridge direction.

[0034] S0: First, arrange the coordinate monitoring unit positions: Along the bridge direction, arrange measuring point 1 at the end of guide beam 2, i.e., the first coordinate monitoring unit; arrange measuring point 2 at the tail end of main beam 1, i.e., the second coordinate monitoring unit. Measuring points 1 and 2 are located at both ends of the longitudinal line of the bridge structure, respectively. After the main beam 1 is positioned and assembled, before jacking, measure the initial values ​​of the plane bridge position coordinates of measuring points 1 and 2, and record them as (X... 01 Y 01 ), (X 02 Y 02 Suppose there are i transverse jacking devices along the longitudinal direction of the bridge span, i = 1, 2, ..., n. Determine the longitudinal coordinate value (X) of the center of the jacking device on each temporary pier. D1 X D2 ..., X Dn For the layout of measuring points and temporary piers, please refer to [reference needed]. Figure 1 In this example, measuring points 1 and 2 are arranged on the same longitudinal line of the bridge structure, preferably on the central axis. Of course, they can also be placed at any position on the bridge structure, but before calculation, the detected coordinate data needs to be converted into the coordinates of two points on the central axis or the same longitudinal line according to their positional relationship, so as to facilitate subsequent calculation.

[0035] S1: Obtain the real-time planar coordinates of both ends of the longitudinal line of the bridge structure during the jacking process.

[0036] Specifically, automatic real-time tracking and measurement of the lateral deviation measuring points of the bridge are performed to obtain the real-time planar bridge position coordinates (X1, Y1) and (X2, Y2) of measuring points 1 and 2 at both ends of the longitudinal line of the bridge structure during the jacking operation. The automatic real-time tracking and measurement utilizes a wireless control total station—the SX-LK10 total station wireless control sampling instrument. A dynamic automatic tracking program is programmed to automatically track and measure the lateral deviation measuring points in real time, and the measured data is transmitted wirelessly via a 4G network to a designated IP address and port, integrated into the control module—the intelligent monitoring system. The method of automatically acquiring and transmitting the measuring point coordinates to the designated IP address and port in real time is not unique; it also includes some high-precision engineering positioning equipment, such as BeiDou remote displacement monitoring equipment.

[0037] S2: Determine the lateral offset of the bridge structure at the transverse jacking device based on the initial plane coordinates and real-time plane coordinates at both ends of the longitudinal line of the bridge structure and the longitudinal bridge coordinates of the transverse jacking device.

[0038] In this example, when (X1-X Di When X1 ∈ [0, X2], it indicates that the bridge structure was constructed by jacking in that section. The following algorithm holds true; if the value exceeds this range, it means that the bridge was not constructed by jacking in that section.

[0039] Step S2 specifically includes:

[0040] S21: Determine the lateral offset at both ends of the longitudinal line of the bridge structure based on the initial and real-time plane coordinates at both ends of the longitudinal line.

[0041] According to the formula Δy1=Y1-Y 01 and Δy2=Y2-Y 02 Determine the lateral offset at both ends of the longitudinal line of the bridge structure, where Y1 is the real-time lateral coordinate of the front end of the bridge structure, and Y... 01 Y is the initial lateral coordinate of the front end of the bridge structure, Δy1 is the lateral offset of the front end of the bridge structure, and Y2 is the real-time lateral coordinate of the rear end of the bridge structure. 02 Let y1 be the initial lateral coordinate of the tail end of the bridge structure, and Δy2 be the lateral offset of the tail end of the bridge structure.

[0042] S22: The lateral deviation at both ends of the longitudinal line of the bridge structure and the longitudinal coordinates of the lateral jacking equipment are used to determine the lateral deviation of the bridge structure at the lateral jacking equipment.

[0043] According to the formula Determine the lateral displacement Δy of the bridge structure at the i-th lateral jacking device. Di X1 is the real-time longitudinal coordinate of the front end of the bridge structure, and X2 is the real-time longitudinal coordinate of the rear end of the bridge structure. Di Let be the longitudinal coordinate of the i-th lateral jacking device.

[0044] S3: Correct the offset of the bridge structure based on the lateral deviation of the bridge structure at the lateral jacking equipment.

[0045] In some optional embodiments, when correcting the offset of the bridge structure based on the lateral deviation of the bridge structure at the lateral jacking device, the offset correction step of the bridge structure is performed when the lateral deviation at any lateral jacking device reaches the allowable lateral deviation of the beam.

[0046] The permissible lateral deviation of the beam is the limit of the permissible deviation specified in the standard or the permissible correction capability value of the jacking equipment.

[0047] Specifically, the allowable lateral deviation Δy0 of the beam is determined based on the minimum value of the allowable deviation limit specified in the code and the minimum allowable correction capability value of the jacking equipment. During the jacking process, when Δy Di When the beam exceeds the range of [-Δy0, Δy0] or when it is necessary to adjust the beam posture to assemble the next beam segment, preparation for correction action begins. The lateral correction command for each launching device is set to -Δy0. Di Implementation.

[0048] When longitudinally jacking a bridge structure, it is impossible to simultaneously correct the bridge structure's offset. The offset must be corrected before longitudinal jacking can continue. In this design, the offset correction step is only executed when the lateral deviation at any lateral jacking device reaches the allowable lateral deviation of the beam. This design improves construction efficiency and avoids frequent adjustments to lateral deviations.

[0049] In some alternative embodiments, when correcting the offset of the bridge structure, the correction is stopped if the lateral offset at all lateral jacking devices is less than or equal to the allowable error of the bridge structure.

[0050] In this example, according to the specifications, the allowable error of the bridge structure at which the lateral jacking equipment stops correcting the deviation is determined to be δy0. When Δy Di When Δy ∈ [-δy0, δy0], the lateral jacking equipment performs its correction action. The lateral jacking equipment has a certain margin of error. When the offset of the bridge structure is less than the allowable error, it is difficult to adjust it using the lateral jacking equipment, and at this point, the offset of the bridge structure will not affect construction safety. When Δy Di When ∈[-δy0,δy0], the lateral pushing equipment's correction action can improve work efficiency.

[0051] Originally, the above correction methods were built into the intelligent monitoring system, which would automatically identify the lateral correction amount of the lateral jacking equipment set above each temporary pier based on real-time automatic measurement data feedback.

[0052] By linking the digital controller of the jacking equipment with the intelligent monitoring system, the lateral correction amount is transmitted in the form of instructions. The digital controller automatically identifies the deviation of each lateral jacking device, automatically corrects the deviation when it exceeds the allowable range, and stops the correction when the beam returns to the specified state before proceeding to the next step. The lateral jacking process can realize the automated control of the lateral deviation of the bridge structure.

[0053] To facilitate understanding of the speed and accuracy of this correction method, constant values ​​are assigned to each parameter, and the lateral offset value Δy of each lateral jacking device is calculated. Di If the bridge is not within the jacking range Δy Di The value is 0. The parameters and calculation results are shown in the table below.

[0059] Two coordinate monitoring units are installed at both ends of the longitudinal line of the bridge structure to obtain the real-time plane coordinates of both ends of the longitudinal line of the bridge structure during jacking; multiple lateral jacking devices are installed on temporary supports set along the longitudinal direction of the bridge; the control module is used to determine the lateral deviation of the bridge structure at the lateral jacking device based on the initial plane coordinates, real-time plane coordinates and longitudinal coordinates of the lateral jacking devices at both ends of the longitudinal line of the bridge structure, and the longitudinal coordinates of the lateral jacking devices, and to control the lateral jacking devices to correct the offset of the bridge structure based on the lateral deviation of the bridge structure at the lateral jacking devices.

[0060] Specifically, according to the formula Δy1=Y1-Y 01 and Δy2=Y2-Y 02 Determine the lateral offset at both ends of the longitudinal line of the bridge structure, where Y1 is the real-time lateral coordinate of the front end of the bridge structure, and Y... 01 Y is the initial lateral coordinate of the front end of the bridge structure, Δy1 is the lateral offset of the front end of the bridge structure, and Y2 is the real-time lateral coordinate of the rear end of the bridge structure. 02 Let y1 be the initial lateral coordinate of the tail end of the bridge structure, and Δy2 be the lateral offset of the tail end of the bridge structure.

[0061] According to the formula Determine the lateral displacement Δy of the bridge structure at the i-th lateral jacking device.Di X1 is the real-time longitudinal coordinate of the front end of the bridge structure, and X2 is the real-time longitudinal coordinate of the rear end of the bridge structure. Di Let be the longitudinal coordinate of the i-th lateral jacking device.

[0062] In some alternative embodiments, the lateral jacking device includes two lateral jacking units, which are respectively located on both sides of the bridge structure in the lateral direction.

[0063] In this example, the lateral offset of the bridge structure is adjusted by setting two lateral jacking units on both sides of the bridge structure in the lateral direction.

[0064] In some optional embodiments, the coordinate monitoring unit employs a wireless total station. Automatic real-time tracking measurement utilizes the SX-LK10 wireless total station sampling instrument, which automatically tracks and measures the lateral offset at measuring points 1 and 2 in real time through a dynamically programmed automatic tracking mechanism. The measured data is then transmitted via a 4G wireless network to a designated IP address and port, integrated into the control module – the intelligent monitoring system. The method of automatically acquiring and transmitting the measuring point coordinates to the designated IP address and port in real time is not unique; it also includes some high-precision engineering positioning devices, such as BeiDou remote displacement monitoring equipment.

[0065] In addition, in this scheme, two coordinate monitoring units are respectively installed at both ends of the longitudinal line of the bridge structure, and the two coordinate monitoring units are located at both ends of the central axis of the bridge structure.

[0066] In summary, this adaptive correction method and device for bridge jacking optimizes the arrangement of measuring points during the jacking process. Only one coordinate monitoring unit needs to be set up at each end of the longitudinal line of the bridge structure to obtain the offset of the bridge structure at the location of each lateral jacking device. The lateral jacking devices can then be used to correct the bridge structure's deviation during the longitudinal jacking process, simplifying the setting of monitoring points, reducing costs, and improving construction efficiency. Furthermore, by combining automatic monitoring technology with the lateral displacement, lateral jacking devices, and control modules, the method can automatically and dynamically identify the lateral deviation of the bridge structure during jacking and quickly and accurately provide feedback on the correction amount of each lateral jacking device, effectively reducing labor costs and providing a technical reference for the establishment and optimization of an automated correction mechanism for bridge jacking.
