Description

Technical Field

[0001] The utility model relates to the field of civil construction equipment, in particular to an underground pipeline support and protection mechanism. Background Art

[0002] When constructing underground drainage pipes in soft soil or sandy strata, a concrete cushion is often laid first, followed by the pipes. After the pipes are laid, a secondary concrete pouring process is performed to further secure the pipes in the stratum. This ensures that the pipes are stably fixed in the stratum after construction. For example, a soft soil drainage pipe foundation structure disclosed in Application No. 202221485383.2 pre-builds a reinforced concrete foundation (i.e., cushion) in the construction stratum. After the pipes are laid, a concrete wrapping layer is poured to secure the pipes.

[0003] During the construction process using heavy-duty rigid pipes such as cement pipes, the pipes pre-placed in the cushion layer are easily disturbed and displaced, or even partially rolled, during the process of placing the new pipes into the centering interface, causing the pipes to deviate from the predetermined position. Currently, during construction, workers often use wooden wedges inserted into the bottom of the pipe to limit the position. However, due to the heavy weight of the pipe, this method is difficult and dangerous to manually limit the position using wooden wedges. Based on this, the applicant provides an underground pipeline support and protection structure that has solved the problems existing in the existing technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an underground pipeline support and protection mechanism, which can provide stable support for the already placed pipelines to prevent the pipelines from shifting during the centering process of the newly placed pipelines, thereby reducing the labor intensity and difficulty of personnel and effectively solving the existing problems.

[0005] The top surface of the lower support block is set to be an inclined surface, so that when the lower support block is arranged on the cushion layer on the lower side of the pipeline, the inclined surface can abut and limit the position of the lower end of the pipeline; the upper support member is arranged on the upper side of the lower support block, and the upper support member has a limiting portion abutting against the side surface of the pipeline; a connecting bracket, wherein the connecting bracket includes a fixing portion that can be detachably connected to the cushion layer, and the connecting bracket can connect the lower support block and the upper support block; wherein at least one of the upper support member and the lower support block can be slidably arranged with the connecting bracket in the horizontal direction, and the connecting bracket also includes an adjustable limiting member, which can be switched between a limited state and an unlocked state, and when the limiting member is in the limited state, the limiting member can stop the slidable upper support member and / or the lower support block from moving in a direction away from the pipeline.

[0006] Furthermore, the lower support block is slidably connected to the connecting bracket.

[0007] Furthermore, the limiting member includes a limiting bolt threadedly engaged with the connecting bracket, and the limiting bolt can abut against the lower support block to limit the position when in the limiting state.

[0008] Furthermore, the connecting bracket includes a base frame connected to the lower support block, a first strut and a second strut connected to the base frame, and the upper ends of the first strut and the second strut are connected to the upper support member, so that the first strut and the second strut, the base frame, and the upper support member form a triangular support structure.

[0009] Furthermore, the upper support member includes a connecting portion connected to the connecting bracket and a supporting portion hinged to the connecting portion, and the supporting portion can abut against the side surface of the pipe.

[0010] Furthermore, the support portion includes a support frame and support protrusions provided at upper and lower ends of the support frame, and the support protrusions can abut against the side surfaces of the pipe.

[0011] Furthermore, the connecting bracket includes a base frame connected to the lower support block, the fixing part includes a slider slidably arranged on the base frame, and a support bolt threadedly engaged with the base frame, the slider is provided with a mounting hole, and the support bolt can abut against the slider to stop the base frame from moving away from the pipeline relative to the slider.

[0012] Furthermore, the base frame is provided with a slide groove, and a pressing rib is formed on the top of the sliding block to press on the base frame.

[0013] The beneficial effect of the utility model is that it can provide stable support for the already placed pipeline to prevent the pipeline from being displaced during the process of centering the interface of the newly placed pipeline, thereby reducing the labor intensity and difficulty of personnel and effectively solving the existing problems.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0023] In this utility model, if Figure 1-2 As shown, a support and protection mechanism for an underground pipeline 11 is provided, comprising: a lower support block 1, the top surface of the lower support block 1 being arranged as an inclined surface 101, so that when the lower support block 1 is arranged on the cushion layer on the lower side of the pipeline 11, the inclined surface 101 can abut against the side surface of the lower end of the pipeline 11 for limiting position; an upper support member, the upper support member being arranged on the upper side of the lower support block 1, the upper support member having a limiting portion abutting against the side surface of the pipeline 11; a connecting bracket, the connecting bracket comprising a fixing portion that can be detachably connected to the cushion layer, the connecting bracket being capable of connecting the lower support block 1 and the upper support member; wherein, at least one of the upper support member and the lower support block 1 can be slidably arranged in the transverse direction with the connecting bracket, the connecting bracket also comprising an adjustable limiting member, the limiting member being capable of switching between a limited state and an unlocked state, and the limiting member being capable of stopping the slidably arranged upper support member and / or lower support block 1 from moving in a direction away from the pipeline 11 when in the limited state.

[0024] When using the support and protection structure for an underground pipeline 11 of the present invention, the protection structure is placed to the side of the end of the pipeline 11, so that one of the lower support block 1 and the upper support member (when one of the lower support block 1 and the upper support member is slidably connected to the connecting bracket, the other is selected as the member that abuts the side of the pipeline 11) first abuts the side of the pipeline 11, and then the fixing portion is installed and fixed between the cushion layer. Then, the other of the lower support block 1 and the upper support member is abutted against the side of the pipeline 11 to complete the support and fixation of the pipeline 11.

[0025] Taking the illustrated embodiment as an example, the upper support member is first abutted against the side of the pipe 11, and then the fixing portion is connected and fixed to the cushion layer. Then, the lower support block 1 is slid to abut against the side of the pipe 11 and fixed. The lower support block 1 is limited by the limiting member to complete the fixation of the pipe 11.

[0026] After the newly inserted pipe 11 is placed on the cushion layer and the interface is aligned, the fixing portion can be removed from the cushion layer and the entire supporting and protecting mechanism can be removed.

[0027] The support and protection mechanism of the utility model has the following technical effects:

[0028] First, the present invention fixes the lower support block 1 and the upper support member by fixing the connecting bracket to the cushion layer. Compared with the existing method of manually holding wooden wedges, the difficulty and intensity of personnel operation are reduced, and the operator can be kept away from the pipeline 11, thereby reducing the risk of personnel operation and forming a protection for the staff.

[0029] Secondly, the present invention adopts a combination of the lower support block 1 and the upper support member to support and limit the position. The lower support block 1 can be used to directly limit and support the lower section of the pipe 11. The friction generated by the contact between the lower support block 1 and the cushion layer can further improve the stability of the lateral deviation limit of the pipe 11. The upper support member can increase the limiting torque for stopping the pipe 11 when it rolls, thereby stably supporting and fixing the pipe 11 to prevent the pipe 11 from shifting.

[0030] Third, by setting at least one of the upper support member and the lower support block 1 to be slidable, the upper support member and the lower support block 1 can be conveniently adjusted separately during installation, so that when the upper support member and the lower support block 1 cannot stably contact the side of the pipeline 11 at the same time due to uneven cushioning, only adjustment is required to stably support the pipeline 11.

[0031] In the embodiment shown in the figure, for the structure of the present invention, more specifically, the lower support block 1 is slidably connected to the connecting bracket. As shown in the figure, the lower support block 1 is connected to two slide bars, which slide through the connecting bracket.

[0032] In the illustrated embodiment, with respect to the structural arrangement of the limiting member, to be more specific, the limiting member includes a limiting bolt 2 threadedly engaged with the connecting bracket, and the limiting bolt 2 can abut against the lower support block 1 for limiting position when in the limiting state.

[0033] As shown in the figure, by setting a limit bolt 2, after the upper support member is abutted against the side of the pipe 11, the limit bolt 2 can be screwed into the direction of the pipe 11 so that the lower support block 1 can abut against the lower section of the pipe 11 for a limit position.

[0034] In the illustrated embodiment, the structure of the present invention is further specifically described as follows: the connecting bracket includes a base frame 3 connected to the lower support block 1, a first support rod 4 and a second support rod 5 connected to the base frame 3, and the upper ends of the first support rod 4 and the second support rod 5 are connected to the upper support member, so that the first support rod 4 and the second support rod 5, the base frame 3, and the upper support member form a triangular support structure. As shown in the figure, this allows the triangular support structure to stably support the upper support member, thereby further improving the stability of the upper support member's position limiting support.

[0035] In the illustrated embodiment, a further optimized configuration of the present invention is that the upper support member includes a connecting portion 6 connected to the connecting bracket and a supporting portion 7 hingedly connected to the connecting portion 6, wherein the supporting portion 7 is capable of abutting against the side surface of the pipe 11. As shown in the figure, by hingedly connecting the supporting portion 7 to the connecting portion 6, the supporting portion 7 can maintain a stable abutment state with the curved surface portion of the side surface of the pipe 11, thereby preventing the supporting portion 7 from making virtual contact with the side surface of the pipe 11.

[0036] In the illustrated embodiment, with respect to the structure of the present invention, more specifically, the support portion 7 includes a support frame 701 and support protrusions 702 provided at the upper and lower ends of the support frame 701. The support protrusions 702 are capable of abutting against the side of the pipe 11. As shown in the figure, the two support protrusions 702 can abut against the side of the pipe 11, so that the support portion 7 can stably abut against the side of the pipe 11.

[0037] In the illustrated embodiment, a further optimized setting of the present invention is that the connecting bracket includes a base frame 3 connected to the lower support block 1, the fixing portion includes a slider 8 slidably arranged on the base frame 3, and a support bolt 9 threadedly engaged with the base frame 3, the slider 8 is provided with a mounting hole 10, and the support bolt 9 can abut against the slider 8 to stop the base frame 3 from moving away from the pipe 11 relative to the slider 8.

[0038] As shown in the figure, when installing the connecting bracket on the cushion layer, after the slider 8 is initially fixed to the cushion layer (such as by passing the fixing bolt 14 through the mounting hole 10 of the slider 8 and then initially fixing it to the cushion layer), the connecting bracket is slid relative to the slider 8 so that the upper support member abuts against the side of the pipe 11, and then the slider 8 is tightened on the cushion layer and abutted against the slider 8 by the support bolt 9, so that the upper support member and the pipe 11 are stably abutted and limited.

[0039] Regarding the installation method of the slider 8, in the illustrated embodiment, to be more specific, as shown in the figure, the base frame 3 is provided with a slide groove 12, and the top of the slider 8 is formed with a pressing rib 13 that is pressed against the base frame 3.

[0040] As shown in the figure, when the slider 8 is connected and fixed to the cushion layer by the fixing bolt 14, the nut of the fixing bolt 14 can press the base frame 3 onto the cushion layer through the pressure rib 13 of the slider 8, further improving the stability of the connection bracket fixation.

[0041] In the accompanying drawings, in order to better illustrate the structure, Figure 1 The position of the slider in the protective mechanism on the middle right side is shown in partial section, and the limit bolt is drawn with a dotted line. Figure 2 In the figure, the pipeline is blurred on the right side.

Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are generally similar to the method embodiments, so the description is relatively simple.

[0043] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
