[0045] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] Embodiment 1

[0047] See also Figures 1 to 7 The pipeline internal penetration device provided by the embodiment of the present invention comprises an external pipe 1, an internal pipe 2 and a pulling assembly 3. The inner wall of the external pipe 1 is provided with a guide groove 11, and the guide groove 11 extends along the axial direction of the external pipe 1; the internal pipe 2 can be penetrated in the external pipe 1, and a guide member 4 is detachably provided on the outer periphery of the internal pipe 2, and the guide member 4 can be slidably connected with the guide groove 11; the pulling assembly 3 is detachably connected with the internal pipe 2, and the pulling assembly 3 can drive the internal pipe 2 to move along the axial direction of the external pipe 1.

[0048] The pipe inner-penetrating device proposed in the present invention is slidably connected with the detachable guide member 4 on the outer periphery of the inner-penetrating pipe 2 through the guide groove 11 extending along the axial direction arranged on the inner wall of the external pipe 1, so as to provide precise guidance for the movement of the inner-penetrating pipe 2, and effectively solves the problem of low axis control accuracy of the inner-penetrating steel pipe in the prior art, thereby ensuring that the inner-penetrating pipe 2 always maintains the correct axis position during the movement and installation process; the traction component 3 is detachably connected to the inner-penetrating pipe 2, and can drive the inner-penetrating pipe 2 to move axially along the external pipe 1, thereby improving the efficiency of pipeline transportation and docking.

[0049] The specific structure of the pipeline penetration device is described below.

[0050] See also Figure 2 The external pipe 1 includes a plurality of sections of pipe bodies, which are interconnected along the axial direction of the external pipe 1, and the guide grooves 11 of each pipe body are arranged one by one and coaxially. On the one hand, the design of the multi-section pipe body makes the transportation and installation of the external pipe 1 more flexible and convenient. At the construction site, facing the complex environment and limited space, the large integral external pipe 1 may be difficult to transport and install in place, while the segmented pipe body can be more conveniently transported to the designated location and assembled on site, thereby improving the convenience and efficiency of construction. On the other hand, the guide grooves 11 that are arranged one by one and coaxially ensure that the inner pipe 2 can maintain a consistent and accurate guide when passing through the multi-section pipe body. Even if it passes through the connection parts 42 of multiple pipe bodies, the movement of the inner pipe 2 will not be affected, and it can still move smoothly along the predetermined axis, thereby improving the accuracy and stability of the axis control of the inner pipe 2.

[0051] It is understandable that in other embodiments, the external pipe 1 can also be an integral pipe. Specifically, the external pipe 1 can be a shield, a water pipe, etc., which is not limited here. It only needs to ensure that the inner diameter of the external pipe 1 is larger than the outer diameter of the inner pipe 2 to facilitate the penetration effect of the inner pipe 2.

[0052] See also Figure 3 The guide groove 11 is formed on the inner wall of the outer tube body, and the opening of the guide groove 11 protrudes inward to form a limiting protrusion 111. The limiting protrusion 111 can limit the radial movement of the guide member 4 along the guide groove 11, and can effectively prevent the inner tube 2 from being misaligned in the radial direction under the interference of external forces in the construction environment, so as to more stably maintain the predetermined position, further improving the accuracy of the control of the axis of the inner tube 2. At the same time, it avoids problems such as pipeline collision and dislocation caused by the radial movement of the guide member 4, reduces safety hazards in construction, and reduces construction risks.

[0053] Specifically, the inner wall of the guide groove 11 extends in an arc shape. The arc-shaped inner wall can make the contact between the guide member 4 and the guide groove 11 smoother, reducing friction and wear. During the process of passing through the pipeline, when the guide member 4 slides along the guide groove 11, the smooth contact can reduce resistance, making the movement of the inner pipe 2 smoother, thereby improving the efficiency of construction, while also reducing the loss of the guide member 4 and the guide groove 11 caused by friction, and extending the service life of the device. In other embodiments, the side wall of the guide groove 11 can also be extended vertically or bent, etc., which is not limited here.

[0054] In addition, there is no limitation on the number of the guide grooves 11 , and it is only necessary to ensure that a guide groove 11 is provided for each guide member 4 .

[0055] See also Figure 4 and Figure 5 , about the inner tube 2. A clamping groove 21 is provided on the outer periphery of the inner tube 2, and the clamping groove 21 extends along the axial direction of the inner tube 2, and the guide member 4 is clamped in the clamping groove 21. The design of the clamping groove 21 provides a clear installation position and a stable connection method for the guide member 4. The clamping structure can ensure that the guide member 4 is firmly fixed in the clamping groove 21, and prevent the guide member 4 from loosening or falling off during the process of passing through the pipeline, thereby ensuring the reliability of the guiding function and improving the stability and accuracy of the movement of the inner tube 2.

[0056] Specifically, the diameter of the slot 21 gradually decreases in the direction away from the inner pipe 2, and the slot 21 can limit the radial movement of the guide member 4 along the slot 21, thereby enhancing the stability of the guide member 4 in the slot 21, so that it will not shake or deviate radially due to external forces during the process of passing through the pipeline, ensuring that the inner pipe 2 always moves along the predetermined axis, and improving the accuracy of the control of the axis of the inner pipe 2. Secondly, the gradually closing slot 21 structure can prevent the guide member 4 from accidentally falling out, increasing the safety of construction.

[0057] Regarding the specific structure of the guide member 4, the guide member 4 includes a support plate 41 and two connecting parts 42, the two connecting parts 42 are respectively arranged at both ends of the support plate 41, one connecting part 42 is connected to the guide groove 11, and the other connecting part 42 is connected to the clamping groove 21. The design of the support plate 41 and the two connecting parts 42 increases the contact area between the guide member 4 and the guide groove 11 and the clamping groove 21, making the force distribution more uniform, and reducing the wear and deformation of the guide member 4 caused by excessive local pressure.

[0058] It is worth noting that in this embodiment, the two connecting portions 42 are respectively configured to be conformal to the guide groove 11 and the clamping groove 21 , so as to facilitate the matching of the guide groove 11 and the clamping groove 21 .

[0059] Specifically, multiple groups of guide members 4 are arranged at intervals along the axial direction of the inner tube 2, which can provide uniform and continuous guiding support for the inner tube 2 at different positions, so that the inner tube 2 can maintain a stable axial position during the entire axial movement process, thereby improving the accuracy and reliability of the axis control. Each group is provided with multiple guide members 4 arranged at intervals along the circumference of the inner tube 2, which constrain and guide the inner tube 2 from multiple directions. This all-round guiding effect effectively prevents the shaking and deviation of the inner tube 2 in the circumferential direction, and further enhances the stability and accuracy of the movement of the inner tube 2.

[0060] See also Figure 7 , about the traction assembly 3. The traction assembly 3 includes a tractor 31 and a support trolley 32. The tractor 31 and the support trolley 32 are connected by a connecting rope 33. The tractor 31 can pull the support trolley 32 to move in the horizontal plane, and the support trolley 32 can be detachably arranged on the bottom surface of the inner tube 2. As a power source, the tractor 31 can provide a strong and continuous pulling force, while the support trolley 32 provides stable support and guidance at the bottom. The two work together to effectively avoid the inner tube 2 from shaking, deflecting and other unstable phenomena during the traction process, thereby ensuring the stability and accuracy of the movement of the inner tube 2. The support trolley 32 is detachably arranged on the bottom surface of the inner tube 2, which facilitates the assembly and disassembly of the device. It can be quickly installed before construction and can be easily dismantled after the construction is completed, thereby improving the efficiency of construction.

[0061] It is understandable that both the tractor 31 and the support vehicle 32 are existing equipment in the art, and their specific structures and working principles are not described in detail here.

[0062] Embodiment 2

[0063] The embodiment of the present invention further provides a pipeline internal penetration construction method, using the above-mentioned pipeline internal penetration device, and the specific steps are as follows:

[0064] Before step 1, during the stage of designing and on-site production of the external pipe 1, a guide groove 11 needs to be reserved in the pipe segment. The pre-buried guide groove 11 is full-length in the pipe to facilitate the later movement of the inner pipe 2 inside it along the axial direction.

[0065] Afterwards, the external pipe 1 is constructed first, and when the pipe segments are assembled, all the guide grooves 11 should be aligned to ensure that all the guide grooves 11 are coaxially arranged. In addition, when the inner pipe 2 is processed, the arc surface of the inner pipe 2 periphery needs to be welded with a slot 21.

[0066] It is worth noting that the stress conditions of the inner pipe 2 should be taken into consideration during the design phase of the external pipe 1, which should not only meet the requirements of withstanding the external soil pressure, but also take into account the stress conditions of other working conditions such as the weight and transportation of the inner pipe 2; during the advancement of the external pipe 1, all guide grooves 11 should be kept in the same position, and the deviation should not be too large, so as to ensure the smooth movement of the inner pipe 2; in addition, the guide member 4 should be set to a separate adjustment type and adjusted according to the axial condition of the pipeline.

[0067] Step 1: Install the guide member 4 onto the inner tube 2, and connect the inner tube 2 to the traction assembly 3;

[0068] In this step, first, one of the connecting parts 42 of the guide member 4 is snapped onto the snap-in groove 21 of the inner tube 2 . After the guide member 4 is installed, the inner tube 2 is placed and fixed on the supporting vehicle 32 .

[0069] Step 2: Connect the guide member 4 to the guide groove 11, and drive the traction assembly 3 to drive the inner tube 2 to move along the inside of the outer tube 1 until the inner tube 2 moves to the target position;

[0070] In this step, the other connecting portion 42 of the guide member 4 is connected to the guide groove 11 on the inner wall of the external tube 1. After the connection is completed, the tractor 31 is driven to drive the support vehicle 32 to move along the inside of the external tube 1 until the inner tube 2 moves to the target position.

[0071] Step 3: fix the inner tube 2, disassemble the inner tube 2 and the traction assembly 3, and drive the traction assembly 3 to move out of the external tube 1.

[0072] In this step, the inner pipe 2 is fixed, and the inner pipe 2 and the support vehicle 32 are removed, and the tractor 31 is driven to drive the support vehicle 32 to move out of the outer pipe 1;

[0073] Step 4: After the construction of the inner pipe 2 is completed, the gap between the inner pipe 2 and the outer pipe 1 is filled.

[0074] See also Figures 8 to 10 In this step, first, the filling material 5 is used to fill the inner bottom wall of the external tube 1 from bottom to top. After the height of the filling material 5 is flush with the guide groove 11 at the bottom of the external tube 1, the guide member 4 at the bottom of the external tube 1 is removed; after the guide member 4 is removed, continue to fill upward until the height of the filling material 5 is flush with the bottom of the guide member 4 at the upper part of the external tube 1, remove all remaining guide members 4, and then continue to fill upward until the gap between the inner tube 2 and the external tube 1 is filled with the filling material 5.

[0075] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
