Abstract
Description
Technical Field
[0001] This invention relates to tunnel construction, and more particularly to a rectangular pipe jacking machine attitude monitoring device and adjustment method based on multiple references. Background Technology
[0002] During tunnel construction, tunnel boring machines (TBMs) are typically used for excavation, while pipe jacking machines are used for excavation in rectangular tunnels. Regardless of the method, equipment is required to excavate inside the tunnel. However, currently, it is difficult to monitor the attitude of pipe jacking machines during excavation. There are no reference points inside the tunnel, making it difficult to determine if there is any deviation in the excavation attitude or to monitor the excavation direction. Even with ground base stations, significant errors still exist. Because the tunnel is underground, ground base station signals generally require long-wave transmission, which results in less transmitted information and lower propagation accuracy. If the tunnel excavation depth is large, positioning becomes even more difficult, leading to frequent location mapping during pipe jacking machine construction and resulting in low construction efficiency.
[0003] Therefore, it is necessary to design a rectangular pipe jacking machine attitude monitoring device and adjustment method based on multiple references to solve the above problems. Summary of the Invention

Through the cooperation of displacement device, angle device, monitoring device, assembly device, motor device and reference device, the attitude of the pipe jacking machine during tunnel construction can be accurately monitored. The attitude monitoring of the pipe jacking machine is quantified, and it can provide accurate data support when the pipe jacking machine is correcting its course. The accuracy is not affected by the ground depth and can be set as a reference for various construction routes in the tunnel.

[0052] By employing multiple sets of reference devices deployed within the tunnel, and by laying a solid reference surface at the bottom of the tunnel and the ground shaft as a reference benchmark for tunnel construction, the rectangular pipe jacking machine attitude monitoring equipment based on multiple reference objects can achieve precise control over its own attitude, further ensuring the attitude monitoring of the pipe jacking machine. At the same time, it can solve the problem of poor ground base station signal during the construction of deep tunnels, and can accurately set the tunnel construction direction.
[0053] Example 4
[0054] like Figures 1-16 As shown, an adjustment method for a rectangular pipe jacking machine attitude monitoring device based on multiple references is described:
[0055] When the pipe jacking machine is inside the tunnel, the rectangular pipe jacking machine attitude monitoring device based on multiple reference points can be placed inside a section of the excavated standard route tunnel, with the device positioned behind the pipe jacking machine. The assembly device 8 is then horizontally and vertically installed at the center of the back side of the pipe jacking machine. The device is then installed inside the tunnel via an external support 102. The mounting frame 4 is rotated via an arc-shaped electric slide rail 2, and the device is kept horizontal and vertical using a spirit level or level instrument. The device is aligned with the desired tunnel excavation direction. With the assembly device 8 and the monitoring device 7 aligned on the same centerline, the rectangular pipe jacking machine attitude monitoring equipment based on multiple reference points can then be activated. When the pipe jacking machine is in the tunneling state, the assembly device 8 can be activated, emitting high-frequency pulse light signals. One signal indicates the position of the assembly device 8 (one signal), and the other indicates the distance to the assembly device 8 (two signals). The high-frequency pulse light signals emitted by the assembly device 8 will illuminate the monitoring device 7. The monitoring device 7 will analyze the emitted high-frequency light signals, analyzing the emission distance and emission position, i.e., enabling the monitoring device... The position and distance of the assembly device 8 are analyzed by the monitoring device 7. By analyzing the position and distance of the assembly device 8, the position and distance of the pipe jacking machine can be determined. Furthermore, the tunneling posture of the pipe jacking machine can be determined from the analyzed position and distance. When the monitoring device 7 receives and analyzes the high-frequency pulse light signal emitted by the assembly device 8 in real time, if the tunneling position of the pipe jacking machine shifts, the light signal emitted by the assembly device 8 will also shift at the monitoring device 7. In this case, the monitoring device 7 will receive light signals emitted by the assembly device 8 from different positions, and the light signal indicating distance emitted by the assembly device 8 will not be able to illuminate the monitoring device 7. At this time, the monitoring device 7 loses the light signal indicating distance. When the monitoring device 7 is in operation, the displacement device 5 will control the displacement device 5 to work. The displacement device 5 will drive the angle device 6 and the monitoring device 7 to run parallel or vertically, so that the center of the monitoring device 7 will move back to the position light signal emitted by the assembly device 8. If the center of the monitoring device 7 receives the position light signal and the distance light signal after the displacement device 5 is running, and the distance expressed by the two light signals is equal, it means that the assembly device 8 is in a linear offset in one direction, horizontal, vertical or longitudinal. It can be known that the pipe jacking machine is in this offset state. And through the displacement information of the displacement device 5, the linear offset value of the assembly device 8 and the pipe jacking machine can be known.If, after the displacement device 5 is activated, the center of the monitoring device 7 only receives a light signal indicating position, and there is only one light signal indicating distance or it cannot be received by the monitoring device 7, it indicates that the assembly device 8 and the pipe jacking machine are axially offset on one or more axes, that is, the pipe jacking machine is tilted on one or more axes. At this time, the monitoring device 7 will control the angle device 6 to operate, and the angle device 6 will drive the monitoring device 7 to rotate on three axes, so that the monitoring device 7 can perform scanning work until the monitoring device 7 receives the two light signals indicating distance again. At this time, the axial displacement of the assembly device 8 and the pipe jacking machine can be known through the rotation information of each axis of the angle device 6. Offset values; After determining the offset values of the pipe jacking machine and the assembly device 8, the pipe jacking machine can be precisely corrected. During the pipe jacking machine correction process, the monitoring device 7 will also receive optical signals in real time. Once the displacement device 5 and the angle device 6 are reset, it can be determined that the pipe jacking machine is in the required tunneling posture. Thus, through the high-frequency pulse signals emitted by the assembly device 8, and through the receiving status of the monitoring device 7 and the control of the displacement device 5 and the angle device 6, the tunneling posture of the pipe jacking machine in the tunnel can be quickly understood, and the posture of the pipe jacking machine can be precisely quantified to facilitate correction. This provides precise data support for the pipe jacking machine correction process.
[0056] When the monitoring device 7 does not receive a position-indicating light signal emitted by the assembly device 8 at its center, that is, when the position-indicating light signal emitted by the assembly device 8 is at a non-central position of the monitoring device 7, the monitoring device 7 will control the horizontal electric slide rail 52 and the vertical electric slide rail 54 to move, causing the angle device 6 and the monitoring device 7 to move linearly, thereby moving the center of the monitoring device 7 to the position-indicating light signal emitted by the assembly device 8; through the displacement information of the horizontal electric slide rail 52 and the vertical electric slide rail 54, the linear offset value of the assembly device 8 and the pipe jacking machine can be known.
[0057] When the monitoring device 7 receives a position-indicating light signal emitted from the assembly device 8 at its center, and the distance-indicating light signal emitted from the assembly device 8 is not received by the monitoring device 7, the monitoring device 7 will control the forward servo motor 64, the vertical servo motor 67, and the longitudinal servo motor 610 to operate, causing the forward rotating frame 63, the vertical rotating frame 66, and the longitudinal rotating frame 69 to rotate, thereby causing the monitoring device 7 to rotate on three axes until the monitoring device 7 receives two distance-indicating light signals emitted from the assembly device 8; through the rotation information of the forward servo motor 64, the vertical servo motor 67, and the longitudinal servo motor 610, the axial offset values of the assembly device 8 and the pipe jacking machine can be determined.
[0058] The position-indicating light signal emitted by the assembly device 8 illuminates the matrix photosensitive sensor 72. The initial position is determined by the light illuminating the central independent unit of the matrix photosensitive sensor 72, which corresponds to the center of the direction of the tunnel excavation. The distance-indicating light signal emitted by the assembly device 8 illuminates the first laser ranging receiver 73. When the pipe jacking machine and the assembly device 8 experience positional shifts during excavation, the position-indicating light signal emitted by the assembly device 8 will illuminate a non-central unit of the matrix photosensitive sensor 72, while the distance-indicating light signal will not be received by the first laser ranging receiver 73. In this case, the installation module 71 will be moved by the shifting light. The installation module 71 is moved so that the central unit of the matrix photosensitive sensor 72 moves toward the position indicated by the light signal, enabling the central unit of the matrix photosensitive sensor 72 to receive the position indicated by the light signal. If the upper unit of the matrix photosensitive sensor 72 receives the position indicated by the light signal, the installation module 71 will be moved downwards. After this, if neither of the first laser rangefinders 73 receives the distance indicated by the light signal, the installation module 71 will rotate so that both of the first laser rangefinders 73 can receive the distance indicated by the light signal. In this way, the angle and relative position of the installation module 71 indicate the angle and relative position of the pipe jacking machine.
[0059] The assembly frame 81 can be installed at the center of the back side of the pipe jacking machine. When the light emitter and the first laser rangefinder 83 are activated, three high-frequency pulse light signals will be emitted. One of them is a light signal indicating the position of the assembly device 8, and there is one of them. The other two are light signals indicating the distance of the assembly device 8.
[0060] Activating the tracked motorized wheel module 95 enables the rectangular pipe jacking machine attitude monitoring device based on multiple references to move rapidly within the tunnel. Furthermore, by controlling the directional servo motor 94 and the electric push rod 91, the height position and tilt angle of the support frame 1 can be changed to cope with the uneven terrain after excavation within the tunnel, allowing the rectangular pipe jacking machine attitude monitoring device based on multiple references to maintain the required attitude within the tunnel.
[0061] In the early stages of tunnel construction, a set of reference devices 10 can be installed at the bottom of the vertical shaft connecting the tunnel to the ground, and a solid reference surface can be laid as a reference for tunnel construction. The external frame 101 of the set of reference devices 10 can be installed on the reference surface, and the second laser ranging transmitter 109 can be oriented towards the tunnel excavation direction. When the rectangular pipe jacking machine attitude monitoring equipment based on multiple reference objects is placed in the tunnel, the second laser ranging transmitter 109 can be activated to emit a high-frequency pulse light signal. This light signal is a reference light signal, which is directed to the positioning component 11. After the positioning component 11 receives the light signal, the distance between the rectangular pipe jacking machine attitude monitoring equipment based on multiple reference objects and the reference position, as well as its own attitude, can be determined. During the tunnel construction process, multiple sets of reference devices 10 can be deployed in the tunnel, with the reference devices 10 interconnected through the second laser ranging transmitter 109 and the second laser ranging receiver 103. The system establishes a communication mechanism, with the innermost set of reference devices 10 serving as relay reference points for the rectangular pipe jacking machine attitude monitoring equipment based on multiple reference points. Through communication between the second laser ranging transmitter 109 and the second laser ranging receiver 103, each reference device 10 can function as a reference. During tunnel curves or slope construction, the angle of the second laser ranging transmitter 109 can be adjusted by controlling the first adjusting servo motor 106 and the second adjusting servo motor 1010, enabling it to emit light signals with an angle relative to the reference position. After analyzing the angles and distances between multiple sets of reference devices 10, the distance between two reference devices 10 can be used as a chord length to precisely control the curve position of the rectangular pipe jacking machine attitude monitoring equipment based on multiple reference points. This allows the equipment to assist the pipe jacking machine in achieving accuracy during tunnel curve construction.
[0062] The light signal emitted from the second laser ranging transmitter 109 at the innermost part of the tunnel will illuminate the host laser ranging receiver 112. Through the reference light signals emitted by the two second laser ranging transmitters 109, the rectangular pipe jacking machine attitude monitoring equipment based on multiple reference objects can have precise control over its own attitude, further ensuring the attitude monitoring of the pipe jacking machine. At the same time, it can solve the problem of poor ground base station signal during the construction of deep tunnels, and can accurately set the tunnel construction direction.
[0063] By combining displacement devices, angle devices, monitoring devices, assembly devices, motor devices, and reference devices, the posture of the pipe jacking machine during tunnel construction can be precisely monitored. The posture monitoring of the pipe jacking machine is quantifiable, providing accurate data support when the pipe jacking machine is correcting its course. The accuracy is not affected by the ground depth and can be referenced for setting various construction routes within the tunnel.
[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
