Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground pipeline laying, and in particular to an auxiliary structure for pipe jacking and exiting the tunnel. Background Technology
[0002] Pipe jacking technology is widely used in urban underground pipe networks and tunnel construction, especially in situations where excavation is inconvenient and disruption to surface traffic or existing facilities is undesirable, making it a common construction method. Pipe jacking uses mechanical equipment to push the pipe from the starting point to the target location, completing the laying of underground pipelines or other facilities. However, the successful completion of pipe jacking construction, particularly during the "exit" process, is affected by soil stability, which impacts construction efficiency and quality, and can even threaten the safety of the project.
[0003] During pipe jacking, the surrounding soil may be disturbed, and changes in soil stress and ground settlement may adversely affect the surrounding environment. This not only threatens the safety of the construction process but may also lead to pipeline settlement, tilting, or even damage. Therefore, optimizing the exit stage of pipe jacking construction to ensure the smooth and accurate exit of the pipeline has become an urgent problem to be solved. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies where soil is prone to settlement, and to propose an auxiliary structure for pipe jacking and tunneling.
[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:
[0006] A pipe jacking auxiliary structure includes a support base, two pairs of compaction rollers on one side of the support base, and a transmission assembly for driving the two pairs of compaction rollers to rotate synchronously on the other side of the support base. The transmission assembly has a gear ring and two pairs of gears meshing with it. The two pairs of gears are respectively fixedly connected to the two pairs of compaction rollers. The support base is provided with an installation assembly for fixing the device to the pipe to be jacked out.
[0007] Preferably, the transmission assembly includes a fixed frame, a motor housing, and a drive motor. The fixed frame is rotatably mounted on the end face of the support seat and is rotatably connected to two pairs of compaction rollers. The gear ring is fixedly mounted on the support seat, and the motor housing is slidably mounted on the support seat. The end face where the motor housing and the support seat are connected is curved and completely fits the connection point with the support seat. The drive motor is fixedly mounted inside the motor housing, and the output shaft of the drive motor is fixedly connected to a gear.
[0008] Preferably, the two pairs of gears are arranged in a matrix on the outside of the gear ring.
[0009] Preferably, the mounting assembly includes a flange and a plurality of fixing slots. The flange is fixedly connected to the bearing seat, and the plurality of fixing slots are all formed on the flange and are located on the mounting holes provided on the flange.
[0010] Preferably, the compaction roller is provided with a plurality of alternating protrusions for compacting the soil layer.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, a drive motor drives a gear to rotate, which revolves around a gear ring. This gear, through a fixed frame, drives the remaining gears to rotate as well, so that all gears rotate and revolve synchronously. The gears drive the compaction roller to rotate, and the compaction roller rotates on its own axis and revolves around the axis of the bearing seat. The outermost part of the compaction roller continuously rolls and compacts the inner wall of the hole, compacting the loose soil layer inside the hole. This prevents soil stress changes and ground settlement from having adverse effects on the surrounding environment, thus ensuring the safety of pipe jacking construction. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] Example: This example provides an auxiliary structure for pipe jacking exiting the hole, see [link / reference]. Figure 1-3 Specifically, it includes a support base 1, with two pairs of compaction rollers 11 on one side of the support base 1, and a transmission assembly for driving the two pairs of compaction rollers 11 to rotate synchronously on one side of the support base 1. The transmission assembly contains a gear ring 21 and two pairs of gears 22 meshing with it. The two pairs of gears 22 are fixedly connected to the two pairs of compaction rollers 11 respectively. The support base 1 is provided with an installation assembly for fixing the device to the pipe to be ejected.
[0021] The transmission component drives two pairs of compaction rollers 11 to rotate. The compaction rollers 11 rotate on their own axis and revolve around the axis of the bearing seat 1. The outermost part of the compaction rollers 11 continuously rolls and compacts the inner wall of the hole, compacting the loose soil layer inside the hole, avoiding the adverse effects of soil stress changes and ground settlement on the surrounding environment, and ensuring the safety of pipe jacking construction.
[0022] The transmission assembly includes a fixed frame 2, a motor box 23, and a drive motor 24. The fixed frame 2 is rotatably mounted on the end face of the bearing seat 1. The fixed frame 2 is rotatably connected to two pairs of compaction rollers 11. The gear ring 21 is fixedly mounted on the bearing seat 1. The motor box 23 is slidably mounted on the bearing seat 1. The end face of the motor box 23 connected to the bearing seat 1 is curved and completely fits the connection with the bearing seat 1. The drive motor 24 is fixedly mounted inside the motor box 23. The output shaft of the drive motor 24 is fixedly connected to a gear 22.
[0023] The drive motor 24 drives a gear 22 to rotate. Since the gear 22 meshes with the gear ring 21, the gear 22 will revolve around the gear ring 21. The gear 22 drives the remaining gears 22 to rotate through the fixed frame 2. The fixed frame 2 restricts the remaining gears 22 to also revolve around the gear ring 21. The remaining gears 22 rotate on their own axis under the restriction of meshing with the gear ring 21, so that the rotation and revolution of all gears 22 are synchronized. The two pairs of gears 22 drive the two pairs of compaction rollers 11 to rotate. When the gears 22 revolve, the gears 22 will drive the motor box 23 to rotate along the support seat 1.
[0024] Two pairs of gears 22 are arranged in a matrix on the outside of the gear ring 21;
[0025] The gears 22 are distributed in a matrix pattern and are equidistantly distributed on the outside of the toothed ring 21. The gears 22 can drive the compaction roller 11 to compact the inner wall of the hole evenly, which has a good effect on the compaction of the soil.
[0026] The mounting assembly includes a flange 3 and multiple mounting slots 31. The flange 3 is fixedly connected to the bearing seat 1. The multiple mounting slots 31 are all opened on the flange 3 and are all located on the mounting holes provided on the flange 3.
[0027] When installing the device, the bearing seat 1 can be fixed to the end of the pipe to be "exited" through the flange 3, and the bolt head is located in the fixing groove 31, which does not affect the normal movement of the motor box 23.
[0028] The compaction roller 11 is provided with multiple alternating protrusions for compacting the soil layer;
[0029] The protrusions on the compaction roller 11 exert a strong squeezing and kneading effect on the soil. This action can more effectively compact the soil and improve its density and bearing capacity.
[0030] Specifically, the working principle and operation method of this utility model are as follows:
[0031] The drive motor 24 drives a gear 22 to rotate. This gear 22 revolves around the gear ring 21. This gear 22 drives the remaining gears 22 to rotate through the fixed frame 2, so that all gears 22 rotate and revolve synchronously. The gears 22 drive the compaction roller 11 to rotate. The compaction roller 11 rotates on its own axis and revolves around the axis of the bearing seat 1. The outermost part of the compaction roller 11 continuously rolls and compacts the inner wall of the hole, compacting the loose soil layer inside the hole. This prevents soil stress changes and ground settlement from having an adverse impact on the surrounding environment and ensures the safety of pipe jacking construction.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
