Description

Technical Field

[0001] The present application relates to the field of pipeline construction, and in particular to a pipe jacking construction deviation correction device, a deviation correction method and a storage medium thereof. Background Art

[0002] Pipe jacking construction is a pipeline burial construction technology with no excavation or less excavation, which is often used in the construction of underground pipeline projects in modern cities. Its advantage is that the pipeline can be pushed into the soil according to the designed slope and direction without excavating the ground, thereby avoiding the impact on ground traffic and buildings, reducing environmental damage, and lowering construction costs.

[0003] When carrying out pipe jacking construction, two working wells are often dug first, one as the construction starting well at the initial position, and the other as the receiving well at the end point. In the working well, the pipe jacking machine is pushed in by a jack, and then the jacking pieces (that is, sections of pipes) are connected to the pipe jacking machine one by one and the pipe jacking machine is pushed in. However, since the two working wells are far apart, once the pipe jacking machine shifts underground, although the offset angle is small, the longer the jacking distance, the larger the offset will be. Now, additional working wells are often opened at a certain distance for the pipe jacking machine to pass through and to check whether the pipe jacking machine is offset. However, this also leads to increased workload, increased costs, and extended construction period. Summary of the invention

[0054] The following is combined with Figure 1-9 This application is described in further detail.

[0055] The present application embodiment discloses a pipe jacking construction correction device. Figure 1 and Figure 2 The pipe jacking construction correction device includes a straightness detection part 1 installed on the pipe jacking machine and the top plate, a plurality of jacking cylinders 11 fixedly connected in the construction starting well, and a data processing module 12. The ends of the telescopic rods of the plurality of jacking cylinders 11 are all pushed on the pipe jacking machine or the top plate to perform jacking. The straightness detection part 1 is used to detect the straightness of the pipe jacking machine and the top plate, and obtain the received coordinate data. The data processing module 12 is used to receive the coordinate data, obtain the correction signal after calculation and output it, and the plurality of jacking cylinders 11 receive the correction signal to perform jacking on the top plate with corresponding force and direction. In this embodiment, the end of the pipe jacking machine that contacts the soil for excavation along the jacking direction is used as the front end.

[0056] Reference Figure 3, the outer wall of the pipe jacking machine and the top sheet are fixedly connected with a protective tube 13, and the straightness detection member 1 includes a transmitter 2 and a receiver 21 installed in the protective tube 13. In this embodiment, the straightness detection member 1 can be, for example, an infrared distance sensor or a laser distance sensor or other sensors with distance detection function. The transmitter 2 is fixedly connected to the inner wall of the protective tube 13 near the front end of the pipe jacking machine, and the transmitter 2 is only fixedly connected to the protective tube 13 on the side wall of the pipe jacking machine. The front end of the protective tube 13 on the side wall of the pipe jacking machine is sealed, and the protective tube 13 on the top sheet is through-set at both ends. The receiver 21 is located at a position of the protective tube 13 away from the front end of the pipe jacking machine. The receiver 21 obtains the receiving coordinate data according to the positional relationship with the transmitter 2. The receiver 21 slides in the protective tube 13, and the receiver 21 can slide from one protective tube 13 to the next protective tube 13, so that the distance between the receiver 21 and the transmitter 2 includes all top sheets and pipe jacking machines. The cross-sectional diameter of the inner space of the protection tube 13 is polygonal, and for ease of description, is square in this embodiment, while the transmitting element 2 and the receiving element 21 are both cuboids adapted to the inner space of the protection tube 13 .

[0057] Reference Figure 3 and Figure 4 A limiting groove 3 is provided on the inner wall of the protection tube 13 away from the front end of the pipe jacking machine, and a limiting block 31 is slid in the limiting groove 3. The limiting block 31 can be completely retracted into the limiting groove 3, or the end thereof can be slid into the protection tube 13, and abut against the side wall of the end of the receiving member 21 away from the transmitting member 2, so as to limit the receiving member 21 from sliding out of the protection tube 13. A limiting spring 32 for ejecting the limiting block 31 is also installed in the limiting groove 3, one end of the limiting spring 32 abuts against the bottom wall of the limiting groove 3 facing its own opening surface, and the other end of the limiting spring 32 abuts against the end side wall of the limiting block 31 close to the bottom wall of the limiting groove 3. The limiting spring 32 is always in a compressed state, and expands and contracts in the direction of ejecting the limiting block 31 from the limiting groove 3 into the protection tube 13.

[0058] Reference Figure 3 and Figure 4 and Figure 5A trigger block 33 is fixedly connected to the outer wall of the end of the protection tube 13 near the launcher 2, and a trigger groove 34 is provided on the inner wall of the limit groove 3 away from the launcher 2. The trigger groove 34 extends through the direction away from the launcher 2 for the trigger block 33 to be inserted. A retreat groove 35 is provided on the side wall of the limit block 31 facing the trigger groove 34. The opening of the retreat groove 35 is connected to the trigger groove 34. The inner wall of the retreat groove 35 near the bottom wall of the limit groove 3 is inclined. The inclined inner wall of the retreat groove 35 is inclined in a direction that the deeper the retreat groove 35 is, the farther away from the bottom wall of the limit groove 3. The trigger block 33 is inserted and abutted against the inclined inner wall of the retreat groove 35 to push the limit block 31 to completely retreat into the limit groove 3, so as to release the abutment and limit of the receiving member 21, so that the receiving member 21 can slide from this protection tube 13 to the adjacent protection tube 13.

[0059] Reference Figure 6 The outer wall of the protection tube 13 on the top sheet away from the top sheet is provided with a through groove 4 and a sealing groove 41 which are connected to each other. The through groove 4 and the sealing groove 41 run through the entire length direction of the protection tube 13 along the extension direction of the top sheet, and in the thickness direction of the protection tube 13, the sealing groove 41 is connected to the outside of the protection tube 13, and the through groove 4 is connected to the inside of the protection tube 13. The wire of the receiving member 21 passes through the sealing groove 41 and the through groove 4, and enters the inside of the protection tube 13 from the outside of the protection tube 13. A sealing strip 42 for sealing the opening of the sealing groove 41 is placed and installed in the sealing groove 41. The sealing strip 42 and the sealing groove 41 are in an interference fit. The diameter of the opening surface of the sealing groove 41 is larger than the diameter of the opening surface of the through groove 4. The cross-sectional diameter of the sealing strip 42 adapted to the sealing groove 41 is also larger than the diameter of the opening surface of the through groove 4, so as to prevent the sealing strip 42 from falling into the through groove 4. The protection tube 13 is provided with a buckle 43 and a buckle groove 44 for buckling the buckle 43, and the buckle 43 is sunk into the outer wall of the protection tube 13. When the buckle 43 is buckled into the corresponding buckle groove 44, the buckle 43 is sunk below the height of the outer wall of the protection tube 13 to ensure the flatness of the outer wall of the protection tube 13. The part of the buckle 43 used to buckle into the buckle groove 44 is supported by spring steel to have deformation ability. The rotation axis of the buckle 43 and the buckle groove 44 are respectively distributed on both sides of the length direction of the sealing groove 41. The buckle 43 is used to press the sealing strip 42 into the sealing groove 41, that is, when the buckle 43 is buckled into the buckle groove 44, the buckle 43 passes from the sealing strip 42 toward the side wall outside the sealing groove 41 and contacts. The receiving part 21 that transmits data and supplies power through wires works most stably. When it is inconvenient to connect wires, it can also be powered by batteries and transmit data by wireless transmission.

[0060] Reference Figure 1 and Figure 3 and Figure 6, and the protection tube 13 on the pipe jacking machine does not have a through groove 4 and a sealing groove 41. If there are too many top plates, a relay room technology will be used, that is, an additional air cylinder or oil cylinder or jack is set between the top plates to perform segmented jacking during jacking. The protection tube 13 on the first top plate after segmentation also does not have a through groove 4 and a sealing groove 41, and the front end of this protection tube 13 is a sealing setting, and a transmitter 2 is fixedly connected therein, which is adapted to the sliding receiver 21 in other protection tubes 13 in the same segment for detection. Adjacent top plates can be sealed and fixedly connected by, for example, air pressure balance connection, mud water balance connection, earth pressure balance connection or other methods.

[0061] The data processing module 12 can be used in conjunction with a processor and a database, or a terminal device, such as a computer, to store various threshold data through a database, such as coordinate thresholds, correction thresholds, complete segment length data, top piece length data, warning thresholds, adjustment thresholds, tendency adjustment thresholds, etc. The processor is used to receive the received coordinate data, and then call the corresponding threshold data from the database, calculate the correction signal to give to multiple jacking cylinders 11, and realize the correction of the jacking direction by controlling the thrust of the multiple jacking cylinders 11.

[0062] The processor may include a central processing unit such as a CPU or MPU or a host system built around a CPU or MPU, including hardware or software. After the meter has a processor, people can freely control the metering instrument through programming to make it run according to people's wishes. The processor can control local measurement transmission, remote measurement transmission, remote communication, etc. through internal protocols. Internal protocols refer to all protocols that achieve mutual communication or links within the same metering instrument or the same system, including: human-computer interaction protocols, software / hardware (interface) protocols, chip bus (C-Bus) protocols, internal bus (I-Bus) protocols, etc. Part or all of the protocols. With the development of integrated circuit technology, some protocols that belong to the external bus (E-Bus) protocol are also classified as internal protocols after the external bus (E-Bus) is integrated into the chip.

[0063] The implementation principle of a pipe jacking construction correction device in an embodiment of the present application is as follows: when the top plate is pushed in, the trigger block 33 on the top plate is inserted into the trigger groove 34 and conflicts with the inclined inner wall of the retreat groove 35. At this time, the limit block 31 withdraws from the internal space of the protection tube 13, and then the wire of the receiving component 21 enters the protection tube 13 from the through groove 4 and the sealing groove 41, and then the sealing strip 42 is pressed into the sealing groove 41, and then the buckle 43 is buckled in the buckle groove 44. At this time, the top plate can be pushed into the soil, and then the receiving coordinate data is output to the processor through the receiving component 21 to control the pushing cylinder 11.

[0064] The present application embodiment discloses a method for rectifying deviation in pipe jacking construction. Figure 7The pipe jacking construction correction method includes the following steps:

[0065] S1, obtain receiving coordinate data;

[0066] S11, determining offset data by receiving coordinate data and a preset coordinate threshold;

[0067] S12, determining a correction signal through the offset data and a preset correction threshold and outputting it.

[0068] In detail: the received coordinate data refers to the coordinates of the infrared or laser reflected by the transmitter 2 on the receiver 21 received by the receiver 21. The coordinate threshold is the coordinate received by the receiver 21 after the transmitter 2 is fixed under the premise of ensuring that the protection tube 13 is straight. For example, the coordinate receiving range of the receiver 21 is (±200, ±200) mm. If the position of the infrared or laser or other signal received by the receiver 21 is (0,1) after the position of the transmitter 2 is fixed, (0,1) is used as the coordinate threshold to calculate the offset data. If the received coordinate data is (1,1), the offset data can be (1-0,1-1)=( 1,0), and since the pushing direction of the pushing cylinder 11 is the correct direction, the deviation is often caused by soil changes or pushing hard particles, which leads to the deviation of the forward direction of the pipe jacking machine. This deviation is accompanied by bending, so the transmitter 2 and the receiver 21 installed in the protective tube 13 can be detected in a variable direction, indicating that the x-coordinate is offset by one unit; the correction threshold is the influence of the thrust change of the pushing cylinder 11 on the deviation data. For example, the number of pushing cylinders 11 in this embodiment is four and they are distributed along the circumferential direction, named 1-4 respectively, and the correction thresholds are (No. 1, -x, 0), (No. 2, 0, -y), (No. 3, x, 0), (No. 4 ,0,y), the first correction threshold value indicates that when the thrust of the No. 1 push cylinder 11 is adjusted by percentage, the x-axis coordinate of the received coordinate data is affected by 1.0 times, and the y-axis coordinate will not be affected. For example, when the push cylinder 11 applies an additional 10% thrust, it will theoretically advance 10% more than other push cylinders 11. If the distance is a, it advances an additional 0.1a, and the impact on the x-axis coordinate is x=1*0.1a. The coordinate data that needs to be corrected can be determined from the offset data. If the correction coordinate is (1,0), it means that the x-axis coordinate that needs to be corrected is 1, and the y-axis coordinate does not need to be corrected, then The thrust applied to No. 1 push cylinder 11 can be inferred in reverse. Since No. 1 push cylinder 11 is opposite to No. 3 push cylinder 11, when No. 1 push cylinder 11 is pushed forward, an inclination angle will be generated. No. 2 push cylinder 11 and No. 4 push cylinder 11 between No. 1 push cylinder 11 and No. 3 push cylinder 11 will be driven and pushed outward, so corresponding thrust is also applied to No. 2 push cylinder 11 and No. 4 push cylinder 11. If the correction coordinate is (1,2), it means that the x-axis coordinate that needs to be corrected is 1, and the y-axis coordinate that needs to be corrected is 2, then additional force needs to be applied to No. 1 push cylinder 11 and No. 2 push cylinder 11 at the same time for control.

[0069] Reference Figure 8 , further comprising the following steps:

[0070] S2. Obtain technical data between relays;

[0071] S21, obtaining receiving coordinate data through relay room technical data, the receiving coordinate data including complete segment coordinate data and front top segment coordinate data;

[0072] S22, determining the complete segment offset angle data through the complete segment coordinate data, the coordinate threshold, and the preset complete segment length data;

[0073] S23, obtaining the data of the number of front top segment top pieces, and determining the data of the front top segment offset angle through the front top segment coordinate data, the coordinate threshold, the data of the number of front top segment top pieces, and the preset top piece length data;

[0074] S24, determining the offset angle data of the pipe jacking machine through the offset angle data of the complete section and the offset angle data of the front jacking section;

[0075] S25. Determine and output a correction signal based on the offset angle data and the correction threshold.

[0076] Details: First, determine whether the relay room technology is used. If not, the relay room technology data is 0. If it is used, the relay room technology data is 1. The relay room technology data is actively modified by the construction personnel after using additional cylinders or oil cylinders or jacks or other jacking equipment; if the relay room technology data is 1, it means that the relay room technology is used to jack the top piece in sections. At this time, the length of the section of the top piece and the jacking machine that is separated is fixed, and because there are separately controlled cylinders, they are calculated separately, and the current The received coordinate data received on the part that is pushed forward together with the top plate pushed into the construction starting well is the front top segment coordinate data, and the received coordinate data received on the part that has been segmented with a fixed length is the complete segment coordinate data; let the coordinate threshold be (0,1), let the complete segment length data be 10000, if the complete segment coordinate data is (1,1), it can be obtained that it is offset by 1 unit on the x-axis (the unit is mm, which means an offset of 1mm, and the complete segment length data is 10000mm=100m), then the trigonometric function can be obtained The complete segment offset angle data can be obtained as If the number of top pieces in the front top section is 5 and the top piece length is 1000, the length of the front top section can be obtained as 5*1000. If the coordinate data of the front top section is (1,1), the angle data of the front top section can be calculated as Then the offset angle data of the pipe jacking machine can be calculated as follows: Then, the correction signal is obtained by combining the correction threshold and then the correction control is performed. At this time, two methods can be used for correction. One is to use The sum of the deviation angle data is used as the correction signal to correct the push cylinder 11. The second method is to use As the deviation angle data, the correction signal is obtained to control the push cylinder 11, and then The correction signal obtained as the deviation angle data is used to perform correction control on the additional jacking equipment added in the section.

[0077] Reference Fig. 9 , further comprising the following steps:

[0078] S3, obtaining timing data;

[0079] S31, determining the offset speed data by receiving the coordinate data and the timing data;

[0080] S32, determining the deviation tendency data through the deviation speed data and the preset warning threshold;

[0081] S33, determining and outputting an offset signal through the offset tendency data and a preset adjustment threshold;

[0082] S34, obtaining the received coordinate data and timing data again to determine new offset speed data;

[0083] S35, determining the offset correction acceleration data through the original offset velocity data and the new offset velocity data;

[0084] S36, determining and outputting a new offset signal through the original offset speed data, the new offset speed data, the offset correction acceleration data, and the adjustment threshold until the received coordinate data is within the range of the coordinate threshold, and recording this calculation as fault data;

[0085] S37, determine and output an alarm signal through fault data, offset speed data, offset correction acceleration data, and adjustment threshold; S38, determine and output an alarm signal through offset speed data and a preset alarm threshold.

[0086] In detail: if the received coordinate data is (0,1), the timing data is the first second at this time; if the received coordinate data is (0,2), the timing data is the second second at this time; then the offset speed data can be calculated to be (2-1) / 1=1mm / s; the warning threshold is set to 0.5mm / s, 0.5<1, then the offset speed data exceeds the range of the warning threshold, and the offset tendency data that needs to be offset corrected is obtained; the adjustment threshold is set to 1%, indicating that the thrust of the push cylinder 11 corresponding to the x-axis coordinate offset needs to be increased or decreased by 1%, and then the received coordinate data and timing data are re-acquired to calculate the new offset speed data, that is, the third second; if the received coordinate data is (0,1.8) at this time, the distance of -0.2 is corrected on the x-axis, and the offset correction acceleration data is (1+(1+α)) / 2*1=-0.2, and α=-2.4mm / s is obtained. 2, the offset speed data is (1+(-2.4)) / 1=-1.2mm / s<0.5mm / s. It can be calculated that the original 1% thrust of the top cylinder 11 corrects the x-axis coordinate offset of 0.2 / 1=20%, resulting in -2.4mm / s 2 The acceleration of the cylinder 11 can be calculated to be theoretically able to return to the coordinate threshold and maintain the current force of the cylinder 11. Thus, t can be calculated, that is, the remaining coordinate offset of 0.8 needs to be maintained for t time to return to the coordinate threshold, so a new offset signal is obtained to adjust the push cylinder 11, and then the thrust of the push cylinder 11 returns to normal. If the same offset occurs again, it means a fault, and the work is stopped and an alarm signal is output; if the received coordinate data disappears instantaneously, for example, the received coordinate data is (0,1), the timing data is the first second at this time, if the received coordinate data is none, the timing data is the second second at this time, if the received coordinate data is none, the timing data is the third second at this time, and the alarm threshold is that the received coordinate disappears for more than 1s, and an alarm signal is output to prompt a fault.
