Description

Technical Field

[0001] This invention belongs to the field of trapezoidal pipe jacking construction technology, and specifically relates to an axis posture limiting and correction device and method suitable for trapezoidal pipe jacking. Background Technology

[0002] The horseshoe-shaped cross-section bundled pipe jacking is composed of multiple trapezoidal jacking pipes tightly connected by interlocking clips and steel strands. Its structural stress and forming quality are highly dependent on the axial accuracy of each jacking unit. Due to the misalignment of the centroid and centroid of the trapezoidal jacking pipes and the asymmetrical lateral forces, torsional deviations around the axis are easily generated during jacking, and these deviations have a cumulative amplification effect due to the interlocking connections between the jacking pipes. To ensure the successful arching of the pipe jacking and meet the requirements for prestressing tensioning, extremely stringent control indicators (less than or equal to ±12′) were imposed on the axial deviations of the trapezoidal jacking pipes, especially the angular deviations around their own axes. These standards far exceed those of conventional bundled pipe jacking projects, making the construction extremely difficult.

[0003] Existing pipe jacking correction devices are mostly designed for circular or rectangular cross-sections, and their correction mechanisms are insufficient to meet the three-dimensional attitude control requirements of trapezoidal cross-sections. They cannot effectively overcome the excessive deflection caused by the trapezoidal pipe jacking forming a horseshoe-shaped pipe curtain. Therefore, we propose an axial attitude limiting correction device and method suitable for trapezoidal pipe jacking to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an axial attitude limiting and correction device and method suitable for trapezoidal jacking pipes, thus solving the problem of difficulty in limiting and correcting the axial attitude of trapezoidal jacking pipes.

[0005] This invention is achieved through the following solution: an axis attitude limiting and correcting device suitable for trapezoidal jacking pipes, comprising: A frame is used to fix it at the starting well. The frame is enclosed to form a limiting and correction opening for the trapezoidal jacking pipe to be constructed to pass through. The central axis of the frame extends along the Y direction. The limiting and correcting mechanism includes multiple adjusting members distributed along the inner circumference of the limiting and correcting opening. Each adjusting member can be extended and retracted in a direction toward the inside of the limiting and correcting opening to push the trapezoidal jacking pipe to a corresponding position. The number and arrangement of the adjusting members satisfy the following: when selectively adjusting some of the adjusting members, the trapezoidal jacking pipe can be pushed to a Z-axis set position; when selectively adjusting some of the adjusting members, the trapezoidal jacking pipe can be pushed to an X-axis set position; when selectively adjusting some of the adjusting members, the trapezoidal jacking pipe can be deflected about the Y-axis. The data acquisition system is used to acquire the actual position and orientation of the trapezoidal jacking pipe in real time and output the deviation information of the actual position and orientation from the set position and orientation to the limit and correction mechanism. The deviation information includes X-axis deviation, Z-axis deviation and angular deviation with Y-axis as the axis. The number of the adjusting components is six, and they are divided into three pairs. One pair of adjusting components is symmetrically arranged at the left and right ends of the limiting and correcting port. The other two pairs of adjusting components are respectively arranged on both sides of the center line at the upper and lower ends of the limiting and correcting port. Each pair of adjusting components in the other two pairs is respectively arranged at the upper and lower ends of the limiting and correcting port. The adjusting component includes an opening on the frame and an adjusting block movably disposed within the opening for close contact with the trapezoidal jacking pipe, with a gap between the adjusting block and the inner wall of the opening. The adjusting component also includes two driving components for extending into the movable opening and respectively abutting against the two sides of the centerline of the end of the adjusting block away from the trapezoidal jacking pipe. The length of the driving components extending into the movable opening is adjustable. When the trapezoidal jacking pipe is pushed to deflect at an angle with the Y-axis, the length of the two driving components in each of the selected adjusting components extending into the movable opening is adjusted so that all the adjusting blocks deflect at the corresponding angle in the corresponding movable opening, so that all the adjusting blocks are always in close contact with the trapezoidal jacking pipe. The limiting and correcting device also includes a fastener group, which is used to fix all the adjusting blocks in the corresponding movable opening after the position of the trapezoidal jacking pipe is adjusted; the fastener group includes six fasteners that correspond one-to-one with the six adjusting components, and each of the fasteners includes a stopper for pressing against the corresponding adjusting block and fixing it in the movable opening.

[0006] A further improvement of the present invention for the axis attitude limiting and correcting device of trapezoidal jacking pipe is that the adjusting block in the adjusting member located at the upper and lower ends of the limiting and correcting port has a horizontal contact surface with the trapezoidal jacking pipe, and the adjusting block in the adjusting member located at the left and right ends of the limiting and correcting port has a wedge-shaped contact surface with the trapezoidal jacking pipe.

[0007] A further improvement of the present invention for the axial attitude limiting and correcting device of trapezoidal jacking pipe is that baffles are fixedly connected to the inner walls of both ends of the limiting and correcting port to block the adjusting block and prevent the adjusting block from moving in the Y direction along the trapezoidal jacking pipe due to contact friction.

[0008] A method for axial posture limiting and correction suitable for trapezoidal jacking pipes, employing the limiting and correction device as described above, includes the following steps: S1. The actual position and orientation of the trapezoidal jacking pipe are collected in real time using the data acquisition system, and the deviation information of the actual position and orientation from the set position and orientation is output and sent to the limit correction mechanism. S2. Based on the deviation information, adjust the abutment corresponding to the drive component requiring adjustment so that it does not contact the corresponding adjustment block. This is done by: shortening the length of the drive component extending into the movable opening at the upper end and lengthening the length of the drive component extending into the movable opening at the lower end; and shortening the length of the drive component extending into the movable opening at the lower end and lengthening the length of the drive component extending into the movable opening at the upper end, so that the corresponding adjustment block pushes the trapezoidal jacking pipe to the Z-direction set position, and then adjusting the corresponding abutment to be pressed against the corresponding adjustment block; and / or Adjusting the abutment corresponding to the drive component requiring adjustment so that it does not contact the corresponding adjusting block, by: shortening the length of the drive component extending into the movable opening at the left end and lengthening the length of the drive component extending into the movable opening at the right end, and vice versa, so that the corresponding adjusting block pushes the trapezoidal jacking tube to the X-direction set position, and then adjusting the corresponding abutment to be pressed against the corresponding adjusting block; and / or Adjusting the abutment corresponding to the drive component that needs adjustment so that it does not contact the corresponding adjusting block, by: shortening the length of the drive component extending into the movable opening on the upper right side, shortening the length of the drive component extending into the movable opening on the lower left side, shortening the length of the drive component extending into the movable opening on the upper left side, shortening the length of the drive component extending into the movable opening on the lower right side, lengthening the length of the drive component extending into the movable opening on the upper left side, lengthening the length of the drive component extending into the movable opening on the lower right side, lengthening the length of the drive component extending into the movable opening on the lower left side, lengthening the length of the drive component extending into the movable opening on the upper right side, and shortening the length of the drive component extending into the movable opening on the upper left side. The length of the drive member extending into the movable opening is adjusted by shortening the length of the drive member extending into the movable opening at the lower right end, shortening the length of the drive member extending into the movable opening at the lower left end, shortening the length of the drive member extending into the movable opening at the upper right end, lengthening the length of the drive member extending into the movable opening at the upper right end, lengthening the length of the drive member extending into the movable opening at the lower left end, lengthening the length of the drive member extending into the movable opening at the upper left end, and lengthening the length of the drive member extending into the movable opening at the lower right end, so that the corresponding adjusting block pushes the trapezoidal jacking pipe to deflect angularly around the Y-axis, and then the corresponding abutment is adjusted to abut against the corresponding adjusting block; until the adjusted trapezoidal jacking pipe posture reaches the set posture.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention can dynamically adjust the positional deviation output by the data acquisition system in real time, thereby strictly controlling the axial deviation within the design allowable range during the pipe jacking process, providing reliable technical support for the smooth construction and high-quality forming of the horseshoe-shaped cross-section bundled pipe curtain.

[0017] To address the difficulty in correcting the deviation of trapezoidal jacking pipes, this invention provides an axis attitude limiting and correcting device and method suitable for trapezoidal jacking pipes. The following detailed description, in conjunction with specific embodiments and accompanying drawings, further illustrates this axis attitude limiting and correcting device and method suitable for trapezoidal jacking pipes.

[0018] See Figures 1-7 As shown, an axis attitude limiting and correction device suitable for trapezoidal jacking pipes includes: Frame 1 is used to fix it at the starting well. The frame 1 is enclosed to form a limiting and correction port 2 for the trapezoidal jacking pipe 9 to be constructed to pass through. The central axis of the frame 1 extends along the Y direction (Y direction is the direction of the construction axis). The limiting and correcting mechanism includes multiple adjusting components distributed along the inner circumference of the limiting and correcting opening 2. Each adjusting component can be extended or retracted in the direction toward the inside of the limiting and correcting opening 2 to push the trapezoidal jacking pipe 9 to the corresponding position. The number and arrangement of the adjusting components satisfy the following: when selectively adjusting some adjusting components, the trapezoidal jacking pipe 9 can be pushed to the Z-direction set position; when selectively adjusting some adjusting components, the trapezoidal jacking pipe 9 can be pushed to the X-direction set position; when selectively adjusting some adjusting components, the trapezoidal jacking pipe 9 can be deflected about the Y-direction as the axis. The data acquisition system is used to acquire the actual position and orientation of the trapezoidal jacking pipe 9 in real time and output the deviation information of the actual position and orientation from the set position and orientation to the limit correction mechanism. The deviation information includes the X-axis deviation, the Z-axis deviation and the angle deviation with the Y-axis as the axis.

[0019] By adopting the above design, the positional deviation output by the data acquisition system can be dynamically adjusted in real time, thereby strictly controlling the axial deviation within the design allowable range during the pipe jacking process, providing reliable technical support for the smooth construction and high-quality forming of the horseshoe-shaped cross-section bundled pipe curtain.

[0020] Furthermore, the adjustment components for adjusting the Z-axis position are located at the upper and lower ends of the frame, the adjustment components for adjusting the X-axis position are located at the left and right ends of the frame, and the adjustment components for adjusting the deflection angle are all the adjustment components for adjusting the Z-axis and X-axis positions.

[0021] Among them, see Figure 1 , Figure 4 As shown, there are six adjusting components, which are divided into three pairs. One pair of adjusting components is symmetrically arranged at the left and right ends of the limiting and correcting port 2. The other two pairs of adjusting components are respectively arranged on both sides of the center line at the upper and lower ends of the limiting and correcting port 2. Each pair of adjusting components in the other two pairs is respectively arranged at the upper and lower ends of the limiting and correcting port 2.

[0022] See Figure 4 As shown, the adjusting component includes an adjustable opening 8 opened on the frame 1 and an adjusting block 3 movably disposed in the adjustable opening 8 for close contact with the trapezoidal jacking pipe 9. A gap is left between the adjusting block 3 and the inner wall of the adjustable opening 8. The adjusting component also includes two driving components for extending into the movable opening 8 and respectively abutting against the two sides of the centerline of the end of the adjusting block 3 away from the trapezoidal jacking pipe 9. The length of the driving components extending into the movable opening 8 is adjustable. When the trapezoidal jacking pipe 9 is pushed and deflected at an angle around the Y-axis, the length of the two driving parts in each selected adjusting component that extend into the movable opening 8 is adjusted so that all adjusting blocks 3 deflect at the corresponding angle within the corresponding movable opening 8, so that all adjusting blocks 3 are always in close contact with the trapezoidal jacking pipe 9.

[0023] Further, see Figure 4 As shown, the two adjusting components located on both sides of the upper center line of the limiting and correcting port 2 are adjusting component a and adjusting component b, the two adjusting components located on both sides of the lower center line of the limiting and correcting port 2 are adjusting component c and adjusting component d, and the two adjusting components located at the left and right ends of the limiting and correcting port 2 are adjusting component e and adjusting component f.

[0024] In this embodiment, by simultaneously adjusting adjusting member a and adjusting member b to shorten towards the inside of the limiting correction port 2, simultaneously adjusting adjusting member c and adjusting member d to extend towards the inside of the limiting correction port 2, and simultaneously adjusting adjusting member c and adjusting member d to shorten towards the inside of the limiting correction port 2, and simultaneously adjusting adjusting member a and adjusting member b to extend towards the inside of the limiting correction port 2, the corresponding adjusting block 3 pushes the trapezoidal jacking pipe 9 to adjust its position in the Z direction. By adjusting the adjusting element e to shorten in the direction of the limiting correction port 2 and adjusting the adjusting element f to extend in the direction of the limiting correction port 2, the corresponding adjusting block 3 pushes the trapezoidal jacking pipe 9 to adjust its position in the X direction. By: shortening the length of the driving component extending into the movable opening in adjusting member b, shortening the length of the driving component extending into the movable opening in adjusting member c, shortening the length of the upper driving component extending into the movable opening in adjusting member e, shortening the length of the lower driving component extending into the movable opening in adjusting member f, lengthening the length of the driving component extending into the movable opening in adjusting member a, lengthening the length of the driving component extending into the movable opening in adjusting member d, lengthening the length of the lower driving component extending into the movable opening in adjusting member e, lengthening the length of the upper driving component extending into the movable opening in adjusting member f, and shortening the length of the driving component extending into the movable opening in adjusting member a. The lengths of the moving opening, the lengths of the driving component in the shortening adjustment piece d extending into the moving opening, the lengths of the driving component in the lower part of the shortening adjustment piece e extending into the moving opening, the lengths of the driving component in the upper part of the shortening adjustment piece f extending into the moving opening, the lengths of the driving component in the lengthening adjustment piece b extending into the moving opening, the lengths of the driving component in the lengthening adjustment piece c extending into the moving opening, the lengths of the driving component in the upper part of the lengthening adjustment piece e extending into the moving opening, and the lengths of the driving component in the lower part of the lengthening adjustment piece f extending into the moving opening are adjusted so that the corresponding adjusting block 3 pushes the trapezoidal jacking pipe to deflect at an angle about the Y-axis.

[0025] Further, see Figure 1 As shown, the frame 1 is provided with lifting holes 7 to facilitate the hoisting of the entire device.

[0026] Furthermore, the driving component is preferably a hydraulic cylinder, which is mounted on the frame 1. The extension and retraction of the hydraulic cylinder realizes the adjustment of the jacking trapezoidal jacking pipe 9, so as to achieve automatic adjustment.

[0027] See Figure 4As shown, in this embodiment, each driving component includes two adjusting bolts 4. The frame 1 has two adjusting screw holes, and the two adjusting screw holes are connected to the limiting and correcting port 2. The two adjusting bolts 4 are respectively screwed into the two adjusting screw holes. By screwing the adjusting bolts 4 on the two driving components, the adjusting block 3 is pressed against the trapezoidal top pipe 9. Each drive unit also includes two servo-electric screw adjustment components (not shown in the figure, these servo-electric screw adjustment components are existing products available on the market) connected to the two adjustment bolts 4 respectively. The servo-electric screw adjustment components drive the adjustment bolts 4 to rotate and move, thereby pushing the adjustment block 3 to fit tightly against the trapezoidal jacking pipe 9, so as to achieve automatic adjustment.

[0028] See Figure 4 As shown, the adjusting block 3 includes a push block 302, a sealing block 301, and multiple connecting bolts 303. The push block 302 and the sealing block 301 are fixed together as a whole by multiple connecting bolts 303. The push block 302 is in contact with the driving component, and the sealing block 301 is in contact with the trapezoidal jacking pipe 9. The sealing block 301 is made of high-strength, high-toughness, and low-friction material. When the sealing block 301 is severely worn, it can be replaced after completion to extend the service life of the entire device.

[0029] Among them, see Figure 4 As shown, the adjusting block 3 in the adjusting components located at the upper and lower ends of the limiting and correcting port 2 has a horizontal contact surface with the trapezoidal jacking pipe 9, while the adjusting block 3 in the adjusting components located at the left and right ends of the limiting and correcting port 2 has a wedge-shaped contact surface with the trapezoidal jacking pipe 9.

[0030] Since the top and bottom surfaces of the existing trapezoidal jacking pipe 9 are horizontal, and the left and right sides are wedge-shaped, by adopting the above design, the adjusting blocks 3 at the top and bottom ends and the adjusting blocks 3 at the left and right ends can be fitted tightly to the trapezoidal jacking pipe 9, maximizing the contact area between them, which can limit the trapezoidal jacking pipe 9 during the jacking process, improve the limiting effect, and achieve precise guidance.

[0031] The limiting and correcting device also includes a fastener group, which is used to fix all the adjusting blocks 3 in the corresponding movable openings 8 after the position of the trapezoidal jacking pipe 9 has been adjusted.

[0032] The fastener group includes multiple fasteners, each corresponding to one of the six adjusting components. Each fastener includes a retainer for abutting against the corresponding adjusting block 3 and fixing it in the movable opening 8; By adopting the above design, after the position of the trapezoidal jacking pipe 9 is adjusted, the adjusting block 3 is fixed in the corresponding movable opening 8 using the abutment, which can greatly improve the stability of the adjusting block 3 and thus improve the limiting effect on the trapezoidal jacking pipe 9. Before adjusting the position of the trapezoidal jacking pipe 9, it is necessary to first adjust the abutment corresponding to the driving component to be adjusted so that it does not contact the corresponding adjusting block, and then adjust the corresponding adjusting component.

[0033] Furthermore, the abutment is preferably a hydraulic cylinder, which can abut against or not contact the corresponding adjusting block through the extension and retraction of the hydraulic cylinder, so as to achieve automatic adjustment.

[0034] See Figure 1 As shown, in this embodiment, the fixing component includes a fixing bolt 5 and a fixing screw hole. The fixing screw hole is opened on the frame 1 and is connected to the corresponding movable opening 8. The fixing bolt 5 is screwed into the fixing screw hole. By screwing the fixing bolt 5 against the corresponding adjusting block 3, the adjusting block 3 is fixed in the corresponding movable opening 8.

[0035] Each fastener contains four fixing bolts 5 and four fixing screw holes. The fixing effect of the adjusting block 3 can be further improved by using multiple fixing bolts 5.

[0036] Each fastener also includes four servo-electric screw adjustment components connected to the four fixing bolts 5 respectively. The fixing bolts 5 are turned by the servo-electric screw adjustment components to adjust their length of insertion into the movable port 8, thereby achieving both pressing against the fixing adjustment block 3 and not contacting the adjustment block 3. The entire adjustment process is automated.

[0037] Among them, see Figure 1 and Figure 2 As shown, baffles 6 are fixedly connected to the inner walls of both ends of the limiting and correcting port 2 to block the adjusting block 3, so as to prevent the adjusting block 3 from moving in the Y direction along with the trapezoidal jacking pipe 9 due to contact friction.

[0038] By adopting the above design, the baffle 6 can block the adjusting blocks 3 located at the left and right ends, so as to prevent the trapezoidal jacking pipe 9 from sliding and falling off along with the trapezoidal jacking pipe 9 due to the friction between the trapezoidal jacking pipe 9 and the limiting block during the jacking process.

[0039] A method for axial attitude limiting and correction suitable for trapezoidal jacking pipes, employing the aforementioned limiting and correction device, includes the following steps: S1. The actual position and orientation of the trapezoidal jacking pipe are collected in real time using the data acquisition system, and the deviation information of the actual position and orientation from the set position and orientation is output and sent to the limit correction mechanism. S2. Based on the deviation information, adjust the abutment corresponding to the drive component that needs adjustment so that it is not in contact with the corresponding adjustment block 3. This is done by: shortening the length of the drive component extending into the movable opening 8 at the upper end and lengthening the length of the drive component extending into the movable opening 8 at the lower end; and vice versa. This causes the corresponding adjustment block 3 to push the trapezoidal jacking pipe 9 to the Z-direction set position. Then, adjust the abutment to be pressed tightly against the corresponding adjustment block 3 (see...). Figure 5 (as shown); and / or Adjust the abutment corresponding to the drive component that needs adjustment so that it is not in contact with the corresponding adjustment block 3. This is done by: shortening the length of the drive component extending into the movable opening 8 at the left end and lengthening the length of the drive component extending into the movable opening 8 at the right end; then shortening the length of the drive component extending into the movable opening 8 at the right end and lengthening the length of the drive component extending into the movable opening 8 at the left end, so that the corresponding adjustment block 3 pushes the trapezoidal jacking tube 9 to the X-direction set position. Then, adjust the abutment to be pressed tightly against the corresponding adjustment block 3 (see...). Figure 6 (as shown); and / or Adjusting the abutment corresponding to the drive component that needs adjustment so that it does not contact the corresponding adjusting block 3, by: shortening the length of the drive component extending into the movable opening 8 on the upper right side, shortening the length of the drive component extending into the movable opening 8 on the lower left side, shortening the length of the drive component extending into the movable opening 8 on the upper left side, shortening the length of the drive component extending into the movable opening 8 on the lower right side, lengthening the length of the drive component extending into the movable opening 8 on the upper left side, lengthening the length of the drive component extending into the movable opening 8 on the lower right side, lengthening the length of the drive component extending into the movable opening 8 on the lower left side, lengthening the length of the drive component extending into the movable opening 8 on the upper right side, and shortening the length of the drive component extending into the movable opening 8 on the upper left side. The length of the driving component extending into the movable opening 8 is adjusted as follows: shortening the length of the driving component extending into the movable opening 8 on the lower right side, shortening the length of the driving component extending into the movable opening 8 on the lower left side, shortening the length of the driving component extending into the movable opening 8 on the upper right side, lengthening the length of the driving component extending into the movable opening 8 on the upper right side, lengthening the length of the driving component extending into the movable opening 8 on the lower left side, lengthening the length of the driving component extending into the movable opening 8 on the upper left side, and lengthening the length of the driving component extending into the movable opening 8 on the lower right side, so that the corresponding adjusting block 3 pushes the trapezoidal jacking pipe 9 to deflect angularly about the Y-axis, and then adjusting the corresponding abutment to be pressed against the corresponding adjusting block 3 (see...). Figure 7 (as shown); until the adjusted trapezoidal jacking pipe 9 position reaches the set position.
