Description

Technical Field

[0001] This invention relates to the field of underground pipeline construction technology, and in particular to a micro-pipe jacking construction device and method. Background Technology

[0002] With the continuous improvement of urban infrastructure construction, the laying and renovation of underground pipelines are increasing. In the construction of underground pipelines, the traditional excavation method will have a significant impact on urban roads, traffic order and the surrounding environment. Moreover, the construction cycle is long and the restoration cost is high. Therefore, trenchless construction technology is widely used in underground pipeline crossing construction because of its advantages such as less disturbance to the surrounding environment, high construction efficiency and no need for large-scale excavation.

[0003] Existing micro-pipe jacking construction devices still have many shortcomings in practical applications: First, the guiding accuracy is low. During construction, the pipe sections are easily affected by factors such as soil resistance and uneven jacking force, which can easily lead to problems such as deviation and tilting. As a result, the pipeline laying accuracy cannot meet the design requirements, and a lot of adjustment work is required later. In addition, during construction, due to the uneven output force, it is necessary to use structures such as pads to assist in supporting the pipeline. However, this jacking method is inefficient and has poor stability. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the prior art, when construction operations are carried out, the output force is not balanced, and structures such as pads are needed to assist in supporting the pipeline. However, this jacking method is inefficient and has poor stability. Therefore, a micro-jacking construction device and method are proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A miniature pipe jacking construction device includes a support mechanism, a reaction mechanism fixedly connected to the top of the support mechanism, a pipe jacking mechanism fixedly connected to the right side of the reaction mechanism, the pipe jacking mechanism for clamping and jacking pipe fittings, the support mechanism for supporting the reaction mechanism and the pipe jacking mechanism, a moving mechanism slidably disposed at the top of the support mechanism for moving laterally along the support mechanism, an installation mechanism fixedly disposed at the top of the moving mechanism, and a support mechanism also mounted at the top of the installation mechanism. The installation mechanism and the support mechanism together form a support and lifting structure for the pipe fittings.

[0007] Preferably, the support mechanism includes a mounting groove, a guide rail, and a guide groove. There are two support mechanisms, and the two support mechanisms are arranged in a linear array. The mounting groove is opened inside the support mechanism. There are two guide rails, and the two guide rails are fixedly arranged in a linear array at the top of the two support mechanisms. The guide grooves are symmetrically opened on the front and rear sides of each guide rail.

[0008] Preferably, the main body of the reaction mechanism is an arc-shaped structure. The reaction mechanism is used to fit against the inner wall of the construction well. The reaction mechanism includes a reaction guide rail, a height adjustment push rod, a connecting support, a guide slider, and a mounting base plate. The reaction guide rail is arranged longitudinally and is fixedly installed on the inner wall of the support mechanism.

[0009] Preferably, the reaction guide rail has a longitudinal groove inside, the height adjustment push rod is fixedly installed in the longitudinal groove of the reaction guide rail, the connecting support is slidably installed in the reaction guide rail, and the top end of the connecting support is fixedly connected to the bottom end of the height adjustment push rod.

[0010] Preferably, there are two guide sliders, which are symmetrically fixed on the front and rear sides of the connecting support, and the mounting base is fixedly fixed on one end of the connecting support.

[0011] Preferably, the pipe jacking mechanism includes a support base, a locator, a guide frame, a clamping push rod, a clamping plate support arm, and construction pipe fittings. The pipe jacking mechanism is a hydraulic pipe structure. The support base is fixedly installed at the output end of the pipe jacking mechanism. A groove is provided on the right side of the support base, and a locator is fixedly connected inside the groove. The locator is a laser positioning structure.

[0012] Preferably, the guide frame is provided in four locations, and the four guide frames are fixedly arranged in a circular array on the outer wall of the support base. The clamping push rod is fixedly arranged inside the guide frame, and the clamping plate support arm is slidably arranged inside the guide frame. One end of the clamping plate support arm is fixedly connected to the clamping push rod, and the construction pipe fittings are clamped and limited on the inner side of both the clamping push rod and the clamping plate support arm.

[0013] Preferably, the moving mechanism includes a transmission slider, a moving guide wheel, a servo motor, and a support base. The main body of the moving mechanism is a U-shaped structure with a one-way opening at the bottom. The transmission slider is symmetrically fixedly disposed on the inner wall of the moving mechanism and slides along the guide groove. The moving guide wheel is rotatably disposed on the inner side of the moving mechanism. The servo motor is fixedly disposed at one end of the moving mechanism and is used to drive the moving guide wheel to move along the guide rail. The support base is fixedly disposed at the top of the two moving mechanisms.

[0014] Preferably, the installation mechanism includes a lifting hydraulic rod, a connecting guide plate, and a sliding support. The installation mechanism is fixedly installed at the top of the bearing base. The lifting hydraulic rod is hinged within the installation mechanism. The connecting guide plate is hinged to the output end of the lifting hydraulic rod. The sliding support is fixedly installed at the top of the connecting guide plate. The support mechanism includes a guide groove and a limiting bracket. The guide groove is opened at the bottom of the support mechanism and is used for the sliding support to slide. The limiting bracket is used for temporarily lifting and limiting the construction pipe fitting.

[0015] This invention discloses a method for using a micro-pipe jacking construction device, comprising the following steps:

[0016] S1. Device positioning and installation: Place the support mechanism in the preset construction position, build the installation foundation of the whole device through the two linear array structures of the support mechanism, and use the installation slots inside the support mechanism to fit and install the auxiliary components required for construction, ensuring that the support mechanism provides stable support for the reaction mechanism and the pipe jacking mechanism.

[0017] S2. Debugging of reaction mechanism: Start the height adjustment push rod of the reaction mechanism. The height adjustment push rod extends and retracts in the longitudinal groove of the reaction guide rail, driving the connecting support fixedly connected to it to slide longitudinally along the reaction guide rail. The guide sliders on the front and rear sides of the connecting support slide synchronously along the corresponding slide groove of the reaction guide rail. Adjust the height of the reaction mechanism to match the size of the construction well, so that the arc-shaped body of the reaction mechanism fits tightly against the inner wall of the construction well. Securely connect the reaction mechanism and the pipe jacking mechanism through the mounting plate.

[0018] S3. Jacking direction calibration: Start the locator of the pipe jacking mechanism. The locator emits a laser beam to accurately calibrate the jacking direction of the construction pipe fittings, providing a reference trajectory for the accurate jacking of subsequent construction pipe fittings.

[0019] S4. Lifting position adjustment: Start the servo motor of the moving mechanism. The servo motor drives the moving guide wheel to roll along the guide rail of the support mechanism. At the same time, the transmission slider on the inner wall of the moving mechanism slides synchronously along the guide grooves on the front and rear sides of the guide rail, driving the moving mechanism to move laterally along the support mechanism, so that the installation mechanism and the support mechanism on the top bearing base of the moving mechanism move to the preset lifting position of the construction pipe.

[0020] S5. Lifting Height Adaptation: Activate the lifting hydraulic rod of the installation mechanism. The lifting hydraulic rod extends and retracts, driving the hinged connecting guide plate to adjust the angle. The sliding support at the top of the connecting guide plate slides along the guide groove at the bottom of the lifting mechanism, driving the lifting mechanism to adjust its height. This makes the limiting bracket of the lifting mechanism fit the shape of the construction pipe fitting, achieving temporary lifting and limiting of the construction pipe fitting.

[0021] S6. Construction pipe clamping: Activate the clamping push rod of the jacking mechanism. The clamping push rod extends and retracts within the guide frame, pushing the clamping plate support arm fixedly connected to it to slide inward along the guide frame. The clamping plate support arms corresponding to the four circular arrays of the guide frame move synchronously, forming a uniform clamping force on the construction pipe from all sides, thus completing the stable positioning of the construction pipe.

[0022] S7. Pipe jacking operation: Start the hydraulic drive system of the pipe jacking mechanism. The pipe jacking mechanism transmits the jacking force evenly to the construction pipe through the support base, pushing the construction pipe through the soil in the direction marked by the locator. At the same time, the reaction mechanism provides a stable reaction force through the arc structure that fits the inner wall of the construction well, which counteracts the force generated by the pipe jacking mechanism during jacking and prevents the device from shifting.

[0023] S8. Dynamic lifting coordination: During the jacking process of the construction pipe fittings, the moving mechanism continuously adjusts its position according to the jacking progress, driving the installation mechanism and the support mechanism to move synchronously, maintaining the lifting support of the construction pipe fittings. The lifting hydraulic rod can flexibly adjust the extension and retraction amount according to the posture changes of the construction pipe fittings. The height and angle of the support mechanism can be finely adjusted by connecting the guide plate and the sliding support to ensure that the construction pipe fittings always maintain a stable posture.

[0024] S9. Real-time trajectory correction: During the jacking process, the positioner monitors the direction of the construction pipe in real time. If a slight deviation occurs, the jacking trajectory of the construction pipe is corrected in real time by adjusting the height adjustment push rod to change the support height of the reaction mechanism, adjusting the clamping force of the clamping push rod, or adjusting the lifting position of the moving mechanism, so as to ensure that the construction pipe advances along the designed trajectory.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In this invention, by setting up components such as a support mechanism, a moving mechanism, an installation mechanism, and a support mechanism, and through the sliding cooperation between the guide rails and guide grooves of the support mechanism and the transmission sliders and moving guide wheels of the moving mechanism, the fixed connection between the bearing base of the moving mechanism and the installation mechanism, and the coordinated action of the lifting hydraulic rod, connecting guide plate, and sliding support of the installation mechanism and the guide slide groove and limiting bracket of the support mechanism, the moving mechanism can drive the installation mechanism and the support mechanism to flexibly adjust their lateral positions along the support mechanism, the lifting hydraulic rod can drive the support mechanism to achieve height adjustment, and the limiting bracket can form a stable lifting limit for the construction pipe. This device can replace the traditional pad block-assisted lifting method through the technical linkage of each mechanism, which not only solves the technical problems of poor lifting stability and low efficiency in traditional construction, but also achieves precise matching of lifting position and height, ensuring that the construction pipe maintains a stable posture during the jacking process.

[0027] 2. In this invention, by setting up components such as a pipe jacking mechanism and a reaction mechanism, and through the linkage of the locator of the pipe jacking mechanism with the clamping push rod and the clamping plate support arm, the locator first accurately calibrates the jacking direction of the construction pipe. The clamping push rod drives the clamping plate support arm to form a uniform clamping force on the construction pipe. At the same time, the reaction mechanism's reaction guide rail, height adjustment push rod, connecting support and mounting base cooperate, and the arc-shaped reaction mechanism fits against the inner wall of the construction well to provide a stable reaction force, balancing the unbalanced force generated by the pipe jacking mechanism during jacking. This device can effectively offset the influence of soil resistance on the construction pipe through the technical linkage of positioning, clamping and reaction support, solving the technical problems of low guiding accuracy and easy deviation and tilting of pipe sections in the prior art, greatly reducing the amount of adjustment work in the later stage, and ensuring that the pipeline laying accuracy meets the design requirements.

[0028] 3. In this invention, by setting up components such as a support mechanism, a reaction mechanism, a pipe jacking mechanism, a moving mechanism, an installation mechanism, and a support mechanism, the support mechanism provides basic support for the overall device, the reaction mechanism provides reaction force guarantee for the pipe jacking mechanism, the pipe jacking mechanism is responsible for clamping and jacking in the construction pipes, and the moving mechanism, installation mechanism, and support mechanism work together to lift and adapt the construction pipes. The various mechanisms form a full-process technical linkage of support, reaction force, positioning, clamping, lifting, and jacking. This device can realize integrated operation of construction pipe installation through the coordinated operation of multiple mechanisms, which not only improves the continuity and efficiency of construction, but also further enhances the stability and accuracy of construction through the precise coordination of each link. Compared with the existing technology, it has significant innovation in the comprehensive performance of trenchless pipe jacking construction and provides a more reliable technical solution for underground pipeline construction.

[0040] Furthermore, the support mechanism 1 includes a mounting groove 101, a guide rail 1011, and a guide groove 1012. There are two support mechanisms 1, and the two support mechanisms 1 are arranged in a linear array. The mounting groove 101 is opened inside the support mechanism 1. There are two guide rails 1011, and the two guide rails 1011 are fixedly arranged in a linear array at the top of the two support mechanisms 1. The guide grooves 1012 are symmetrically opened on the front and rear sides of each guide rail 1011. By adopting the support mechanism 1 arranged in a linear array, as well as the mounting groove 101 inside, the two guide rails 1011 at the top, and the guide grooves 1012 on the front and rear sides of the guide rails 1011, a stable installation and sliding foundation is provided for the moving mechanism 4, ensuring the smooth lateral movement of the moving mechanism 4.

[0041] Furthermore, the main body of the reaction mechanism 2 is an arc-shaped structure. The reaction mechanism 2 is used to fit against the inner wall of the construction well. The reaction mechanism 2 includes a reaction guide rail 201, a height adjustment push rod 2011, a connecting support 2012, a guide slider 2013, and a mounting base plate 2014. The reaction guide rail 201 is arranged longitudinally and is fixedly installed on the inner wall of the support mechanism 1. By adopting the reaction mechanism 2 with an arc-shaped main body, the longitudinally arranged reaction guide rail 201 is fixed to the inner wall of the support mechanism 1. With the help of the height adjustment push rod 2011, the connecting support 2012, the guide slider 2013, and the mounting base plate 2014, the fit with the inner wall of the construction well and the height adjustment are realized, which enhances the stability of the reaction support during construction.

[0042] Furthermore, a longitudinal groove is provided inside the reaction guide rail 201. The height adjustment push rod 2011 is fixedly installed in the longitudinal groove of the reaction guide rail 201. The connecting support 2012 is slidably installed in the reaction guide rail 201. The top end of the connecting support 2012 is fixedly connected to the bottom end of the height adjustment push rod 2011. By opening a longitudinal groove inside the reaction guide rail 201 and fixing the height adjustment push rod 2011 in the groove, and by slidably installing the connecting support 2012 in the reaction guide rail 201 with its top end fixed to the bottom end of the height adjustment push rod 2011, stable longitudinal lifting and lowering adjustment of the connecting support 2012 is achieved.

[0043] Furthermore, there are two guide sliders 2013, which are symmetrically fixed on the front and rear sides of the connecting support 2012. The mounting base 2014 is fixed on one end of the connecting support 2012. By symmetrically fixing two guide sliders 2013 on the front and rear sides of the connecting support 2012 and fixing the mounting base 2014 at one end, the guiding of the connecting support 2012 during sliding and the installation stability of the mounting base 2014 are ensured.

[0044] Furthermore, the pipe jacking mechanism 3 includes a support base 301, a locator 3011, a guide frame 3012, a clamping push rod 3013, a clamping plate support arm 3014, and a construction pipe fitting 3015. The pipe jacking mechanism 3 is a hydraulic pipe structure. The support base 301 is fixedly installed at the output end of the pipe jacking mechanism 3. A groove is provided on the right side of the support base 301. The locator 3011 is fixedly connected inside the groove. The locator 3011 is a laser positioning structure. By using the pipe jacking mechanism 3 with a hydraulic pipe structure, the support base 301 is fixed at its output end, and the locator 3011 with a laser positioning structure is fixed in the groove on the right side of the support base 301, which achieves accurate positioning when the construction pipe fitting 3015 is jacked in, thus improving the guiding accuracy.

[0045] Furthermore, four guide frames 3012 are provided in total. The four guide frames 3012 are fixedly arranged in a circular array on the outer wall of the support base 301. The clamping push rod 3013 is fixedly arranged inside the guide frame 3012. The clamping plate support arm 3014 is slidably arranged inside the guide frame 3012. One end of the clamping plate support arm 3014 is fixedly connected to the clamping push rod 3013. The construction pipe fitting 3015 is clamped and limited on the inner side of both the clamping push rod 3013 and the clamping plate support arm 3014. By fixing the four guide frames 3012 in a circular array on the outer wall of the support base 301, fixing the clamping push rod 3013 inside the guide frame 3012, and slidably arranging the clamping plate support arm 3014 inside the guide frame 3012 with one end fixed to the clamping push rod 3013, the construction pipe fitting 3015 is stably clamped and limited, ensuring the stability of the pipe fitting during the insertion process.

[0046] Furthermore, the moving mechanism 4 includes a transmission slider 401, a moving guide wheel 4011, a servo motor 4012, and a support base 4013. The main body of the moving mechanism 4 is a U-shaped structure with a one-way opening at the bottom. The transmission slider 401 is symmetrically fixedly disposed on the inner wall of the moving mechanism 4 and slides along the guide groove 1012. The moving guide wheel 4011 is rotatably disposed on the inner side of the moving mechanism 4. The servo motor 4012 is fixedly disposed at one end of the moving mechanism 4 and is used to drive the moving guide wheel 4011 along the guide groove 1012. The track component 1011 moves, and the bearing base 4013 is fixedly set at the top of the two moving mechanisms 4. The moving mechanism 4 adopts a U-shaped structure with a one-way opening at the bottom. The transmission slider 401, which is symmetrically fixed on the inner wall, slides along the guide groove 1012. The moving guide wheel 4011, which is rotatably set on the inner side, is driven by the servo motor 4012 to move along the guide track component 1011. The bearing base 4013 is fixed at the top, which realizes the stable lateral movement of the moving mechanism 4 along the support mechanism 1, and drives the installation mechanism 5 and the support mechanism 6 to move synchronously.

[0047] Furthermore, the installation mechanism 5 includes a lifting hydraulic rod 501, a connecting guide plate 5011, and a sliding support 5012. The installation mechanism 5 is fixedly installed at the top of the bearing base 4013. The lifting hydraulic rod 501 is hinged within the installation mechanism 5, the connecting guide plate 5011 is hinged to the output end of the lifting hydraulic rod 501, and the sliding support 5012 is fixedly installed at the top of the connecting guide plate 5011.

The support 5012 slides, and the limiting bracket 6011 is used to temporarily lift and limit the construction pipe fitting 3015. The lifting hydraulic rod 501 of the installation mechanism 5 is hinged to the top of the bearing base 4013, and the output end is hinged to the guide plate 5011. The top of the sliding support 5012 is fixed, and the guide groove 601 at the bottom of the support mechanism 6 allows the sliding support 5012 to slide. The limiting bracket 601 temporarily lifts and limits the construction pipe fitting 3015, realizing flexible lifting and limiting of the construction pipe fitting 3015, improving the lifting stability and adjustment convenience.

[0048] This invention discloses a method for using a micro-pipe jacking construction device, comprising the following steps:

[0049] S1. Device positioning and installation: Place the support mechanism 1 at the preset construction position, build the installation foundation of the whole device through the two linear array structures of the support mechanism 1, and use the installation groove 101 inside the support mechanism 1 to adapt and install the auxiliary components required for construction, so as to ensure that the support mechanism 1 provides stable support for the reaction mechanism 2 and the pipe jacking mechanism 3.

[0050] S2. Debugging of the reaction mechanism: Start the height adjustment push rod 2011 of the reaction mechanism 2. The height adjustment push rod 2011 extends and retracts in the longitudinal groove of the reaction guide rail 201, driving the connecting support 2012 fixedly connected to it to slide longitudinally along the reaction guide rail 201. The guide sliders 2013 on the front and rear sides of the connecting support 2012 slide synchronously along the corresponding slide grooves of the reaction guide rail 201. Adjust the height of the reaction mechanism 2 to match the size of the construction well, so that the arc-shaped body of the reaction mechanism 2 fits tightly against the inner wall of the construction well. The reaction mechanism 2 and the pipe jacking mechanism 3 are stably connected by the mounting base plate 2014.

[0051] S3, jacking direction calibration: Activate the positioner 3011 of the jacking mechanism 3. The positioner 3011 emits a laser beam to accurately calibrate the jacking direction of the construction pipe fitting 3015, providing a reference trajectory for the accurate jacking of the subsequent construction pipe fitting 3015.

[0052] S4. Lifting position adjustment: Start the servo motor 4012 of the moving mechanism 4. The servo motor 4012 drives the moving guide wheel 4011 to roll along the guide rail 1011 of the support mechanism 1. At the same time, the transmission slider 401 on the inner wall of the moving mechanism 4 slides synchronously along the guide grooves 1012 on the front and rear sides of the guide rail 1011, driving the moving mechanism 4 to move laterally along the support mechanism 1, so that the installation mechanism 5 and the support mechanism 6 on the top support base 4013 of the moving mechanism 4 move to the preset lifting position of the construction pipe 3015.

[0053] S5. Lifting Height Adaptation: The lifting hydraulic rod 501 of the installation mechanism 5 is activated. The lifting hydraulic rod 501 extends and retracts, driving the hinged connecting guide plate 5011 to adjust its angle. The sliding support 5012 at the top of the connecting guide plate 5011 slides along the guide groove 601 at the bottom of the support mechanism 6, driving the support mechanism 6 to adjust its height, so that the limiting bracket 6011 of the support mechanism 6 fits the shape of the construction pipe fitting 3015, realizing the temporary lifting and limiting of the construction pipe fitting 3015.

[0054] S6. Construction pipe clamping: Start the clamping push rod 3013 of the jacking mechanism 3. The clamping push rod 3013 extends and retracts within the guide frame 3012, pushing the clamping plate support arm 3014 fixedly connected to it to slide inward along the guide frame 3012. The clamping plate support arms 3014 corresponding to the four circular arrays of the guide frame 3012 move synchronously, forming a uniform clamping force on the construction pipe fitting 3015 from all sides, completing the stable positioning of the construction pipe fitting 3015.

[0055] S7. Pipe jacking operation: Start the hydraulic drive system of pipe jacking mechanism 3. Pipe jacking mechanism 3 transmits uniform jacking force to construction pipe fitting 3015 through support base 301, pushing construction pipe fitting 3015 through the soil along the direction marked by locator 3011. At the same time, reaction mechanism 2 provides stable reaction force through the arc structure that fits the inner wall of construction well, offsetting the force generated by pipe jacking mechanism 3 during jacking and preventing device displacement.

[0056] S8. Dynamic lifting coordination: During the jacking process of the construction pipe fitting 3015, the moving mechanism 4 continuously adjusts its position according to the jacking progress, driving the installation mechanism 5 and the support mechanism 6 to move synchronously, maintaining the lifting support of the construction pipe fitting 3015. The lifting hydraulic rod 501 can flexibly adjust the extension and retraction amount according to the posture change of the construction pipe fitting 3015. The height and angle of the support mechanism 6 are finely adjusted by connecting the guide plate 5011 and the sliding support 5012 to ensure that the construction pipe fitting 3015 always maintains a stable posture.

[0057] S9. Real-time trajectory correction: During the jacking process, the positioner 3011 monitors the direction of the construction pipe 3015 in real time. If a slight deviation occurs, the jacking trajectory of the construction pipe 3015 is corrected in real time by adjusting the height adjustment push rod 2011 to change the support height of the reaction mechanism 2, adjusting the clamping force of the clamping push rod 3013, or adjusting the lifting position of the moving mechanism 4, so as to ensure that the construction pipe 3015 advances along the designed trajectory.

[0058] In use, the support mechanism 1 serves as the basic load-bearing component of the overall device. Its two linear array structures provide a stable installation platform for the reaction mechanism 2 and the pipe jacking mechanism 3. The internal installation groove 101 can be adapted to the installation of auxiliary components in the construction scenario. The two guide rails 1011 at the top and the guide grooves 1012 symmetrically opened on the front and rear sides of each guide rail 1011 together constitute the sliding guide foundation of the moving mechanism 4, ensuring that the moving mechanism 4 always maintains a stable trajectory during lateral movement and avoids deviation.

[0059] The reaction mechanism 2, as the core of the reaction support in pipe jacking construction, has an arc-shaped main structure that can closely fit the inner wall of the construction shaft, maximizing the contact area to disperse the force generated during jacking. The reaction guide rail 201 is longitudinally fixed to the inner wall of the support mechanism 1, and the longitudinal groove inside provides installation space for the height adjustment push rod 2011. When the height adjustment push rod 2011 extends or retracts, it drives the connecting support 2012, which is fixedly connected to its top, to slide longitudinally along the reaction guide rail 201, realizing flexible adjustment of the reaction support height to adapt to construction shaft environments of different sizes. Two guide sliders are symmetrically fixed on the front and rear sides of the connecting support 2012. 2013, can be embedded in the corresponding groove of the reaction guide rail 201, effectively limiting the sliding trajectory of the connecting support 2012, avoiding swaying or deviation during lifting, and ensuring the stability of reaction force transmission. The mounting plate 2014 fixed at one end of the connecting support 2012 acts as a connecting bridge, firmly connecting the reaction mechanism 2 and the jacking mechanism 3, so that the force generated by the jacking mechanism 3 when jacking can be transmitted to the connecting support 2012 through the mounting plate 2014, and then transmitted to the inner wall of the construction well through the reaction guide rail 201 and the arc structure, forming a balanced reaction force support to offset the risk of device displacement caused by the jacking force;

[0060] The pipe jacking mechanism 3, as the actuator for clamping and jacking pipe fittings, adopts a hydraulic pipe structure to ensure sufficient and stable jacking force. The support base 301 is fixed to the output end of the pipe jacking mechanism 3. A laser positioning structure locator 3011, fixed in a groove on its right side, can emit a laser beam to mark the jacking direction of the construction pipe fitting 3015 at the initial stage of construction, providing a benchmark for subsequent precise laying. Four guide frames 3012, fixed in a ring array on the outer wall of the support base 301, provide installation and sliding guidance for the clamping push rod 3013 and the clamping plate support arm 3014. After the clamping push rod 3013 is activated, it will push the corresponding... The fixedly connected clamping arm 3014 slides inward along the guide frame 3012, and the clamping arms 3014 corresponding to the four guide frames 3012 move synchronously, forming a uniform clamping force on the construction pipe fitting 3015 from all sides. This avoids the problem of pipe fitting deformation or displacement caused by uneven force in the traditional clamping method, and realizes the stable positioning of the construction pipe fitting 3015. After the clamping action is completed, the hydraulic drive system of the pipe jacking mechanism 3 is started, and the uniform jacking force is transmitted to the construction pipe fitting 3015 through the support base 301, pushing the construction pipe fitting 3015 through the soil in the direction marked by the locator 3011.

[0061] The moving mechanism 4 is responsible for driving the installation mechanism 5 and the support mechanism 6 to adjust the lifting position. Its U-shaped structure with a one-way opening at the bottom can be locked onto the guide rail 1011 of the support mechanism 1 to ensure installation stability. The transmission slider 401, which is symmetrically fixed on the inner wall of the moving mechanism 4, is embedded in the guide groove 1012 of the support mechanism 1. The moving guide wheel 4011, which is rotatably set on the inner side, is in contact with the surface of the guide rail 1011. When the servo motor 4012 is started, it will drive the moving guide wheel 4011 to roll along the guide rail 1011. At the same time, the transmission slider 401 slides synchronously along the guide groove 1012. The two work together to realize the smooth lateral movement of the moving mechanism 4 along the support mechanism 1. The bearing base 4013 fixed at the top of the moving mechanism 4 provides a stable installation plane for the installation mechanism 5, ensuring that the installation mechanism 5 and the moving mechanism 4 move synchronously, thereby driving the support mechanism 6 to accurately adjust the lifting position to adapt to the lifting needs of different parts of the construction pipe fitting 3015.

[0062] The installation mechanism 5 and the support mechanism 6 together form the support and lifting structure for the pipe fitting, providing auxiliary support for the pipe fitting during construction. The installation mechanism 5 is fixed to the top of the bearing base 4013. The internally hinged lifting hydraulic rod 501 can extend and retract flexibly. The connecting guide plate 5011 hinged at its output end can adjust the angle with the extension and retraction of the lifting hydraulic rod 501. The sliding support 5012 fixed at the top of the connecting guide plate 5011 is embedded in the guide groove 601 opened at the bottom of the support mechanism 6. When the lifting hydraulic rod 501 extends and retracts or the angle of the connecting guide plate 5011 is adjusted, the sliding support 5012 can slide in the guide groove 601 to achieve fine adjustment of the height and angle of the support mechanism 6. The limiting bracket 6011 of the support mechanism 6 adopts a structural design that adapts to the shape of the construction pipe fitting 3015, which can form a close-fitting lifting and limiting of the construction pipe fitting 3015, avoiding problems such as sinking or displacement of the pipe fitting due to gravity or soil resistance during the jacking process.

[0063] Throughout the construction process, the various mechanisms work together in a closed-loop manner: First, the support mechanism 1 completes the positioning and installation of the entire device; the reaction mechanism 2 adjusts the height according to the dimensions of the construction well and fits against the well wall; the locator 3011 of the pipe jacking mechanism 3 calibrates the jacking direction; the moving mechanism 4 drives the installation mechanism 5 and the support mechanism 6 to move to the preset lifting position; the lifting hydraulic rod 501 drives the support mechanism 6 to adjust the height, so that the limit clamp 6011 lifts the construction pipe fitting 3015 to the calibrated height; then, the clamping push rod 3013 of the pipe jacking mechanism 3 drives the clamping plate support arm 3014 to clamp and fix the construction pipe fitting 3015; and the pipe jacking mechanism 3 starts the hydraulic drive to advance... During the jacking operation, the reaction mechanism 2 provides a stable reaction force to counteract the jacking force, the support mechanism 6 continuously lifts and limits the movement, and the moving mechanism 4 moves synchronously according to the jacking progress to maintain support. During the jacking process, the locator 3011 monitors the direction of the construction pipe 3015 in real time. If a slight deviation occurs, it can be corrected by adjusting the height of the reaction mechanism 2, the clamping force of the jacking mechanism 3, or the lifting position of the moving mechanism 4 to ensure that the construction pipe 3015 always advances along the designed trajectory. The precise actions and coordinated operation of each mechanism realize the precise, stable, and efficient construction of the micro-jacking pipe crossing, fully covering all the needs of the entire construction process.
