Description

Technical Field

[0001] The present application relates to the technical field of pipeline supports, and in particular to a pipeline protection structure for trench backfilling. Background Art

[0002] Trench backfilling is the process of backfilling the soil or other materials in the trench into the trench according to certain requirements after the pipeline is installed in the trench. The purpose is to protect the pipeline from the influence of the external environment, prevent the pipeline from mechanical damage and corrosion, etc., so as to extend the service life of the pipeline. At the same time, the correct backfilling method can also improve the stability of the pipeline and prevent the pipeline from deformation or damage when subjected to external loads.

[0003] However, in the actual construction process, the pipeline is placed at the bottom of the trench, and the bottom of the trench is difficult to be completely leveled. The pipeline will be partially suspended in the air, there will be bending stress inside the pipeline, and it is not easy to align the two pipelines, which will cause stress concentration in the pipeline after welding backfill, affecting the service life. Utility Model Content

[0004] In order to protect pipelines and reduce the occurrence of stress concentration, the present application provides a pipeline protection structure for trench backfilling.

[0005] The present application provides a pipeline protection structure for trench backfilling, which adopts the following technical solution:

[0007] A base, arranged at the bottom of the trench;

[0008] Telescopic rods are plugged into the base, and are provided in a group of two on each side of the pipe;

[0009] The support beam is in an arc shape with an opening upward, and its two ends are slidably connected to a group of telescopic rods. The sliding direction is the same as the extension direction of the support beam, and it is used to support the tube.

[0010] By adopting the above technical solution, setting up multiple protection structures, adjusting the length of the telescopic rod, and making each support beam rise to support the pipeline, the pipeline can be stably lifted up, and pipeline connection processes such as welding can be carried out. The bending stress of the pipeline is small. After backfilling under and on both sides of the pipeline, the backfill soil supports the pipeline. During the whole process, the protection structure can evenly support the pipeline and facilitate the adjustment of the position. After the backfilling is completed, the base is left in the soil layer, and the support beams and telescopic rods are pulled out and reused.

[0011] Optionally, the telescopic rod comprises:

[0012] The plug rod has a bottom end connected to the base and a top end provided with an external thread;

[0013] A threaded barrel, threadedly connected to the insertion rod;

[0014] The lifting ring is rotatably connected to the threaded cylinder and slidably connected to the support beam.

[0015] By adopting the above technical solution, the threaded tube can be screwed to make the threaded passage rise and fall, and the lifting ring can be lifted and lowered synchronously to drive the support beam to rise and fall and adjust the angle.

[0016] Optionally, the bottom end of the insertion rod is a pointed tip and passes through the base.

[0017] By adopting the above technical solution, the rod can be inserted into the soil layer, so that the rod can be better fixed in position, and at the same time, the base is not easy to deviate from the position, and the support for the pipeline is more stable.

[0018] Optionally, the base is provided with a socket for the insertion rod to be inserted, and a limit block is provided on the hole wall of the socket; a limit groove penetrating downward is provided on the side wall of the bottom end of the insertion rod, and the limit block is slidably inserted into the limit groove.

[0019] By adopting the above technical solution, the insertion rod is inserted into the insertion hole, and the limit block enters the limit groove until the limit block slides to the end of the limit groove, and the insertion rod is inserted into place. The limit groove can also stop the insertion rod from rotating, making it easier to screw the threaded barrel.

[0020] Optionally, a synchronization component is connected between the threaded barrels of the same group of telescopic rods, and the synchronization component is used to make the threaded barrels of the same group rotate synchronously.

[0021] By adopting the above technical solution, by screwing any threaded cylinder, the threaded cylinders in the same group can rotate synchronously, so that the threaded cylinders can lift the support beam more stably.

[0022] Optionally, the synchronization component includes:

[0023] There are two sprockets, each of which is detachably connected to a threaded barrel;

[0024] The chain is connected between two sprockets.

[0025] By adopting the above technical solution, the combination of the sprocket and chain can be transmitted more stably, and the sprocket can be removed after the backfilling is completed, so that the telescopic rods can be pulled out one by one.

[0026] Optionally, a pull plate is provided between two adjacent telescopic rods in different groups.

[0027] By adopting the above technical solution, the pull plate can enhance the overall structural strength of the telescopic rods on both sides of the pipeline, making it difficult for the telescopic rods to tilt or misalign.

[0029] By adopting the above technical solution, the pins are inserted into the soil layer at the bottom of the trench, so that the position of the base is not easily deviated, and the shaking of the base when the telescopic rod is adjusted can also be reduced.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.

[0038] This application proposes a pipeline protection structure for trench backfilling, referring to Figure 1 and Figure 2 , including a base 1, a telescopic rod 2 and a support beam 3. The base 1 is placed at the bottom of the trench; the telescopic rod 2 is plugged into the base 1; the support beam 3 is slidably connected to the upper part of the telescopic rod 2 to support the pipeline.

[0039] The base 1 is a rectangular frame placed at the bottom of the trench. A plurality of pins 13 are provided at the bottom of the base 1, and the pins 13 are inserted into the soil layer at the bottom of the trench, so that the base 1 is not easy to shake or shift. Four sockets 11 are provided on the base 1 for the telescopic rod 2 to be inserted.

[0040] The telescopic rod 2 includes an insert rod 21, a threaded tube 22, a lifting ring 23 and a receiving ring 24. The insert rod 21 is a round rod with a tip at the bottom and an external thread at the top, which is inserted into the socket 11. The diameter of the socket 11 is slightly larger than the diameter of the insert rod 21, so that when the base 1 is not horizontal, the insert rod 21 can be placed in a vertical state by fine-tuning the angle at which the insert rod 21 is inserted into the soil layer. The insert rod 21 is inserted into the soil layer, so that the insert rod 21 can be better fixed in position, and the base 1 is not easily deviated from the position, and the support for the pipeline is more stable. A limit groove 211 is provided on the side wall of the bottom end of the insert rod 21. The cross section of the limit groove 211 is rectangular, and the lower part passes through the tip of the insert rod 21. A limit block 12 is provided on the hole wall of the socket 11. The limit block 12 is slidably set in the limit groove 211, and the width is slightly smaller than the limit groove 211, so as to ensure that the insert rod 21 can be adjusted at a small angle in the socket 11. The insertion rod 21 is inserted into the insertion hole 11, and the limit block 12 enters the limit groove 211 until the limit block 12 slides to the top of the limit groove 211, and the insertion rod 21 is inserted into place. The limit groove 211 can also stop the insertion rod 21 from rotating, making it easier to screw the threaded tube 22.

[0041] The bottom end of the threaded barrel 22 is open, and an internal thread is provided inside, which is threadedly connected to the insertion rod 21. The top of the threaded barrel 22 is integrally formed with a hexagonal screwing portion 221, which is convenient for construction personnel to use a wrench to screw the threaded barrel 22. The lifting ring 23 is rotatably connected to the side wall of the threaded barrel 22 and is coaxial with the threaded barrel 22. A sliding column 231 is integrally formed radially on the circumferential outer wall of the lifting ring 23, and a sliding cap 232 is integrally formed at the end of the sliding column 231 away from the lifting ring 23. The receiving ring 24 is rotatably connected to the outer wall of the threaded barrel 22, and is used to receive the pull plate 5.

[0042] The telescopic rods 2 are provided in two groups, each group having two, which are respectively inserted into the four insertion holes 11. Two threaded tubes 22 in the same group are slidably connected to one end of the support beam 3.

[0043] The support beam 3 is an arc-shaped beam with both ends bent upward, which is used to support and support the pipeline. T-shaped grooves are provided on both sides of the support beam 3. The extension direction of the T-shaped grooves is the same as the extension direction of the support beam 3, so that the sliding track of the support beam 3 is the same as its own extension direction, which is convenient for pulling out the support beam 3 after backfilling. The sliding column 231 and the sliding cap 232 are slidably inserted into the T-shaped groove. When the threaded cylinder 22 is raised and lowered, the corresponding end of the support beam 3 can be lifted, and the height and horizontal angle of the pipeline on the support beam 3 can be adjusted. Pull rings 31 are welded on both ends of the support beam 3, which can facilitate the construction personnel to pull out the support beam 3 after completing the backfilling of the bottom and both sides of the pipeline.

[0044] The synchronization assembly 4 includes a sprocket 41 and a chain 42. Each group of synchronization assemblies 4 is provided with two sprockets 41, and the two sprockets 41 are respectively arranged on the same group of threaded barrels 22, and the chain 42 is connected between the two sprockets 41. The sprocket 41 is inserted into the threaded barrel 22, and a slot is provided on the threaded barrel 22. A corresponding block is provided on the sprocket 41. When the block is inserted into the slot, the threaded barrel 22 and the sprocket 41 can rotate synchronously. A support ring 25 is also welded on the threaded barrel 22, and the support ring 25 is used to support the chain 42, so that the chain 42 is not easily decoupled due to its own gravity.

[0045] The pull plate 5 is a long strip, and two of them are connected between different groups of threaded tubes 22 on both sides of the support beam 3. Both ends of the pull plate 5 are provided with openings along the width direction, and the threaded tubes 22 are clamped in the openings. The receiving ring 24 supports the pull plate 5, which can enhance the overall structural strength of the telescopic rods 2 on both sides of the support beam 3, so that the telescopic rods 2 are not easy to tilt and misalign.

[0046] The method of using the protective structure of the embodiment of the present application is as follows: place the base 1 at the bottom of the trench, insert the pin 13 into the soil layer and fix it firmly. Insert the plug rods 21 of the four telescopic rods 2 vertically into the insertion hole 11, insert the tip of the plug rod 21 into the soil layer, adjust the position of the lifting ring 23, align the T-slot entrance on the support beam 3 with the sliding column 231 and the sliding cap 232 of the lifting ring 23, and then install the support beam 3 on the two groups of telescopic rods 2. Install the two pull plates 5 on the threaded cylinder 22. Install the synchronization component 4 on the telescopic rods 2 of the same group. Set up multiple protective structures in the trench in turn, then put the pipeline on the support beam 3 of each protective structure, adjust each telescopic rod 2, so that each support beam 3 evenly supports the pipeline and aligns with the adjacent pipeline. After the pipeline welding is completed, backfill the bottom and both sides of the pipeline, and the backfill soil is not higher than the two ends of the support beam 3. After ensuring that the backfill soil can support the pipeline, remove the synchronization component 4, pull out the support beam 3, and finally pull out the telescopic rod 2. Except for the base 1, the remaining parts can be reused.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
